VMware ESXi 5.1 U1 Release and HP Custom ESXi Image

VMware released ESXi 5.1 U1 in April earlier this year,  HP also released a custom image of this release that incorporates customised HP drivers and management software saving you time to download and install the software yourself. A good point to make is that by using the customised HP Proliant ESXi image – this is a step towards keeping consistency in the software/driver level in your VMware environment. This is best practices in my opinion.

The custom image is available on the VMware site.

Not all server’s are created equal! For compatible HP Proliants, always check compatibility on the following website:

Now here’s where it gets cool – You can build your own HP Custom image of the ESXi image! Just head over to allowing you to add comptabile HP bundles for VMware Image Builder, Update Manager and ESXCLI etc.



For those who have upgraded to 5.1 U1 (Custom and Non-custom image) please be aware of the following: – Cannot log in to vCenter Server using the domain username/password credentials via the vSphere Web Client/vSphere Client after upgrading to vCenter Server 5.1 Update 1 (2050941)




Trending Virtualization VMWare

VMware Horizon Mobile and Switch

About a month ago, VMware announced two new “VMware Ready” devices for their VMware Horizon Mobile software,  although Apple iPhones are still yet to make an appearance in this list – this is still something I am very excited about. Firstly, because its an area where I am still technically upskilling  and secondly because I see mobility as an area which is on the verge of exploding.

Switch to VMware with VMware Switch

Put simply, VMware Switch (not to be confused with a VMware vSwitch 🙂 allows multiple personalities or persona to exist on the same mobile hardware device.

Now think back to my post on the trends in storage and cloud computing for 2013, I noted at the time that VMware Horizon was opening up new doors to the mobile user, EUC as we know it is changing tremendously.

The possibilities could be endless.

Think segregation, think defined work schedules, think BYOD – Now as an avid user of BYOD myself (Apple Fanboy here) I truely am excited to see VMware extend their  virtualization technology to mobile devices. Technology is fuelled by innovation, and to me this is innovation. Almost every IT/Technologist/Enthuiast has at least one mobile device.  I sat on the tram the other day and was astonished (but not surprised) at at least 90% of the fellow passengers glued to their mobile device – Facebooking, tweeting, reading news, email etc  All thirsty for information and social interaction.

Our mobiles no longer just serve the purpose of being able to phone and speak to someone, we make decisions on buying these mobile devices on other capabilities such as SMS, web browsing, email capabilities and social media access. Exciting times!!!

Cloud Personal Trending Virtualization VMWare

vExpert 2013 award






Yesterday, VMware announced this years awardees with the prestigious  vExpert 2013 title, an award that has been around since 2009 to recognise individuals on their contributions to the global virtualization and cloud community.  The list is put together by VMware and in particular John Troyer (@JohnTroyer) and the VMware Social Media & Community Team- No easy task in my mind as there are a lot of great VMware practitioners and Evangelists out there.


Announcement link (Just in case you dont believe me 🙂


For me, this is my very first year being recognised in this category, and I am very humbled and honoured to be recognised among some of the great evangelists in this field – some who are personal friends of mine which makes it even more special.


Does it mean you’re now an expert?

No, not necessarily.  The title is not based on what you know or how much you know.  A great extract from the announcement page shows what it takes (and doesnt take) to be recognised:

“A vExpert not a technical certification or even a general measure of VMware expertise. The judges selected people who were particularly engaged with their community and who had developed a substantial personal platform of influence in those communities. There were a lot of very smart, very accomplished people, even VCDXs, that weren’t named as vExpert this year” (Retrieved from


Lastly, I would also like to extend my congratulations out to all of the other vExperts for 2013. Looking forward to meeting some of you over the next year.



3PAR DR HP Storage Virtualization VMWare

HP 3PAR peer persistence v1: peering into the persisting world of 3PAR


Time for a technical deep dive – As you may or may not know, HP 3PAR boasts a sexy array-based software feature set. You’ve probably heard me rave on about it in other posts and podcasts I have done.  I’ve worn this fan-boy cap for a while now and spoken about our leading thin suite.


Some 3PAR software features perhaps don’t get as much limelight as our thinning capability or wide striping but they are extremely supportive and tell a great benefit story, especially in the area of High Availability (HA) or Business Continuity (BC). These features are array based and are called peer persistence, peer motion, persistent ports and persistent cache.


The names appear similar but they mean different solutions so let’s take a look at some of these concepts and how they work particularly with the vSphere platform—starting with peer persistence.


Spotlight on HP 3PAR Peer Persistence

Another way to look at peer persistence is to tie it back to something that has been around for a while in the virtual world – VMware vMotion technology.


So what vMotion does for local site workloads, peer persistence does for geographically disparate data centres, meaning it offers transparent site switchover without the application knowing it has happened. It provides a HA configuration between these sites in a metro-cluster configuration.


Peer persistence allows you to extend this coverage across two sites, enabling use of your environment and load balancing your virtual machines (VMs) across disparate arrays. Truly a new way to think of a federated data center in this context IMO.  Note, this implies an active\active configuration at the array level but not at the volume level, which is active\passive which infers hosts paths to the primary volume and secondary volume


Transparent switchover and Zero RPO/RTO

What does it mean to offer “transparent site failover”? In the context of 3PAR peer persistence, it simply means that workloads residing in a VMware cluster can shift from site 1 to  site 2 without downtime. This makes aggressive RPO\RTOs an achievable reality.

This is particular fit for mission-critical applications or services that may have this RTO/RPO of 0.


















Note: I mention VMware for this as this particular technology only currently supports VMware hosts (vSphere 5.0+) and not vMSC.


How does it do it?

Peer persistence leverages HP 3PAR remote copy synchronous to manage the transfer of the remote from local site to remote site and gain acknowledgement back to the host operating system (vSphere in this instance). Today the switchover is a manual process executed via the 3PAR CLI (the automated process is coming later this year).


Working with VMware vSphere, this allows your ESXi cluster to virtually span across data centers. So in the above figure VMs are being serviced by HP StoreServ Storage A and other VMs are being serviced by HP StoreServ Storage B  but all are existing in the same VMware data center.  Moving VMs between sites would typically need a reset, but peer persistence removes this limitation by continuous copying or shadowing the VM on the remote volume via RC and switching over the volumes logically.


I’ll write the high level process with the above figure 1 in mind without any pretty pictures:


  • Host can logically see both HP StoreServ Storage arrays by means of stretch fabric.
  • VM resides in Site 1, on Volume A. Volume A’s partner (Volume B) is being presented to Host B in Site 2 and can be considered active but not primary.
  • The primary and secondary volumes are exported using different Target Port Groups supported by persona 11 (VMware).


This presentation is possible via Asymmetric Logical Unit Access or ALUA allowing a SCSI device (Volume A in this instance) to be masked with same traits (Source WWN).


Provided this configuration exists, the process is:

  1. Controlled switchover is initiated by user manually via CLI on primary array. Using ‘setrcopygroup switchover <groupname>’
  2. IO from the host to the primary array is blocked and in flight IO is allowed to drain.
  3. The remote copy group is stopped and snapshots are taken on the primary array.
  4. The primary array target port group is changed to transition state.
  5. The primary array sends a remote failover request to the secondary array.
  6. The secondary array target port group is changed to transition state.
  7. The secondary array takes a recovery point snapshot.
  8. The secondary array remote copy group changes state to become primary-reversed (pri-rev).  At this point the secondary volume will become read/write.
  9. The secondary target port group is changed to active state.
  10. The secondary array returns a failover complete message to the primary array.
  11. From here, The primary array target port group is changed to standby state and any blocked IO is returned to the host with the following sense error: “NOT READY, LOGICAL UNIT NOT ACCESSIBLE, TARGET PORT IN STANDBY STATE”
  12. The host will perform SCSI inquiry requests to detect what target port groups have changed and which paths are now active.  Getting your host multipathing configuration is very important here!
  13. Volume B is now marked primary and hosts continues to access the volume via the same WWN as before. Host IO will now be serviced on the active path to the secondary array without the host application even knowing what happened!


What you need

Here’s your list:

  • A WAN link between your two data centers should not have more than 2.6ms latency. This is important as remote copy synchronous needs to be able to send the write and wait for an acknowledgement within a given time frame.
  • One thing to note is that previously, vMotion used to be supported only on networks with round-trip (RTT) time latencies of up to 5 ms but with VMware vSphere 5 introduced a new latency-aware Metro vMotion feature that increases the round-trip latency limit for vMotion networks from 5 ms to 10ms.  The requirement for 5ms seems to be a thing of the past moving forward allowance cool things like spanned virtual data centres in this regard.
  • The ESXi hosts must be configured using 3PAR host Persona 11.
  • Host timeouts need to be less than 30 seconds. This time does not include the subsequent recover and reverse operations so leave some headroom.
  • The WWNs of the volumes being replicated have to be the same. Therefore, ALUA is also a requirement
  • From a 3PAR-licensing point of view, you need 3PAR remote copy synchronous, and Peer persistence of course which is licensed on a per array basis as well.


Peer persistence supportability

For now, HP 3PAR Peer persistence is only available for VMware clusters:  vSphere 5.x and up. More platforms to be supported in the future.













In Closing

So Peer Persistency is a HA solution that removes barriers traditionally found in physical data centers .  This is not the single entity defining a virtual data centres, but simply acting as just one of the pillars supporting it allowing virtualization and storage to not be constrained by physical elements anymore like in the past.  To this end, achieving a more aggressive BC plan is becoming more realistic.

Best Practices Data Migration HP Storage

Sometimes Data migration is inevitable. High costs and increased business risks don’t have to be.

Every major initiative for optimizing data center performance, decreasing TCO, increasing ROI, or maximizing productivity – including consolidation, virtualization, clouds, server upgrades, tiered storage, data analytics and BI tools – involves storage data migration.


Data has an incalculable value, and its loss can have significant impact. As Frost & Sullivan says in a recent Executive Brief, “one would expect that storage data migrations should be approached with the same attention a museum lavishes on a traveling Rembrandt exhibit.”   To expand on this, in 2012 it was estimated that $8 billion dollars worldwide was spent in data migration services.


A research white paper published in December 2011 entitled “Data Migration – 2011″ by Philip Howard from Bloor Research shows the average cost for a data migration project is $875,000, so to extrapolate the value and criticality on these types of projects should be fairly straightforward. Overrunning project budget, or rolling back a failed migration due to lack of planning,  are normal occurrences – in fact this same study proposes that the average cost of a project overrunning its budget is $268,000.00 – approximately 30% of the average cost of a data migration project.


Between 1999 and 2007, 84% of data migrations went over budget and overtime; this is astronomical and costly – and it can get very tricky when trying to pinpoint just why did the data migration project go over budget and over time. More often than not, it is usually down to lack of experience and planning (and I do believe that experience and planning should come in the same sentence.)


And there are potentially serious risks involved. Recent studies show that migration projects nearly always have unwanted surprises: 34% of migrations have data missed or loss,  a further 38% have some form of data corruption.


And probably the biggest risk associated with migrations is that 64% of migration projects have unexpected outage/downtime.  Now, tie this back to a research paper put forward by Vision Solutions in 2011, which shows that the typical cost of downtime can reach nearly 6.5 million dollars per hour for some in the Brokerage service industry, and up to 2.8 million dollars per hour for those in the Energy Industry.  To really understand this and put it in context, let’s have a look at some of the reasons why we migrate.


Why do we migrate data?

The migration of data isn’t typically something an IT manager or CIO does for fun, end of the day it will cost money and time. Ageing infrastructure or the need for a particular technology feature that’s not available on the current infrastructure are just a couple of the reasons why people migrate. In my experience, it’s all of the above. CIO’s are constantly (or should be) looking at new and innovative ways to reduce footprint and drive down environmental costs, such as data centre space and power, as well as expose newer and greater technological advancements within a given product set.  Newer product releases for infrastructure seldom take a step back when it comes to form factor and power draw.


So do customers who perform migrations achieve their overall goals? Not exactly…As I mentioned above, those undertaking DIY migrations typically have surprises which result in a heavier investment in staff to try and remediate those surprises, subsequently resulting in a project budget that is exceeded. Yes, 54% of the time a project budget is overrun due to these challenges but I’m not here to throw stats at you – I’m here to raise the awareness that if not properly planned and executed, your data migration project (as big or small as it may be) will run into at least one of these surprises.


HP Data Migration Services can help you address those challenges and risks. Each data migration project has astorage and data migration project manager assigned to make sure everything goes smoothly. We understand that storage infrastructures are typically multivendor, which is why our service is vendor-agnostic. We work to keep costs down and help you avoid the common pitfalls and risks of data migration.

To learn more about the new HP Data Migration Service, check out this online presentation. You’ll learn about the typical project flow and your migration technology options. Data migration is not usually just a simple copy-and-paste exercise.

3PAR HP Virtualization VMWare

VMware vVol and HP 3PAR

Last year,  Calvin Zito did a good overview on VMware Virtual Volumes or vVols.


This is game changing in my opinion, this essentially means the virtual machines will be able to leverage the 3PAR for ANY operation – when you throw an ASIC in the mix and our wide striping and you will have a solution that will simply leave the competition for dead in my opinion. Cloud Computing and time to market to provision or to complete day-to-day tasks will become unreal.

At the moment, this is still in development mode so I am limited to what I am allowed to share, but stay tuned folks – seriously this is going to rock.

NOTE:  This is a techology preview and doesn’t represent a commitment from VMware nor HP to deliver anything shown in this video

Recently, Calvin Zito , Craig Waters and myself jumped on a call to discuss a range of topics around VMware – more specifically Craig’s involvement in Melbourne VMUG and what the recently VMUG meeting in Melbourne had in store. We also discussed the upcoming VMware PEX which Calvin will be going along to.

Unfortunately, there is also a part which I am forced to discuss the All Blacks losing to the English – Was hoping Calvin would cut that part from the final reel!  🙂

Head over to Calvin’s site and have a listen!





So Cloud-Land appears to be getting smashed on the traffic plan it is on…… So………………………………..

EVA HP Storage Thin

HP EVA to HP 3PAR Online Import

What is it?

Now this is really cool, at a high level these new announcements now give you the risk free incentive to move your current workloads residing on an HP EVA P6000 to HP 3PAR and benefit from a leading storage platform.


HP EVA to HP 3PAR Import

So if you are currently running an existing HP EVA box and love the new HP 3PAR platform. I introduce to Online Import!


Online Import migrates volumes from a HP P6000 EVA to an HP 3PAR StoreServ system

Volumes are migrated online, minimally disruptive or offline depending on host OS, and best of all you can migrate full to thin volumes (and back again)


Online Import from EVA to 3PAR directly from EVA Command View:















Seamlessly move from your legacy HP EVA array to the new 3PAR architecture, and reek the benefits that it has to offer virtual environments including:


Thin Conversion

Go thin on the fly! The migration will be performed enabling the reclamation of 128MB regions using the hardware based Gen4 ASIC magic, allowing in-line, wire-speed “fat-to-thin” conversions compatible with any host volume.

Zero Detection.

Stay thin! As data is written to new 3PAR LUN, provided you have zero detect on your existing thick LUNs will shed the weight and become thin!

Note: There are still some operating systems that do not support the automatic reclamation of space using the T10 UNMAP command. Have a read on my VMware-related post on this notion here.

Storage Tiering – LUN and Sub-LUN (Block)

Automatic data-driven and policy-driven response to data placement. Simply put – busy workloads reside on faster disk to service the IO queue, and less busy reside on cheaper disk. Just simple!


There is a 180 day time based Peer motion shipped free, this license time starts at installation time, so if the license is enabled at the factory then it will start to tick down.

The license will generate appropriate alerts once the 180 days is drawing close.

Alternatively there is a permanent license too!


What is the difference between the existing Peer Motion and Online Import

The fundamental difference between these two offerings is based on the source array:

  • Peer Motion deals with HP 3PAR to HP 3PAR arrays only whereas
  • Online import deals with HP EVA to HP 3PAR arrays.


The other difference that one is disruptive (associated outage for cutover) and one is non-disruptive.  I still recommend VMware Storage vMotion over disruptive methods if time is not an issue for obvious reasons.


Supportability – EVA to 3PAR Import roadmap


So what’s the catch?

Of course with any migration, there are pre-requisites and requirements some are obvious and some are not.  The main pre-requisites are

  • Current version of OI supports only EVA x400 series running min firmware XCS09534000 to EOS/P7000


  • Destination array: HP 3PAR StoreServ 7000 or 10000 running HP 3PAR OS 3.1.2 (not 3.1.1!!)


  • So there is no Online Import license for F- and T-Class, meaning F- and T-Class cannot be target for Online Migration …. However we can use the Peer Motion license for F and T (associated costs).


  • vDisks that are larger than 16TB cannot be migrated (unsupported size on 3PAR presently)
  • All vDisks presented to a host are migrated (no subset selection possible…..yet)


  • No support for HPUX hosts and\or clusters


  • Does not support Linux or Solaris clusters (Windows and VMware ESXi clusters only)


  • Can only migrate one HP EVA and one host at a time


  • Access to a box with HP P6000 Command View 10.2 to facilitate the migration which also has FC connectivity to source P6000 EVA and has IP connectivity to destination HP 3PAR StoreServ system over TCP ports 5781 (3PAR Events) and 5783 (3PAR Secure CLI).


How do I get it?

Easy! Online Import is part of the “Typical” Install Set for HP P6000 Command View 10.2

3RD party array -> HP 3PAR

So what happens if you are running a 3rd Party Array and wish to transition to HP 3PAR?  No problem, get in touch with our storage consulting team who has a vast amount of experience in this solution.

Have a read of my HP MPX200 post to gain an insight on the method we use, fast, risk-free and best of all giving you the ability to go thin on conversion.

Cloud HP Storage Thin Virtualization VMWare

Introducing the new kids on the block… HP 3PAR StoreServ 7000












Today, at HP Discover in Frankfurt, we announced a new line of HP 3PAR storage systems boasting smarter architecture, higher storage capacity and greater performance for customers.

Built for converged infrastructure, cloud and virtual environments

Without being bias, I believe the HP 3PAR architecture holds a cutting edge story like no other. With full mesh architecture and the ability to scale as your virtual environment grows, 3PAR simply rocks. OK, that does make me sound like I have drunk the cool aid a tad, but a lot of customers like converged infrastructure models -that’s why 3PAR is in synch with our server stack and VMware technologies through management plugins.


Take a read why I think 3PAR architecture is a great platform for VMware environments and also read about our VirtualSystem offering in this space. And also Learn about other HP converged storage announcements in HP Discover in Frankfurt this week.


So without further ado, lets introduce these new kids:


HP 3PAR StoreServ 7200

The new HP 3PAR StoreServ 7200 series is the entry level 7000 series model in the family. This model offers a 2-node architecture, and up to 144 drives (SSD, SAS , NL) with a maximum capacity of 250TB raw. Perfect for the home offices of small to medium size businesses.

On the connectivity side of things, the HP 3PAR StoreServ 7200 offers up to 12 8GB FC ports and up to 4 x 10Gb ISCSI host ports with an additional 2 built-in ports dedicated for HP 3PAR remote copy replication use.

HP 3PAR StoreServ 7400

Need more grunt than the 7200 model? Enter the HP 3PAR StoreServ 7400 model. This model offers up to 4-node architecture with up to 480 drives (SSD, SAS, NL) for simply awesome tiering capability through the use of our Dynamic Optimisation and Adaptive Optimisation automated tiering functionality. With a maximum capacity of 864TB of raw space, this puppy won’t see you running out of space anytime soon.

For connectivity, the HP 3PAR StoreServ 7400 offers up to 24 8GB FC ports and up to 8 x 10Gb ISCSI host ports with an additional 4 built-in ports dedicated for HP 3PAR remote copy replication use.
Stay tuned for SPC-1 benchmark results on this model.


What is the difference between the two 7000 series models?

Technically speaking, the number of drives supported, maximum capacity and port counts are the major differences, with the 7400 model offering more than the 7200 model across all accounts.

Both support RAID levels 0, 1, 5 and 6 giving you the flexibility to choose, and not locking you into just one.

Take a look at the back of one.










The good thing to remember is that both models have support for our HP 3PAR software packages, which means that you can get the most out of your environment.


Still the same cool architecture and guarantees you’ve known from before…


System wide striping for greater performance – Everything touches everything, full mesh performance, write-cache mirroring, smart I/O processing for mixed workloads.

Gen4 ASIC for hardware based thinning – Good for those Eager-zero thick VMDKs and removing the excess “fat” from thick LUNs .

But wait there’s more, these bad boys also support HP 3PAR Dynamic and Adaptive Optimisation – policy-based autonomic LUN and sub-LUN meaning it will put your virtual machines on the right storage tier at the right time resulting in a cost-effective way to store your data.


Double VM density – guaranteed!

With the unique system wide striping, and support for mixed workloads (whether virtual or not), we can guarantee you twice the density of VM’s over legacy arrays. We have such tight support with VAAI primitives such as atomic test and set that we can offer HW-assisted locking on VMFS volumes as well as superior performance through Adaptive optimization.


Learn more about HP 3PAR Get Virtual Guarantee Program


50% less capacity – guaranteed

The key is in the magic sauce – GEN4 ASIC offering Silicon-level integration with VMware VAAI primitives such as Write Same for thin conversion/detection and Space Reclamation to keep virtual environments thin!

Support for VMware stuff?

Release of VMware vCenter Multi-Hypervisor Manager 1.0

What is it?

VMware vCenter Multi-Hypervisor Manager is a component that enables support for managing heterogeneous hypervisors when used in conjunction with VMware vCenter Server v5.1 and vSphere Client 5.1.

It is not available for the vSphere Web Client, with this in mind I am not sure what the roadmap for this will be post 5.1 seeing as they are EOL the desktop client.

Virtualization VMWare

run VMware View?? read this!!

Following the announcement of VMware vSphere 5.1, I came across this interesting KB article

In a nutshell:








This is important as VMware View runs on the vSphere platform, so if you are looking to upgrade the hypervisor to 5.1 then you may run into some support problems should you be running VMware View as well..  Dont sweat, sources tell me this is a temporary obstacle and will be cleared up in the near future, for now my advice is to hold off the upgrade or run separate clusters for your view environment if you absolutely need the vSphere 5.1 features sets.

My first VMworld 2012 – A wrap

VMworld 2012 was held in San Francisco, USA  in August this year.  This was to be my first (and hopefully not last) VMworld conference,  I have a lot of memorable moments from the whole trip – probably too many to list here but nonetheless it was a very memorable trip.  The flight over and back was full, not cool for a relatively tall fella like myself.

I met some brilliant minds in the industry, and got to go to my first NFL game ever (Thanks @vStewed!) as well as doing a podcast with a good colleague of mine Calvin Zito (@HPStorageGuy), you can listen to the podcast at this link.


Some of my favourite sessions:

STO1430: Tracking Down Storage Performance Issues: A Customer’s Perspective

Speaker Keith Aasen, NetApp, Scott Elliott, Christie Digital


STO2980: vSphere 5 Storage Best Practices @

Speakers: Chad Sakac, EMC Corporation, Vaughn Stewart, NetApp


VSP1800: vSphere Performance Best Practices

Speaker: Peter Boone, VMware


Over 300+ sessions available for download @


Now, onto some of the major new announcements that are worth a mention:


vRam goes vByeBye

Probably the biggest announcement made at VMworld 2012 was that VMWare has decided to drop the vRAM memory model that came out last year with vSphere 5.0.

This meant each edition of the vSphere tool had a virtual memory cap for each license, and if you needed more virtual memory for your ESXi host, you had to buy enough licenses to cover the total virtual memory in use by your VMs. Personally I wasn’t a big fan of it as I liked the simpler per socket approach as did a lot of VMware customers.


Monster VM’s now with more monster!!

The new release of ESXi has a bigger, faster, stronger CPU virtualization method, VMware refer to this method as ” virtualized hardware virtualization” or “VHV” for short, which  offers guest operating systems running inside of the VM “near native access to the physical CPU.”

New specs offered with this release of vSphere include 64 vCPU, up to 1TB RAM, 1 million IOPs out of a single VM.  All of this whilst still keeping the efficiencies we have all come to love with vSphere.


Shared Storage? Doesn’t matter!

Another important announcement is the capability to perform a virtual machine live migration between two separate physical servers  without the need of those physical hosts being attached to the same storage. Traditionally this requirement has been around since vMotion came out with ESX Server, but now VMware has redesigned it so that the memory state and files with the metadata describing a powered on VM can be transferred between hosts using their DAS.


No more desktop client…. 

vSphere 5.1 now comes with a new Web-based client that you can use instead of the Windows-based application that or the Linux-based virtualized console . This new web console snaps into vCloud Director, the cloud orchestration tool sold by VMware. Pity for IOS users as this new web client requires Adobe flash 🙁

I am curious as to how VCP certification will change given that the questions revolve heavily around the desktop client GUI.


Storage vMotion goes parallel!

Storage vMotion now supports up to four parallel disk copies per VM. Nuff said.

See What’s New in VMware vSphere 5.1 – Storage for more.


vCenter Single-Sign-On (SSO) 

vCenter Single Sign-on is a new feature in 5.1 that means you no longer log directly into vCenter Server but with a security domain defined in your vSphere environment.

Previous versions of vSphere meant you needed to log into vCenter Server directly, you were authenticated with the provided username and password against the Active Directory configured for vCenter Server

A point to note is that vCenter SSO is an additional component in the vSphere suite, but is required before any other vSphere 5.1 component (not ESXi) is installed or upgraded to 5.1.  The idea is that it will run as an additional service on top of vCenter service so there is no need to start re-architecting or working out the impact that it may have to your virtual environment


In closing.

VMworld 2012 was simply outstanding, the quality of the sessions and the solutions exchange were remarkable. You can find a link ,  I look forward to the next one I have the opportunity to go to and especially to meeting more people and catching up with in the industry we have come to love.

This is an excellent in any virtualisation processional’s toolkit.. A good friend of mine wrote the following about this poster here so I will quote from his post.

“The poster is a reference to all things related to vSphere Standard Switch (VSS), vSphere Distributed Switch (VDS), and Virtual Extensible Local Area Network (VXLAN) technology. It provides you information on the different components, terminologies and parameters of VSS, VDS, and VXLAN. It also explains the advanced features of VDS and discusses some best practices.”

VMware vSphere 5.1 released!


VMware vSphere 5.1 has finally been officially released.

For me, one of the biggest things I have looked forward to is the revamped vSphere web client,  which was announced at VMworld 2012 a few weeks back.


With the desktop version going away, the new web based client means that I (and other MacOSX users) can now enjoy the freedom of not spinning up a Windows virtual machine in order to get access

to the windows based desktop client.

HP Storage Virtualization VMWare

What is VM Density?

What is it?

VM Density used to be (and still is) referred to as the following three contextual definitions related to performance:

  • Number of VM’s that can run on a certain number of physical CPU’s
  • Number of VM’s or workloads running on a host
  • Number of VM’s or workloads running on a single datastore.

What is the business benefits for me?

Storage CapEx – In order to cater for a certain workload IO requirement you need the right mix of spindles to achieve that requirement.  Running more workloads on less spindles can decrease the initial CapEX spent and TCO is also reduced for a variety of reasons.

Server CapEx – By getting the best efficiency and optimal configuration allows the customer to run more VM’s on less physical servers.  So customers may not need to spend more CapEx buying extra servers, this provides particular benefits in TCO such as power, maintenance as well as licensing.

Licensing benefits – By having less hosts, customers generally spend less on host licensing.


So how do I optimise my VM density? Enter HP 3PAR

At HP, we introduced the HP 3PAR Get Virtual Guarantee earlier this year, which is a program to guarantee you will double your VM density from a IOPS perspective over your legacy solution if you shift to 3PAR.

So here is a hypothetical situation to explain the guarantee

If you are currently running an environment with workloads of say 30,000 IOPS (collectively), we guarantee we can provide an array that can handle at least 60,000 IOPS for those workloads.

Cool huh?

Small print – If you are running your virtual machines in an environment such as FusionIO or SSD’s then this guarantee will not apply.


Whats the secret sauce to this?

HP 3PAR Wide striping – Each physical drive within an HP 3PAR is broken up into chunklets which in turn is made up into RAID groups, so when data (VM’s in this example) is written, the blocks are striped to every single spindle in the array using these chunklets.  This approach aggregates the storage which of course pools the IOPS allowing better performance.

HP 3PAR has been designed from the ground up for virtual and cloud environments, with its VAAI, ASIC and thin provisioning capabilities contributing it really is one of best VMware integration stories on the market.

Refer back to my specific blog post on HP 3PAR Wide Striping here

Whats news in vSphere 5.1 – A dive in.

There has been a number of improvements made to the base hypervisor, probably notably around Auto Deploy.

For those who are not familiar with Auto Deploy who have not had a chance to play with it, what it essentially gives you is the power to rapidly deploy new vSphere hosts into your environment and bring them up to a specified patch level you define.  Putting this in a cloud-computing context and in particular infrastructure as service is a BIG step forward – This is becoming more and more automated,  time to market is a key metric when measuring how well your cloud computing business is running.

Without further ado, let’s dive into the new announcements.


vSphere 5.1 – Platform

The vSphere 5.1 has undergone a number of enhancements including:

  • Local ESXi shell users automatically get full shell access.  It is no longer required to share a single root account enhancing your audit-trail.
  • SNMPv3 is now supported bringing authentication and SSL support to the host-monitoring infrastructure.
  • Auto Deploy now offers a stateless caching mode that caches the boot image in order to permit a host to boot using the last good-known image should the Auto Deploy infrastructure be unavailable.  I see this as a potential turning point in the adoption of Auto Deploy.  There is a requirement for a dedicated boot device for this feature to function.
  • Auto Deploy can now be leveraged for stateful installs.  This may be beneficial to accounts that already have PXE in place but want to continue using traditional stateful methods.


vCenter 5.1

  • vCenter Server is the primary point of management for most environments and it too has been enhanced and tuned for this new release.  Some of the new additions include:
  • The vSphere Web Client is now the primary point of management.  It was noted during a session @ VMworld last week that the vSphere Client will no longer see development or receive new features.
  • An interesting new feature of the Web Client is the ability to pause a task and resume it from the “Work in Progress” task section.   This is helpful if you need to gather additional information to complete a task without cancelling it and starting over.
  • The Web Client does NOT need to be installed on the same server as vCenter Server and you can scale-out your vCenter services across servers.
  • Support for Open LDAP & NIS authentication using the Web Client (not the traditional vSphere client), this will make Linux-only environments happy.
  • Single Sign-on.  Read the PDF for more (the traditional vSphere Client is not supported).
  • The Web Client can track multiple vCenter Servers and inventory objects using the updated Inventory Service so you can now manage multiple vCenter environments from a single pane of glass without using linked-mode unless you wish to share permissions and licenses.


vSphere 5.1 – Performance

Outside of the obvious scalability improvements (64vCPU’s, 256 pCPU’s, >1M IOPS) vSphere has undergone a number of refinements in order to improve performance and management;

vSphere can now attempt to reduce the memory overhead of a VM by swapping out the overhead memory reservation of each VM to disk.  This can increase overall consolidation ratios and improve VM per host densities but it comes with the requirement that the swap file be manually created by the administrator to leverage this feature.

Use the following CLI command in your kickstart install or perform post-install.

esxcli sched swap system set -d true -n <datastore name>


If you have previously read and implemented the recommendations in the Best Practices for Performance Tuning of Latency-Sensitive Workloads in vSphere VMs technical white paper you will know that it can be a manual and administratively intensive process (outside of PowerCLI).  vSphere 5.1 now offers a checkbox to enable the VM .VMX settings for you saving a number of manual steps.


The traditional vMotion and storage vMotion (svMotion) have been combined into one operation offering the ability to perform a vMotion of a VM that does NOT leverage common shared storage.

This means that two servers using direct attached storage (DAS) can vMotion a VM between them.

Consider this feature beneficial for migration scenarios but there is a catch!  The svMotion operation occurs across the “Management Network” vmkernel interface.

So if you are using an HP BladeSystem/Virtual Connect infrastructure you may want to review your design if you have followed any of the Virtual Connect guides that say it is a “best practice” to use a 100Mbit Management FlexNIC.  A 1GE Management interface is recommended and what I recommend.


While on the svMotion topic; vSphere 5.1 has changed from performing serial disk migrations of VMDK’s within a VM to a parallel method if the VMDK’s reside on distinct datastores, so lets take a look at Storage stuff



vSphere 5.1 – Storage

Storage is commonly the least understood topic and receives the least exciting but most useful features.  I won’t cover the new disk format as it is primarily View related however there are other areas of improvement.


  • High Availability will now restart VM’s that encounter a Permanent Device Loss (PDL) state (5.0 U1 did too).  Please understand that a PDL is much less common than an All-Paths-Down (APD) state where HA does NOT respond but we may yet get there in the future.  HA responding to PDL’s is a step in the right direction.
  • 16Gb FC HBA’s are now supported.  Where vSphere 5.0 supported 16Gb HBA’s in 8Gb mode, vSphere 5.1 enables the full 16Gb throughput.  An interested tidbit confirmed by Emulex reps on the VMworld show floor indicated the leveraging a 16Gb HBA in 8Gb mode will outperform a similar 8Gb HBA due to the 16Gb HBA ASIC improvements in I/O processing.
  • SMART monitoring has also been introduce using esxcli  (but NOT vCenter) in order to examine disk error characteristics.  This has been targeted for SSD monitoring but it can only be leveraged using the command line.


  •  The ability to automatically detect and set the congestion threshold to the 90% percent throughput mark.  This is done using the SIOC injector that measure latency against throughput and can dynamically tune the threshold to the characteristics of the underlying disks.  It is very much a “set it and forget it” feature that dynamically adjusts to a changing environment.


  • Additionally, the underlying SIOC injector has also undergone improvement in where it measures the latency characteristics.  Instead of a leveraging the datastore latency metric which effectively ignores the storage stack above the datastore level, the new SIOC injector leverages a new value coined VmObservedLatency that measures higher up the virtualized storage stack as detected by the actual VM’s in order to more accurately reflect the performance characteristics experienced by the application or user.


  • The SIOC injector now also has the ability to detect common underlying disk striping configurations in order to avoid svMotioning VM’s across datastores backed by the same spindles on the back-end of the array.   The VMware vSphere Storage DRS Interoperability white paper includes recommendations when and when _not_ to enable I/O load-balancing in a SDRS cluster but obviously these recommendations were not always being followed.



vSphere 5.1 – Networking

Networking is another interesting topic and the vast majority of improvements are focused the vSphere Distributed Switch (vDS).  I should call out that if you are using Enterprise Plus licensing you should take a serious look at the vDS as the classic vSS (vSphere Standard Switch) is unlikely to evolve in the future effectively at its max feature potential.

  • Network Health Check (VLAN, MTU and failover team validation) is a very welcome addition as I have seen customer environments encounter HA events (and unplanned VM downtime) due to misconfigured teaming and/or switchports.  You want this feature!!


  • vDS Management network rollback and recovery is the catalyst that will calm the fears of a cluster-wide failure due to accidental misconfiguration of a fully vDS design.  If a change occurs and the management network loses connectivity the vDS will automatically rollback the last change(s).  A very impressive live-demo of this feature was shown at VMworld.  This is one of the last hurdles for what I see as the beginning of majority support for the vDS instead of the vSS.


  • vDS Distributed Port Auto Expand – while a nice touch in itself the PDF has some helpful information on selecting the best vDS “Port Binding” method for your environment.  The Static Binding method is the default and likely best candidate for the majority of environments out there.  Consider a traditional server has a fixed cabling configuration into a physical switch, the cables do not move.  This is akin to static binding, a fixed configuration that does not depend on vCenter to PowerOn VM’s.


  • Dynamic Binding is depreciated.


  • Ephemeral is a “plug-and-pray” method with no fixed binding but you therefore lose vCenter performance history and stats and increase the troubleshooting complexity.  Not recommended for most.
  • There are a number of other great features but I want to point out one last new feature that mitigates a risk that has been hiding under the radar across most environments.   The BPDU filter.  If your VMware environment is connected to a network that leverages the Spanning Tree Protocol (STP) then prior to vSphere 5.1 it is possible to take host VM networking offline if you follow VMware’s own switchport configuration guidelines.


  • VMware recommends that all hosts should NOT participate in STP by enabling PortFast and BPDU Guard that prevents accidental layer 2 bridging loops from causing a network disruption.  The problem is that a VM with two or more vNIC’s attached could potentially bridge interfaces and introduce a loop.  When this loop is introduced, BPDU packets are sent out and a properly configured switch would err-disable the port attached taking the VM offline and eventually all other vmnic’s attached to the switch by nature of VMware failover capabilities.  Consider this a denial of service risk.


  • Now with the vSphere v5.1 you can enable this advanced feature, Net.BlockGuestBPDU, which is disabled by default on both the vSS & vDS.  This is the only feature that I can see that has made its way into the vSS and I would highly recommend that any environment using STP and no intention to leverage VM-based bridging by design enable this setting.

Meeting Calvin Zito

I have “virtually” known Calvin for some time now having subscribed to and read his blog, I actually sent him a message just when I joined HP to say “G’day”, over the months we stayed in contact and organised to potentially meet at VMworld 2012 in San Francisco (depending on travel approvals). We organised to meet and finally I had the privilege of meeting Calvin at VMworld and recording a joint podcast with him that introduces me to his bloggers (Thanks Calvin!).  I also learnt that Calvin also lived in New Zealand once upon a time and also shared a love for the All Blacks!

HP Storage Thin VMWare

Building the business case to choose HP 3PAR – The Ninja’s way.

One of the cool things I get to do in the HP storage consulting business is show customers the potential savings they may profit from simply by moving across to an HP 3PAR storage array. This assessment nicknamed the Capacity Savings Assessment is backed by HP’s Get Thin Guarantee and can really show what the move to 3PAR can do for your business.

This assessment can help you evaluate your data utilisation rates and provide reports on capacity, power, cooling and even floor space savings.

This can introduce a range of benefits to your business such as smaller footprint, smaller electricity bill, less management overhead etc.


Here is what some pages from the sample report looks like:

So how does it do this? it scans the host’a filesystem and reports allocated vs used vs freespace.  To report accurate potential thin savings, the environment must not be thin provisioned already (no point in thinning out an already thin environment right!)

Current support host sets are Windows (any flavour), Unix, Linux and VMware vSphere 4/5.

Key reporting includes Capacity Utilisation, Disk Space Usage, Summary of the 3PAR configuration and a comparison of a 3PAR configuration with the current environment.

From a VMware perspective, the newest release no longer uses VMware PowerCLI  to obtain the information, instead it utilised vSphere’s native SDK and can scan NFS datastores.





To help justify a business case of what this means in $ value, consider the following page:

Now I ran this on my home lab, so the statistics aren’t staggering but I hope you get the point.

The aim here is to by going thin will mean less storage which can mean less power and less datacentre costs!  which of course can mean cost savings.

So onto the technical stuff.

What network ports does it use?

Windows: port 135 (RCP/DCOM)

Linux: port 22 (SSH)

ESX: port 443 (HTTPS)


How much network traffic will there be?

Network traffic resulting from a capacity scan is marginal. Testing shows less than 4KB per scanned host.


What permissions does it require?

Windows: User account must have Read Security and Remote Enable permissions on WMI namespace root\cimv2

Linux/Unix: User Account must be enabled for SSH login and have permission to run the df and lshal commands.

ESX server: User account must have vCenter browse privilege.


Will it add overhead?

No, the discovery tool is a lightweight tool, the execution overhead is marginal, typically less than 5% CPU utilization.

HP Storage Virtualization VMWare

HP 3PAR Management plugin for VMWare vCenter


What is it?

The HP 3PAR Management Software Plug-In for VMware vCenter is a vSphere vCenter management console plug-in that allows easy identification of HP 3PAR virtual volumes used by virtual machines and datastores.


What does it do?

It can provided a single pane view of the virtual machines and the 3PAR virtual volumes resources they are attached to.  It can show capacity, usage, thin and thick properties on a volume basis and also the disk type the virtual volumes are made up of.  The beauty of this plugin is that you do not need to login to the inform console to view the virtual volumes mapped to your ESXi hosts. Note: It does not allow you to provision\manipulate the storage from this GUI – Inform Management console is still required for that!


A peek at the interface


This screenshot really does say it all, you can see how much savings you are getting with using the 3PAR thin suite functionality, you can also see the name of the virtual volume that the VMFS is housed on making it easier for administrators to locate and map virtual machines, trouble shoot and provide reports.

And of course, it shows you whether or not you are getting the most out of your EZT VMDKs, by showing the status of the Zero Detection engine on the array ensuring your 3PAR stays thin!

And best of all, the plugin is free!

T10 UNMAP in VMware vSphere and 3PAR

What is T10 UNMAP?

UNMAP is a SCSI command used to reclaim space from blocks that have been deleted by a virtual machine (OS or application).

In vSphere 5, UNMAP is used for space reclamation of deleted data after common operations

This is particularly beneficial and important in thinly provisioned environments as it allows the storage array to realise these are unwanted or unused blocks and to return them to the free capacity pool.


What makes UNMAP important?

HP 3PAR thrives on the thin suite and it supports UNMAP as of Inform OS 3.1.1, however the first release of vSphere 5.0 had some issues where there were unexpected timeouts when the UNMAP command was issued from the ESXi host during an operation.

So when an operation like storage v-motion or a virtual machine is deleted, a copy or movement of data is kicked off essentially leaving behind deleted blocks, HP 3PAR can only realise this so long as UNMAP is started to reclaim those blocks. Since administrators are using storage v-motion on a day-to-day basis, the impact can be huge.


So what do you do?

Disable it until VMware release a fix – expected in the next patch release.

Use a manual command such as sdelete on Windows or dd on Linux to write zeros at the file system level, The 3PAR’s ASICs will pick these zeros up so long as zero detect is enabled.


How can UNMAP be disabled?

Support for UNMAP in our storage arrays is enabled by default and cannot be disabled by customers. In vSphere support for UNMAP is enabled by default but can be disabled via the command line interface.

esxcfg-advcfg –s 1 /VMFS3/EnableBlockDelete


This can be completed automatically by installing ESXi 5.0 Patch 02. For more information, see VMware ESXi 5.0 Patch Image Profile ESXi-5.0.0-20111204001-standard (2009330).



  • This issue only affects thin provisioned arrays in the 3PAR family
  • UNMAP is a SCSI command standardized within T10 SCSI command set – It is not specifically a vSphere 5 feature
  • This Issue only occurs when using ESXi 5.0 and 3PAR arrays that have the latest firmware.
  • Customers can still reclaim space without UNMAP using the 3PAR arrays zero detect functionality should they disable UNMAP
  • A patch is available that resolves this issue

An interesting view from two years ago…


Data growth – IDC believes that the Digital Universe will grow by 44 times that of 2009 by 2020. IBM estimates that data and content is growing at a compound annual growth rate of 64% a year or more. (Zettabyte = 1 trillion gigabytes).”

Gartners Magic Quadrant – “Magic Quadrant for Midrange and High-End Modular Disk Arrays.”


Gartner is an independent provider of IT and research advice, Gartner’s latest Magic Quadrant for Midrange and High-End Modular Disk Arrays assesses storage vendors on their “ability to execute” and “completeness of vision.”  Placing the candidates into one of the four quadrants each representing different definitions.

So what does this mean?

  • Leaders execute well against their current vision and are well positioned for tomorrow.
  • Visionaries understand where the market is going or have a vision for changing market rules, but do not yet execute well.
  • Niche Players focus successfully on a small segment, or are unfocused and do not out-innovate or outperform others.
  • Challengers execute well today or may dominate a large segment, but do not demonstrate an understanding of market direction.

And to be selected, the vendor must meet the following criteria:

  • The vendor must have midrange and high-end modular disk array storage systems commercially available and have active references that are using them in production scenarios.
  • The vendor must generate at least $25 million in annual midrange and high-end modular disk array hardware revenue.
  • The vendor must actively market its branded midrange and high-end modular disk array products in at least two major regions (for example, North America and EMEA, or Japan and Asia/Pacific).
  • The vendor must sell its branded midrange and high-end modular disk array products to user organizations via its direct sales force or through a reseller partnership sales channel.


From an HP perspective –  Gartner included the following HP Storage solutions:

  • HP 3PAR
  • HP LeftHand
  • HP Enterprise Virtual Array (EVA)

So let’s dissect this and see what changes have occurred since the last period.

Certainly, there has been massive movement shown in this graph , EMC and NetApp’s gap closed slightly and HP’s ability to execute position increased dramtically as did its position in the visionaries quadrant, this is no doubt due to the acquiring, development and rise of it’s 3PAR platform.
There hasnt been much movement from HDS, Dell seems to have taken a sideways step in some ways, IBM remains static since the last period. Its hard to really say who really leads in this view,  NetApp and EMC are  “Leaders” and are performing or executing really efficiently  however HP are also leaders and appear to have a better understanding of the market and where it is going.















I look forward to the 2012 version of this research release, it surely shows there is a healthy competitive environment for this area of technology. Well done to the leading four storage Vendors – EMC, NetApp, HP and IBM.

vBenchmark – A Quick look

What is vBenchmark?

vBenchmark is a tool from VMware and is a simple to use tool that measures VMware virtual environments looking into how much physical RAM you are saving by virtualising your servers, provision time for a server, what is HA, storage v-motion, v-motion doing for you from a downtime savings perspective.

It can obtain performance metrics across one or multiple vCenter servers


What can it do for me?

It can give you a view of what going virtual as a business decision is doing for you, it is good for justifying the decision to move to a virtualised environment – cost savings on hardware is the first and most prominent benefit that virtualisation can offer not to mention the green factor. vBenchmark gives you figures\statistics from a resources and business perspective.


 What does it look like?

I set vBenchmark up on my laptop as a virtual machine to take a look at the interface. Whilst my laptop isn’t the most performance system around, it did give me ability to gain an overview of the tool.


The Console


The web interface

Where can I get it from


Overall, a very useful tool provided you have historical data in your VCDB to populate it.  It works brilliantly and can assist in trending\future proofing your virtual environment.

HP Storageworks MPX200 Migration.

So being part of the extended HP APJ Storage Consulting team, I wanted to share my thoughts on a preferred way to migrate between 3rd Party arrays and HP.

Having worked with the leading storage vendors in the world, I have seen many methods of migration during my delivery days.  There are obviously industry best practices to which customers typically tend to go for as directed and guided by the storage vendor, but then there are customers who prefer to do it themselves (usually utilising host based methods over array based methods).  There are obvious caveats of this,  host based migration tends to be a lot slower and places loads on the host handling the migration.
There there is SAN based migration, where a customer would have to usually purchase some form of license that gets enabled on the storage array itself,  this tends to be expensive (unless you get a very generous Sales Manager that lends a customer a license for the duration of the migration).

Enter, HP Storageworks MPX200 appliance for migration services.

What is it?

The HP Storageworks MPX200 appliance is a purpose built device that can assist in Database/Storage/Application migration from one storage array to another.

Best of all, it has heterogeneious array data migration capability!


  • The MPX200 can have both 1GbE and 10GbE iSCSI connectivity, as well as 4/8Gbps FC, FCIP for SAN over WAN.
  • MPX200 includes remote online/offline data migration for support between two data centres and asynchronous replication.
  • Disaster recovery (DR) capabilities
  • Online/Offline migrations. There are some points to note around this though.
  • Schedule migration jobs.
  • Supported on heretogenous FC storage arrays – NetApp, EMC, Hitachi, IBM and of course HP.
  • Fully supported with Brocade and Cisco FC fabrics – this is because the architecture is built on QLogic FC HBA technology.

Use-Case Scenarios

When to use to migration to HP 3PAR

  • Heterogeneous Migrations
  • Consistent way to reclaim unused blocks across all major OSs, Space reclamation tools will prepare dirty blocks for Thin Provision

When to use to migration to HP XP

  • Convert Thick Luns to Thin Provisioned Luns using Space reclamation tools and MPX200 capability
  • Heterogeneous Migrations
  • User wants to cut over from old to new after migration is successfully complete

When to use to migration to HP EVA

  • Convert Thick Luns to Thin Provisioned Luns using Space reclamation tools and MPX200 capability
  • Heterogeneous Migrations

When to use to migration to HP P4000

  • Migrate FC storage to P4000 ONLINE/OFFLINE
  • Convert Thick luns to Thin provisioned luns


This is the cool part, you can migrate data online/offline at 4TB/HR with a  single blade and 8TB/HR full chassis between heterogeneous storage arrays using a user friendly data migration GUI.

Offline Migrations

  • No downtime required to plan & configure, Migrations up to 4TB/Hr
  • Server with less than 1TB storage can be migrated in 1 Hr. application downtime
  • Reduces implementation time – saves money
Online Migrations
  • Insert MPX200 into the Data path without application down time during migration
  • Downtime only when cutting over to new storage
  • Keeping Source data “Current” through out the migration process – User can always fall back

Of course I leave this bit for last, it is really straight forwards and different licenses for different cases.

Capacity or Per-TB Licenses

  • “Fills the petrol tank”. Unused capacity will be available for next job
  • Can be installed at anytime, adding new license doesn’t overwrite remaining license capacity

Per-Array Licenses

  • Unlimited Data migration for a specific array
  • Many sources to one target
  • One source to many targets

Supported topology One

Supported topology Two 

Example topology for best performance

MPX200 patches into the same fibre channel switch as the source and destination array.
