Virtualization VMWare

Vsphere 5.0 and the new licensing scheme

OK so how license worked in vSphere 4 was straightforward: licenses were bought on a per CPU socket and you could run unlimited virtual machines (VMs) on the host until it crashed and burned (if you desired).

Things have changed in vSphere 5.0, whilst still working on a per socket basis, licenses also now come with a set amount of virtual RAM or vRam that can be allocated to VMs.

This could result in a customer to spend additional unnecessary dollars in additional licenses to be compliant with new vSphere 5 licensing scheme. If the customer buys hosts that can hold a large amount of RAM, these licenses costs can start to prove very costly.

To quote VMWare from their white paper on the matter.

"VMware vSphere 5 is licensed on a per-processor basis with a
vRAM entitlement. Each VMware vSphere 5 processor license
comes with an entitlement to a certain amount of vRAM capacity,
or memory configured to virtual machines. Unlike in vSphere 4.x
where core and physical RAM entitlements are tied to a server
and cannot be shared among multiple hosts, the vRAM entitlements
of vSphere 5 licenses are pooled, i.e. aggregated, across all vSphere
servers managed by a vCenter Server instance or multiple vCenter
Servers instances in Linked Mode"

HP Personal Uncategorized Virtualization


My name is Andre Carpenter, I am a IT technologist from New Zealand working as a Consulting Solutions Architect at HP working in the Data Centre Transformation, Virtualisation and Cloud presales team based in Melbourne Australia. I also work with the APJ wider storage consulting practice just to spice things up.

My focus within the region of APJ/ANZ for the team is enterprise storage (3PAR), cloud offerings and virtualisation. I use the term “virtualisation” loosely as I rarely find myself dealing with the likes of Hyper-V and Xen, but more in the VMWare space and in particular server virtualisation.

I set up this blog to try and capture some of the interesting pieces of virtualisation and storage work as well as personal (and professional) interests and learnings I engage myself in on a day-to-day basis, for the most part these all revolve around Storage, Cloud computing and VMWare. The topics I write about will no doubt be written for myself to gain a better understanding or to share my experiences on topics I am confortable with – Sometimes I tend to choose subjects that I am not always very familiar with, write about them and share my findings, so hopefully you may gain something from them.

Although I work for HP, please understand that the views and expressions I share on this site may not necessarily reflect HP’s view of the IT world and that they are entirely my own.
