As you no doubt heard by now, VMware has announced a new version of vSphere along with some new or improved features however, this post will not highlight these features. In this post, I want to talk about what did not improve – the licensing.
With the announcement of the VMware vSphere 5, the biggest thing that startles me is the way that VMware has found to a way to collect more revenue from users with new server technologies. This seems to be totally going against the flow of x86 market since the main message of the major server manufacturers (in the past) has been how they can save users $$ on VMware licensing by offering the ability to stack your servers full of memory.
For example – take a look at the IBM HX5 blade server combined with the MAX 5 which provides users with a total of 40 memory DIMM slots and a current maximum of 640GB using only two processors. Taking a look at the comparison, with the previous vSphere 4.x licensing, you would only need two VMware vSphere 4.x Enterprise Plus licenses. (With 640GB of RAM, one can only imagine how many virtual machines were possible with just 2 licenses.)
Since more users were moving to at the architecture of larger 2 socket systems with A LOT of memory, I believe that VMware realized the vSphere licensing opportunities were than they expected so they decided to change their licensing method to a “per CPU and memory” licensing model creating the concept of a processor and vRAM pooling of entitlements.
Here is a look at a comparison of vSphere 4.x licensing vs the vSphere 5 model:
So, if we use the example of a the IBM HX5 blade with MAX5 mentioned above maxed out with 640GB of memory with the NEW licensing model a user would need 14 VMware vSphere 5 Enterprise Plus Licenses to be “legal” vs 2 with the current VMware vSphere 4.x licensing model.
According to VMware, the good news is that there is “no limit to the number of cores per processor”, but in reality – I don’t see that that as a big deal. vSphere 4.X already supported 12 cores per processor with vSphere Enterprise Plus licenses which is the maximum of the current market – even the next generation Intel 2 socket CPU will only be 8 cores – so there is no advantage to changing the licensing. This is why many people are calling this new licensing model “vRAM Tax“.
We all agree that VMware has the best products and is the market leader for virtualization, BUT this new licensing model is giving ammo to Microsoft and Citrix to strike at the cost issue (which was already an issue in VS 4.x).
