Some months ago I wrote a lot of post about Hyper-V vs VMware vSphere. At this time I compared Windows Server 2012 Hyper-V Release Candidate with VMware vSphere 5.0. Since then a lot has changed Microsoft released the final version of Windows Server 2012 and VMware showed vSphere 5.1. I don’t have time to update every post I made but this should cover an overview about the numbers in both versions. This is mostly only about scale and a lot of customers will not hit any limit in both products, but still I think it is interesting to see how they compare.
There are a lot of other important arguments to use one or the other product, but I won’t cover this in this blog post. The data is from the Microsoft paper: Competitive_Advantages_of_Windows_Server_2012_Hyper-V_over_VMware_vSphere_5.1.pdf. In this PDF you can find more information about the advantages of Windows Server 2012 Hyper-V.

Hi Thomas,
i can’t download the pdf file from the link. :-(
The table 2 says “Yes” for ESX5.1 supporting virtual fibre channel, however, i am not able to find any reference to virtual fibrechannel in any of the website for vmware. can you please provide me a link.
