Last August I wrote a blog post giving a general comparison of Hyper-V 2012 and vSphere 5.0. I’m speaking this week at the Virtualization Deep Dive 2013 conference in Cambridge, MA, so I thought I would like to dig in a bit to study the nitty-gritty feature enhancements and comparisons again, especially between Hyper-V 2012 and VMware 5.1 editions. I decided to take a look at HV 2012, vSphere 5.0 Enterprise Plus, the current free edition of VMware’s hypervisor and their “Cadillac” Enterprise Plus licensed edition. It seems that VMware has invested to catch up in certain key areas such as resources per guest and cluster size. Also note that the backup API set (VADP) is now included in the standard edition of vSphere, a feature which formerly was only included in the Enterprise and Enterprise Plus licenses.
It sure seems that Hyper-V, while still playing catch-up in market share to VMware, is making a really good play for a great portion of the hypervisor space. The price is certainly right, and helps the smaller shops out there take their first steps into virtualization with a feature-rich host platform.
Here’s the original chart, updated with free 5.1 and Enterprise Plus 5.1:
|Feature||Windows Server 2012 Hyper-V||VMware vSphere 5.0 Enterprise Plus||Free ESXi 5.1||VMware vSphere 5.1 Enterprise Plus|
