I was doing some blog-surfing the other day and came across Christian Saborio’s virtualization blog. He mentions this really cool tool published by Microsoft that helps IT directors figure out costs of virtual machine licenses in different editions of Windows Server 2003 R2: Standard, Enterprise and Datacenter.
From Christian’s blog:
Riddle me this: How many licenses of Windows Server Enterprise Edition would you need if you are planning on running 20 Virtual machines inside a server that has 2 processors? Very, easy, you would need only 5 licenses. Too tough? How about this one…what would be the price difference if you were running 50 machines running Windows Server 2003 on a virtualization server with 2 processors if you chose to run the host machine with Windows Server Enterprise Edition vs. Windows Server Datacenter Edition? Very easy…running Datacenter edition would be $25,580 cheaper.
Of course, he didn’t make those calculations off-hand! Check out the nifty Windows virtualization calculator here.
