3/5/2008 - Vmotion of Large Exchange VMs -- Comments
I saw this blog entry on savagenomands that wondered about VMotion with large Exchange VMs:
I actually did some similar testing with 2000 user Exchange VMs and measured the time for VMotion to complete as well as its impact on the users. The answer - about 6 and half minutes to VMotion a 2000 user VM while under stress (At least with the setup that I had. Your mileage will vary depending on your exact configuration). See the whitepaper on the VMware and Exchange page to get the complete details.

"Even with all that horse power, they didn’t talk about network traffic running all exchange 2007 roles on the same box. I wonder how long one of these boxes takes to vmotion. Also I’d like to know the details on how they setup the luns and if they used vmdk files "
