Massive iSCSI IOPs for Hyper-V

Suzanne Morgan, a Senior Program Manager – Storage and File Systems at Microsoft is presenting a webcast today at 11 PST on some fantastic iSCSI performance numbers (Check out this blog for information on the webcast).

I don’t want to steal all the thunder from this webcast, but would like to share with you some exciting information. The webcast talks about both Windows Server 2008 R2 iSCSI performance numbers, but also Windows Server 2008 R2 Hyper-V performance numbers.


What this graphic shows is that with Hyper-V using Intel VMDq and Microsoft VMQ, we are achieving 750,000+ IOPs, and achieve native throughput at 8k and above block sizes.

What does this mean? Well, if you are going to run, say, Microsoft Exchange in a VM hosted on iSCSI storage, you will be able to handle a tremendous amount of mailboxes even under a “heavy” profile.


Take a listen to the webcast and see where Windows Server 2008 R2 has gotten to.
