Running Exchange on Hyper V?

Microsoft will be publishing a support statement with respect to Exchange Server on
Hyper-V within 60 days of today.

…In terms of best practices and requirements, the following guidance was released:

  • We’re only supporting guests running Exchange Server 2007 SP1 on Windows Server 2008.
  • We’re only supporting fixed disks, and not dynamic disks.
  • Storage should be on spindles that are separate from the Guest  operating system VHD physical storage.
  • Storage must be SCSI passthrough or iSCSI (with a preference of SCSI passthrough for queues, databases and log files).
  • All Exchange server roles, except for the Unified Messaging server role, will be supported.
  • There’s a limit on VHD size of 2040 GB.

It was also mentioned that Hyper-V is a good fit when Exchange servers in branch offices cannot be consolidated to a central datacenter (for example, because of bandwidth or connectivity issues).

…So what’s the really great thing about this soon-to-be-released guidance?

60 days from now is just in time for Tech.Ed Australia and New Zealand!!!

Some of the more noteworthy bits of info from the session are:

  • Within 60 days of Hyper-V’s RTM, the Exchange team will publish a detailed support statement for Hyper-V, and a TechNet article with best practices.
  • Customers should not deploy Exchange on Hyper-V until our support guidance is available.
  • Early results show that performance of Exchange 2007 on Hyper-V is quite good, and that it scales very well from 1-4 processors per VM.
