If you are relying on virtual disks for recovery well that's an entirely different animal which I'd rather not get into. thanks From: [email protected] To: [email protected] Subject: RE: [Exchange] Log Files & DB on HyperV Date: Sat, 9 May 2015 15:42:43 -0400 I rely on backups for recovery, not on volumes/arrays/hardware , my concern is performance.

Virtualization changes nothing within the underlying rational for separating volume concerns on “physically different arrays”.

With that said you should be able to throw all the exchange files (database and logs) on the same volume as long as you are obtaining the IOPS required from the Exchange calc. Since IO has been reduced so much I don't think that should be an issue.

Back in the physical days , it was always OS, LogFiles, and DB on separate disks/volumes/arrays etc.. Now with virtulization, is it still recommended /best practice to create separate VHD's for the OS/DB/Log files for performance gain? TIA
