We run a microsoft hyperv 2012 environement.
We have the following storage volumes setup
- Volume1 (Raid 5) running on an IBM V3700 SAN
- Volume2 (Raid 5) running on an IBM V3700 SAN Expansion
- Volume3 (Raid 10) running on an IBM V3700 SAN Expansion2 (Not currently in use due to RAID10 testing)
Volumes 1 and 2 are setup as one cluster on which we run all our virtual machines off.
We run the following 2012 virtual servers on SAN cluster1 which consits of SAN volume1 and volume2:
File server , Exchange server, DC, various application servers and 2x SQL servers
I'd like to know from the experts if is best practice to group certains servers togerther per volume to ensure we gian maximum performance from the SAN and virtual machines.
