I have Exchange 2010 server running under HyperV with mailbox sitting on a DAS (C drive). For quite a while I've been extending the VM's hard drive to cope with the demand for space but I will soon run out of space on the host server so I'm wanting to move database and keep it on SAN connected through iSCSI.
Mailbox database is used by 160 users and just now its 100GB.
I'm thinking about setting up SAN storage unit - 8bay QNAP or anything similar and setting up two LUNs (one for mailbox and one for logs).
Can anyone suggest the approach or the hardware ? I'm not sure what to set up on the SAN - RAID5 or RAID10.
Any comments welcome.
