We received a HP P2000 LFF SAS today with 8 450GB 15k SAS drives, it will hold a max of 12. There will be 2 VM hosts (HP DL380 G7) conncted to it via SAS. There will be 4-6 VMs running initially with plans to use this for VDI at some point. We will be running Exchange and SQL on the VMs along with some other applications. We will be running VMWare Vsphere 5.
What RAID option should we go with with 8 drives? I was thinking RAID 5 with 6 or 7 drives and the remaining drives setup as hot spares.
Thanks!
