We are doing a base install of ESX 3 on a Dell dual quad-core PowerEdge 2950 with 6 - 400 Gig SAS drives. I am expecting to have a variety of different machines that I might run from this physical machine. I am curious what reccomendations for RAID arrays the group might recommend. I'm concerned with maxmizing performance while providing redundancy. I considered 3 RAID 1 Mirrors and then I could isolate to different RAID sets / physical disks without incurring the write penalty for the pariy information of RAID 5.
Thanks,
Charles
