We have a HP MSA P2000 G3 SAS. Will be using it to host ESX VMDK files
12 - 1 Tb drives

Looking for best practice.
Option 1: 1 vDisk with a RAID 5 (11TB) or RAID 6 (10 TB) , then create 2TB Volumes
Option 2: 2 vDisk with RAID 5 (5 TB each) then create my volumes.
Option 3: What would you suggest

Not sure which will give me the best performance, was looking for ideas.
All ideas are appreciated.

12 disks is too many for RAID 5, the likelihood of a second failure during the slow rebuild process is too great. RAID 6 or RAID 50 would give better protection but both are slow on writes. I'd go for RAID 10 as that;s the best performing, especially as you've got relatively slow disks.

Nice to see someone using the SAS attached flavour rather than iSCSI or fibre channel.

RAID5s certainly won't give you best performance, if that's what you're after. Concur with "andyalder"...go with RAID10, then make sure you keep your LUNs under 2TB (2TB-512MB) for your datastores.

So I should leave it as one big vdisk raid 10 then create my volumes? I am going to test this before I put it into production, but if I lost a drive everything should run fine while its rebuilding?

Well, you don't need to...you can create 2 RAID10s, but you lose 4 disks of storage, so either 1 RAID10 or 2. Just depends on your storage needs vs performance needs which route you're able/willing to take. Yes, if you lose a drive (or 2), everything should run while rebuilding on new disks.

Two vdisks would be better than one, that way the controllers own one each assuming you're not gambling with a single controller model.

Thanks, guess I will test Raid 5 and 10 to see if there is a big difference in speed.
