Environment:
- Storage: HP P2000 MSA G3 SAS Array with 24 300GB 10k SAS Disks
- Two Storage Controllers with redundant SAS connections to each host
- Hosts: Three HP DL380 G7s with a 10GB SD Card, CPU, Ram, etc...
ESXi 5.0 is installed on the SD card in each host, this is the only local storage on each host. I have the P2000 split into two vDisks, each using 12 of the 24 disks. Call them LUN1 and LUN2. Each LUN is its own RAID6 volume.
I spoke with HP support over the phone about layering RAID1 over my two RAID6 arrays. This is not possible, so I'm trying to figure out what the best way might be to implement mirroring. I was looking at OpenFiler and FreeNAS, but honestly don't know how those solutions would work in a mission critical application.
