I currently have 8x320GB drives on a PERC 5e. I'm running them in RAID 50, so a little under 2 TB in usable space. This works out fine for the ESXi VMFS volume size limit (2 TB - 512B).
I just ordered enough Spinpoint F3 1 TB's to rebuild the array. My main motivation is performance, the move from RAID 50 to RAID 10 should help things. The extra space would be a nice benefit. Unfortunately a combination of ESX + PERC limitations will keep me from utilizing the full space of these drives. Those limitations being:
1) 2 TB - 512B VMFS volume limit (ESXi)
2) One VMFS volume per LUN (ESXi)
3) One virtual disk per RAID 10 set (PERC 5)
I don't see an easy way around this while still getting the full performance benefits of having this many drives. I'm OK sacrificing the space and making a 1.99 TB volume (effectively short stroking the drives), but if I could come up with a way to use all the space it certainly wouldn't hurt my feelings.
So this leads me to looking for a reasonably inexpensive hardware RAID controller that will do multiple virtual disks on a RAID 10 set.
Any ideas? Any easy ways around these limits that I'm missing?
