Fairly new to FreeNas, so I will try and make this short.
I have a Dell PE 2950 and MD 1000 disk array with 15 - 300GB drives. I'm currently running ESXi 5 with a FreeNas VM. The perc 5e controller doesn't support pass through SCSI in ESXi so I'm stuck doing something creative.
My question is should I slice up the drives using the perc controller, and do a couple raid 5 volumes in order to add into ESXi as datastores then add disk into Freenas as seperate volumes to do raid-z (better protection?), or should I just create a bunch of raid 0 volumes for each disk in the perc controller and then let Freenas manage each VMDK disk?
Please note that I can't do pass through so each disk that I'm assigning to FreeNas VM would be VMDK disk from a datastore. I was reading something online about doing RDM's inside of ESXi for each volume that I would create in raid 0, not sure how I feel about that.
Example: Currently testing with this setup, created 5 volumes on the perc controller with 5 disk running raid 0. Inside of ESXi I have 5 datastores, I added 5 SCSI disk to the FreeNas VM and then I did raid-z inside of FreeNas to create one volume. Seems to work, but I'm not sure how a failed drive will react inside of FreeNas using this setup.
I guess I'm looking for the best way to set this up to protect from a failure. Performance isn't really a factor since this is just a NAS that will store backups, photos, video, etc...
Thanks in Advanced.
