You most definitely should use COMSTAR to provision your iSCSI targets. It's a kernel based implementation and runs almost twice the speed of iscsitgt. To layout your disks I think RaidZ2 is a good choice for archive, I would use 4 groups of 7 and 2 groups of 8 this would leave 2 boot drives and 2 spares. You do not want very large groups as it increases the possibility of a total array failure event. Remember the rule of thumb " its not if your disks fails","its when your disks fails". Regards, Mike Thank-you.

I love your blog and thank you for it. I am currently getting ready to release for testing an OpenSolaris SNV 131 system for backup and VMWare, all provisioned as ZFS backed iSCSI. Would you advise using the traditional iSCSI methodology or the COMSTAR method outlined here? Mike – thanks for another impressive article. I love your blog and thank you for it.
