I guess that depends on how we interpret "mirroring". Mirrored boot disks make sense and are required in a traditional environment such as OmniOS. SmartOS just needs a method of getting the server up and running. SmartOS can be booted from a USB stick; CD ROM; or iPXE boot - effectively two fallback methods in addition to your primary boot method. ZFS has use of all the disks - internal or otherwise - for data storage. Depending on their size I'd recommend 3-way mirrors to ensure redundancy in the event of a disk failure and long resilver times. I'm not against OmniOS - we run it here and love it! The only negative I can see running SmartOS is the lack of IPS packaging - but it's a minor negative at that. -- Mark
