New ZFS user here. NexSAN Satabeast with 42 500G Sata drives of course, Dual Channel 4G Fiber. Fibre network attached to Solaris 10 running on HP Blade. Possibly will add second solaris blade for failover.
Now I am looking for reliability with decent disk space totals. I would prefer not to lose 50% of the space to redundancy. This will be used for a ZFS NFS server with 100+ clients attached doing mostly reads, but some writes. It appears this devices does not have the ability to expose raw disks to the OS. Instead you have Raid Groups. Then you create volumes from those RAID Groups that can be exposed to the OS. There I was thinking of the following 8 Hardware RAID-5 Groups ( 5 drives each) and 2 SAN hot spares. zraid of these 8 Raid Groups. ~ 14TB usable. I did read in a FAQ that doing double redundancy is not recommended since parity would have to be calculated twice. I was wondering what the alternatives are here. Not doing ZFS redundancy means I lose the checksum abilities. Is that a good trade off instead of doing the double redundancy?
