We have Sun STK RAID cards in our x4170 servers. These are battery backed with 256mb cache. What is the recommended ZFS configuration for these cards?
Right now, I have created a one-to-one logical volume to disk mapping on the RAID card (one disk == one volume on RAID card). Then, I mirror them using ZFS. No hardware mirror. What I am a little confused with is if it is better to not do any logical volumes on the RAID card and only use ZFS mirrors for creating the pools. Please see configuration output here: http://pastebin.ca/1971460 Also, what exactly does "write-back" mean?
