Hi all, I am a complete newbie to OpenSolaris and am considering using OpenSolaris to build a commodity-hardware storage cluster. The proposed architecture is:
- N Storage servers running linux and presenting their disks to the storage controllers (see next) via iscsi; - M Storage controllers in a Sun Cluster; - all machines (servers and controllers) with 2 NICs, the first connected to an ethernet switch and the second connected to a different ethernet switch; - Using ZFS with RAID-Z to build a storage pool from the storage servers on the cluster with network raid N+1; I would like to know: - if this plan seems feasible (and not too complex); - how to use multipath on OpenSolaris so I can round-robin traffic along the iscsi paths to the storage servers; - how to use the 2 NICs on the controllers to ensure the cluster will not go down in the event of a switch failure. I have built a similar storage cluster in Linux with DRBD/GFS instead of ZFS but this will not scale to give network N+1 raid. Thanks in advance for any help. Kind regards, Mike
