Hi, I''m attempting to build a ZFS SAN with iSCSI+IPMP transport. I have two ZFS nodes that access iSCSI disks on the storage network and then the ZFS nodes share ZVOLs via iSCSI to my front-end Linux boxes. My throughput from one Linux box is about 170+MB/s with nv59 (earlier builds were about 60MB/s), so I am pleased with the performance so far. My next step is to configure HA-ZFS for failover between the two ZFS nodes. Does Sun Cluster 3.2 work with SXCE? If so, are there any caveats for my situation? Has anyone been successful in developing a HA-ZFS environment without SC? I''d rather not go this route if possible, but if s10u4 release is too far off I may have to give this a go. Related question: anyone know when s10u4 is slated for release? June? Thanks in advance, --Dave

June?Hi David, SunCluster isn''t certified to work with Solaris Express or Solaris Express Community Edition. It *might* work, but you''re definitely on your own with it. I recommend against trying to implement your own HA environment without the protection of a cluster framework. I''ve seen too many people try to do that and fail miserably or catastrophically in the attempt. Save yourself the pain :) Re s10u4 release, I can''t comment on when it''s going to be released, sorry. James C. McPherson -- Solaris kernel software engineer Sun Microsystems
