In Nov 2009 Cindy responded to a thread concerning ZFS device issues, cfgadm, and mpxio: http://mail.opensolaris.org/pipermail/zfs-discuss/2009-November/033496.html I''ve got an x2270 with the Sun EZ-SAS HBA and external SATA JBODs (not J4xxx). The external disks simply provide bulk storage; lousy performance is not a concern, reliability is. For obscure reasons, we''re going to destroy / re-create those pools. We originally skipped mpxio due to the cfgadm issues, even though we''d have preferred to have the reliablit...

We are looking at adding to our storage. We would like ~20TB-30 TB. we have ~ 200 nodes (1100 cores) to feed data to using nfs, and we are looking for high reliability, good performance (up to at least 350 MBytes /second over 10 GigE connection) and large capacity. For the X45xx (aka thumper) capacity and performanance seem to be there (we have 3 now) However, for system upgrades , maintenance
