This is anecdotal, but I would say that the LSI1068 cards and the SASX28/SASX36 expander chips were far more prone to issues. I'm not saying it can't or doesn't happen on LSI2008/SAS2X28-36 - I had a prod box the other day that hard-hung because a Constellation went south, had to have someone go yank the disk - but it sure seems to happen a lot less with the newer kit and Phase10+ firmware. Got all sorts of mixes of SAS+SATA in large qty, mostly pretty stable. Even having a single SASX28/36 expander in the mix seems to add to the problems somewhat, for reasons that are not entirely clear. I have a couple around still. Hell, I have one box that is nothing _but_ 1068s and old 846E1s - 4 of 'em to be exact, 86 old 1TB cuda.12 drives - which pretty much just works. Granted it doesn't work that hard; it's archival material - but it runs and rarely errors. Still Sol10U9 even. *throws up hands* -bacon _______________________________________________ zfs-discuss mailing list email@example.com http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
