There doesn't seem to be anything inherently wrong with it :-) > 2) Does anyone have experiance with the 2540? Kinda. I worked on adding MPxIO support to the mpt driver so we could support the SAS version of this unit - the ST2530. What sort of experience are you after? I'ver never used one of these boxes in production - only ever for benchmarking and bugfixing :-) I think Robert Milkowski might have one or two of them, however. > 3) I've read that it's best practice to create the RAID set utilizing > Hardware RAID utilities vice using ZFS raidz. Any wisdom on this? You've got a whacking great cache in the ST2540, so you might as well make use of it. Once you've got more questions after reading the Best Practices guide (http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide) post a followup to this thread. You _will_ have questions. You will, I just know it! :-) cheers, James C.
