People seem to be doing OK if the RAID card is their Perc/6i, which has an LSI Logic MegaRAID SAS 1078 chipset under the hood. There's some helpful benchmark results and follow-up meesages related to one of those at http://archives.postgresql.org/message-id/47D8B3B6.3010606@emolecules.com That said, I consider the rebranded LSI cards a pain and hate the quality of Dell's hardware. Seems like everybody I talk to lately is buying HP's DL380 instead of Dells for this level of Linux installs nowadays, I haven't gotten one of those HP boxes myself yet to comment. -- * Greg Smith gsmith@gregsmith.com http://www.gregsmith.com Baltimore, MD
