BTW, like most of Adaptec's other controllers the 7211[CF] is effectively Windows-only, and the QLogic controller is very likely too new to work with most platforms Cyrus runs on. It's not that the QLogic card won't ever work with (say) FreeBSD, it's that FreeBSD's driver's most likely aren't up-to-date enough to work with the card at this point. Without one of those cards iSCSI is a CPU hog. Sadly, a second CPU (or an upgrade to dual-core CPU) is cheaper... -- Phil Brutsche phil@xxxxxxxxxxxxxxx ---- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
