The DPT PCI RAID card is only one that supports booting, but an external RAID box is easily twice as fast as an DPT card. - No online configuration yet. Each controller brand needs it own management app ported to FreeBSD. An external card usually has a nice LCD display. I can even hookup new drives and configure a new logical disk, or expand an existing logical disk with a couple of button presses (at least on Infortrend). As far standalone controllers, I'd go with an Infortrend over CRD. > -- > \\ Give a man a fish, and you feed him for a day. \\ Mike Smith > \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org > \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com Tom To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
