This card works much differently than, say, the HighPoint and Promise ATA RAID cards you can get. It has a i960 controller on the card and basically reports itself as a SCSI controller to the OS. They are nice cards, I set up a FreeBSD box with one of these and four 80GB IBM GXP drives not tool ong ago. -- coleman On Thu, Apr 18, 2002 at 06:18:22PM -0500, Albert Chin wrote: > On Wed, Apr 17, 2002 at 04:14:01AM -0500, Mark Nipper wrote: > > On Wed, Apr 17, 2002 at 10:57:28AM +0300, Vallo Kallaste wrote: > > > We're considering Adaptec 2400A's for new server.
