I would recommend against this; it's a "checkbox" option to satisfy people that haven't done the math yet comparing ATA+RAID10 with SCSI+RAID5 in 3ware's market segment. > Mike, have you got that tested with FreeBSD yet? I have not; I don't believe they're ready to release yet, and since leaving BSDi I am no longer bound by NDA to 3ware, I can't really ask for it. > They told me it would be a free downloadable upgrade to all 6X00 cards. I understand this is the case; since the CPU on the card is a 25MHz 16-bit part, don't expect performance to be startling unless they pull of something amazing with the FPGAs. > I asked them for the monitoring utility and the (most likely clueless rep) > said that development of that utility had been transfered to the FreeBSD > project. Is that the case? No; it's still being developed in-house. It's available for download from my RAID page (http://people.freebsd.org/~msmith/RAID/index.html#3ware) though. -- ... every activity meets with opposition, everyone who acts has his rivals and unfortunately opponents also.
