> I do not know Adaptec one, but I know 3ware has something similar. > We asked them for an evaluation board (retail is about $270) and come with > linux driver source. It works quite well under linux. It can be configured > as 2x2 stripe, 1x4 stripe (RAID1), and mirror (RAID0). The 2x2 stripe can > have 32MBps I/O rate which is not bad at all. > Four 45GB WDC IDE drives are $1000, plus a $270 IDE controller, you can > get total 180GB with 32MBps I/O at $1300 which is half price of the same > configuration for SCSI. Note that this controller doesn't support RAID 5 or hotswap. > The driver code is about 16K, but requires many linux header files. > I do not have time to poke Linux syuff at this moment. If some one is > interested in it, driver source can be download from www.3ware.com. I have one in the lab, and am working on a driver. It's next in the queue behind the ICP Vortex cards at the moment. -- \\ 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 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
