They have very cheap RAID 1 mirroring cards as well as more expensive RAID5. We use the RAID1 cards, and have many motherboards with the Promise RAID built right in, and have had great success. We can hot swap the units now with the atacontrol command to dettach drives and then rebuild in the background without ever having to take a system down. A better way to go is with Escalade series cards. More expensive, but up to 8 separate channels of RAID5. The software solution for RAID on FreeBSD is called vinum - its in the ports tree I think, and there are how-tos that can be found via Google. Its free, but I would definitely recommend using hardware based RAID from the point of view of being able to manage it easier. Good luck, - Mike On 10/31/02 3:36 PM, "Feng Li" wrote: > > > Hello, Friends > > > > I have some FreeBSD machines, I need to improve their reliability. > Is there any Hard disk Mirroring feature(such as RAID 1, RAID 0+1,etc) > in FreeBSD system ?
