Anyone have any experience with these products yet? We've got one in for eval, but I thought I'd also ask for experiences here... Thanks in advance. Dave Thompson The University of Wisconsin - Madison Computer Sciences Department

I've got two arrays on it right now, one raid1 and one raid0, both running very happily. The default centos 3ware drivers don't work with it yet. I'm not sure if this changes in update 3 (due soon) or not. Rebuilding the 3ware drivers for centos are trivial, and 3ware is hosting community provided driver disks and such on their site. Basically for the money, I'm quite happy with it. -- "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety'' Benjamin Franklin 1775

I've so far tried, among other things, raid0, raid5, lvm stripe over devices, heavy I/O while rebuilding, .. everything but two performance problems looks fine (#1 ext3 sucks on 3ware raid5, #2 I can't get good read performance on two raid5s in a lvm stripe). /Peter> > Thanks in advance. > > Dave Thompson-- ------------------------------------------------------------ Peter Kjellstr?m | National Supercomputer Centre | Sweden | http://www.nsc.liu.se -------------- next part -------------- A non-text attachment was scrubbed...

Got a 9550SX 4 port on a Tyan K8WE. Updated drivers, updated firmware and bios - nothing helped. Whenever I had high IO loads the system would crash. Eventually disabling write cache reduced the IO enough for the system to be stable. Peter.
