Sadly I run 2 x 2 RAID1 disks, Do you mean you have two mirrors in a raid-0, or just two separate mirrors? If it's just two separate mirrors, linux kernel can deal with it. I haven't
Thanks for the tip. I'm definitely seeing 3WARE as the option of choice.

so I use all 4 Promise ports. I'll either have to revert to RH 2.4 kernel, as it supports the Promise, If you want to go to go 2.4, give SUSE 9.0 Pro a go. It's very stable (the .0 is misleading as it's really the most mature version of the 2.4 based, with very little changing between 8.2 and 9.0.).
If you know of a drive board, or RAID board that does work, I'd love to hear about it! 3ware! The 3ware cards have been discussed to death on the SUSE list. They're awesome products, supported under linux, and everything is fully hardware implemented. Quote from their site: "The 3ware 9500S hardware RAID controllers deliver in excess of 400 Mbytes per second (MB/sec) sustained RAID 5 reads and over 100 MB/sec RAID 5 sequential writes with less than 3% CPU utilization (Tested using Intel's Iometer(R) benchmark program on a dual processor Intel(R) Xeon (2.4GHz)"
They're pricey, but you won't be sorry -- Kind regards Hans du Plooy SagacIT (Pty) Ltd hansdp at sagacit dot com
