Re: amd64 dualcore nad raid1
I use that exact board with the same setup. The RAID1 on it is not true RAID, so I use the Linux Software RAID to set up two RAID1 arrays of 2 drives each (i need two separate physical arrays for my purposes). It works well, and performance is good. Debian Sarge with the 2.6 kernel detects all hardware nicely. I recommend that setup. - Naz Francesco Pietra wrote: i intend to setup a workstation for quantum mechanical calculations (organic chemistry) with a couple of amd64 dualcore 265 and a couple of STA hard disks 360GB raid 1 (mirroring for security reasons). Do you think that mainboard Tyan Thunder S2877ANDF x 2 Dual Opteron under debian testing/unstable provides adequate raid 1 support without going to expensive 3ware products?

Re: amd64 dualcore nad raid1
Apologies, I use a slightly different board, the one on the Tyan Transport Server Chassis GT24. Its the same chipset though, so you can pretty safely assume Sarge will have the same support for it. - Naz. Naz Gassiep wrote: I use that exact board with the same setup.

Basically, I have found: - If you pay less than about US$1000 for your card, you are getting fakeraid (that is, software RAID implemented in firmware) - With disks being so cheap today, you are hard pressed to justify using anything other than RAID1 - The software RAID in the kernel is much more uniform, in that you can manage disparate hardware in exactly the same way -Roberto -- Roberto C.
