Promise SX6000 vs Adaptec 2400A

[Kian_Chang_Low at vdgc.com.sg]

Hi all,

With 3ware existing the IDE raid storage card market, I was looking for a
replacement for a cluster and came across the Promise Supertrak SX6000 and
Adaptec ATA RAID 2400A.

I have no experience with the above and hope someone might shed some light.

1) Which card has the better support for Linux? I had heard that Promise is
not very Linux-friendly and tend to lock the user to older kernel. Is that
true?

2) Does anyone has experience putting more than 1 Promise card on a system?
Is it possible?

3) Is there any other alternatives?

Thanks,
Kian Chang.
