I've got a bunch of mission-critical Postgres servers on
Opterons, all with no less than 4GB RAM, running Linux +
XFS, and most with LSI MegaRAID cards. We've never had a
single system crash or failure on our postgres servers,
and some of them are well-used and with uptimes in excess

It may be anecdotal, but LSI MegaRAID cards generally seem to work
pretty well with Linux. The only problem I've ever seen was a BIOS
problem between the LSI and the motherboard, which was solved by
flashing the BIOS on the motherboard with the latest version (it was
grossly out of date

I have a similar question about what to choose (either LSI or Adaptec U320), but
plan to use them just for JBOD drivers. I expect to be using either net or
freebsd. The system CPU will be Opteron. My impression is that both the ahd

Thanks, Andrew. I expect to choose between HBAs with no RAID functionality or
with the option to completely bypass RAID functionality--meaning that I'll
hopefully avoid the situation that you've described. I'm mostly curious as to
whether the driver problems described for U320 Adaptec RAID
