this is the information I was hoping for ;-) sounds good.

both systems are running CentOS5 with a recent 64bit kernel, so this
shouldn't be a problem.

ordered one on ebay yesterday, really looking forward to receiving it
:)

this second-hand server was originally equipped with an U320 scsi
backplane which I removed. by this the hotswap capability is lost,
the drives will be directly connected to the AOC-SAT2-MV8 controller,
I can live with that. nonetheless it would be nice to have a SATA
backplane, but by googling I couldn't find one that fits into this
chassis (blue/white AVANTEK).
tnx.
