HD Controller and upgrade

[Chris Caldwell]

I have a Howard NX1400 server with a Supermicro mother board (X6DHR-TG).
On that mother board is an Adaptec AIC-8130 Marvell 88SS6041 SATA
controller that we use for RAID 1 mirror.  The OS is Redhat AS v4 32bit
x86.  We would like to upgrade the current Redhat, but am stuck in v4
with the Kernel locked at 2.6.9-22.ELsmp because the driver is not
supported.  

Supermicro says buy a new HD controller if I want to upgrade, but they
do not know which.  

 

How does a newbie figure out which  controller card to buy so that I can
get up to date?

 

Chris.
