Be careful. Ideally, the controller should be  supported  by  drivers
that  are included withthe standard kernel.org Linux tree. If this is
not the case,  try  to  find  out  if  you  get  Linux  drivers  with
*complete*  source  code. Both Highpoint (RocketRAID) and Adaptec are
known to include binary-only modules in their drivers, even  if  they
seem  to provide source code. This is always a PITA and may seriously
mimit your on specific *usually very old) kernel versions.

I returned such a card because I could not get it working with the
kernel versions I wanted to run.

On the other hand, the Supermicro card worked fine for me out of the
box.
