I've had good luck with a ATTO SAS PCIe HBA using with a tape
library. The driver for this particular card wasn't included
with CentOS at the time but might be with the latest version.


The drivers are open source, I have no past experience with
ATTO it was recommended to me by a tape backup software vendor
for their performance and stability under linux.

I am using the
"ExpressSAS H644
  Low-Profile 4-Internal/4-External Port 6Gb/s SAS/SATA
  PCIe 2.0 Host Adapter"
