Configuration notes:
Low profile SAS RAID controllers and HBAs for external storage are supported in the low profile and
full-high PCIe slots supplied by the x8 or x16 riser card.
The total quantity of the RAID 930-8i, 16i, and 8e controllers in the server must not exceed 1 (up to 1
supercapacitor can be mounted in the server).
The following table summarizes features of supported RAID controllers and HBAs for external storage.
