Compatibility of Riser cards and PCIe adapters
• Gen 3 riser cards can only support Gen 3 RAID adapters.
• Gen 4 riser adapters can support both Gen 3 and Gen 4 RAID adapters.
• Gen 3 and Gen 4 RAID adapters of the same group can be installed to the same riser card.
• Gen 3 and Gen 4 RAID adapters of the different groups cannot be installed to the same riser card.
• RAID adapters and HBA adapters can be installed to the same riser card.
• RAID arrays are not support for AIC(all-in-card) SSD drives.
• RAID arrays are not support for SED or FIPS HDD/SSD drives.
Note: FIPS (Federal Information Processing Standard) 140-2 is a U.S. government standard that
describes the encryption and related security requirements for sensitive but unclassified (SBU) information
technology (IT) products. FIPS 140-2 defines four levels of security, SEDs(Self-Encrypting Drives) are FIPS
140-2 Level 2 validated drives.
• When one or more SED drives are installed, the following internal SAS HBA adapters are not supported:
– 430-8i
– 430-16i
– 440-16i
• One super capacitor module is required for each 930/940 series internal RAID or 940-8e RAID/HBA
adapter.
