* The onboard SATA controller integrated into the Intel C246 Platform Controller Hub (PCH) supports non-RAID (JBOD) AHCI mode
or a hardware-assist, software RAID feature (Intel Rapid Storage Technology Enterprise [RSTe]).
Configuration notes:
The onboard SATA controller does not consume a PCIe slot.
SAS RAID controllers and HBAs for internal storage are supported in the following PCIe slots:
PCIe slot 2 on the PCIe x8/x8 Riser Card (feature code B418):
No additional PCIe adapters are installed
One additional PCIe adapter is installed in the server in the PCIe slot 1
PCIe slot 4 on the system board:
Two additional PCIe adapters are installed in the server in the PCIe slots 1 and 2
A GPU adapter is installed in the server in the PCIe slot 2
The PCIe x16 Riser Card (feature code B417) is installed in the server
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 1610-4P NVMe Switch Adapter is supported in the PCIe slot 2 supplied by the PCIe x8 or x16 riser
card.
The 1610-4P NVMe Switch Adapter provides two PCIe 3.0 x4 ports for JBOD (non-RAID) connectivity
to U.2 NVMe PCIe SSDs in the drive bays 8 and 9.
The following table summarizes features of supported SAS/SATA storage controllers.
