Six 2.5-inch Drive Bays
The six 2.5-inch storage drive bays are located at the front of the server. The supported drive
interfaces for each bay depend on the type of host bus adapter (HBA) installed in the server.
When configured with any 2.5-inch SAS drives, the system must have one PCI Express (PCIe)
Gen-2 internal HBA card installed in slot 2 to support the front 2.5-inch drive bays. Each PCIe
Gen-2 HBA has 8 SAS2/SATA2 internal ports accessible through two SAS4I connectors (Port
0-3 and Port 4-7). Since the drive cage has only six bays, Port 6-7 of an internal HBA are not
used.
Supported SAS2 slot 2 HBA cards:
