The server storage subsystem consists of the following:
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 storage controller installed at the factory. SAS drives require a SAS Host Bus Adapter (HBA) and NVMe drives require a PCIe NVMe Switch card.
When configured with SAS drives (mechanical or SSD), the system must have one Oracle Storage 12 Gb/s SAS RAID PCIe HBA, Internal (7110117) installed in PCIe slot 2. The PCIe Gen-3 internal HBA has eight internal SAS3 ports that connect from the card to the system backplane through two bundled cables.
When configured with NVMe SSD drives (up to four), the system must have one Oracle PCIe NVMe Switch card (7111393) installed in PCIe slot 1. The NVMe switch card has four NVMe internal ports that connect from the card to the system disk backplane through four bundled cables.
For slot designations, see DVD, Storage Drive, and USB Designations.
An optional DVD-RW SATA-Gen3 drive is located at the front of the server below the drive bays. A SATA3 port on the motherboard connects to the disk backplane through a SATA cable bundled with the HBA SAS1 cable.
