The server I/O storage subsystem consists of the following:
The server contains 11 PCIe Gen 3 slots, of which nine are x8 slots and two are x16 slots. All 11 slots are available in a four-CPU configured server. Only the first six slots (1-6) are available in a two-CPU configured server. Slot 2 is reserved for the HBA to drive the six storage drive slots. For slot designation information, see PCIe Slot Designations.
For information about the processor subsystem, see Processor Subsystem.
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:
Sun Storage 6 Gb SAS PCIe RAID Internal HBA (SGX-SAS6-R-INT-Z)
Sun Storage 6 Gb SAS PCIe Internal HBA (SGX-SAS6-INT-Z)
For slot designations, see DVD, Storage Drive, and USB Designations.
An optional DVD-RW SATA-Gen2 drive. The DVD drive is located at the front of the server below the drive bays.
For DVD designation, see DVD, Storage Drive, and USB Designations.
The two internal USB ports are located on the motherboard between the disk drive backplane and the PSU backplane boards. The ports can take a standard USB flash device, which can be used for system booting. Your system might be equipped with a preinstalled Oracle System Assistant USB device. Do not use the Oracle System Assistant USB drive for booting an OS or as server storage. If installed in your server, the Oracle System Assistant USB drive must be installed in the internal port labeled "OSA USB" and it must contain only the Oracle System Assistant file system.
For port designations, see DVD, Storage Drive, and USB Designations.
Additionally, the server has four external USB ports, two on the front panel and two on the back panel. See External Components and Features.
