System Module (SMOD)
This section contains information about the server system module (SMOD) and its components:
SMOD Overview
The SMOD contains:
-
Externally-accessible:
-
Server storage drives (HDD/SSD)
-
IO ports and two external USB ports
-
-
Interally accessible:
-
Internal host bus adapter (HBA) card
-
SMOD motherboard
-
Two internal USB ports
-
System battery
-
The SMOD is accessible and removable from the back of the server. The two removal and installation levers are located on the sides of the SMOD and have two green lock release tabs. The following illustration shows the location of the SMOD at the back of the server and the two release levers:

Storage Drives
In the following illustration, call out 1 shows the location of the eight storage drive slots, which are on the SMOD and arranged in two rows of four each.
For component serviceability, locations, and designations, see About System Components.
SMOD Motherboard
The SMOD motherboard hosts the service processor (SP), two disk backplanes (for the externally accessible server storage drives), and the system battery. It also has a PCIe riser for the server storage HBA and two internal USB ports. The PCIe riser and the two internal USB ports are located on the bottom of the SMOD.
For component serviceability, locations, and designations, see About System Components.
Service Processor (SP)
The system Pilot 3 service processor (SP) is located on the SMOD motherboard and is accessible locally and remotely through management ports on the front of the SMOD. The SP contains a version of Oracle ILOM, an embedded server management tool that can be updated using Oracle System Assistant. The SP is not removable.
Storage Drive Backplanes
The externally accessible server storage drives on the SMOD connect to two backplanes mounted on the SMOD motherboard. A SAS cable also connects the backplane to the HBA card that is installed in a riser slot on the bottom of the SMOD. The backplanes are not removable or replaceable.
For component serviceability, locations, and designations, see About System Components.
SAS Host Bus Adapter (HBA) Card, Riser, and Cables
The server requires one internal HBA for the externally-accessible SAS (or SATA) SMOD server storage drives. The HBA is installed in a riser slot on the underside of the SMOD motherboard and is connected to the backplanes by two mini-SAS4I connector cables.
The following illustration shows the HBA card installed on the underside (bottom) of the SMOD and the two SAS cables that connect the HBA to the server storage backplanes.

Internal USB Ports
The SMOD also has two internal USB ports on the underside of the SMOD motherboard next to the PCIe card riser slot. The ports are designated as P0 and P1.
Unless you have opted out, port P0 has a factory-installed flash drive that contains Oracle System Assistant, a boot-capable server set-up, provisioning, and update tool. Port P0 can only be used to support Oracle System Assistant. It cannot be used to boot an OS or store files unrelated to Oracle System Assistant.
