Oracle^® Server X5-8 Service Manual

System Module (SMOD) Overview

This section provides information about the server system module (SMOD) and its components. It includes:

• SMOD Overview

• Storage Drives

• SMOD Motherboard

• Service Processor (SP)

• Storage Drive Backplanes

• SAS Host Bus Adapter (HBA) Card, Riser, and Cables

• Internal USB Ports

• Energy Storage Module and Cable

SMOD Overview

The SMOD components include:

• Externally-accessible:

  • Server storage drives (HDD/SSD)

  • IO ports and two external USB ports

• Internally accessible:

  • SMOD motherboard

  • Service processor (SP)

  • Storage drive backplane

  • SAS host bus adaptor (HBA)

  • Internal USB ports (2)

  • Energy storage module (ESM)

  • Real time clock battery

The SMOD is located at the back of the server. It includes two removal and installation levers with green lock release tabs.

The following illustration shows the SMOD 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 arranged in two rows of four each.

For component information, see About System Components.

SMOD Motherboard

The SMOD motherboard hosts the service processor (SP), two disk backplanes (for the externally accessible server storage drives), the system real time clock battery, and an energy storage module for the HBA. It also has a PCIe riser for the server storage HBA, and two internal USB ports. The PCIe riser and the internal USB ports are located on the bottom of the SMOD.

For component information, see About System Components.

Service Processor (SP)

The system Emulex 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 Oracle ILOM, an embedded server management tool. 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 information, see About System Components.

SAS Host Bus Adapter (HBA) Card, Riser, and Cables

The server requires one internal HBA (Oracle Storage 12 Gb/s RAID HBA, Internal) 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, the two SAS cables that connect the HBA to the server storage backplanes, and the cable that connects the energy storage module to the HBA.

For component information, see About System Components.

Internal USB Ports

The SMOD 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 bootable 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.

Energy Storage Module and Cable

The Energy Storage Module (ESM) provides backup power for the HBA. It sits in a holder in the top center of the SMOD, and has a cable that connects it to the HBA.
