Modular system chassis

AC model is 10U high, up to four supported in a 42U rack.

DC model is 11U high, up to three supported in a 42U rack.

Both models provide the following:

• 10 vertical slots (front) for installation of server and storage modules

• Hot-swappable power supplies (AC has two. DC has four)

• CMM (rear)

• 20 vertical slots (rear) for PCI EMs

• 2 horizontal slots (rear) for NEMs

• 8 hot-swappable fan modules (rear)

• System status indicators (front and rear)

• Midplane (internal) that interconnects components through industry-standard PCIe, SAS, SATA, and Ethernet protocols

2

PCI EMs

Up to 20 supported in the chassis. PCI EMs are based on the PCI Express industry-standard form factor and offer I/O features such as Gigabit Ethernet, Fibre Channel, and InfiniBand (supported I/O features differ, based on the server modules installed).

Each server module can be associated with up to 2 PCI EMs.

3

NEMs

Up to 2 supported in the chassis. Each NEM connects to all 10 server and storage module slots. NEMs provide 10/100/1000 Ethernet, SAS connectivity to storage modules, and 10GbE Ethernet ports.

4

Chassis management module (CMM)

A service processor for monitoring and managing components in the chassis. The CMM is preinstalled with Oracle ILOM software.

5

Power receptacles

• AC model – 4 power receptacles with power cord retention clips.

• DC model – Blank panel.

6

Fan modules

6 redundant fan modules installed in the rear of the chassis.

7

Midplane

Inside the chassis, the midplane interconnects all the modular system components. The midplane supports industry-standard protocols such as PCIe, SAS, SATA, and Gigabit Ethernet.

8

Storage modules

Provide additional storage capacity to the modular system. The total number of supported storage modules depends on the model purchased. Refer to the storage module documentation for details.

9

Server modules

Up to 10 supported in the chassis. Server modules provide the following:

• Motherboard with an UltraSPARC or Intel processor, and industry standard FB-DIMMs

• SP that runs the Oracle ILOM software

• Hard drives

• Support for the addition of REMs

• Support for the addition of FEMs that are needed when certain NEMs are installed in the chassis

Each server module is independent, so both SPARC and Intel server modules can be installed, each having its own operating system (Oracle Solaris OS, Linux, based on what is supported for the server module).

10

Power supply modules

• AC model – 2 installed in the front of the chassis with power receptacles in the rear. Each power supply module has an integrated, replaceable fan module.

• DC model – 4 installed in the front of the chassis with power connections at the rear. Each power supply module has an integrated, non-replaceable fan module.

11

DC input unit

(Only on DC models) Provides the DC input terminals by which the DC input power cables are connected and includes Telco Alarm LEDs at the front of the chassis.

n/s

REMs

Provide HBA functionality on some blade servers. A REM mounts to a REM connector on the server module motherboard. Different RAID levels are supported, based on the REM purchased.

n/s

FEMs

Installed on the server module, FEMs enable server modules to use the 10GbE connections provided by certain NEMs. NEMs and the corresponding FEMs operate as a matched set.

n/s

Status LEDs

Located on the front and rear of the chassis. These indicators provide a visual status of the modular system through status OK, fault, temperature failure, and locate LEDs.
