1: Introduction
Cooling System
The SGI Rackable C2108-TY11 server chassis has an innovative cooling design that includes
three 8-cm hot-plug system cooling fans located in the middle section of the chassis. An air shroud
channels the airflow from the system fans to efficiently cool the processor area of the system. The
power supply module also includes a cooling fan.
Serverboard Features
At the heart of the SGI Rackable C2108-TY11 system is a dual-processor serverboard based on
the Intel 5520 + ICH10R chipset and designed to provide maximum performance. This section
describes the main features of the serverboard. See Figure 1-2.
Processors
The serverboard supports single or dual Intel Xeon 5600/5500 processors.
Memory
The serverboard has eighteen DIMM slots that can support up to 288 GB of 1333/1066/800
registered DDR3 ECC SDRAM (see “Installing Memory” on page 34).
SATA Controller
A SATA controller is integrated into the ICH10R (South Bridge) portion of the chipset to provide
a six-port 3 Gb/s SATA subsystem with RAID 0, 1, 10 , 5 and 6 supported. The disk drives are
hot-swappable units.
Note: The disk drives are hot-swappable units if your operating systems has RAID support.
PCI Expansion Slots
The dual-processor serverboard has four low-profile PCIe 2.0 x8 slots, two low-profile PCIe 2.0
x16 slots, and one low-profile PCIe 2.0 x4 slot (see “PCI Expansion Slots” on page 50)
