Chapter 1
1. Introduction
The SGI Rackable C2112-4GP3 server is a 2U rackmount server (see Figure 1-1).It has two main
subsystems: the 2U server chassis and four nodes with dual-processor serverboards.
Figure 1-1 The SGI Rackable C2112-4GP3 Server
This chapter describes the server using the following topics:
•“Server Chassis Features” on page 2
•“Serverboard Features” on page 4
•“Additional Hardware Components” on page 7
•“Special System Notes” on page 8

1: Introduction
Server Chassis Features
Table 1-1 describes the main features of the SGI Rackable C2112-4GP3 server chassis.
Table 1-1 Server Chassis Features
Feature Description
System power The chassis includes a high-efficiency 80-plus Platinum certified power
supply, rated at 2000 Watts plus one redundant backup power supply. In the
unlikely event your power supply fails, replacement is simple and can be
accomplished without tools.
SATA subsystem The chassis supports up to 12 hot-swappable 3.5” SATA drives in trays (3
for each node). These drives are hot-swappable units and are connected to a
backplane that provides power and control.
Note: The operating system you use must have RAID support to enable the
hot-swap capability of the drives.
Front control panel The chassis includes four front control panels on the handles of the chassis.
Each control panel provides you withsystem monitoring and control for one
server node. LEDs indicate system power, HDD activity, network activity,
system overheat, and power supply failure. A main power button is also
included on each control panel.
I/O ports The chassis is a proprietary-form-factor chassis designed to be used in a 2U
rackmount configuration. The chassis provides a low-profile add-on card
slot, a COM port, a VGA port, two USB 2.0 ports, one IPMI Ethernet port,
and two gigabit Ethernet ports per node.
Cooling system The chassis has four system fans powered from either the backplane or the
serverboards. If not powered from the backplane, the chassis powers the four
fans from the four motherboards so that when one of the motherboard
drawers is removed, the other motherboards will continue running all fans.
Air shrouds The chassis includes four plastic air shrouds that direct the airflow where
cooling is needed on each serverboard. Always use the air shrouds included
with your chassis on each serverboard.
Mounting rails The chassis includes a set of quick-release rails and can be placed in a rack
for secure storage and use. To set up your rack, follow the step-by-step
instructions included in this manual.

1: Introduction
Serverboard Features
At the heart of the SGI Rackable C2112-4GP3 server are dual-processor serverboards based on
the Intel®C612 chipset and designed to provide maximum performance. Four of these
serverboards can be mounted in the server chassis. Table 1-2 describes the major features of the
serverboards.
Table 1-2 Serverboard Features
Feature Description
Processors Each serverboard supports single or dual Intel Xeon®E5-2600 v3 Series
processors.
Memory Each serverboard has 16 DIMM slots supporting up to 1024 GB of
LRDIMM or 512 of RDIMM DDR4-2133/1866/1600 MHz registered ECC
memory.
SATA subsystem A SATA controller is integrated into the C612 chipset to provide up to a
10-port 6 Gb/s SATA3 subsystem. The SATA3 subsystem supports RAID 0,
1, 5, and 10. The SATA drives are hot-swappable units.
Note: The operating system you use must have RAID support to enable the
hot-swap capability and RAID function of the SATA drives.
PCI expansion
slots For each node, the server has one PCIe®3.0 x16 slot (Slot 1) available for
use with a riser card.
Onboard
controllers/ports A serverboard can include the following: – An Intel i350 gigabit (10/100/1000 Mb/s) Ethernet dual-channel controller
or an Intel X540 10 gigabit Ethernet dual-channel controller
– One 9-pin RS-232 port
– One Mellonox®Connect-X3 InfiniBand®supporting a single QSFP
connector One COM port
– One VGA (monitor) port
– Two USB 2.0 ports (Additional internal USB headers are included on the
serverboard.)
– One IPMI-dedicated LAN port
– Two Ethernet ports
Graphics
controller Each serverboard features an integrated ASPEED®2400 BMC with an
integrated VGA/2D graphics controller.
