Chapter 1
1. Introduction
Important: SGI Rackable server systems may sometimes require driver versions that are not
included in the original operating system release. When required, SGI provides these drivers on
an SGI Driver CD, which may ship with the system, or on the system disk (pre-installed in the
factory). For more information on this topic check with your sales or service representative.
The Rackable C1104G-RP5 server is a 1U rackmount system (see Figure 1-1 on page 2).
In addition to the serverboard and chassis, various hardware components may be included with
the system, as listed:
• Ten 4-cm chassis fans
• One internal air shroud
• Two passive 1U CPU heatsinks
• Riser cards as follows:
– One riser for a single PCIe x16 card, (left-front side internal GPU card)
– One riser for a single PCIe x16 card, (left-back side internal GPU card)
– One riser for a single PCIe x16 card, (right-front side internal GPU card)
– One riser for one low-profile PCIe 3.0 x8 card (external-facing rear card)
• Three power cables for GPU cards
• SATA accessories:
– One SAS/SATA backplane
– Four hot-swap disk drive carriers (RAID must be enabled for hot swap)
• Two power supplies
• One rackmount kit

Server Board Features
007-5839-001 3
Server Board Features
At the heart of the system is a dual-processor serverboard based on the Intel C602 chipset and
designed to provide maximum performance. The main features of the serverboard are described
in the following subsections.
Processors
The serverboard supports two four, six or eight-core, Intel Xeon E5-2600 series processors. Each
processorsits in anLGA 2011socket and is interconnected viaIntelQuickPathInterconnect(QPI)
link support; see the next subsection for more information on the QPI interconnects.
QPI Interconnect
Separate QPI link pairs connect the two processors and the I/O hub in a network on the
motherboard, allowing all of the components to access other components via the network.
Each QPI comprises two 20-lane point-to-point datalinks,onein each direction (full duplex), with
a separate clock pair in each direction, for a total of 42 signals. Each signal is a differential pair,
so the total number of pins is 84. The 20 data lanes are divided onto four “quadrants” of 5 lanes
each. The basic unit of transfer is the 80-bit “flit”, which is transferred in two clock cycles (four
20 bit transfers, two per clock.) The 80-bit “flit” has 8 bits for error detection, 8 bits for “link-layer
header” and 64 bits for “data”. QPI bandwidths are advertised by computing the transfer of 64 bits
(8 bytes) of data every two clock cycles in each direction
Memory
The serverboard has eight DIMM slots (four per processor) that support DDR3
1600/1333/1066/800 MHz RDIMMs. Note that memory speed support is dependent on the type
of CPU used on the mother board. Up to 256 GBs of total memory is supported.
Serial ATA and Optional SAS
A Serial ATA controller ASIC is integrated into the system serverboard to provide a standard
four-port SATA disk subsystem. Drive ports 0 and 1 are SATA 3.0 ports and the remaining drive
slots are SATA 2.0 ports. The hot-swappable SATA drives are connected to a backplane that
provides power, bus termination and configuration settings. Optional RAID 0, 1, 5, 6 and 10 are
supported. Note that your operating system must have RAID support enabled to accommodate hot

4007-5839-001
1: Introduction
swapping of disk drives. Certain RAID configurations require use of optional hardware. Check
with your sales or service representative to obtain information on set-up procedures if your system
did not come pre-configured with SATA or SAS RAID.
PCI Express Expansion Slots
The dual processor serverboard has three PCIe 3.0 x16 slots to support internal double-width GPU
cards. An additional slot at the rear of the server supports one PCIe 3.0 x8 low-profile card.
See the section “PCIe Expansion Cards” in Chapter 5 for more information on these topics.
Onboard Controllers/Ports
The color-coded I/O ports include (an internal COM header located on the serverboard), VGA
(monitor) port, two external USB 2.0 ports and two gigabit LAN Ethernet ports. A dedicated
external IPMI LAN port is also included.
Onboard Graphics Controller
The dual-processor serverboard features an integrated Matrox G200 video controller providing a
16MB DDR2 graphics interface through the system VGA connector. The Matrox video controller
in the 1U server features low power consumption, high reliability and superior longevity.
IPMI
IPMI (Intelligent Platform Management Interface) is a hardware-level interface specification that
provides remote access, monitoring and administration for your SGI Rackable C1104G-RP5
server platforms. IPMI allows server administrators to view a server’s hardware status remotely,
receive an alarm automatically if a failure occurs, and power cycle a system that is non-responsive.
Other Features
Other onboard features that promote system health include onboard voltage monitors, a chassis
intrusion header, auto-switching voltage regulators, chassis and CPU overheat sensors, virus
protection and BIOS rescue.

Server Chassis Features
007-5839-001 5
Server Chassis Features
The following subsections provide a general outline of the main features of the SGI Rackable
C1104G-RP5 server chassis.
System Power
The Rackable C1104G-RP5 1U server chassis features a redundant power supply composed of
two separate power modules. This power redundancy feature allows you to replace a failed power
supply without shutting down the system. Note that each power supply provides up to 1800 Watts
of power to the system.
Serial ATA Subsystems
The server chassis supports up to four 2.5-in SATA drives. Drives 0 and 1 are SATA 3.0
6-Gb/second slots, drives 2 and 3 are 3-Gb/second (SATA 2.0) disk drives. RAID drives are
hot-swappable units and are connected to a backplane that provides power and control. Note that
the operating system you have installed must support RAID to enable the hot-swap capability of
RAID drives. Certain RAID levels require use of optional hardware to support RAIDed hard disk
drives in the server.
Front Control Panel
The control panel on the C1104G-RP5 server provides you with system monitoring and control.
LEDs that indicate system power, HDD activity, network activity, system overheat and a system
overheat/fan-fail/ UID LED. A main power button and a system reset button are also included.
Serverboard and GPU Subsystem
The C1104G-RP5 server chassis is an ATX form factor chassis designed to be used in a 1U
rackmount configuration. The serverboard’s I/O backplane supports up to three standard size
(double-width) GPUs to enable high-quality GPU computing solutions. A 15-pin VGA port, two
USB 2.0 ports, two Gigabit LAN ports and a dedicated RJ-45 IPMI LAN port are also supported.
The GPUs process complex image calculations and then route the data out through the VGA port
on the serverboard. The GPUs, which come with a passive heatsink attached, have been tested for
use with this system.

6007-5839-001
1: Introduction
Important: Check with your SGI sales or service representative prior to using any GPU not
sourced at the SGI factory.
Any combination of these cards (up to a total of three) may have come bundled with the system.
Power for the GPU cards is provided via a GPU power cable from each of the GPUs to JPW3, 4,
6 and 7 on the serverboard (one cable for each card). Figure 1-2 on page 7 shows a general block
diagram of the C1104G-RP5 server’s processor and I/O chipset.
GPU Features
Each of the GPUs will feature some or all of the following:
• Hundreds of GPU cores in each card that can deliver more than 660 Gigaflops of
double-precision and over one Teraflop of single-precision calculations.
• ECC protected internal register files, L1/L2 caches, shared memory, and external DRAM.
• Up to 6 GB of GDDR5 memory per GPU enhances performance and reduces data transfers
by keeping larger data sets in local memory attached directly to the GPU.
• Integrates the GPU subsystem with the C1104G-RP5 server’s monitoring and management
capabilities such as IPMI.
• Onboard L1 and L2 caches that accelerate algorithms and sparse-matrix multiplication.
• Provides faster context switching, concurrent kernel execution and improved thread block
scheduling.
• Enhances overall system performance by transferring data over the PCIe bus while the
computing cores are processing other data.
• Provides a flexible programming environment with broad support for various programming
languages and APIs.
Cooling System
The 1U server chassis has a cooling design that includes ten internal 4-cm counter-rotating Pulse
Width Modulated (PWM) system cooling fans located in the chassis. An air shroud channels the
airflow from the system fans to efficiently cool the processor and GPU areas of the system. Each
power supply module also includes an internal cooling fan. All chassis and power supply fans
operate continuously.
