1: Overview
Features
The SGI Rackable C2005 are half-depth, rackmount servers that leverage a unique,
industry-leading approach to thermal management and power efficiency. They provide power
savings and higher levels of reliability in any data center environment. Mounted back-to-back,
C2005s can achieve typically twice the density over competing solutions. The C2005 offers
industry-leading direct-attached storage and expansion capabilities unheard of at a 1U-effective
rack density.
With the processing power of up to 672 cores and local storage capacity of up to 420 TB per
cabinet, the C2005 server is ideal for IT environments where space and power are constrained. Its
high-efficiency AC and DC power technologies reduce overall power consumption and heat
output in any legacy data center while increasing uptime and reliability.
Flexible Configurations
The highly modular C2005 server is built to order to address specific data center needs while
eliminating unnecessary costs. Based on an open architecture approach using AMD Opteron™ or
Intel® Xeon® processors, the C2005 server takes configuration flexibility to the next level with
two modular zones determining the balance between multiple 2.5” and 3.5” hard drive
configurations and expansion slot capabilities.
Leading Efficiency
The unique SGI approach to thermal management begins with each component inside our servers.
Leveraging high-efficiency power supplies, memory and processors, the patented SGI solutions
strive to draw the lowest possible wattage and reduce heat output. Innovative, award-winning AC
and DC power solutions at the system, cabinet and data center level enable any legacy data center
to immediately achieve reduced power costs.
High Density
Our unique half-depth form factor enables back-to-back mounting to achieve high density levels
of up to 44 dual-processor servers or networking gear per cabinet. Supporting today’s fastest
AMD and Intel dual- and quad-core processors, one cabinet can deliver—and effectively cool—
the compute power of 352 processing cores and 220TB of local storage.

System Configuration Options
007-5717-001 3
Simplified Serviceability
Time-saving Roamer™ remote management technology helps reduce
administrative resources and overhead. This single, highly intuitive interface
provides effortless local or remote control with total lights-out management.
Front-facing IO means RJ-45 ports, connectors and cables are located in front for
rapid service and maintenance.
Versatile 2.5” and 3.5” Local Storage Support
The C2005 server is an ideal match for many different applications. With up to ten
2.5” high-performance SAS or SSD drives, the C2005 is well-suited for
applications such as scale-out database servers. With up to five 3.5” SATA drives,
italso meetsthe need for configurationsrequiring high-capacity local storage. The
C2005 can even support a mixture of drive technologies and sizes.
System Configuration Options
This versatile system allows for many different types of build-to-order options.
There are a few limitations:
• Maximum of 2 sockets
• Maximum 288 GB of memory (18 x 16GB DIMMs)
• Maximum storage capacity of 15TB (SAS/SATA 3.5” HDDs)
• Onboard Networking: Dual GigE native + PCIe®-based cards
• IPMI 2.0 support
The compute configurations for the C2005 support both Intel and AMD
processors. Limitations are based on what options are available on current
motherboards in the E-ATX form factor. Table 1-1 charts the configuration
options.

Table 1-3 Front Panel Components
Component Description
Disk drives These removable hard drives can be placed in drive
carriers and can be hot-swappable. The drive carriers are
connected to the system internally via a custom backplane
that interfaces with a RAID storage card. Specifics of the
RAID card used depend on the system specifications of
your order.
DVD drive Depending on the configuration of your server, a
DVD/DVD-RW or CD/CD-RW drive may be present.
Also, in this area is space for an LCD display that is used
with a Roamer remote management module if one was
purchased with the server.
Front panel I/O The I/O interface to the motherboard. The configuration
of the various I/O ports is dependent on the motherboard
used in your configuration. For detailed I/O
specifications, refer to the motherboard manual included
with the documentation and accessory kit. Typical I/O
includes the following:
– serial port (RS-232, 9600 baud)
– USB ports
– PS-2 connector for mouse and keyboard
– VGA port
– Ethernet ports (RJ-45, eth0/eth1, 10/100/1000Mb)
LCD (Optional)
The LCD screen is used to display messages from the
Roamer remote management solution. The Roamer
module has the ability to display information relating to
the system that can be customized according to your need.

1: Overview
LED indicator lights These LEDs provide you with critical information related
to different parts of the system.
Green (PWR): The LED farthest to the left indicates that
power is applied to the server and the system is on. When
the LED is off, the system is off, even if the AC power
cord is plugged into the server.
Blue (HDD): The LED in the middle indicates that the
hard drive(s) are currently being accessed and activity is
occurring.
Red/Tri-color (ID2): The LED to the far right may have
several functions depending on the configuration of your
server. If your server was purchased with the Roamer
remote management module, then this LED can be turned
on or set to blink via Roamer so that a technician can
easily identify a unit that may need service.
Power button This single-push, push button is a power on/off button.
Whenthesystemisinanoff state,pushingthebutton once
powers the system on. When the system is in an on state,
pushing and releasing the button power the system off.
This button does not have a reset function.
Power supply
connector AC: Connect only 100-240 Volt AC, 3A or 5A maximum, 50-60 Hz. Use a standard AC connector to connect power
to the server. An AC power cord is included in your
documentation and accessory kit.
DC: Connect only.
Power switch This power switch turns the server on and off. It controls
the power supply that is inside the chassis.
