The CloudRack C2 cluster server is comprised of a stand-alone 24U or 42U rack. The 24U rack holds up to 22 compute trays and the 42U rack holds up to 38 trays. The compute trays house serverboards, hard drives, and graphics or I/O options. Stand-alone enclosures are mounted on castors so they can be moved within the server room or compute lab environment. Check with your sales or service representative before loading any operating system on your server not provided by the SGI factory or service organization.
In addition to the compute trays and chassis, various hardware components may be included as part of your CloudRack C2 configuration as listed below:
• SATA Accessories: A minimum of one disk drive (per serverboard) is required for operation.
One (1) internal SATA backplane per compute node. One (1) SATA cable set per compute node. SAS hard drive options are also available.
• Two (2) optional PCI Express x16 riser cards (one per compute serverboard).
2 007-5681-001
Overview
• Rackmount hardware for mounting the enclosure in a half-height or full-height rack.
• One (1) CD containing drivers and utilities plus optional CDs depending on order configuration.
• One or two Gbit Ethernet or (optional) InfiniBand switches are used per enclosure.
Example Nodeboard Features
At the heart of each CloudRack C2 compute tray lies one or more multi-processor based node boards (serverboards). These serverboards may be based on Intel or AMD chipsets, depending on the configuration ordered.
Processors
The cluster server system can support the following minimum/maximum configuration of processor cores:
• 24U system: 8/1056 processor cores
• 42U system: 8/1824 processor cores
The exact type of processors provided with your system depends on the specific configuration you ordered. Check with your sales or service representative for information on processor availability, upgrades and compatibility. The following are examples of types available for the CloudRack C2:
• One or two dual-socket Intel® Xeon® 5600 processor series-based serverboards per tray
• Six single-socket Intel® Atom® processor series-based MicroSlice serverboards per tray
• One or two dual-socket, AMD Opteron™ 4100 or 6100 processor series-based serverboards per tray
Higher-performance compute (HPC) serverboards support two Intel® Xeon quad-core processors
(a total of 4 quad-core processors per compute tray).
DIMM Memory
Memory configuration varies depending on the processor board type ordered with your system tray(s). DIMM population requirements vary from one per serverboard up to 12 per serverboard, using DIMM speeds from 667 MHz to 1333 MHz.
007-5681-001 3

System Operation and Troubleshooting
The first half of this chapter describes the basic steps needed to get your SGI CloudRack C2 up and running. Following these steps in the order given should enable you to have the system operational within a minimum amount of time. The second half of this chapter provides you with some basic troubleshooting advice. Use these sections to eliminate simple problems or obtain information that may be needed by your service provider.
Unpacking the System and Choosing an Operating Location
You should inspect the box the system was shipped in and note if it was damaged in any way. If the server itself shows damage you should file a damage claim with the carrier who delivered it.
When you decide on a suitable location for the system, it should be situated in a clean, dust-free area that is well ventilated. Avoid areas where heat, electrical noise and electromagnetic fields are generated. You will also need it placed near a dedicated 200-240 Volt grounded single-phase
(L6-30) power outlet or 3-phase power outlet.
The CloudRack C2 is designed to fit into a computer lab or server room environment. Take care to maintain the following operating conditions:
• The system should have a six-inch (15 cm) minimum top air clearance.
• The system should be protected from harsh environments that produce excessive vibration and heat.
• The system should be kept in a clean, dust-free location to reduce maintenance problems.
• Available power must be rated for large computer operation (30 amps at 200-240 Volts).
007-5681-001 11
2: System Operation and Troubleshooting
Placing Rackmounted Systems
Be sure to read the “Rack Precautions” on page 12 if you are having the system installed on site.
Choosing a Setup Location
Leave enough clearance in front of the rack to enable opening the front door completely
~48 inches (1.2 meters).
Leave sufficient clearance in the back of the rack to allow for adequate airflow and ease in servicing.
Rack-mounted systems are generally placed in a Restricted Access Location (dedicated equipment rooms, service closets and the like).
Rack Precautions
• Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with the full weight of the rack resting on them.
• The enclosure should be installed in the lowest part of the rack possible.
• In a tall rack installation, stabilizers should be attached to the rack if available.
• Always make sure the rack is stable before connecting power to the rack and internal inclosure.
• Always keep the rack's front door and all panels and components on the servers closed when not servicing to maintain proper cooling.
• When moving a rack with pivoting casters, push the rack from front to back. Pushing from the side could destabilize the rack if a caster encounters a floor irregularity/dropoff.
Server Precautions
Review the electrical and general safety precautions in Chapter 1.
For extra protection, use a regulating uninterruptible power supply (UPS) to protect the cluster server’s power supplies from power surges, voltage spikes and to keep your system operating in case of a power failure. This is an optional device not provided by SGI with your system.
12 007-5681-001
Placing Rackmounted Systems
Service personnel should always allow the hot plug disk drives and power supply modules to cool before touching them. To maintain proper cooling, always keep the enclosure doors closed when it is not being serviced.
Make sure all power and data cables are properly connected and not blocking the enclosure airflow.
Rack Operating Considerations
Use the guidelines in the following subsections to properly use and maintain a server in a rack.
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack environment may be greater than the ambient temperature of the room. Therefore, consideration should be given to installing the equipment in an environment compatible with the manufacturer’s maximum rated ambient temperature.
Reduced Airflow
Equipment should be mounted into a rack so that the amount of airflow required for safe operation is not compromised.
Mechanical Loading
Equipment should be mounted into a rack so that a hazardous condition does not arise due to uneven mechanical loading.
Circuit Overloading
Consideration should be given to the connection of the equipment to the power supply circuitry and the effect that any possible overloading of circuits might have on over-current protection and power supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
007-5681-001 13
2: System Operation and Troubleshooting
Reliable Ground
A reliable ground for the system must be maintained at all times. To ensure this, the rack itself should be grounded. Particular attention should be given to power supply connections other than the direct connections to the branch circuit (i.e. the use of power strips, etc.). Note that all power and data cables should be routed in such a way that they do not block the airflow generated by the enclosure fans.

CPU Temperature/System Temperature
This feature displays current temperature readings for the CPU and the System.
The following items will be displayed for your reference only:
CPU Temperature
The CPU thermal technology that reports absolute temperatures (Celsius/Fahrenheit) has been upgraded to a more advanced feature by Intel in its newer processors. The basic concept is each
CPU is embedded by unique temperature information that the motherboard can read. This
‘Temperature Threshold’ or ‘Temperature Tolerance’ has been assigned at the factory and is the baseline on which the motherboard takes action during different CPU temperature conditions (i.e., by increasing CPU Fan speed, triggering the Overheat Alarm, etc.) Since CPUs can have different
‘Temperature Tolerances’, the installed CPU can now send information to the motherboard regarding what its ‘Temperature Tolerance’ is, and not the other way around. This results in better
CPU thermal management.
The manufacturer has leveraged this feature by assigning a temperature status to certain thermal conditions in the processor (Low, Medium and High). This makes it easier for the user to understand the CPU’s temperature status, rather than by just simply seeing a temperature reading
(i.e., 25 o C). The CPU Temperature feature will display the CPU temperature status as detected by the BIOS:
Low – This level is considered as the ‘normal’ operating state. The CPU temperature is well below the CPU ‘Temperature Tolerance’. The motherboard fans and CPU will run normally as configured in the BIOS (Fan Speed Control).
User intervention: No action required.
39
4: HPC Server BIOS Information
Medium – The processor is running warmer. This is a ‘precautionary’ level and generally means that there may be factors contributing to this condition, but the CPU is still within its normal operating state and below the CPU ‘Temperature Tolerance’. The motherboard fans and CPU will run normally as configured in the BIOS. The fans may adjust to a faster speed depending on the
Fan Speed Control settings.
User intervention: No action is required. However, consider checking the CPU fans and the chassis ventilation for blockage.
High – The processor is running hot. This is a ‘caution’ level since the CPU’s ‘Temperature
Tolerance’ has been reached (or has been exceeded) and may activate an overheat alarm.
User intervention: If the system buzzer and Overheat LED has activated, take action immediately by checking the system fans, chassis ventilation and room temperature to correct any problems.
Note: The system may shut down if it continues for a long period to prevent damage to the CPU.
The information provided above is for your reference only. For more information on processor thermal management, reference Intel’s Web site at www.Intel.com or contact your support representative.
System Temperature: The system temperature will be displayed (in degrees in Celsius and
Fahrenheit) as it is detected by the BIOS.
Fan Speed Control Monitor
This feature allows the user to decide how the system controls the speeds of the on-board fans. The
CPU temperature and the fan speed are correlative. When the CPU on-die temperature increases, the fan speed will also increase, and vice versa. Select Workstation if your system is used as a
Workstation. Select Server if your system is used as a Server. Select “Disabled, (Full Speed
@12V)” to disable the fan speed control function and allow the on-board fans to constantly run at the full speed (12V). The Options are: 1. Disabled (Full Speed), 2. Server Mode, 3. Workstation
Mode.
Fan1 ~ Fan 4 Reading
This feature displays the fan speed readings from fan interfaces Fan1 through Fan5.
