Chapter 1 1. Overview This document provides information that helps management and site preparation personnel prepare for an SGI Origin 3900 server system installation. It includes general site planning concepts as well as specific site requirements that you may use as a guide during the site planning and preparation process.
Chapter 2 2. Site Preparation Concepts This chapter of the SGI Origin 3900 Server Site Planning Guide provides a general overview of the site planning process and information about the issues that are involved in any site preparation. For the system-specific site planning information, refer to the subsequent chapters of this document. Not all of the items listed here apply to every installation; however, it is a good idea to briefly consider each question for any system installation.
2: Site Preparation Concepts • Is the floor strong enough to support the weight of the system? The rack loaded with bricks can be very heavy. Determine the weight of each rack and verify that the floor along the delivery route can handle the weight. Refer to Table 5-1 for the maximum weight per system rack. • Is the elevator capable of lifting the system? If the intended delivery route includes an elevator, check its weight capacity and size against the system specifications listed in Table 5-1.
Electrical Requirements • Will the intended location enable you to conveniently perform routine operations, such as loading and unloading tapes or other media, attaching cables, and so on? • Is the floor of the intended final location strong enough to support the weight of the system and any future expansions? Large systems should be installed in computer rooms with raised floors. Pay particular attention to floor loading and weight distribution in this case.
2: Site Preparation Concepts Voltage Requirements SGI Origin 3900 servers ship with the option of either single-phase or three-phase input power. Refer to the section titled “System Power Requirements” in Chapter 6 for the voltage requirements of the chassis. You must ensure that your account manager knows of your needs before the system is ordered. Ensure that the required voltage is available and is within a reasonable distance of the intended location.
Electrical Requirements Grounding Requirements • Ensure that the ground has sufficiently low impedance in order to limit the voltage to ground and to facilitate the operation of protective devices in the electrical circuit. • Ensure that all grounds entering the room are interconnected somewhere within the building to provide a common ground potential. This includes any separate power sources, lighting, convenience outlets, and other grounded objects such as building steel, plumbing, and ductwork.
2: Site Preparation Concepts It is very important that you consider the inrush current of the system when you select a UPS or SPS. Unlike power-company lines, these power-conditioning devices may not be able to supply the current that is required during power-on, even if they are sized appropriately for nominal current loads. For more information, refer to the following “Power-line Treatment” section. It is possible for the inrush current drawn by a device to cause a slight drop in the line voltage.
Thermal Requirements Thermal Requirements It is important that the SGI Origin 3900 servers be maintained within their rated thermal range. Refer to the section titled “Environmental Requirements” in Chapter 6 for the temperature ranges for each rack, both operating and nonoperating as well as the recommended operating ambient temperature. Typically, the upper limit of the temperature range is more likely to become a problem than the lower limit.
2: Site Preparation Concepts Calculating Thermal Load You can calculate the thermal load as follows: 1. Add the wattages of all the items in the room. 2. Calculate Btu/hour by multiplying the total wattage by 3.41. 3. Calculate the kcal/hour by multiplying the total wattage by 3.23. 4. Calculate the tons of air-conditioning load by dividing Btu/hr by 12,000.
Environmental Requirements Cooling In Mission-critical Installations In mission-critical installations, it is important to consider what would happen if an air conditioner failed.
2: Site Preparation Concepts Electrostatic Discharge SGI designs and tests its products to ensure that they resist the effects of electrostatic discharge (ESD). However, it is still possible for ESD to cause problems that range from data errors and lockups to permanent component damage. To protect the systems from ESD, follow these precautions: • Minimize the use of carpeting at computer locations (or consider special static-reducing carpet). • Ensure that all electronic devices are properly grounded.
Ergonomic Requirements Ergonomic Requirements When you select a physical location, pay attention to ergonomic considerations. The location of a system often restricts the location of the devices that attach to it, such as monitors, keyboards, and so on. Decisions that are made during the installation process can affect workers much later.
Chapter 3 3. SGI Origin 3900 Server Features, Configurations, and Components The SGI Origin 3900 server is the latest model in the SGI Origin 3000 series. An Origin 3900 configuration has four times the computational density of the former Origin 3000 series configurations. The Origin 3900 server provides up to 128 processors and 256 GB of memory per compute rack and scales to 512 processors and 1 TB of memory in a shared-memory image.
3: SGI Origin 3900 Server Features, Configurations, and Components SGI Origin 3900 Server Configurations SGI configures the SGI Origin 3900 server to contain both standard and optional equipment. The configuration of each computer system depends on customer requirements. The Origin 3900 server configurations range from a 2-processor, single-rack system to a 512-processor, multiple-rack system. SGI Origin 3900 server configurations that include more than 512 processors are possible via clustering.
SGI Origin 3900 Server Bricks SGI Origin 3900 Server Bricks The SGI Origin 3900 servers are based on assemblages of CPU/memory, I/O, and peripheral enclosures referred to as bricks. These bricks may be mixed and matched within a standard 19-in. system rack to provide the desired system configuration. NUMAlink cables connect the bricks. Customers may install bricks in any existing standard 19-in.
