Preparing the Site Before the System Arrives

Install the Sun Blade 6048 modular system in accordance with the local safety codes and regulations at the facility site. You must be familiar with and adhere to the safety precautions in the Sun Blade 6000 and Sun Blade 6048 Modular System Safety and Compliance Guide (E26034).

Do not make mechanical or electrical modifications to the equipment. Oracle, Inc. is not responsible for regulatory compliance of a modified Oracle product.

Load-Bearing and Handling Precautions

A fully configured Sun Blade 6048 modular system can weigh in excess of 2500 pounds (1134 kg) while in its shipping container, and 2300 pounds (1044 kg) when unpacked. Any floor that this system will cross, or surface on which the system is placed, must be able to support these loads.

The system is shipped on a pallet. You must maintain the system in a vertical, upright position while it is in its shipping container. Be sure you use enough personnel when moving the system, especially on sloping loading docks and ramps, to gain access to a raised computer room floor. Move the system slowly and deliberately, and ensure that the floor is free of foreign objects, cables, or other obstructions.

Power and Electrical Requirements

The Sun Blade 6048 modular system uses two 200-240V, 8400W power supply modules per shelf. The amount of power that the system consumes is dependent on its configuration, that is, the number of active modular components installed. To determine the power redundancy requirements, you need to know:

The system requires a minimum of two AC inputs per shelf. To provide 2N power redundancy at a 8400 W consumption level, and to ensure that the system can tolerate a loss of one power supply, the system should never exceed 9375 W per shelf of power consumption at any given time.

The power requirements for different components in the Sun Blade 6048 System are provided via the power calculator:

The AC power requirements for the Sun Blade 6048 modular system are summarized in AC Power Requirements .

The data center must meet the following electrical requirements for installation of a Sun Blade 6048 System:

You can configure the Sun Blade 6048 modular system for grid redundancy by using two AC line feeds and the appropriate modular power system. Grid redundancy refers to the performance of the chassis power subsystem in the intended AC configuration. For grid redundancy, the AC configuration is supplied AC power from two independent feeds, which can be called Line A and Line B. By connecting one power supply to the Line A feed and one power supply to the Line B feed, the system can tolerate the failure of one power supply or the complete loss of either AC feed.

Power Budgeting

Use the power calculator for estimating the power consumption of your system:

The intent of the power calculator is to provide guidance for estimating the electrical and heat loads for typical operating conditions. The "Max power" results shown in the calculator (at 100% workload) represent server module power consumption measurements with CPUs at 100% utilization running SPECjbb2005. The "Idle power" results shown in the calculator represent power consumption measurements taken from server modules with operating systems booted and stabilized, yet running at minimal utilization.

Results shown are representative of measurements taken with room temperatures below 25 o C. Actual power consumption will vary with application type, application utilization and ambient temperature. Whenever possible, actual measurements are recommended.

Use these specifications for planning purposes only. The system’s actual power requirements are dependent on which components are included in your configuration.

Cooling Requirements

Every watt of power used by the system is dissipated into the air as heat. The thermal power dissipation of the shelf in a 9375W 2N configuration is 32,000 BTU/h. This requires that the data center heating, ventilation, and air conditioning (HVAC) system must accommodate the maximum heat release of a fully configured system, as well as any other systems in the data center.

The amount of heat output per Sun Blade 6048 System varies, depending on the system configuration. The systems are equipped with fans that route cool air throughout the chassis from front to rear. The fans are speed-controlled based on system temperature sensors. Typical airflow (for room temperatures below 23 oC) is about 844 CFM per shelf. Maximum possible airflow is about 1460 CFM per shelf.

As long as the necessary air conditioning is provided in the data center to dissipate the heat load, and sufficient space and properly vented door openings are provided at the front and back of rackmounted systems (see Service and Aisle Clearance Requirements), the system fans will enable the system to work within the temperature specifications for systems in operation (see Environmental Specifications ). Thermal characteristics of the Sun Blade 6048 Chassis system are provided in  Thermal Design Specifications.

Temperature and Humidity Requirements

Avoid temperature and humidity extremes. The operating and nonoperating temperature specifications listed in Environmental Specifications  reflect the system’s hardware limits, in order to meet all functional requirements. Note that the operating temperatures apply to the air entering the system and not necessarily the temperature of the air in the aisles.

The optimum operating ambient temperature and humidity ranges are the recommended operating environment. Operating the system within the ambient temperature range is optimal for system reliability. At 23 oC (73.4 oF) it is easy to maintain safe relative humidity ranges and to provide a buffer if the environmental support system fails.

Ambient relative humidity levels between 45% and 50% are the most suitable for system operations to:

Conditions should not be allowed to fluctuate by more than 5.5 oC (10 oF) or 10% relative humidity during a 60-minute period.

Airflow Requirements

The system uses forced air to draw in ambient air for cooling from the front of the chassis, while heated air exits the rear of the chassis. The design of the system provides two primary regions of airflow: The lower airstream cools the Server Modules, and the upper airstream cools the power supplies, Chassis Monitoring Modules, Sun Blade 6048 Network Express Modules, and PCI Express Modules.

The rear fan cage includes eight rear fan modules, each module having two fans, for a total of 16 fans. The fans draw cool air through the front of the Server Modules and exhaust heated air through the back of the chassis. This results in typical measurements of approximately 844 CFM (cubic feet per minute) of total airflow through a shelf.

The upper airstream provides forced air by using a combination of internal fans within each power supply.

Follow these airflow guidelines:

Clearance for Service and Aisle Requirements

To enable installation and servicing of the system, including access to system cables, follow these space restrictions.

Table 1-1 Service and Aisle Clearance Requirements

Service Access Requirement
Front cold aisle
4 feet (1.22 m); required for inserting server modules
Back hot aisle
3 feet (0.9 m); required for cable access

Arrange cabinets in a hot aisle/cold aisle layout. This layout enables cool air to flow through the aisles to the system’s front air intake and enables heated air to flow from the system’s back exhaust. A hot aisle/cold aisle layout eliminates the direct transfer of hot exhaust air from one system into the intake air of another system.
