Cabinet and Rack Specifications
|
The Sun Storage 6180 Array can be installed in any NEBS-compliant, standard 19” 4-post cabinet with 24-26” spacing between posts. This includes all StorEdge Expansion, SunFire, Sun Rack II, and Sun Rack 900/1000 cabinets. This chapter describes the physical, environmental, and electrical requirements for these cabinets, as follows:
To ensure safe and proper operation of the system, and ease of maintenance, make sure that all of these requirements have been met before beginning the installation of the cabinet.
Sun StorEdge Expansion Cabinet
This section describes the physical, electrical, and environmental requirements for the Sun StorEdge Expansion cabinet.
The floor area at the installation site must provide enough stability to support the weight of the cabinet and installed trays, sufficient space for installation and servicing of the cabinet and components, and sufficient ventilation to provide a free flow of air to the cabinet.

Temperature, Humidity, and Altitude
TABLE 2-9 lists operating and nonoperating relative humidity, and altitude ranges for the Sun Fire cabinet. The table also provides the optimum operating condition in the recommended operating environment. Operating computer equipment for extended periods of time at or near the temperature or humidity extremes is known to significantly increase the failure rate of hardware components.

A table showing the operating and nonoperating temperature, relative humidity, and altitude ranges of the Sun Fire cabinet.
Note: If you plan to operate a storage array at an altitude between 1000 m to 3000 m (3280 ft to 9842 ft) above sea level, lower the environmental temperature 1.7˚C (3.3˚F) for every 1000 m (3280 ft) above sea level.
Airflow and Heat Dissipation
The air intake screens act as electro-magnetic interference (EMI) and radio frequency interference (RFI) filters, stopping both EMI and RFI emissions from the system. These screens are honeycomb screens, which also collect and trap dust and debris particles.
The Sun Fire cabinet’s air intake screens require periodic inspection and cleaning. To prevent restricted airflow and possible equipment failure, inspect the air intake screens for debris and trapped particles every three months of operation. Consider the level of debris on the screens and surrounding area in the decision as to when to remove and clean the air intake screens.
Power Requirements
The AC power sources must provide the correct voltage, current, and frequency specified on the module model and serial number label. The cabinet can run within the limits shown in TABLE 2-10.

Sun Rack II Cabinet
This section describes the physical, electrical, and environmental requirements for the Sun Fire II cabinet.
The floor area at the installation site must provide enough stability to support the weight of the cabinet and installed trays, sufficient space for installation and servicing of the cabinet and components, and sufficient ventilation to provide a free flow of air to the cabinet.
The Sun Rack II Cabinet is 120 cm (47 in.) deep, 60 cm (23.6 in.) wide, and provides 42U (186.7 cm--73.5 in.) of equipment space. It has a weight of 190 kg (420 lb) with a capacity for holding up to 907 kg (2000 lb) of equipment.
| Note - Both the Sun 6180 controller module and the disk array trays conform to the 48.3-cm (19-in.) rack standard. For more information see the Sun Rack II User’s Guide.

Access Route Guidelines
Moving the rack to the installation site:
- If the existing loading dock meets height and ramp requirements for a standard freight carrier truck, you can use a pallet jack to unload the rack.
- If not, you must provide a standard forklift or other means to unload the rack, or request the rack be shipped in a truck with a lift gate.
| Note - Leave the rack in its shipping packaging until it reaches its final destination. The entire access route to the installation site should be free of obstructions and raised patterns that can cause vibration.

Depending on the configuration, an additional rack can be placed next to the master rack to obtain a fully configured system. This configuration would consist of one rack with the controller tray and 12 drive trays, then 4 additional drive trays in the second or expansion rack.
| Note - Longer customer supplied Fibre Channel cables are needed with this configuration for connecting the expansion trays to the controller in the master rack.

Power Requirements
The AC power sources must provide the correct voltage, current, frequency, and connectors specified on the module type and serial number label.
The following guidelines are a best practice when determining power requirements:
- Use dedicated AC breaker panels for all power circuits that supply power to the PDU.
- Electrical work and installations must comply with applicable local, state, or national electrical codes.
- Contact your facilities manager or a qualified electrician to determine what type of power is supplied to your building.
DC Power
- An optional -48Vdc power is supplied by a centralized DC power plant.
- Site wiring must include a protective ground connection to the -48Vdc power source/plant.
- The nominal 6180 DC rating is -48 to -60Vdc with a tolerance of +20%, -15%.
Power Distribution
The design of this rack includes four Sun Storage, half-height, 5 kVA power distribution units (PDUs) that creates a dual grid power system. This power system consists of four power strips, using separate 30 Amp circuits. Each with 12 outlets, protected by two circuit breakers for a total of 48 outlets, or 24 outlets per grid.
Each circuit requires:

Circuit Breaker Capacity and Characteristics
Each Sun Rack II requires its own customer-supplied circuit breaker and AC receptacle for each power input cord. Provide a stable power source, such as an uninterruptible power system (UPS), to reduce the possibility of component failures.
If the computer equipment is subjected to repeated power interruptions and fluctuations, it is susceptible to a higher component failure rate than it would be with a stable power source.
Environmental Requirements
This section describes the environmental conditions for the Sun Rack II cabinet.
| Note - Typical Sun equipment environmental requirements that mount in a Sun Rack II. Although most computer equipment is designed to operate in environmental conditions of 20% to 80% humidity, industry best practices recommends computer rooms maintain a relative humidity of 40% to 50% for best performance.

Airflow and Heat Dissipation
Cabinet airflow is from the front to the back.
Allow at least 76 cm (30 in.) in front of the cabinet, and at least 61 cm (24 in.) behind the cabinet, for service clearance, proper ventilation, and heat dissipation.

Airflow and Heat Dissipation
Cabinet airflow is from front to back. Allow at least 30 inches in front of the cabinet, and at least 24 inches behind the cabinet, for service clearance, proper ventilation, and heat dissipation.
Power Requirements
The AC power sources must provide the correct voltage, current, and frequency specified on the module model and serial number label. The cabinet can run within the limits shown in TABLE 2-19.

DC Power
- An optional -48Vdc power is supplied by a centralized DC power plant.
- Site wiring must include a protective ground connection to the -48Vdc power source/plant.
- The nominal 6180 DC rating is -48 to -60Vdc with a tolerance of +20%, -15%.
