Rack planning resources

The rack resource kit ships with all HP branded or Compaq branded 9000, 10000, and H9 series racks. A summary of the content of each resource follows:

• Custom Builder is a web-based service for configuring one or many racks.

Rack configurations can be created using:

– A simple, guided interface – Build-it-yourself mode

For more information, refer to the HP website (http://www.hp.com/products/configurator

• The Installing Rack Products video provides a visual overview of operations

required for configuring a rack with rack-mountable components. It also provides the following important configuration steps:

– Planning the site – Installing rack servers and rack options – Cabling servers in a rack

16 HP StorageWorks Modular Smart Array 50 Storage Enclosure User Guide

– Coupling multiple racks

• The Rack Products Documentation CD enables you to view, search, and print

documentation for HP and Compaq branded racks and rack options. It also helps you set up and optimize a rack in a manner that best fits your environment.

If you intend to deploy and configure multiple servers in a single rack, refer to the white paper on high-density deployment on the HP website (http://www.hp.com/products/servers/platforms

Optimum environment

When installing the storage enclosure in a rack, select a location that meets the environmental standards described in this section.

Space and airflow requirements

To allow for servicing and adequate airflow, observe the following space and airflow requirements when deciding where to install a rack:

• Leave a minimum clearance of 63.5 cm (25 in) in front of the rack.

• Leave a minimum clearance of 76.2 cm (30 in) behind the rack.

• Leave a minimum clearance of 121.9 cm (48 in) from the back of the rack to

the back of another rack or row of racks.

HP storage enclosures draw in cool air through the front door and expel warm air through the rear door. Therefore, the front and rear rack doors must be adequately ventilated to allow ambient room air to enter the cabinet, and the rear door must be adequately ventilated to allow the warm air to escape from the cabinet.

CAUTION: To prevent improper cooling and damage to the

equipment, do not block the ventilation openings.

When a vertical space in the rack is not filled by a server or rack component, the gaps between the components cause changes in airflow through the rack and across the servers. Cover all gaps with blanking panels to maintain proper airflow.

Setup 17

CAUTION: Always use blanking panels to fill empty vertical

spaces in the rack. This arrangement ensures proper airflow. Using a rack without blanking panels results in improper cooling that can lead to thermal damage.

The 9000 and 10000 Series racks provide proper server cooling from flowthrough perforations in the front and rear doors that provide 64 percent open area for ventilation.

CAUTION: When using a Compaq branded 7000 Series rack, you

must install the high airflow rack door insert [P/N 327281-B21 (42U) or P/N 157847-B21 (22U)] to provide proper front-to-back airflow and cooling.

CAUTION: If a third-party rack is used, observe the following

additional requirements to ensure adequate airflow and to prevent damage to the equipment:

• Front and rear doors—If the 42U rack includes closing front and rear

doors, you must allow 5,350 sq cm (830 sq in) of holes evenly distributed from top to bottom to permit adequate airflow (equivalent to the required 64 percent open area for ventilation).

• Side—The clearance between the installed rack component and the

side panels of the rack must be a minimum of 7 cm (2.75 in).

Temperature requirements

To ensure continued safe and reliable equipment operation, install or position the storage enclosure in a well-ventilated, climate-controlled environment.

The maximum TMRA for most storage enclosure products is 35°C (95°F). The temperature in the room where the rack is located must not exceed 35°C (95°F).

CAUTION: To reduce the risk of damage to the equipment when

installing third-party options:

• Do not permit optional equipment to impede airflow around the

storage enclosure or to increase the internal rack temperature beyond the maximum allowable limits.

• Do not exceed the manufacturer’s TMRA.

Power requirements

Installation of this equipment must comply with local and regional electrical regulations governing the installation of IT equipment by licensed electricians. This equipment is designed to operate in installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75, 1992 (code for Protection of Electronic Computer/Data Processing Equipment). For electrical power ratings on options, refer to the product rating label or the user documentation supplied with that option.

WARNING: To reduce the risk of personal injury, fire, or damage to the equipment, do not overload the AC supply branch circuit that provides power to the rack. Consult the electrical authority having jurisdiction over wiring and installation requirements of your facility.

CAUTION: Protect the storage enclosure from power fluctuations and temporary interruptions with a regulating UPS. This device protects the hardware from damage caused by power surges and voltage spikes and keeps the storage enclosure in operation during a power failure.

When installing more than one storage enclosure, you may need to use additional power distribution devices to safely provide power to all devices. Observe the following guidelines:

• Balance the storage enclosure power load between available AC supply

branch circuits.

• Do not allow the overall system AC current load to exceed 80 percent of the

branch circuit AC current rating.

• Do not use common power outlet strips for this equipment.

• Provide a separate electrical circuit for each power supply in the storage

enclosure.

Setup 19

Electrical grounding requirements

The storage enclosure must be grounded properly for proper operation and safety. In the United States, you must install the equipment in accordance with NFPA 70, 1999 Edition (National Electric Code), Article 250, as well as any local and regional building codes. In Canada, you must install the equipment in accordance with Canadian Standards Association, CSA C22.1, Canadian Electrical Code. In all other countries, you must install the equipment in accordance with any regional or national electrical wiring codes, such as the International Electrotechnical Commission (IEC) Code 364, parts 1 through 7. Furthermore, you must be sure that all power distribution devices used in the installation, such as branch wiring and receptacles, are listed or certified grounding-type devices.

Because of the high ground-leakage currents associated with multiple storage enclosure connected to the same power source, HP recommends the use of a power distribution unit (PDU) that is either permanently wired to the building’s branch circuit or includes a nondetachable cord that is wired to an industrial-style plug. NEMA locking-style plugs or those complying with IEC 60309 are considered suitable for this purpose. Using common power outlet strips for the storage enclosure is not recommended.

Rack warnings

the equipment, be sure that:

• The leveling jacks are extended to the floor.

• The full weight of the rack rests on the leveling jacks.

• The stabilizing feet are attached to the rack if it is a single-rack

• The racks are coupled together in multiple-rack installations.

• Only one component is extended at a time. A rack may become
