Site planning timetable

The following guidelines can be used to monitor the progress of your pre-installation preparation. The time between placing an order and actual arrival can vary, and we recommend conferring with your HP representative to determine the best estimated delivery dates for preparation of your site.

The following are items that may require several weeks of lead time to complete:

• Acquiring required power connectors

• Arranging for an electrician

• Adding or modifying air conditioning

• Building alterations

• Placing an order for data comm equipment

Due to potential delays, we recommend that the suppliers of the listed services be contacted as soon as you have placed your order:

• Schedule the site planning visit with your HP CE to discuss questions concerning site planning.

• Select an appropriate location for the disk array and create a plan outlining the physical arrangement of the equipment, including related furniture.

16 HP StorageWorks Disk Array XP128: Site Preparation Guide

Preparing for installation

This chapter provides information for planning and preparing your site before and during installation of your HP Disk Array XP128.

Before installing your HP Disk Array XP128, your site data center computer room must meet the requirements described in this chapter.

Preparing for installation 17

Safety requirements

The following sections contain information to help you properly prepare your facility for the arrival of your disk array.

Site safety consideration

When making decisions concerning site safety, your first concern should be the safety of your personnel and then the safety of your equipment. Two major safety considerations for any computer site are fire safety and emergency power-off. If you have any questions about site safety, consult your HP CE, your insurance carrier, and local building inspectors for safety recommendations.

Fire safety

When considering fire safety, consult your insurance carrier and fire department for suggestions and recommendations. They can analyze your existing fire control systems, and advise you of any changes that may be needed. If you are building a new site, or modifying an old site, co nsult your local building codes for fire prevention and protection guidelines. You can also consult with your local HP CE and local fire inspectors for additional information.

Equipment servicing hazards

You, your HP CEs, and HP ASEs require safe access to the disk array. Along with the specifications listed in “General computer room requirements” (page 19), ensure that electrical or data communication cables do not create a safety hazard.

Electrical hazards

The disk array cabinet contains dangerous voltages. To prevent injury or death from electric shock, refer all electrical installation and service to qualified personnel.

18 HP StorageWorks Disk Array XP128: Site Preparation Guide

General computer room requirements

The purpose of a computer room is to maintain an ideal environment for your computer equipment, including your HP Disk Array XP128. The

following guidelines are recommended:

• Locate the computer room away from exterior walls of the building to avoid the heat gain from windows and exterior wall surfaces.

• When locating near exterior windows is unavoidable, use windows that are double or triple glazed and shaded to prevent direct sunlight from entering the computer room.

• Maintain the computer room at a positive pressure relative to the surrounding spaces to reduce the introduction of contaminants.

• Use a vapor barrier installed around the entire computer room envelope to restrain moisture migration.

• Caulk and vapor-seal all pipes and cables that penetrate the envelope.

• Use a 10-inch to 12-inch (25 to 31 mm) raised floor system for the most favorable room air distribution system if the under floor area is being used as part of the air circulation system.

Space planning

A site prep begins with your existing floor plan. The location of the new equipment should be selected and a new floor plan should be developed. You can use this section to satisfy the disk array physical requirements,

Preparing for installation 19

ensuring that your site is ready when the disk array arrives. Your floor plan should include the location of:

• Walls

• Cable paths, including lengths

• All equipment in your computer room, including furniture, cabinets, racks, data comm equipment, and systems

• Electrical outlets

• Immovable objects

• Floor vents

The HP Disk Array XP128

Your HP Disk Array XP128 is a high-performance disk array system. It is used to store large quantities of data in an efficient and secure manner. All components of the HP Disk Array XP128 are contained in a single cabinet, providing a complete storage system with a small equipment footprint.
