Site Planning Timetable
The following guidelines can be used to monitor the progress of your
preinstallation preparation. The time between placing an order to 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:
•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.

PREPARING FOR INSTALLATION
This chapter provides information for planning and preparing your site
before and during installation of your HP SureStore E Disk Array XP48.
Before installing your HP SureStore E Disk Array XP48, your site data
center computer room must meet the requirements described in these
sections:
•“Safety Requirements”(page 18)
•“General Computer Room Requirements”(page 19)
•“Physical Requirements”(page 23)
•“Service and Cable Routing Space Requirements”(page 27)
•“Data Comm Requirements”(page 31)
•“Electrical Requirements”(page 34)

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 on 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, consult
your local building codes for fire prevention and protection guidelines. You
can also consult your local HP CE and local fire inspectors for additional
information.
Equipment Servicing Hazards
You and 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.

Preparing for Installation 19
General Computer Room Requirements
The goal of a computer room is to maintain an ideal environment for your
computer equipment, including your HP SureStore E Disk Array XP48.
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 exterior windows are unavoidable, use windows that are double
or tripled 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 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 raised floor system for the most favorable
room air distribution 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,
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
