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:
• 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.

Preparing for installation
This chapter provides information for planning and preparing your site
before and during installation of your HP Disk Array XP1024.
Before installing your HP Disk Array XP1024, your site data center
computer room must meet the requirements described in this chapter.

18 HP StorageWorks Disk Array XP1024: Site Preparation Guide
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, 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 cabinets contain dangerous voltages. To prevent injury or
death from electric shock, refer all electrical installation and service to
qualified personnel.

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 Disk Array XP1024. 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 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 25 to 31 cm (10 to 12 inch) raised floor system for the most
favorable room air distribution system if the under floor area is being
used as an 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,
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 XP1024
Your HP Disk Array XP1024 is a high-performance disk array system. It is
used to store large quantities of data in an efficient and secure manner. The
components of the HP Disk Array XP1024 are contained in one of two
types of cabinets.
Each HP Disk Array XP1024 has one disk controller cabinet (DKC), which
contains the controller electronics for the disk array, and one to five
disk-cabinet units (DKUs), which contain the hard disk drives.
When only XP1024 DKUs are used, the disk array can have one to four
XP1024 DKUs. The figure below shows a Disk Array XP1024 with four
XP1024 DKUs.When both XP1024 and XP512 DKUs are used, the DKU
types cannot be mixed on the same side of the DKC.
