The space planning process

1. Document your computer room's existing floor plan, including locations of these items:
a.
Immovable objects, such as structural support columns
b. Walls
c.
All equipment, furniture, cabinets, racks, data communication equipment, and systems
d. Floor cutouts
e.
Electrical outlets
f. Connecting cables and power cords, including lengths
g.
Floor vents
2. Develop a new floor plan that includes the locations of all of the above items plus the disk array
and any new items added to support it. Include flexibility to accommodate additional equipment
as your requirements increase.
3. Implement the new floor plan, leaving empty space where the array will be installed. If the new
floor plan requires construction changes, consult local contractors and HP representatives.

Floor requirements

XP disk arrays can be installed on solid surface (concrete) or raised floors.
All computer room floors must meet the following requirements:
• The floor must be able to support the total weight of the equipment as well as localized weight at
each caster or foot of the equipment cabinets. For more information, see
"Estimating required floor load
• The surface of the floor must be covered or treated with conductive material. For more information
see "Floor covering
WARNING!
If metal is used in the construction of the computer room floor, ensure that there is a common ground
connection between it and the ground or floor that it is built on to avoid possible build up of different
voltage potentials. Noncompliance can result in serious injury to personnel and damage to equipment.

Raised floor requirements

A common method of preparing an adequate floor for a computer room is to construct a raised floor
over the building floor.
A raised floor has these advantages:
• Allows weight to be spread evenly across the floor
• Allows cables to be run conveniently and unobtrusively under the floor
• Allows optimum distribution of conditioned air
Raised floors have the following additional requirements:
• Raised floor access ramps must not exceed a 10 degree slope.
