or making structural changes to an existing site, consult your local building codes for fire prevention and
protection guidelines.
Equipment serv
icing hazards
Your staff and H
P
service personnel require safe access to the disk array. Running electrical and data
communicatio
n
cables underneath your computer room’s raised floor is the best way to ensure that they
do notcreateasafety hazard.
Electrical hazards
The disk array equipment racks contain dangerous voltages. To prevent injury or death from electric
shock, refer all electrical installation and service to qualified personnel.
Space planni
ng
re quirements
Space planning involves making sure that your computer room:
• Is large enough to hold the new array and other equipment and furniture
• Provides cl
earance around the array for service access and to ensure proper weight distribution
on the comp u
ter
room’s floor
• Includes correctly positioned floor cutouts for the array’s power and data cables
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 comm e quipment, and systems
d. Floor cutouts
e. Electrical outlets
f. Interconnecting cables and power cords, including lengths
g. Floor vents
2. Developanew floor plan that includes the locations of all of the above items plus the disk array
and
any new items a dded to support it. Include flexibility to accommodate ad ditional e quipment as
your requirements increase.
3. Implement the new floor plan, leaving empty space where the array will be installed. If the n ew floor
plan
requires construction changes, consult with local contractors and your HP representatives.
Raise
d
floor requirements
The co
mputer room floor must be able to support the total weight of the equipment as well as localize d
weig
ht at
each caster or foot of the equipment cabinets. 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:
• Allows weight to be spread evenly across the floor
• Provides an under-floor area for running interconnecting cables conveniently and unobtrusively
• All
ows optimum distribution of conditioned air
