Consult your insurance carrier and local fire department for fire safety suggestions. They can analyze
your existing fire control systems and advise you about any required changes. If you are building a
new site or making structural changes to an existing site, consult your local building codes for fire
prevention and protection guidelines.
Avoiding equipment servicing hazards
Your staff and HP service personnel require safe access to the system. Running electrical and data
communication cables under a computer room's raised floor is the best way to ensure that they do
not create a safety hazard.
Preventing electrical hazards
The system racks contain dangerous voltages. To prevent injury or death from electric shock, refer all
electrical installation and service to qualified personnel.
Space planning
Space planning involves making sure that your computer room:
•
Is large enough to hold the new array and other equipment and furniture
•
Provides clearance around the array for service access and to ensure proper weight distribution
on the computer room floor
•
For raised floors, 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 communication equipment, and systems
d.
Floor cutouts
e.
Electrical outlets
f.
Connecting cables and power cords, including lengths
g.

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 with local contractors and your HP representatives.
