HP StorageWorks XP12000 Disk Array Site Preparation Guide (AE002-96040, March 2008)

• The disk array (see “Weights” on page 20)
• Other equipment
• Furniture such as desks, chairs, and storage cabinets
• Computer room personnel
• Moving equipment, such as forklifts, dollies, and similar items
The lower the floor load rating, the more clearance is required around the array to distribute the
equipment weight correctly. If your computer room is too small to allow for minimum required clearance
around the array, you may need to increase the floor load rating. For more on required clearance,
see “Floor clearance requirements” on page 30.
Floor covering requirements
HP recommends a tiled floor.
CAUTION:
HP strongly discourages the use of carpeting, including antistatic varieties, within 6.0 m (20 ft.) of the disk
array. Over time, carpeting may shed dust that can cause problems with the disk array.
CAUTION:
If your computer room has carpeting, place static discharge mats so that personnel must walk across them
before touching any part of the array. Failure to comply with this precaution can result in equipment
damage through static discharge.
Space planning requirements
Space planning involves making sure that your computer room:
• Is large enough to hold the new array and other equipment and furniture
• Provides minimum clearance around the array for service access and to ensure proper weight
distribution on the computer 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 the locations of:
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. Interconnecting cables and power cords, including lengths
g. Floor vents
