Estimating Required Floor Load Rating; Floor Covering Requirements; Floor Clearance And Cutout Requirements - HP StorageWorks XP10000 - Disk Array Manual

• Use a raised floor system (254 to 305 mm, 10 to 12 inches) for the most favorable room air
distribution system.
• Grid panels must be at least 450 x 450 mm (17.72 x 17.72 in).
• The floor must have a load rating between 300 and 500 kg per square meter (553 to 921.7 lb
per square yard, or 61.4 to 102.4 lb per square foot). The maximum floor loading at any point
is 500 kg (1102.3 lb).

Estimating required floor load rating

To estimate the required load rating for your floor, consider the total weight of all of these items:
• The disk array (see
• 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 and cutout

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.

Floor clearance and cutout requirements

Figures on the following pages show the clearance dimensions, locations of floor cutouts, and other
dimensions for primary and secondary racks.
NOTE:
The top of each rack has a hole with a sliding cover for overhead cable drops. The hole is located in the
left rear corner of the rack. You can feed cables to the rack from overhead or from underneath through a
floor cutout in a raised floor (described below). Important: The top cabling hole must not be used for power
cabling.
