Floor loading

In addition to the minimum clearance required for servicing, the computer

room floor may need additional clearance and requires proper construction

to support the total weight of the equipment as well as the localized weight

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. The weight should be spread evenly and the

flooring should provide an area through which interconnecting cables can

be run conveniently and unobtrusively. It should allow for optimum

distribution of conditioned air. Raised floor access ramps must not exceed a

° slope.

To estimate floor strength, the following items should be considered:

• The total weight of the equipment (the unpackaged and packaged

weights are listed in this chapter)

• The total weight of furniture such as desks, chairs, and storage

cabinets

• Total approximate weight of computer room personnel

• Weight of moving equipment such as forklifts, dollies, and so on.

Any questions regarding the adequacy of airflow construction should be

referred to and evaluated by a qualified structural engineer.

Caution In addition to determining the adequacy of the computer site floor, ensure

that all floors, stairs, and elevators which might be used when the disk

array is moved to its destination can support the weight and size of the

equipment. Failure to comply can result in damage to the equipment.

Maximum point floor loading is 500 kg (1102.3 lb).
