HP 3PAR StoreServ 10000 Storage Physical Planning Manual

3 Structural/Environmental Considerations
Consider the following when choosing or designing your facilities for HP 3PAR Storage Systems:
• Equipment location and layout that allows efficient use, easy maintenance, and future
expansion.
• Facility construction that provides a suitable operating environment, sufficient power and
adequate protection from fire, contamination, or other hazards.
• Suitable temperatures and appropriate air quality that is free from environmental contaminants.
The customer is responsible for maintaining the room environment according to the recommended
specifications. Environmental conditions for the room and under the floor must be maintained within
the acceptable limits to prevent any adverse impact on performance and reliability. The installation
environment should be monitored on a regular basis to ensure continued conformance to
recommended environmental specifications. The customer may request assistance from an HP 3PAR
representative to help in analyzing the site location and environment to make appropriate
recommendations.
Establishing the Proper Foundation
As with any electronic equipment that generates heat, the HP 3PAR Storage systems must be housed
in a cool environment. Common techniques for maintaining an optimal operating environment
generally incorporate the use of raised flooring and alternating hot and cold aisle layouts.
Benefits of Raised Floors
While not required, storage systems can be installed on raised floors with under the floor air
cooling. Raised floors will allow cables to be located safely beneath the floor. If the facility does
not have raised floors and under the floor air cooling, temperature and airflow must be in
compliance with the recommended specifications.
The raised floor system should consist of removable panels or panels on a stringer grid system,
supported by adjustable steel pedestal assemblies. The raised floor can be constructed of steel,
aluminum, or fire-retardant wood. The purpose of the raised floor system is to:
• Permit space between floors to supply cooled air to the equipment.
• Support the total weight of the system and service area loading.
• Protect interconnecting cables and power receptacles.
• Allow for future layout changes with minimum cost.
• Provide safety for personnel.
Raised Floor Requirements
There are additional structural considerations when installing storage systems in environments with
raised flooring.
NOTE: This section assumes a standard raised floor construction consisting of the following: 24
in. (61 cm) square or 24 in. (61 cm) X 36- in. (91.5 cm) panels, steel or aluminum stringers, and
pedestal supports attached to an underlying concrete slab or steel deck.
Prior to installation, verify the raised flooring at the operating site meets the specifications described
in Table 3 (page 18).
