3 Structural/Environmental Considerations Consider the following when choosing or designing your facilities for the storage system: • 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 for help with analyzing the site location and environment to make appropriate recommendations. For information on rack requirements and considerations, see the Best practices for HP Intelligent Series Rack Family white paper. Establishing the Proper Foundation Weight and Pressure Loads Depending on the configuration, a storage system weighs up to 2000 lb (907 kg). The following table lists the maximum weights and pressure loads per leveling foot for storage system racks. Use these values to approximate the structural support required by a storage system rack.

Anchoring Dimensions Some installations may require the storage systems to be anchored to the floor for better stability, especially in seismically active locations. The HP Tie Down Option Kit enables you to anchor an Intelligent Series Rack to the floor in geographical areas that are prone to seismic activity, thereby meeting international building code guidelines. This product provides a solution to help avoid damage or serious injury in the event of building or floor movement. 18 Structural/Environmental Considerations
