General Site Preparation Guidelines Space Requirements Space Requirements This section contains information about space requirements for an HP 9000 rp4410 or HP 9000 rp4440 server installation. This data should be used as the basic guideline for space plan developments. Other factors, such as airflow, lighting, and equipment space requirements must also be considered. Delivery Space Requirements There should be enough clearance to move equipment safely from the receiving area to the computer room. Permanent obstructions, such as pillars or narrow doorways, can cause equipment damage. Delivery plans should include the possible removal of walls or doors. Operational Space Requirements Other factors must be considered along with the basic equipment dimensions. Reduced airflow around equipment causes overheating, which can lead to equipment failure. Therefore, the location and orientation of air conditioning ducts, as well as airflow direction, are important. Obstructions to equipment intake or exhaust airflow must be eliminated. The locations of lighting fixtures and utility outlets affect servicing operations. Plan equipment layout to take advantage of lighting and utility outlets. Do not forget to include clearance for opening and closing equipment doors. Clearance around the cabinets must be provided for proper cooling airflow through the equipment. If other equipment is located so that it exhausts heated air near the cooling air intakes of the server cabinets, larger space requirements are needed to keep ambient air intake to the server within the specified temperature and humidity ranges. Space planning should also include the possible addition of equipment or other changes in space requirements. Equipment layout plans should also include provisions for the following: • Channels or fixtures used for routing data cables and power cables • Access to air conditioning ducts, filters, lighting, and electrical power hardware • Power conditioning equipment • Cabinets for cleaning materials • Maintenance area and spare parts Floor Plan Grid A floor plan grid is used to plan the location of equipment in the computer room. In addition to its use for planning, the floor plan grid should also be used when planning the locations of the following items: • Air conditioning vents • Lighting fixtures • Utility outlets • Doors • Access areas for power wiring and air conditioning filters 38 Chapter 2
