HP StorageWorks XP24000 Disk Array Site Preparation Guide, v01 (AE131-96002, June 2007)

Space planning requirements
Space planning requires making sure your computer room:
• Is large enough to hold the new array and other equipment and furniture
• Provides minimum clearance around the array for service access and weight distribution on the
floor
• Includes correctly positioned floor cutouts for feeding power and data cables through the floor to
the array
The space planning process
1. Document your computer room's existing floor plan, including the locations of:
• Immovable objects, such as structural support columns
• Walls
• All equipment, furniture, cabinets, data communication equipment, and systems
• Floor cutouts
• Electrical outlets
• Interconnecting cables and power cords, including lengths
• Floor vents
2. Develop a new floor plan that includes the locations of:
• Immovable objects from your existing floor plan
• Walls
• The array with required clearance; see “Floor clearance” on page 27
• All other equipment, furniture, cabinets, data communication equipment, and systems
• Floor cutouts
• Electrical outlets
• Interconnecting cables and power cords (keep cables away from traffic areas to help prevent
accidents and equipment failures)
• Floor vents
• Enough space and lighting for people to work effectively on a daily basis and for periodic
equipment servicing
• Flexibility to accommodate additional equipment as your requirements increase
3. Implement the new floor plan, leaving empty space where the array will be installed. If the new
floor plan requires construction changes, consult with local contractors and your HP representatives.
Floor clearance
The total floor clearance required for the disk array includes:
• The actual space required by the equipment.
• Service clearance — the floor space required to access the disk array. Never use this space for
storage.
• Additional space required to properly distribute the equipment weight on your computer room's
raised floor. The amount of additional space required depends on your floor load rating.
To determine the floor clearance required for your disk array configuration:
1. Refer to the following five diagrams and select the appropriate one for your array configuration:
