Planning For Power Requirements - IBM DS8900F Introduction And Planning Manual

For DS8000 series, technical service representatives must open the front and rear covers to service the
storage system. Figure 11 on page 93 illustrates related service clearance requirements:
• For the rear of the storage system 1 , allow a minimum of 76.2 cm (30.0 in.) for the service clearance.
• The length of the tailgate opening 2 on the storage system.
• For a single storage system installation (from the front of the storage system), allow a minimum of
60.96 cm (24.0 in.) on the right side 3 in the aisle to the front of the machine.
• For the front of the storage system 4 , allow a minimum of 121.9 cm (48.0 in.) for the service clearance.
• The leveling pads 5 and 6 on the storage system.
• The opening of the tailgate 7 on the storage system.
Unlike weight distribution areas that are required to handle floor loading, keep in mind that service
clearances of adjacent unrelated storage systems can overlap.
Note: The terms service clearance and weight distribution area are often confused with each other. The
service clearance is the area that is required to open the service covers and to pull out components for
servicing. The weight distribution area is the area that is required to distribute the weight of the storage
system.

Planning for power requirements

You must select a storage system location that meets specific power requirements.
When you consider the storage system location, consider the following issues:
