Chapter 2 — Site Requirements
Service Access Requirements
Minimum Access Requirements A minimum of 2 feet (0.6 m) of clearance
is required on the left and right ends of the library to provide service access
to the service frames. If data center equipment is on rolling racks and can
be easily moved to provide the clearance on each end of the library, then
having equipment adjacent to the ends of the library is acceptable. In
addition, a minimum of 2 feet (0.6 m) of clearance at the front and back of
the main frame, each drive expansion frame, and each service frame is
required for airflow and service and operator access.
The library depth is 3.6 feet (1.1 m). The depth for the library main frame,
each drive expansion frame, and each service frame plus the 2 feet (0.6 m)
of required access space front and back is 7.6 feet (2.3 m).
Recommended Access Requirements Providing 3 feet (0.9 m) of clearance
on all sides of the library is recommended.
The library depth is 3.6 feet (1.1 m). The depth for the library main frame,
each drive expansion frame, and each service frame plus the 3 feet (0.9 m)
of recommended access space front and back is 9.6 feet (2.9 m).
The following table shows the width requirements for multi-frame
libraries plus the minimum and recommended access space on each side of
the library. For libraries greater than ten frames, add 2.42 ft. (0.74 m) for
each additional frame.
