A control program for a computer that
allocates computer resources, schedules tasks, and provides the

present a different personality, capacity, or both to a host. It is a
representation of real physical elements, combined to create a
grouping that is different from the physical library. Also a logical
portion of the physical library that is viewed by the host as if it is
a complete library. Partitions present the appearance of
multiple, separate libraries for purposes of file management,
access by multiple users, or dedication to one or more host
application.

S
SAN (Storage Area Network)
A dedicated network that connects
storage devices and servers in a pool, providing consolidated

(initiators).

A set of standards for a
high-speed, parallel interface that connects processing devices
