2.3. HPSS Components
The components of HPSS include files, filesets, junctions, virtual volumes, physical volumes, storage
segments, metadata, servers, infrastructure, user interfaces, a management interface, and policies.
Media and file metadata are represented by data structures that describe the attributes and
characteristics of storage system components such as files, filesets, junctions, storage segments, and
volumes. Servers are the processes that control the logic of the system and control movement of the
data. The HPSS infrastructure provides the services that are used by all the servers for operations
such as sending messages and providing reliable transaction management. User interfaces provide
several different views of HPSS to applications with different needs. The management interface
provides a way to administer and control the storage system and implement site policy.
These HPSS components are discussed below in Sections 2.3.1 through 2.3.7.
