Portion of the HPSS Core Server that provides a logical abstraction of bitfiles
to its clients.
Block Multiplexer Channel
The number of data bytes that are written to a tape virtual volume before a
tape mark is required on the physical media.
Cartridge Access Port
A physical media container, such as a tape reel or cassette, capable of being
mounted on and dismounted from a drive. A fixed disk is technically
considered to be a cartridge because it meets this definition and can be
logically mounted and dismounted.
The main repository of logged messages from all HPSS servers enabled to
send messages to the Log Daemon.
A type definition in Java. It defines a template on which objects with similar
characteristics can be built, and includes variables and methods specific to the
class.
A set of storage system characteristics used to group bitfiles with similar
logical characteristics and performance requirements together. A Class of
Service is supported by an underlying hierarchy of storage classes.
The unit of storage space allocation on HPSS disks. The smallest amount of
disk space that can be allocated from a virtual volume is a cluster. The size of
the cluster on any given disk volume is determined by the size of the smallest
storage segment that will be allocated on the volume, and other factors.
The process of initializing or modifying various parameters affecting the
behavior of an HPSS server or infrastructure service.
Class of Service
An HPSS server which manages the namespace and storage for an HPSS
system. The Core Server manages the Name Space in which files are defined,
the attributes of the files, and the storage media on which the files are stored.
The Core Server is the central server of an HPSS system. Each storage sub-
system uses exactly one Core Server.
A UNIX program that runs continuously in the background.
A relational database system, a product of IBM Corporation, used by HPSS to
store and manage HPSS system metadata.
A log record message type used to log lower-level error conditions.
Digital Equipment Corporation.
The process of extraction, formatting, and outputting HPSS central log
records.
The process of disabling notification to SSM for a particular attribute change.
A human-readable name for an HPSS server.
