IBM TotalStorage SAN Volume Controller: Installation Guide
See redundant array of independent disks.
The ability of a system to continue to return data even if a component fails.
See storage area network.
See Small Computer Systems Interface.
A standard hardware interface that enables a variety of peripheral devices
to communicate with one another.
A network whose primary purpose is the transfer of data between computer
systems and storage elements and among storage elements. A SAN
consists of a communication infrastructure, which provides physical
connections, and a management layer, which organizes the connections,
storage elements, and computer systems so that data transfer is secure
and robust. (S)
An IBM pseudo device driver designed to support the multipath
configuration environments in IBM products.
A device connected between a computer and its power source that protects
the computer against blackouts, brownouts, and power surges. The
uninterruptible power supply contains a power sensor to monitor the supply
and a battery to provide power until an orderly shutdown of the system can
be performed.
A configuration that is supported.
In SAN Volume Controller, a device that host systems attached to the
storage area network (SAN) recognize as a Small Computer System
Interface (SCSI) disk.
In the storage industry, a concept in which a pool of storage is created that
contains several disk subsystems. The subsystems can be from various
vendors. The pool can be split into virtual disks that are visible to the host
systems that use them.
Physical storage that has virtualization techniques applied to it by a
virtualization engine.
