Agent
In a client-server system, a program that performs information gathering or processing tasks
on behalf of a client or server. Agents often communicate with other agents to perform a
collective task on behalf of the user.
StorageWorks agents run on storage system host computers and can be accessed by
StorageWorks clients to control and manage the storage system.
Compaq Insight Manager Agents run on managed devices to monitor faults, performance, and
security, and to provide notification of changes in the device.
BCV

standard production unit. A BCV unit can subsequently be used in production tasks, such as
backups, application migration, data mining, and testing. A key feature of a BCV unit: the unit
can be accessed while the production volume remains online for normal I/O. The term BCV
unit does not imply the use of any specific technology.
