Glossary

3PAR Domains: A 3PAR feature that is used to create distinct domains with domain-

specific users and objects in an InServ Storage Server.

3PAR Remote Copy: A 3PAR product that allows you to copy virtual volumes from one

InServ Storage Server to another. The copy can be used for disaster recovery,

backup, or data migration.

3PAR Thin Provisioning: A 3PAR product that allows the user to allocate only the physical

resources that are actually needed while presenting an arbitrarily large volume that

can have its physical resources allocated on demand.

active VLUN: The connection of a virtual volume and a LUN for a particular host on a

particular port. An active VLUN is created when a VLUN template is applied to the

current system state. See also VLUN template.

admin space: See snapshot administration space.

admin volume: The base volume that is used by the system to store administration data

such as the system event log. The admin volume is created as part of the storage

server installation and setup process.

administration space: See snapshot administration space.

alert: A system event requiring immediate operator activity.

alert pane: The alert pane, located at the bottom of the InForm Management Console main

window, displays information about system alerts.

allocation limit: User-defined threshold that can be set for thinly provisioned virtual

volumes (TPVVs) to cap their potential size. See also allocation warning.

allocation warning: User-defined threshold that can be set for thinly provisioned virtual

volumes (TPVVs) to alert users when they reach a certain size. See also allocation

limit.

availability: Level of fault tolerance for a logical disk. For example, Magazine level

availability means that the logical disk can tolerate a drive magazine failure. Cage

availability level means that the logical disk can tolerate a drive cage failure.

backup server: In a Remote Copy setup, the storage server on which the copied volume

groups reside.

base volume: Virtual volume type that forms the root of all virtual and physical snapshot

functionality. Base volumes are the only type of volume that have snapshot data

space and snapshot administration space used by snapshots to track changes to the

base volume. See also thinly provisioned virtual volumes (TPVVs).
