Glossary
access group | See array virtual port. |
active zone set | The zone set that is currently enforced on a Fibre Channel fabric. Only one zone |
| set can be active for a fabric at a given time. See also zone set. |
addressable storage | See LUN storage. |
addressable unit | Any storage resource in the network that is ready to be allocated for use by hosts |
| and applications. Also called AddrUnit or AU. See also LUN. |
Agent | See managed host |
aggregate | A manageable unit of |
| consisting of one or two plexes and containing one traditional volume or multiple |
| FlexVol volumes. See also volume. |
Alarm Service | See CommandCentral Storage Alarm Service. |
alert | One of several types of configurable notifications produced when a |
| CommandCentral Storage Alert Manager alarm is triggered. Every alert in |
| CommandCentral Storage is dynamic, resetting itself automatically when a |
| condition monitored by a policy returns to its specified CLEAR state. |
Alert Manager | See CommandCentral Storage Alert Manager |
allocated storage | The total amount of addressable storage in LUNs that is designated for use by |
| specific hosts. A LUN is considered allocated when a host operating system has |
| written a device handle for the LUN (in other words, claimed the LUN) or when |
| the array has masked the LUN to a specific target. Contrast with unallocated |
| storage. |
application | A program or group of programs designed to perform a specific task. Oracle |
| Database and Veritas NetBackup are examples of applications. |
arbitrated loop | A topology for Fibre Channel networks in which nodes are connected in a single |
| logical loop or ring created by tying the transmit lead of one node loop port to the |
| receive lead of its downstream neighbor. There are primarily two types of |
| arbitrated |
| SAN fabric. A private loop is a |
| attachment. |
array | See storage array. |
array host group | See array virtual port. |
