The XP array family supports between 1–16 GB of cache memory. In the event of
power loss, the contents of the cache boards are battery backed to survive up to 48
hours.
Common desktop environment.
Customer engineer.
Cache fast write.
Channel.
The channel adapter (CHA) provides the interface between the disk array and the
external host system. Occasionally this term is used synonymously with the term
channel host interface processor (CHIP).
Synonymous with the term channel adapter (CHA).
The processors located on the channel adapter (CHA).
Channel path identifier.
Count key data.
Cluster.
A volume on the disk array that accepts CA or BC control operations which are then
executed by the disk array.
A file that defines the pair configurations.
The group identifier for which the disk array guarantees the sequence of asynchronous
data transfer for the asynchronous CA volume group.
To organize the storage space attached to the DKC, you can group similarly configured
logical devices (LDEVs) with unique control unit images (CUs). CUs are numbered
sequentially.
The XP256 supports up to 4 CUs. The XP512/48 supports up to 16 CUs.
Each CU is able to manage up to 256 LDEVs. Therefore, to uniquely identify a
particular LDEV requires both the CU number as well as the LDEV number.
Central processing unit.
Canadian Standards Association.
Continuous Track maintenance support application.
Control unit.
Custom Volume Size (also called Virtual LVI).
A process that resides in the UNIX system and waits for events and that does not
disappear after an event is carried out.
