Capacity
The amount of data storage space available on a physical storage device, usually measured in bytes
(MB, GB, TB, etc).
Channel (CH)
Description 1: A path along which signals can be sent; for example, data channel and output channel.
CHA
Channel adapter. A device that provides the interface between the array and the external host
system. Occasionally, this term is used synonymously with the term channel host interface processor
(CHIP).
CHP
Channel processor. The processors located on the CHA. Synonymous with CHIP.
CHIP
Channel host interface processor. Synonymous with the term CHA.
Command Line User Interface (CLUI)
In addition to its GUI, HPE XP7 Performance Advisor also provides a command-line utility called the
CLUI to monitor real-time performance of the XP and the XP7 disk arrays. The CLUI allows you to
monitor performance, set alarms, and configure host information using commands and scripts. You
can execute commands in the CLUI and view the same data that is displayed on the GUI. The CLUI
utility is operating system specific and can be installed locally on the management station, or remotely
on a client system.
Consistency Group ID (CTG)
A Group ID which guarantees consistency in the sequence of asynchronous data transfers for a
remote copy volume group.
Command View (CV)
Replaced by the Command View Advanced Edition Suite Software.
Command View AE (CV AE)
The Command View Advanced Edition Suite Software replaces the XP Command View Software to
manage the XP and XP7 disk arrays.
Continuous Access Synchronous (Cnt Ac-S)
The Continuous Access Synchronous Software provides remote replication between the disk arrays
that belong to the P9500/XP7 and the XP families.
Continuous Access Journal (Cnt Ac-J)
The Continuous Access Journal Software is an asynchronous mirroring program similar to the
Continuous Access Asynchronous, except that the transactions to be written to the secondary disk
array are maintained in a disk-based journal file. This provides better performance for the secondary
disk array systems that are not highly available or that may be subject to bandwidth contention from
other applications.
Copy pair
A pair of volumes in which one volume contains original data and the other volume contains the copy
of the original. Copy operations can be synchronous or asynchronous, and the volumes of the copy
pair can be located in the same storage system (local copy) or in different storage systems (remote
copy).
A copy pair can also be called a volume pair, or just pair.
