Glossary
array A synonym of storage array, storage system, and virtual array. A group of disks
in one or more disk enclosures combined with controller software that presents
disk storage capacity as one or more virtual disks.
asynchronous A term used to describe computing models that eliminate timing dependencies
between sequential processes. In asynchronous replication, the array controller
acknowledges that data has been written at the source before the data is copied
at the destination. Asynchronous write mode is an optional DR group property.
See also synchronous.
bandwidth The transmission capacity of a link or system, usually measured in bits per second.
bidirectional An array that contains both source and destination virtual disks. A bidirectional
configuration allows multidirectional I/O flow among several arrays.
CA HP P6000 Continuous Access. A storage-based HP solution consisting of two or
more arrays performing disk-to-disk replication, along with management user
interfaces that facilitate configuring, monitoring, and maintaining the replicating
capabilities of the arrays.
CIM Common information model.
CLI Command-line interface. An interface comprised of various commands which
are used to control operating system responses.
CLX Cluster Extension.
P6000 Command
View
HP P6000 Command View consists of:
The GUI that displays the usage of the storage system.•
• The software behind the GUI, which controls and monitors the functions.
• The P6000 Command View software can be installed on more than one
management server in a fabric. Each installation of P6000 Command View
software is a management agent. The client for the agent is a standard
browser.
Continuous Access
user interface
A tool for managing the replication of storage objects in a SAN. It provides a
graphical user interface for the management of disk I/O, failover, and
maintenance operations. The Continuous Access user interface is installed on
the management server and appears as a software service.
copy set A source-destination pair of virtual disks that are members of a DR group.
data distribution Pushing copies of data to geographic locations to make it more easily accessible
to many customers.
data migration Moving data to a new location or to one with a larger capacity.
