HP P6000 Continuous Access Implementation Guide (T3680-96431, August 2012)

general-purpose
server
A server that runs customer applications such as file and print services. HP P6000 Command
View and HP P6000 Replication Solutions Manager can be used on a general purpose server
in limited configurations.
H
home The DR group that is the preferred source in a replication relationship. By default, home is the
original source, but it can be set to the destination DR group.
host A computer that runs user applications and uses the information stored on an array.
host volume Storage capacity that is defined and mountable by a host operating system.
I
initialization A configuration step that binds the controllers together and establishes preliminary data structures
on the array. Initialization also sets up the first disk group, called the default disk group, and
makes the array ready for use.
intersite link A connection from an E-Port on a local switch to an E-Port on a remote switch.
ISL Intersite link.
IVR Inter-VSAN Routing
M
managed set Selected resources grouped together for convenient management. For example, you can create
a managed set to manage all DR groups whose sources reside in the same rack.
management
server
A server on which HP Enterprise Virtual Array (EVA) management software is installed, such as
HP P6000 Command View and HP P6000 Replication Solutions Manager.
merge The act of transferring the contents of the write history log contents to the destination virtual disk
to synchronize the source and destination.
mirrorclone Mirrorclone replication establishes and maintains a copy of an original virtual disk via a local
replication link.When first created (and whenever resynchronized by an action or command), a
mirrorclone is said to be synchronized. In a synchronized state, the mirrorclone is automatically
updated whenever the source virtual disk is updated. When local replication between a
synchronized mirrorclone and the source is stopped by an action or command, the mirrorclone
is said to be fractured. In a fractured state, the mirrorclone is not updated when the source virtual
disk is updated. At the instant replication is stopped, the mirrorclone is a point-in-time copy of its
source.
N
nearline storage On-site storage of data on media that takes only slightly longer to access than online storage
kept on high-speed disk drives.
normalization The background process of copying the contents of a source virtual disk to a snapclone. The
snapclone is dependent on the source until normalization is complete. Also called unsharing.
O
online storage An allotment of storage space that is available for immediate use, such as a peripheral device
that is turned on and connected to a server.
P
presentation The array controller's act of making a virtual disk accessible to a host computer.
R
remote copy A copy of a virtual disk on the destination array.
RPO Recovery Point Objective. The maximum age of the data you want the ability to restore in the
event of a disaster. For example, if your RPO is 6 hours, you want to be able to restore systems
