HP P6000 Replication Solutions Manager User Guide (T3680-96089, October 2012)

event Any significant change in the state of the Enterprise storage system hardware or software
component reported by the controller to HP P6000 Command View.
F
fabric A network of Fibre Channel switches or hubs and other devices.
failover An operation that reverses replication direction so that the destination becomes the source and
the source becomes the destination. Failovers can be planned or unplanned and can occur
between DR groups, managed sets, fabrics or paths, and array controllers.
failsafe A safe state that devices automatically enter after a malfunction. Failsafe DR groups stop accepting
host input and stop logging write history if a group member becomes unavailable.
fast copy The process for quickly synchronizing the data on a source virtual disk and a destination virtual
disk by coping only data blocks that have changed. As I/O is written to the write history log, a
bitmap tracks the region of the virtual disk written. Only the regions that are indicated by the
corresponding bit in the bitmap are copied to the destination virtual disk. This process synchronizes
the source and destination virtual disks faster than a full copy.
full copy The process of copying all data written on a source virtual disk directly to the destination virtual
disk. If a data block contains all zeros, a zeroing message is sent to the destination array's virtual
disk for the corresponding data block. This minimizes the amount of data that must be written to
the destination virtual disk. When the full copy is complete, the source and destination virtual
disks contain the same data (synchronized).
G
GBIC Gigabit interface converter. A hardware module that connects fiber optic cables to a device and
converts electrical signals to optical signals.
GBps Gigabytes per second. A measurement of the rate at which the transfer of bytes of data occurs.
A GBps is a transfer rate of 1,000,000,000 (109) bytes per second.
Gbps Gigabits per second. A measurement of the rate at which the transfer of bits of data occurs.
Nominally, a Gb is a transfer rate of 1,000,000,000 (10
9
) bits per second.
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 A 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 The storage capacity that is defined and mountable by a host operating system.
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.
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.
