Glossary
destination site
The location of the secondary network.
disaster tolerant (DT)
A solution that provides rapid data access recovery and continued data processing after the
loss of one or more components.
failback
1. The process that takes place when a previously failed controller is repaired or replaced and
reassumes the workload from a companion controller.
2. The process that takes place when the operation of a previously failed cluster group moves
from one cluster node back to its primary node.
failover
1. The process that takes place when one controller in a dual redundant configuration assumes
the workload of a failed companion controller. Failover continues until the failed controller
is repaired or replaced.

Fibre Channel over Internet Protocol (FCIP)
A method of moving Fibre Channel data over a standard Internet Protocol network.
Fibre Distributed Data Interface (FDDI)
A set of ANSI protocols for sending digital data over fiber optic cable.
hierarchical storage virtualization (HSV)
A transparent abstraction of storage at the block level. Using block-level mapping techniques,
storage virtualization presents host servers with a logical view of storage in the form of
virtual disks. All raw storage is pooled, and virtual disks (or Vdisks) are created that draw
their capacity from the pool.
high availability (HA)
Redundant systems, software, and IT processes to reduce the risk of downtime. No single
points of failure.
