IBM System Storage SAN Volume Controller: Hardware Installation Guide
In SAN Volume Controller, the set of nodes that are operating together to
deliver storage services.
The ratio of the sum of the traffic that is on the initiator N-node
connections to the traffic that is on the most heavily loaded interswitch
links (ISLs), where more than one ISL is connected in parallel between
these switches. This definition assumes a symmetrical network and a
specific workload that is applied equally from all initiators and sent
equally to all targets. See also symmetrical network.
IBM definition: A logical division of storage on a fixed disk.
HP definition: A logical division of a container represented to the host as a
logical unit.
The other node that is in the I/O group to which this node belongs.
In Metro or Global Mirror operations, the relationship between two
clusters. In a cluster partnership, one cluster is defined as the local cluster
and the other cluster as the remote cluster.
In SAN Volume Controller, the process by which the cache component
quiesces all ongoing I/O activity below the cache layer.
To cause to wait for an event.
In decimal notation, 1 125 899 906 842 624 bytes.
See power distribution unit.
The instantaneous copy that the FlashCopy service makes of the source
virtual disk (VDisk). In some contexts, this copy is known as a T
The physical entity within a host, SAN Volume Controller, or disk
controller system that performs the data communication (transmitting and
receiving) over the fibre channel.
An identifier associated with a port.
A device that distributes electrical power to multiple devices in the rack. It
typically is rack-mounted and provides circuit breakers and transient
voltage suppression.
A diagnostic test that servers or computers run when they are turned on.
In a Global Mirror relationship, the state that occurs when the mapping is
ready to start. While in this state, the target virtual disk (VDisk) is offline.
