cluster capacity
The total amount of disk space in a cluster, excluding the space required
for system overhead and the operating system. Cluster capacity is the
amount of space available for all archive data, including original file data,
metadata, and redundant data.
Command Control Interface (CCI)
Software used to control volume replication functionality (such as
TrueCopy or ShadowImage) by means of commands issued from a host to
a storage system. A command device must be set up in the storage
system to enable the storage system to receive commands from CCI.
In an open system, Replication Manager uses the CCI configuration
definition files to modify copy pair configurations and to acquire
configuration information. Copy pair modification processing, such as
splitting and resynchronizing copy pairs, is executed on the storage
system via CCI.
command device
A dedicated logical volume used to interface with the storage system. Can
be shared by several hosts.
