VLP (Virtual Library Processor)
The VLP is responsible for the coordination of the entire CentricStor system. Although the
software can be activated on any of the ICP or IDP systems, it is recommended for perfor-
mance reasons that you either provide a separate VLP, or activate the components of the
VLP on one of the IDPs, since the CPU utilization is at its lowest here.
The use of a second VLP (SVLP) is optionally possible.
1 VJUK runs on an ICP.
