Integrated Universal Processor:
Acts as universal ICP/IDP/VLP for the CentricStor
Performs the data link to the connected host systems. Channels (mixed possible):
•ESCON / Type S
•Fibre Channel
•FICON (not for
ESCON: Enterprise Systems CONnection is the fibre optic connection for IBM mainframes
Type S: Fujitsu Siemens Computers mainframe fibre optic connection
FICON: Fiber Connection, IBM’s fiber optic channel technology that extends the capabilities of its ESCON standard.
Integrated Device Processor: Performs the data transfer to the physical tape drives. Typical 1 / maximal 8 physical tape drives per channel:
•SCSI (direct / daisy chain)
•Fibre Channel (direct / via Switch) Virtual Library Processor:
Performs the central management processes Virtual Drive Replication
Tape Volume Cache
Average data throughput from/to the host during read and write access
It is not possible to configure all components with their maximum in one system.
