The main window displays a circuit diagram of the CentricStor system with the ISPs, RAID
systems and the connecting Fibre Channel system.
Processors
CentricStor is a group of processors, each running the SINIX-Z operating system. These
processors are referred to collectively as the ISP (Integrated Service Processor).
Depending on the peripheral configuration and the software configuration, CentricStor
recognizes various ISP types:
ICP
IDP
ICP_IDP
VLP
SVLP
Hybrid forms are created when ISPs of the type ICP, IDP and ICP_IDP have the VLP or
SVLP functionality. In these cases the VLP or SVLP functionality is then specified in para-
entheses after their ISP names. Example: ICP_IDP (VLP)
The ISP symbol contains a large amount of information. If you click on the symbol with the
left mouse button, the status information is entered in the right-hand window area and there
constantly updated (see the
object information" on page
126
Integrated Channel Processor
ISP with a host connection via ESCON, FICON and/or FibreChannel.
Integrated Device Processor
ISP without a host adapter but with tape drives.
ICP and IDP in one ISP. An ICP_IDP has both a host adapter and a SCSI or FC
controller for running real tape drives and robots.
Virtual Library Processor
ISP with neither a host interface nor a device interface. This ISP hosts the VLM
and the PLM.
Standby VLP (optional)
The SVLP is an optional processor which can take over the tasks of the VLP if
the VLP should fail.
