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 Integrated Channel Processor
ISP with a host connection via ESCON, FICON and/or FibreChannel.
IDP Integrated Device Processor
ISP without a host adapter but with tape drives.
ICP_IDP 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.
VLP Virtual Library Processor
ISP with neither a host interface nor a device interface. This ISP hosts the VLM
and the PLM.
SVLP Standby VLP (optional)
The SVLP is an optional processor which can take over the tasks of the VLP if
the VLP should fail.
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
section “ICP object information” on page 134 and section “IDP
object information” on page 135 ).
