ICP

In the CentricStor system the ICP is the interface to the host systems connected. These
are connected using ESCON, FICON or FCP.
The ICP’s principal task is to emulate the physical drives for the host systems
connected.

The predefined host names for this ISP type are ICP0, ICP1, etc.

ICP_IDP

An ICP_IDP combines the attributes of an

ICP

and those of an

IDP

: this computer has

interfaces to the hosts and to the tape drives.

The ICP_IDP is the only ISP type used in the CentricStor models VTA 500 and VTA
1000 and consequently has the attributes of a VLP.

IUP (Integrated Universal Processor) is a synonym for ICP_IDP.

The predefined host names for this ISP type are IUP0 and IUP1.
