Software architecture CentricStor - Virtual Tape Library
This SAN-based design means that each CentricStor component is in a position to access
the TVC.
2.2.5 Host connection
The host connection on the ICP is implemented using the following connection
technologies:
FibreChannel with ESCON or FICON connections can be operated in mixed mode on an
ICP.
CAUTION!
Simultaneous operation of ESCON and FICON connections is not permitted on the
same ICP.
2.3 Software architecture
The functions VLP, ICP and IDP which are described in the following sections are not
necessarily separate hardware components.
In large CentricStor configurations (VTA 1500-5000) all functions are normally implemented
in separate hardware components. In smaller hardware configurations (VTA 500/1000,
VTC, SBU), several of these functions are implemented on one hardware component. In the
VTC all functions, including the RAID system, are combined in a hardware component.
If, for example, an ICP is designated an Integrated Channel Processor, this is to be under-
stood as a function and not as a hardware component.
