Host Connection; Software Architecture - Fujitsu Siemens Computers pmn User Manual

Software architecture

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:
Host system
Mainframe
Open Systems
FibreChannel with ESCON or FICON connections can be operated in mixed mode on an
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.
