FICON configurations

NOTE

FICON configurations are available only for Fabric OS products.

IBM Fibre Connection (FICON) is a protocol used between IBM (and compatible) mainframes and storage. FICON configurations can be categorized into three types, based on complexity:

•Point-to-point configurations that do not use a switch.

•Switched point-to-point configurations, also called single switch configurations, connect a host channel to a storage control unit using a single switch. In this type of configuration, the channel is configured to use single-byte addressing.

•Cascaded configurations, also called high integrity fabrics, connect host channels and storage control units that reside in different domains. Cascaded FICON fabrics must be configured as high integrity fabrics. In this type of configuration, the channel is configured to use two-byte link addressing. Figure 250 and Figure 251 are examples of cascaded FICON configurations. IBM does not support configurations that have more than two domains in a path from a FICON Channel interface to a FICON Control Unit interface to Channel-to-Channel (CTC) except under special circumstances.
