Minimum configuration

When using a single FICON® Director, the minimum number of shared FC channels required to allow any partition to communicate with any other partition is:

FC channels = M
        where M = number of processor complexes

For unspanned FC channels that are shared on a processor complex that supports multiple logical channel subsystems, the value M above is equal to the total number of logical channel subsystems on the processor complexes.

When using a single FICON Director, the minimum number of unshared FC channels required to allow any partition to communicate with any other partition is:

FC channels = n
        where n = number of processor complexes in basic mode
               or number of logical partitions in LPAR mode
