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
