FICON support for multiple-hop cascaded SAN configurations
Before the introduction of the z13 and z13s servers, z Systems FICON SAN configurations
only supported a single ISL (or single hop) in a cascaded FICON SAN environment. IBM
z13s servers now support up to three hops in a cascaded FICON SAN environment. This
support allows you to more easily configure a three or four site disaster recovery solution.
FICON feature summary
Table 4-9 shows the FICON card feature codes, cable type, maximum unrepeated distance,
and the link data rate on a z13s server. All FICON features use LC Duplex connectors.
