SN8000B 8-Slot Director, SN8000B 4-Slot Director, DC SAN Backbone Director,
and DC04 SAN Director inter-chassis links
ICLs are optional, dedicated high-bandwidth links that connect two SN8000B SAN Directors or
DC SAN Director Switches. IBM does not count the ICL as a hop in the path between the CHPID
and CU. Therefore, three directors can be configured in the path without exceeding the maximum
hop count of one, provided two of those directors are SN8000B SAN Directors, DC SAN Directors,
or DC04 SAN Directors connected with ICLs.
Figure 11 (page 39) shows a configuration with DC Backbone Directors. A configuration using
SN8000B SAN Directors or DC04 SAN Directors would look similar.
