Switch and Point-to-Point Connections

You can cascade switches (connect one switch port to another switch)
for additional port connections.
Switch Zoning
Switch zoning lets an administrator define paths between connected
nodes based on the node's unique World Wide Name. Each zone
includes a server adapter and/or one or more SPs. EMC recommends
single-initiator zoning, which limits each zone to a single HBA port
(initiator). The current connection limits are outlined in Table 1-2.
