For information on setting up zoning, see the SAN Switch Zoning
documentation that is provided with the switch.
6.6 Cascaded Switches
Multiple switches may be connected to each other to form a network of
switches, or cascaded switches.
A cascaded switch configuration, which allows for network failures up to and
including the switch without losing a data path to a SAN connected node,
is called a mesh or meshed fabric. Figure 6–12 shows an example meshed
fabric with three cascaded switches. This is not a no-single-point-of-failure
(NSPOF) configuration.
