Creating zones for the switches
This section describes a configuration in which two switches connect to the front end of the
appliance and two switches connect to the back end of the appliance, enabling failover and
recovery (See
.) This configuration allows multiple host connections
on the front end and multiple storage connections on the back end.
This section describes the following topics:

Zones for front-end switches
Create zones that have one host initiator and one appliance target. The six appliance targets
connect to the first six ports on the switch (0–5). For each host initiator connected to the switch
(ports 6 and 7 on the switch), create six zones—one for each appliance target (
).
lists the zones you create for two hosts connected to the switch (a total of 12 zones).
The appliance target use six ports on the switch; you can use the remaining 10 ports for host
connections. You can connect a maximum of 10 hosts to a non–cascaded 16–port switch,
creating 60 host zones (six targets multiplied by 10 hosts).
