Connecting the Appliance to Hosts and Storage Arrays

Continuous Access Storage Appliance Installation and Maintenance Guide
Zones for back-end switches
Create zones that have one appliance initiator and one storage controller port. Storage arrays
may have one port per controller (
) or two ports per controller (
). The two
appliance initiators connect to the switches as follows:
■
From node 0:
— I1 connects to port 0 on back-end switch 1.
— I2 connects to port 1 on back-end switch 2.
■
From node 1:
— I1 connects to port 0 on back-end switch 2.
— I2 connects to port 1 on back-end switch 1.
lists the zones you create for two storage arrays (with one port per controller)
connected to the switch (a total of 28 storage zones). For each storage controller port
connected to the switch, create four zones—one for each appliance initiator (
). You
can connect a maximum of 14 storage arrays to a non–cascaded 16–port switch (two initiators
multiplied by 14 storage arrays).
