Single Host With One Controller Unit

shows one application host connected through an FC-AL cable to one

array controller unit. The Ethernet cable connects the controller to a management
host via a LAN on a public or separate network, and requires an IP address.

Note –

This configuration is not recommended for RAS functionality because the

controller is a single point of failure. In this type of configuration, use a host-based
mirroring solution to protect data in cache.

Note –

For the Sun StorEdge T3 array, you must insert a media interface adapter

(MIA) into the FC-AL connection port on the array controller card to connect the
fiber-optic cable. This is detailed in the Sun StorEdge T3 and T3+ Array Installation,
Operation, and Service Manual.
