Brocade encryption solution overview

Data flow from server to storage
The Brocade encryption switch can be introduced into a SAN with minimum disruption, with no
need for SAN reconfiguration, and with no need to reconfigure host applications. Frames sent from
a host and a target LUN are redirected to a virtual target associated with the encryption switch. The
encryption switch then acts as a virtual initiator to forward the frames to the target LUN.
