The SAN configuration page lets you connect your appliance to your SAN (Storage Area Network). A SAN is made up of three basic components:
A client which will access the storage on the network
A storage appliance which will provide the storage on the network
A network to link the client to the storage
These three components remain the same regardless of which protocol is used on the network. In some cases, the network may even be a cable between the initiator and the target, but in most cases, there is some type of switching involved.
