1. A system comprising:
a target device; and a storage appliance coupled to the target device, the storage appliance including:
a network interface for receiving a request from one of a plurality of client devices to access the target device;a storage interface for accessing data from the target device; anda datapath for implementing a storage transfer protocol to facilitate transfer of data between the client device and the target device, wherein the storage appliance is defined to determine which of the client devices has access to the target device based on a password, wherein to determine which of the client devices has access to the target device, the storage appliance is configured to determine whether the request includes a name of the target device and is defined to authenticate the password within the request without determining an identity of the one of the client devices, wherein the storage appliance is further defined to allow access to the target device upon determining that the request includes the name of the target device and that the password has been authenticated and without determining the identity of the one of the client devices.
