A bridge includes a host interface via which data/commands are received from and transferred to a host, and a storage device interface via which data/commands are received from and transferred to a storage device. The bridge also includes one SDPC, a controller and a switching system that is configurable by the controller to connect the protocol converter to the host interface and the storage device interface if the storage device protocol used by the host device differs from the storage device protocol used by the storage device, and to connect the host device interface to the storage device interface, not via the bi-directional protocol converter, if the two storage device protocols are the same. The bridge may include two SDPCs, each for converting a different protocol to the host protocol and vice versa, with the switching system being configurable to switch between the two SDPCs. The bridge may omit the SDPC altogether, with the switching system being configurable to switch between connecting (1) the host device interface to the storage device interface, and (2) bypassing the storage device interface. |
