A method of accessing a remote storage subsystem from a host device separate from the remote storage subsystem and connected via interfaces to a data communications topology is disclosed. In one embodiment, the communications interface comprises an RDMA network fabric. In one embodiment, the method includes queuing a write command or a read command in a submission queue of the remote storage subsystem, and placing a write data into a memory of the remote storage subsystem. The method further includes transmitting a message to the remote storage subsystem indicating the write command or the read command has been submitted in the submission queue, and detecting a command completion status from a completion queue of the remote storage subsystem. The method further includes transmitting a message to the remote storage subsystem indicating the command completion status has been detected.
