Abstract
A conventional serial communications protocol that is limited to supporting only host-to-slave communications, such as SATA or SAS, is extended to support peer-to-peer communications, e.g., by adding a memory-map layer into the conventional protocol stack between the link layer and the protocol layer. The addition of the memory-map layer enables two (or more) non-host devices (i.e., peer devices) to communicate with one another without using a host computer and without relying on conventional protocol-bridging techniques.
