Another first, the organization reports, was the construction and demonstration of an end-to-end DCB network via the IEEE 802.1Q standard Data Center Bridging Exchange (DCBX), a discovery and initialization protocol that discovers the resources connected to the DCB cloud and establishes its limits. The plugfest also included monitoring of the IEEE 802.1Qbb Priority Flow Control (PFC) behaviors, the part of the standard aimed at establishing priorities for flow control based to enable control over individual data flows on shared lossless links.
The Ethernet Alliance says the latest plugfest sets the stage for implementation. In a prepared statement, Joy Jiang of JDSU, chair of the DCB Plugfest, said, “DCB is enabling the convergence of traditional Ethernet and storage traffic on one, lossless Ethernet cable. This interoperability testing confirms that the standards are complete and we have products that create an eco-system of solutions that are ready to be deployed."
