Scott, I would agree with your summary. Even though 802.1Qbg/Qbh started about six/seven years ago, it’s clear that networking needed to become more dynamic and exchange status and configuration with the server.

—- excerpt from draft standard 802.1Qbh
Need for Project
——————-

Data center management today is highly complex. This complexity may be reduced by aggregating the more complex bridging functions onto fewer bridges and by collapsing bridge layers from a management perspective. The EVB project is defining reflective relay and multichannel capabilities. The Port Extension project extends these capabilities by providing a remote replication service. In addition, a Port Extender device will be specified that utilizes the EVB capabilities and remote replication service. This is intended to reduce management complexity by aggregating the more complex bridging functions onto fewer bridges.

The Port Extender device may be used to collapse layers in the network resulting in reduced capital expenditure, points of management, and management traffic and thus reducing total cost of ownership.

So what VAAI has done to simplify the use of storage arrays for many use cases, I believe that 802.1Qbh could achieve same for networking. That is, more complex network connections are made easier to use by a new technology by “hiding” the hard parts such as getting configuration in sync between server and network, exposing the status and performance of server to network, and network to server.
