[802.3_DIALOG] Call for interest - 25 Gb/s operation over a single lane

Dear Colleagues,

The following request for agenda time for a call for interest has been received from Mark Nowell. It will be discussed at the IEEE 802 LMSC July 2014 Plenary meeting in San Diego, CA USA. If you have any questions please get in touch with either Mark Nowell <mnowell@xxxxxxxxx> or myself directly.

The use of Top of Rack 4x10Gb/s breakout using 40Gb/s interfaces has become very popular over the last few years in hyper-scale data centers and cloud services providers. As these data centers prepare to transition to 100Gb/s Ethernet, there is an expectation to use the 100Gb/s 4x25Gb/s interface specified in IEEE P802.3bj and IEEE P802.3bm as effectively as is done with the 4x10Gb/s 40Gb/s Ethernet interface.  Efficient and effective data center and cloud architectures would utilize the 25Gb/s technology within the 4x25Gb/s 100Gb/s interface technology and enable breakout to single lane 25Gb/s interfaces.  At this time, there is no ability for data centers and cloud services providers to enable this network efficiency without a common specification for 25Gb/s Ethernet.  This Call For Interest is a request for the formation of a study group to 1) explore enhancements that take advantage of interfaces within IEEE P802.3bj and IEEE P802.3bm to provide a single lane 25Gb/s Ethe!
 rnet specification for server interconnects, and 2) the market requirements supporting the server-TOR application of a 25Gb/s Ethernet interface.


The call for interest will take place during the IEEE 802.3 Opening Plenary on the afternoon of Monday 14th July. A call for interest consensus building meeting will be scheduled to occur during the week. The vote to determine if a Study Group will be formed will take place at the IEEE 802.3 Closing Plenary on the afternoon of Thursday 17th July.
