The 25GbE Alliance that was initiated by Arista seems to had a fair amount of impact. The IEEE has moved faster than its usual “dead turtle” pace and actually implemented the final stage of the standards process.
Scope of the project: This amendment defines Ethernet Media Access Control (MAC) parameters, physical layer specifications, and management parameters for the transfer of Ethernet format frames at 25 Gb/s for server to switch interconnections.
One problem I have is this:
Baseline proposal of a retimed 25Gb/s PMD to address the P802.3by objective to ‘Provide physical layer specifications which support link distances of at least 100 m over MMF’
WTF is the IEEE thinking ? We don’t need 100 metres to connect devices inside a rack. 25 metres yes. But who the heck wants 100 metres ?
- You aren’t going to use 25GbE as a trunk between switches, its too slow.
- Desktops ? Don’t make me laugh, there isn’t a big enough market to want to use desktops since people are moving to tablets, laptops and smartphones on wireless.
- And desktops at at 10GbE is a dead end. There isn’t a market for 25GbE to the desktop.
Can someone go over there and give them a slap and shout “what the hell are you thinking”. Tell them to focus on the solution instead of inventing new problems.
