Re: [HSSG] 40G MAC Rate Discussion



I completely agree with you that we have to get moving on 100G ASAP, but we also need a platform to move the data or else history will repeat it’s self as with 10G, where in the beginning, there was no platform to handle 10G and only with the introduction of PCIe, 10G started taking off. 


To handle 100G we need PCIe GEN 3 and that’s a long ways out. PCIe GEN 2 will be a nice fit for 40G and that’s why we are proposing an additional 40G step on our way to 100G.

Good point. The end users are already saying we’re behind schedule for 100GbE, and are giving us the impression that they will buy 100GbE as soon as products become available. There will be a time frame of probably a few years before HSSG becomes a task force, for the task force to draft out the standard, and for the draft to go through IEEE approval. By then, I believe many applications will require 100GbE.

Thomas (and others),

Those end users who have posted to the mailing list are saying that we won't buy 40GE because we don't need it, and that 10GE (frankly 1GE) is all we'll need for our servers. I'm sure there are a few specific applications for greater than 10GE to a single server, but it is NOT for those of us running really large INTERNET data centers. I would still love to hear from end users requesting 40GE, since there are several of us requesting 100GE.

The only end users we've seen send information to the thread have been saying, stop wasting time fiddling with 40GE and get to where the real needs are... 100GE for switch->router and router->router links. We'll buy those as SOON as they can be fielded.

As for folks who have CFOs (or even CIO/CTOs) telling them what to buy, I strongly suggest you look for an employer where you have a say in technology adoption because there are lots of companies that do respect their internal experts and don't just buy what vendors put in front of them.

Because I know that the CFO will override the desires of engineering
and buy the 40 Gig solution if it is cheaper. So there you have it 40 Gig
guys,  just focus on schedule and value and you will succeed!
