My LAG is bigger than your LAG....

The Arista 7500E can have up to 64 member links in a LAG.  MLAG two of them together, and that's a port-channel consisting of 128 links.  Why you would want to do this - I don't know.  But that's one fat pipe. XD

My Virtual/Storage guy would absolutely love that.

What's the speed on each port? I have an Oracle guy that's interested in maximum throughput.

Saw the Cisco 9K can also handle this number.

If Im not mistaken isnt this a feature of the Trident 2?

Not that it's a big deal, but do you have a document that supports this?  The 9500 data sheet says 32 max, which would make for 64 in a vPC pair I'd imagine.

The 7500E is an Arad-based platform.  Not Trident.  But yes, I didn't think about it before and had to look back at my notes and T2 can support up to 64.

Speed isn't really a limiting factor here.  To my knowledge its the # of bits that can be used to hash across a number of member links.  So on the 7500 it's 10/40/100G - up to physical port count limitations of course.

Please make them all 100G, thank you. Having 12800G of throughput sounds like it will keep the Oracle guys happy... for a week... :developers:

I am going mostly off memory and didnt have a way to look it up as I was on the run. Yeah the 64 on the 9K could have been from a pair. Honestly I have heard so many product briefings in the past several months and all the CCIE studies, shit is starting to blend together.

Ill dig and look.

I actually typed Orable and then corrected it.

Now I realize that, since it rhymes with "horrible" and sounds like the British "orrible", I should have left it that way.

Interesting statement.  Why do you feel that way?  Does that include between ToR and host?
