Pardon my ignorance once again, but is this showstopper bad?  The 
me3800x appears to have 352MB, so clearly a lot more, but IIRC older 
switches like the 3560 had something like 2MB per ASIC. I'm assuming one 
of the main reasons for buffers on a unit like this is the speed 
disparity between 10ge and 1ge ports, unless you're planning to do a lot 
of shaping (rather than policing) - is this correct?


Thanks,
