Re: [H/W] nexus 6k released... said by HELLFIRE:Dafaq are you moving through the chassis that needs 40Gbe uplinks?!?
dense compute environments (cisco ucs, et al) all attached to a single pair of n5k.
at this point -- the n5k is a tough balancing act. you want high-speed, line-rate, cut through switching to provide optimum performance to your compute pods -- but in order to support the density -- you need to have additional uplinks which takes away your ability to have "a bunch of servers" off the n5k.
with technologies like fc-multihop becoming realities, its not just pure ethernet frames running over the wire. you'll need to support your converged infrastructure back to the aggregation tier -- meaning higher throughput rates to support losses fc and highspeed ethernet on the same wire.
And to answer my favorite question about the buffer architecture...
do the math on how many microseconds 16meg is at a full 40gb/s. these buffers are 'skid' buffers at best -- especially on egress.
