As I understand it, it is still split 50/50% wise. Two active MIC slots arbitrate equally for packet processing resources, regardless of how much bandwidth they could potentially (or not) use. A 20x1G MIC will essentially "waste" 40G of throughput. Yeah. :-/ On 5 December 2014 at 19:10, Olivier Be

If you use one 10x10GE MIC and one 20x1GE, on the paper 120 Gb/s would mean no oversubscribing, but how the capacity will be really divided? > Tom Storey wrote : > > As was explained to me a while back, the MPC3E has ~120gbit of capacity. > > But the devil was in how that capcity is shared bet

As was explained to me a while back, the MPC3E has ~120gbit of capacity. But the devil was in how that capcity is shared between the two MIC slots. When you have two active MICs that capacity is divided equally between the two MICs: 50/50% or ~60/60gbps. It is NOT a case of operate one card at fu
