    Hi guys

    What is the difference between system switching Capacity and Model Switching Capacity?

    Hi, in my opinion that table is quite confusing.

    Model Switching Capacity means that - for a particular model - its Switching Capacity is equal to the stated value (you see: 880 Gbps for JL658A and JL659A, 640 Gbps for JL660A and 496 Gbps for JL661A).

    System Switching Capacity instead is only a way to state that the whole Aruba 6300M Switch Series (as a family) reaches that maximum value - 880 Gbps.

    At least this is what I understood at first sight.

    Example:

    JL661A has 48 1Gbps ports + 4 50Gbps ports so: (48 x 1000 x 2 = 96 Gbps) + (4 x 50000 x 2 = 400 Gbps) = 496 Gbps

    But Aruba states that the family (clearly considering other models) reaches 880 Gbps...this information is - IMHO - useless: I mean, I'm interested in understanding what Switching Capacity has a particular model, not the entire family generically.

    Hi,

    just guessing here as well but from my point of view, all switches in one family have the same ASIC which is, in the case of the example above, capable of 880Gbps. But due to the port configuration, not all models are capable of using the available bandwidth. The calculation from  @parnassus shows a great example of this. 

    just my 2cents

    Hi Florian, yeah exactly the meaning was that one: the HPE 7th Generation ProVision ASIC employed into Aruba 6300M Switch Series, is able to deliver 880 Gbps of (full duplex, non blocking) total throughput.
