    Posted Jul 10, 2019 09:48 AM

    Hi guys,

    How ı can calculate stacking bandwidth on arubaos family?
    For example: 2930F 5510 5400

    Thank you

    All three Switch series you mentioned can form a Logical Stack (using VSF on Aruba 2930F and Aruba 5400R zl2, using IRF on HPE 5510) using frontplane (generally involving one or more 1G, 10G, 40G or 100G ports)...so your question lacks of detail.

    What are you trying to understand? Are you trying to understand the maximum VSF/IRF logical port throughput?

    Hi parnassus,

    Just I want competetive different brand's. I want learn, how can ı calculate. because Cisco's datasheet has stacking bandwidth. You can see below. But that information doesn't write our documentation

    https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-3850-series-switches/white-paper-c11-734429.html

    5406  support 2 device on vsf  with 40G
    2930F support 8 device on vsf with 10G
    3810   support 10 device on Backplane stack witch special stack cable.


    Pleace can you help me?

    VSF deployed on two Aruba 5400R zl2 can be deployed with VSF Port (chain topology) with up to eight 40Gbps physical links (or up to eight 10Gbps physical links)...so I would say that you will end up, at maximum, with an 320Gbps/80Gbps VSF Port throughput.

     

    Aruba 2930F doesn't support 40Gbps so VSF Port is limited to up to eight 10Gbps physical links (see above for throughput).

     

    Aruba 3810M supports Backplane Stacking, correct:

     

    • Stack port throughput: up to 40Gbps
    • Stack module throughput: up to 160Gbps

    According to this switching capacity, is it true? multiply Switch's support stack uplink numbers?

    2930F jl254A 4x10G = 80 Gb 
    2930M = 80 Gb
