    Hello all

    i am looking for a new switch to connect my ESX with 10gb
    the switch will be connected via uplinks of 10 gb SFP to my BB
    i need RJ45 10gig ports to connect my esx server 

    what will be better ?
    HP 5945
    Arube 6300M
    Arube 2930 

    i need at least 12 RJ45 10 gig ports and 2 sfp+ 10 gig for uplink

    thanks

    Hello Tzvika, as ToR the Aruba 6300M (or 6300F) and Aruba 2930M (or 2930F) Switch series don't support front-plane Ethernet ports running at 10Gbps like, as example, the HPE FlexFabric 5940 (or the newer HPE 5944). I believe the HPE FlexFabric 5945 Switch series hasn't a model natively supporting front-plane 10GbE copper ports.

    Despite they are all really overkill for just connecting few RJ45 ports (12 or 24, it doesn't matter) at 10Gbps speed, these could fit your requirements:

    Aruba CX 8360 48XT4C Bundle (JL706A/JL707A) <- probably overkill 48x10GBase-T ports + 4x100Gb QSFP ports (the bundle already includes 3 Port-to-Power Fans and 2 Port-to-Power Power Supply units (JL706A) or, alternatively, 3 Power-to-Port Fans and 2 Power-to-Port Power Units (JL707A))
    Aruba CX 8320 (JL581A) <- probably overkill 48x10GBase-T ports + 6x40G QSFP+ ports (the bundle already includes 5 Port-to-Power Fans and 2 Port-to-Power Power Supply units)
    HPE FlexFabric 5710 48XGT 6QS+/2QS28 Switch (JL586A) <- pretty reasonable! 48 XGT ports
    HPE FlexFabric 5710 24XGT 6QS+/2QS28 Switch (JL689A) <- pretty reasonable! 24 XGT ports

    HPE FlexFabric 5940 48XGT 6QSFP+ Switch (JH394A) <- probably overkill (it requires PS units and Fans kit)
    HPE FlexFabric 5944 48XGT 6QSFP28 Switch (JL836A) <- probably overkill (it requires PS units and Fans kit)

    In any case you have to consider that having front-plane ports running at 10Gbps (SFP+ or XGT, it doesn't matter) requires having some ports (erroneously referenced as "uplink" ports) running at ever higher speeds (40Gbps or 100Gbps)...so it's quite normal to see 24/48x10Gbps + 4/6x40/100Gbps...that's to say that you need to pay attention how then you (re)connect your ToR switch to your Core.

    Edit: I forgot to mention the HPE OfficeConnect 1950 Switch series (it's positioned as low/mid end compared to the above listed switch series), within that series the HPE OfficeConnect 1950 12XGT 4SFP+ Switch (JH295A) model provides exactly twelve 1/10GBASE-T ports and additional four SFP+ ports to be used as uplinks. If 12 ports are not enough you could always plan to purchase two and create an IRF cluster and distribute servers' links to both switches halving their usage. I'm not sure this recommendation fits your needs but it is just a possible path.
