  • vSphere networking query

    Hi,

    In an environment with 4 ESXi hosts, each with 8 physical NICs, what would be a optimal configuration for the network? I am looking for just an overview on how many NICs for VM traffic, how many for vMotion and how many for the management network. Any for failover etc?

    Thanks.

    Our setup is this

    2 ESXi 4.1 hosts with 12 NICS.

    2 NICS for management
    2 NICS for production
    4 NICS for vMotion
    4 NICS for iSCSI

    Probably a bif of overkil for them but it works like a dream for us.

      We use Dell M600 / M610 blades and have only 4 nics. We use:

      2 NICS for Management and vMotion (Seperate VLANS)
      2 NICS for VM traffic (Seperate VLANS)

      We use F/C for storage and this works fine for us.

        My recommendation is to always have redundant physical NIC's for Service Console and vMotion. If you can have one NIC on different physical cards (i.e. NIC1 = Onboard & NIC2 = Addon Card). You can also setup the SC and vMotion to use other other NIC as the failover.

        Then you can use 2-4 cards for Virtual Machine traffic but it all depends on your network throughput. You could setup an additional NIC as a failover, etc.

        There is no need to use all 8 NIC's; unless you have a specific need.

          You do realise that ESXi doesn't have a service console.
