Configure your network for best performance

Contributors netapp-forry NetAppZacharyWambold

Ethernet networks vary greatly in performance. You can maximize the performance of the network by selecting specific configuration values.

  1. Connect the host and storage ports to the same network.

    It is best to connect to the same switches.

  2. Select the highest speed ports available.

    10 GbE or faster ports are best. 1 GbE ports are the minimum.

  3. Enable jumbo frames if desired and supported by your network.

    Jumbo frames should have an MTU of 9000 for ESXi hosts and storage systems, and 9216 for most switches. All network devices in the data path — including ESXi NICs, storage NICs, and switches — must support jumbo frames and should be configured for their maximum MTU values.

    For more information, see Check the network settings on the data switches and the switch vendor documentation.
