I would recommend to use a dedicated nic for vMotion traffic. Disable vMotion on management network.

You should not configure vMotion like that... If you want multiple vMotion networks follow this guide -

If you have 4 physical nics and if you want to use all 4 nics for vMotion, the same KB linked by joshopperjoshopper applies.

It is just that you have to create 4 different vmkernel ports with different IPs and have only 1 physical nic associated with it.

AS per the best practice, following rules should be follow.


Keep separate ESXi or ESX management traffic from other traffic (vMotion, FT, virtual machine) Avoid SPOF (Single Point Of Failure) – redundant physical switches


vMotion traffic should go through not routed (separate IP subnet) network, due to security reasons (vMotion traffic is not encrypted).


vMotion traffic needs 1Gbps connection.


Storage (NFS, iSCSI) traffic should be isolated from other type of traffic on physical level (separate pNIC and vLAN_ID).

Storage traffic need at least 1Gbps connection to give enough throughput and low latency to storage


kindly go through below link for setup best infrastructure with 4 NIC

you can use 2 nics in 1st vSwitch, have separate vLANs for management and vMotion. get both nics trunked with the vLANs.

Use the next 2 nics in 2nd vSwitch for Production vm networks.

This will give you redundancy.
