We maintain the 2 x 1 GbE network adapters for vMotion and then configure multiple VMkernel interfaces using the same NIC and network. Each time you add a VMkernel adapter and enable it for vMotion, you create a new stream. With more streams, there is greater bandwidth utilization.

Even though 2 x network adapters are dedicated to vMotion, only 1 of the uplinks will be used during a vMotion activity if only one vMotion vmkernel is configured. Adding an additional vmkernel will allow both to be used.

Per the VMware KB above "After making these configuration changes, when you initiate a vMotion, multiple NIC ports are used. Even when performing a vMotion on just one virtual machine, both links are used."

Also the question states "Per the defined logical network configuration, there are two network adapters each" which suggests that changing this to combine vMotion/Mgmt traffic may not be possible based on the customers requirements (as the logical network architecture is already defined by them)
