When we were initially setting up vSphere networking, we set up multiple portgroups for vMotion (1 port group per NIC), and then one vmk per portgroup. At the time, our expert explained to me that we needed to do that to utilize the full bandwidth of our 2x10GB NICs. 

Fast forward a couple of years, said expert no longer works here, we now have 4x25GB NICs per ESXi, and I come across this: https://core.vmware.com/blog/faster-vmotion-makes-balancing-workloads-invisible

Reading this makes it sound like that doing this multiple portgroup/vmk vMotion setup is no longer necessary, and I can just use a single vMotion vmk/portgroup. Am I interpreting that correctly?

Thank you,
