vSphere 6 VMkernel Traffic Types

vMotion traffic. Enables the VMkernel adapter to advertise itself to another host as the network connection where vMotion traffic is sent. The migration with vMotion to the selected host is not possible if the vMotion service is not enabled for any VMkernel adapter on the default TCP/IP stack, or there are no adapters using the vMotion TCP/IP stack.
Provisioning traffic. Handles the data transferred for virtual machine cold migration, cloning, and snapshot creation.
Fault Tolerance traffic. Enables Fault Tolerance logging on the host. You can use only one VMkernel adapter for FT traffic per host.
Management traffic. Enables the management traffic for the host and vCenter Server. Typically, hosts have such a VMkernel adapter created when the ESXi software is installed. You can create another VMkernel adapter for management traffic on the host to provide redundancy.
vSphere Replication traffic. Handles the outgoing replication data that is sent from the source ESXi host to the vSphere Replication server.
vSphere Replication NFC traffic. Handles the incoming replication data on the target replication site.
Virtual SAN. Enables the Virtual SAN traffic on the host. Every host that is part of a Virtual SAN cluster must have such a VMkernel adapter.
