Having only one TCP/IP stack places a limitation in being unable to create more than one default gateway, if you wish to have one for your Management network but also a separate one for your NFS traffic. You would be forced to use a single gateway and then populate the routing table with static routes. This is not a very scalable solution for those with robust or unique VMkernel networking requirements.
vSphere 6.0 allows the creation of multiple TCP/IP stacks. Each stack has its own routing table and its own DNS configuration.
esxcli --server=<vCenter hostname> --vihost=<ESXi hostname> --username=<vCenter administrative user> network ip netstack add --netstack=<Name of new TCP/IP stack>
Example:
esxcli --server=vcenter01.company.com --vihost=esxi05.company.com --username=root network ip netstack add --netstack=nfsStack
esxcli --server=vcenter01.company.com --vihost=esxi05.company.com --username=root network ip netstack list
