Recently I was setting up a new 5.5 cluster with NIOC and I noticed all the new NIOC pre-build categories:
Some are obvious but others are a little more questionable. After a great discussion with VMware support I found out the following:
- NFS traffic – This is traffic using the NFS bindings in ESXi (not guest NFS traffic) only ESXi NFS traffic
- Management Traffic – ESXi management traffic only – connections between vcenter and ESXi
- vMotion Traffic – vMotion and heartbeats
- vSphere storage Area network traffic – I had a lot of questions on this one but it turned out to be simple vSAN only traffic
- vSphere replication traffic – Traffic coming from the vsphere replication appliance only no other replication traffic
- iSCSI traffic – As expected it’s traffic to ESXi that is iSCSI using hardware or software initiator
- Virtual Machine traffic – Traffic out of guest virtual machines
- Fault Tolerance Traffic – Traffic specific to vmware FT
There is all the predefined ones… what if I create a user defined category and assign it to my NFS port group… which assigns NIOC. Simple the one with the larger share.
