The other day I was tasked with doing QoS on UCS for NFS/VMware. This first thing I did was read Brad Hedlund's article in QoS on Cisco UCS. This provided some great direction as Brad's articles usually do.
1. The first thing I did was to enable and adjust all the native UCS QoS system classes: Note the MTU for NFS and the weight.
2. Next I create QoS policies for all VMware/System networking needs:
3. Finally I created my vNIC templates and then applied the created QoS polices to each respective vNIC.
4. Upstream I ensured that Jumbo Frames were enabled and that all QoS polices were being honored. After some testing, it worked like a charm.
