CISCO UCS VIC 1240 and VIV 1340

Is it VIC 1240 or VIC 1340?  We haven’t tested VIC 1340 yet.  Ray (Ray Budavari <rbudavari@vmware.com>) has tested VIC 1240 and recommends the following tuning for performance:

NetQueue	UCS Ethernet Adapter Policy & VMQ Connection Policy	8	Provides additional queues for traffic using different DST Acs (benefits when there is a mix of both VXLAN and VLAN traffic)
NIC interrupt timers & TCP LRO	UCS Ethernet Adapter Policy	64us & Disabled	Reduce NIC adapter interrupt timers to enable faster processing of receive traffic
Multiple VTEPs using Load Balance - SRC ID policy	NSX VXLAN Configuration	2 VTEPs	Multiple VTEPs enables balanccing of network traffic processing across two CPU contexts
Network IO Control	VDS	Enabled	Provide additional TX contexts / CPU resources foor transmit traffic

Also,

1. ESXi power management should be disabled
2. UCS Firmware must be at a minimum version of 2.2(2c)
3. ESXi hosts require ENIC driver 2.1.2.50 or newer

Above tuning is critical to improve performance.

Like all components within NSX, dvFilter’s performance is also influenced by the hardware offloads etc.,.  Check out the NSX Performance slides from Vmworld that I sent earlier.  Feel free to setup up a quick sync up call to discuss, if still in doubt.
