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,
- ESXi power management should be disabled
- UCS Firmware must be at a minimum version of 2.2(2c)
- 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.
