What is the maximum number of threads that can be created per vNIC?
Answer D:
Reference： https://configmax.vmware.com/guest?vmwareproduct=vSphere&release=vSphere%206.7&categories=1-0
Correct Answer is C – 8.
The question is how many Threads per vNic, and it’s 8 not 10.
VMXNET 3 optimization
Using copy TX for small messages size (<=256B)
Optimized usage of pinned memory
Physical NIC improvements
Native driver support for Intel cards (removes overhead of translating from VMkernel to VMKLinux data structures)
CPU Scheduling Improvements
Up to 8 separate threads can be created per vNIC
To enable on VM level add:
ethernetX.ctxPerDev = “3” to vmx file
I knew it wasn’t D, just couldn’t find the documentation/white paper giving me the other number. Can you post a link to the 8 threads verbiage? Thanks
