Cisco UCS nfnic queue depth.

[rebelinux]

Is there any documentation procedure for setting nfnic queue depth on esxi?

I can see there is a procedure to change it using fnic driver but not sure if it can be done using nfnic that ships with esxi 6.7u1 nativelly.

Any help really appreciate.

Best,

Happy New Year!!!!

I know this was a post from a while back, but figured I'd reply for you.

Looks like there is a known issue with the nfnic driver that you can't adjust the queue depth and it's default is now 32.

Should be fixed in the nfnic driver 4.0.0.28.  That said, I only see 4.0.0.24 as the most recent release.  So we are still waiting on Cisco for the the fixed version.

Good news here, Cisco released an updated nfnic driver last week, 4.0.0.35 as part of the UCS Blade Software 4.0.4 package.  You can find it in the VMware Driver ISO here: https://software.cisco.com/download/home/283853163/type/283853158/release/4.0(4)
