napp-IT all-in-one/vmxnet3s jumbo frames?

[kroem]

Is there a working solution to get jumbo frames working on napp-it inside a ESXI host?

I tried one solution, to change drivers to solaris 11 (the ones in the d/l is 10?), but then the SMB performance is horrible with drops etc (unusable).

I'm currently only getting about 3Gbps (nappit - debian) over a 10Gbe dvSwitch. Debian - debian is getting ~6Gbps.

No one?

Yeah, I did that but it screws up persistent connectivity

you may also try ESXi 5.5U2 (have not tried myself)

thanks, I'll try that!

It's very hard for esxi to pump full bandwidth to 10gbe since it is designed to move many vm's of traffic versus 1 vm. Pinning cores seems to help with RSS (multiple dispatch cores) to tx/rx but good luck getting 1 vm to pump full 10gbe using a VM!

I bet if you had direct-path you could do it though!

Hmm, yeah..I dont need full 10G, but want at least 5-6G. I mean ESXi can push it between my other VM guests so...

I'm getting some DAC cables soon, so will have 2x10G, might do passthrough instead.

Hey, that seemed to have worked, somewhat. I can set it to jumbo now, and getting 5+G.

Here is my last crack at enabling jumbo frames in my napp-it AIO almost a year ago and was running into the same erratic problems.

Does anyone care to do a semi-walkthrough on this if success is being achieved and is repeatable?
