Question regarding RSS Profile as default on Driver(I350)

SHWAN6 · ‎09-14-2017

Installed Windows 2012 R2 : RSS Profile : NUMAStatic (Default)

After Installed NIC Driver(I350 4 Port) : RSS Profile : Closest

I want to know why Intel sets RSS Profiles to Closest.

Closest was default value on Windows 2008/R2.

If you just don't change from Windows 2008/R2, it is fine. I can change.

But I need to know there is any reason.

Actually I need to change to NUMAStatic, but I have concern about to change RSS Profile, if there is any reason to set "Closest' as default.

Hi Kuwit,

Thank you for posting in Wired Communities. I will further check for you.

Thanks,

Hi Kuwit,

The reason RSS profile is set to "Closest" as default is to improve CPU utilization. If you wish to use NUMAstatic, this is also supported, you can refer to below website for reference:

Thanks for the answer.

I already read one of known issues which in you answer

I'm curious for that even there are known issues, does Intel sets closest to improve CPU utilization for Windows Server 2012/R2?

One more question about RSS Profile

Tested on below system

- HP DL360 Gen9 (2667 v4 * 2ea)

- 1GB 4port 366FLR (Intel/1G*2ea Team/LACP)

- Windows 2012 R2 Standard

- RSS : Enabled

- RSS Queue : 8

I expect 16 queues will working with "Closest"

But result is below.

Closest - around 8 queues work

ClosestStatic - 16 queues work

NUMA - around 12 queues work

NUMAStatic - 16 queues work

Is this result correct you designed?

HI Kuwit,

Thank you for the update. Yes, this is to reduce CPU utilization. For the results, can you share what are the commands with the parameter you executed?

Thanks,

Hello,

I can not see clear what do you ask for, I answer both which I understand.

To set RSS configuration,

NIC properties of "Device Manager" or Set-NetAdapterRss -Profile "OO" on powershell.

To make load

Hello,

The server was only for testing, I already reset whole things even OS.

It means I can not give you a log which you requested.

I asked about your RSS design of profiles.

By the way, let me know what do you want get more information.

idata · ‎10-11-2017

Hi Kuwit,

Thank you for the update. I will try to check based on the information and will update you if I need more information.

Hi Kuwit,

Further checking, since the "closest" is dynamic, it will change based on load, hardware configuration, environment, and other things running on the system and the network.

In order to come up with best performance, this should be done with the actual data and load expected while monitoring a number of factors such as CPU, RAM, and disk utilization among other things.

Thanks,

Sharon

Hello Sharon,

Thanks for the answer. It helps me.

I wonder if you have a document about to define RSS Profile(Including dynamic or not).

I couldn't find it.

idata · ‎10-15-2017

Hi Kuwit,

You are welcome. You may refer to our User guide for some reference information but it did not have specific information about including dynamic or not.

Here is the reference download link:
