E810-XXV-2 RSS Number of receives queues stucked to 1

[GiovaBx]

Hi all,

I'm testing an E810-XVV-2 dual port network card and I'm facing really bad performance compared to an old (and unfortunately obsolete) X520.

At the moment I need just 10Gbps links.

Under Windows 10 64 bit 22h2 (desktop)  I want to use the two ports of the board to read from 12 gigabit cameras connected to an Aruba 2730F switch. Each port of the board read 6 cameras (about 5Gbps). Note: these cameras sends frames using 8K UDP telegrams (i.e. a lot of small telegrams). 

I usually does not tweak too much the driver settings: I just enable the jumbo frames, disable all the CRC offloading options and increase the number of receive buffers. All the other options, in particular the RSS and the number of receive queues, are kept to their default value.

Unfortunately this board seem to ignore what it is set as "number of receive queues" and always use 1. As you can see the default is 16

but when I check in the powershell the actual number is 1.

When I start the software to grab from the camera is see that all the load is handle by a single CPU thread.

I have the same behaviour in two different PCs with different motherboards and processors: a single i7 processor MB and a dual Xeon processors MB.

Any hint to get this setting to a value different from 1: simple a single CPU thread is not able to handle all the interrupts for the incoming telegrams.

Hi GiovaBx,

Good day!

Could you please proceed with 16 Queues and Dual CPU thread.

Kindly find the below datasheet link and required details will be available in Page no: 33 > 1.4.2 > Host Memory Objects.

Hi Poojitha,

Sorry but I can't understand what you ask me to do.

Can you give me more details?

I read page 33 of the datasheet but I have no clue on what I should tweak to make it works as desired.

Maybe I did not explain me correctly.

I try to change the number of queue both using driver settings and using power shell command, but the value remains always to 1 no matter the value that I set

Hi GiovaBx,

The adapter E810-XVV-2 that you are using is compatible only with servers and not with the desktop.

We request you to check with the desktop-compatible adapter and please let us know the status.

Thank you!

Do you mean that if I want to use this adapter I must install windows server?

Does this mean that Intel does not really make anymore any 10/25/40 Gbps adapter compatible with Windows Desktop?

This explain me why I can't find any Intel nic that works as I expected (and how the old X520 does).

Really a bad news.

Hi GiovaBx,

We apologize for any inconvenience caused. We request that you allow some time to check if there is an option to change the queue value, and we will get back to you with an update shortly.

Hi.

Any news?

Can you suggest any Intel solution that works as it should (or as the X520 used to do) on Windows 10 Desktop?

Hi. I read the guide that you suggest me.

My problem is still there, but I think I found a possible problem.

I set the each port of the network card to use 4 not overlapped threads (real core) on the first CPU (I have a dual CPU system and the network card is handled by the first one)

As you can see in the following screenshot, the first port is stucked to use 1 RSS queue, while the second can use 4 (and actually uses 4 as shown in the indirection table)

Unfortunately, this command (that I found in the documentation) does not work

Set-NetAdapterRss -name E810_1.1 NumberOfReceiveQueues 4
Set-NetAdapterRss : A positional parameter cannot be found that accepts argument 'NumberOfReceiveQueues'.
At line:1 char:1
+ Set-NetAdapterRss -name E810_1.1 NumberOfReceiveQueues 4
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Set-NetAdapterRss], ParameterBindingException
+ FullyQualifiedErrorId : PositionalParameterNotFound,Set-NetAdapterRss

I will try to update drivers and firmware to see if after the update the problem is solved

[GiovaBx]

I just updated the driver to the Release 29.1 (i had the 28.3).

Now I get the right values (and behaviour) for the RSS queues

Now that I can configure the board as the older one, I can keep testing its performance
