I350-T2 OEM RSS not working Window 2012 R2.

[ncote]

Hello

I have been doing different benchmarks using iperf-2.0.5.2-Win32 and NTttcp.exe verion 5.28. I noticed that only one CPU core is handling the network activity as indicated the Perfmon \Per Processor Network Activity cycles\0, Intel(R) I350 Gigabit Network Connection to 23. In my case its always core 6 that is in use. the 22 other cpu always show 0 activity. This is also visiable by watching the TaskManager Performance tab CPU per core activity during the test. only Core 6 has close to 100% activity.

The network card is an intel I350-T2 OEM card using ProSet drivers version 19.1.51.0 on a Windows 2012 R2 server. The hardware is Dell T7500 Workstation with 2 Xeon X5660 CPU and 96 GB of ram.

I have RSS enabled in the Intel. driver settings.

Powershell shows the RSS settings for my primary nNIC.

Another interesting issue is that SMB3 does not detect the I350-T2 NIC as having RSS enabled.

The active Intel I350 intel nic is Interface index 27.

Hi Naim,

It is funny you should post this because I ordered an I350-T2 for a Windows Server 2012 R2 system which arrived this morning, fitted it and am now experiencing exactly the same issues as you.

No combination of drivers works, and no auto-detection of the interface. Quite frankly this is atrocious, I bought an Intel NIC as I wanted a best-in-class NIC and I didn't expect problems at the first hurdle (probably like yourself).

The PCI-E slot is definitely fine as I tried a different NIC in it and that works fine. The operational LEDs flash so I'm assuming the card isn't faulty.

I will e-mail / call man+dog at Intel until someone hopefully helps, and if I get a solution I'll post it here!

Hi Dave

I did some more investigating and found that the card I have is an i350-AM2 ( purchased on ebay here : http://www.ebay.ca/itm/151247646136?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 Intel I350AM2 Dual Port Gigabit 1000M PCI E Network Server Adapter I350 AM2 | eBay

I found a thread here discussing the difference between the i350-T2 and the i350-AM2, basicaly arguing that the i350-AM2 and 4 variants are not good performers.

Although the i350-AM2 uses a different chipset, the offical intel spec sheet still shows that the chipset is suppose to support all modern features such as RSS which is found on all modern NIC's. http://www.intel.com/content/www/us/en/ethernet-controllers/ethernet-controller-i350-family-brief.html Intel® Ethernet Controller I350 Family: Brief

So David is your card the real i350-T2 from intel or an i350-AM2 OEM version such as mine ?

Please keep me posted on any progress you make.

Naim.
