Storage Spaces Direct Windows Server 2016 (1607) BSOD - Mellanox ConnectX-3 Pro (Dell)

Good afternoon,

There is very little documentation specific to Windows Server 2016, much of the RDMA/RoCE documentation referrers to Windows Server 2012(r2) Storage Spaces. So I figured I’d start a conversation in here to help others also looking at Microsoft Storage Spaces Direct (S2D) in Windows Server 2016.

I currently have an open case with Dell ProSupport regarding a BSOD my 2 Node cluster encounters. Either node will just halt and restart after 60 seconds when stress testing the environment. Each server is configured as follows…

  • Dell 13th Gen R730XD
  • 2x 120GB Intel SSDs SSDSC2BB120G6R (OS Mirror)
  • 6x 1.6TB SSDs SSDSC2BX016T4R
  • 6x 8TB HDDs ST8000NM0055-1RM112
  • 2x Intel DC P3700 800GB (Journal / Cache)
  • 256GB 2400Mhz Memory
  • HBA330 Mini Controller
  • 1x Mellanox ConnectX-3 Pro (MT04103) Dual Port SFP+ 10GbE (Firmware Version: 2.26.50.80 / Driver Version: 2.25.12665.0)
  • Running Windows Server 2016 DataCenter 1607 Build 14393.693

Each server has two links to a Dell N4032F Switch.

To rule out a possible fault with my switch config, Dell advised I directly connect the two nodes together. RDMA is engaged because I can see the traffic using performance monitor.

Here’s the order in which I’ve setup my environment…

  1. Install the OS and fully update/patch
  2. Set Windows Power Mode to Performance
  3. Install Windows Features - Hyper-V / File-Services / Failover-Clustering / Data-Center-Bridging
  4. Install Dell drivers for all hardware including the Mellanox nics. (I’ve tried both the Mellanox drivers and Dell’s. They appear to be the same. MLNX_VPI_WinOF-5_25_All_Win2016_x64 / Driver Version: 2.25.12665.0)
  5. I perform the network configuration. Essentially create a Hyper-V SET Switch joined to both ports of the Mellanox nic. I then create two vNics connected to the new Switch with a VLAN tag. (See attached file)
  6. I then create the Failover-Cluster and enable Storage Spaces Direct (See attached file)

Everything appears to be okay then it’ll randomly crash. Below is a memory dump. This is what I receive on either host. I want to upgrade the firmware but it’s a Dell product code so I’m stuck. It’s been three weeks and we still don’t have a working environment. I also have another debug output further below…

Can somebody at Mellanox please help? I’m tempted to buy two off the shelf Mellanox cards just to rule Dell’s firmware out of the equation.

Hi Thorir,

I managed to fix the issue. I had a support case open with Dell ProSupport for about 3 weeks. They too had issues trying to replicate the fault. I suggested the firmware was out of sync with the drivers they’d released. Anyway, they said try BIOS settings. I then spent the next 3 weeks reinstalling windows over and over because it would corrupt the install of Windows on occasion because of the BSOD’s.

In the end I was able to resolve the issue. There’s a BIOS setting IO Non Posted Prefetching. This was enabled by default on delivery of the servers. I disabled this setting and was able to run VMFleet for a few days hammering the system with no crashes. I fed this info back to Dell who then closed the case. They did acknowledge the firmware is a problem but said they can’t do anything about it other than raise a case for it to be updated. We just have to wait.

I think I’d buy Mellanox cards directly from Mellanox in future. I can’t see a way of upgrading the firmware as the firmware tools don’t recognise the cards at all. There’s no way to discover them because Dell have changed the identifiers the MFT’s look for. Mellanox was very unhelpful as I tried to raise a case with them, only to be told I don’t have support. Pretty annoyed at the time. Dell won’t give me a time or date for firmware or even if it’s on the cards. Mellanox did not want to know unless I paid more. Anyway, I hope this helps others.

May I add. The servers have been running fine for about a month and now we’re experiencing similar crashes again (not as often). This time Microsoft have a case open as I believe the mellanox side of things are sorted. Who knows, Microsoft might turn around and say there’s a firmware + driver mismatch on the Mellanox cards. It’s been a nightmare.

Anyway, I hope that BIOS setting helps others.

Sorry I forgot to mention…

You said you sorted it. How did you resolve it? Was it a BIOS setting or did you manage to make your own firmware? If that’s the case, maybe my more recent crashes are still related…

Many thanks

Hi,

I have been in having this same issue and have resolved it with help of Mellanox and pounding Dell ProSupport.

The problem is that accourding to Mellanox the supporting config for Mellanox ConnectX-3 is driver version 5.25 and firmware 2.36.5150 or higher, Dell has the driver but their firmware version is 2.36.5080 which is nearly year old.

Mellanox wants you to talk to Dell support (which is right) to fix this. If you have a Dell ProSupport then contact them but if not go to this website, http://www.mellanox.com/page/custom_firmware_table http://www.mellanox.com/page/custom_firmware_table (Dell card = MCX312A-XCB - MT_1080120023), and follow the instruction to create your own firmware image.

Kind Regards,

Thorir
