P3x00 with Storage Spaces Direct

Hi,

we got a 4 node cluster running Storage Spaces direct, using P3700 NVMes as caching devices. There seems to be a problem with this combination:

This can lead up to BSOD, which you can imagine is horrible in a production Cluster.

I could not find any information from Intel on this topic. Can anyone help me out with this? I don't know if this is a Microsoft problem, or if a new driver/firmware could help out.

I have also posted this in Microsoft TechNet.

Any help is highly apreciated!

Best regards,

Andreas
