Why do we always see Responder CQE Errors with RoCE RDMA?

Anyone who has configured and used SMB Direct with RoCE RDMA Mellanox cards appreciates the excellent diagnostic counters Mellanox provides for use with Windows Performance Monitor. They are instrumental when it comes to finding issues and verifying everything is working correctly.

Many have complained about the complexity of DCB configuration but in all earnest, any large network under congestion which needs specialized configurations has challenges due to scale. This is no different for DCB. You need the will to tackle the job at hand and do it right. Doing anything at scale reliable and consistent means automating it.  Lossless Ethernet, mandatory or not, requires DCB to shine. There is little other choice today until networking technology & newer hardware solutions take an evolutionary step forward. I hope to address this in a future article. But, this I not what we are going to discuss here. We’ve moved beyond that challenge. We’ll talk about one of the issues that confuse a lot of people.

Why you should learn about SMB Direct, RDMA & lossless Ethernet for both networking & storage solutions

Server, Hypervisor, Storage

Too many people still perceive Windows Sever as “just” an operating system (OS). It’s so much more. It’s an OS, a hypervisor, a storage platform with a highly capable networking stack. Both virtualization and cloud computing are driving convergence of all the above these roles forward fast, with intent and purpose. We’ll position the technologies & designs that convergence requires and look at the implications of these for a better overall understanding of this trend.
