Learning NVMe: A Program of Study

This is a “Program of Study” for NVM Express (NVMe) for those people who want to learn about the technology, but don’t know how to answer the question, “Where do I start?”

There is also a bibliography of material by subject matter for NVMe for those people who are looking to get to a specific subject. There are more subjects there for those people who are really serious about learning about NVMe and NVMe over Fabrics.

However, if you can make it through this “course,” you will have more-than-sufficient understanding of how NVMe and NVMe over Fabrics works. Some of these materials are a little older, but they are still good starting places for understanding general concepts.

I will continue to update this list whenever new material becomes available (and, of course, remove out-of-date material as well).

The 2.0 version of the NVMe Specification was ‘refactored,’ meaning that it was re-written from the ground-up to be easier for developers to understand and, well, develop to. Instead of having a “Base”, “Fabrics,” and Management” specification (which had a lot of overlap and became difficult to keep consistent), the new texts made things more approachable by combining elements into like categories.
