Security for NVMe over Fabrics is highly sought by customers and evolving at a fast pace. Experience with initial implementations uncovered a few shortcomings in the original design of certain NVMe/TCP security features that have resulted in recent security protocol changes. Furthermore, a lack of understanding on how configured single-system NVMe over Fabrics security policies interact led to the standardization in NVM Express of an interoperability framework. This session will explain these recent developments in NVMe-oF security and their importance to achieve a secure SAN.
