As I prepared for EMC World earlier this year, I struggled when trying to determine the best way to communicate the changes that have occurred in the storage protocol ecosystem over the past 18 months. Since I also felt it was important to also explain how the storage protocols related to one another, I decided to try and create a single illustration that captured as much detail as possible. The "Storage Protocols" graphic is the result of this effort.

While I believe the result is accurate for the protocols shown, I know it's not 100% complete. For example, Fibre Channel is missing as a transport for NVMe over fabrics. Please don't read too much into this, I didn't include it because it would have made the diagram much harder to understand.

Questions, comments and corrections are welcome!
