Storage Protocol Differences and FCoE Diagrams

Just thought I would share these diagrams that I used in a recent training session. I used them to explain the differences in the storage protocols that may be used for a vStorage Cloud and how FCoE works. Click on the images for a larger view.

Storage Protocol Differences

The first image shows the differences between the common storage protocols and what it takes for the data to get from point A to point B.

FCoE Packet

This diagram demonstrates the FCoE packet. The top block is an Ethernet Packet and the bottom block is the FCoE data.

Converged Network Adapter

This diagram shows the data flow within a Converged Network Adapter (CNA).

Converged Enhanced Ethernet Bridge

This diagram is the Converged Enhanced Ethernet Bridge. CEE in one end, FC out the other.
