Our Speedmap

The network technology named “10GbE” means throughput is 10Gb/s, and if you’re like most people, you would naturally believe the network called “32GFC,” means throughput is 32Gb/s. The reality is the name matches the speed for Ethernet, but surprisingly not for Fibre Channel. The speed of the network is significantly less than the names for each generation of Fibre Channel.

This was not much of an issue is when the naming logic was “close-enough” at 1Gb FC and the difference between name and speed was .15Gbps. But at 32GFC, the gap is almost 5Gbps, and it’s snow-balling. I’ve called on the Fibre Channel industry to update their road map so the naming accurately reflects the speed of the network in Gb/s….just like we’re used to with Ethernet, and my request has fell on deaf ears. To hold us over, TheFibreChannel.com has created the Official Fibre Channel Road Map Translator.

As you can see below, we have taken the liberty of renaming each generation and re-introduced “Gb” in the name. By looking at the name, users can easily make an apple-to-apples comparison with Ethernet. I’ve also listed throughput in Gb/s, the well-established convention for network speeds. By using this road map, you will no longer need to convert from MB/s full-duplex to Gb/s half-duplex, in order to get the most widely used specification for network performance. Download PDF.

One of the most interesting data points is that 32GFC is actually 27Gb FC; more of a head-to-head competitor with 25Gb Ethernet than previously thought.
