Sometimes you need to convert a Brocade model name to an IBM model name (or the other way around). One way to assure yourself with scientific accuracy which type of switch you are working on, is to telnet or SSH to a switch and issue a **switchshow**command. You will get a *switchType* value. In this example, my switch is a switchtype 27.2.

IBM_2005_H08a:admin> switchshow switchName: Switch01 switchType: 27.2

Or if you are using the Web GUI, you can also see the switch type on the opening screen. In this example the switch is a type 34.0.

Having scientifically determined the type of switch, we can now use my decoder ring to determine the IBM machine type, IBM model name and the Brocade model name. I have ordered the switches by Type number. There are three things to note:

- Brocade have dropped the Silkworm branding, so I have dropped it too.
- Each switch type has sub-types, for example 34.0 and 34.1. The difference is a sub-version number which is normally not published or documented.
- IBM announced 16 Gbps SAN switches on August 16, 2011 so I updated the chart on that date.

If you use Data Center Fabric Manager (DCFM), it actually displays the Switch Type using Brocade model names. Here is an example report from the DCFM we are running in my lab. This level of information is very helpful.
