SilkWorm 12000 Reference Topologies

The following architectures are tested and recommended by Brocade. These architectures take into
account current support levels, and are recommended for use in a redundant dual fabric environment.
Other topologies are tested and supported as well. If one of the reference topologies does not fit
requirements, please consult the service provider or a Brocade Systems Engineer to create a customized
and supported topology. For the topologies in this section, the fabric port count is shown as a range. This
range is based on the number of ISLs connecting the switches. The higher the fabric port count, the lower
the ISL count and performance. Conversely, the lower the fabric port count, the higher the ISL count and
performance.

Single chassis topology

This topology is a simple, single chassis fabric comprised of two logical SilkWorm 12000 switches.
