Fabric OS is not a true operating system, but more a series of software modules that interact with the Brocade Silkworm FibreChannel Switches and Directors.

The first generation of Fabric OS was developed on top of a VxWorks kernel and was mainly used in the Brocade 2000 and first 3000 series. Even today, a lot of production environments are still running the older generation Silkworm models.

The second generation of Fabric OS was developed on a PPC platform, and uses MontaVistaLinux, a Linux derivative with real-time performance enhancements. With the advent of the MontaVista solution, Silkworm Switches and Directors have the capability of hot firmware activation (without downtime for FC fabric), as well as a plethora of useful diagnostic commands.

Additional licensed products for Fabric OS include:

  • Secure Fabric OS (SFOS)
  • Brocade advanced zoning
  • ISL trunking
  • Advanced Performance Monitoring (APM)
  • Fabric Watch

Brocade Silkworm product family: 3016, 3250, 3850, 3900, 4100, 12000 and 24000.

Fabric OS is used by Hewlett Packard in their B-series switches.[1]
