A flexible architecture for embedded firmware of a multiple protocol switch can be implemented on a variety of hardware platforms. Hardware components of a SAN switch are embodied as cooperative modules (e.g., switch modules, port modules, service modules, etc.) with one or more processors in each module. Likewise, firmware components of a SAN switch can be assigned at initialization and/or run time across a variety of processors in any of these modules. The processors and firmware components can communicate via a messaging mechanism that is substantially independent of the underlying communication medium or the module in which a given processor resides. In the manner, firmware components can be reassigned (e.g., in a failover condition), added or removed without substantial disruption to the operation of the SAN.
