Control and Management

The supervisor modules provide the following control and management features:

•A redundant central arbiter that provides traffic control and access fairness.

•A nondisruptive restart of a single failing process on the same supervisor.

A kernel service running on the supervisor module keeps track of the high availability policy of each process and issues a restart when a process fails. The type of restart issued is based on the process’s capability:

–Warm or stateful (state is preserved)

–Cold or stateless (state is not preserved)
