1:N process redundancy
The system backs up each active process running on one node to all the other nodes. When an active process fails, one of its standby processes promptly takes over without impacting any other service.
1:N process redundancy provides the following benefits:
Improves service availability.
Enables the system to quickly regain reliability after device status changes in such conditions as insertion and removal of cards, IRF split, and removal of an IRF member.
