Abstract

A method and apparatus for maintaining the integrity of configuration data in redundant, fault tolerant network appliances. The apparatus comprises a pair of network appliances coupled to a network. The appliances interact with one another to detect a failure in one appliance and instantly transition operations from the failed appliance to a functional appliance. Each appliance monitors the status of another appliance using multiple, redundant communication channels. The configuration data of the network appliances is distributed and stored in a redundant manner in storage system that is accessible to the network appliances. The configuration data is updated on a regular basis while the network appliances are operational. Upon recovery of previously failed network appliances, the appliances access the stored configuration data such that the appliance may boot-up to operate in a manner as if a failure never occurred.
