Abstract
Self-contained disaster detection for replicated multi-controller systems is described herein. A system as described herein can include a memory that stores computer executable components and a processor that executes computer executable components stored in the memory. The computer executable components can include a data synchronization component that replicates data written at a primary production site, resulting in replicated data from the primary production site; a status monitoring component that reads status identifiers contained in the replicated data at periods of a time interval, wherein the status identifiers are written by respective controllers at the primary production site; and a disaster recovery component that initializes a failover procedure at the primary production site in response to an absence of updates to a first threshold number of the status identifiers within a second threshold number of the periods.
