Abstract
The present invention provides a system of computers where one is active and processing data while the others standby. Data generated by the system is stored on at least two external, shared storage devices. The states of the computers are managed by a software system manager. This provides for a quick transition of a standby computer to an active computer when the system manager detects a need for a state change.
