Abstract
Techniques are disclosed for provided automatic fault tolerance in data storage systems and other computer systems managing access to shared computing resources using the construct of a resource instance manager together with an architecture for designing and implementing task-oriented state-based commands for accessing the shared computing resources. A set of resource instance managers respond to all commands requesting access to a set of respective shared resources. Access to each shared resource is managed by a unique resource instance manager for that resource which maintains a consistent state for that shared resource. When commands are designed appropriately, the system can be restored using a system state history maintained transparently by a system-provided application program interface.
