Architecture of a cluster management system

   An architecture that coordinates transitions in the system state of a set of cooperating computers. Such coordination is critical to achieve the quality of service goals such as availability, scaleability, and single system ease-of-use and administration. The advantage of this architecture is in it's ability to maintain very high levels of availability, scaling, and ease-of-use across a very diverse set of computers and be leveraged by a broad set of applications

     The invention defines a set of architectural concepts and a set of operations that can performed and implemented in terms of those concepts. The key concepts being the ability to define groups of related and cooperating servers, being able to dynamically determine how those groups are related to other groups, and being able to perform "transitions" that automatically notify related servers of the transition, and finally being assured that such a transition will occur atomically across a distributed system. The architecture defines the underlying components that support those concepts and enable them to be implemented easily across a broad set of computers and applications.

     The advantage of using clustered systems has been identified in numerous contexts, particularly by "cluster" managers that can be purchased from various hardware and software vendors. Typically the architecture of those products relies on a quorum mechanism and a fully distributed architectur...
