A system for implementing a failover policy includes a cluster infrastructure for managing a plurality of nodes, a high availability infrastructure for providing group and cluster membership services, and a high availability script execution component operative to receive a failover script and at least one failover attribute and operative to produce a failover domain. In addition, a method for determining a target node for a failover comprises executing a failover script that produces a failover domain, the failover domain having an ordered list of nodes, receiving a failover attribute and based on the failover attribute and failover domain, selecting a node upon which to locate a resource.

Flexible failover policies in high availability computing systems

A high availability computing system includes a plurality of computer nodes (for example, a server system) connected by a first and a second network, wherein the computer nodes communicate with each other to detect server failure and transfer applications to other computer nodes on detecting server failure. The system incorporates methods of maintaining high availability in a server cluster having a plurality of nodes. A group communications service, a membership service and a system resource manager are instantiated on each node and the group communications service, the membership service and the system resource manager on each node communicate with other nodes to detect node failures and to transfer applications to other nodes on detecting node failure.

Maintaining process group membership for node clusters in high availability computing systems

The invention provides a system and a method for splicing network connections. In one embodiment, the method maintains first and second connections with first and second network nodes respectively; and selectively splices the first and second nodes based on application header information associated with inbound data packets received from the first node in reply to a request from the second node.

Sub-application layer data transfer in a network comprising a layered architecture

A network caching device includes primary storage and secondary storage. The network caching device creates a set of metafile entries, each of which contains metadata for a logical grouping of related objects cached by the network caching device, and uses the set of metafile entries to reduce accesses to the secondary storage in response to requests for the objects.
