Abstract
An apparatus, program product and method utilize cluster data port services within a cluster infrastructure to provide reliable and efficient communications between nodes in a clustered computer system. The cluster data port services present an abstracted transport service that encapsulates and manages the establishment of multiple connection paths between a source node, a target node and one or more backup nodes in such a manner that a cluster data port is effectively utilized as single data port from the perspective of a user program.
