IBM Cross System Coupling Facility (XCF)

From Wikipedia, the free encyclopedia

XCF establishes network communication in a sysplex. This allows applications in a sysplex to transmit (send and receive) data across systems. With XCF, applications can distribute specific functions between multiple processors and/or systems. As a result, an installation can spread the processing workload across the sysplex,talking advantage of individual system features, as well as providing capabilities for the applications.
