In IBM mainframecomputers, a Coupling Facility or CF is a piece of computer hardwarewhich allows multiple processors to access the same data. A ParallelSysplex relies on one or more Coupling Facilities. A coupling facilityis a mainframe processor, with memory and special channels, and aspecialised operating system called Coupling Facility Control Code. Ithas no I/O devices, other than the CF links. The information in the CFresides entirely in memory as CFCC is not a virtual memory operatingsystem. A CF typically has a large memory - of the order of severalgigabytes. In principle any IBM mainframe can serve as a couplingfacility. The CF runs no application software. When originallyintroduced, the CFCC executed in a separate mainframe unit that wasessentially a processor without I/O facilities other than the CF links.Later IBM enabled the use of an Internal Coupling Facility where theCFCC runs in an logical partition defined in standard processor complexand communicates over internal links within that processor complexhardware. Links to another processor unit are over copper cables. Seller Inventory # 9786135995978
