In computing, a '''Parallel [[Sysplex]]''' is a [[computer cluster|cluster]] of [[IBM mainframe]]s acting together in a single system image, usually with [[z/OS]]. A Parallel Sysplex combines data sharing (typically using [[Peer to Peer Remote Copy]]) and [[parallel computing]] to allow a cluster of up to 32 computers to share a workload for [[high performance computing|high performance]] and [[high availability]]. Parallel Sysplex provides [[horizontal scaling]].

The forerunner to Parallel Sysplex was '''Virtual Coupling''', a technique which allowed up to 12 [[IBM 3090]] systems to execute jobs in parallel. The true Parallel Sysplex was introduced with then-new mainframe models in April, [[1994]]. IBM continues to improve and enhance Parallel Sysplex.

Major components of a Parallel Sysplex include:
