In [[IBM]] [[zSeries]] [[mainframe computer]]s, a '''Parallel Sysplex''' is a [[computer cluster|cluster]] of zSeries mainframes acting together as one single [[Sysplex]]. It 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]].

The forerunner of the Parallel Sysplex was the '''Virtual Coupling''', a technique which allowed up to 12 [[3090]] systems to execute jobs in parallel. The true Parallel Sysplex was introduced with the [[zSeries 900]] in April of [[1994]].

Major components of a Parallel Sysplex include:

* [[Coupling Facility]] (CF) hardware, allowing multiple processors to share, cache, update, and balance data access

* A [[Sysplex Timer]] to synchronize the clocks of all member systems
