A sysplex refers to a tightly-coupled cluster of independent instances of the z/OS operating system.

In 1990, IBM mainframe computers introduced the concept of a Systems Complex, commonly called a Sysplex, with MVS /ESA SPV4.1. This allows authorized components in up to eight logical partitions …

In 1990, IBM mainframe computers introduced the concept of a Systems Complex, commonly called a Sysplex, with MVS/ESA SPV4.1 in 1990. This allows authorized components in up to eight LPARs to …

Parallel Sysplex® is an IBM Z® feature that links up to 32 z/OS® systems into one logical, high-performance computing platform. It lets you run and manage multiple z/OS instances as a single …

IBM’s Parallel Sysplex systems are multiprocessor clusters that can support from two to thirty-two mainframe nodes (typically S/390 or zSeries systems).1 A Parallel Sysplex system is nearly linearly …

Figure 1 shows a sysplex of two z/OS systems, SYSA and SYSB, where both systems are connected to a Sysplex Timer and a coupling facility and can access the sysplex couple data set and the CFRM …

In 1990, IBM mainframe computers introduced the concept of a Systems Complex, commonly called a Sysplex, with MVS /ESA SPV4.1. This allows authorized components in up to eight logical partitions …

A Parallel Sysplex® is a sysplex that uses multisystem data-sharing technology. It allows direct, concurrent read/write access to shared data from all processing nodes (or servers) in the …

In September 1990, IBM introduced the SYStems comPLEX, or sysplex, to help solve the difficulties of managing multiple z/OS systems. This established the groundwork for simplified multisystem …

A Parallel Sysplex is a collection of z/OS systems that cooperatively use certain hardware and software components, to achieve a high-availability workload processing environment.
