What Is MVS (Multiple Virtual Storage)?
SearchDataCenter, Thursday, October 10th, 2024
MVS (Multiple Virtual Storage) is an OS from IBM that continues to run on many of IBM's mainframe and large servers. MVS is said to be the OS that keeps the world going. The same could be said of its successor systems, OS/390 and z/OS.
The payroll, accounts receivable, transaction processing, database management and other programs critical to the world's largest businesses are usually run on an MVS or successor system. Although MVS has often been seen as a monolithic, centrally-controlled information system, IBM has repositioned it (and successor systems) as a "large server" in a network-oriented distributed environment, using a 3-tier application model.
