Multiple Virtual Storage (MVS) is the most commonly used operating system on the System/370, System/390 and IBM Z IBM mainframe computers. IBM developed MVS, along with OS/VS1 and SVS, as a successor to OS/360. It is unrelated to IBM's other mainframe operating system lines, e.g., VSE, VM, TPF.

==Overview== First released in 1974, MVS was extended by program products with new names multiple times, retaining the term MVS in the nomenclature: first to MVS/SE (MVS/System Extensions), next to MVS/SP (MVS/System Product) Version 1, next to MVS/XA (MVS/eXtended Architecture), next to MVS/ESA (MVS/Enterprise Systems Architecture),
