MVS: Evolution of MVS, MVS filesystem & Closely related operating systems

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.
