Meaning of MULTIPLE VIRTUAL STORAGE

 
Computing Dictionary
 
 Definition: 

(MVS) Release 2 of os/vs2, called MVS because it had multiple 16 MB virtual address spaces, in contrast to svs. MVS ran on the ibm 390 series mainframes. It became MVS/SP, then MVS/XA (with 31-bit addressing) and then MVS/ESA.

MVS/Open Edition (MVS/OE), aimed at the growing open systems market, added tcp/ip and unix support in an MVS address space, allowing users to run IBM, cics-type applications, batch applications and Unix.

MVS/ESA was repackaged as os/390 as a marketing exercise but it's basically the same thing.

Version: 5.1.
