At the expense of some additional data transfer, system and user performance may be improved by the extended swap data handling shown in Fig. 1. It shows the MVS (multiple virtual storage) page swapping operations between main storage and auxiliary storage (e.g., DASD (direct-access storage device)) organized into five types of pages in a user's address space in a swap data set 14 and a page data set 15, called an "extended swap", since it diverts all (or almost all) of the paging traffic caused by swaps into swap datasets.
