Processor Storage Management in the 21st Century, or Paging Still Matters

摘要

Managing the balance between real and auxiliary storage has been a source of many performance problems and a matter of concern since the earliest days of MVS. Adding expanded storage to the mix may have created more problems. Storage eventually became very inexpensive so nobody needed to have a paging problem--right? Wrong. We'll look back to origins and solutions, we'll look ahead to potentially staggering paging problems of the future, and we'll explore ways to avoid them.
