6.4 Expanded Storage Concepts

When the 3090 processor series was first introduced, IBM
referred to "extended storage" and "expanded storage"
interchangeably.  Since then, IBM has begun standardizing the
use of the expression "expanded storage," but the term
"extended storage" is still present in much of its
documentation.  In our constant goal of maintaining complete
compatibility with IBM developments, CA MICS data element
names and documentation sometimes refer to "extended
storage."

The following sections explain the expanded storage concepts.

    1 - Overview
    2 - Expanded Storage Control
    3 - Swapping and Migration to Auxiliary Storage
    4 - Effectiveness of Logical and Expanded Storage Swaps
