Dynamically changeable virtual mapping scheme
First Claim
1. A stored data management subsystem, the stored data management subsystem comprising:
- one or more hosts; and
a plurality of data storage elements functionally coupled to the one or more hosts, wherein the plurality of data storage elements is organized using a plurality of layers of mapping tables, the plurality of layer of mapping tables provides unique identification of a location of data such that individual data entries in a mapping table is variable and self-defining with respect to the amount of data managed.

Abstract
A system is provided to support dynamically changeable virtual mapping schemes in a data processing system. The present invention separates processing of data unit requirements from the selection of which storage subsystems to use for storage by using a storage methodologies inventory. A stored data management subsystem contains one or more hosts. A plurality of data storage elements is functionally coupled to the one or more hosts. The plurality of data storage elements is organized using a plurality of layers of mapping tables. The plurality of layers of mapping tables provides unique identification of location of the data such that individual data entries in a mapping table is variable and self-defining with respect to the amount of data managed.
