z/OS support for the IBM TotalStorage enterprise storage server
Abstract
The IBM TotalStorage™ Enterprise Storage Server® provides unique capabilities for eServer™ zSeries™ and S/390® environments. We describe two such capabilities, Parallel Access Volume and I/O Request Priority, and discuss the algorithms and mechanisms used to implement and manage them. We show how the new functions deliver significant value to customers, particularly in the areas of self-optimizing management of resources tied to customer goals and reduced customer configuration planning.
