Exploring the I/O Performance Characteristics of Intel Based FLEX-ES Servers for z/OS~1

摘要

As a result of the continuing evolution of z/Series processors, an ever widening gap has developed between the minimum size of IBM's entry level processors and the MIPS requirements of small z/OS software developers as well as the thousands of VSE and VM installations. This paper explores the architecture of the FLEX-ES product from Fundamental Software Incorporated (FSI) as delivered in the iDev member of Cornerstone Systems' iFrame product family. Specific attention will be paid to the evaluation of the performance provided by the FLEX-ES I/O subsystem.
