zAAPs and zIIPs: Increasing the strategic value of System z

Abstract

With the addition of IBM System z™ application assist processors (zAAPs) and integrated information processors (zIIPs) to the portfolio of special-purpose IBM System z processors, the reinvention of the IBM mainframe continues. Jointly, zAAPs and zIIPs provide significant IBM System z9™ integrated and cost-effective processing cycles for today's strategic Java™ and DB2® for z/OS® programming platforms which are increasingly fundamental to enterprise-class business environments. Overviews of zAAPs and zIIPs are presented that describe their functionality, design, and use by the z/OS operating system to achieve the execution of both Java and z/OS DB2 programming functions. ©Copyright 2007 by International Business Machines Corporation.
