Mainframe Migration

Scalability of Micro Focus Enterprise Server and Microsoft Windows Server 2003

WinHEC 2005 Version - April 20, 2005

Abstract

The paper analyzes the performance of mainframe style workloads on large, multiprocessor Microsoft® Windows® Server™ 2003, Datacenter Edition environments.  We look at a benchmark workload that simulates much of the CPU and I/O behavior of IBM mainframe COBOL and Customer Information Control System (CICS) transaction processing environments.

This benchmark application was measured on an IBM mainframe environment and then, using the Micro Focus Lift and Shift™ process, moved without code modification to the Micro Focus® Net Express™ Enterprise Server with the Mainframe Transaction Option (MTO) on 8-, 12- and 16-CPU processor systems.  

This study by Electronic Data Systems (EDS), Micro Focus, Microsoft, and Unisys Corporation estimates the equivalent of 1,715 mainframe millions of instructions per second (MIPS) for an 8-CPU enterprise-class system.  Further, we show COBOL performance scales linearly under Microsoft Windows similar to what is expected in IT data centers.

This information applies for Microsoft Windows Server 2003.
