Executive Summary

The mainframe market should provide few surprises in 2005. IBM will adhere closely to its stated hardware and software pricing policies and continue to execute on its technology road map. We expect 22% to 25% full-year growth in zSeries revenue for 2004, and anticipate more modest growth in 2005 based on z/OS migration history and other market factors. The zSeries development team continues to focus on driving growth in new application workloads, having successfully addressed some customers' performance and cost-of-ownership concerns regarding new workloads with a combination of technology and pricing initiatives. However, it's not new workloads that drive the bulk of zSeries's growth. What butters the zSeries' bread? Two things: traditional volume increases in large enterprises' legacy workloads and net-new applications that may not reside on the mainframe but attach to legacy systems.
