This paper analyzes the five year lifecycle TCO of two alternative platforms, considering the costs to plan, purchase, implement, manage, and use two comparable UNIX server configurations for a specified scenario, application, and workload. The comparisons in this study use HP-UX 11i, a UNIX solution hosted on an open system platform using HP Integrity (Intel Itanium based) servers versus IBM AIX 5L running on proprietary RISC-based IBM eServers and quantifies how open systems UNIX solutions running on Intel Itanium servers can deliver higher levels of manageability, consolidation, virtualization, adaptability, security, and availability.
