Considerations for Transitioning Highly Available Applications to System z

System z capacity planning, sizing, and TCO

This chapter discusses aspects of sizing and capacity planning on System z. The studies are based on industry experience, knowledge of machine architectures, current environment and performance metrics (if an application is being moved from distributed systems to IBM System z), or raw data specification (if an application is being sized “from scratch”).

Sizing involves a combination of “art and science” wherein practitioners use their skills and experience to convert real or estimated performance data ...
