Summary
- The range of relative capacity for a particular application is workload and hardware architecture dependent
- The relative capacity range is approximately the same for Linux on the platform as it is for UNIX System Services
- Server Consolidation or mixed workload configurations can exploit S/390 functions for more efficient use of hardware resources
- OS/390 or z/OS: WLM management
- Linux : unique functions (LPAR, VM, and VIF)
- Certain applications will not scale without reengineering, regardless of platform
- Certain UNIX applications can perform well under Linux for little or none of the reengineering required to exploit OS/390 or z/OS efficiently
- Capacity Planning support available through IBM support channels
