Refresh - Unique SAP HANA on Power capabilities for Green Computing
P9 is the only processor architecture supported for SAP HANA workloads using dynamic frequencies for production workload saving energy and cooling cost.
The preference is to use the "Dynamic Performance" mode. It will lower the processor frequency if the entire processor socket is idle for 100s of milliseconds, thus, providing both a performance boost and a power savings when possible. Dynamic Performance mode is great for customers that want deterministic performance across the full range of environmental conditions or those that have acoustic or power consumption concerns.
Alternatively the "Nominal" (constant lower CPU frequency) or "Maximum Performance" can be used for SAP HANA production instances.
