Summary :
To optimize IBM System x3850 M2 or x3950 M2 (Type 7141) for SAP applications, key BIOS settings must be adjusted. The default BIOS configurations are not ideally suited for SAP workloads, leading to suboptimal performance. To achieve the desired efficiency, access the BIOS main screen via the Configuration/Setup Utility, and navigate to "Advanced Setup" under "CPU Options". Here, disable settings such as PowerExecutive Power Capping and Processor Performance States while enabling the Processor IP Prefetcher for improved OLTP performance. The suggested configurations were identified to enhance performance specifically in the SAP SD 2-tier benchmark testing environment. Adjustments may vary depending on whether the system operates in virtualized settings or other specific conditions.
