Summary :
This SAP Note provides directions for optimizing SLES 11 SP3 or SLES 11 for SAP SP3 for use with SAP Hana. Key recommendations include disabling transparent hugepages to avoid performance issues unique to HANA's memory management, configuring C-States for lower latency to improve performance for applications sensitive to execution time, and using specific PTF kernels from SUSE for XFS improvements. It advises updates like the GlibC update for stability in HANA operations. Users must have root access to implement these changes, and adjustments might vary with system configurations and future updates.
