Summary :
This SAP Note offers guidance for setting up servers with VMware vSphere specifically tailored for SAP applications. Key recommendations include using the latest processor generations which support features like EPT and R-Values for enhanced VM performance. It's advised to begin with VMs having one or two vCPUs and scale up as necessary. Resource pools should be utilized for better CPU resource allocation across VMs. Separate VMFS volumes, multiple SCSI controllers, and specific disk formats are recommended for optimized database operations. Network and memory configurations also play crucial roles in achieving optimal performance and system stability in a virtualized SAP environment. The use of PVSCSI and vmxnet3 enhances throughput and network efficiencies. Avoid memory over-commit and adhere strictly to memory reservation settings to support SAP's memory allocation framework. Lastly, regular synchronization and kernel adjustments are necessary to prevent system errors and maintain performance.
