Summary :
This SAP Note outlines optimal setup configurations for VMware vSphere when deploying SAP applications. It extends support to VMware ESX 3.5, vSphere 4.x, and 5.x, and emphasizes the importance of using the latest processor technologies to enhance performance, particularly Intel XEON and AMD Opteron series. Important configurations include utilizing a maximum of 2 vCPUs initially and considering resource pools for balanced CPU usage across VMs. For database management, multiple VMFS volumes, separation of log and database files, and usage of multiple virtual SCSI controllers are recommended. Furthermore, the adaptation of the "eagerzeroedthick" format for virtual disks and paravirtual SCSI controllers improves I/O operations and network performance respectively. SAP strictly advises against memory over-commitment and provides guidelines to ensure robust performance within a virtualized environment.
