SAP on VMware is hot but not new in the industry today. Many of us as the IT architect are seeking opportunity from time to time to reduce the IT spending but improving the productivity to the business. I would like to share my experience for SAP on VMware.

SAP always have their internal certify program which certify from software to hardware level to ensure their users are compliance with the application requirement for the SAP deployment. You will see a big range of choice you can choose from the certify list from Unix, Linux to Windows as an example.

At the same time, the latest version of SAP are recommended to run on SUSE Linux Enterprise 10 64 bits with MaxDB 7.5. SUSE Linux 10 is perform as you need on VMware.
