This paper provides best practice guidelines for deploying SAP® software solutions on VMware
vSphere 4. These guidelines only provide general recommendations and do not target any specific size or type of SAP solution implementation.
VMware has created separate best practice documents for the individual areas of storage, networking and performance. (See the Resources section for a list of these publications.) SAP also has created a variety of technical notes, published in the SAP Marketplace, for more information about virtualizing SAP solutions on VMware virtual infrastructure. Reference numbers of these notes are identified in this document, and you can refer to these additional technical notes in conjunction with the information provided here.
