Description:

This paper studies the performance of a large Oracle RAC instance on vSphere 5 when compared to a similar physical environment. The results reveal that Oracle RAC, when virtualized with vSphere 5, performs within 7% of a corresponding physical environment. This information encouraged EMC IT to use vSphere to support their production Oracle RAC databases. This paper also provides best practices implemented while examining the performance of Oracle RAC on vSphere 5. Customers can use this information to optimize their own installations.
