Protecting Business-Critical Applications in a Vmware Infrastructure 3 Environment

This paper presents several fundamental criteria for evaluating HA/DR solutions and reviews the components, architecture, and functional characteristics of two that are designed to protect critical applications on VMware ESX: VMware HA and Symantec Veritasâ„¢ Cluster Server for VMware ESX.

This paper begins with a brief overview of the problems of high availability (HA) and disaster
recovery (DR) in the virtual environment. Due to server clustering, outages have the potential to
affect many servers at once, possibly causing a corresponding failure among many mission-critical
applications.
