HP Disaster Tolerant Solutions Using Continuous Access for HP StorageWorks Enterprise Virtual Array in a VMware Infrastructure 3 Environment

Overview

This paper describes two deployment types of a VMware tolerant solution, based on coupling key VMware features with disaster tolerance functionality of HP StorageWorks Continuous Access EVA. The first solution is most suitable for a campus-wide disaster tolerant implementation and the other is suitable for metropolitan/geographically separated areas. Both deployments provide the business continuity needed to support the desired VMware service levels. The tradeoffs associated with each solution are also explored along with configuration caveats and best practices.
