zero-downtime maintenance. If a physical server needs servicing, it can be vacated; that is, all running VMs are moved to other ESX Server systems without affecting users. The vacant system can be shutdown, repaired, then placed back into service at which time VMs can be migrated back to it – all without impacting availability to end users.

Dell configurations of ESX Server software and VirtualCenter allow users to:

•Implement server consolidation

•Deliver high availability and guaranteed service levels

•Streamline testing and deployment

•Scale hardware and software infrastructure

•Upgrade to current and standard hardware, independently of software upgrades
