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

A single server can be used in a "stand-alone" mode, or one or more servers can be connected to a shared SAN through a switch. VMotion technology is available when two or more servers share a common SAN. VirtualCenter may be used to manage servers in any of these configurations, and is required to i
