vmware vmotion Introduction VMware vSphere vMotion enables the live migration of virtual machines from one VMware vSphere 5 host to another, with no perceivable impact to the end user. vMotion is a key enabler of a number of VMware technologies, including vSphere Distributed Resource Scheduler (DRS) and vSphere Distributed Power Management (DPM). vMotion brings invaluable benefits to administrators—it helps prevent server downtime, enables troubleshooting and provides flexibility. Although vMotion has been used successfully since the earliest versions of VMware ESX, vSphere 5 incorporates a number of performance enhancements to make it easier than ever to enable vMotion on even the largest virtual machines running heavy-duty, enterprise-class applications, with minimal overhead. This white paper presents a brief description of the vMotion technology, performance enhancements in vSphere 5, and performance implications of this technology with data from a wide variety of Tier 1 application workloads. It also presents the data that quantifies the performance differential between vSphere 5 and vSphere 4.1. Finally, it describes several best practices to follow when using vMotion.
