Eliminate application downtime from planned server maintenance by migrating running virtual machines between hosts.
vSphere with Operations Management combines the world’s leading virtualization platform with VMware’s award winning management capabilities. This new solution enables IT to gain operational insight into the virtual environment providing improved availability, performance, and capacity utilization. Run business applications confidently to meet the most demanding service level agreements at the lowest TCO.
vSphere vMotion enables the live migration of running virtual machines from one physical server to another with zero downtime, continuous service availability and complete transaction integrity. vMotion is a key enabling technology for creating the dynamic, automated and self-optimizing datacenter.
Move Entire Running Virtual Machines Instantly vMotion technology, deployed in production by 80% of VMware customers*, leverages the complete virtualization of servers, storage and networking to move an entire running virtual machine instantaneously from one physical server to another. The virtual machine retains its network identity and connections, ensuring a seamless migration process. You'll be able to:
Manage and Schedule Live Migrations with Ease The migration wizard lets you easily benefit from the reliability and manageability derived from a production-proven product used by thousands of customers for years.

Live migration of a virtual machine from one physical server to another with VMware vMotion is enabled by three underlying technologies.
Enhancements to vMotion in vSphere 5.1 provide a new level of ease and flexibility for live virtual machine migrations. Prior to vSphere 5.1, both vMotion and Storage vMotion required shared storage to perform live migrations of virtual machines. (vMotion required shared storage between hosts performing the vMotion. Storage vMotion required a host to have access to the source and destination datastores.) vSphere 5.1 removes the shared storage requirement.
vSphere 5.1 enables a virtual machine to change its datastore and host simultaneously, even if the two hosts don't have any shared storage in common. It allows virtual machine migration between clusters in a larger datacenter, which may not have a common set of datastores between them but also allows virtual machine migration in small environments without access to expensive shared storage equipment.
vSphere 5.1 allows combining vMotion and storage vMotion into one process. This combined migration copies both the virtual machine memory and its disk over the network to the destination host. After all the memory and disk data are send over, the destination virtual machine will resume and the source virtual machine will be powered off.
