* Vmotion
VMware VMotion use to migration of your virtual machines from one physical server to another. with continuous service availability.
VMotion requirement
The hosts must be running ESXi 5.1 or later.
The hosts must meet the networking requirement for vMotion. See vSphere vMotion Networking Requirements.
Virtual machine disks must be in persistent mode or be raw device mappings (RDMs).
The destination host must have access to the destination storage.
Consider the limits for simultaneous migrations when you perform a vMotion migration without shared storage. This type of vMotion counts against the limits for both vMotion and Storage vMotion, so it consumes both a network resource and 16 datastore resources.
