Storage vMotion has several uses in administering your vSphere environment.
- Upgrade ESXi without virtual machine downtime in situations where virtual machine disks must be moved to shared storage to allow migration with vMotion.
- Perform storage maintenance and reconfiguration. You can use Storage vMotion to move virtual machines off a storage device to allow maintenance or reconfiguration of the storage device without virtual machine downtime.
- Redistribute storage load. You can use Storage vMotion to manually redistribute virtual machines or virtual disks to different storage volumes to balance capacity or improve performance.
