What is the primary feature of Storage vMotion?

The primary feature of Storage vMotion is that it allows for the migration of running virtual machines from one datastore to another without any downtime. This capability is essential for maintaining service availability while performing storage maintenance, load balancing, or optimizing resource allocation. With Storage vMotion, virtual machines can seamlessly move data without the need to shut them down, ensuring continuous operation and improved efficiency in managing storage resources.

This feature is particularly valuable in environments where uptime is critical, as it minimizes disruptions. Administrators can perform storage tasks, such as upgrading storage systems or reallocating resources, effectively without impacting users or applications. The ability to move virtual machine disk files while they are active highlights the technology's robustness and flexibility in managing virtual infrastructure.
