An administrator is tasked with evacuating a storage array because it has been replaced. Which feature meets this requirement?

The correct answer is Storage vMotion, as it specifically allows for the migration of virtual machine disks from one storage array to another while the virtual machine remains powered on. This functionality is essential for tasks such as evacuating a storage array because it ensures that the virtual machines can continue to operate uninterrupted even while their data is being transferred to a new storage solution.

Storage vMotion can handle the movement of disk files without requiring downtime, making it an effective tool for administrators looking to replace or upgrade storage resources. This capability is crucial in maintaining service availability and minimizing downtime during the transition process.

Other features such as vSphere vMotion are designed for moving virtual machines between physical hosts rather than focusing on storage. Proactive HA functions to automatically migrate virtual machines based on host failure predictions, and Predictive DRS provides resource management based on historical usage patterns but does not directly support storage migration tasks. Therefore, these functionalities do not fulfill the specific requirement of evacuating a storage array.
