What is a key benefit of ONTAP's dynamic virtualization engine?

• A. It statically binds volumes to physical disks for predictable performance
• B. It eliminates the need for aggregates altogether
• C. It limits volume growth to predefined aggregates
• D. It allows volumes to be moved, resized, or balanced without disrupting clients

Answer: (D)

Dynamic virtualization in ONTAP decouples the logical storage view from the physical layout, enabling non-disruptive management of volumes. With this engine, you can move a volume to a different aggregate or controller, resize it on the fly, and rebalance data across the system while clients continue to access data. This flexibility is especially valuable for maintenance, capacity planning, and performance tuning because operations can happen without downtime or client interruption. In short, it lets volumes be moved, resized, or balanced without disrupting clients. Static binding to disks, removing aggregates, or capping growth aren’t features of this capability, which is all about enabling online, non-disruptive storage management.
