What term describes the process of pooling physical storage from multiple network storage devices so it appears as a single storage device?

• A. Storage Virtualization
• B. Storage Pooling
• C. Disk Aggregation
• D. LUN Aggregation

Answer: (A)

Pooling physical storage from multiple network storage devices to appear as a single storage device is storage virtualization. It creates an abstraction layer between the hardware and the hosts, combining disks from different devices into a single managed pool and presenting one or more logical units to clients. This makes provisioning, resizing, and migrating storage easier and more flexible without worrying about the concrete physical disk layout. Storage pooling is related and can be part of virtualization, but by itself it doesn’t necessarily imply presenting a single device to the host. Disk aggregation or LUN aggregation are less standard terms and don’t fully describe the seamless single-resource presentation that virtualization provides.
