Which technology allows multiple storage devices to be presented as a single pool for use by virtual machines or hosts?

• A. Virtual Switch
• B. Virtual HBA
• C. Virtual NIC
• D. Storage Virtualization

Answer: (D)

Storage virtualization pools together many physical storage devices and presents them as a single, manageable pool that can be allocated to virtual machines or hosts. This abstraction lets admins treat diverse disks and arrays as one resource, enabling flexible provisioning, easier growth, and features like thin provisioning and snapshots. In a virtualized environment, the storage pool is accessed over storage networks and carved into virtual disks for VMs, without needing to know the exact physical location of each disk. The other options focus on networking (virtual switch, virtual NIC) or on presenting a storage controller to a VM (virtual HBA), but they don’t create a shared, pooled storage resource. So, the technology described is storage virtualization.
