What is storage virtualization and one common use case?

• A. Storage virtualization pools physical storage from multiple devices into a single logical storage pool; common use cases include easier management and improved utilization in data centers.
• B. Storage virtualization duplicates data to increase redundancy.
• C. Storage virtualization converts SSD to RAM.
• D. Storage virtualization is only used for personal USB drives.

Answer: (A)

Storage virtualization abstracts multiple physical storage devices into a single, logical pool. This lets administrators manage storage from one place, provision new volumes quickly, and move or balance data without worrying about where it sits physically. The common use case is in data centers, where disks from different servers or storage systems are pooled together to provide flexible, scalable storage. This improves utilization by making it easier to allocate space where needed and reduces fragmentation of resources. Duplicating data to increase redundancy is data replication or RAID, not virtualization. Converting SSD to RAM describes caching or memory-tiering, not storage virtualization. And virtualization isn’t limited to personal USB drives; it’s a broader technique used in enterprise storage.
