Definition

Storage virtualization is technology to build logical storage using physical storage devices. More precisely, SNIA defines storage virtualization as follows:

  1. 1.

    The act of abstracting, hiding, or isolating the internal function of a storage (sub) system or service from applications, compute servers or general network resources for the purpose of enabling application and network independent management of storage or data.

  2. 2.

    The application of virtualization to storage services or devices for the purpose of aggregating, hiding complexity or adding new capabilities to lower level storage resources.

  3. 3.

    Storage can be virtualized simultaneously in multiple layers of a system, for instance to create hierarchical storage manager like systems.

Key Points

Storage virtualization is used to provide an aggregation of data blocks (a logical volume) to applications running on servers. This aggregation of blocks may reside on a single storage device, may be spanned across multiple devices...
