Definition

Storage virtualization is technology to build logical storage using physical storage devices. More precisely, the Storage Networking Industry Association (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, computer 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...
