Overview: Storage virtualization has been around for several decades. Virtualization is the aggregation of physical resources into a unified structure (""Pool""), and the presentation of those resources as capabilities that can be consumed by applications, desktop clients, or other types of storage clients. The term ""Virtualization"" has really become an umbrella that encompasses a vast array of encapsulation and management technologies and implementation methods. This paper describes the business motivations for storage virtualization and the benefits it can deliver. Basic storage virtualization approaches are described and their benefits and limitations are compared. Finally, the HP StorageWorks virtualization strategy is described.
