Storage virtualization has been around for several decades. While technologies have advanced and capabilities have become more sophisticated over time, the motivations for virtualizing resources and the anticipated benefits have remained relatively stable. Storage virtualization continues to be an important topic because it addresses a number of significant challenges. Storage vendors, the media, and other sources expound on virtualization's merits in ways that might lead one to conclude that the term has a single, agreed-upon meaning and value-that perhaps one size fits all. Indeed, the range of storage virtualization technologies and solutions has continued to evolve as storage hardware, the software that powers them, and external storage management applications have matured. This can often create confusion. Customers look to suppliers like HP for guidance and l... [download for more]
