摘要

If you're an IT executive, chances are you're already thinking about storage visualization. Nearly one-quarter of companies with at least 500 employees have deployed storage virtualization products already, and another 55% plan to do so within two years, a recent Gartner survey found. Storage virtualization is an abstraction that presents servers and applications a view of storage that is different from physical storage, typically by aggregating multiple storage devices and allowing them to be managed in one administrative console. The technology is emerging fast onto the enterprise scene for good reasons: In many cases, it can reduce the management burdens associated with storage; and offer better models for data-center migrations, backup and disaster recovery Enterasys Networks reaped these benefits recently when it moved a data center from Boston into its headquarters in Andover, Mass.
