SAN and NAS virtualisation boosts availability
In just a few short years storage virtualisation, also known as block virtualisation, has proven its worth in the large enterprise, having travelled that well-worn path from pricey boutique solution to affordable commodity. As a standard feature in all but the most modest mid-tier storage arrays, storage virtualisation soothes a wide range of storage management woes for small and mid-size organisations. At the same time, dedicated solutions from top-tier vendors deliver the greatest ROI to large shops managing large SANs with intense data availability requirements.
