This article is part of the Vol. 9 Num. 10 February 2011 issue of Storage magazine
Global data deduplication can yield significant capacity savings, but its most attractive feature may be the architecture it's built upon. The buzz around data deduplication continues unabated. Based on our experience, many IT users have already deployed data deduplication to some extent in their data centers. And many of those who haven't taken the dedupe plunge are planning to in 2011. Still, we estimate that only approximately 20% of worldwide enterprise data is protected on disk, with another 50% still to be added to that number. The rest will stay on tape or remain unprotected. But even as shops enjoy the benefits of dedupe, some are beginning to worry about the proliferation of secondary disks. And many of those are wondering if global deduplication might actually deliver more efficiency across large amounts of data. But before we get into global data deduplication, let me define data deduplication itself, especially in contrast to primary storage optimization (PSO).
