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.

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).
