Enterprise data growth is in large measure fueled by a persistent redundancy caused by sharing and evolving the underlying data. Data Domain storage seamlessly filters out these repeated data patterns while the data is making its way to disk, thereby drastically reducing the capacity foot print needed to store and protect application data. Our progress in Q4 reflects increasing penetration and acceptance of this new class of storage in enterprise data centers around the world.”
