NetApp’s initial bid for Data Domain came as a surprise to many. EMC’s counter was even more of a shock. These discussions have very important implications for data protection and deduplication. Two thoughts immediately come to mind:
It’s hard to do deduplication well.
EMC and NetApp say that they have robust deduplication solutions in their DL3D (Quantum technology) and NearStore VTL series products. Before these negotiations, you might have believed them. Now, they are both bidding aggressively on Data Domain. What does that say about their confidence in their own solutions? Remember, these are large companies with hundreds (thousands?) of engineers with storage experience. Why wouldn’t they just build their own deduplication technology? The simple answer is that developing really good, enterprise-class deduplication technology is difficult.
