Users test deduplication limits

Data deduplication has the potential to radically change the economics of storage. By storing only unique backup data and maintaining meta data about the duplicates, actual stored data can be reduced by magnitudes, resulting in huge cost savings. That said, early deployments are pushing the boundaries of these products, but not all of them are living up to the hype. By using EMC's Avamar deduplication software, chip giant Qualcomm has cut its backup window from two hours to 15 minutes. That's impressive; but with approximately 50 servers and 6TB to 7TB of stored data, the company's storage environment is fairly small, and Qualcomm isn't convinced the technology will scale the way it would like. "It works fine for 50 to 100 servers, but for 1,000 servers it needs to be more scalable," says Paul Ferraro, storage manager at Qualcomm. The company backs up 5,000 servers, for which Ferraro says Avamar's point-and-click GUI management interface isn't appropriate.

To be sure, the decrease was more of a sign that relief may be on the way for storage managers who have spent the last few years trying to keep up with runaway storage growth.
