Deduplication Eases Storage Woes

Arthur Cole

Your enterprise keeps generating more and more data, the vast majority of which has to be stored for business, legal and other purposes. Fortunately, storage costs, both capital and operational, are dropping.


Sounds like a non-issue? Not really, because as most of you are well aware, storage is only half the battle. There are data management, acquisition, recovery and a host of other issues that require both improvements in storage capabilities and a reduction in the amount of data to be stored.


Much of the industry right now is focused on data deduplication as an effective means of lessening the burden on storage and retrieval. just ran a strong piece spelling out the basics of deduplication and how it can lessen the strain on whatever storage media you happen to be using. It's a good place to start if you're pondering the difference between file, block and bit deduplication, or if your vendor is tossing terms like "hash collisions" at you.


And speaking of vendors, there's been a fair amount of jockeying for position in the dedupe market ever since EMC signaled its intentions to get in on the action last fall with the purchase of Avamar Technologies. Not only did the move fill out EMC's storage lineup, it gave the company instant access to the list of Fortune 50 customers that Avamar counts as clients.


Last week saw two key developments, the first being Quantum's release of the StorNext 3.0 system, which uses deduplication as a means to efficiently move data across various storage tiers. By blocking the transfer of redundant data from place to place, Quantum aims to cut down on the amount of redundant data that builds up in the first place.


The other significant move was the tie-up between Data Domain and Luminex Software, a union that should produce a unique approach to deduplication on disk-based systems. Putting Luminex' Channel Gateway system on Data Domain's backup appliances is aimed at providing advanced data protection and management to enterprises looking to rid themselves of tape storage.


The basic lesson in all this is that falling storage costs should not be used as a crutch for your growing storage needs. A more efficient data environment is a more optimal solution going forward.
