Fact 2: Removing just one-third of this duplicate data, could - on an average - save up to USD 1.6 billion on storage energy.
Do the math. Removing it all would mean conservation of storage energy worth approximatel
One million GigaBytes (GBs) make a PetaByte (PB). In 2008, the sale of disk-based storage systems crossed 2500 PBs, growing at almost 60% each year. These figures do not include direct attached storage i.e. hard drives that come pre-loaded with PCs or servers. The overall consumption doubles when this storage is backed up.
On an average, the best solid-state storage consumes about 5 Watts per MegaByte (MB). This puts the total cost of maintaining (cooling + power) a 1 TB hard disk at about USD 2,500 per year.* The annual energy consumption by newly bought storage stands at USD 5 Billion – and there’s still the backing up to consider!
Here’s where DDD comes in. This technology saves just a single copy of duplicate data. Most storage vendors using DDD provide block-level duplicate removal at target i.e. when the data reached the storage.
And this brings us back to Fact 2 viz. an average 30% duplicate data removal can save USD 1.6 billion on storage energy and USD 2 billion on bandwidth costs and backups. Not to mention that duplication also chokes bandwidth and storage.
