NEC makes deduplication application-aware

By Kevin Komiega

-- NEC this week announced the availability of application-aware deduplication, a new feature of its HYDRAstor grid storage platform that squeezes inefficiencies out of the data stream and boosts data reduction ratios.

The application-aware deduplication technology analyzes incoming data streams in search of application-level metadata. Once identified, the metadata, which tends to have a negative impact on deduplication rates, is filtered from the data and processed separately in an effort to speed backups and archiving operations.

Gideon Senderov, director of product management at NEC, says application-aware deduplication overcomes the scale, scope and capacity limitations inherent to traditional deduplication systems by removing "non-user" related data in the data stream.

"Application metadata interleaves with user data and makes the underlying data look different. The application metadata tends to stymie the deduplication process," says Senderov. "Our application-aware global deduplication filters the metadata from the user data inline and processes it separately."

Senderov claims internal tests show an improvement in data reduction ratios of up to 130% when compared to "generic" deduplication.

The addition of application-aware deduplication to the HYDRAstor storage platform is included under HYDRAstor's software maintenance agreement and is offered at no additional cost. 

The application-aware deduplication feature is available now with initial support for CommVault's Simpana and Symantec's NetBackup software. NEC will add support for additional backup and archiving applications over time.
