BANGALORE, INDIA: Data Domain, provider of deduplication storage systems, announced the Data Domain DD880, an inline deduplication storage system for enterprise backup and archive applications.

With aggregate throughput up to 5.4 TB/hour, faster per controller than conventional virtual tape library (VTL) systems, and single-stream throughput up to 1.2 TB/hour to enable protection of large databases in short backup windows, the DD880 system supports up to 71 TB of associated addressable, post-RAID, pre-deduplication disk storage.

A fully configured Data Domain DDX Array with 16 DD880 controllers increases aggregate throughput performance to up to 86 TB/hour and offers up to 56 petabytes of usable capacity, delivering the capability for long-term online retention to large, consolidated data centres.

Unlike most VTL systems or other backup storage targets, the DD880 deduplicates data inline using an approach in which throughput is gated by factors that are CPU-centric, not disk centric. The DD880's price/performance is enabled by the Data Domain SISL(TM) (Stream-Informed Segment Layout) scaling architecture to minimize the number of disk accesses required in the deduplication process.

Brian Babineau, sr. analyst, Enterprise Strategy Group, said: "There has been a popular misconception that inline deduplication systems cannot ingest backups as fast as backup solutions that write directly to disk and then execute data reduction processes. Maybe that was true at one point in time, or for specific implementations. Data Domain's DD880 clearly proves that inline deduplication can be highly competitive in speed, even when compared to VTLs and other disk based backup targets with no deduplication at all."

Also available is a new release of Data Domain Enterprise Manager, a graphic user interface (GUI)-based management infrastructure for Data Domain systems. Enterprise Manager now provides monitoring or configuration support for many system features including centralized management of multiple nodes and configuration of system replication and migration capabilities.

The DD880 will be generally available in the third quarter of 2009.
