Data Domain introduces new inline deduplication storage system

Data Domain has announced the DD690, claimed to be the industry's highest performance inline deduplication storage system for backup and other nearline applications. With aggregate throughput up to 1.4 TB/hour, and single-stream throughput up to 600 GB/hour to enable protection of large databases in short backup windows, the DD690 establishes consistently high benchmarks across the spectrum of common data center backup metrics.

A fully configured Data Domain DDX Array with 16 DD690 controllers increases aggregate throughput performance to up to 22 TB/hour and offers up to 28 petabytes of usable capacity, delivering the capability for long-term online retention to large, consolidated data centers.

The DD690'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. Unlike many competing approaches, Data Domain systems ride the price/performance wave of multi-core processor architectures rather than depending on over-provisioned storage subsystems for throughput. As a result, Data Domain systems based on dual-socket controllers and minimum SATA-based storage configurations have improved in throughput by nearly a factor of ten from 2004 (150 GB/hour) to 2008 (1.4 TB/hour).

With the Data Domain Replicator Software option, the DD690 can automate WAN vaulting for use in disaster recovery, remote office backup, or multi-site tape consolidation. A single DD690 system can support a replication fan-in from up to 60 remote offices using smaller Data Domain systems such as the recently announced DD120. The DD690 can deduplicate globally across remote sites, further minimizing required bandwidth since only the first instance of data is transferred across any of the WAN segments.
