Data duplication is white hot again this week as Data Domain and Spectra Logic introduced new products and features.

Data Domain, who many in the industry say leads in data deduplication, announced a new high-end controller for inline, rather than post-processing, deduplication. The DD690 gives aggregate throughput of 1.4TB/hour and single stream throughput of 600GB/hour. The DD690 can be paired with Data Domain’s DDX Arrays to offer 28PB of useable capacity. With this throughput and capacity, the Data Domain products allow realistic protection for large databases and long-term online retention for enterprise data centers.

The DD690 uses the Stream-Informed Segment Layout (SISL) architecture to reduce the number of disk accesses required by deduplication. The control is a dual-socket model that attaches to Serial ATA-based storage.

Using the Data Domain Replicator Software, the DD690 can support fan-in of data from as many as 60 remote offices. It will be available this quarter.

Tape and data protection vendor Spectra Logic also announced that it will integrate FalconStor’s virtual tape library and deduplication technology into its nTier Intelligent Secondary Storage (ISS) appliances. This product will let the nTier disk-based backup function as a backup target and reduce the amount of redundant data that is being stored. (Compare Data Backup and Replication products)

The VTL and deduplication will span all the nTier appliances – the nTier300, 500 and 700 – which scale from 10TB to 600TB. Spectra nTier Deduplication is shipping and starts at $12,500.
