New High-Performance Data Domain Dedupe
EMC expanded its Data Domain line of deduplication appliances with its new Global Deduplication Array (GDA), which incorporates two of EMC's new Data Domain DD890 controllers. The two DD890 controllers each have their own storage capacity, which in the GDA is linked as a single pool of storage.
The GDA has a logical capacity (post-dedupe) of up to 28.5 petabytes, and features performance of 26.3 TBs per hour, or seven times that of IBM's ProtectTIER dedupe system, according to EMC. The GDA supports EMC's Data Domain Virtual Tape Library option, as well as several top backup applications including Tivoli TSM.
