EMC Reveals New Data Domain Global Deduplication Array
Data Domain claims this new system, dubbed the Global Deduplication Array, is capable of backing up 12.8TB of data per hour (which computes to a 3.5G bps rate), has a top usable capacity of 280TB, and can handle up to 270 concurrent write streams.EMC's Data Domain storage division came out April 12 with a speedy new inline deduplication storage system for enterprise backup applications.
The numbers shout for themselves. Data Domain claims this new system, dubbed the Global Deduplication Array, is capable of backing up 12.8TB of data per hour (which computes to a 3.5G bps I/O rate), has a top-end usable capacity of 280TB, and can handle up to 270 concurrent write streams.
The new inline array distributes parts of the deduplication process to the backup servers in order to reduce network load and increase throughput performance of the GDA controllers, Reidenbach said.
Using EMC Data Domain's Replicator software option, the Global Deduplication Array also can automate wide area network (WAN) vaulting for use in disaster recovery, remote office backup, or multisite tape consolidation, Reidenbach said.
"Figuring out how to get backups done within the allotted period of time in the face of data growth is still the biggest data protection challenge that organizations face according to our research," said Brian Babineau, Senior Consulting Analyst with Enterprise Strategy Group.
"With their Data Domain Global Deduplication Array, EMC has far exceeded the inline deduplication performance benchmark it set with its previous top-of-line Data Domain system, but more importantly, the company has given customers a way to protect more of their data in a shorter period of time.
"We expect more companies to evaluate integration between backup software and deduplication storage to maximize these performance levels and data reduction results while consolidating administrative tasks."
EMC also announced enhanced features for the regular DD880 arrays, including a new encryption software option designed for data at rest and new replicator features for systems with thin wires.
The DD880, Data Domain's top-of-the-line array, now features a doubled top capacity (142.5TB usable from 71TB previously), Reidenbach said.
The EMC Data Domain Global Duplication Array will be generally available in Q2 2010.
