Data Domain unveils new deduplication storage system

Offers both NetBackup OpenStorage and virtual tape library as software options

By CBR Staff Writer

Data Domain, has introduced DD880, a new performance inline deduplication storage system for enterprise backup and archive applications.

The company claims that the new deduplication storage system has an 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 databases in short backup windows.

Data Domain said that its new storage system supports up to 71 TB of associated addressable, post-RAID, pre-deduplication disk storage. A configured Data Domain DDX Array with 16 DD880 controllers reportedly improves aggregate throughput performance to up to 86 TB/hour and offers up to 56 petabytes of usable capacity, offering the capability for online retention to consolidated data centres.

According to Data Domain, the new storage system deduplicates data inline using an approach in which throughput is gated by factors that are CPU-centric, not disk centric. The new storage system’s price/performance is enabled by the Data Domain SISL (Stream-Informed Segment Layout) scaling architecture to minimise the number of disk accesses required in the deduplication process.

The new storage system supports NFS and CIFS by default, and offers both NetBackup OpenStorage and VTL as software options.

With the Data Domain Replicator software option, the new storage system can automate WAN vaulting for use in disaster recovery (DR), remote office backup, or multi-site tape consolidation. Also with the Data Domain Retention Lock software option, archive data will be locked for increased governance control or shredded when required to meet Department of Defense (DoD) and National Institute of Standards and Technology (NIST) specifications, the company said.

The company further added that the new storage system also includes green storage efficiency and features Data Domain Data Invulnerability Architecture that defends against data integrity issues by providing verification during storage and recovery of data.

The company also released its Enterprise Manager, a new graphic user interface (GUI)-based management infrastructure for Data Domain systems. Enterprise Manager provides monitoring or configuration support for system features including centralised management of multiple nodes and configuration of system replication and migration capabilities.
