EMC has overhauled Data Domain's entry-level and midrange deduplication systems with the release of the DD630, DD610 and DD140, a new batch of disk-based backup systems that offer more performance and capacity than previous models.
The DD630 and DD610 appliances feature up to 1.1TB/hour and 675GB/hour of inline deduplication throughput, respectively – double the performance of the models they are replacing, the DD530 and DD510.
The DD600 series also boasts more storage capacity. The DD630 supports up to 420TB of logical capacity and the DD610 houses up to 195TB.
The DD630 and DD610 support the same software and storage protocols as the rest of the Data Domain product family, including NFS, CIFS, Symantec's NetBackup OpenStorage (OST) and virtual tape library (VTL) as software options.
The appliances are also compatible with backup and archiving applications from Atempo, BakBone, CA, CommVault, EMC, HP, IBM, Microsoft and Symantec.
EMC is also replacing the entry-level DD120 with a bigger, faster model for remote locations. Like the DD600 series, the new DD140 packs a 100% performance increase and more capacity than its predecessor. The DD140 ties into larger Data Domain systems such as the DDX Array to feed recovery images back to a central data center for disaster recovery.
The DD140, DD610 and DD630 are designed for edge sites that store backup or archive data locally for rapid restores and replicate it via a WAN to a hub for long-term storage. According to Brian Biles, vice president of product management, the majority of Data Domain systems are deployed with the Replicator option, which enables cross-site deduplication for many-to-one or, more recently, cascaded replication topologies.
The DD600 Series supports replication fan-in from Data Domain systems installed at up to 90 remote offices. The architecture allows for deduplication across all of the remote sites, which minimizes bandwidth requirements.
The appliances offer an average of 10:1 to 30:1 data reduction for enterprise recovery images, according to the company.
