EMC has announced an upgrade to the EMC Data Domain midrange and entry-level deduplication storage systems, in an effort to help drive continued scaling of performance and capacity across the entire product line. Similar to the company's Data Domain high-end solutions, the new DD630, DD610 and DD140 systems leverage the power of Data Domain's SISL (Stream Informed Segment Layout) scaling architecture to dramatically increase throughput performance and capacity.

The new DD630 and DD610 appliances offer up to 1.1 TB/hour and 675 GB/hour of inline deduplicated storage throughput, respectively. This doubling of performance enables midsize enterprises to reduce their backup windows by up to 50%. Raw storage capacity also increases by 60% allowing users to protect larger data sets and to provide cost-effective, long-term onsite retention. Up to 420 TB and 195 TB of logical data can be protected in the DD630 and DD610, respectively. Like all Data Domain systems, the DD630 and DD610 support NFS and CIFS by default, and offer both NetBackup OpenStorage (OST) and VTL as software options.

Complementing the new midrange systems, the entry-level DD140 appliance provides a 100% increase in storage capacity and a 50% increase in aggregate backup throughput, the company claims. The new DD140 is simple to deploy and is conveniently packaged with Data Domain Replicator software to enable remote site protection. The DD140 complements all Data Domain systems including the DDX Array Series which can act as a hub for recovery images vaulted efficiently from up to 2,880 smaller sites.

The DD140, DD610 and DD630 systems are designed for edge sites that store backup or archive data locally for rapid restores and replicate it via WAN to a hub for longer term storage or consolidated tape use. 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. Most competitive deduplication systems, either through limited post-process architectures or lack of maturity, are still wrestling with first-generation deduplicated replication issues.

"Data at the edge of corporate networks keeps exploding, and IT governance best practices have encouraged stopping inclusion of tape in those environments over the course of the decade," said Brian Biles, Vice President, Product Management, EMC Backup Recovery Systems (BRS) Division. "When using standard backup software, EMC Data Domain systems continue to be the simplest, most cost-effective and capable solution," he added.
