SCALABLE DEDUPLICATION STORAGE
A single EMC Data Domain DD890 system achieves single-stream throughput of up to 1.44TB/hour—performance that is imperative for protecting large, business critical databases in the data center. The DD890 provides aggregate throughput of up to 14.7 TB/hour using multiple backup policies. Data Domain systems store each unique data sequence once and save significant physical storage capacity by substituting small references for each identical redundant sequence.
The DD800 series offers an average of 10 to 30 times backup storage reduction, enabling cost efficient retention on disk for high-speed recoveries. Using the EMC Data Domain Extended Retention software option, customers can leverage the DD860 for long-term retention of backups on disk and minimize reliance on tape infrastructure. Using DD Extended Retention software with the DD860 provides up to 28.5 PB of logical capacity for long-term backup retention.
The Data Domain DD800 series is qualified with leading enterprise backup and archiving applications and easily integrates into your existing storage infrastructure, requiring no changes to data center infrastructure or distributed office backup and archiving policies.These systems support simultaneous data access methods through NFS and CIFS file service protocols over Ethernet, or as a disk-based target using application-specific interfaces such as EMC Data Domain Boost. DD Boost enables advanced integration for environments with EMC Avamar®, EMC NetWorker®, EMC Greenplum®, Oracle RMAN, Quest vRanger, and Symantec Open Storage. Users can leverage the same DD800 series system for both backup and archive workloads. This improves the efficiency across backup and archive applications and data types, as well as reduces management overhead by combining multiple applications’ storage on a single system.
MULTISITE DISASTER RECOVERY
EMC Data Domain Replicator software enables network-efficient and encrypted replication to a remote site for disaster recovery, remote office data protection, or multisite tape consolidation. The DD890 supports replication fan-in from Data Domain systems installed at up to 180 remote offices. Cross-site deduplication minimizes the required bandwidth between all sites, since only the first instance of data is transferred across any of the WAN segments. Data sets are effectively shrunk by 99 percent, to a size where network-efficient replication is fast and reliable. If confidentiality is required, deduplicated and compressed data can be encrypted in-flight when being replicated between Data Domain systems,independent of the replication topology used.
ULTRA-SAFE STORAGE FOR RELIABLE RECOVERY
The EMC Data Domain Data Invulnerability Architecture provides the industry’s best defense against data integrity issues. Inline write and read verification protects against, and automatically recovers from, data integrity issues during data ingest and retrieval. Capturing and correcting I/O errors inline during the backup process eliminates the need to repeat backup jobs, ensuring backups complete on time and satisfy service-level agreements. Unlike other enterprise arrays or file systems, continuous fault detection and self-healing features protect data throughout its life cycle on all Data Domain systems.
