EMC Data Domain DD890

• Deduplication storage for backup and archive

EMC Data Domain deduplication storage systems continue to revolutionize backup, archiving, and disaster recovery with high-speed, inline deduplication.

Fast Inline Deduplication
	Data Domain systems provide throughput up to 31 TB/hour, enabling more backups to complete sooner, reducing pressure on backup windows. EMC Data Domain systems deduplicate data inline during the backup or archive process, which maximizes backup performance and minimizing disk storage requirements. The deduplicated data can also be replicated over the WAN to a remote site for disaster recovery operations, eliminating the need for tape-based backups, or for consolidating tape backups to a central location. Data Domain systems provide flexible replication topologies to optimize your backups, such as full system mirroring, selective, bi-directional, many-to-one, one-to-many, and cascaded. Data Domain Systems provide the capability to co-locate both backup and archive workloads on the same infrastructure allowing greater consolidation by eliminating silos of storage and asscoated overhead. The key to enabling industry leading performance while minimizing disk requirements is the EMC Data Domain Stream-Informed Segment Layout (SISLTM) scaling architecture. Specifically, SISL leverages the continued advancement of CPU performance to continuously increase Data Domain system performance by minimizing disk accesses required to deduplicate data. SISL deduplicates data inline by identifying duplicate data segments in memory, which minimizes disk usage. This enables Data Domain system throughput to be CPU-centric.
Scalable deduplication storage
	By reducing backup and archive storage requirements by 10 to 30x, Data Domain systems can help significantly reduce the storage footprint for a typical enterprise data set. With deduplication, multiple months of retention on disk is possible using the same number of “floor tiles” that would traditionally provided only a couple of days of disk staging.
Data Invulnerability Architecture
	Data Domain systems are designed as the storage of last resort – built to ensure you can reliably recover your data with confidence. The EMC Data Domain Data Invulnerability Architecture is built into every Data Domain system to provide 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. In addition, continuous fault detection and self-healing ensures data remains recoverable throughout its lifecycle on a Data Domain system.
