The Data Domain system derives its performance advantages from the EMC Data Domain Stream-Informed Segment Layout (SISLTM) scaling architecture. This CPU-centric approach minimizes the number of disk spindles required to achieve the throughput performance needed for critical single-stream operations. Data Domain system stores unique data sequence only once and save significant physical storage capacity by substituting small references for identical redundant sequence, enabling cost-efficient retention on disk for fast, reliable recoveries. Snapshot technology further enables extended local and off site retention on disk.
The Data Domain appliance series is qualified with excellent enterprise backup software and archiving applications and easily integrates into the existing storage infrastructure without change for either data center or distributed office data protection.
