First generation deduplication systems focused on saving storage. Nexsan and FalconStor are redefining what you expect from a deduplication solution by delivering an ultra-efficient system that saves more than just capacity. DeDupe SG is faster to save time on backup and restore, greener to save energy between backups, simpler to save management resources and more dense to save space. Introducing DeDupe SG, the only highly efficient deduplication solution. By uniquely delivering "SG" - Speed with Green - DeDupe SG edges out the competition in performance while offering significant energy savings during idle times.

DeDupe SG™ is a complete, turn-key solution with all the necessary software and hardware leveraging Nexsan’s highly efficient storage combined with FalconStor’s high performance deduplication software engine (File-interface Deduplication System - FDS). DeDupe SG represents the next generation in data deduplication by reducing capacity costs while greatly improving operational efficiency.

DeDupe SG delivers performance that is 20% to 100% faster than competitive vendors by combining the latest high speed CPU processing technology with Nexsan’s high speed RAID subsystem. Not only is it faster, DeDupe SG is smarter by first writing and storing backups on its high speed disk cache (deduping at a later time or concurrently) so that backup tasks are completed in a fraction of the time.

DeDupe SG flexes its strength as the only highly efficient deduplication storage system. DeDupe SG doesn't just deliver speed, it delivers green. The typical backup window is 2-8 hours a day, yet all other dedupe solutions spin disks at full speed for the remaining 16-22 hours. By leveraging the green efficiencies inherent to Nexsan storage components and energy saving AutoMAID™ technology, DeDupe SG users not only get better performance during their backups, they save energy and reduce costs every hour the system is not in use - 65% savings when compared to other dedupe solutions and 95% when compared to normal disk storage.

DeDupe SG Advantage:

With growing capacity needs, shorter backup windows, escalating energy costs, shrinking datacenter space, tighter budgets and the need for faster restore, IT professionals need a new kind of deduplication solution. It’s not just about saving storage anymore. It’s about saving time, energy, space and resources - a more holistic approach to storage efficiency.

DeDupe SG™ is a complete, turn-key solution with all the necessary software and hardware leveraging Nexsan’s highly efficient storage combined with FalconStor’s high performance deduplication software engine (File-interface Deduplication System - FDS). DeDupe SG represents the next generation in data deduplication by reducing capacity costs while greatly improving operational efficiency.

Save Time

• 20-100% faster than competitive vendors
• Write and store backups to high speed disk cache and dedupe later or concurrently
• Independent, high speed RAID subsystem frees CPU processing power for faster backup/restore performance
• Supports multiple streams from multipleapplications
• Symantec OST and 10Gbit sup

DeDupe SG delivers performance that is 20% to 100% faster than competitive systems wth the ability to ingest data up to 750MB/s via CIFS and NFS protocols (up to 1500MB/s with OST).

Whereas other vendors choose a path of CPU or disk to achieve speed, Nexsan has answered the obvious question - why not both? By combining the latest high speed processor technology with Nexsan’s high speed RAID subsystem, the DeDupe SG represents the next evolution in deduplication performance.

DeDupe SG is not just faster deduplication, it’s smarter deduplication. By first writing and storing backups on its high speed disk cache (deduping at a later time or concurrently), DeDupe SG reduces the amount of time needed to backup.

Unlike other dedupe systems, DeDupe SG has its own independent, high performance RAID subsystem which can scale up to 8GB cache and up to 8 RAID engines. With RAID tasks off-loaded to the subsystem, CPU processing power can be solely dedicated to deduplication allowing users to backup and restore faster.

Moreover, DeDupe SG:

• supports multiple streams from multiple applications
• delivers industry leading restore performance for fast retrieval of files to their native format
• offers an optional “hot” standby DeDupe SG appliance for high availability

Save Energy

• AutoMAID™ technology delivers speed with green by spinning down DeDupe SG storage between backups while delivering near instantaneous access to data when required
• Reduce energy costs as much as 95% when compared against normal disk storage
• Reduce energy costs as much as 60% when compared against other dedupe solutions

Dedupe storage is primarily a backup target used only during the backup window. The typical backup window is 2-8 hours a day, yet all other dedupe solutions spin disks at full speed for the remaining 16-22 hours.

Would you leave your car running at full speed in the driveway when not using it? Probably not. So why would you keep your storage running at full speed between backup windows? Not only is it wasting power to operate but wasting power to cool.

By leveraging the green efficiencies inherent to Nexsan storage components and energy saving AutoMAID™ technology, DeDupe SG users not only get better performance during their backups, they save energy and reduce costs every hour the system is idle.

AutoMAID operates transpaently in the background and self-optimizes energy efficiency by looking for opportunities to save energy. By uniquely delivering speed with green, DeDupe SG will gradually slow down and ultimately turn off its drives to conserve power while providing near-instantaneous access to data when needed.

What this means to users is that DeDupe SG can reduce energy costs as much as 95% when compared to normal disk storage and 60% when compared to other dedupe solutions.

Replication with Global Deduplication
DeDupe SG’s integrated, data replication services create an environment where data and sites are protected against loss. DeDupe SG can replicate all or some of your deduped data to another DeDupe SG system located across any LAN, MAN or WAN. DeDupe SG small office systems can also be installed at remote sites where they will dedupe and store data locally then replicate to a central DeDupe SG system for added protection.
