Trials confirm DeltaStor de-duplication capabilities.

Sepaton : 25 September, 2007  (New Product)
Data de-duplication ratios of as much as fifty to one have been confirmed on Sepaton's DeltaStor software increasing speed and efficiency of enterprise back ups.
Sepaton has announced that a well-regarded analyst firm's product testing organisation, ESG Lab, has confirmed that its ContentAware data de-duplication and scalable grid-based architecture provides an approach for disk-based backup and recovery that is well-suited to the enterprise data centre. A recently published ESG Lab Validation Report details the benefits offered by Sepaton DeltaStor de-duplication software as a solution that reduces disk capacity by an impressive factor of up to fifty to one at outstanding performance levels.

The report illustrates the results of ESG Lab's comprehensive testing of the Sepaton solution and confirms significant improvements in all aspects of data protection, including reduced disk capacity for longer online data retention, solidly reliable restores, remarkable backup and recovery speeds, and easily quantifiable cost savings in storage resources as well as power, cooling and floor space.


ESG Lab performed hands-on evaluation and testing of S2100-ES2 enterprise VTL solution with DeltaStor software using a three node configuration. Symantec Veritas NetBackup was used to backup simulated real-world application data residing on a Fibre Channel attached disk array being shared by Windows and Linux servers. In the ESG Lab Validation Report, Brian Garrett, Technical Director of ESG Lab, validated that DeltaStor can be used to reduce disk capacity by a factor of up to fifty to one for fast and reliable restores and longer retention periods. And it does it fast. ESG Lab measured an impressive de-duplication rate of 250 MB/sec as 650 GB of data was processed in 45 minutes on a dedicated compute node within a three-node S2100 Enterprise VTL. A single managed solution supporting 7 TB to 2 PB of disk capacity can now be used to store up to 100 Petabytes of backup data on fast and reliable disk.


ESG Lab also tested a single node solution. According to Garrett, "The single node rate of 708 MB/sec observed by ESG Lab exceeded Sepaton's claims of 600 MB/sec. 708 MB/sec is an extremely impressive result given the theoretical wire-speed limit of a pair of 4 Gbps Fibre Channel interfaces."

"Backup administrators have been struggling for years to get nightly backups done before business resumes in the morning. Quicker recoveries are needed to increase user productivity and meet service level agreements," explained Garrett. "We confirmed that a Sepaton S2100 VTL solution can sustain more than 600 MB/sec of backup throughput per node and that performance scales in a linear fashion as nodes are added. Based on ESG Lab's experience testing a number of VTL solutions in recent years, this is an outstanding level of performance."

"One of the greatest qualities of data de-duplication is that its value is easy to quantify. If you can reduce the amount of capacity to store backup data by 10:1, 20:1 or greater, it's easy to calculate your savings," explained Asim Zaheer, vice president of marketing, Sepaton. "As the ESG Lab report makes clear, Sepaton delivers de-duplication rates of up to 50:1, and often times higher as the ESG report highlights, resulting in cost efficiencies that pay significant near- and long-term savings."

A disaster recovery plan is incomplete if a business hasn't considered what would happen if its backup hardware fails. ESG Lab has confirmed that backup jobs relying on the Sepaton S2100 continue without error as common hardware problems including hard drive and cable failures are introduced.

In addition, ESG Lab emphasised the ease of implementation of the Sepaton solution, and commented on the entry-level S2100-DS2 Express appliance. They confirmed that this solution can be dropped into a customer's existing environment without changes to policies and procedures and users can be performing backups in less than 30 minutes. ESG predicts the market will be hearing a lot more from Sepaton in years to come.
