Nexsan Revs Up Complete SATA-based Product Family with RAID-6 Support

Higher Level Fault Tolerance Keeps Pace with Demand for Very High Capacity Arrays

Nexsan Technologies, the leader in innovative storage solutions, today announced that its full line of Serial ATA-based storage arrays now supports RAID-6, delivering an additional layer of data protection for critical enterprise storage applications.

RAID-6 is becoming an increasingly important data reliability feature for high-capacity disk arrays in customer installations and applications with extreme data availability requirements.  Nexsans full line of cost-correct SATA-based storage arrays the SATAbeast, SATAboy and SATAblade now comes standard with RAID-6 capability. 

 The addition of RAID-6 fault tolerance is the latest example of Nexsans tradition of providing customers with cost-correct, highly-scalable and high-availability storage solutions.  The combination of SATA-II performance and the enterprise-class availability enabled with RAID-6 has the potential to reshape the enterprise storage market. Customers who have been saddled with the high cost of SCSI and Fibre Channel drives can now utilise Nexsans SATA-based products to dramatically reduce the cost of primary storage for video streaming and other high-bandwidth applications.

"The massive capacities and application availability demands of enterprise customers are having a transitional impact on the way storage arrays are architected," said Gary Watson, CTO of Nexsan.  The concept of RAID-6 is not new, but only recently has it become possible to eliminate the inherent performance penalty of RAID-6 technology through developments such as Nexsans advanced ASIC technology developed for use in its SATA RAID controllers. Applying RAID-6 to fast, high-capacity SATA disk arrays provides our customers with an optimal package of capacity, performance, data availability and affordability.

Nexsans implementation of RAID-6 has been optimised for SATA disk drives, providing protection against the failure of any two drives in a RAID set.  As drives grow from 500 gigabytes to 1 terabyte and beyond, RAID-6 also protects against the small but increasingly significant chance of encountering unrecoverable media errors during a conventional RAID-5 rebuild process.  With RAID-5, such errors result in holes in the data, which may result in errors at the application layer.  RAID-6, in contrast, provides another layer of redundancy which is available to plug any such holes.

Nexsan offers a full line of RAID-6 enabled SATA storage solutions to service a broad range of applications, including fixed content, reference data and disk-to-disk backup and replication for business continuity and disaster recovery.  Nexsans SATA products feature the massive scalability of the SATAbeast, the ultra-performance of the SATAboy and the 1U simplicity of the SATAblade. All Nexsan RAID-6 enabled SATA storage arrays are currently available.
