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.
