OSNexus Integrates with Seagate Exos Corvault

OSNexus Corp. announced integration and certification of Seagate Exos CORVAULT for use with QuantaStor 6.

QuantaStor integrates with Exos CORVAULT enabling scale-up and scale-out cluster configurations deployed with 2 layers of erasure coding provided by the CORVAULT and a second layer provided by QuantaStor. QuantaStor also monitors CORVAULT systems to provide distributed management and alerting.

Exos CORVAULT is a fully configured, self-healing, DAS array which combines Seagate’s highest capacity enterprise HDDs with Seagate’s ADAPT and Autonomous Drive Regeneration (ADR) data protection and self-healing technologies. The CORVAULT system presents logical disk groups instead of physical disks to the QuantaStor software and also implements hardware-based erasure coding, which reduces the server CPU resources needed to run QuantaStor by 50% as compared with using JBODs.

QuantaStor uses the CORVAULT’s built-in VelosCT ASIC-based ADAPT erasure coding to enable faster system performance and simplified maintenance with faster drive rebuilds within each CORVAULT storage array, eliminating east/west network disk rebuild traffic resulting in less backend system pressure.

QuantaStor implements a second layer of erasure coding between CORVAULT systems, significantly increasing system data durability up to 14 9’s.

“The Seagate CORVAULT systems combined with QuantaStor has enabled us to deliver public-cloud like solutions to our customers with over 14x9s of data durability,” said Steven Umbehocker, CEO, OSNexus. “This is made possible with double-layer erasure coding (QuantaStor + CORVAULT) combined with the integration of CORVAULT management and monitoring into the QuantaStor platform.“

“As Seagate continues to grow drive capacity with advanced technology such as HAMR, it becomes increasingly important to deliver integrated solutions that reduce maintenance and operational costs,” said Erik Salo, VP of product and business marketing, Seagate. “We are excited about QuantaStor’s integration with CORVAULT as it enables IT organizations to implement scale-out and scale-up file, block and object storage solutions with additional 9s of data durability and lower operational costs.“

As compared with a JBOD implementation, QuantaStor Scale-out with Seagate Exos CORVAULT delivers: 

• 50% lower server CPU and RAM requirements
• 50% lower maintenance with ADAPT+ADR
• 10% lower OSNexus software license costs
• Increased data durability from 99.999% up to 99.999999999999%
