StorONE vRAID 2.0 Sets Record in RAID Rebuild Performance

StorONE, Inc. has completed verification of its RAID rebuild performance capabilities proving the technology provides the fastest RAID rebuilds in the industry.

In 4Q19, the company announced vRAID 2.0, an enhanced version of its vRAID technology. The new version reduces the firm’s RAID rebuild times, the time required to bring a volume to a protected state after a media failure. The test shows, using 2.0, a 1PB storage system using 14TB drives can complete rebuilds in less than 2 hours. Competing technology takes days to achieve a similar rebuild.

Application Platform 5U84 server

The company verified its claims using Seagate Technology plc‘s Application Platform 5U84 server with 14 SSDs and 70x14TB HDDs. The firm configured the Application Platform with mid-range CPUs and 128GBs of memory. The company first filled the 14TB HDDs to more than 50% of capacity. It then created a drive failure, which triggered the rebuild process. The firm then measured the time it took to bring the impacted volumes back into a protected state. The result: a sub-2-hour rebuild.

“At StorONE, we commit to our customers that they will be able to take full advantage of storage hardware innovations and be ready to take advantage of future advances. vRAID 2.0 is just one example of how we deliver on that commitment. We enable the use of high-capacity drives without concern over slow rebuild times,” says Gal Naor, CEO and co-founder. “In addition to record setting rebuild times our vRAID 2.0 technology eliminates the need for hot spares and provides future-proofing via its ability to mix drive sizes within a RAID group.”

Slow rebuilds also impact flash volumes. Flash density is increasing, and competing vendors are now suffering from double-digit hour SSD rebuild times. The firm also verified its flash drive rebuild times; testing showed flash volumes rebuild in less than 4 minutes. By comparison, most vendors report 8+ hours of rebuild times for flash volumes. vRAID 2.0 can rebuild a volume made up of HDDs faster than most AFA vendors can rebuild a flash-based volume.

“Customers consistently tell us they’d like to take advantage of the power and floor space savings, as well as the cost per GB savings, of new high-density drives, but they are hesitant to adopt the technology because of slow rebuild time concerns.” added George Crump, CMO. “Our patented, high-performance, erasure coding delivers the rebuild times that customers need to embrace these technologies without hesitation.“

vRAID is built into the company‘s IO Orchestration algorithm powering a new storage platform that delivers better data reliability, simpler operation, and lower costs. Legacy storage solutions use separate software modules that execute data services serially. IO Orchestration, however, runs all data services simultaneously in parallel, lowering latency and extracting modern hardware’s full capabilities. The result is the lowest possible $/IO/s and $/GB without compromising data integrity or giving up enterprise features.
