Wow! Nimbus Data Unveils 50 Terabyte ExaDrive SSDs

Today Nimbus Data unveiled ExaDrive, a powerful software and multiprocessor solution for next-generation solid state drives. Based on a patent-pending architecture, ExaDrive enables OEMs to offer SSDs with record-breaking storage capacity, unmatched density, superior longevity, and the lowest energy consumption per terabyte. With an interface and form factor identical to HDDs, but with vastly more capacity, ExaDrive will accelerate flash adoption in the data center. Viking Technology and SMART Modular Technologies recently began shipping 50 TB and 25 TB ExaDrive-powered SSDs for cloud infrastructure, technical computing, and digital content storage.

ExaDrive’s software-defined multiprocessor architecture for SSDs delivers a game-changing leap forward in capacity, density, and energy efficiency that HDDs will never be able to recoup,” stated Thomas Isakovich, CEO and Founder of Nimbus Data. “ExaDrive broadens the appeal of flash memory to tier 2 and nearline use cases, enabling flash to become the dominant data center storage media.”

Conventional SSDs are based on a single flash controller. As flash capacity increases, this monolithic architecture does not scale, overwhelmed by error correction operations and the sheer amount of flash that must be managed. In contrast, ExaDrive is based on a distributed multiprocessor architecture. Inside an ExaDrive-powered SSD, multiple ultra-low power ASICs exclusively handle error correction, while an intelligent flash processor provides wear-leveling and capacity management in software. ExaDrive’s software-defined architecture will enable SSDs as large as 500 TB by the year 2020, achieving up to 600 petabytes in a single rack. This represents a 50x increase over what is possible with HDDs today.

According to Nimbus Data, 40 million nearline/high-capacity HDDs are shipped per year, and nearly all of them use the 3.5” form factor. HDD capacity, however, has plateaued, and performance per terabyte is in freefall. Migrating to flash is paramount, but existing SSDs do not match the form factor, interface, and power envelope of HDDs, forcing users to buy all-new systems. With ExaDrive, data centers can immediately rip-and-replace HDDs with flash. ExaDrive supports the standard SAS interface and is optimized to fully utilize the volume of the 3.5” form factor. As a result, ExaDrive-powered SSDs offer 5x the capacity of nearline HDDs in the same size and power budget, enabling a 5:1 reduction in rack space and power per terabyte.

For tiered storage use cases, ExaDrive-powered SSDs give users the flexibility to mix-and-match nearline HDDs and SSDs in the very same enclosure. When compared against 2.5”, U.2, M.2, or NVMe SSDs, the common 3.5” form factor and SAS interface shared between nearline HDDs and ExaDrive-powered SSDs enable data centers to standardize on one design for all tiers of storage. This standardization simplifies the daunting task of capacity planning, maximizes rack utilization, and cuts cost by reducing the number of storage and server enclosure designs. Equally as important, ExaDrive supports up to 10 years of write endurance, reducing support costs, improving quality of service, and extending return on investment.

ExaDrive is by far the largest capacity single drive that Demartek has ever tested, either HDD or SSD,” said Dennis Martin, President of Demartek. “With a standard 3.5” form factor and SAS interface, the drive was plug-and-play in our 12 Gb/s SAS JBOD and came online immediately. Our Iometer tests found that the 50 TB ExaDrive-powered SAS SSD performed in line with Nimbus Data’s claims, consuming between 14.5 and 16.5 watts under various read and write workloads and a mere 7 watts at idle.”

Earlier this year, Nimbus Data forged strategic partnerships with leading providers of flash solutions. Viking Technology, a division of Sanmina Corporation, recently announced the UHC-Silo, a 50 TB and 25 TB SAS SSD powered by ExaDrive technology. SMART Modular Technologies, a division of SMART Global Holdings, Inc., recently announced the Osmium Drive, available in 50 TB and 25 TB capacities, also powered by ExaDrive technology.

For new design partners, Nimbus Data has developed several ExaDrive reference designs. These turn-key designs help OEMs accelerate time-to-market.

ExaDrive-powered SSDs are now generally available from our partners Viking Technology and SMART Modular Technologies.
