TOKYO -- Kioxia Corporation, a world leader in memory solutions, showcased a prototype of broadband SSD with an optical interface for next-generation data centers at the “FMS: the Future of Memory and Storage” conference, being held in Santa Clara, CA from August 6 to August 8. By replacing the electrical wiring interface with optical, this SSD technology significantly increases the physical distance between the compute and storage devices, slims down wiring, while maintaining energy efficiency and high signal quality. It also brings high flexibility to data center system design and applications.

By adopting an optical interface, it becomes possible to aggregate individual components that make up systems, such as SSDs and CPUs, and seamlessly interconnect them. This furthers the evolution of a “disaggregated computing system” that can efficiently utilize resources according to a specific workload. Additionally, with its high signal integrity, the optical interface may enhance high-performance compute environments, such as outer space.

This accomplishment is the result of the Japanese “Next Generation Green Data Center Technology Development” project, JPNP21029, subsidized by the New Energy and Industrial Technology Development Organization (NEDO), which is under the “Green Innovation Fund Project: Construction of Next Generation Digital Infrastructure.” In this grant project, next generation technologies are being developed with the goal of achieving more than 40% energy savings compared to current data centers. As a part of this project, Kioxia is developing broadband SSDs with optical interface for data storage in next-generation green data centers.
