Significantly increasing the distance between computing and storage devices, KIOXIA demonstrates optical interface broadband solid-state drive prototype

According to news from this site on August 9, according to an announcement by Kioxia on August 7, the company demonstrated a broadband solid-state drive prototype with an optical interface at the FMS 2024 Summit.

Kiaoxia said that replacing electrical wiring interfaces with optical interfaces can significantly increase the physical distance between computing devices and storage devices without affecting performance and availability. Kioxia can currently achieve optical connections of 40 meters, and will expand to more than 100 meters in the future.

AI large model training, cloud computing, etc. have put forward higher performance requirements for servers, and the power consumption and heat generation of computing devices such as CPUs and GPUs have increased significantly. Installing SSDs locally on the host will not only increase the overall heat dissipation burden, but high temperatures are also detrimental to the life of NAND flash memory.

If the storage device is placed in a separate space some distance away from the computing device, it will not only simplify the heat dissipation design, but also improve the durability of the solid state drive.

Not only that, the use of optical switches can achieve efficient aggregation and seamless interconnection of computing and storage devices, thereby further promoting the development of "disaggregated computing systems" and improving resource utilization efficiency.

This website noticed that using a smaller and more compact optical interface in solid-state drives can also simplify wiring, improve signal integrity, and enable high-performance computing in harsh environments such as high-radiation outer space.
