Rockchip RK3399 and RK3328 are typically used in Chromebooks, single board computers, TV boxes, and all sort of AIoT devices, but if you ever wanted to create a cluster based on those processor, Firefly Cluster Server R2 leverages the company’s RK3399, RK3328, or even RK1808 NPU SoM to bring 72 modules to a 2U rack cluster server enclosure, for a total of up to 432 Arm Cortex-A72/A53 cores, 288 GB RAM, and two 3.5-inch hard drives.

Firefly says the cluster can run Android, Ubuntu, or some other Linux distributions. Typical use cases include “cloud phone”, virtual desktop, edge computing, cloud gaming, cloud storage, blockchain, multi-channel video decoding, app cloning, etc. When fitted with the AI accelerators, it looks similar to Solidrun Janux GS31 Edge AI server designed for real-time inference on multiple video streams for the monitoring of smart cities & infrastructure, intelligent enterprise/industrial video surveillance, object detection, recognition & classification, smart visual analysis, and more. There’s no Wiki for Cluster Server R2 just yet, but you may find some relevant information on the Wiki for an earlier generation of the cluster server.
There’s no price for Cluster Server R2, but for reference, Firefly Cluster Server R1 is currently sold for $2000 with eleven Core-3399-JD4 module equipped with 4GB RAM and 32GB eMMC flash storage, so a complete NPU less Cluster Server R2 system might cost around $8,000 to $10,000.
