CSC2-N48SPK3
CSC2-N48SPK3 RISC-V Computing Server

Industry's first RVA23 Profile mass-production array server, featuring 10 built-in SpacemiT K3 compute nodes (quantity configurable). A single node delivers maximum frequency of 2.4GHz and peak computing power of 60 TOPS, capable of running 30B large models. It supports mainstream build systems such as Open Build Server and Koji, as well as compatibility testing for mainstream Linux distributions, open-source software, and AI frameworks. It also offers remote RISC-V cloud debugging functionality, features dual 10GbE ports and Gigabit Ethernet ports, expandable with up to 48 M.2 PCIe NVMe SSDs and comes with integrated BMC management system.

RISC-V Hardware Virtualization

Supports RISC-V hardware virtualization, providing CPU and memory virtualization capabilities through the RVH 1.0 extension, interrupt virtualization capabilities through the RV AIA extension, and peripheral virtualization capabilities through the RV IOMMU extension.

Security Defense Technology

Adopts complete RISC-V security architecture with M/S/U three‑level privileges, providing hardware‑level defense against Spectre and Meltdown attacks. Equipped with RISC-V PMP/ePMP and dedicated IOPMP mechanism for high‑level protection. Supports secure boot, secure storage, and signature verification, with integrated hardware encryption (AES/SHA/RSA＆SM2/SM3/SM4) for full lifecycle security management.

Software Compatibility Testing

Industry's first RVA23 Profile mass-production array server, supporting compatibility testing for mainstream Linux distributions, open-source software, and AI frameworks.

Remote RISC-V Debug Capability

Supports remote automatic flashing, remote serial debugging, remote SSH, web-based IDE, and remote desktop, providing out-of-the-box remote debugging environment.

Runs Various Software Smoothly

Smoothly run a variety of software, such as MySQL, Oracle, and Redis for databases; Nginx and Apache for web services; KVM for virtualization; Postfix for email services; and Hadoop and Spark for data analytics — remaining stable and efficient even when running multiple software programs in parallel.

BMC Management System

Equipped with intelligent BMC management system, enabling real-time monitoring, software configuration, hardware configuration, troubleshooting, anomaly alerts, system upgrades, and remote O&M. Equipped with a touchscreen display that shows real-time key operating data such as chassis temperature, power efficiency, fan speed, network IP, date and time.

Integrated Network Control

Features 4 x 10GbE SFP+ ports and 1 x MGMT (BMC management network interface), supporting BMC independent out-of-band operation and maintenance management. Built-in Layer 3 routing and switching, VLAN partitioning, and QoS traffic control functions effectively optimize network transmission efficiency and enhance overall system network security protection.

Up to 48 x M.2 PCIe NVMe SSDs

Onboard 48 M.2 PCIe interfaces supporting PCIe NVMe 2280 SSD expansion, enabling connection to a large number of high-speed storage devices, significantly improving data read/write speeds, meeting high-density storage requirements, and allowing the device to easily expand to TB-level ultra-large capacity.
Empower RISC-V Software Development

Powered by 8 x X100 64-bit RISC-V AI cores, SpacemiT K3 delivers 7x faster native compilation than x86 QEMU and offers a 15x better price-performance ratio compared to equivalent x86 systems. It natively supports mainstream build systems like Open Build Server and Koji, enabling automated compilation, packaging, and version iteration for firmware, kernels, and applications — meeting all server-side automated build and integration needs.
