Arrcus and Quanta Cloud Technology Forge Strategic Partnership to Deliver AI-Optimized Rack Solutions
In a groundbreaking move set to redefine the future of artificial intelligence (AI) infrastructure, Arrcus, a leader in hyperscale networking software, and Quanta Cloud Technology (QCT), a global powerhouse in hyperscale server and switch manufacturing, have announced a strategic collaboration. Together, they are integrating Arrcus’ high-performance ArcOS network operating system with QCT’s cutting-edge switching platforms to deliver rack-level solutions optimized for AI workloads. This innovative offering will make its official debut at the 2025 Open Compute Project (OCP) Global Summit in San Jose, California, on October 13.
Networking as the Accelerant for AI
The rapid acceleration of AI technologies has placed unprecedented demands on networking infrastructure. To meet these challenges, Arrcus and QCT are combining their expertise to provide customers with a validated, software-hardware integrated solution that delivers agility, scale, and openness.
“As the AI revolution accelerates, networking has become the new accelerant,” said Shekar Ayyar, Chairman and CEO of Arrcus. “Together with Quanta, we are delivering a validated AI rack solution that combines our hyperscale-grade networking software with high-performance rack-scale QCT hardware to empower customers with agility, scale, and openness.”
At the core of this collaboration is ACE-AI, Arrcus’ intelligent networking stack specifically engineered to address the unique demands of AI workloads. ACE-AI supports both IP CLOS and Virtualized Distributed Routing (VDR) architectures, enabling flexible and scalable GPU cluster designs. By facilitating lossless Ethernet fabrics through RoCEv2, Priority Flow Control (PFC), and Explicit Congestion Notification (ECN), ACE-AI ensures high throughput and ultra-low latency across training and inference workloads. Furthermore, it provides hardware-level telemetry, offering real-time visibility into system health, buffers, and counters, while seamlessly integrating with orchestration frameworks.
Cutting-Edge Hardware Integration
As part of this partnership, Arrcus will port its ArcOS onto two of QCT’s next-generation switching platforms:
- QuantaMesh TA064-IXM: An 800G switch designed for Leaf and Spine configurations, ideal for high-bandwidth, low-latency environments.
- QuantaMesh T1048-LYB: A 1G switch tailored for Out-of-Band (OOB) management, ensuring robust control and monitoring capabilities.
This joint solution is meticulously designed to cater to a variety of AI-driven use cases, including:
- AI inferencing at the edge, where low-latency performance is critical.
- Scalable AI training clusters in private and hyperscale data centers, supporting massive computational workloads.
- Multitenant AI fabrics with deterministic segmentation and isolation, ensuring secure and efficient resource allocation.
- Advanced application and network monitoring capabilities, empowering operators with actionable insights.
A Disaggregated Approach to AI Networking
Arrcus and QCT, in collaboration with Broadcom, are leveraging Broadcom’s Tomahawk 5 Ethernet switching technology to deliver a disaggregated, high-performance, low-latency backend network essential for AI workloads. This backend network enables efficient and optimized data transfers across high-performance computing clusters, AI applications, and storage systems. For the frontend network, the solution utilizes existing merchant silicon, including Broadcom’s Tomahawk 5 and Trident silicon, to build a scalable Leaf-Spine fabric. This architecture ensures a future-proof solution capable of meeting the evolving demands of AI and high-performance computing (HPC) environments.
“Partnering with Arrcus allows QCT to deliver high-bandwidth, low-latency, scalable, and validated AI rack solutions to our mutual customers,” said Mike Yang, Executive Vice President at Quanta Computer Inc. and President of QCT. “Together, we’re equipping next-generation data centers with cutting-edge switching platforms that support open networking standards to meet the demands of the AI era.”
Broadcom, a key enabler of this collaboration, expressed strong support for the initiative. “Broadcom is proud to see our Tomahawk 5 Ethernet switching technology integrated into this joint solution from Arrcus and Quanta,” said Ram Velaga, Senior Vice President and General Manager of Broadcom’s Core Switching Group. “High-performance, low-latency, and scalable networking is critical for AI workloads, and this collaboration showcases the value of combining open, innovative software with platforms built on Broadcom merchant silicon. Together, we’re enabling the next generation of AI infrastructure with the performance and flexibility customers demand.”
Advancing Open Networking for the AI Era
Beyond the immediate integration of ArcOS and QCT’s switching platforms, Arrcus and QCT are exploring additional platform integrations and finalizing a go-to-market strategy to support customer deployments and solution validation at scale. This partnership underscores both companies’ commitment to advancing open networking principles and building the next generation of AI-ready infrastructure.
By combining Arrcus’ industry-leading networking software with QCT’s state-of-the-art hardware, the collaboration addresses the growing need for scalable, high-performance networking solutions tailored to the demands of AI workloads. As organizations increasingly rely on AI to drive innovation and efficiency, the ability to deploy reliable, high-speed networks becomes paramount.
This joint effort not only highlights the importance of hardware-software integration but also reinforces the value of open networking standards in fostering innovation. With the unveiling of their AI-optimized rack solution at the 2025 OCP Global Summit, Arrcus and QCT are poised to set a new benchmark for AI infrastructure, empowering businesses to unlock the full potential of artificial intelligence.
