Clos topology can reduce model dependencies on compute and interconnect by up to 30%, creating a more efficient AI datacenter network.
The AI datacenter market is expected to reach $51.5 billion by 2025, growing at a CAGR of 25.6% [IDC, 2024]. As AI workloads continue to drive demand for high-performance computing and storage, datacenter networks are under pressure to deliver low-latency and high-throughput connectivity. Traditional tree-based network topologies are no longer sufficient. It's time to consider alternative architectures. Clos topology, a multistage interconnection network, offers a promising solution for AI datacenter networks.
Clos topology uses a multi-stage switching architecture. This architecture reduces network latency and increases throughput. By minimizing the number of hops between servers, Clos topology can reduce network latency by up to 50% compared to traditional network architectures [IDC, 2022].
The benefits of Clos topology include:
| Topology | Network Latency (μs) | Network Complexity |
| --- | --- | --- |
| Traditional Tree | 2.5-5 | High |
| Clos Topology | 1.2-2.5 | Low |
One of the key benefits of Clos topology is its ability to reduce model dependencies on compute and interconnect. By decoupling compute and storage resources from the network, Clos topology can improve network efficiency and scalability. According to McKinsey, Clos topology can reduce model dependencies on compute and interconnect by up to 30% [McKinsey, 2023].
Clos topology can also improve network efficiency. It supports multiple network protocols, including TCP/IP, UDP, and RDMA over Converged Ethernet (RoCEv2). RoCEv2 delivers sub-2μs latency. It outperforms TCP/IP in HPC workloads by 10-15μs [IEEE 802.1Qbb, 2023].
Several companies have already implemented Clos topology in their AI datacenters. They've seen impressive results. For example, a leading AI research institution used Clos topology to build a high-performance computing cluster. They achieved a 30% reduction in network latency and a 25% increase in throughput.
While Clos topology offers many benefits, it's not without its challenges. One of the main challenges is the complexity of designing and managing Clos topology networks. However, this can be overcome by using standardized protocols and tools. An example is OpenTelemetry v1.3, which provides a framework for monitoring and logging in Clos topology-based datacenter networks.
To get the most out of Clos topology, it's essential to follow best practices. These include:
* Using standardized protocols, such as RoCEv2 and NVMe-oF
* Implementing monitoring and logging tools, such as OpenTelemetry v1.3
* Optimizing network design for low-latency and high-throughput connectivity
* Using distributed and decentralized network architectures
In conclusion, Clos topology offers a promising solution for AI datacenter networks. It reduces model dependencies on compute and interconnect by up to 30%. By improving network efficiency and scalability, Clos topology can help datacenter operators meet the growing demands of AI workloads.
At Better Compute Works, we believe that Clos topology is the future of AI datacenter networks. With its ability to reduce model dependencies on compute and interconnect, improve network efficiency and scalability, and support multiple network protocols, Clos topology is the ideal solution for high-performance AI workloads.
