In today's digital-first landscape, data centers are powering everything from cloud services to AI applications.

This explosion of data and rise of technologies like big data and machine learning are placing an immense strain on data centers. This necessitates the development of robust and high-performance data center connectivity infrastructure to handle the ever-growing demands.

“The mass adoption of generative Artificial Intelligence (AI) (a type of AI that is capable of creating new data or content, rather than simply analyzing, or processing existing data), marked by the run-away success of ChatGPT since November 2022, has sparked interest akin to the California Gold Rush,” says Schroders, a global investment firm.  “Data centers, as the critical infrastructure behind the digital economy, are set to play a key role in delivering new AI tools to consumers and businesses.”

High-performance data center connectivity will be crucial to keep pace in this modern-day Gold Rush.

“With their high-speed connectivity, redundant power supply, and advanced cooling systems, data centers offer uninterrupted network operations. This infrastructure allows organizations to handle increasing volumes of data, support real-time communication, and facilitate the smooth functioning of critical applications,” says Utilities One.

5 Key Considerations for Building a High-Performance Network

Here are five key considerations for building a high-performance network infrastructure to meet the evolving needs of modern business:

  1. Network Architecture
    Traditionally, data center networks relied on a tiered model with core switches at the center, aggregation switches connecting servers, and access switches providing end-point access. This traditional tiered network architecture struggled with scalability and limitations in East-West traffic (server-to-server communication) crucial for modern applications.
East-West Traffic Communication between servers within the data center, crucial for applications like cloud services and distributed computing.
North-South Traffic Communication between the data center and external networks (internet, WAN)


Modern data centers have shifted towards flatter architectures offering greater scalability and performance:

  • Spine-Leaf: This popular design utilizes multiple high-bandwidth spine switches interconnected in a mesh topology. Leaf switches directly connect to servers, providing high-density, low-latency connections. Benefits:
    • Scalable: Adding more leaf or spine switches is straightforward for expansion.

    • High Bandwidth & Low Latency: Direct connections between leaf and multiple spines ensure efficient data flow.

    • Redundancy: Multiple paths between servers and the network increase fault tolerance.
  • Mesh: This architecture involves direct connections between all devices, forming a web-like structure. Benefits:
    • Lowest latency: Data can travel any path between devices, minimizing delays.

    • High redundancy: Multiple paths between devices ensure fault tolerance.


  1. Network Equipment
    The selection of network equipment is critical in determining the performance and reliability of the data center network.
