Leaf-Spine Fabric & EVPN/VXLAN Services

Architecting scalable, automated, and resilient data center networks built for the demands of private cloud, AI, and modern applications.

Advanced Network Infrastructure and Design Services

Is Your Legacy Network a Bottleneck to Innovation?

Legacy three-tier architectures weren’t built for today’s data center demands. Designed around north-south traffic, they’re rigid, inefficient, and dependent on outdated protocols like Spanning Tree that waste link capacity and slow everything down.

Modern environments, from virtual machines to containers and AI workloads, move east-west, with traffic constantly flowing between systems. That shift exposes serious limits: congestion, poor mobility, and brittle scaling that slows innovation.

Even some early leaf-spine designs, especially Gen1 topologies or proprietary ACI implementations, can’t keep up. They lock you into static policy models, limited interoperability, and bandwidth ceilings that make 40G/10G look like dial-up in a 400/800G world. Whether you’re hitting capacity walls, struggling to scale out pods, or trying to escape closed architectures, it’s time to evolve.

If your data center network can’t adapt, it’s not just underperforming; it’s holding you back.

Our Approach to Building Modern Data Center Fabrics

Intelligent Visibility designs and implements next-generation data center networks using a proven two-layer architecture.

We build a highly scalable and resilient Layer 3 Leaf-Spine fabric as the underlay, providing a robust transport foundation.

On top, we deploy a flexible and intelligent EVPN/VXLAN overlay, enabling seamless Layer 2 connectivity, workload mobility, and multi-tenancy across the entire fabric.

Key Components

High-Performance Leaf-Spine Underlay

The foundation of our design is a robust Layer 3 routed underlay built on a Clos-based topology. Every leaf switch connects to every spine switch, creating a non-blocking fabric where all links are active. This architecture uses Equal-Cost Multipath (ECMP) routing to load balance traffic and provide predictable, low-latency performance for all east-west traffic flows. Scaling is simple and linear: add leaf switches for more server ports and spine switches for more bandwidth, without re-architecting the network.

Flexible EVPN/VXLAN Overlay

We decouple the logical network from the physical infrastructure using an EVPN/VXLAN overlay. VXLAN encapsulates Layer 2 frames into Layer 3 packets, allowing you to extend L2 segments anywhere across the data center fabric, or even between data centers. BGP EVPN serves as the modern, standards-based control plane, efficiently distributing endpoint reachability information and reducing reliance on inefficient flood-and-learn mechanisms. This enables true workload mobility, robust multi-tenancy, and simplified network management.

Integrated Automation and Orchestration

Modern fabrics are designed for automation from Day 0. We leverage the powerful APIs and automation platforms of our partners to deliver Infrastructure-as-Code (IaC) and NetDevOps capabilities. From zero-touch provisioning of new switches to automated configuration and compliance validation, we build networks that reduce manual effort, minimize human error, and accelerate service delivery.

Data Center Modernization for Private Cloud

For enterprises building a private cloud, a Leaf-Spine EVPN/VXLAN fabric provides the agile, scalable, and automated foundation required. It allows for the seamless integration of compute and storage resources, supports self-service provisioning for DevOps teams, and enables the secure multi-tenancy needed to host diverse applications and business units.

A leading software development firm partnered with us to replace its aging 3-tier network. The new Arista-powered fabric reduced network storage latency by 20% and enabled them to deploy new virtualized services in minutes instead of weeks across a global private cloud, wherever the workload needed to be located.

High-Performance Computing (HPC) & AI/ML Workloads

AI and HPC workloads demand ultra-low latency and high-bandwidth, lossless networking. A properly designed Leaf-Spine fabric eliminates network bottlenecks and provides the predictable performance necessary for data-intensive training models and parallel processing tasks, ensuring expensive GPU clusters are never waiting on the network.

Multi-Site Data Center Interconnect (DCI)

EVPN/VXLAN can be extended across multiple physical data centers, creating a single, unified network fabric. This simplifies disaster recovery strategies, enables active-active data centers, and allows for seamless mobility of virtual machines and applications between sites for load balancing or maintenance without service interruption.
