The Organization

A global life sciences manufacturing organization operating legacy multi-vendor network fabrics across multiple data centers. The NADC facility required a purpose-built infrastructure supporting modern workloads while establishing operational patterns for enterprise-wide standardization.

Greenfield data center deployment requiring approximately 86 Arista switches with EVPN/VXLAN architecture, GitOps automation, and Multi-Domain Segmentation capabilities.

The Challenge

The organization's legacy multi-vendor network fabrics created operational complexity and limited scalability across their global infrastructure. The NADC data center represented an opportunity to establish modern operational patterns that could be replicated enterprise-wide.

Traditional deployment approaches would perpetuate manual configuration management and vendor-specific operational silos, preventing the standardization needed for global scale.

Legacy multi-vendor fabrics limiting operational consistency
Manual configuration management creating deployment delays
Lack of standardized automation frameworks across sites
Limited traffic visibility for security policy enforcement
Need for reusable design patterns for global deployment

IVI's Approach

IVI deployed an open standards-based EVPN/VXLAN Layer 3 Leaf-Spine architecture using Arista EOS platforms with comprehensive Infrastructure as Code methodologies and GitOps operational frameworks.

Phase 1: Architecture Design & AVD Modeling

Created comprehensive L3LS design documentation and built purpose-built Arista Validated Designs (AVD) data models for approximately 86 devices with reusable configuration templates.

Phase 2: GitOps Environment Development

Established Git repository with version control, branch protection, and Ansible playbooks for fabric provisioning. Integrated CloudVision for configuration deployment and pre-validated models using Arista CloudEOS Test.

Phase 3: CloudVision as a Service Setup

Configured CVaaS for Day 0 and Day 1 operations with Zero Touch Provisioning strategy, monitoring baselines, and telemetry collection for operational visibility.

Phase 4: Deployment & MSS Activation

Executed fabric build-out with comprehensive NRFU validation and deployed Multi-Domain Segmentation with ZTX appliances for east-west traffic monitoring and policy recommendations.

FAQs
How does GitOps automation improve data center operations?

GitOps automation eliminates manual configuration errors and provides version control for all network changes. The AVD framework ensures consistent configurations across all devices while enabling rapid deployment and rollback capabilities through CI/CD processes.

What is Multi-Domain Segmentation and why is it important?

Multi-Domain Segmentation provides comprehensive east-west traffic visibility and automated policy recommendations. It enables zero-trust security implementation by mapping application flows and suggesting appropriate segmentation policies without disrupting operations.

Can this L3LS design be replicated across other data centers?

Yes. The AVD framework and GitOps processes create reusable design patterns that can be adapted for different data center requirements while maintaining operational consistency and automation capabilities.

How long does NRFU validation take for a fabric this size?

Network Ready for Use validation is automated through Ansible test suites and typically completes within hours. The comprehensive testing covers hardware health, routing convergence, and Layer 3 connectivity across all 86 switches.
