Module 1: Architecture Fundamentals

Learning Objectives

By the end of this module, you will be able to:

• Describe what VergeOS is and how its unified operating system approach differs from traditional 3-tier infrastructure and other HCI platforms
• Compare HCI and UCI deployment models and recommend the right topology for a given use case
• Explain VergeFS (vSAN) storage including tier architecture, data distribution, and redundancy mechanisms
• Describe the core fabric network and how inter-node communication, vSAN replication, and VM live migration traffic flow
• Identify VergeOS node types and cluster concepts including controller nodes, scale-out nodes, compute-only, and storage-only roles

Prerequisites

None — this is the first module in the training program. No prior VergeOS experience is required.

VMware Bridge

If you have VMware vSphere experience, you will find many familiar concepts throughout this module. We include “VMware Bridge” callouts on each page to map VergeOS components to their VMware equivalents — for example, VergeHV maps to ESXi, VergeFS (vSAN) maps to VMware vSAN, and VergeFabric maps to NSX. The key difference: VergeOS delivers all of these as a single integrated OS rather than separate licensed products.

Estimated Time

2 hours (1.5 hours reading + 0.5 hours lab)

Topics

What is VergeOS?

The unified ultraconverged operating system: VergeHV (compute), VergeFS (storage), and VergeFabric (networking) in a single platform. How it compares to VMware, Nutanix, and traditional infrastructure.

HCI vs UCI

Two deployment models for different scaling needs. Hyperconverged (HCI) scales compute and storage together; Ultra Converged (UCI) scales them independently with specialized node types.

vSAN & VergeFS Storage

Software-defined distributed storage with automatic tiering (Tier 0 metadata on NVMe through Tier 5), global deduplication, and self-healing redundancy.

Core Fabric & Networking

The private inter-node mesh that carries vSAN replication, cluster coordination, and live migration traffic. Dual-switch redundancy and jumbo frame requirements.

Clusters & Node Types

How VergeOS organizes nodes into clusters with distinct roles: controller, scale-out, compute-only, and storage-only. Scaling from 2 to 200+ nodes.

Lab: Explore the Architecture

Hands-on exploration of the VergeOS Terraform playground to trace deployment topologies, examine infrastructure-as-code patterns, and design a deployment for a customer scenario.
