# Commvault Flex Open Solution Deployment Models

Flex Open supports the following deployment models.

## 1. Single-Node Deployment

The simplest deployment model consists of a single Flex Open node running all core Commvault services:

- MediaAgent
- Access Node
- Index Server
- Threat Analysis

Storage can be:

- Internal storage
- External storage
- S3 object storage
- Data Domain / StoreOnce
- NAS or SAN

Best for: - Remote offices - SMB environments - Departmental deployments - Smaller backup environments

## 2. Multi-Node Scale-Out Deployment

Multiple Flex Open nodes are deployed within the same backup environment. Each node can host Commvault services and provide:

- Additional capacity
- Additional throughput
- Additional recovery performance

This model is very similar to a traditional Commvault environment with multiple MediaAgents.

Best for:

- Mid-size and large enterprises
- Growing environments
- Higher ingest rates
- Larger recovery requirements

## 3. Distributed Storage Deployment

Flex Open nodes can be connected to various storage architectures depending on customer requirements:

This deployment model provides maximum flexibility because Flex Open supports:

- DAS
- NAS
- FC
- iSCSI
- S3
- Tape
- Data Domain
- StoreOnce

Unlike Flex Appliance, there are no storage vendor restrictions.

Flex Open can be deployed as a single-node solution, a multi-node scale-out architecture, or a distributed architecture using internal or external storage. The deployment model closely mirrors traditional Commvault MediaAgent architectures while providing the simplicity and security of VaultOS.
