Architecture Overview

This section provides information on the VAO architecture and its components, and describes the most common deployment scenarios. The main components in the VAO infrastructure are:

Veeam Availability Orchestrator Server

The VAO server is the configuration, administration and management core of the VAO infrastructure. The VAO server performs all orchestration actions. This is where orchestration plans are created, stored, tested and executed. Internally, the VAO server is comprised of the following components:

All VAO components can be deployed on a single Windows-based physical or virtual machine using the unified installer.

Important

Installation of the VAO server on a machine already running standalone versions of Veeam Backup & Replication and Veeam ONE is not supported.

Veeam Backup & Replication Servers

If you already have Veeam Backup & Replication servers present in your environment, deploy a VAO agent to each of these servers to orchestrate the recovery of protected VMs.

Note

Best practice recommends that the Veeam Backup & Replication server that runs backup and replication jobs is located in the DR site. This helps you ensure that the server will not be itself lost as part of a production site outage.

You can also use the Veeam Backup & Replication servers to create and transfer storage snapshots. For more information, see the Veeam Backup & Replication User Guide, section Snapshot Orchestration.

NetApp Storage Systems

All NetApp storage systems must be connected to the VAO server. That is, you must connect both storage virtual machines that manage volumes hosting VM disks and configuration files, and storage virtual machines that manage volumes storing replicated data.

Note

You can connect only storage virtual machines to the VAO server. Connections to NetApp clusters and nodes are not supported.

vCenter Servers

All vCenter Servers that manage protected VMs must be connected to the VAO server.

I want to report a typo

There is a misspelling right here:

 

I want to let the Veeam Documentation Team know about that.
