System Requirements

Before you start installing the product, make sure the machine where VAO will be deployed meets the necessary hardware and software requirements.

System Requirements Important!

Mind the following limitations:

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

Specification	Requirement
Hardware	Hardware requirements depend on the size of the managed infrastructure. For details, see Hardware Recommendations.
OS	Only 64-bit versions of the following operating systems are supported: Microsoft Windows Server 2019 Microsoft Windows Server 2016 Microsoft Windows Server 2012 R2 Microsoft Windows Server 2012 Microsoft Windows Server 2008 R2 SP1 Note: You cannot install VAO on a machine running Microsoft Windows Server Core.
User Management	Windows domain-joined machine
SQL Server	Local or remote installations of the following versions of Microsoft SQL Server are supported: Microsoft SQL Server 2017 Microsoft SQL Server 2016 (2016 SP1 Express Edition is included in the setup) Microsoft SQL Server 2014 Microsoft SQL Server 2012 (2012 SP4 Express Edition is included in the setup) Note: It is not recommended to use the Express Edition in any production VAO deployments — it should only be used for product evaluation.
Additional Software	All components will be installed during setup. For inline Report Template editing, Microsoft Word component of SP2 for Microsoft Office 2010 or later is required.
Veeam Software	If a standalone Veeam Backup & Replication server is used for backup and replication task management, it must be version 9.5 Update 4 or version 9.5 Update 4a. However, it is recommended that you install version 9.5 Update 4a as it includes a number of important fixes related to VAO functionality. Notes: Connections to Veeam Backup & Replication servers version 10 and later are not supported. If you connect a standalone Veeam Backup & Replication server to the VAO server, it must be joined to either the same domain or a trusted domain.
Virtualization Platform	VMware vSphere 5.5, 6.0, 6.5, 6.7 Note: The VAO server must be connected to VMware vCenter Servers. Direct connections to vSphere hosts are not supported.
