Installing DDM
Overview
DDM is available packaged as an ISO file, which includes a streamlined Linux distribution which has been pre-configured for the DDM application.
It is recommended that DDM is installed on VMware ESXi® or Hyper-V by importing the ISO directly. Bare metal is also supported. Whilst customers can choose alternative type 1 hypervisors, Audinate Support may be unable to provide full coverage for customer issues outside of ESXi and Hyper-V.
As of DDM version 1.7, the ISO includes the Rocky Linux 9 distribution.
Alternatively, DDM is available as an installer script to run on your existing Rocky Linux 9 system. This installation method is recommended when hosting DDM on AWS. Please refer to the 'Dante Domain Manager Deployment Guide for AWS' (available from the Dante website) for more information.
System Requirements for the Host Machine
The system requirements for the machine on which DDM is installed vary according to the number of Dante devices DDM is required to support:

The physical host machine on which a hypervisor is installed must also meet the above specifications (with additional capacity for any other applications).
System Requirements for HA (High Availability) Installations
The Standalone and HA Only nodes should ideally be specified identically, in line with the standard DDM system requirements above. If the servers cannot be specified identically, you may encounter performance degradation in the event of a failover.
The arbiter server must be reliable, but does not replicate the DDM database, and therefore does not need to match the performance of the Standalone and HA Only nodes.
Arbiter Server Minimum Requirements:
- A CPU with a minimum of 2 cores (for VMs spec 2 CPUs)
- 4GB of RAM
- At least 20 GB hard drive space
Importing the ISO Directly into a Virtualization Platform
ISO files are supported by all major virtualization platforms. Refer to the user guide for your particular platform to find out how to import an ISO file. For more information about installing DDM in a hypervisor, see the Technical Documentation page at audinate.com.
Creating a Bootable USB Drive
Audinate recommends using a dedicated flashing tool such as balenaEtcher.
Booting from USB
Once you have created a bootable USB drive, you must instruct the target computer BIOS to boot from the USB drive.
Computer manufacturers use many different BIOS implementations – refer to the instructions for your particular computer to find out how to configure the BIOS.
