DCImanager software is installed on:

  • platform server — physical or virtual based on KVM, Hyper-V or VMware ESXi virtualization;
  • location server — physical or virtual, based on KVM virtualization. Read more in the article Locations. General information.

To distribute the load evenly, it is recommended to use separate servers for platform and location.

Hardware requirements

Minimal system requirements:

Platform serverLocation server
CPU2.4 GHz2.4 GHz
RAM8 Gb8 Gb
Disk space110 Gb100 Gb

Intel and AMD processors with x86_64 architecture are supported. Processors with ARM architecture are not supported.


Correct platform operation is not guaranteed if the processor does not support SSE4.2 instruction set.

If you use one server for platform and location, you will need at least 210 GB of disk space to run DCImanager.


The amount of disk space consumed depends on the amount of equipment added to DCImanager.

System requirements

Supported operating system:

  • AlmaLinux 8;
  • CentOS 7 x64;
  • Ubuntu 20.04.

For DCImanager to work correctly, install the platform on the latest stable version of the operating system.

Install the platform on a fresh installation of the operating system without third-party repositories and additional services. Do not install the software manually.

The server must have Docker software version at least 20.10.10 installed. Update the Docker version if necessary.

When creating partitions on the hard drive, allocate the maximum size for the root partition.

Network settings

Allow incoming connections to the ports:

  • 22/TCP — for SSH;
  • 80/TCP — for http;
  • 443/TCP — for https.


We do not recommend disabling the firewalld service. Disabling the service can lead to malfunctioning of the platform.


  Do not disable the NetworkManager software on the server with AlmaLinux 8. Disabling the software can lead to malfunctioning of the platform.
