An administrator can add equipment to DCImanager 6 regardless of its geographical location and data centers. Remote equipment can be grouped according to its location. To do so, you can utilize locations in the platform. 

A location is an interface that allows DCImanager 6 to manage equipment from one data center. Every location in the data center has a special server that is used as a DHCP server and storage of OS templates for all servers in the location. A server must be physical or virtual based on KVM virtualization. To distribute the load evenly, it is recommended to use separate servers for platform and location.

  • Supported OS:
    • AlmaLinux 8;
    • Ubuntu 20.04.
      The OS on the location server may not match the OS of the parent server;

      CentOS 7 OS is not supported. If CentOS 7 is installed on the server, you can migrate to a supported OS: Migrating from CentOS 7.

  • Servers-locations must have sufficient disk space for OS templates. We recommend allocating at least 100 Gb;
  • Servers-locations must have at least 8 Gb RAM;
  • Server-location and equipment in the location must be in the same L2 network segment;
  • Server with the platform must have access to servers-locations via SSH;
  • Applications using DHCP, TFTP, and HTTP must not be installed on servers-locations;
  • Firewall other than firewalld must not be used on servers-locations.
  • In the L2 segment of the location network the STP protocol should not be used.
  • Server-location must be able to download:

    • OS packages for configuring the location (e.g. docker, docker-compose, etc.);

    • docker images for location updates from the ISPsystem registry —;

    • OS images from the ISPsystem repository —;

    • ISO images from external resources.

/etc/hosts file

Make sure that the /etc/hosts file has an entry for the server in the format:

<server IP address> <server hostname>

/etc/resolv.conf file

Make sure that the /etc/resolv.conf file has entries in the format:

nameserver <IP address of the DNS server>

If the IP address of the systemd-resolved local service ( is specified as the DNS server, check that the DNS server addresses are specified in /etc/systemd/resolved.conf:

DNS=<servers list>

Port settings

For the location, the following ports are used:

  • DCImanager 6 access to location:
  •  servers access to location:

Preparing to set up a location with Ubuntu OS

To prepare to set up a location with Ubuntu OS, update the system:

  1. Connect to the location via SSH.
  2. Run the following commands:

    apt update
    apt upgrade
