The following Installation and Sizing Guidelines are intended to support you with setting up the UMS environment - UMS Server, UMS Console & UMS Web App, Database, and, if required,  load balancer and ICG instances.  

The size and structure of the UMS setup depend mainly on the following criteria: 

  • Number of devices 
  • High Availablity 
  • ICG connection for devices outside of your company network  

General Preconditions  

The Installation and Sizing Guidelines apply for a standard UMS setup and describe the most common UMS environments. Any individual exceptions or requirements may not be covered by these scenarios.  

  • System requirements: UMS 6.05 and ICG 2.02 and newer  
  • UMS components (UMS Server, UMS Load Balancer, UMS Console, and database) are located in the same internal LAN (no NAT, no proxies). If there is a firewall, it must be configured according to UMS Communication Ports.
  • Devices are in the same internal LAN as UMS components (no NAT, no proxies). If there is a firewall, it must be configured according to UMS Communication Ports.
  • Devices outside of the internal LAN are connected via ICG. 
  • Devices are not booted/rebooted frequently (once a day on average). 
  • A maximum of 10 different firmware versions is managed via UMS.  
  • UMS backups and exports are not permanently stored on the UMS server host. 
  • In the case of automatic device registration (see Registering Devices Automatically): The DNS alias igelrmserver or the DHCP tag can only point to ONE UMS installation. Therefore, the installation of several separate UMS Servers (without the High Availability Extension) in one network is not recommended.
