In order to install an IGEL UMS High Availability network, your hardware and software must meet the following minimum requirements.Â
The installation requirements can vary depending on how large your HA environment is. For more information, see Installation and Sizing Guidelines for IGEL UMS.

For the supported operating systems, see the Supported Environment section of the release notes. | |||
The UMS Server must not be installed on a domain controller system!
Manually modifying the Java Runtime Environment on the UMS Server is not recommended.
Running additional Apache Tomcat web servers together with the UMS Server is not recommended either.
High Availability with IGEL UMS Load Balancers:Â All UMS Servers and UMS Load Balancers must reside on the same VLAN.
For High Availability (UMS HA) with IGEL UMS Load Balancers, network traffic must be allowed over UDP broadcast port 6155, and TCP traffic and UDP broadcast traffic over port 61616. For further port configuration, see IGEL UMS Communication Ports.
The network configuration on Windows Servers must have the TCP/IPv6 option enabled for UMS 12.
IGEL UMS HA installation with IGEL UMS Load Balancers is not supported in cloud environments like Azure / AWS as they do not allow broadcast traffic within their networks. The HA installation without IGEL UMS Load Balancers (as well as the Distributed UMS) is, however, supported in cloud environments as of UMS version 6.10.
