In order to install an IGEL UMS High Availability network, your hardware and software must meet the following minimum requirements.

Installing UMS High Availability Network

UMS Server (includes UMS Server, UMS Administrator, and UMS Console)

Operating system: Microsoft Windows Server 2008 R2 or newer

UMS Server:

  • At least 4 GB of RAM
  • At least 2 GB of free HDD space

UMS Console:

  • At least 3 GB of RAM
  • At least 1 GB of free HDD space

UMS Administrator:

  • At least 1 GB of RAM

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.

When installing the UMS Server as a part of the HA network on Linux, the directory /root must be writable for the user root.


UMS Load Balancer

  • At least 1 GB of RAM
  • At least 1 GB of free HDD space

The UMS Server and UMS Load Balancer must be in the same IP network. There must be NO NAT or proxies between the UMS Server and UMS Load Balancer because they can influence communication between the components. 
If there is a firewall between the UMS Server and UMS Load Balancer, it must be configured according to UMS Communication Ports.

Database Systems (DBMS)

For details on the supported database systems, see the "Supported Environment" section of the release notes. Details of the requirements when installing and operating the database can be found in the documentation for the particular DBMS.

The embedded database cannot be used for an HA network. You can use the embedded database only for a dedicated test installation with only a single server for the UMS Server and UMS Load Balancer.

The database system must be accessible to all UMS Servers.
