Installation Requirements for the IGEL UMS
This article lists the minimum requirements your hardware and software must meet to successfully install the components of the IGEL Universal Management Suite (UMS) environment. For details on the IGEL UMS components, see Overview of the IGEL UMS.
System Requirements
You can run the IGEL UMS with Windows and Linux 64-bit systems (x86_64).
For the supported operating systems, see the "Supported Environment" section of the Release Notes.
Only run the IGEL UMS on a server that has no other server-based, database, or web applications installed. IGEL does not support installations that have other applications installed on the server.
Standard UMS Installation Requirements
Network Topology
Ensure that only one IGEL UMS instance is located in one subnet. This is true for standard UMS installations and Distributed UMS or UMS HA installations.
Background: The UMS uses a default DNS alias (igelrmserver) for automatic device registration, and this alias can only point to one UMS instance at a time. Running multiple, unlinked UMS servers could create conflicts, particularly when devices are set up for automatic registration, as devices might not reliably connect to the intended UMS instance.
Installation Requirements
The documented installation requirements are purely for the UMS services. Please check the documentation of your host OS on details about the OS requirements.
Standard UMS means that you have a single UMS Server. You can host the UMS Server with the UMS Administrator, UMS Console, UMS Web App, and optionally, an Embedded Database hosted on the same machine. In this case, your hardware and software must meet the following minimum requirements:
At least 10 GB of RAM
At least 50 GB of free disk space
4 CPUs
Under Linux, an X11 system is required. It is required by the UMS Administrator application which can only be launched on the same machine as the UMS Server.
Do not install the UMS Server 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.
Installation Requirements of UMS Components
The UMS components on the same host as the UMS Server and UMS Administrator have the following minimum requirements:
UMS Web App
At least 2 GB of RAM
UMS Console
At least 3 GB of RAM
At least 1 GB of free disk space
Embedded Database
At least 2 GB of free disk space
Standalone UMS Console Requirements
To install a standalone UMS Console on a separate host machine, your hardware and software must meet the following minimum requirements:
At least 3 GB of RAM
At least 1 GB of free disk space
2 CPUs
Database Systems (DBMS) Requirements
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.
Browser Requirements
As of UMS 12.08.100, the login procedure to the IGEL UMS has been changed and requires now a modern browser on the system. For the supported browsers, see the “Supported Environment” section of the Release Notes.
For the login requirements, see UMS Login Requirements.
High Availability Requirements
The High Availability (HA) extension is designed to address the needs of large environments by implementing a network of several UMS Servers. For details on HA, see High Availability.
The embedded database cannot be used for a High Availability network. You can use the embedded database only for a dedicated test installation with only a single server for the UMS Server and Load Balancer.
High Availability with IGEL UMS Load Balancers: 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.
