Distributed UMS vs. UMS High Availability (HA)
If you want to install the UMS with multiple servers, IGEL recommends to use the Distributed UMS feature:
-
for new installations
-
for existing single-instance installations. For more details, see IGEL UMS Installation.
If you have an existing fully functional HA installation, you can leave everything as it is. Note, however, that no new features will be added for the UMS HA.
If you want to migrate, see How to Migrate a UMS High Availability Installation to a Distributed UMS.
UMS Licenses
Starting from IGEL UMS version 12.07.100. the feature is only available with specific UMS Licenses. For details, see IGEL OS Editions.
IGEL OS Licenses
IGEL OS 11 and Higher
The IGEL UMS High Availability Extension no longer requires an additional license.
Before IGEL OS 11
The High Availability Extension comes in packages of 50 licenses. These licenses are installed in the UMS. The UMS checks if the number of licenses is at least as high as the number of devices connected to the UMS.
Each version of the IGEL UMS contains five test licenses allowing you to evaluate the function free of charge and without having to register.
→ Register the license file you receive in the UMS Console under UMS Administration > Global Configuration > Licenses > UMS Licenses.
An HA network only works with a license covering all managed devices registered in the UMS. A mixed mode (devices with HA support and devices without HA support) is not possible.
