+### Technical Preview of PMM in high availability (HA) mode
+
+!!! caution alert alert-warning "Important"
+    Disclaimer: This feature has been added in PMM 2.41.0 and is currently in [Technical Preview](https://docs.percona.com/percona-monitoring-and-management/details/glossary.html#technical-preview). Early adopters are advised to use this feature for testing purposes only as it is subject to change.
+
+  Starting with this release, PMM can now be run in high availability mode with several PMM server applications and independent data sources.
+
+  Currently, PMM servers provide high availability, but users are responsible for maintaining the high availability of the data sources used by PMM.
+
+  These data sources are:
+
+  - ClickHouse: An open-source, fast analytical database.
+  - VictoriaMetrics: A scalable, long-term storage solution for time series data.
+  - PostgreSQL: A powerful open-source relational database management system used in this setup to store PMM data like inventory, settings, and other feature-related data.
+
+  If you're looking to dive deep into this feature, see our comprehensive [documentation](https://docs.percona.com/percona-monitoring-and-management/how-to/HA.html).
