High Availability Installations and Upgrades

LogRhythm’s High Availability solutions are architected to meet the specific requirements of organizations that need access to critical log and event data at all times. All LogRhythm appliances are built with onboard redundancy for maximum fault tolerance, but some enterprises require an even greater level of guaranteed availability.

Starting with LogRhythm 7.8, the High Availability (HA) and Disaster Recovery (DR) software was decoupled from the SIEM software. There will no longer be a new upgrade package provided for HA/DR with every SIEM release.

The current version of HA and DR software is 10.1. The same files used to upgrade to 7.12 will be used to upgrade to 7.13.

The Web Console is supported in High Availability environments (PM/XM) where each Web Console instance is run as Active/Active. In this configuration, the Web Console indices should be configured on a non-replicated disk such as C: or T:.
