Zephyr System Requirements

Starting October 11, 2024 (Zephyr Enterprise 8.2), the Zephyr Enterprise documentation moved from its current location on Atlassian to a dedicated, standalone Zephyr Enterprise documentation page. Please see: https://support.smartbear.com/zephyr-enterprise/docs/en/zephyr-enterprise/zephyr-installation---upgrade-guides/zephyr-system-requirements.html

Zephyr Enterprise must run in an isolated instance where no Jira or any other Tomcat is running.

Zephyr Enterprise should only be installed on its own server. If you are running a Jira instance, it should be installed on a different server.
We recommend you have Zephyr Enterprise installed on a separate instance from where you have your Jira/Tomcat installed.
RabbitMQ and ZE-Services should be installed in a separate server as we require Java 17 (optional for the Zephyr Enterprise version).

General System Requirements

Windows Servers	Linux
Windows Server 2016	Red Hat Enterprise 64-bit (the latest supported version is RHEL 8)
Windows Server 2019	CentOS 8 64-bit
	Ubuntu/Debian 64-bit
	SUSE/openSUSE 64-bit

Evaluation Environment	Production Environment
The Zephyr Enterprise installer provides an option for using Embedded MySQL for the database. This should only be used for evaluation purposes and not for production instances.	We recommend you always use an external database for improved performance and easy maintenance when setting up your production instance/server. This provides you with proper system performance for your Zephyr Enterprise instance.
