A CPU core in this context is a logical core. Most modern processors use simultaneous multi-threading (called Hyper-Threading by Intel) and the number of logical cores is double the number of physical cores.

This may vary depending on total number of nodes and cores in license.

Minimum value, the disk space depends on data.

Disk space for shared sandboxes is required only for CloverDX Cluster.

Software Requirements

Operating System

CloverDX Server is compatible with Windows 10 and Unix-based systems, as well as with other systems supporting Java (macOS, IBM System V, etc.). We test primarily on CentOS-7 (2009).

Internet Browsers

CloverDX Server supports:

  • Mozilla Firefox (latest)

  • Google Chrome (latest)

Since CloverDX 5.5, we no longer support Internet Explorer 11.
Java Virtual Machine

CloverDX Server requires Java Development Kit (JDK) to run. CloverDX Server will run with limited functionality on Java Runtime Environment (JRE) and we strongly recommend against using JRE only.

Since CloverDX 5.2, we no longer support Oracle JDK 9. Also note that we do not support Oracle JDK 10 and OpenJDK 8, or AdoptOpenJDK 8.

Database servers

CloverDX Server requires a database to store its configuration, track job execution history and other events.

We support the following database servers. CloverDX Server will work with various versions of each database, although we only test on some versions as detailed for each database.

The evaluation version of CloverDX Server uses an embedded Apache Derby database to make the installation simpler and faster. The Derby database is supported for evaluation purposes with Tomcat 9 application container only. We do not support using the Derby database in production environment. Instead, you must choose one of the databases in the list above.
