Chapter 6. System Requirements
The following table shows hardware requirements for CloverDX Server and CloverDX Cluster.
Table 6.1. Hardware requirements
|Hardware||Server||Cluster (each node)|
|RAM||8 GB (recommended 64 GB)||8 GB (recommended 64 GB)|
|Processors||8 logical cores [a]||8 logical cores [a] [b]|
|Disk space (installation)||1 GB||1 GB|
|Disk space (temp space)||> 25 GB [c]||> 25 GB [c]|
|Disk space (data)||> 50 GB [c]||> 50 GB [c]|
|Disk space (shared) [d]||-||> 50 GB [c]|
[a] 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.
[b] This may vary depending on total number of nodes and cores in license.
[c] Minimum value, the disk space depends on data.
[d] Disk space for shared sandboxes is required only for CloverDX Cluster.
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).
CloverDX Server supports:
Mozilla Firefox (latest)
Google Chrome (latest)
Since CloverDX 5.5, we no longer support Internet Explorer 11.
Java Virtual Machine
Eclipse Temurin JDK 11 HotSpot (formerly AdoptOpenJDK) or Oracle JDK 8, 64 bit
IBM SDK 8 (for IBM WebSphere and Open Liberty only)
OpenJDK 8 with OpenJ9, also called IBM Semeru (for Open Liberty only)
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.
Application Servers Compatibility
Table 6.2. Compatibility Matrix
|Application Server||Eclipse Temurin JDK 11||Oracle JDK 8|
|VMware tc Server Standard (4.1, Tomcat 9.0)||[a]|
|WebLogic Server 12cR2 (12.2.1)|
|JBoss EAP 7.2||[b]|
|Red Hat JBoss Web Server 5.4||[c]|
[a] Bellsoft Liberica OpenJDK Java 11 on CentOS or Ubuntu Linux
[b] JDK 11 is supported only with JBoss EAP 7.2.2 and above; previous versions do not support multi-Release JARs (e.g. Log4j 2).
[c] Red Hat OpenJDK Java 11 on Red Hat Enterprise Linux
Table 6.3. Compatibility Matrix - IBM
|Application Server||IBM SDK 8||IBM Semeru 8|
|Open Liberty 126.96.36.199|
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.
