Meet the Solr Search Engine Requirements

Ensure that the target system complies with the installation requirements, as listed in the Service Manager 9.50 Support Matrix on the HPE Support Matrices web site (https://softwaresupport.hpe.com/group/softwaresupport/support-matrices).

HPE recommends using the following configurations for the Solr Search Engine:

RAM: Minimum of 8GB with 4GB dedicated to the JVM that hosts the Solr Search Engine.
For better performance, 16GB of RAM with 8GB dedicated to the JVM that hosts the Solr Search Engine.

Note: It is important to consider the size of the indexes when allocating RAM. Performance is greatly improved if there is enough RAM available to the OS, so that all the index files can be easily cached by the OS as disk seeks to load stored fields and other data from the KM index files, which can slow performance. With 4GB of RAM for the OS, an index of approximately 3GB in size could be cached easily. However, if that number is doubled to 8GB of RAM for the OS, a 6GB or 7GB index could be cached.
The servers should ideally have at least four processors (no less than two).
800 MHz or higher processor
400 MB of disc space designated for /tmp (UNIX) and \TEMP (Windows)
