SOLR Basic Distributed Requirements (Type 2)
Hardware Requirements
Since CLAIMS Direct SOLR is a pre-configured, bundled distribution of Apache SOLR, it can be deployed on any number of nodes (individual instances). This documentation describes installation and configuration on a single node without the use of SolrCloud.
...
Currently, the delivery of a fully populated CLAIMS Direct index requires the above SOLR hardware requirements. A customized deployment with select data to index is currently not offered fully populated. With a custom configuration, hardware requirements are dependent on use case and complete indexing will need to be done at the installation site.
Software Requirements
The CLAIMS Direct SOLR installation is a self-contained package suitable for deployment on any Linux server running Java 8. The simple prerequisite tool list follows:
...
Name | Used By |
|---|---|
| java | ZooKeeper, SOLR and various support tools |
| wget | Configuration tools (bootstrap-*.sh) |
| lsof | Start/stop scripts (solrctl/zookeeperctl) |
SOLR Advanced Distribution Requirements (Type 3)
Hardware Requirements
As CLAIMS Direct SOLR is a pre-configured, bundled distribution of Apache SOLR, it can be deployed on any number of nodes (individual instances). A group of nodes function to expose a collection. Further, multiple collections could be searched across the distribution.
...
Currently, the delivery of a fully populated CLAIMS Direct index requires the above SOLR and ZooKeeper configuration (8 SOLR servers + 3 ZooKeepers). Load balancers and web servers are required only if CLAIMS Direct Web Services (CDWS) will be installed as well. A customized deployment with select data to index is currently not offered fully populated. With a custom configuration, complete indexing will need to be done at the installation site.
Software Requirements
The CLAIMS Direct SOLR installation is a self-contained package suitable for deployment on any Linux server running Java 8. The simple prerequisite tool list follows:
...
The configuration script setup.sh assumes that each node in the cluster will have the same directory structure. For example, if you download to a machine and unpack the archive into path /cdsolr, the full path to the package will be /cdsolr/alexandria-solr-v2.1.2-distribution. Each node must have the path /cdsolr available for deployment. You are free to choose any mount point or path as long as they are uniform across all nodes in the cluster and as long as the mount point or path for each SOLR node has at least 1TB of available disk space.
