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.
There are many scenarios for a CLAIMS Direct deployment that range from indexing the entire content of CLAIMS Direct XML to the sparse indexing of certain fields and ranges of publication dates for application-specific usage. There could also be specific QoS requirements: minimum supported queries per second, average response time, etc. All of these factors play a role in planning for a CLAIMS Direct SOLR deployment. Generally speaking, a stand-alone full index with the entire content of CLAIMS Direct XML requires, at a minimum, the following:

The minimum required storage allows for a full index and approximately 1-2 years of growth. It doesn't allow space for SOLR optimization (see "Commit and Optimize Operations" in Uploading Data with Index Handlers) unless carefully planned. Please contact support@ificlaims.com for more information about optimization with minimum requirements.
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:

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.
There are many scenarios for a CLAIMS Direct deployment that range from indexing the entire content of CLAIMS Direct XML to the sparse indexing of certain fields and ranges of publication dates for application-specific usage. There could also be specific QoS requirements: minimum supported queries per second, average response time et al. All of these factors play a role in planning for a CLAIMS Direct SOLR deployment.

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.
