System Requirements

Basic Server Specifications

Since the digital repository was written in C# predominantly, it only operates under a Microsoft Windows / IIS environment to date. However, this quick scan for issues which would preclude the software running under the Mono project is encouraging.

None of the hardware for this system needs to be particularly robust. Putting a good amount of memory in the Solr/Lucene and Database server is probably the best use of your money when building a system to run this digital repository.

It is recommended to have at least 4GB of memory and 80GB of disk space on the web server. If you are running the database, Solr/Lucene, and the builder on one server, as recommended, 10GB of RAM and several CPU cores is optimal. Your hard drive space needed for this is mostly dependent on how much full text you will have in your system. For seven million pages, our Solr/Lucene indexes take about 250GB of disk space.

.NET Framework Version 4.5

The builder and web application require the .NET framework version 4.5 to be installed on those machines. This is a free install from Microsoft and can be installed from the .NET Framework 4.5 Download Center.

Microsoft SQL Server with Full Text Searching

This system currently runs against a relational database loaded into Micorosft SQL. The full-text searching components of the database must also be installed.

The free version of Microsoft SQL (Express) is sufficient for smaller libraries. One of the following two versions are the most likely candidates for install:

IIS

The web application requires IIS 7, 7.5 or 8 to be installed on your web server. This is included in most Window machines.

For instructions on how to add the IIS to your machine, see the notes on installation from Microsoft.

Apache Tomcat

(Note: Apache Tomcat requires the installation of the latest Java JRE. )

The Solr/Lucene indexes are used for all full-text searching and can also be used for the general metadata searches.

Strictly speaking, this server is optional, although if you are loading any full-text for indexing/searching you will need this. If your collections are entirely made up of photographic material, museum artifacts, and/or audio-videos without transcripts, this server can be omitted.

Solr is included in the installation package, but it requires Apache Tomcat to be installed. Any recent version of Apache Tomcat should work. Windows service installers can be downloaded for both Tomcat 7 and Tomcat 6 from the Apache Tomcat Download Site.
