Minimal DSpace Production system requirements 

  • 4 2 GB of Random Access Memory (RAM)
    • 1GB for Tomcat (e.g. "TOMCAT_OPTS=-server -Xms1024M -Xmx1024M -XX:MaxPermSize=128M -Dfile.encoding=UTF-8")
    • 1GB for Database (PostgreSQL or Oracle).
  • 20 GB of Storage

An empty installation of DSpace will effectively require less than 1GB of storage. However, the storage requirements increase when content is added to the repository and logfiles grow.

Approximate cost: around $599. (roughly verified 12/05/2012 through Dell - basic R210II rack server). 

  • (or roughly enough storage for all the files you wish to store in DSpace)

This minimal system should be able to support DSpace sites of roughly 20,000 items or less.  Though the exact number of items will depend on the amount of activity (searches, accesses, downloads, etc) within the DSpace site.

An empty installation of DSpace will effectively require less than 1GB of storage.  The storage estimates are very rough. The actual amount of storage you will need depends on the size of the files you plan to store in DSpace. Files are not compressed in any way, so at a bare minimum you need enough space to store all of your files, plus some extra space for database storage and logfiles. You also will need to be prepared to add additional storage space as you add more content to DSpace.

Approximate cost: around $599. (roughly verified 12/05/2012 through Dell - basic R210II rack server). 

Mid-range DSpace Production system

  • 4 GB of Random Access Memory (RAM)
  • 200 GB of Storage (or roughly enough storage for all the files you wish to store in DSpace)

This mid-range system may be necessary for DSpace sites which either have a larger number of items (roughly 50,000 or more) or a larger amount of activity (searches, accesses, downloads, etc) within the system.  

Again the storage estimates are very rough. The actual amount of storage you will need depends on the size of the files you plan to store in DSpace. Files are not compressed in any way, so at a bare minimum you need enough space to store all of your files, plus some extra space for database storage and logfiles. You also will need to be prepared to add additional storage space as you add more content to DSpace.

High End Recommended DSpace Production system requirements:

  • Quad Core processor
  • 8GB of Random Access Memory (RAM)
  • 73 GB 15,000 rpm network disks in RAID accessible over a gigabit connection for storing the database and indexes
  • 7,400 rpm network disks in RAID accessible over a gigabit connection for storing the data whose size can be easily expanded.

The high-end system should only be necessary for extremely large or extremely active DSpace sites. The majority of DSpace sites should not require this high end system until they experience a larger amount of growth or activity.

Approximate cost: around $2500. (roughly verified 12/04/2012 through Dell)
