System Requirements

The following requirements are just for the resources that you devote to your Appliance instance, not for the entire machine running your Appliance’s host environment. For example, if you are using a system with 8GB of RAM, then you will need to devote a minimum of 4GB of that RAM to your Appliance. This leaves 4GB of RAM for any other system operations.

These requirements are for basic usage. System requirements will vary greatly depending on the size of the ontologies you work with, the number of ontologies in the system, and the number of concurrent requests that the system needs to satisfy. It can also vary depending on how the ontologies are used. For example, the search index can be RAM-intensive but parsing ontologies can be CPU-intensive. You will need to experiment with your Appliance resource settings to find what works for your scenario.

Minimum system requirements

  • 2 CPU (2 GHz)
  • 4GB RAM
  • Hard disk space: 20GB
  • 4 CPU (3 GHz)
  • 8GB RAM (or more depending on the size/number of ontologies)
  • Hard disk space: 20GB (or more depending on number/size of ontologies)

Image format and operating system details

The OntoPortal Virtual Appliance image was created using the Open Virtualization Format (OVF), which should allow the machine to be used in a variety of environments. Another image is available as an Amazon Web Services Amazon Machine Instance, allowing for rapid deployment.
