Moving large datasets, or volumes of data, is a challenge. In most cases, networks optimized for business operations are neither designed for, nor capable of, supporting the data movement requirements of data-intensive research. When scientists/researchers attempt to run data-intensive applications over these so-called “general purpose”/enterprise networks, the result is often poor performance – in many cases poor enough that the science mission is significantly impacted.
The Council for Scientific and Industrial Research (CSIR) through the South African National Research Network (SANReN) is piloting this new Service as an effort to increase the transfer speed and reliability of large datasets by South African researchers and scientists via SANReN.

We have since set up three Data Transfer Nodes (DTNs) in Cape Town, Johannesburg and Pretoria that are now available to the South African Research and Education community to assist in data transfer movement nationally and internationally as a pilot project on a trial basis.

If you would like to know more about this project, make use of these DTNs to transfer large datasets to and from your institution or know of a project that could benefit from utilising this service, please email

If you need access to the Data Transfer pilot service for the South African Research community, please complete the survey.
