Tier-1 Data


More and more VSC users have computational tasks that make intensive use of large datasets.


The VSC Data component enables research data to stay close to the computing infrastructure during the active phase of the data life cycle.

At the same time, it allows researchers to add rich metadata for searching and contextualization, automate workflows like data collection and quality control, and share data with colleagues.


The VSC Data component is based on the open source software iRODS. Together with the data transfer tool Globus, this service makes migrating large datasets to and from HPC infrastructure easier than ever.

Please reach out to for more information.

The adjusted Regulations for 2023 can be found in the links below.

Project access Tier-1 Data

Project application

Researchers at universities, the Flemish SOCs, and the Flemish public knowledge institutions can apply for Tier-1 data resources.

The designated way to get access to Tier-1 for research purposes is through a project application. Applicants do not have to pay a contribution to the cost of resources.
The proposal should include a realistic estimate of the resources needed in the project in your application. 

You can submit proposals continuously, but they will be gathered and evaluated and resources allocated at a number of cut-off dates.
There are 3 cut-off dates in 2023:

•    February 6, 2023
•    June 5, 2023
•    October 2, 2023

Proposals submitted since the last cut-off and before these dates are reviewed together.
The evaluation commission is responsible for the review of the applications, which have to be of outstanding quality.
The preferred language for the proposals is English.
More information and the application form for 2023 can be found in the links below.
•    Enclosure 1: The application form for 2023 (docx, 49kB)
•    Submission is done via EasyChair

If you need help filling out the application, please contact
