A (sub-)project in Coscine has a certain storage contingent, also called quota. Per (sub-)project, you can assign, manage and extend quota to the associated Resource Types. If you want to apply for storage space, please find the link to the application platform in the first table on resource types and storage space per project.
Default storage space
Resource Types and Storage space per project
|Resource Type||RDS Authorized||External users||Application Platform|
|RDS-Web||25 GB default; up to 100 GB with self service||no storage space||RDS-Web resources|
|RDS-S3||no default; up to 125TB with RDS application||no storage space||RDS-S3 resources|
|RDS-WORM||no default; up to 125TB with RDS application||no storage space||RDS-WORM resources|
|Linked Data||no limit since no storage space required||no limit since no storage space required||No application needed|
The following institutions are granted access to storage space on the RDS: RWTH Aachen University, FH Aachen, University of Duisburg-Essen, TU Dortmund, HAWs & FHs of NRW, members of NFDI. So far, only RWTH Aachen University is using the application portal (as of Sept. 2022). Please read the instructions for requesting storage space below. If you are from another institution, please contact your local IT/FDM support first.
Manage storage space
You can access the storage space management via the "Settings -> Manage Quota" option in the sidebar on the left side of the project start page (see figure below). If you want to manage the quota of a subproject, you have to switch to the project page of the respective subproject and call the option from there.
Quota Management Tool
The Quota Management Tool will now open (see figure below). In the upper level under the item "Quota Management" you can define the storage quota of the project for a specific resource type in each case. You can select the resource type whose storage quota you want to manage via the "Resource Type" drop-down list at the top right. The common Coscine resource types are available for selection. Not available for selection are, for example, externally managed resources without storage space requirements such as Linked Data. The reserved storage space always refers to one resource type, not to all resource types together.
25 GB reserved memory for the RWTH-RDS-Web resource type does not apply simultaneously to the RWTH-RDS-S3 resource type. The RWTH-RDS-S3 resource type has separate storage space and must be selected (or requested) separately.
Quota allocation to resources
In the lower level under the item "Resources" you can distribute the memory of a resource type reserved under "Quota Management" to your resources already existing in the project. To do this, you can use the sliders on the right side under "Adjust Quota". Note that the reserved memory for a resource type is shared by all resources, which means that your resources must share the memory.
With 150GB of available memory in the project, you cannot reserve 150GB to a resource X and 150GB to a resource Y. Instead, you must make a split such as 50:50 (75GB:75GB).
Requesting storage space
To request additional storage for RDS-Web, RDS-WORM or RDS-S3 resources, the following criteria must be met:
- You have created a project and, if applicable, all associated subprojects in Coscine (see Creating Projects and Subprojects)
- You know how much storage space is required for the main project (and the respective subprojects)
- You are employed at the RWTH, FH Aachen or an associated organisation of the RWTH (students and externals cannot apply for storage space, this has to be done by the employed project manager)
- You know which metadata you want to use (see Metadata and Application Profiles)
Everything applicable? If yes, you can access the respective application platforms via the following links:
- RDS-S3 resources
- RDS-Web resources
- RDS-WORM resources
We from the FDM team will perform a short review and get back to you if there are any queries. Please note that the review and allocation of storage space can take up to 2 weeks. If everything is in order, we will allocate the requested quota to your project. You will receive a confirmation email after the space is allocated.
Still something unclear? Then visit our pages on Creating Projects and Metadata and Application Profiles or send us an email.
Requesting storage space for testing
Coscine users are not allocated test storage space of RDS resources for individual projects. If you want to test the use of RDS resources, we will invite you to a specially created test project with 1 GB RDS-S3 storage space for 2 months. Requests are made via the respective support email address of the university (for RWTH via email@example.com). The following information is required:
Names and email addresses of all persons relevant for the testing.
If you need more storage space or a longer period of time for your testing, please let us know via email with appropriate justification.
The duration of the testing is 2 months from invitation to the testing project. From the title of the project you can see the date of deletion. After the expiration of the 2 months you will be removed from the project and if necessary still existing files and the associated resources deleted.
