ServiceSDS@hd – Scientific Data Storage

State service for storing scientific data


SDS @ hd is a central service for securely storing scientific data (Scientific Data Storage). The service is provided as a state service to researchers of higher education institutions of Baden-Württemberg. It is intended to be used for data that is frequently accessed ('hot data').

Target group

  • Researchers



  • The service enables you to securely store scientific data that is frequently accessed ('hot data').

Access and requirements

Due to the federated identity management system bwIDM implemented in Baden Württemberg, researchers at state higher education institutions can use this service with their institutional accounts. At Heidelberg University, this is your Uni ID.

Storage resources are managed in terms of "Speichervorhaben“ (SV) (data storage projects), which can be requested for projects or working groups, for example. Each SV will be assigned a dedicated storage area that can be accessed by all users who belong to the SV.

Registration steps according to usage scenarios

Collaborate with an existing Speichervorhaben (SV):

  1. You can gain access to an existing Speichervorhaben by using the linked application SDS @ hd-Management. You can receive the necessary access data directly from the person responsible for the SV. Organizational and technical changes for the SV can also be made with this application, such as group and role management.
  2. Lastly, registration for the service and setting of a service password is completed on the bwServices page .

Register a new Speichervorhaben (SV):

  1. Requesting a new SV requires the entitlement 'sds-hd-sv, which authorizes you to register your own SV. You may need to request this entitlement from your home institution first. Employees of Heidelberg University receive this entitlement automatically.
  2. Now you can request a Speichervorhaben (SV) by using the linked application SDS @ hd-Management. Organizational and technical changes for the SV can also be made with this application, such as group and role management.
  3. In the final step, the registration and setting of a service password is completed on the bwServices page.
  4. A contract is then drafted and sent to the applicant. Only after this contract has been signed and submitted will the new SV be created. The applicant will be informed once the SV has been created.

Technical information

The data will be stored on the LSDF storage system, the Large Scale Data Facility. The LSDF system is funded by the Ministry for Sciences, Research and Arts of Baden-Württemberg (MWK) and the German Research Foundation (DFG). It is part of Baden Württemberg's implementation concept bwDATA for data intensive services at higher education institutions in the state of Baden Württemberg.


There are charges associated with using this service. More detailed information about the cost model can be found on SDS @ hd-Management.

Frequently Asked Questions



Which bwIDM entitlements are required to access SDS@hd?


A bwIDM Entitlement is used for the SDS@hd service. The criteria for awarding the entitlement to a user are entirely up to the respective home organization.

SV Entitlement 'sds-hd-sv':
This entitlement allows a user to apply for a new SV. Within the scope of this SV, the applicant assumes responsibility for all data stored in this SV, as well as for any costs incurred as a result. Likewise, regular reports are required for this SV.

Recommendation: The SV entitlement should be assigned to state users who may require their own storage projects.
