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').
- 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.
The user entitlement “sds-hd-user” is required to access and use SDS @ hd. This entitlement is assigned by your home institution. Heidelberg users already have this entitlement included in their 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):
- Collaborating with an SV requires the entitlement 'sds-hd-user'. This entitlement is assigned by your home institution.
- 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.
- Lastly, registration for the service and setting of a service password is completed on the bwServices page .
Register a new Speichervorhaben (SV):
- 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.
- 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.
- In the final step, the registration and setting of a service password is completed on the bwServices page.
- 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.
The data will be stored on the LSDF2 storage system, the second hardware generation of Large Scale Data Facility. The LSDF2 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.

This entitlement allows a use to apply for a new SV. As part of this SV, the applicant assumes responsibility for all data stored in this SV as well as any costs incurred as a result. There is also an obligation to submit reports on the SV on a regular basis.
Recommendation: The SV entitlement should be assigned to all state users who might require their own Speichervorhaben (data storage project).
