Abstract

SDS@hd (Scientific Data Storage) is a central storage service for hot large-scale scientific data that can be used by researchers from all universities in Baden-Württemberg. It offers fast and secure file system storage capabilities to individuals or groups, e.g. in the context of cooperative projects. Fast access is possible from data generating facilities like microscopes as well as from data analysis systems llke HPC systems. User authentication and authorization are implemented in terms of the federated identity management in Baden-Württemberg allowing researchers to use their existing ID of their home institution transparently for this service. Data protection requirements can be fulfilled by data encryption and secure data transfer protocols. The service is operated by the computing center of Heidelberg University.
