dCache DSS
dCache is a distributed storage solution. It organizes storage across computers so the combined storage can be used without the end-users being aware of precisely which computer stores their data; end-users simply see a large amount of storage. Because end-users need not know on which computer their data is stored, their data can be migrated from one computer to another without any interruption of service. This allows dCache storage computers to be taken out of service or additional machines (with additional storage) to be added without interrupting the service the end-users enjoy.
