I.9 Data storage federation and management

Title The use case for data storage federation and management
Description In this scenario, it is a use case for one storage system connected to various storage types. In
the figure on this use case, no matter what type of storage the storage system has, the DSF
service customer is seen as the federated storage and DSF service customer does not care
about what storage they use. Thus, a federated storage system or appliance in this figure is
responsible for making multiple storage systems of a storage visible to a single system.
Similarly, management has a unified management interface.
Role/Sub-role DSF service customer (CSC:CSU)
DSF service provider (CSP:SFP/DMP)
DSF local storage provider (CSP:CSM)
Figure (optional)

Pre-conditions – CSC:CSU requests a data storage to DSF service provider and has own data storage.
(optional) – CSP:SFP provide storage system, appliance or device to federate the other storages
