I.4 Policy-driven provision and management of DSF local storage

Title Policy-driven provision and management of DSF local storage
Description A DSF service provider manages and provides a single virtual volume based on DSF local
storage policies. The DSF service provider organizes DSF local storage policies by using default
policies configured by DSF service provider and re-configured by DSF service provider from
multiple data storages. That is, the DSF service provider's policies are dependent on storage
provider storage policies in DSF local storage.
DSF service provider provides the default policies as multiple options (e.g., backup, replication,
snapshot, auto-scaling and storage type). DSF service customer selects options and DSF service
provider applies options onto metadata. The options are matched onto corresponding storage
policies in DSF local storage. The DSF service provider manages the DSF local storage by
matched functions onto storage policies. All communications with DSF local storage between
the DSF service provider and DSF local storage provider are performed by storage APIs.
