6.4.3 DSF local storage provider

The DSF local storage provider provides DSF local storage and interfaces to use it. A DSF local storage
provider's activity includes:
– provide DSF local storage.

7 Cloud computing based data storage federation system context
This clause describes how cloud computing can support the three main roles of the DSF ecosystem: DSF
service customer, DSF service provider and DSF local storage provider.
By using cloud computing roles, sub-roles and activities, cloud computing based DSF supports more
extensible features by facilitating on-premises storage resources which connect personal and enterprise
storage resources.
The cloud computing based DSF context is defined with new sub-roles and activities based on cloud
computing reference architecture (CCRA) [ITU-T Y.3502]. For cloud computing based DSF, CSP:storage
federation provider (CSP:SFP) for federation of DSF local storage and CSP:data manipulation provider
(CSP:DMP) for management of DSF data and policies are defined to utilize DSF local storage as shown in
Table 7-1.

Table 7-1 – Mapping roles and sub-roles between data storage federation ecosystem and
cloud computing based DSF system context

Roles and sub-roles of Sub-roles of cloud computing based data storage
data storage federation ecosystem federation system context
DSF service customer CSC: cloud service user (CSC:CSU)
DSF service provider : storage federation provider, CSP: storage federation provider (CSP:SFP),
DSF service provider : data manipulation provider CSP: data manipulation provider (CSP:DMP)
DSF local storage provider CSP: cloud service manager (CSP:CSM)

Figure 7-1 illustrates the cloud computing sub-roles related to DSF. This figure also identifies activities specific
for DSF and assigns them to cloud computing sub-roles and illustrates how cloud computing supports DSF
service from the perspective of CSP:SFP and CSP:DMP. The cloud computing based DSF utilizes other sub-
roles of CSP.
