7.1 CSP:storage federation provider (CSP:SFP)

CSP:storage federation provider (CSP:SFP) is responsible for the federation of DSF local storage. CSP:SFP's
activities include:

– provide virtual storage pool;
– provide single virtual volume;
– manage storage management metadata;
– manage data storage policy.

7.1.1 Provide virtual storage pool
This activity involves integrating and managing DSF local storage to make a logical storage.

This activity involves:
– performing storage operation (see clause 6.1);
– managing virtual storage pool;
– delegating customer credentials of DSF local storage.

7.1.2 Provide single virtual volume
This activity involves providing and processing a way to use a single virtual volume for a CSC:CSU.

This activity involves:
– managing single virtual volume;
– providing a user access mechanism for CSC:CSUs;
– performing storage operation (see clause 6.1).
