Big data - Concept and application for telecommunications 5

– Easy storage management: simplified management by using a single user interface and centralized
monitoring.
– Cost-effectiveness: reduction of storage usage costs by moving rarely used customer data to a
cheaper DSF local storage.
– Performance enhancement: improvement of data access performance by storing data to high-
speed storages such as solid state disk (SSD), main memory, etc.
– Data reliability: increased reliability by replicating the data storing to another DSF local storage.
– Storage scalability: support of on-demand storage capacity by scaling storage resources.
– Storage utilization efficiency: increased of storage capacity by combining two or more DSF local
storages to store a large sized file.
– Data security: stores secure data by splitting important files into multiple fragments and storing
them on different DSF local storages.
– Data management transparency: convenient data management for data discovery, use of data
without knowledge of data location, storage type and data format.

6.3 Configuration of logical components for data storage federation
Figure 6-3 shows the general configuration environment for logical components of DSF. The logical
components consist of customer, storage connection, data manipulation, data distribution and storage, DSF
local storage management, provision and policy management and DSF local storage including cloud and on-
premises storage.

Figure 6-3 – General configuration for DSF

Storage connection component provides:

– an interface for a single virtual volume for a customer;
– a customer access mechanism to connect a single virtual volume;
NOTE 1 – The customer access mechanism includes the different types of protocols according to the
storage type such as Internet small computer system interface (iSCSI) for block device storage,
