 as encryption, zoning, and Logical Unit number LUN masking are helpful in providing the security of data. Object based storage access can help to implement security at the object level security. Massive Scale-Out Architecture: Big data analytics is a growing field and it also a key driver for SDS. SDS provides rapid deployment of large storage capacity SO it is really helpful in operating big data and analytics over there.

It needs to provide the storage as cloud storage to its user. Auto provisioning and chargeback models is helpful in that Role of Metadata in SDS In traditional storage system the meta data generally contains information related data storage properties such as file index, file properties, file types and storage requirements but in the case of SDS meta data will serve other purposes such as to describe user requirements, define service level capabilities and control the data services. ARCHITECTURE OF SDS Data Access Protocols Study of data access protocols are most needed since any storage architecture needs to know the data is accessed in a storage system. The SDS has introduced new way to access data called object based access along with traditional block and file based I/O (Coyne L. et. al (2017)). Figure 3.

Block I/O: Block refers to block of common storage devices such as hard
