software defined storage (SDS)

The Software Defined Data Center(SDDC) relies on the virtualization of the networks and the various network components. It includes Software Defined Networking( SDN), computer and server virtualization, and Software Defined Storage ( SDS) with storage virtualization.

The storage infrastructure is formed by the Software Defined Storage (SDS). The abstraction layer separates the hardware properties and the storage management. Storage is traded as independent resources, as are storage area networks( SAN) and direct attached storage( DAS). Storage is software scalable, and large storage capacities are formed from multiple storage systems.

A central aspect of Software Defined Storage is the administration and software-controlled storage management for the various storage media used in data centers. These range from flash memory, solid-state drives( SSD) and hard disk drives( HDD) to tape drives, and the system administrators ensure that the technical advantages of the various storage media are incorporated into the applications. The storage infrastructure can be expanded at any time.

To ensure that the providers and operators of software defined storage do not have to rely solely on proprietary solutions, the SNIA presented a draft standard for software defined storage in 2014, which deals with the attributes, differences and necessities of software defined storage.
