Storage Hypervisors Vs. Software Defined Storage
The IT industry is an incubator for new technology and new buzzwords. The interest around software defined networking (SDN) has given rise to the term software defined data center (SDDC), and vendors are also now talking about software-defined storage (SDS). Software-defined storage includes such concepts as policy-driven storage provisioning and the use of virtual volumes, in which the physical hardware is separated from how it appears logically to the user.
