IBM Strengthens its Software Defined Storage Strategy

Software defined storage (SDS) is about abstracting storage devices (making them programmable using a common interface) so that they can be addressed by a wide variety of programs written by storage vendors, users and third parties. By making storage addressable, users can add new features and functions. But even more important, users can start to break down the boundaries that exist across proprietary storage devices. In other words, users can make their heterogeneous storage devices act homogeneously – and thus unlock vendor lock-in.

IBM’s Storwize family, with its latest revision of software (V. 7.2), is positioned as IBM‘s primary storage for software defined environments. What does this mean and how does it differ from the previous version? To answer this, we must first look at the evolution of the Storwize family as well as its predecessor, SAN Volume Controller (SVC).
