Software defined storage (SDS) represents a critical component of software defined infrastructure (SDI). When integrated with software designed computing and networking (SDC and SDN), SDS helps enable faster, more responsive provisioning—creating an IT platform that adapts to user and business needs in real time.
SDS represents a powerful vision that could revolutionize both storage architecture and consumption models. It abstracts storage capabilities—segregating physical and virtual storage devices, and then accesses them dynamically to provide increased agility and higher quality of service. Services are orchestrated via interoperable, programmable interfaces through the software layers that are separated into a control plane (policy and management) and data planes (infrastructure and data transport).
As part of a broader infrastructure, SDS can help provide business benefits including improved efficiencies, agility, control, and flexibility. By focusing on applications that drive business, the organization is better able to immediately maximize its competitive position. With SDS allocating storage dynamically, new IT services are quickly implemented without cumbersome configuration requirements.

Multi-disciplinary teams are critical to smooth, successful SDS adoption. They often need to implement other SDI features such as SDN within the same timeframe. By changing the traditional approach, one that favored siloed expertise, effective and coherent interaction between storage, network and compute layers becomes possible.

This approach optimizes both internal and external resources. At the management level, create an environment that supports multi-disciplinary teams. Encourage engineers to learn more about other disciplines and work more closely with practitioners of them. For vendors, consider a fully open solution that provides flexibility necessary to select the right application for each business need.
For more detail on the ODCA approach to SDS, as well as SDC and SDN adoption, please review resources on our site, including SDN Usage Model and our upcoming white paper on the subject of SDI. To visualize where software defined storage, network and compute fit into the larger picture; see our ODCA Cloud Maturity Model (CMM) for more detailed information. It provides tools to help an organization identify where to focus its cloud adoption efforts.
