Editor's note
Software-defined storage, also sometimes referred to as a storage hypervisor, is a term vendors began labeling their products with over the past year or so. The name was derived from the software-defined data center and has certainly gained popularity among storage vendors. Because vendors don't all have the same idea of what software-defined storage is, the functions of the products can vary.
Though the products may have different features, experts agree that all software-defined storage products are software that abstract storage management from the physical devices so that IT professionals have better control of storage features. Software-defined storage has been compared to storage virtualization because it can help IT pros use their storage more efficiently while not limiting them to a single storage vendor or platform.
This guide was built to help you understand what a software-defined storage product can do for your data center, even as the concept continues to evolve. Below you'll find discussions on the technology from storage experts, predictions as to where software-defined storage might be in the future, as well as specific examples of how it can be used in any given environment.
1The past and future of software-defined storage
The hype around SDS technologies caught on fast as vendors began using the term to describe their products. But does that hype mean software-defined storage is the future of the data center?

There's more to SDS than software
One reason that the software-defined storage market hasn't exploded yet is that IT professionals pay too much attention to the software aspect, and not enough to the additional benefits of SDS technology. Read Now

4Toigo on software-defined storage use
When an environment is based on storage from different vendors, managing them separately makes it difficult to achieve their fullest potential capacity and performance. Software-defined storage can help with that, and it can bring additional benefits as a result.
