Is Software-Defined Storage A Solution In Search Of A Problem?

Software-defined storage, or SDS, seems such a great idea. After all, when we are faced by a new project most of us still think in terms of how many drives to buy for it, yet the fact is that we can never know what that project will need as it evolves, so we almost always […]
