Traditional converged infrastructure is an information technology system that packages multiple components into a single optimized IT solution. It typically brings together blade-system servers, enterprise storage arrays, storage area networks, IP networking, virtualization, and management software into a single product. Vblock Systems are an example of traditional converged infrastructure.  Hyper-converged infrastructure is a software-defined architecture with integrated compute, software-defined storage, networking, and virtualization. It enables compute, storage, and networking functions to be decoupled from the underlying infrastructure and run on a common set of physical resources that are based on industry-standard x86 components.
