It reflected the industry's hardware-centric view of storage systems, which were often described by the type of media used (e.g. tape, AFAs, JBODs, etc.).

Software-defined storage (SDS) allows IT to break free from this hardware-centric universe to a world where storage is just storage. As data becomes increasingly dynamic and the relative proportion of hot, warm, and cooler data changes over time, the temperatures/tier classifications will eventually become 'shades of gray,' negating the need to have separate primary and secondary storage systems...."
