Software-defined Storage = Virtualized Storage = vSAN?

I recently get more and more into discussions around Software-defined storage and storage virtualization. Is it the same, is it partly the same, is it something totally different? In this blog post I’ll try to shed some light on the technologies of today around these buzzwords and try to make some sense at the same time.

What we used to call virtualizing storage

Before we launched the idea of the Software-defined Datacenter (SDDC) and Software-defined Storage (SDS), we were already putting hardware between storage and hosts creating an abstraction layer between the two. Good examples of this technologies are IBM’s SVC and EMC’s VPLEX.

A good example of abstraction of storage from the underlying hardware - VPLEX in a metro configuration abstracting the underlying storage to add value of stretching a LUN across phyisical locations
