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.

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.

These technologies look south for their storage requirements, abstract this storage and Read the rest of this entry »

Announced this year at VMworld 2012 (Watch the Monday general session from 51:26) were several cool technologies coming from VMware in the near future that focus on storage, or rather vStorage: Virtual Volumes (vVols), Virtual SAN (vSAN) and Virtual Flash (vFlash?). So what is this all about, and where is it going?

How SAN and NAS systems work today, is something that they have been doing for years: Take a bunch of disks, stripe data across Read the rest of this entry »
