Other smaller companies then adopted the term "software-defined storage", such as [[Coraid]] (defunct since 2015) and [[Scality]] (founded in 2009) whose RING delivers petabyte-scale software-defined storage.
Based on similar concepts as [[software-defined networking]] (SDN),<ref>{{Cite web |title= Definition: software-defined storage |author= Margaret Rouse |work= SearchSDN |publisher= Tech Target <!-- reliable? --> |url= http://searchsdn.techtarget.com/definition/software-defined-storage |accessdate= November 7, 2013 }}</ref>

* Automation with policy-driven storage provisioning with [[service-level agreement]]s replacing technology details. This requires management interfaces that span traditional storage-array products, as a particular definition of separating "control plane" from "data plane", in the spirit of [[OpenFlow]]. Prior industry standardization efforts included the [[Storage Management Initiative – Specification]] (SMI-S) which began in 2000.
* Commodity hardware with storage logic abstracted into a software layer. This is also described{{by whom|date=August 2014}} as a [[clustered file system]] for [[converged storage]].
