Defined ? I certainly have and it’s also a rising topic of conversation in the
IT press. I was wondering, ‘is this a new phenomenon?’ A quick search
on the phrase throws up some interesting topics where ‘Software Defined’
made a significant difference to the production and maintenance process
in everyday appliances over the last 10 years.
One early example I found was Software Defined Radio (SDR) in 2001.This piece of common electronic gadgetry
was rigidly based on hardware and the use of discrete electronic components resulting in a solution that could
not easily be modified or changed to fix faults in design, or add new functions or features. This inflexibility seems
to have been the catalyst for the change, while new technology came onto the market which enabled features,
that were previously implemented in hardware, to be programmed in software. This made the new software design
flexible, portable and lower cost.
that in the past used to be delivered through hardware
are delivered by software abstracting functions away from
the storage hardware. Software Defined Storage (SDS)
is often quoted as one of the four critical elements of the
Software Defined Data Centre (SDDC) initiative. SDDC
is another emerging topic defining data centre architecture that spans compute, network, storage and security.
Software Defined Storage is not a new initiative and the evidence is clear. NetApp Data ONTAP has for many
decades virtualised storage services, delivering on the SDS goals and vision by abstracting functions such as
storage efficiency, storage management and data protection.
On June 11th 2013 NetApp launched Clustered DATA ONTAP 8.2. Clustered DATA ONTAP 8.2 remains the only
shipping storage system delivering on the promise of Software Defined Storage, and building on existing cloud and
virtualisation models. In this release customers have the capability to abstract data access and services from pooled
SAN and NAS hardware resources. Clustered Data ONTAP also offers the broadest storage hardware support in
the market, from NetApp optimised storage, third Party storage, commodity
storage, and cloud. This release also includes comprehensive integration of
open programmable API’s for workflow automation and introduces the capability
to apply Storage based Non-Disruptive Operations (NDO) and Quality of Service
(QoS) to ensure availability, efficiency, access, security, protection and
performance of data assets.
