Software defined not that well defined….

Chaos!

“To help clarify the market

and reduce confusion, IDC

has put a stake in the ground

by clearly defining

software-based storage and

developing the industry's first

comprehensive taxonomy

supporting this definition. “

IDC Press Release, April 15, 2013

“IDC Brings Clarity to Software-Based/Software-Defined Storage Markets” http://www.idc.com/getdoc.jsp?containerId=prUS24068713

Technical Overview of Data Center Networks

Next CIO must talk about

Definition chaos was also seen with after all the

recent industry trends & ‘hypes’, like Cloud,

Convergence, VDI, BYOD, Big Data, etc.,

So it is very likely Software defined Storage (SdS)

has all the potential to become the next CIO agenda

topic again!

It is related to Software defined Networking and

Software defined Datacenter

There is a need for:

•Understanding - education

•Business benefits - value proposition

•Seeing opportunities - positioning

What if?

• We could control the Data Explosion?

• We could lower CapEx dramatically through true

Storage innovation?

• We improve Storage management finally?

Single pane of glass

Reduce the number of protocols

Having a consistent methodology in managing the datacenter

Turning Arrays to App’s

Your future Storage Array could be an app

You will download it from a store

It gives you ‘on-demand’ storage

You can leverage existing and standard

Servers and Storage (JBOD) systems

Data Management will be done by

managing a Virtual Array

Think big, understand the big picture

and see the benefits for

The challenge to get to Storage Apps

Humans prefer one to one relationship….

Improves understanding:

•Easy to learn

•Easy to manage

•Easy to make progress

(step-by-step)

That’s how IT was engineered

in the past as well
