WHY SOFTWARE-DEFINED STORAGE MATTERSRoss TurkRed Hat StorageJanuary 2016

STORAGE IS A BIG PART OF IT BUDGETS

Storage is a top 3 spending category in any large infrastructure project, alongside

servers and networking.

Storage in the enterprise has been growing at 40%+ per year, and there is no

sign this growth trend is slowing.

A very large share of IT budgets is spent on storage solutions.

WHAT IS SOFTWARE-DEFINED STORAGE?

STORAGE VIRTUALIZATIO

Storage virtualization is the use of software and standard hardware to provide services traditionally provided by single-purpose storage appliances (similar to server virtualization, which uses software to

emulate servers), providing increased agility and efficiency.

VIRTUALIZED STORAGE SCALES BETTER

STANDARD SAN/NAS IS ON THE DECLINE

Server-based storage is “will account for over 60% of shipments long term.”

“By 2016, server-based storage solutions will lower storage hardware costs by 50% or

more.”Gartner: “IT Leaders Can Benefit From Disruptive Innovation in the Storage Industry”

Credit Suisse Storage Update, September 3, 2015

Changing workloads drive the need for flexible, economical server-based

storage.

STORAGE ORCHESTRATION

Storage orchestration is the ability to provision, grow, shrink, and decommission storage resources on-demand and programmatically,

providing increased control and integration of storage into a software-defined data center.

UNIFIED STORAGE MANAGEMENT

A RISING TIDE

“By 2020, between 70-80% of unstructured data will be held on lower-cost storage managed by SDS”

“By 2019, 70% of existing storage array productswill also be available as software only versions”

Appliances are suitable for small-scale, workloads, but they do not

scale economically.

Software-defined storage has a learning curve, but bring

performance and economy at petabyte scale.
