Red Hat's Ross Turk took the podium at the Public Sector Red Hat Storage Days on 1/20/16 and 1/21/16 to explain just why software-defined storage matters.

1. WHY SOFTWARE-DEFINED STORAGE
MATTERS

2. 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.

5. 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.

8. 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.

10. 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.
WEB CONSOLE
A browser interface designed for
managing distributed storage
API
A full API for automation and
integration with outside systems
COMMAND LINE
A robust, scriptable command-line
interface for expert operators
PROVISION INSTALL CONFIGURE TUNE MONITOR
Full lifecycle management for distributed, software-defined data services

11. UNIFIED STORAGE MANAGEMENT

12. 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 products
will also be available as software only versions”

far-reaching effects.

13. THE BALANCE
Inflexible
Expensive at large scale
Durable
Convenient
Flexible
Economical at large scale
Durable
Powerful
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.
