1. WHY SOFTWARE-DEFINED STORAGE MATTERS Ross Turk Red Hat Storage January 2016
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. 2018 TOTAL ADDRESSABLE MARKET (IN BILLIONS) $18.1 $15.2 $12.3 $10.3 $16.0 OS MIDDLEWARE EMERGIN G STORAGE MANAGEMENT

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.

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.

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” Innovation Insight: Separating Hype From Hope for Software-Defined Storage Innovation Insight: Separating Hype From Hope for Software-Defined Storage 2013 2014 2015 2016 2017 2018 2019 $1,349M $1,195 M $1,029M $859M $706M $592M SDS-P MARKET SIZE BY SEGMENT $457M Block Storage File Storage Object Storage Hyperconverged Source: IDC Software-Defined Storage is leading a shift in the global storage industry, with 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.
14. WHY BOTHER? PROPRIETARY HARDWARE HARDWARE-BASED INTELLIGENCE SCALE-UP ARCHITECTURE CLOSED DEVELOPMENT PROCESS Common, off-the-shelf hardware Lower cost, standardized supply chain Scale-out architecture Increased operational flexibility Software-based intelligence More programmability, agility, and control Open development process More flexible, well-integrated technology
