The document outlines the growing importance of software-defined storage (SDS) in IT budgets, highlighting storage as a major expenditure in large infrastructure projects. It discusses the shift from proprietary hardware to standardized, open platforms for greater agility, efficiency, and cost savings in storage solutions. Additionally, it predicts that by 2020, a significant percentage of unstructured data will be managed by SDS, indicating its critical role in future storage infrastructure.
Why Software-Defined Storage Matters
- 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.

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.
