Why Software-Defined Storage Matters
- 1. WHY SOFTWARE-DEFINED STORAGE MATTERS Ross Turk Red Hat Storage April 2016
- 2. DATA CHALLENGES Exponential growth in digital content increases pressure on capacity, scalability, and cost. The need for access to data from anywhere, anytime, on any device requires unprecedented agility. Modern services require the flexibility to store data on- premises or in the cloud. Growing content requires advanced data protection that ensures integrity & high availability at very large scale. 1 2 3 4

- 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

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.
- 12. 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.
- 13. THE ROBUSTNESS OF SOFTWARE Software is more flexible than hardware Software can do things hardware appliances can’t. SDS brings the flexibility of software to the enterprise storage world. • Can be deployed on bare metal, inside containers, inside VMs, or in the public cloud. • Can deploy on a single server, or thousands, and can be upgraded and reconfigured on the fly. • Grows and shrinks programmatically to meet changing demands
- 14. OPERATIONAL EFFICIENCY Standardization makes storage more convenient Customers can build clusters using standard hardware from existing vendors that’s perfect for their workload. • Clusters can be performance-optimized, capacity-optimized, or throughput-optimized. • Need capacity? Add more disks. Too slow? Add more servers. • Clusters can become larger or smaller with no downtime.
- 15. PERFORMANCE AT SCALE Performance should scale up as capacity does Software-defined storage intelligently uses hardware to provide performance at very large scale. • Traditional appliances perform better when they are empty than they do when they are full of disks. • Performance in software-defined storage clusters improves as clusters get larger, not the other way around. • Intel, SanDisk, Fujitsu, and Mellanox regularly contribute performance optimizations
