WHY SOFTWARE-DEFINEDSTORAGE MATTERSRoss TurkRed Hat StorageApril 2016

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.

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.

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”

THE BALANCE

FlexibleEconomical at large scale

DurablePowerful

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.

THE ROBUSTNESS OF SOFTWARE

Software is more flexible than hardwareSoftware 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

OPERATIONAL EFFICIENCY

Standardization makes storage more convenientCustomers 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.

PERFORMANCE AT SCALE

Performance should scale up as capacity doesSoftware-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
