The Scality Ring:
erasure-coding and data availability

The industry’s only web-scale storage that supports any file and object applications, on any hardware—with zero downtime.

The Scality RING is software that turns any standard x86 servers into web-scale storage. With the RING, you can store any amount of data, of any type, with incredible efficiency and 100% reliability, guaranteed—all while reducing costs by as much as 90% over legacy systems.


Key Advantages of the RING

  • icon any application

    Any application: The only storage platform with native file and object storage

    Access, store, and manage all legacy and digital applications from one platform.

    Gain the agility you need to store petabytes of data regardless of size, volume, or type. With the RING, you can maximize your storage capabilities with the industry’s only storage platform that natively supports file, object, S3, and OpenStack applications. Speed your time to market by consolidating mixed workloads onto the same storage, even across multiple locations. And ensure rapid access to stored data regardless of application.

    Any hardware: Unlimited scaling with total hardware freedom

    Scale to exabytes for 90% lower TCO than legacy storage with no data migration or downtime.

    Scale rapidly and economically with web-scale storage that runs on any hardware. With the RING, you can scale as much and as often as you need—and with no data migration nor disruption. Grow capacity incrementally with minimal risk and pay-as-you-scale cost using standard x86 servers from HPE, Dell, Cisco, and Seagate or commodity ODMs. Make the most of hardware innovation by adopting more cost-efficient or performance-enhancing servers as they come available while maintaining continuous availability. The cumulative advantages of continuous scaling, low administrative overhead, and hardware and application versatility of the RING make it possible.

  • icon any cloud

    Any cloud: S3 or OpenStack, public or private

    Launch public or private cloud services with a proven storage foundation, with both AWS S3 and OpenStack compatible interfaces for maximum flexibility.

    The RING is proven with millions of end customers every day. Whether you are deploying email messaging as a service, storage-related services, or custom applications for images and video, Scality has the product and the experience to help you launch your service and scale to meet demand spikes with continuous uptime. Scality has supported both custom and packaged applications in production for years under the most demanding conditions. And the same infrastructure you use for public services can also be used for private cloud services, giving you even better economies of scale.

  • Always on

    Continuous availability

    Run your digital business with confidence, knowing your stored data is always on and always available.

    The RING enables 100% data availability and zero downtime. Support your most rigorous SLAs with reliability guaranteed under contract. The RING preserves your data through its shared-nothing, distributed architecture, which provides geographical redundancy and no single point of failure. Business continuity is further assured through built-in durability and disaster recovery features. Our customers have run for years without downtime through hardware failures, upgrades, patches, and expansions.

    Telenet, our first customer from 2010, has had run multiple generations of applications, hardware, and the RING over five years with no downtime.

A Storage Infrastructure Built for Digital Business


It takes the right foundational tenets to create a solution that offers unprecedented storage for any application, any hardware, with continuous availability. Here are ours:

  • Software-defined
  • Shared-nothing, distributed architecture
  • Multi-protocol access layer
  • Scale-out file system
  • Peer-to-peer routing and object storage
  • Policy-based data protection and self-healing
  • Native geo-distribution

A History of Innovation

Scality has been hard at work building the best storage platform to support the monumental shifts occurring in applications, architectures, and deployment models. Take a look at multiple generations of the RING:
