Founded in France, where the firm retains its R & D, but based in San Francisco, Scality has designed a ring object storage architecture that relies on a peer-to-peer protocol derived from the MIT's Chord protocol for data distribution between nodes.

The Scality Ring relies on erasure and replication code mechanisms for data protection (either mechanism can be used depending on the size of the data) and embeds advanced functions of replication and geo-replication.

Early on, Scality realized that it could not be satisfied with only object-mode access (it offers its own S3-compatible API , support for the SNIA CDMI standard and support for the OpenStack Swift protocol ). The Ring can be accessed directly in block mode via a Linux Block Driver, but also via NFS, or via the OpenStack Cinder API.

In the latest version of its solution, Scality has particularly focused on the support of the S3 protocol, which it now considers the de facto standard protocol for access to the object storage system.

"With Ring 6.x, we offer a complete new S3 API. Its Authentication and Identification (IAM) model is compatible with that of AWS (...). A large part of the work has been to understand how Amazon has developed its IAM to create an authentication model compatible with Active Directory, "explains Jérôme Lecat.

For now, integration with Active Directory is limited to user identification and authentication. But an upcoming update should also provide built-in role-based management with the directory.

Another important new feature of Ring 6.x is the integration of CAS functions. The publisher has added WORM capabilities to its object storage solution to meet storage compliance requirements for archives (and in particular the US Securities and Exchange Commission's SEC Rule 17A-4 constraints).

Scality also offers a service offering to migrate from other WORM archives stored on Centera systems or NetApp storage arrays using SnapLock technology.

An S3 server in open source mode

The launch of Ring 6.0 was accompanied by the launch of Scality S3 Server , an open source implementation of Scality's S3 stack.

Deployable as a Docker container, Scality's S3 Server transforms any storage space into S3-compatible storage. The software uses the same authentication model as the Amazon AWS S3 service . This allows a developer to develop an application based on local storage as if it were interacting with Amazon AWS S3.

Scality Ring is part of the Magic Quadrant for object storage and clustered file system actors (Gartner source, October 2016) where it is cataloged among the leaders.
