Scality: Object Storage With Full Scale-Out File System Support

With this post we are initiating coverage of Scality, a firm we are hearing quite a bit of buzz about lately.

We first heard of Scality in news of their VC funding rounds in early 2011, and soon thereafter began to get questions from government infrastructure professionals asking how Scality compares to Cleversafe. Cleversafe has been a pioneer and at the time Scality was just a fast moving new entrant. Both companies have improved their offerings since then but enterprises will need to invest due diligence to determine which is the best approach for them. For those starting due diligence it is becoming clear to me that one key evaluation of both firms needs to be how well they are serving existing users. But of course the technology and its performance are also key.

Scality's key offering is RING.  This is a petabyte-scale, software-only storage solution based on patented object storage technology built using a distributed, shared-nothing architecture with no single point-of-failure. Built-in tiering provides maximum flexibility in storage configuration, and delivers low latency and high performance.

From their website:

Scality RING provides scalability both in capacity and performance, is cost efficient to operate and delivers comprehensive data protection. Scality’s RING software storage solution operates seamlessly on any commodity server hardware, turning generic x86 servers into a reliable, high performance storage platform. The servers provide the storage media, whether it is performance oriented SSDs or capacity oriented SATA drives. Scality’s software takes care of the rest, delivering centralized management, data protection, self-healing, high availability and automated-tiering.

Scality RING supports POSIX file systems, including its own Scale-Out File System, is available with Multi-Geo support for geo-redundancy and high availability, and ARC erasure coding for efficient data protection.  The Scality Scale-Out File System is a complete, fully functional storage system. It delivers a state of the art solution for file access, sharing and distribution and provides the complete functionality that any application would expect from a file system. The Scality Scale-Out File System has a parallel design from the client to the core of the RING storage nodes, facilitates application integration, and is fully scalable.  Multi-Geo facilitates synchronous and asynchronous geo-distribution across multiple, geographically distributed, data centers, allowing users to access distributed data-centers from one central data-center, thus reducing user response times and ensuring faster disaster recovery. ARC (Advanced Resilience Configuration), Scality’s erasure coding technology, provides support for erasure coding for data protection and resilience. It is a better alternative than RAID, providing protection against simultaneous failures at the disk, server and network levels, and addressing the cost concerns associated with large-scale deployments.

Additionally, Scality’s Sync-n-Share file synching and sharing module, as well as its REST HTTP, RS2, Cinder Openstack and Hadoop CDMI APIs, are available as add-on options.
