OSNEXUS QuantaStor is a software-defined storage solution based on the open-source Ceph project. QuantaStor eliminates all of the complexity of Ceph, thanks to advanced and easy-to-use management tools and the granular control over supported hardware resulting from the built-in storage grid technology. Even better, its tight collaboration with Western Digital lets OSNEXUS provide the same level of sophistication with an NVMe-oF backend based on WD OpenFlex technology. The solution is fully compatible with Ceph, eliminating any risk of lock-in, and it provides the same interfaces (block, file, and object) and services.

The product builds on the Ceph core to provide good S3 compatibility and efficient erasure coding and compression. It also uses data placement algorithms that are disk-, node-, and rack-aware for the best resiliency and availability.

Due to the outstanding control over infrastructure resources and the flexibility QuantaStor provides, you get fast provisioning and effective infrastructure utilization, which gives enterprises and service providers a composable infrastructure without the need for custom hardware or infrastructure the size of a hyperscaler. And though ease of deployment and management are the main selling points of this product, its flexibility and efficiency can also strongly impact TCO. Furthermore, thanks to NVMe-oF support, QuantaStor’s performance is better than that of other Ceph-based solutions.

Other additions made by OSNEXUS to Ceph include multi-cluster management, strong multi-tenancy capabilities, hardware integration, and remote replication. Security has also been improved and the product is certified to operate in compliance with several demanding regulations.

QuantaStor benefits from the large Ceph ecosystem for integration with Elastic and other tools for searching and event notifications, but the company itself doesn’t offer any solution that integrates these capabilities. The Ceph community is very active regarding the containerization of the entire solution and it is expected that QuantaStor will take advantage of this. A CSI plug-in for Kubernetes is available as well.

The product has a good analytics tool, the UI is easy to use with several standard dashboards already available, and the engine on the backend can be quickly customized to create additional dashboards with Grafana.
