Real Software Storage

Quobyte is a POSIX compatible, distributed parallel file system entirely in software.

Our Core Features

Scalable Performance

By eliminating bottlenecks and embracing the concept of massive scaleout for storage infrastructure, Quobyte scales linearly and without limit. That means you can always add more hardware to deliver better performance, lower latency, and higher throughput.

Deploy Anywhere™

Quobyte seamlessly integrates into your tech stack, whether you’re running on-prem bare metal x86 servers, on the cloud, or any hybrid configuration. Containers? Machine learning? Big data? Quobyte just works.

Unconditional Simplicity™

Quobyte makes an administrator’s life a little easier and enables you to operate like a hyperscaler. Key features include non-disruptive updates, runtime configurability, and no kernel modules.

360 Security

Protecting data at rest and in transit is never an afterthought. We implement security features for access control, authentication, end-to-end encryption, TLS and more.

Grand Unified Storage

Native storage for any platform: Linux, Windows, MacOS, S3, TensorFlow, HDFS, and more. Every file has a single namespace for easier sharing and distributed, parallel workloads.

Policy Based Data Management

Managing huge data volumes just got a little easier. Quobyte gives you full control over data placement, recoding, tiering, isolation, immutability, and expiration.

Storage Infrastructure

Quobyte is storage infrastructure for the scale-out generation. We include built-in multitenancy, agility, analytics, monitoring, and hardware management. Plus, everything can be controlled through the API.

End-to-end Data Protection

Quobyte protects data and metadata from corruptions caused by random bit flips by implementing end-to-end checksums on all blocks, metadata, and RPCs. We also guarantee redundancy and protect against hardware failure by using technologies like replication and erasure coding.

Native S3

Include comprehensive object storage in your overall storage infrastructure with Quobyte’s native S3. Advantages include a shared namespace for files and objects, unified access controls, and scale-out performance.
