From XtreemFS to Quobyte

Evolving Distributed Storage

Introducing Quobyte – The next-generation distributed f​ile system for petabyte-scale storage

The former XtreemFS development team embarked upon a new project and set their minds on rattling the cage in enterprise storage. They use their extensive research in distributed file systems and hands-on experience with large-scale storage deployments to enhance the many features of the open source parallel file system to create an improved and expanded new software storage system – Quobyte.

Quobyte – A single storage system for a broad range of use cases

Whether you’re running an HPC cluster, your own OpenStack deployment, or a container infrastructure, Quobyte is the right choice.

Unified Software Storage

All in One

Handle file, block, and object storage within one unified storage system (POSIX and Windows file systems, NFS, Hadoop/Spark, Amazon S3).

Complete Software Storage System

Full-Featured Management

Check and monitor your system’s health and automate your storage workflow with our inventory management, graphical console and API.

Software Defined Storage

100% Software

Build a horizontal storage infrastructure from the server hardware of your choice and avoid vendor lock-in.


With its optimized I/O path, Quobyte delivers an excellent level of random IOPS and massive throughput.

Complete Software Storage System

Linear Scale-Out

Direct client-server communication yields limitless and flexible scale-out, increasing performance linearly.


Split-brain safety, no single point of failure, full fault tolerance, and erasure coding make your storage infrastructure more robust as you grow.

Quobyte combines 10 years of distributed systems research with hands-on experience in warehouse-scale storage.

From academic research to enterprise software storage

XtreemFS is born

In 2006 a team of talented developers and researchers set out to actively develop a distributed file system that would fit the needs in high-performance computing and for use as a storage system in general.


First public release

XtreemFS is the first fault-tolerant distributed POSIX file system. And it’s open source.


Release v1.0

Support for read-only replication with failover, data center replica maps, parallel reads and writes, and a native Windows client are added.

early 2009

Working with large-scale storage at Google

Lead architect Felix Hupfeld joined Google to work on the tape backup system for Gmail. You could say, he helped remove the “beta” from Google’s mail service. His later co-founder Björn Kolbeck joined Google two years later.

late 2009

Founding Quobyte Inc.

Getting their feet wet at Google, Björn and Felix realized, XtreemFS had what it takes to make a great automated software storage system. What it needed was focus and some refinements. Quickly securing seed funding, they set about to rewrite the parallel file system from scratch, complementing and adding to the conceptual groundwork they’d laid with XtreemFS.


Quobyte releases its scalable software storage

After about a year of intense development, Quobyte was made publicly available. Features include:

  • no single point of failure
  • full replication capabilities
  • massive increase in performance
  • full-featured management and automation tools (graphical UI, CLI, alerting, monitoring)
  • better data safety with end-to-end checksums

Quobyte becomes the foundation for business-critical enterprise workloads

Quobyte is since running in production for workloads ranging from VM infrastructures and OpenStack deployments (case study) to HPC clusters in genome sequencing, and as a storage base for container infrastructures (case study).


Major update includes erasure coding

In v1.3, Quobyte got another performance increase, features erasure coding, and improved maintenance task for even greater automation, better monitoring, and overall easier mangement – making it the most advanced distributed file system.
