The Future of Enterprise Storage is Here

MooseFS distributes data in parallel over a virtually unlimited number of servers that act as one disk to the client devices accessing it. MooseFS has been used in petascale production deployments for over a decade.

Flexible Deployments

Deploy On-Premises, Geographically Distributed, Cloud, or Hybrid MooseFS Clusters without any hardware lock-in.

No Single Point of Failure

Advanced fail-over mechanisms ensure unparalleled cluster uptime and self-healing algorithms ensure data integrity.

Unbeatable Performance

Customers often see 2X to 10X performance improvements over alternative solutions.

MooseFS goes Enterprise

Back in June 2018, the leading file system company Tuxera Inc. started a close partnership with the developers of MooseFS. In less than a year, the combined offering of MooseFS by Tuxera has gained substantial traction in the market – allowing it to become an independent business.

Based on this success, Tuxera decided to spin off its MooseFS vertical into a new company Alcestor Inc. (“alces” means moose, in Latin), which focuses 100% of its efforts on the MooseFS technology and the business around it.

Alcestor is led by Tuxera’s seasoned management team along with the core team that has worked on the MooseFS technology for more than 10 years.

Alcestor’s goal is to be the #1 enterprise storage software provider for HPC, media, research, archive and cloud users who require rock-solid software that scales the data lightning fast and enables exabyte applications.

How MooseFS Works

MooseFS distributes data in parallel over a virtually unlimited number of servers that act as one disk to the client devices accessing it.

Practically 100% Uptime

The Master Servers hold multiple redundant copies of the meta-data, while Chunk Servers redundantly store the data.

Designed for Performance

All I/O operations are performed in parallel threads resulting in high read-write performance.

Scalable Architecture

Easily scale your cluster to 16 exabytes across thousands of nodes.

Pushing the Limits

MooseFS operates your hardware to its fullest, while providing more features at competitive TCO.


Efficiently use idle CPU, GPU and memory resources for low-latency data processing and storage on the same machine.

Advanced Caching Algorithms

Read-write caching at node and client level, which significantly boosts performance of HDD clusters and in scenarios when multiple clients access a file in parallel.


MooseFS is not only the fastest parallel file system on the market, but it is also full of enterprise features:

  • Erasure Coding
  • Tiered Storage
  • On-the-fly Upgrades
  • POSIX-Compliant
  • Fast Disk Recovery
  • Quotas
  • Atomic Snapshots
  • Global Trash
  • Access Controls
  • Unparalleled Admin Tools
