Enterprise-Grade Provisioning

Quobyte is not just a file system, but host to any number of file system volumes. A composable quota mechanism limits their resource consumption. File system volumes can be assigned to tenants; these tenants form isolated compartments for file systems, users, and groups. Individual tenant administrators can be appointed to manage their respective file systems and quotas. Additional to file system-level access control, access to volumes can be also restricted to specific IP ranges or by using certificates.


Extensive Policy-Based Resource Allocation

Quobyte’s file system volumes are dynamically bound to storage resources through policies, which can control data location all the way down to the level of individual files. They enable tiering, isolation of workloads, subdivision into partitions, or taking advantage of heterogeneous hardware resources. When policies change, data placement is adapted accordingly without affecting service quality.

Policy-based Resource Allocation

Integrated Monitoring and Analytics

Quobyte’s detailed accounting, analytics, and monitoring tools provide valuable insights into the usage and dynamics of an installation. Analytics include graphs for top consumers, throughput, IOPS, file stats and creates. Built-in monitoring, alerting, and automation along with an interface to external monitoring systems make Quobyte a complete system out-of-the-box.


Built-In Hardware Management

Benefit from automatic scrubbing, detection, and repair of corrupted data, and drain a server with one click. Make your admins happy with SMART monitoring and hardware watchdogs. Our device inspector detects and initializes new devices. Quobyte’s device lifecycle management and workflows top off the list to enable lights-out operations.

Hardware Management

Open Architecture

Quobyte works out of the box with your technology stack: combine it with Kubernetes, Mesosphere, or Docker to set up a reliable storage infrastructure in no time. We’re fully OpenStack-ready with drivers for Cinder/Nova, Manila, an Amazon S3 interface, and Keystone integration. Use our API to hook Quobyte into your monitoring with our Prometheus template. Benefit from Quobyte’s perfect integration with today’s infrastructure tools.

Distributed File System

Parallel POSIX file system volumes, that can be mounted to any number of hosts and include:

  • File locking, incl. range locking and unlock-to-lock consistency
  • Shared ACLs across Linux, NFS, Windows, OS X, and S3 – incl. NFSv4 ACLs
  • Extended attributes (xattrs)
  • Automatic locking for applications that are not cluster aware
  • Metadata snapshots
  • Striping: GB/s for individual files
  • Block size configurable down to file level (512 B to 2 MB)

Unif​ied Access

Unified multi-interface access with common data, metadata, access control, ACLs, and locks:

  • Native user-land client for Windows, Linux, and macOS (automatic fault-tolerance and parallel performance).
  • Simultaneous access to the same file from all interfaces
  • NFS v3/v4
  • SMB via Windows Server or Samba
  • High-performance, stateless S3 incl. web browser-based client
  • HDFS (Hadoop Filesystem)

File, Block, and Object Workloads within a Single System

High-performance storage for block workloads (VMs and databases):

  • High-concurrency random block IO with sub-millisecond latency.
  • High random IOPS and throughput on the same file system.
  • Native Qemu integration

Service provider-grade object storage with S3 interface:

  • Extensive S3 feature coverage
  • Authentication via LDAP, Keystone, and password files
  • Stateless, scalable architecture

Master small-file workloads with ultra-low latency

100% Software for Diverse Deployment Models

  • Runs on any x86 server, dedicated or converged. All major Linux distributions supported, no kernel components required.
  • Connect storage to a public cloud (AWS, Google Cloud Platform, Microsoft Azure).
  • No RAID necessary. All redundancy is done in software, across servers. No NVRAM necessary.
  • SAS/SATA HDDs and SSDs, NVMe, SMR drives
  • Fast network (10GbE+ recommended)
  • Storage cluster or hyperconverged, can be spread across rooms or geographically separated datacenters, all in one rack or a federation of clusters.

Linear Scalability and Performance

  • Direct communication from client to storage servers enables linear scalability.
  • Throughput and IOPS scale linearly with hardware resources.
  • Single file IO can scale to entire cluster bandwidth.
  • Sub-millisecond latency
  • Any number of clients or servers (starting with 4).
  • Any number of volumes.
  • Any number of tenants.
  • GB/s on single files.

Data Safety, Redundancy, Availability, and Integrity in Software

  • No single point of failure and split-brain safe:
    • Non-disruptive updates with zero downtime. Mixed version deployments possible.
    • Automatic failover in software, no extra HA setup or cost
    • Hardware failures do not threaten data consistency
  • Redundancy in software eliminates RAID:
    • Replication: quorum-based replication for strong data consistency; the entire replication stack is split-brain safe.
    • Erasure coding: space-efficient alternative to replication for sequential writes and high-throughput workloads.
  • Asynchronous replication through volume mirroring for better disaster recovery
  • End-to-end checksums protect data and metadata in transit and at rest


  • IP-based and X.509-based access control
  • Integrated certificate management
  • Management authentication via LDAP, OpenStack Keystone or integrated user management
  • S3 authentication via LDAP, OpenStack Keystone or password files
  • Multi-tenancy on the logical and physical level
  • At-rest data encryption
  • NFSv4 ACLs
