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
  • Hardlinks
  • 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
