  2. Biopharmaceutics
  3. Genomics
  4. Cryo-electron Microscopy  
  5. Satellite Imaginary/Observatory
  6. Geographical Data and Mapping  
  7. Meteorology/Climate 

  • Oil and Gas
  • Video Surveillance 
  • Media and Entertainment
  • Higher Education 
  • Telecom and Internet


LeoFS Structure

LeoFS is a full POSIX compliant storage. It comes with native clients for Linux, Windows and macOS, all kernel modules that do not require any patches, using only commodity hardware.
With LeoFS, data files are transparently distributed over multiple nodes.  By simply increase the number of servers and disks in the cluster, you can seamlessly scale the file system’s throughput and capacity to the needed level, all being aggregated in a single namespace.

LeoFS was written to break away limitations from traditional storage solutions.  It does not include concepts from legacy algorithms or other open source coding.  The file system provides high performance for all workloads including big and small files, intensive reads and writes (random or sequential) and metadata heavy.  Below is single cluster threshold.

LeoFS is software defined storage system, It doesn’t depend on specific hardware or devices, so all storage server of hyperscalers can be used to build LeoFS system. 


No Bottleneck

No controllers, gateways, nor distributors is required in  LeoFS system and data files are transparently distributed over multiple nodes. All client applications communicate directly with all storage nodes.
Customer on-site 7.5PB LeoFS system, consists of 102 nodes of 4U 24-bay storage servers, with totally 1,880 drives of 4TB SATA HDDs. Dual 10GbE network is used and provides an aggregated I/O close to 150GB/s. Average single drive write 75MB/s.

Enterprise Features

  • Load balance switch, hardware evenly share system workload
  • Runs on platforms such as x86, OpenPOWER, ARM, and Xeon Phi 
  • Provides access interfaces like Samba, NFS, FTP, HTTP, iSCSI, S3 etc. 
  • Support for group/user ACLs and quota
  • Fully active network with automatic failure detection
  • Supports Infiniband, GigE, multiple subnet and bonding
  • Cold data sanity check, automatic repair, no downtime
  • WORM directory, avoid modification of saved data

LeoFS can be built with almost all storage servers on Hyperscalers website. For interested on high density storage, you can just chose those with as many disk slots as possible. Please note that LeoFS system should be built with all hot swappable disks as online system for production often will have disk defects and disk replacements. The system must be stopped if disk defects occurred in a storage server with non-hot-swappable data disks or metadata disks.  This is something we need to avoid.  In addition, no JBOD is recommended.
