MooseFS vs OrangeFS

MooseFS is distributed storage software that combines data held across multiple servers into one resource. It can be mounted as a POSIX filesystem, used as a block device, or accessed through the C API. Reads and writes run across multiple chunkservers, so adding servers can increase both storage capacity and bandwidth. MooseFS replicates data chunks and restores missing copies after disk or node loss. The Community edition is open source under GPLv2, with one active master and single-parity erasure coding. Personal provides the full Pro feature set for non-commercial use, free up to 20 TiB of used raw space; beyond that, the listed price is €9 as a one-time purchase for each TiB. Pro adds synchronized master failover and support for clusters spanning locations. MooseFS 5 adds cluster-wide authentication. Official packages are offered for Linux distributions, FreeBSD, Raspberry Pi OS, and macOS; macOS requires macFUSE and macOS 12 or later. The native Windows client is included with Pro.

OrangeFS is a free, open-source parallel storage system for large workloads in high-performance computing, Big Data, streaming video, genomics, and bioinformatics. Its user-level servers and clients let applications access disk storage across multiple servers in parallel. Configurable file striping and distributed metadata, including directory metadata, support this layout. OrangeFS supports Linux, macOS, Windows, APIs, and self-hosted deployment. Linux integration uses a kernel client available in the mainline kernel since version 4.6, and the documentation recommends the upstream kernel module. Other interfaces include a native Windows parallel client, FUSE for Linux and Mac, a direct Linux application interface, Java JNI, Hadoop HCFS, WebDAV, and optimized MPI-IO; S3 is also listed among the file access protocols. Security options include capability-based security and default, key-based, and certificate-based modes. LDAP mapping can associate a client certificate subject with a user ID and primary group ID. CloudyCluster offers configurable deployments through Google Cloud and AWS marketplaces. The open-source software is free; commercial and research support is available by quote.
