ObjectiveFS vs OrangeFS

ObjectiveFS is a shared distributed POSIX file system for persistent storage across cloud instances, laptops, containers, and office servers. It runs on Linux and macOS and can be self-hosted. The software runs on customer machines and connects directly to object stores through the S3 API, without storage clusters or metadata servers. Multiple machines can read and write the same filesystem, with updates visible across them. Supported targets include Amazon S3, Google Cloud Storage, Azure Blob Storage, IBM Cloud Object Storage, Oracle Cloud, DigitalOcean Spaces, Scaleway, Wasabi, Ceph, MinIO, NetApp StorageGRID, Hitachi Content Platform, and S3-compatible stores. Data is encrypted locally with a customer-known key and remains encrypted in transit and at rest; checksums verify integrity. Automatic and checkpoint snapshots can be mounted read-only. Personal costs $99 a month and includes 3 instances, up to 50 instances, 5TB storage, and unlimited filesystems. A 14-day trial is available, but there is no free plan. Object-store charges are billed separately. ObjectiveFS does not run natively on Windows, though a Linux machine can export it through NFS or Samba.

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.
