PowerScale OneFS vs Tahoe-LAFS

PowerScale OneFS has no write-up on Specifiction yet; its figures are above.

Tahoe-LAFS is free, open-source software for storing files across multiple servers. Before upload, a client encrypts each file with a unique key. Erasure coding distributes each file as shares, allowing recovery when some storage servers fail; the documented default uses 10 shares across at least 7 servers and can recover from any 3. A gateway checks integrity and ignores corrupted shares. Files can be immutable or mutable, with read-only or read-write access for mutable files and directories. The gateway gives access through HTTP(S) and SFTP, and a REST-style Web API supports programmatic operations. Users can run a gateway or operate a full grid of storage nodes and an introducer. Installation is documented for Windows, macOS, Linux, and BSD. The software is available under GNU GPL version 2 or later, or the Transitive Grace Period Public Licence version 1.0 or later. It is free at free. The public test grid is for experimentation, not reliable or large-scale storage.
