Peergos is a peer-to-peer encrypted filesystem with secure sharing of files designed to be resistant to surveillance of data content or friendship graphs. It will have a secure email replacement, with some interoperability with email. There will also be a totally private and secure social network, where users are in control of who sees what (executed cryptographically).

LizardFS is a highly reliable, scalable and efficient distributed file system. It spreads data over a number of physical servers, making it visible to an end user as a single file system.

BeeGFS (formerly FhGFS) is the leading parallel cluster file system, developed with a strong focus on performance and designed for very easy installation and management. If I/O intensive workloads are your problem, BeeGFS is the solution.
