FDT is an application for efficient data transfers that is capable of reading and writing at disk speed over wide area networks (with standard TCP). It can be used to stream a large set of files across the network, so a large dataset composed of thousands of files can be sent or received at full speed, without the network transfer restarting between files. It is written in Java, runs an all major platforms, and is easy to use.
Radiant Data PeerFS is real-time peer-to-peer distributed replicating file system featuring global file and sectional locks. All read operations are performed locally, and only file changes are transmitted across the network. It supports databases such as MySQL, as well as images and documents. All nodes are active/active, allowing for load balancing. Clients can also be hot switched between nodes, eliminating downtime. It also supports AES encryption for use across the Internet.
