Jimmy Tang's entry to the Open Repositories 2012 DevCSI Developer Challenge.
His idea was be to add FEC codes to the persistance layer in digital preservation, archival, storage systems. (To add a redundant array of inexpensive network devices to systems such as iRODS, Fedora-Commons, Hydra?). The idea is to have raid at the network level for the backend of a repository system.
The background to this is that securely storing data by replication at the network level, while it is effective, it can be expensive as the system scales. Unless the system can buy enough disk in bulk to get the bulk discount it will can be expensive.
