Reliable, Scalable, And High ­Performance Distributed Storage: Distributed Object Storage

Described is an efficient, scalable, and low ­overhead cluster management protocol that facilitates consistent and coherent data access through the propagation of small cluster maps that specify device membership and data distribution. This allows a dynamic cluster of semi­-autonomous OSDs to self­ manage consistent data replication, failure detection, and failure recovery while providing the illusion of a single logical object store with direct, high­ performance client access to data.

What we are trying to do?

We are attempting to mobilize the creativity and innovative capacities of the Linux and broader open source community to codify the universe of preexisting inventions in defensive publications that upon publication in the IP.COM database will immediately serve as effective prior art that prevents anyone from having a patent issued that claims inventions that have already been document in a defensive publication. In addition to creating a vehicle to utilize this highly effective form of IP rights management for known inventions, it is hoped that the community will use defensive publications as a means of codifying future inventions should the inventors prefer not to make their invention the subject of a patent disclosure and application.
