A system and method is described that accesses a network persistent memory unit (nPMU). One embodiment comprises a primary region corresponding to a predefined portion of a primary network persistent memory unit (nPMU) communicatively coupled to at least one client processor node via a communication system, wherein the primary region is assigned to a client process running on the client processor node and is configured to store information received from the client process; and a mirror region corresponding to a predefined portion of a mirror nPMU communicatively coupled to the client processor node via the communication system, wherein the mirror region is assigned to the client process and is configured to store the information received from the client process.

Communication-link-attached persistent memory system

One embodiment of the present invention provides a distributed, differential electronic-data backup and archiving system that includes client computers and cells. Client computers execute front-end-application components of the distributed, differential electronic-data backup and archiving system, the front-end application components receiving data objects from client computers and sending the received data objects to cells of the distributed, differential electronic-data backup and archiving system for storage. Cells within the distributed, differential electronic-data backup and archiving system store the data objects, each cell comprising at least one computer system with attached mass-storage and each cell storing entire data objects as lists that reference stored, unique data chunks within the cell, a cell storing all of the unique data chunks for all data objects stored in the cell.

Method and system for scaleable, distributed, differential electronic-data backup and archiving

Various embodiments of systems and methods for remotely configuring network memory are disclosed. One method embodiment, among others, comprises identifying a first device as having authority to control a memory device from a remote location, and writing start-up or reset parameters to memory of the memory device from the remote location, wherein the start-up or reset parameters are used to enable remote control of the memory device corresponding to remote direct memory access (RDMA) operations.

Remote configuration of persistent memory system ATT tables

One embodiment of the present invention includes a method for routing a data object, comprising a sequence of data units, to a particular component data-storage system, or particular group of component data-storage systems, within a distributed, differential electronic-data storage system by selecting one or more subsequences of data units from the data object, computing a characteristic value from the selected subsequences, computing an index from the characteristic value; and directing the data object to the particular component data-storage system, or to the particular group component data-storage systems, identified by the computed index.

Content-based, compression-enhancing routing in distributed, differential electronic-data storage systems

One embodiment of the present invention provides a distributed, differential electronic-data storage system that includes client computers, component data-storage systems, and a routing component. Client computers direct data objects to component data-storage systems within the distributed, differential electronic-data storage system. Component data-storage systems provide data storage for the distributed, differential electronic-data storage system. The routing component directs data objects, received from the clients computers, through logical bins to component data-storage systems by a compression-enhancing routing method.

Distributed differential store with non-distributed objects and compression-enhancing data-object routing

One embodiment of the present invention provides an efficient data-object-related-request-routing method and component used within a dynamic, distributed data-storage system for efficiently routing data objects to component data-storage systems when component data-storage systems frequently become unavailable and new component data-storage systems are frequently added to the dynamic, distributed data-storage system. The data-object-related-request-routing method is employed in data-object store operations and data-object retrieval operations. The data-object store and retrieval operations, in turn, are based on identifying certain preferred component data-storage systems within the distributed data-storage system by a component-data-storage-system-ranking method.
