A distributed data storage system and method comprising a highly integrated mass storage controller system permitting distributed management and control of data storage is disclosed. The present invention in some preferred embodiments permits mass storage media to be made available on a network in a fashion to permit global access, while automatically handling many high-level file access and data integrity/security/control functions normally associated with a host operating system. This integration and redistribution of functionality permits spatial diversification of data resources, automatic mirroring of data, fault isolation, data security, and a plethora of other control functions to be integrated into the mass storage device. This integration permits peer-to-peer communication between mass storage devices to both unburden the host data consumers but also isolate the data management functions from the data presentation functions normally associated with host systems. Exemplary embodiments of the present invention as applied to specific preferred system contexts include but are not limited to distributed data storage in a networked environment, brokered data access metering, database access/control, data backup, journaling, checkpointing, and automated software distribution.

A method, computer readable media, and apparatus of hierarchical-based communication session and data distribution management that indexes client's communication preferences and network attribute information. Indexing is used to generate dynamic group membership lists that map into communication groups. Indexing is replicated at control nodes in the network overlay to allow distributed management of group membership. Send/receive operations are decoupled through data distribution and the indexing structure. Senders and receivers register their group communication interests to a parent node in the hierarchy. The session control structure aggregates client interest and dynamically updates replicas at control nodes which are selected according to the changes in registered client interest. The indexing structure has self-managing properties for automatic clustering based on client session and data interests, and dynamic partitioning of the session/data interest attribute space. Group membership is managed by querying the indexed session/data distribution management structure and mapping output to communication groups.

A groupware management system for collaborative groups is disclosed that is scalable to support large, dynamic, multiple, and other virtual VPNs. The system may introduce a graph (or hierarchical) structure to the VPN, providing multiple master nodes controlling membership in subsets of the collaborative group. Use of multiple master nodes in a graph-structured (or hierarchical) network topology often relaxes the need for a single, centralized, globally consistent view of VPN group membership, and enables distribution of the management burden among multiple master nodes. Membership in the VPN may be changed dynamically by the second master node for the member nodes of the second subset, without requiring the first master node to dynamically update its group membership records to reflect the change and in many cases without even having to notify the first master node (and vice versa), for example. In further embodiments, the use of multiple master nodes may increase the reliability and efficiency of VPNs, such as by enabling load balancing of master node tasks. Fail-over mechanisms may also be used to transparently re-route management tasks to an alternate master node especially in the case of failure of the current master node serving a given member node.
