  • Goal-oriented storage management for a distributed data storage network
    Patent number: 8886705
    Abstract: A system and method for performing goal-oriented storage management for a distributed data storage network. Storage management software may execute on each node to cause the distributed data storage network to converge toward a system-wide storage goal. In various embodiments, the system-wide storage goal may be defined to accomplish any of various kinds of optimizations or performance improvements for the system, such as balancing storage utilization, achieving appropriate data replication, increasing performance, increasing fault tolerance, etc.

  • Managing routing information for a computer network
    Patent number: 8370523
    Abstract: A plurality of routing entries may be stored in a routing table. Each routing entry may include information usable for routing a message through a network. As new routing entries are received or created, each new routing entry may be added to the routing table. However, if there is not sufficient memory or storage to add the new routing entry to the routing table, then the least recently used existing routing entry in the routing table may be replaced with the new routing entry. In the event that the replaced routing entry is needed later, the replaced routing entry may be re-created.

  • Efficient search for storage objects in a network
    Patent number: 7680950
    Abstract: A system and method related to efficiently searching for an object in a network including a plurality of realms, e.g., a plurality of local area networks (LANs). The method may ensure that nodes within a LAN are able to locate objects within that LAN using only computing resources on the local LAN. Thus, expensive WAN transfers may be avoided where possible. The system may also scale to many nodes. Nodes may not be required to know about every other node in the system. Mechanisms for re-distributing object location information among nodes as nodes are added to and removed from the system are also described.

  • Efficiently linking storage object replicas in a computer network
    Patent number: 7555527
    Abstract: A system and method for efficiently linking together replicas of a storage object. The location of a first replica of the storage object may be stored on a node in a network. When new replicas of the storage object are created, the node that stores the new replica may efficiently lookup the location of the first replica and utilize the location information to perform an efficient process to link the new replica to the first replica and any other existing replicas by causing routing information to be created on various nodes.
