  • ROBUSTNESS IN A SCALABLE BLOCK STORAGE SYSTEM
    Publication number: 20140143367
    Abstract: A storage system that accomplishes both robustness and scalability. The storage system includes replicated region servers configured to handle computation involving blocks of data in a region. The storage system further includes storage nodes configured to store the blocks of data in the region, where each of the replicated region servers is associated with a particular storage node of the storage nodes. Each storage node is configured to validate that all of the replicated region servers are unanimous in updating the blocks of data in the region prior to updating the blocks of data in the region. In this manner, the storage system provides end-to-end correctness guarantees for read operations, strict ordering guarantees for write operations, and strong durability and availability guarantees despite a wide range of server failures (including memory corruptions, disk corruptions, etc.) and scales these guarantees to thousands of machines and tens of thousands of disks.

  • Method, apparatus and system for maintaining connections between computers using connection-oriented protocols
    Patent number: 7673038
    Abstract: The present invention provides a system, method and apparatus for maintaining a connection between a server and a client by receiving a message, determining whether to store one or more elements of the message, storing the one or more elements of the message when the one or more elements of the message are to be stored, transmitting the message, and determining whether the server has failed and when the server has failed, restoring the server to a pre-failure connection state using the one or more stored message elements.
