摘要： A system and method for mitigating memory errors in a computer system. Faulty memory is identified and tested by a memory manager of an operating system. The memory manager may perform diagnostic tests while the operating system is executing on the computer system. Regions of memory that are being used by software components of the computer system may also be tested. The memory manager maintains a stored information about faulty memory regions. Regions are added to the stored information when they are determined to be faulty by a diagnostic test tool. Memory regions are allocated to software components by the memory manager after checking the stored information about faulty memory regions. This ensures a faulty memory region is never allocated to a software component of the computer system.

摘要： A Metadata server described herein is configured to generate a metadata table optimized for data durability and recovery. In generating the metadata table, the metadata server associates each possible combination of servers with one of the indices of the table, thereby ensuring that each server participates in recovery in the event of a server failure. In addition, the metadata server may also associate one or more additional servers with each index to provide added data durability. Upon generating the metadata table, the metadata server provides the metadata table to clients or servers. Alternatively, the metadata server may provide rules and parameters to clients to enable those clients to identify servers storing data items. The clients may use these parameters and an index as inputs to the rules to determine the identities of servers storing or designated to store data items corresponding to the index.

摘要： A plurality of servers configured to receive a plurality of requests associated with a plurality of byte sequences are described herein. The requests for each byte sequence are received by a single one of the servers. Each server is further configured to serially process the requests it receives while the other servers also perform serial processing of requests in parallel with the server. Also, the requests for each byte sequence are transmitted to the single one of the servers by a plurality of clients, each client independently identifying the single one of the servers for the byte sequence based on system metadata.

摘要： The creation of an effective circuit between a sender device and a receiver device over the packet-switched network is described herein. To establish the effective circuit, the sender device sends a request to the receiver device through the packet-switched network. The request is associated with a bandwidth reservation from the receiver device for reception of a message from the sender device. The receiver device receives multiple requests from multiple sender devices and reserves bandwidth for at least one of the sender devices. The receiver device then sends a response to the at least one sender device providing clearance to send the message to the receiver device using the reserved bandwidth, the request and response establishing the effective circuit. The receiver device may also decline the requests of the other sender devices, causing the other sender devices to send other requests to other receiver devices.

摘要： A metadata server configured to maintain storage assignment mappings in non-persistent storage is described herein. The tract storage assignment mappings associate servers with storage assignments, the storage assignments representing the data stored on the servers. Responsive to a failure, the metadata server receives the storage assignments from the servers and rebuilds the storage assignment mappings from the storage assignments. The metadata server is also configured to enable clients to operate during a recovery process for a failed server by providing the storage assignment mappings to the clients during the recovery process. Also during the recovery process, the replacement server for the failed server conditionally overwrites stored data with other data received from other servers as part of the recovery process. The replacement server conditionally overwrites based on version information associated with the data and version information associated with the other data, the version information being associated with one or more versions of the storage assignment mappings

摘要： A system including a plurality of servers, a client, and a metadata server is described herein. The servers each store tracts of data, a plurality of the tracts comprising a byte sequence and being distributed among the plurality of servers. To locate the tracts, the metadata server generates a table that is used by the client to identify servers associated with the tracts, enabling the client to provide requests to the servers. The metadata server also enables recovery in the event of a server failure. Further, the servers construct tables of tract identifiers and locations to use in responding to the client requests.
