摘要： In accordance with an embodiment of the invention, a method of writing and reading redundant data is provided. Data is written by storing a copy of the data along with a timestamp and a signature at each of a set of storage devices. The data is read by retrieving the copy of the data, the timestamp and the signature from each of a plurality of the set of data storage devices. One of the copies of the data is selected to be provided to a requestor of the data. Each of the storage devices of the set is requested to certify the selected copy of the data. Provided that a proof of certification of the selected copy of the data is valid, the storage devices of the set are instructed to store the selected copy of the data along with a new timestamp.

摘要： To determine files associated with one or more workflows, a trace of accesses of files in at least one server is received. The files are grouped into at least one set of files, where the files in the set are accessed together more than a predetermined number of times in the trace. Files associated with the particular workflow are identified based on the at least one set.

摘要： A remote procedure call chain is provided that replaces multiple consecutive remote procedure calls to multiple servers from a client by allowing a client to specify multiple functions to be performed consecutively at multiple servers in a single remote procedure call chain. The remote procedure call chain is executed by a sequence of multiple servers. Each server executes a service function and a chaining function of the remote procedure call chain. The chaining function uses the state of the remote procedure call chain in the sequence of servers to determine the next server to receive the remote procedure call chain, and the service function to be executed by that server. After the last service function is performed, the last server in the sequence of servers sends the results of the executed service functions to the client that originated the remote procedure call chain.
摘要翻译：提供了一个远程过程调用链，通过允许客户端指定要在单个远程过程调用链中的多个服务器上连续执行的多个函数，将多个连续远程过程调用替换为多个服务器。远程过程调用链由多个服务器的序列执行。每个服务器执行远程过程调用链的服务功能和链接功能。链接功能使用服务器序列中的远程过程调用链的状态来确定接收远程过程调用链的下一个服务器以及由该服务器执行的服务功能。在执行最后一个服务功能之后，服务器序列中的最后一个服务器将执行的服务功能的结果发送给发起远程过程调用链的客户端。

摘要： Embodiments of the present invention pertain to improving recoverability of a dataset associated with a multi-tier storage system. According to one embodiment, updates to a dataset are stored in first storage. The dataset and a point-in-time copy of the dataset reside on second storage, and the first storage provides higher reliability than the second storage. The dataset is restored using at least a subset of the stored updates in combination with the point-in-time copy in the event that the dataset is lost.

摘要： Preventing replay attacks on servers. At least one Bloom filter may be set up in a server for tracking requests received from clients. Identifying data may be generated for each request. The identifying data may be checked against the Bloom filter array. If a match is found, the message may be a replay and may be rejected. If a match is not found, the request identifying data may be added to the Bloom filter and the request may be processed.

摘要： The Heartbeat Failure Detector of the present invention, is a new, simple method and device that has several identical modules, and each module is attached to a processor in the system. Roughly speaking, the module of a processor x maintains a heartbeat counter for every other process. For each process y, the counter of y at x (called the heartbeat of y at x) periodically increases while y is alive and in the same network partition, and the counter stops increasing after y crashes or becomes partitioned away. Using such a device, x can solve the communication problem above by resending m only if the heartbeat of y at x increases. Note that if y is crashed (or partitioned away from x), its heartbeat at x stops almost immediately, and so x will also immediately stop sending copies of m to y.

摘要： According to one embodiment, a method comprises evaluating messages between nodes of a distributed computing environment. Based on timing relationships of the messages, probability of causal links between pairs of messages determined. Based on the determined probability, at least one causal path comprising a plurality of causal links is inferred. Further, an overall probability that the inferred causal path is accurate is determined. In certain embodiments, the overall probability is output for the corresponding causal path to provide an indication of the confidence of the accuracy of such inferred causal path.
