摘要： Systems, methods, and computer program products for mirroring dual writeable storage arrays are provided. Various embodiments provide configurations including two or more mirrored storage arrays that are each capable of being written to by different hosts. When commands to write data to corresponding mirrored data blocks within the respective storage arrays are received from different hosts at substantially the same time, write priority for writing data to the mirrored data blocks is given to one of the storage arrays based on a predetermined criterion or multiple predetermined criteria.

摘要： Provided is a remote copy system capable of guaranteeing the time ordering of data to be handled by a remote site even when the tasks at the remote site are operated across a plurality of storages or a plurality of volume groups. A consistency group consisting of a secondary journal volume and a replica is associated with a journal group consisting of a primary data volume, a primary journal volume, a secondary journal volume, and a secondary data volume. Upon backing up a secondary data volume and forming a replica, the host system issues a backup time reservation command to a storage apparatus, and the storage apparatus creates a replica by comparing the time stamp added to the journal data and the backup reservation time.

摘要： Techniques for maintaining mirrored storage cluster data consistency on systems with write back cache can employ write-intent logging and periodic log clearing. The techniques can track any outstanding I/Os, data in caches, and data that has gone out of sync between mirrored nodes due to link failures. The techniques can ensure that a power failure on any of the storage nodes does not result in inconsistent data among the storage nodes. The techniques can use gate bitmaps to log outstanding I/Os. The gate bitmaps may be periodically cleared. The clearing period may be selected as to allow enough time for all caches to be flushed and for all synchronizing I/Os to complete. Efficient queuing of I/O requests in conjunction with the efficient operation of multiple gate bitmaps can reduce performance impacts of the gating or logging operations.
摘要翻译：在具有回写高速缓存的系统上维护镜像存储集群数据一致性的技术可以采用写意图日志记录和周期性日志清除。这些技术可以跟踪任何未完成的I / O，缓存中的数据以及由于链路故障而在镜像节点之间失去同步的数据。这些技术可以确保任何存储节点上的电源故障不会导致存储节点之间的数据不一致。这些技术可以使用门位图记录未完成的I / O。门位图可能会被定期清除。可以选择清除时间段以允许足够的时间刷新所有高速缓存并使所有同步I / O完成。结合多个门位图的高效操作，I / O请求的高效排队可以降低门控或日志记录操作的性能影响。

摘要： In distributed storage environments, nodes may send replicated writes for temporal volumes and may be configured to request on-demand consistency intervals in order to allow multiple nodes to transition between timestamps for temporal data in a uniform and coordinated manner. In response to a request from a node for a consistency interval transition, a consistency interval coordinator may end a current consistency interval and start another and may provide coordination to various nodes to enable the nodes to transition from one timestamp to another, and thus from one temporal version to another, while prevent data corruption or inconsistency between the temporal versions. Additionally, periodic consistency intervals may be utilized to provide consistent and coordinated transitions between temporal timestamps. In some embodiments, replicated writes including temporal timestamp information may be stored persistent spillover logs allowing offline updating and versioning of data to temporal volumes.
摘要翻译：在分布式存储环境中，节点可以发送用于时间卷的复制写入，并且可以被配置为请求按需一致性间隔，以便允许多个节点以均匀和协调的方式在时间数据的时间戳之间转换。响应于来自节点的用于一致性间隔转换的请求，一致性间隔协调器可以结束当前的一致性间隔并启动另一个间隔，并且可以向各个节点提供协调以使节点能够从一个时间戳转换到另一个时间戳时间版本到另一个，同时防止数据损坏或时间版本之间的不一致。另外，可以利用周期性一致性间隔来提供时间时间戳之间一致和协调的转换。在一些实施例中，包括时间时间戳信息的复制的写入可以是存储的持久性溢出日志，允许将数据离线更新和版本化到时间量。

摘要： A method, system, and computer program product for providing continuous data protection for write data supplied from a host incorporating a processor device to data storage in accordance with write input/output (I/O) of an owning application is provided. The write data is identified as one of a synchronous candidate and an asynchronous candidate. The write data identified as the one of the synchronous candidate and the asynchronous candidate is transferred to at least one sidefile. The write data transferred to the at least one sidefile is secured in a nonvolatile storage journal. The nonvolatile storage journal is preset with a timeout limit applicable to write data identified as the synchronous candidate. If the timeout limit is exceeded, a loss mitigation operation to safeguard the write data identified as the synchronous candidate is performed.

摘要： A cluster of computer system nodes share direct read/write access to storage devices via a storage area network using a cluster filesystem. Access to files on the storage devices is arbitrated by the cluster filesystem using tokens. Upon detection of a change in location of the metadata server, client nodes waiting for a token are interrupted to check on the status of at least one of data and node availability.

摘要： A system and method for detecting mirror inconsistencies in a distributed storage environment. Inconsistencies between mirrors may be detected by comparing session tags among individual storage devices. Each data write may include a tag and storage devices may calculate session tags from the write tags. Additionally, a storage device may keep a history including tags from recent writes. When a client sessions ends, a metadata server may compare the respective session tags from different storage devices to determine whether the mirrors are synchronized. If the session tags do not match, the metadata server may examine the metadata histories from the storage devices to determine a cause for the discrepancy in the session tags. If examining the session histories fails to reveal the discrepancy's source, a metadata server may request individual data block checksums from storage devices to attempt a re-synchronization of the mirrored storage devices.
摘要翻译：一种用于检测分布式存储环境中镜像不一致性的系统和方法。可以通过比较各个存储设备之间的会话标签来检测镜之间的不一致。每个数据写入可以包括标签，并且存储设备可以从写入标签计算会话标签。此外，存储设备可以保留包括来自最近写入的标签的历史记录。当客户端会话结束时，元数据服务器可以比较来自不同存储设备的相应会话标签，以确定镜像是否被同步。如果会话标签不匹配，则元数据服务器可以从存储设备检查元数据历史，以确定会话标签中差异的原因。如果检查会话历史无法显示差异来源，则元数据服务器可以请求来自存储设备的单个数据块校验和以尝试镜像存储设备的重新同步。
