The log records may be generated as a primary compute system performs operations. Upon receiving a request for a log record, the broker component determines whether the requested log record has been persisted in a persistent log. If the broker component determines that the log record has been persisted in the persistent log, the broker component responds to the request by causing the requested log record to be provided to the requesting entity (e.g., a secondary compute system). On the other hand, if the log record cannot yet determine that the log record has been persisted in the persistent log, the broker component prevents the log record from being provided to the requesting entity. This prevents data from being inconsistent during recovery.
US11455289B2 Shared volumes in distributed RAID over shared multi-queue storage devices
A method for data storage, in a system that includes multiple servers, multiple multi-queue storage devices and at least one storage controller that communicate over a network, includes receiving in a server, from an application running on the server, a request to access data belonging to one or more stripes. The stripes are stored on the storage devices and are shared with one or more other servers. In response to the request, the following are performed at least partially in parallel: (i) requesting one or more global locks that prevent the other servers from accessing the stripes, and (ii) reading at least part of the stripes from the storage devices speculatively, irrespective of whether the global locks are granted. Execution of the request is completed upon verifying that the speculatively-read data is valid.
