The techniques include determining a head position of a data log of a primary node and placing a marker at a corresponding position in a data log of a secondary node. In response to an IO request, the head of the primary log is moved to allocate space for writing a data entry, and the secondary node is directed to move a head of the secondary log to allocate space for writing the data entry. In response to a data entry being flushed from the primary node, a tail of the primary log is moved to reclaim allocated space for a previous data entry, and the secondary node is directed to move a tail of the secondary log to reclaim previously allocated space. In response to a tail of the secondary log coinciding with the marker position, content of the logs is synchronized.

Abstract: Systems and methods for enabling the real-time sharing of document edits are disclosed herein.

Both the high level functions and underlying activities may be analyzed to determine whether it is safe to implement the changes they represent in real-time on an endpoint. When it is determined that the changes are safe to implement, the changes will be implemented and further real-time edits will be shared. When it is determined that the edits are not safe to implement, real-time updates will be suspended until the next selected-time update, at which time real-time sharing will recommence.

Write requests may be received at different storage nodes sufficient to establish a write quorum, and stored in the replicas of the data at the storage nodes where they are received. Storage nodes maintaining incomplete views of the data may determine that each of the storage nodes maintaining a complete view of the data in the quorum set stores certain write requests, and in response, may reclaim storage space for those write requests included in the incomplete views of the data in order to store other data at the storage node.

Only those medium extents corresponding to M which R does not already have will be sent from O to R. Also, R can obtain medium extents from other source storage arrays during the replication process.

Furthermore, frequently, search term elements are missing on a webpage referenced by an Internet search result but are found on a descendant webpage thereof. Accordingly, the present invention is further directed to annotating an Internet search result consistent with the presence or absence of search term elements on both a referenced webpage and one or more descendant webpages.

Abstract: Methods and systems for storing and managing large numbers of small files. A data processing system includes clients that generate large numbers be stored on a storage device managed by a File System (FS). An Archive Server (AS) receives multiple files from the client, archives the files in larger archives, and sends the archives to the FS for storage. When requested to read a file, the AS retrieves the archive in which the file is stored, extracts the file and sends it to the requesting client. In other words, the AS communicates with the clients in individual file units, and with the storage device in archive units. The AS is typically constructed as an add-on layer on top of a conventional FS, which enables the FS to handle small files efficiently without modification.

Abstract: A cluster management system and method for synchronizing content libraries within a distributed computer system uses multiple replication processes to synchronize a subscribed content library with a publishing content library, which includes at least a consumable software item and metadata of the consumable software item. If the consumable software item of the publishing content library can be replicated at the subscribed content library using a first data replication process, then the consumable software item of the publishing content library is replicated at the subscribed content library using the first data replication process. If the consumable software item of the publishing content library cannot be replicated at the subscribed content library using the first data replication process, the consumable software item of the publishing content library is replicated at the subscribed content library using a second data replication process.

Abstract: A system on a chip or storage device has a dynamic process for handling system events that are transmitted at varying transmission rates. This dynamic process is a hybrid mode of operation that tailors the use of time stamp information according to the dynamic flow of events that are submitted in the system. Relative time stamps can be used along with explicit time stamps. Periodic wrap around events which use relative time stamps based on the periodic wrap events may be suppressed when there were no events between consecutive wrap around events. When an asynchronous event occurs during the suppression, the event is identified with a high precision time stamp (HPTS) rather than a relative time stamp. The periodic wrap around events can be re-initiated after the HPTS event is stamped.

Activities associated with the different files may include content changes in a file (e.g., edits and deletions), sharing a file, renaming a file, comments within a file, messaging, and conversations related to a file. The different storage platforms may be independent of the activity service.
