Abstract: Techniques for a data storage cluster and a method for maintaining and updating reliability data and reducing data communication between nodes, are disclosed herein. Each data object is written to a single data zone on a data node within the data storage cluster. Each data object includes one or more data chunks, and the data chunks of a data object are written to a data node in an append-only log format. When parity is determined for a reliability group including the data zone, there is no need to transmit data from other data nodes where the rest of data zones of the reliability group reside. Thus, inter-node data communication for determining reliability data is reduced.

Abstract: Examples are disclosed for identifying duplicated media content in a plurality of media files. In some examples, according to a media file format, media content sequences may be located and duplicated media content sequences identified. For these examples, at least a portion of the identified duplicated media content sequences may then be deleted or not stored at a storage system. Other examples are described and claimed.

Abstract translation: 本文公开了用于数据存储集群的技术以及用于维护和更新可靠性数据并减少节点之间的数据通信的方法。 每个数据对象被写入数据存储集群内的数据节点上的单个数据区。 每个数据对象包括一个或多个数据块，数据对象的数据块以仅追加日志格式写入数据节点。 当对包括数据区的可靠性组确定奇偶校验时，不需要从可靠性组的其余数据区所在的其他数据节点发送数据。 因此，用于确定可靠性数据的节点间数据通信被减少。
