Abstract: Embodiments of the present disclosure provide a method and apparatus for data processing. The apparatus comprises: a dividing unit configured to divide, based on a predetermined policy, computation workload for data in a storage node into at least one sub-workload; and a dispatching unit configured to dispatch the at least one sub-workload to at least one of the storage node and a computing node that is physically separate from the storage node for execution of the at least one sub-workload with computing resources in the at least one of the storage node and the computing node.

Abstract: Embodiments of the present disclosure provide a method and apparatus for determining a cause of performance degradation of a storage system. The method comprises: monitoring performance of the storage system according to a predetermined policy; generating a performance degradation event from a result of the monitoring based on system performance baseline; in response to performance degradation event, obtaining information about the performance degradation; and offline analyzing the information to determine the cause of the performance degradation. Compared with the prior art, embodiments of the present disclosure can manage the system performance degradation effectively and continuously to minimize running costs and enable current performance profiling tools in the manner of insertion.

Abstract: Embodiments of the present disclosure relate to a data storage management method and system that is configured to: to monitor access conditions of data stored in a plurality of storage devices, wherein the plurality of storage devices are divided into a plurality of storage device tiers based on their respective characteristics; determine active degrees of the respective data based on the access conditions of the respective data; control movement of the respective data among the plurality of storage device tiers based on the active degrees of the respective data, such that the respective data are stored in the storage device tiers adapted to their respective active degrees.
