摘要： Systems, methods, and computer readable media for improving synchronization performance after partially completed writes are disclosed. According to one aspect, a method for improving synchronization performance after partially completed writes includes receiving, from a requesting entity, data to be written to storage. The data to be written is sent to each of a plurality of data storage entities, including a primary data storage entity and at least one secondary data storage entity for providing a duplicate of the primary data storage entity. For each of the plurality of data storage entities, the portion of the data that was stored to the respective data storage entity is determined. For each of the secondary data storage entities, the portions of the secondary data storage entity that do not contain a duplicate of the corresponding portion of the primary data storage entity are identified as requiring synchronization, while the portions of secondary data storage entity that contain a duplicate of the corresponding portion of the primary data storage entity are identified as not requiring synchronization.

摘要： Systems, methods, and computer readable media for an adaptive block allocation mechanism are disclosed. According to one aspect, a method for allocating slices of storage in a storage medium based on scores is disclosed. The method occurs at a storage processor for controlling access to a storage medium divided into a plurality of logical slices of storage. The method includes determining one or more scores associated with one or more slices. Determining one or more scores includes combining plural dissimilar characteristics of the slice into a single value. The method further includes receiving a slice allocation request, and in response to the slice allocation request, selecting a slice for allocation using the scores.

摘要： According to one aspect, the subject matter described herein includes a method for tier-based slice allocation and data relocation in a data storage array. The method is performed at a data storage array including physical data storage capacity being logically divided into one or more logical units (LUs) and each of the one or more LUs being further subdivided into one or more slices, where the data storage array includes a resource pool being divided into a plurality of resource groupings, where each resource grouping includes one or more resources of a common type. The method includes receiving a slice allocation request for allocating a slice from the data storage array, where the slice allocation request includes at least one constraint. In response to receiving the slice allocation request, a slice that honors the at least one constraint is allocated.
