    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： Systems, methods, and computer readable media for triggering and coordinating pool storage reclamation are disclosed. According to one example, the method includes receiving an issued hint triggered by the execution of a data storage optimization operation applied to a mapped logical unit (MLU), wherein the MLU is one of a plurality of MLUs residing in a storage array, and computing an unused portion amount of an allocated storage space in the MLU, wherein the allocated storage space comprises a plurality of slices. If the unused portion amount exceeds a predetermined threshold value, detecting at least one of the slices to be released from the allocated storage space. The method also includes transferring data contained in a detected slice to at least one of the remaining slices in the allocated storage space, and removing the detected slice from the allocated storage space in the MLU to a common storage pool in the storage array, wherein the removed slice is allocated to any one of the plurality of MLUs.
