Abstract: Techniques for performing space accounting for volume families. The techniques include maintaining two counters for each volume family, including a first counter that tracks a first amount of physical space allocated to volumes in the volume family based on the number of pages written to the volumes, and a second counter that tracks a second amount of physical space owned by the volume family, and maintaining a third counter for each volume in each branch of the volume family that tracks a number of pages among a total number of pages written to the volume that were overwritten in the immediate sequential next volume in the same branch as the volume. By maintaining, for each volume family, the first counter and the second counter, and, for each volume in the volume family, the third counter, space accounting metrics can be obtained that allow data storage activities to be performed efficiently.

Abstract: Systems and methods for caching data in artificial neural network computations are disclosed. An example method may comprise receiving, by a communication unit, data and a logical address of the data, the data being associated with the ANN, determining, by a processing unit coupled to the communication unit and to a plurality of physical memories and based on the logical address and physical parameters of the physical memories, a physical address of a physical memory of the plurality of physical memories, and performing, by the processing unit, an operation associated with the data and the physical address. The determination of the physical address can be based on a usage count of the data in the ANN computation or a time lapse between a time the data is written to the physical memory and a time the data is used in the ANN computation.

Abstract: A computer-implemented method according to one embodiment includes monitoring and storing historical data access to image data by a container within a container environment, identifying or predicting that a container is to be started utilizing the image within the container environment, predicting data to be accessed by the container, based on the historical data access by the image, and initiating a copy-on-write (COW) for the data to be accessed by the container, in response to identifying or predicting that the container is to be started.

Abstract: A switch-based inter-device notational data movement system includes a first processing system in a first chassis that provides a first thread, a second processing system in a second chassis that provides a second thread, each of which are coupled to a memory system by a switch device. A controller device coupled to the switch device receives a data transfer communication from the first thread requesting to transfer data to the second thread. That data stored in a first portion of the memory system associated with the first thread in a memory fabric management database included in the switch device. The controller device then modifies notational reference information in the memory fabric management database to disassociate the first portion of the memory system and the first thread and associate the first portion of the memory system with the second thread, allowing the second thread to reference the data using request/respond operation.

Abstract: A method and system for storage exhaustion estimation. Specifically, the method and system disclosed herein entail deriving a timeline for the depletion of available storage capacity on a backup storage array based on the data backup dynamics of various user clients. The timeline may deduce storage capacity availability in terms of future successful backup cycles, which may serve to address critical issues involving the administration of the backup storage array.

Abstract: A method of operating a cache in a computing device includes, in response to receiving a memory access request at the cache, determining compressibility of data specified by the request, selecting in the cache a destination portion for storing the data based on the compressibility of the data and a persistent fault history of the destination portion, and storing a compressed copy of the data in a non-faulted subportion of the destination portion, wherein the persistent fault history indicates that the non-faulted subportion excludes any persistent faults.
