Abstract: Described herein is a system, and related techniques, for predicting I/O requests that are not necessarily directed to sequential sectors of a physical storage device. In some embodiments, I/O patterns that do not involve sequential-sector access, and that may be relatively long-term patterns, may be recognized. To recognize such patterns, deep machine-learning techniques may be used, for example, using neural networks. Such neural networks may be a recurrent neural network such as, for example, an LSTM-RNN. I/O streams for a workstream may be sampled for specific I/O features to produce a time series of I/O feature values of a workstream, and this time series of data may be fed to a prediction engine, e.g., an LSTM-RNN to predict one or more future I/O features values, and I/O actions may be taken based on these predicted feature values.

Abstract: Memory management that includes allocating physical memory having an append-only permission associated therewith to requesting user space applications is described. If a page frame is append-only, then data written to the page frame cannot be overwritten. Rather, any new data written to an append-only page frame must be written beginning at the next available write location within the page frame. An MMU determines whether a write request is requesting an append-only page frame, in which case, the MMU reserves the append-only page frame for the write request and consults a corresponding entry in a page table append to determine whether an offset associated with the write request is larger than a stored value in the entry that indicates the next available write location in the page frame. If so, the write request is executed and the data is written to the page frame beginning at the next available write location.

By maintaining, for each volume in a volume family, a first counter and a second counter for tracking the SnapOwnedCount and the UnsharedWithParentCount, respectively, data storage recovery can be performed more effectively, allowing selected volumes and/or portions thereof to be deleted while maintaining accurate space accounting information.

Abstract: An efficient data storage system is described. An agent software application on computing devices in a first tier processes snapshot backups and pushes them to an appliance software application on a server in a second tier. The appliance software application processes archive backups and pushes them to cloud storage in a third tier. A cloud application on a management server receives storage policy specifications from customers and promulgates the policies to the agent software application and the appliance software application. The policy specifications include a snapshot specification including a snapshot time period for backups in the second tier and an archive specification including an archive time period for backups in the third tier. The backups are created efficiently such that if a file has not changed, a reference to a file is included in a storage set rather than the data file itself. This reduces the size of storage sets.

Abstract: A garbage collection process running on a computing device is configured to track the number of garbage collection cycles that storage fragments, called extents, are persisted in storage without being modified or deleted using a lifetime counter that is implemented using metadata. At each garbage collection cycle, the extents are sorted by lifetime values. Old extents (i.e., those existing at the start of the cycle) are bucketed together by lifetime values during garbage collection into new extents (i.e., those being created during the cycle). Thus, each of the new extents includes data having similar lifetime values. The lifetime value for the new extent equals the lowest lifetime value of the old source extent plus one additional increment on the counter. As extents are organized by garbage collection lifetime, placement on storage media can be optimized according to expected endurance requirements.
