Abstract: In accordance with some embodiments, classification of input/output requests from a database to a storage system may be performed. Each input/output request may be associated with a database class, and each database class may be mapped to a quality of service policy. Thus, quality of service may be enforced such that different data blocks within the storage system of the database may be afforded appropriate quality of service.

Abstract: Examples perform predictive probabilistic deduplication of storage, such as virtualized or physical disks. Incoming input/output (I/O) commands include data, which is written to storage and tracked in a key-value store. The key-value store includes a hash of the data as the key, and a reference counter and the address of the data as the value. When a certain percentage of sampled incoming data is found to be duplicate, it is predicted that the I/O commands have become not unique (e.g., duplicate). Based on the prediction, subsequent incoming data is not written to storage, and instead the reference counter associated with the hash of the data is incremented. In this manner, predictions on the uniqueness of future data is made based on previous data, and extraneous writes and deletions from the chunk store are avoided.

Abstract: A power tool that includes a motor coupled to a drive mechanism, and a removable and rechargeable battery pack coupled to the motor to selectively provide power signals to the motor. The power tool also includes a controller configured to monitor a plurality of conditions of the power tool, such as battery pack voltage, battery pack temperature, operational current, and the like. The controller is also configured to detect one or more events related to the plurality of conditions of the power tool. If the operational current of the power tool exceeds a first threshold value, a power signal duty cycle is reduced from a first duty cycle value to a second duty cycle value to limit the amount of torque the power tool is able to generate.

Abstract: Techniques for managing space in a flash storage-based cache are provided. In one embodiment, a computer system can calculate “ratio of effective cache space” (rECS) values for a plurality of VMs, where each VM has a cache allocation comprising a subset of a global pool of cache blocks in the flash storage-based cache, and where the rECS value for the VM indicates a proportion of the subset that has been populated with cached data and re-accessed by the VM within a current time window. The computer system can further determine a new cache allocation size for at least one VM in the plurality of VMs based on the rECS values. The computer system can then adjust the number of cache blocks in the at least one VM's cache allocation based on the new cache allocation size.
