Abstract: Power conservation logic for a storage node operates in parallel with an emergency shutdown process in which an emergency power source is engaged and data and metadata are destaged from volatile memory to non-volatile managed drives. The power conservation logic serially implements power conservation actions until enough reserve power is available to complete the emergency shutdown process. The power conservation logic may learn how much power savings are realized from each conservation action and adjust the order in which the conservation actions are serially implemented, e.g. in order from greatest to least power consumption reduction.

Abstract: Telemetry data gathered from active deployed SAN nodes is used to create a machine learning model that predicts storage system performance, e.g. in terms of response time. The telemetry data may be filtered to remove outlier values and less relevant information before creating the training dataset. Engineered features may be created that include types of data that are not present in the telemetry data. For example, data types from the telemetry data may be combined to create engineered features that are more relevant than the individual data types. The engineered features are included in the training dataset. The machine learning model may be used to test possible configurations for a planned SAN node based on expected workload and performance requirements. Outputted data may include satisfactory configurations for a planned storage system.
