    Abstract: A method for analyzing a read error event is provided comprising reading a page of data stored in memory, determining a read error event for the page of data, and identifying a scope of the read error event in the memory. In another embodiment, a method for performing a preliminary read error recovery is provided comprising reading a first data unit from memory and identifying a bit error rate for a first data unit with a correction engine, determining that the bit error rate is above a threshold, accessing a data structure including entries identifying data units and read error event information associated with the data units, identifying a second data unit in an entry that matches the first data unit, and performing a preliminary read error recovery process on the first data unit using the information in the entry to reduce the bit error rate below the threshold.

    Abstract: Provided are a computer program product, system, and method for determining server write activity levels to use to adjust write cache size. Server write activity information on server write activity to the cache is gathered. The server write activity information is processed to determine a server write activity level comprising one of multiple write activity levels indicating a level of write activity. The determined server write activity level is transmitted to a storage server having a write cache, wherein the storage server uses the determined server write activity level to determine whether to adjust a size of the storage server write cache.

    Abstract: Described herein is a system and method for dynamically managing service-level objectives (SLOs) for workloads of a cluster storage system. Proposed states/solutions of the cluster may be produced and evaluated to select one that achieves the SLOs for each workload. A planner engine may produce a state tree comprising nodes, each node representing a proposed state/solution. New nodes may be added to the state tree based on new solution types that are permitted, or nodes may be removed based on a received time constraint for executing a proposed solution or a client certification of a solution. The planner engine may call an evaluation engine to evaluate proposed states, the evaluation engine using an evaluation function that considers SLO, cost, and optimization goal characteristics to produce a single evaluation value for each proposed state. The planner engine may call a modeler engine that is trained using machine learning techniques.

    Abstract: A computer determines that a utilization level of a resource has satisfied a threshold. The computer scales the allocation of the resource to the furthest of the current allocation of the resource plus a parameter and of a historical limit. The computer determines if the scaled allocation of the resource is outside the historical limit and if so, sets the historical limit equal to the scaled allocation of the resource. The computer determines whether the scaling of the allocation of the resource will result in an allocation oscillation. The computer determines if the scaled allocation of the resource is outside a boundary parameter and if so, sets the allocation of the resource equal to the boundary parameter.
