Abstract: Machines, systems and methods for dynamically implementing storlets in a storage data path. The method comprises receiving a request to perform a storage-related function on data stored on a first data storage medium in a data storage system; verifying the request by way of an authentication and authorization mechanism to prevent unauthorized access to data stored on the first data storage medium in the data storage system; and utilizing a storlet to service the request, wherein the storlet is dynamically deployed on a node in the data storage system such that the node has sufficient resources to support the storlet to service the request.

Abstract: A method for maximizing a utility of a service contract by optimizing target response time for a performance service level objective is provided. A set of criteria are provided to ensure that performance requirements for the service are met. The method comprises determining one or more usage windows for providing a service, wherein each usage window is associated with a performance requirement and a time period; extracting usage patterns for each usage window based on historical data provided from monitoring requests for service in each usage window; extracting response time per transaction associated with said requests based on historical data provided from monitoring responses provided to said requests in each usage window; and calculating optimal probability for breach in each usage window (Pi) and determining the associated target response time, based on the usage pattern for each window and the response time per transaction.

Abstract: Managing a computer system including automatically adjusting two separate component thresholds (a component threshold pair) based on a statistical model. Specifically, a first component threshold is modeled to predict violations of an SLO based on a violation of the first component threshold and a second, separate component threshold is modeled to predict a non-violation (compliance) of an SLO based on a non-violation of the second component threshold. Over time, the values of the component thresholds may change and one component threshold may be greater than the other component threshold at one time, and vice versa at another time. A component metric reading between the first and second component thresholds indicates that a prediction of an SLO violation or compliance is less certain, and a warning may be issued rather than an alert.

Abstract: Systems and methods for optimizing performance in a computing environment are provided. The system comprises means for monitoring execution of annotated logic code associated with a software component to determine whether a condition has been satisfied, wherein annotations in the logic code provide one or more details about the software component, the details being useful to a healing agent to correct a problem associated with said condition during the execution of the logic code.

Abstract: Systems and methods for optimizing memory management in a runtime environment are provided. The method comprises monitoring one or more objects loaded into primary memory of a computing system to determine if at least a first object can be removed from the primary memory; instantiating a proxy object to replace the first object in the primary memory; removing the first object from the primary memory; and monitoring calls to the proxy object to determine whether the first object is invoked by a process.
