Abstract: The present technology relates to managing workload within a storage system. A quality of service parameter proposal associated with managing incoming network traffic is generated and provided to a plurality of nodes. The generated quality of service parameter proposal to manage the incoming network traffic is modified based on a response received from the nodes. The incoming network traffic is serviced using the data from the modified quality of service parameter proposal.

Abstract: A method, non-transitory computer readable medium, and device that assists with dynamic resource reservation based on classified input/output requests includes receiving an input/output request from a client computing device. The input/output request is classified as a first priority request, wherein the first priority request has priority to a second priority request. A deadline time period to execute the received input/output request classified as the first priority request is determined and the first priority request is added to a first priority queue. The first priority request in the first priority queue is processed by assigning a plurality of reserved resources.

Abstract: Improved path management techniques for storage networks are described. In one embodiment, for example, an apparatus may comprise a processor circuit, a detection component for execution by the processor circuit to receive an advertisement of a set of paths for accessing a logical storage volume and determine whether the set of paths comprises an optimized path, and a modification component for execution by the processor circuit to, when the set of paths does not comprise an optimized path, send a first instruction to update a reporting nodes parameter for the logical storage volume to identify an owner node for the logical storage volume and a corresponding partner node. Other embodiments are described and claimed.

Abstract: Disclosed are various embodiments for managing paths in a cluster environment. The cluster environment receives a request from a client to access a logical storage volume via a selected one of a plurality of paths defined for the logical storage volume. In response to an access of the logical storage volume via one of the paths, the cluster environment updates a timestamp for the respective path that corresponds to a time of the access via the respective path. Subsequently, the cluster environment determines a remote path defined for the logical storage volume that can be removed based upon comparing a timestamp for the selected path with a timestamp for the remote path.

Abstract: Methods, non-transitory machine readable media, and computing devices that assign a quality of service (QoS) policy to an instantiated storage object. The assigned QoS policy includes a throughput parameter including a number of input/output (I/O) operations per second (IOPS) based on a storage operation block size. Storage operations are executed with the storage object according to the throughput parameter. Metadata is monitored including a size attribute of the storage object. The QoS policy is then automatically modified to adjust the throughput parameter based on the size attribute. This technology configures, manages, and scales performance provided to storage objects based on a monitored used or allocated size of the storage objects. Accordingly, this technology provides more performance for applications as storage object space is increasingly consumed by the applications, thereby improving the functionality and efficiency of storage nodes or controllers that are executing storage operations and managing I/O in storage networks.

Abstract: A system for controlling power usage in a storage cluster by dynamically controlling membership in the storage cluster is disclosed. The storage cluster includes multiple storage servers that provide access to one or more storage subsystems. The power management system uses a power management policy to set parameters for controlling membership in the storage cluster and monitors the storage cluster based on the policy. Based on the monitoring, the system detects when the number of storage servers in the storage cluster should be reduced or increased. To reduce the number, the system selects a storage server to deactivate and directs the selected storage server to migrate storage resources (e.g., data, metadata) associated with the server to a different storage server. The system then deactivates the selected storage server by directing it to transition to a low power mode. The system may increase the number of servers in the storage cluster by reversing these steps.
