    Abstract: In a distributed system, multiple nodes of a cluster update target data using a cross-domain lock. In the distributed system, data is separated into different domains, where some data elements are part of multiple domains. Multiple nodes each store a copy of the target data, which can be part of a single domain, or part of multiple domains. Where at least one element of the target data is part of two different domains, the nodes use cross-domain locks to lock both domains for at least a portion of the data update, and update the data while the lock is active. After updating the data, the nodes can release the cross-domain lock.

    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: 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: Improved access management techniques for storage networks are described. In one embodiment, for example, an apparatus may comprise a processor circuit and an access control component for execution by the processor circuit to select a set of hosts for which to enable access to a logical storage volume of a network storage cluster, select, from among a plurality of nodes of the network storage cluster, a set of nodes via which to enable access to the logical storage volume by the set of hosts, and generate a storage configuration object comprising a parameter identifying the set of nodes. Other embodiments are described and claimed.

    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.

    Abstract translation: 公开了一种通过动态控制存储簇中的成员关系来控制存储簇中的功率使用的系统。 存储集群包括提供对一个或多个存储子系统的访问的多个存储服务器。 电源管理系统使用电源管理策略来设置用于控制存储集群中的成员资格的参数，并根据策略监视存储集群。 基于监控，系统检测存储集群中存储服务器的数量何时减少或增加。 为了减少数量，系统选择存储服务器以停用并引导所选择的存储服务器将与服务器相关联的存储资源（例如，数据，元数据）迁移到不同的存储服务器。 然后，系统通过将其转换到低功耗模式来停用所选择的存储服务器。 系统可以通过反转这些步骤来增加存储集群中的服务器数量。

    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.
