摘要： An adaptive idle detection method determines whether software defined data centers (SDDCs) in a hyperconverged infrastructure (HCI) environment are idle. Idleness may be quantified via a coefficient of variation (CV) against resource usage, so as to adapt the idle detection method to SDDCs with different hardware specifications and workloads. Management overhead may also be filtered out by the idle detection method, and the idle detection method may use idleness scores to further reduce overhead.

摘要： Example methods relating to maintain a quality of service of a cloud application are described. One example method includes monitoring a workload metric of a virtual machines which is running the cloud application, creating additional one or more virtual machines, isolating the additional one or more virtual machines, and determining whether the workload metric exceeds a threshold. In response to determining that the workload metric exceeds the threshold, the method includes deisolating the additional one or more virtual machines to support the cloud application. Otherwise, the method includes maintaining one or more virtual machines being isolated.

摘要： Example methods and systems for request handling with automatic scheduling are described. In one example, a computer system may receive, from multiple client devices, respective multiple requests that are generated and sent according to a first set of control parameters. Based on the multiple requests, request characteristic(s) may be monitored to determine whether an automatic scheduling condition is satisfied. In response to determination that the automatic scheduling condition is satisfied, the computer system may assign a second set of control parameters to the respective client devices and instruct the client devices to generate and send respective multiple subsequent requests according to the second set of control parameters to cause a modification of the request characteristic(s).

摘要： One example method to perform object-based load balancing in a distributed storage system of a virtualization system supported by a cluster of host machines may include determining, by a first host machine in the cluster, whether any host machine in the cluster has affinity to a site. The method may also include determining, by the first host machine, whether to distribute affinity Internet small computer system interface (iSCSI) targets owned by the first host machine to at least the second machine based on a first balance objective associated with the site, and after having considered the first balance objective, determining, by the first host machine, whether to distribute iSCSI targets without affinity owned by the first host machine to other host machines in the cluster based on a second balance objective associated with the cluster.

摘要： The disclosure herein describes enabling use of a logical unit for data storage in a distributed storage system using a plurality of backend data objects. Based on receiving instructions to create a logical unit of a logical unit size, a target backend object size to be used with the logical unit is determined, and a plurality of backend objects for allocation to the logical unit is calculated. The backend objects are allocated to the logical unit and a metadata mapping associated with the logical unit is generated. The metadata mapping associates logical block addresses of the logical unit to the allocated backend objects. The logical unit is linked with the metadata mapping in an input/output (I/O) service and, based on the linked metadata mapping, I/O traffic is routed to and from the logical unit. Using multiple backend objects enhances flexibility and efficiency of data storage on the distributed storage system.

摘要： The disclosure provides automated update notifications. Embodiments include receiving, by a cloud provider, a request to manage updates for a computing device communicating with the cloud provider via a network. Embodiments include registering an agent at the computing device with the cloud provider as a recipient for an automated update notification based on configuration details of the computing device and detection of an update item related to an aspect of the configuration details. Embodiments include identifying, by the agent, the configuration details of the computing device, the configuration details comprising details of a hardware configuration of the computing device and a software configuration of the computing device. Embodiments include monitoring one or more databases for the update item. Embodiments include transmitting the automated update notification to the agent based on detection of the update item in the one or more databases.

摘要： A method is provided for a hyper-converged storage-compute system to implement an active-active failover architecture for providing Internet Small Computer System Interface (iSCSI) target service. The method intelligently selects multiple hosts to become storage nodes that process iSCSI input/output (I/O) for a target. The method further enables iSCSI persistent reservation (PR) to handle iSCSI I/Os from multiple initiators.

摘要： A method for a processor to provide a chart of a performance metric in a collection interval includes creating regions by dividing the collection interval into regions of increasingly smaller time intervals and determining a mean and a variance for each region based on data points in that region, sorting the regions by their variances and means, and processing the sorted regions. Processing the sorted regions includes removing any child region when its parent region has a variance that substantially represents the child region, and replacing any two neighboring or intersecting regions with a merged region comprising the two neighboring or intersecting regions when the merged region has a variance that substantially represents the two neighboring or intersecting regions. The method further includes generating the chart by visually indicating highest ranking regions by variance in the chart and displaying the chart or transmitting the chart over a computer network.

摘要： A decentralized method for generation and management of health monitoring related tasks in a hyperconverged infrastructure (HCl) environment is provided. The hosts in the HCl environment each include a health agent and a task manager. The health agent collects health results from health checks and stores the health results in a shared database that is shared by the hosts. The task manager generates a health monitoring related task in response to the health results being indicative of a change in health status, and stores the health monitoring related task in a task pool that is also shared by the hosts. Any of the hosts can obtain and execute the health monitoring related tasks in the task pool based on a task priority and load balancing criteria.

摘要： Certain Embodiments described herein relate to configuring the network-storage stack of two devices (e.g., physical or virtual) communicating together (e.g., an initiator and a target, as defined below) with Internet Small Computer Systems Interface (iSCSI) extension for remote direct memory access (RDMA) iSER, which is a protocol designed to utilize RDMA to accelerate iSCSI data transfer. The iSER protocol is implemented as an iSER datamover layer that acts as an interface between an iSCSI layer and an RDMA layer of the network-storage stacks of the two devices. Using iSER in conjunction with RDMA allows for bypassing the existing traditional network protocol layers (e.g., TCP/IP protocol layers) of the devices and permits data to be transferred directly, between the two devices, using certain memory buffers, thereby avoiding memory copies taking place when the existing network protocol layers are used.
