Abstract: Embodiments maintain high availability of software application instances in a fault domain. Subordinate hosts are monitored by a master host. The subordinate hosts publish heartbeats via a network and datastores. Based at least in part on the published heartbeats, the master host determines the status of each subordinate host, distinguishing between subordinate hosts that are entirely inoperative and subordinate hosts that are operative but partitioned (e.g., unreachable via the network). The master host may restart software application instances, such as virtual machines, that are executed by inoperative subordinate hosts or that cease executing on partitioned subordinate hosts.
Abstract translation: 实施例在故障域中保持软件应用程序实例的高可用性。 主机由主机监控。 下级主机通过网络和数据存储发布心跳。 至少部分地基于所发布的心跳，主主机确定每个从属主机的状态，区分完全不起作用的从属主机和可操作但被分区的下级主机（例如，经由网络不可达）。 主主机可以重新启动由不能操作的下属主机执行的软件应用程序实例，例如虚拟机，或者停止在分区的下级主机上执行。

Abstract: A system for monitoring a virtual machine executed on a host. The system includes a processor that receives an indication that a failure caused a storage device to be inaccessible to the virtual machine, the inaccessible storage device impacting an ability of the virtual machine to provide service, and applies a remedy to restore access to the storage device based on a type of the failure.
Abstract translation: 用于监视在主机上执行的虚拟机的系统。 系统包括处理器，其接收指示故障导致存储设备对虚拟机不可访问，不可访问的存储设备影响虚拟机提供服务的能力，并且应用补救来恢复对存储设备的访问 基于失败的类型。

Abstract: Exemplary methods, apparatuses, and systems determine a list of virtual machines to be subject to a corrective action. When one or more of the listed virtual machines have dependencies upon other virtual machines, network connections, or storage devices, the determination of the list includes determining that the dependencies of the one or more virtual machines have been met. An attempt to restart or take another corrective action for the first virtual machine within the list is made. A second virtual machine that is currently deployed and running or powered off or paused in response to the corrective action for the first virtual machine is determined to be dependent upon the first virtual machine. In response to the second virtual machine's dependencies having been met by the attempt to restart or take corrective action for the first virtual machine, the second virtual machine is added to the list of virtual machines.

Abstract: Recovery of virtual machines when one or more hosts fail includes identifying virtual machines running on the remaining functioning hosts. Some of the identified powered on virtual machines are suspended in favor of restarting some of the failed virtual machines from the failed host(s). A subsequent round of identifying virtual machines for suspension and virtual machines for restarting is performed. Virtual machines for suspension and restarting may be identified based on their associated “recovery time objective” (RTO) values or their “maximum number of RTO violations” value.
Abstract translation: 当一个或多个主机出现故障时恢复虚拟机包括识别在其余功能主机上运行的虚拟机。 一些已识别的带电虚拟机被暂停，有利于从失败的主机重新启动一些故障虚拟机。 执行下一轮识别用于重新启动的悬挂和虚拟机的虚拟机。 可以根据其相关的“恢复时间目标”（RTO）值或其“最大RTO违规数量”值来识别用于暂停和重新启动的虚拟机。

Abstract: The present disclosure is related to systems and methods for scheduling and managing series of snapshots. An example method can include estimating a transfer time to transfer a first snapshot of a virtual computing instance (VCI) to a first snapshot series, and estimating a transfer time to transfer a second snapshot of the VCI to a second snapshot series. The method can further include determining a first schedule time to start a transfer of a first series of snapshots and determining a second schedule time to start a transfer of a second series of snapshots, wherein the first schedule time and the second schedule time are based at least in part on a respective recovery point objective (RPO). In some embodiments, the method can further include scheduling a point in time to record a next snapshot based at least in part on the shorter schedule time of the first schedule time and the second schedule time.

Abstract: A system for proactive resource reservation for protecting virtual machines. The system includes a cluster of hosts, wherein the cluster of hosts includes a master host, a first slave host, and one or more other slave hosts, and wherein the first slave host executes one or more virtual machines thereon. The first slave host is configured to identify a failure that impacts an ability of the one or more virtual machines to provide service, and calculate a list of impacted virtual machines. The master host is configured to receive a request to reserve resources on another host in the cluster of hosts to enable the impacted one or more virtual machines to failover, calculate a resource capacity among the cluster of hosts, determine whether the calculated resource capacity is sufficient to reserve the resources, and send an indication as to whether the resources are reserved.
Abstract translation: 用于保护虚拟机的主动资源预留系统。 该系统包括一组主机，其中主机集群包括主主机，第一从机主机和一个或多个其他从机主机，并且其中第一从机主机在其上执行一个或多个虚拟机。 第一个从属主机被配置为识别影响一个或多个虚拟机提供服务的能力的故障，并计算受影响的虚拟机的列表。 主主机被配置为接收在主机群集中的另一个主机上预留资源的请求，以使受影响的一个或多个虚拟机故障转移，计算主机群集之间的资源容量，确定计算出的资源容量是否足够 保留资源，并发送资源是否保留。
