摘要： A computer-implemented method for determining the healthiness of nodes within computer clusters may include (1) identifying a computer cluster that includes a plurality of nodes configured to provide substantially continuous availability of at least one application, (2) identifying at least one operating system kernel installed on at least one of the nodes, (3) configuring the operating system kernel to (a) asynchronously monitor performance of the node and (b) determine, based at least in part on the node's performance, whether the node is sufficiently healthy to execute the application, (4) receiving a notification from the operating system kernel that indicates that the node is not sufficiently healthy to execute the application, and then (5) performing at least one action configured to enable the computer cluster to provide substantially continuous availability of the application despite the unhealthy node. Various other systems, methods, and computer-readable media are also disclosed.

摘要： A method for defining and managing a composite service group for a cluster based computer system is disclosed. The method includes instantiating a plurality of application units on a cluster based computer system, wherein the application units implement a business service. The method further includes receiving a composite service group definition, wherein a composite service group enumerates application units, out of the plurality of application units, that implement the business service, and generating a consolidated status of the composite service group. The business service is then started (online)/stopped (offline)/migrated/failed-over/failed-back in accordance with the consolidated status, as a single unit, by using the composite service group.
摘要翻译：公开了一种用于为基于群集的计算机系统定义和管理组合服务组的方法。该方法包括在基于群集的计算机系统上实例化多个应用单元，其中应用单元实现业务服务。所述方法还包括接收组合服务组定义，其中组合服务组枚举在所述多个应用单元中执行所述业务服务的应用单元，以及生成所述组合服务组的统一状态。然后，通过使用组合服务组，将业务服务作为单个单元，根据统一状态（在线）/停止（脱机）/迁移/故障切换/故障恢复。

摘要： Various systems and methods for implementing site-level sub-cluster dependencies are disclosed. One such method involves initiating failover of a first service group from a first cluster site to a second cluster site. The first service group includes one or more resources of an application. The method then identifies at least one dependent service group at the first cluster site. The dependent service group is either a parent or a child of the first service group. The method then involves initiating failover of the dependent service group from the first cluster site to the second cluster site.
