Abstract: The present inventions provide a cluster administration system that is capable of handling a cluster having one or more computing devices. The number of computing devices that may be included in a cluster is limited only by practical considerations rather than software or hardware limitations. In one embodiment, a cluster administration system includes a cluster of computing devices, one of the computing devices being an owner. The cluster further includes a resource. Direct access to the resource by the computing devices is controlled by the owner of the cluster. The cluster administration system also includes an arbiter. The arbiter and the cluster are in communication with each other and a network, the cluster providing the network with access to the storage device. The arbiter controls the admission of new computing devices to the cluster when the owner of the cluster is incapable of admitting the new computing device. Having the arbiter outside the cluster provides greater reliability. The arbiter is not affected by failures within the cluster. One or more of the computing devices of the cluster may fail, but the administration of the cluster is not affected. The functions of the arbiter may also be distributed among several independent computing devices which can hand off the primary duties of the arbiter should one or more of the independent computing devices fail to satisfactorily perform the duties of arbitration.

Abstract translation: 本发明提供了能够处理具有一个或多个计算设备的集群的集群管理系统。 可能包含在群集中的计算设备的数量仅受实际考虑而不是软件或硬件限制的限制。 在一个实施例中，集群管理系统包括一组计算设备，其中一个计算设备是所有者。 集群还包括一个资源。 由计算设备直接访问资源由群集的所有者控制。 集群管理系统还包括仲裁器。 仲裁器和集群彼此通信，并且网络，群集为网络提供对存储设备的访问。 当集群的所有者不能接受新的计算设备时，仲裁器控制新的计算设备进入集群。 将仲裁者置于群集之外提供更高的可靠性。 仲裁器不受群集内的故障影响。 集群的一个或多个计算设备可能会失败，但集群的管理不受影响。 仲裁者的功能也可以分布在几个独立的计算设备之间，如果一个或多个独立计算设备不能令人满意地执行仲裁的责任，则可以将仲裁者的主要职责移交。
