Abstract: A computer cluster includes a group of connected computers that work together essentially as a single system. Each computer in the cluster is called a node. Each node has a boot device configured to load an image of an operating system into the node's main memory. Sometimes the boot device of a first node experiences a problem that prevents the operating system from loading. This can affect the entire cluster. Some aspects of the disclosure, however, are directed to operations that determine the problem with the first node's boot device based on a communication sent via a first communications network. Further, the operations can communicate to the first node a copy of boot data from a second node's boot device. The copy of the boot data is sent via a second communications network different from the first communications network. The copy of the boot data can solve the first boot device's problem.
Abstract translation: 计算机集群包括一组连接的计算机，它们基本上一起工作为单个系统。 集群中的每台计算机都称为节点。 每个节点都有一个引导设备，配置为将操作系统的映像加载到节点的主存储器中。 有时，第一个节点的引导设备会遇到阻止操作系统加载的问题。 这可能会影响整个群集。 然而，本公开的一些方面涉及基于经由第一通信网络发送的通信确定第一节点的引导设备的问题的操作。 此外，操作可以从第二节点的引导设备向第一节点传送引导数据的副本。 通过不同于第一通信网络的第二通信网络发送引导数据的副本。 引导数据的副本可以解决第一个引导设备的问题。
