摘要： An embodiment of the present invention is directed to a method and system for making intelligent failover decisions within a server cluster. The method includes receiving temperature information and location information using RFID technology and detecting an error condition. The method further includes responsive to the error condition, selecting a failover target based on said temperature information and location information and transferring operations from a portion of a storage cluster to the failover target based on the selecting.

摘要： A key set is registered. The registering the key set includes registering a first shared data resource key. The first shared data resource key includes a first identifier associating a first process with a first shared data resource. The registering the key set further includes registering a second shared data resource key, and the second shared data resource key includes a second identifier associating a second process with a second shared data resource. A failure of a first process is detected, and in response to the detecting the failure of the first process, the first shared data resource key is de-registered. The second shared data resource key remains registered after the de-registering the first shared data resource key.
摘要翻译：注册一个密钥集。注册密钥集包括注册第一共享数据资源密钥。第一共享数据资源密钥包括将第一进程与第一共享数据资源相关联的第一标识符。注册密钥组还包括注册第二共享数据资源密钥，并且第二共享数据资源密钥包括将第二进程与第二共享数据资源相关联的第二标识符。检测到第一处理的故障，并且响应于检测到第一处理的故障，第一共享数据资源密钥被解除注册。在取消注册第一共享数据资源密钥之后，第二共享数据资源密钥保持登记。

摘要： A cluster of virtual servers includes a plurality of physical nodes, where each physical node executes virtualization software which implements a virtualization environment in which one or more virtual server machines execute. The virtualization software executed by each physical node may enable the virtualization environment implemented by the physical node to be dynamically changed. Some types of configuration changes to the virtualization environment may take a significant amount of time to perform, e.g., several seconds or longer. While the configuration change is taking place, the physical node may be unable to respond to messages sent by other physical nodes in the cluster of virtual servers. The nodes may execute message broadcast software which implements a message broadcast protocol which takes into account the dynamic configuration changes to the virtualization environments of the nodes in the cluster of virtual servers so that these periods of unresponsiveness can be handled gracefully.
摘要翻译：一组虚拟服务器包括多个物理节点，其中每个物理节点执行实现一个或多个虚拟服务器机器执行的虚拟化环境的虚拟化软件。由每个物理节点执行的虚拟化软件可以使由物理节点实现的虚拟化环境能够被动态地改变。对虚拟化环境的一些类型的配置更改可能需要大量的时间来执行，例如几秒钟或更长时间。在进行配置更改时，物理节点可能无法响应虚拟服务器群集中其他物理节点发送的消息。节点可以执行消息广播软件，其实现消息广播协议，其考虑到虚拟服务器集群中的节点的虚拟化环境的动态配置改变，使得可以优雅地处理这些无响应时段。
