    • Embodiments include a power-efficient failover method. The method includes operating a primary server at a normal operating state in which program code is executed, and dynamically generating a backup of the results of the executed program code while in the normal operating state. The method further includes operating a redundant server at a reduced power state in which less power is consumed than in the normal operating state of the primary server. The workload of the primary server may be assumed according to the backup in response to a failure of the primary server. The power state of the redundant server is managed, including maintaining the redundant server in the reduced power state prior to detecting a failure of the primary server and increasing the power state of the redundant server and assuming the workload of the primary server in response to the failure of the primary server.
    • 实施例包括功率高效的故障切换方法。 该方法包括在执行程序代码的正常操作状态下操作主服务器,并且在正常操作状态下动态生成所执行程序代码的结果的备份。 该方法还包括以比主服务器的正常操作状态消耗更少功率的功率降低的状态来操作冗余服务器。 可以根据备份响应主服务器的故障来假定主服务器的工作负载。 管理冗余服务器的电源状态,包括在检测到主服务器故障之前维护冗余服务器处于降低功率状态,并增加冗余服务器的电源状态,并假定主服务器的工作负载响应于 主服务器故障。

    • In a data center that includes a number of chassis, with each chassis including a chassis management module and a number of slots, each slot associated with a service processor: network address assignment includes discovering, by a chassis management module of a particular chassis, one or more other chassis management modules; negotiating, by the chassis management module with the other chassis management modules via IPv6 data communications, a chassis-specific range of IPv4 addresses available for assignment to service processors of the particular chassis; providing, by the chassis management module to the service processors of the particular chassis, in dependence upon the chassis-specific range of IPv4 addresses, a base IPv4 address; and determining, by each service processor of the particular chassis, in dependence upon the base IPv4 address and a slot identifier of the slot associated with the service processor, an IPv4 address for the service processor.
