    • A server chassis includes an uninterruptible power supply, and a server including a controller. The uninterruptible power supply is configured to provide a reserve power when a primary power is lost, and to send a power loss signal when the primary power is lost. The controller is configured to receive a desired server uptime, to receive an indication that a power limit for the server is fixed or decreasing over the desired server, to receive the power loss signal from the uninterruptible power supply, to send a power capacity query to the uninterruptible power supply, to receive a reserve power capacity of the uninterruptible power supply in response to the power capacity query, to calculate the power limit for the server based on the reserve power capacity of the uninterruptible power supply and on the desired server uptime, and to enforce the power limit on the server.
    • 服务器机箱包括不间断电源以及包括控制器的服务器。 不间断电源被配置为在主电源丢失时提供备用电力,并且在主电源丢失时发送功率损失信号。 控制器被配置为接收期望的服务器正常运行时间,以接收指示服务器的功率限制在期望的服务器上固定或减小,以从不间断电源接收功率损耗信号,以将功率容量查询发送到 不间断电源,为了响应于电力容量查询而接收不间断电源的备用电力容量,基于不间断电源的备用电力容量和期望的服务器正常运行时间来计算服务器的功率限制, 并强制执行服务器的电源限制。
