    • A mechanism is provided for controlling the heat output of a controller by monitoring the temperature of the controller using an embedded heat sensor. The IO processor monitors the temperature and controls the rate of the IO flow to control the temperature. The IO processor accomplishes this by checking the current temperature every time it gets a timer interrupt. If the temperature becomes too high, the IO processor may slow down the processor speeds in the controller. The IO processor may also slow down the throughput by inserting a delay between each IO request processed. Furthermore, the IO processor may slow down the rate at which data is passed onto the bus. Still further, the IO processor may insert a delay between batches of IO requests. By slowing down the IO flow, the IO processor decreases the overall power consumption and, thus, controls the heat output.
    • 提供了一种用于通过使用嵌入式热传感器监视控制器的温度来控制控制器的热输出的机构。 IO处理器监控温度并控制IO流量的速率来控制温度。 IO处理器通过在每次获得定时器中断时检查当前温度来完成此操作。 如果温度过高,IO处理器可能会降低控制器中的处理器速度。 IO处理器还可能通过在处理的每个IO请求之间插入延迟来降低吞吐量。 此外,IO处理器可能会降低数据传输到总线上的速率。 此外,IO处理器可以在批次的IO请求之间插入延迟。 通过减慢IO流量,IO处理器降低总体功耗,从而控制热量输出。

    • A reply descriptor for transmission over an I/O message passing medium in response to a corresponding request message, the descriptor comprises at least one indication field that can function as a ‘flag’ to identify its type, and a content field; whereby a reply message is generated only if at least one predefined condition is not met and the content field will, accordingly, comprise information of that reply message's storage location. The content field to comprise data copied from the I/O request message if each predefined condition is met. A method of responding over an I/O message passing medium to a request message comprising the steps of: generating a reply message to the request message only if at least one predefined condition is not met; generating a reply descriptor having at least one indication field and a content field; whereby the content field comprises information of the reply message's storage location if so generated. Also, a program code on a computer readable storage medium comprising: a first program sub-code for generating a reply message to a corresponding I/O request message only if at least one predefined condition is not met. The first program sub-code comprising instructions for generating a reply descriptor having at least one indication field and a content field that comprises information of the reply message's storage location if said reply message is so generated.
