摘要： An improved method is provided for managing workload on a multi-server computer system. In one embodiment, a subset of servers is selected according to an anticipated net workload. The remaining servers in the system may be powered off to conserve energy and prolong equipment life. Workload is dynamically apportioned among the subset of servers at selected intervals to more uniformly distribute the mean and variance of the workload among the subset of servers. More particularly, the mean and the variance for each of a plurality of workload units are equally weighed in determining a ranking of the workload units. The workload units may be ordered according to a mathematical combination of the mean and variance, such as the sum or product of mean and variance for each workload unit. The workload units are allocated among the subset of servers in according to rank, such as by assigning the workload units to the servers in a reverse round-robin fashion according to rank. Predictive power management schemes such as DVS and DVFS may then be used to control power to the servers.

摘要： Embodiments include systems and methods for selectively cooling heat-generating electronic components in an enclosure. According to one embodiment, an enclosure houses a plurality of heat-generating electronic components. Air enters the enclosure at the front and is exhausted at the rear. After passing through one or more upstream components, air diverges into at least first and second airstreams within the enclosure. The first airstream is re-cooled by a cooling system having a thermoelectric cooling module. The thermoelectric cooling module is configured such that a first side is cooled and a second side is heated in response to an applied voltage. A voltage regulator may govern the voltage in response to one or more temperatures sensed within the rack system.

摘要： Systems and methods for detecting and analyzing elevated temperatures at a component rack to identify and characterize air recirculation anomalies. In one embodiment, temperatures are sensed in proximity to an air intake of the component rack. Temperature sensors communicate with a workstation having system management software including a thermal management component for analyzing air intake temperatures. Predefined temperature differentials (PTD) are established, corresponding to expected temperature differentials between the selected locations in the absence of any appreciable recirculation. The PTD provides a threshold for comparing with “actual” temperature differentials (ATD) to identify the presence and/or mode of recirculation. If an ATD exceeds a corresponding PTD for a predefined time interval, a signal is output. The mode of recirculation, such as left-side, right-side, or dual-surface recirculation, may be determined using as few as four temperature sensors positioned at a zone of interest (ZOI).

摘要： A fan controller causes a fan assembly to flow air through a computer system at a variable airflow rate to cool the computer system. The ambient air temperature to the computer system is detected, and the controller varies the airflow rate as a function of the ambient temperature within an ambient temperature range having an upper limit. The upper limit on the defined ambient temperature range that is used by a fan speed control algorithm may be selectively reduced from a default value in response to electronic input, such from a user or a software object. Correspondingly, the controller limits the air flow rate to a reduced value corresponding to the reduced upper limit. The reduction in stranded power that results from reducing the upper limit on the ambient temperature may be re-allocated, such as to other racks in the data center.

摘要： Thermal diagnostic systems and methods are provided for improved detection of airflow anomalies in a computer system. In particular, processor load is selectively increased to amplify the effects caused by any airflow anomaly that may be present in the computer system. Workload migration may be used to shift processor load from another node to a target node. Artificial load may also be generated on the target node. The processor load increased to a level sufficient that an airflow anomaly would cause a detectable temperature difference at the selected node. The processor load may be increased by an amount computed to generate this detectable temperature difference. Alternatively, the processor load may be increased by a predetermined amount of between 40% and 100% of full processor utilization. While at the increased processor load, actual temperature sensed by temperature sensors may be compared to temperatures predicted from the model to detect the presence or absence of an airflow anomaly.

摘要： A system and method for establishing and maintaining date information associated with an electronic device. The system is typically configured to prompt a user to enter or otherwise establish a valid date at some point after power is applied to the system. After establishing a valid date, the real time clock is configured to maintain real-time date/time information. Upon determining that a valid date has been set, the system may subsequently obtain date/time information from the real time clock and store the obtained date and time in the non-volatile memory as the in-service date. The system may be enabled to determine if, subsequent to establishing an in-service date, the user altered the date/time information in a manner that indicated an intent to extend the warranty period beyond the manufacturer specified warranty period. In an embodiment suitable for use in conjunction with a server blade, the system includes a main processor and a service processor that handles low-level functions associated with the server blade. The in-service date information may be stored in a non-volatile memory of the service processor. This non-volatile memory may be implemented as an EEPROM that includes connections or pins supporting an externally accessible bus such as an I2C bus. In this embodiment, the system may further include a readout device configured to connect to the service processor EEPROM through the externally accessible bus to enable a technician to retrieve the in-service date without regard to the functionality of the main processor(s) and system memory.

摘要： A method for co-operative thermal management of a number of independent electronic devices housed within a common enclosure that includes designating a priority number and measuring a temperature for each of the independent electronic devices. Next, for each of the independent electronic devices, the measured temperature is evaluated to determine if it exceeds a threshold value for the independent electronic device. If the measured temperature exceeds a threshold value, a count-down value is initialize to the designated priority number of the independent electronic device. Following which, the count-down value is evaluated to determine if it is equal to zero. If the count-down value is equal to zero, the independent electronic device is powered down. However, if the count-down value is not equal to zero, a specified time interval is allowed to expire before the count-down value is decremented and re-evaluated to determine if it is equal to zero.
