Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
The present invention proposes a kind of method of indirectly carrying out the exploitation of EAT measuring ability, select by the minimum sensor of Overall Power Consumption variable effect for the server lacking EAT detection part by analytic demonstration, and by different loads and working environment combined test, confirm the optimized algorithm of EAT, the method does not need to modify to server hardware to increase EAT measuring ability, and the impact that server workload change detects EAT can be got rid of, improve by algorithm optimization the precision that indirect method detects EAT simultaneously.
Before realizing the method, below work is needed to prepare or build following hardware device: (1) mainboard sensor placement schemes; (2) server pressurized control program; (3) ambient temperature control device; (4) electric thermo-couple temperature testing tool (5) BMC control system.Wherein:
Mainboard sensor placement figure for confirming temperature sensor location, for selecting by the less some temperature sensors of complete machine load effect.
Server pressurized control program: pressurized control program, for providing different pressure loads, is convenient to get rid of components and parts heating to the impact of EAT detection.
Ambient temperature control device: for the acquisition of development data in EAT measuring ability performance history, by the environment temperature of adjustment server work, the change curve of mainboard temperature sensor with environment temperature can be obtained, for finding the optimized algorithm of EAT matching.
Electric thermo-couple temperature testing tool: comprise T-shaped thermocouple wire, data acquisition unit, obtain real EAT information by detecting three position temperature in about server front end, this value cannot be obtained by BMC control system, can only as design reference.
BMC control system: this part is divided into hardware circuit and software program, does not change in the invention to hardware, is added to the fitting algorithm of air temperature in software.
As shown in Figure 1, its specific implementation process is:
One, customer demand is understood, confirmed service type number and configuration: because different hardware configuration can impact server air quantity, and the configuration of internet big customer's common procurement server is comparatively single, therefore can obtain a common configuration develops, and improves the precision of functional realiey.
Two, obtain mainboard temperature sensor, i.e. sensor layout, this means suitable we need the mainboard model getting server collocation.
Three, select the sensor away from pyrotoxin, for detecting in subsequent development process: during server stress load change, the heat of generation affects less on this region sensor, therefore can slacken the impact of pressure load as far as possible.
Four, test platform is built according to client's configuration.
Five, from low temperature to hot environment, detect zero pressure, 50%, the actual EAT of server and mainboard temperature sensor data (point of the 3rd step confirmation) under 100% pressure: this part gets the temperature information data under various composite condition, for next step process.
Six, data summarization, get rid of temperature sensor data larger with the fluctuation of pressure load delta data under identical ring temperature, retain by the minimum sensor reading of load effect: because server stress applies when changing, mainboard electric current, complete machine internal temperature field all can change, therefore the sensor data away from pyrotoxin also can change, for getting rid of impact as far as possible, we select the enterprising one-step optimization in basis of sensor in the 3rd step, select best temperature sensor data.
Seven, data processing, obtains the relationship between mainboard sensor and actual EAT: the impact excluding pressure load, and mainboard temperature sensor data variation is only relevant with environment temperature, therefore can be easy to the linear relationship found between the two.
Eight, in fitting formula write BMC software program, for monitoring server EAT: so just can in display server EAT information under administration interface.
Nine, BMC provides external communication interface, EAT information can be supplied to computer lab management control system: exploitation EAT function is mainly used for machine room and controls, and therefore needs to ensure that computer lab management control system can get the EAT data of server.
By above operation, we do not need to increase extra hardware circuit design, only need the adjustment carrying out software view, utilize the existing temperature sensor of hardware, can realize EAT read functions, and this implementation is zero cost, high precision, is easy to operation.
Above-mentioned embodiment is only concrete case of the present invention; scope of patent protection of the present invention includes but not limited to above-mentioned embodiment; any according to the invention a kind of indirectly carry out claims of the method for EAT measuring ability exploitation and the those of ordinary skill of any described technical field to its suitable change done or replacement, all should fall into scope of patent protection of the present invention.
