  FIG. 1 shows a configuration of an information processing system 1 according to the present embodiment. The information processing system 1 includes, for example, a monitoring device 10 that is a service processor, a plurality of system boards 20 that are monitored by the monitoring device 10, and a reaction processing unit 30 that is, for example, an MBC (Maintenance Bus Controller). A management terminal 5 is connected to the information processing system 1, and the management terminal 5 is operated by an administrator.

  The system board 20 includes a cooling fan 2001, a CPU (Central Processing Unit) 2002, a DIMM (Dual Inline Memory Module) 2003, a crossbar 2004, and a PSU (Power Supply Unit) 2005. Can operate as a single computer. Note that other hardware components may be installed on the system board 20.

  The PSU 2005 supplies power to the cooling fan 2001, CPU 2002, DIMM 2003, and crossbar 2004, and the cooling fan 2001, CPU 2002, DIMM 2003, and crossbar 2004 operate using the supplied power. In the PSU 2005, the power supplied to the hardware components on the system board 20 is measured as “power consumption”.

  A temperature sensor is attached to or included in the cooling fan 2001, the CPU 2002, the DIMM 2003, and the crossbar 2004. The temperature sensor of the cooling fan 2001 measures the intake air temperature, which is the temperature of air taken from outside the information processing system 1. The temperature sensor of the CPU 2002 measures the temperature of the CPU 2002. The temperature sensor of the DIMM 2003 measures the temperature of the DIMM 2003. The temperature sensor of the cross bar 2004 measures the temperature of the cross bar 2004.

  The reaction processing unit 30 controls the rotation speed level (for example, the duty value level) of the cooling fan 2001 and the power supply from the PSU 2005 based on an instruction from the monitoring device 10.

  The monitoring apparatus 10 includes a CPU 1001, a RAM (Random Access Memory) 1002, and a ROM (Read Only Memory) 1003. The ROM 1003 stores firmware 1004 for executing the processing of the present embodiment.

  The firmware 1004 is loaded into the RAM 1002 by the CPU 1001 and executed, thereby realizing various functions as shown in FIG. FIG. 2 shows a functional block diagram of the monitoring device 10. The monitoring apparatus 10 includes a data storage unit 101, a first control unit 102, a second control unit 103, a monitoring unit 104, an output unit 105, a monitoring data storage unit 106, a record storage unit 107, and message data. Storage unit 108. The monitoring data storage unit 106, the record storage unit 107, and the message data storage unit 108 are provided in the RAM 1002 or other storage device.

  The monitoring unit 104 periodically acquires sensor data (intake air temperature data, data of each component temperature, etc.) and power consumption data from the system board 20 by I2C (Inter-Integrated Circuit). And stored in the monitoring data storage unit 106. The monitoring unit 104 includes state data stored in the monitoring data storage unit 106 (in this embodiment, power state data, power-on time data, active replacement data for the cooling fan 2001, and cooling fan 2001). The data of the operation state, etc.) is updated when the state changes. The monitoring unit 104 detects that the intake air temperature has exceeded the upper threshold value and has fallen below the lower threshold value, and that the component temperature has exceeded the upper threshold value and has fallen below the lower threshold value. The monitoring unit 104 acquires the sensor data of the corresponding system board 20 from the corresponding system board 20, and acquires the acquired sensor data and the status data of the corresponding system board 20 stored in the monitoring data storage unit 106. Notify the second control unit 103.

  The second control unit 103 executes a process of determining the rotation speed level of the cooling fan 2001 based on the data stored in the data storage unit 101 and the sensor data and state data received from the monitoring unit 104.

  The first control unit 102 periodically executes a process of determining the rotation speed level of the cooling fan 2001 based on the sensor data stored in the monitoring data storage unit 106.

  The output unit 105 executes a process of outputting an instruction to the reaction processing unit 30 and a process of outputting FRU (Field Replacement Unit) data and the like.

  Next, processing executed by the monitoring apparatus 10 will be described with reference to FIGS.

  First, a process periodically executed by the first control unit 102 will be described with reference to FIG. This process is performed for each system board 20, but for the sake of simplicity, the process performed for one system board 20 (hereinafter referred to as the target system board 20) will be described as an example. I do.

  The first control unit 102 reads the latest data of the intake air temperature of the target system board 20 from the monitoring data storage unit 106. Then, the first control unit 102 determines whether the intake air temperature is lower than a predetermined threshold (FIG. 3: step S1). The predetermined threshold value in step S1 may be larger than an upper threshold value described later.

  If the intake air temperature is equal to or higher than the predetermined threshold (step S1: No route), the process proceeds to step S5. On the other hand, when the intake air temperature is lower than the predetermined threshold (step S1: Yes route), the first control unit 102 reads the latest data of the temperature of each component of the target system board 20 from the monitoring data storage unit 106. . Then, the first control unit 102 determines whether the temperature of any one of the components (in this embodiment, the temperature of the CPU 2002, the temperature of the DIMM 2003, and the temperature of the crossbar 2004) is equal to or higher than a predetermined threshold (step S3). ). The predetermined threshold value in step S3 is determined for each part, and may be larger than an upper threshold value described later.

  When any one of the component temperatures is equal to or higher than a predetermined threshold (step S3: Yes route), the first control unit 102 outputs an instruction for increasing the rotation speed level of the cooling fan 2001 to the reaction processing unit 30. (Step S5). Then, the process ends. In response to this, the reaction processing unit 30 performs control so as to increase the rotation speed level of the cooling fan 2001, so that each component is further cooled.

  On the other hand, when any of the component temperatures is less than the predetermined threshold (step S3: No route), the first control unit 102 reads power consumption data for the target system board 20 from the monitoring data storage unit 106. Then, the first control unit 102 determines whether the power consumption is constant or decreased for a predetermined time (step S7). Since the sensor data is periodically acquired, the determination in step S7 is performed using the sensor data from a predetermined time before the time point in step S7. For example, when the power consumption is within a certain range for a predetermined time, it is determined that the power consumption is constant for a predetermined time. When the power consumption at the time of step S7 is less than the power consumption before the predetermined time, it is determined that the power consumption is decreasing. However, the determination may be performed by another method.

  If the power consumption is not constant for a predetermined time and does not decrease (step S7: No route), the process ends. On the other hand, when the power consumption is constant or decreasing for a predetermined time (step S7: Yes route), the first control unit 102 instructs the reaction processing unit 30 to decrease the rotation speed level of the cooling fan 2001 by one. Output (step S9). Then, the process ends. In response to this, the reaction processing unit 30 performs control to lower the level of the rotation speed of the cooling fan 2001, so that the power consumption of the cooling fan 2001 can be reduced.

  In the case of the system board 20 as described above, most of the power is consumed by an ASIC (Application Specific Integrated Circuit) chip such as the CPU 2002 and the crossbar 2004 or the DIMM 2003, and the component temperature changes after the power consumption changes. Therefore, it is possible to predict a change in component temperature by monitoring the power consumption. For example, when there is no abnormality in the intake air temperature and the component temperature and the power consumption is constant or decreased for a predetermined time, it is predicted that the component temperature will decrease.

  Next, processing executed by the monitoring unit 104 will be described with reference to FIGS.

  First, the monitoring unit 104 reads the latest intake air temperature data stored in the monitoring data storage unit 106. Then, the monitoring unit 104 detects that the intake air temperature has exceeded the upper threshold value or has fallen below the lower threshold value (FIG. 4: step S11).

  The upper threshold and the lower threshold will be described with reference to FIGS. 5 and 6.

  FIG. 5 shows an example of the upper threshold and the lower threshold. FIG. 5 shows the intake air temperature, the upper threshold value, and the lower threshold value for the CPU 2002, DIMM 2003, and crossbar 2004. In the present embodiment, when the value exceeds the upper threshold and when the value falls below the lower threshold, it is detected by the monitoring unit 104, and when the value falls below the upper threshold and the value exceeds the lower threshold In this case, detection by the monitoring unit 104 is not performed.

  FIG. 6 shows the relationship between the change in the intake air temperature and the upper and lower threshold values. In FIG. 6, the vertical axis represents the intake air temperature, the horizontal axis represents time, the solid line with the word “upper side” represents the upper threshold, and the broken line with the word “lower” represents the lower threshold. Represents. In the example of FIG. 6, detection is performed at t1, t3, t4, t6, and t8, but detection is not performed at t2, t5, and t7.

  Returning to the description of FIG. 4, the monitoring unit 104 detects that the intake air temperature has exceeded the upper threshold or the intake air temperature has fallen below the lower threshold (hereinafter, the corresponding system board). Sensor data (referred to as 20) is acquired from the corresponding system board 20 (step S13).

  The monitoring unit 104 reads the status data of the corresponding system board 20 from the monitoring data storage unit 106 (step S15).

  The monitoring unit 104 transmits the sensor data acquired in step S13 and the state data read in step S15 to the second control unit 103 (step S17). Then, the process ends.

  FIG. 7 shows an example of sensor data and state data transmitted to the second control unit 103. In the example of FIG. 7, the intake air temperature data, the temperature data of each component, and the power consumption data are shown as sensor data, and the power status data, the power-on time data, and the cooling fan 2001 are shown as the status data. Data on active exchange and data on the operating state of the cooling fan 2001 are shown. The power state data is data indicating whether the power is on. The power-on time data is data of the time elapsed since the last power-on. The data regarding the active replacement of the cooling fan 2001 is data indicating whether or not the cooling fan 2001 is undergoing active replacement. The operation state data of the cooling fan 2001 is data indicating whether the cooling fan 2001 is operating normally. In addition, data indicating the event that has occurred is further transmitted to the second control unit 103.

  In addition, a process executed by the monitoring unit 104 will be described separately from the process described above with reference to FIG.

  First, the monitoring unit 104 reads the latest component temperature data stored in the monitoring data storage unit 106. Then, the monitoring unit 104 detects that any one of the component temperatures exceeds the upper threshold value or falls below the lower threshold value (FIG. 8: Step S21).

  The monitoring unit 104 detects sensor data of the system board 20 (hereinafter referred to as the corresponding system board 20) in which it is detected that the component temperature has exceeded the upper threshold value or that the component temperature has fallen below the lower threshold value. Is acquired from the corresponding system board 20 (step S23).

  The monitoring unit 104 reads the status data of the corresponding system board 20 from the monitoring data storage unit 106 (step S25).

  The monitoring unit 104 transmits the sensor data acquired in step S23 and the state data read in step S25 to the second control unit 103 (step S27). Then, the process ends.

  As described above, when the intake air temperature and the component temperature exceed the upper threshold value or fall below the lower threshold value, the second control unit 103 can perform the process of optimizing the rotation speed level of the cooling fan 2001. It becomes like this.

  Next, processing executed by the second control unit 103 will be described with reference to FIGS. 9 to 13.

  First, the second control unit 103 receives sensor data and state data from the monitoring unit 104 (FIG. 9: Step S31).

  The second control unit 103 identifies one unprocessed record from the data storage unit 101 (step S33).

  FIG. 10 shows an example of data stored in the data storage unit 101. In the example of FIG. 10, the condition about the power supply state, the condition about the power-on time, the condition about the intake air temperature, the condition about the temperature of the CPU 2002, the condition about the temperature of the DIMM 2003, and the temperature of the crossbar 2004 , Conditions for hot replacement of the cooling fan 2001, conditions for the operating state of the cooling fan 2001, conditions for power consumption, priority, rotation speed level, and message number are stored. The The higher the value, the higher the priority. The number of revolutions increases as the level value increases.

  As indicated by the record in the first line of FIG. 10, when the power is not turned on, the component temperature does not rise, so the rotation speed level is set to zero. As shown in the record on the second line, when the time elapsed since the power was turned on is short, the air staying on the system board 20 is discharged, so the rotation speed level is set to 5. As indicated by the records in the third to fifth lines, the higher the intake air temperature, the higher the rotational speed level.

  The second control unit 103 determines whether or not each condition included in the record specified in step S33 is satisfied (step S35).

  When any of the conditions included in the record specified in step S33 is not satisfied (step S37: No route), the process proceeds to step S41. On the other hand, when each condition included in the record specified in step S33 is satisfied (step S37: Yes route), the record specified in step S33 is stored in the record storage unit 107 (step S39).

  The second control unit 103 determines whether there is an unprocessed record in the data storage unit 101 (step S41). If there is an unprocessed record (step S41: Yes route), the process returns to step S33. On the other hand, when there is no unprocessed record (step S41: No route), the process proceeds to step S43 in FIG.

  Shifting to the description of FIG. 11, the second control unit 103 determines whether or not there is a record in the record storage unit 107 (step S43). If there is no record in the record storage unit 107 (step S43: No route), the process ends.

  On the other hand, when there is a record in the record storage unit 107 (step S43: Yes route), the second control unit 103 determines whether there are a plurality of records in the record storage unit 107 (step S45).

  When there are not a plurality of records in the record storage unit 107 (step S45: No route), the record stored in the record storage unit 107 is specified, and the process proceeds to step S49. On the other hand, when there are a plurality of records in the record storage unit 107 (step S45: Yes route), the second control unit 103 identifies a record having the highest priority among the plurality of records (step S47). When there are a plurality of records having the same priority, one record is specified at random, for example.

  The second control unit 103 specifies the message, action, and FRU corresponding to the message number included in the specified record from the message data storage unit 108 (step S49).

  FIG. 12 shows an example of data stored in the message data storage unit 108. In the example of FIG. 12, event information, a message to be displayed, a message number, information on an action to be executed (that is, countermeasure), and FRU information are stored.

  The output unit 105 outputs the rotation speed level and message number included in the specified record, and the message, action, and FRU specified in step S49 to the management terminal 5 (step S51). Note that data such as mail may be transmitted to the portable terminal operated by the administrator. Further, data may be transmitted to an apparatus (for example, a printer) having a printing function.

  FIG. 13 shows an example of output data. In the example of FIG. 13, the rotation speed level, the message number, the message, the action, and the FRU are output.

  The output unit 105 outputs an instruction for rotating the cooling fan 2001 at the rotation speed level included in the specified record to the reaction processing unit 30 (step S53). Then, the process ends. As a result, the reaction processing unit 30 can rotate the cooling fan 2001 at an optimum rotational speed from a comprehensive viewpoint.

  FIG. 14 shows an example of the rotational speed control in the present embodiment. In FIG. 14, the horizontal axis represents time, and a power consumption graph, an intake air temperature graph, and a rotation speed level are shown. An alternate long and short dash line 1401 represents normal power consumption, a broken line 1402 represents an upper threshold value of the intake air temperature, and a broken line 1403 represents a lower threshold value of the intake air temperature.

  When the intake air temperature exceeds the upper threshold, the rotational speed level is increased from 2 to 3. Thereafter, when it is confirmed that the power consumption is constant or decreased for a predetermined time, the rotational speed level is lowered from 3 to 2. When the intake air temperature decreases and falls below the lower threshold, the rotational speed level is lowered from 2 to 1. As a result, when the intake air temperature starts to rise and the intake air temperature exceeds the upper threshold, the rotation speed level is increased from 1 to 2.

  FIG. 15 shows another example of the rotational speed control in the present embodiment. In FIG. 15, the horizontal axis represents time, and a power consumption graph, a component temperature graph, and a rotation speed level are shown. A broken line 1501 represents the threshold value of step S3, a one-dot chain line 1502 represents normal power consumption, a broken line 1503 represents an upper threshold value of the component temperature, and a broken line 1504 represents a lower threshold value of the component temperature.

  When it is confirmed that the power consumption is constant or decreased for a predetermined time, the rotation speed level is lowered from 2 to 1. As a result, the component temperature rises and exceeds the upper threshold, but the rotational speed level is maintained. When the component temperature further rises and exceeds a predetermined threshold, the rotational speed level is increased from 1 to 2. When it is confirmed that the power consumption is constant or decreased for a predetermined time, the rotation speed level is lowered from 2 to 1.

  As described above, according to the present embodiment, the control is appropriately performed so that the rotation speed level of the cooling fan 2001 does not become higher than necessary, so that the power consumed by the rotation of the cooling fan 2001 is reduced. Will be able to.

  In a system in which a plurality of system boards 20 are mounted, a temperature abnormality may be detected across the plurality of system boards 20, and in such a case, the root cause of the temperature abnormality should be specified. Is difficult. Therefore, if the rotation speed of the cooling fan 2001 related to the root cause is not set appropriately, it takes time to eliminate the temperature abnormality, or the temperature abnormality is not eliminated depending on circumstances. According to the present embodiment, the rotational speed of the cooling fan 2001 can be set from a comprehensive point of view, so that the temperature abnormality can be eliminated.

  In addition, since a high priority is set for a record with a high rotation speed level, a safer operation can be performed.

  In addition, since no dedicated parts are used, it is possible to realize general-purpose control, and it is possible to cope with changes in design (for example, parts change, speed level change, reaction change, etc.). Easy.

  Although one embodiment of the present invention has been described above, the present invention is not limited to this. For example, the functional block configuration of the monitoring apparatus 10 described above may not match the actual program module configuration.

  Further, the configuration of each table described above is an example, and the configuration as described above is not necessarily required. Further, in the processing flow, the processing order can be changed if the processing result does not change. Further, it may be executed in parallel.

  In addition, the present embodiment can be applied to a system that uses a cooling device other than the cooling fan 2001.

  The embodiment of the present invention described above is summarized as follows.

  The monitoring device (for example, the monitoring device 10) according to the first aspect of the present embodiment includes (A) the conditions regarding the component temperatures of the information processing device to be monitored (for example, the system board 20) and the power supply of the information processing device. A data storage unit (for example, the data storage unit 101) that stores a plurality of records each including a condition regarding the time elapsed since the input, and information on the number of rotations corresponding to each of the plurality of records; ) Based on information acquired from the information processing apparatus, a record satisfying each condition is specified from among a plurality of records stored in the data storage unit, and a rotation speed corresponding to the specified record is specified from the data storage unit A first specifying unit (for example, the second control unit 103), and (C) an output unit that outputs an instruction to rotate the cooling fan of the information processing device at the number of rotations specified by the first specifying unit (example) Having a field output unit 105) and.

  Since the rotational speed of the cooling fan can be determined from a comprehensive viewpoint, the rotational speed of the cooling fan can be optimized. In addition, by optimizing the rotation speed of the cooling fan, it is possible to suppress the occurrence of problems such as supercooling and to reduce the power consumed by the cooling fan.

  In addition, each of the plurality of records includes a condition regarding the power consumption of the information processing apparatus, a condition regarding the intake temperature of the cooling fan, a condition regarding whether or not the cooling fan is undergoing active replacement, and the cooling fan operates normally. It may further include at least one of a condition regarding whether or not the power is on and a condition regarding whether or not the power is turned on. The cooling fan can be rotated at a more appropriate rotational speed.

  The data storage unit may further store the priority in association with each of the plurality of records. And a 1st specific part may specify a record based on a priority, when the number of the records with which each condition is satisfied is 2 or more. The cooling fan can be rotated at a more appropriate rotational speed.

  The monitoring apparatus may further include (D) a determination unit (for example, the first control unit 102) that determines whether the power consumption of the information processing apparatus is constant for a predetermined time or more or is decreased for a predetermined time or more. . The output unit (c1) gives an instruction to reduce the number of rotations of the cooling fan when the determination unit determines that the power consumption of the information processing apparatus is constant for a predetermined time or more or is decreased for a predetermined time or more. It may be output. If the power consumption is constant for a predetermined time or more, or if the power consumption is decreasing for a predetermined time or more, it is presumed that the component temperature does not increase at present. Therefore, if the processing as described above is executed, it is possible to suppress wasteful power consumption.

  The output unit (c2) identifies the field exchange unit identification information corresponding to the record identified by the first identification unit and the countermeasure information to be executed, and executes the identified field exchange unit identification information. Information on countermeasures to be taken may be output. Work and countermeasures according to the actual situation can be performed.

  The monitoring method according to the second aspect of the present embodiment includes (E) a condition for each component temperature of the information processing apparatus to be monitored and a condition for the time elapsed since the information processing apparatus was turned on. Based on the information acquired from the information processing apparatus (F) from the data storage unit that stores a plurality of records each including the rotation speed information corresponding to each of the plurality of records, each condition among the plurality of records is The record to be established is specified, (G) the rotation speed corresponding to the specified record is specified from the data storage unit, and (H) an instruction to rotate the cooling fan of the information processing apparatus at the specified rotation speed Includes processing to output.

  A program for causing the processor to perform the processing according to the above method can be created, and the program can be a computer-readable storage medium such as a flexible disk, a CD-ROM, a magneto-optical disk, a semiconductor memory, a hard disk, or the like. It is stored in a storage device. The intermediate processing result is temporarily stored in a storage device such as a main memory.
