Fig. 1 is the system of selection process flow diagram of memory body sensor of the present invention.
Embodiment
Below in conjunction with accompanying drawing, structural principle of the present invention and principle of work are described in detail:
Please refer to shown in Fig. 1, it is the system of selection process flow diagram of memory body sensor of the present invention.The system of selection of memory body sensor of the present invention is suitable for operating in one to be had on the servomechanism (Server) of dissimilar a plurality of memory bodys (DualIn-Line Memory Modules, DIMM).Wherein, the type of aforementioned memory body is the operating voltage of corresponding different memory bodys respectively, is also the memory body that servomechanism can be supported different operating voltage simultaneously.
In step S102, in baseboard management controller (Baseboard Management Controller, BMC), the memory body of each is preset respectively to a voltage security scope.That is to say, the memory body being inserted on the memory slots of servomechanism has different operating voltage separately, such as 1.35V or 1.5V etc., is also that user can be in baseboard management controller, and the memory body of default corresponding 1.35V or 1.5V is preset a voltage security scope respectively.
For instance, the voltage security scope of the memory body of corresponding 1.35V is for example 1.2V ~ 1.4V; The voltage security scope of the memory body of corresponding 1.5V is for example 1.4V ~ 1.7V.All the other are analogized.Furthermore, baseboard management controller can comprise a sensor data record (Sensor Data Record, SDR), and the default voltage security scope of aforementioned memory body can be defined in sensor data record.
In step S104, close baseboard management controller memory body sensor read voltage function forbidden energy memory body sensor.That is to say, baseboard management controller can carry out initialization by the intrarecord scanning bit of memory body sensor data (Scanning Bit), for example scanning bit is set as to " 0 ", to close the voltage function that reads of memory body sensor, and the sense operation of forbidden energy (Disable) memory body sensor.
In step S106, carry out the start self test program (Power On Self Test, POST) of Basic Input or Output System (BIOS) (Basic Input Output System, BIOS).For instance, when servomechanism comes into operation, by CPU (central processing unit) (Central Processing Unit, CPU), carry out and be stored in read-only memory (Read Only Memory, ROM) Basic Input or Output System (BIOS), to carry out the start self test program of Basic Input or Output System (BIOS).
Then,, in step S108, Basic Input or Output System (BIOS) detects one of them the type of memory body of servomechanism configuration.In order to make the servomechanism can normal operation, all memory slots on servomechanism can plug the memory body of same type, for example the memory body of the operating voltage of corresponding 1.35V or the memory body of the operating voltage of corresponding 1.5V.That is to say, servomechanism can detect by Basic Input or Output System (BIOS) the type of the memory body on the memory slots of servomechanism, the operating voltage that the type that also detects memory body is corresponding 1.35V or the operating voltage of corresponding 1.5V.
Furthermore, memory body meeting configuration information code, so that the type of recognition memory body, therefore in start self test program stage of Basic Input or Output System (BIOS), Basic Input or Output System (BIOS) is read and is inserted in the information code that the memory body on memory slots configures by CPU (central processing unit), to learn the type of aforementioned memory body, for example, be the applicable memory body of operating voltage of 1.35V or the memory body of the operating voltage of applicable 1.5V.
Then,, in step S110, baseboard management controller reads the type of detected memory body from Basic Input or Output System (BIOS).For instance, after Basic Input or Output System (BIOS) detects the type of memory body and the start self test program of Basic Input or Output System (BIOS) and completes, Basic Input or Output System (BIOS) can send the relevant information of the type of obtained memory body to baseboard management controller, makes baseboard management controller read the type of detected memory body.
In step S112, baseboard management controller, according to the type of the memory body reading, is selected the voltage security scope that detected memory body is corresponding.For instance, during operating voltage that the type of the memory body reading when baseboard management controller is corresponding 1.35V, baseboard management controller for example, in sensor data record, is selected the voltage security scope corresponding to memory body of the operating voltage of corresponding 1.35V, for example 1.2V ~ 1.4V.During operating voltage that the type of the memory body reading when machine board management controller is corresponding 1.5V, baseboard management controller is for example in sensor data record, select the voltage security scope corresponding to memory body of the operating voltage of corresponding 1.5V, for example 1.4V ~ 1.7V.
In step S114, start baseboard management controller memory body sensor read voltage function activation memory body sensor.That is to say, the baseboard management controller for example intrarecord scanning bit of sensor data (Scanning Bit) is set as " 1 ", and the sense operation of activation (Enable) memory body sensor.
For instance, when operating voltage that the type of memory body is corresponding 1.35V, baseboard management controller can be set as " 1 " by the scanning bit of the type of corresponding this memory body in sensor data record, and the memory body sensor of the type of corresponding this memory body of activation carries out corresponding sense operation.
On the other hand, when operating voltage that the type of memory body is corresponding 1.5V, baseboard management controller can be set as " 1 " by the scanning bit of the type of corresponding this memory body in sensor data record, and activation memory body sensor carries out corresponding sense operation.
In step S116, memory body sensor reads the voltage of detected memory body, and compares voltage and the voltage security scope of memory body.That is to say, after baseboard management controller activation memory body sensor, memory body sensor can read the voltage of detected memory body, and the voltage of this memory body and voltage security scope are compared.
For instance, when operating voltage that the type of memory body is 1.35V, the voltage security scope that this memory body is corresponding is for example 1.2V ~ 1.4V.Wherein, the minimum threshold value of the voltage security scope that the memory body of the operating voltage that 1.2V is corresponding 1.35V is corresponding (Threshold Value), and the highest threshold value of voltage security scope corresponding to the memory body of the operating voltage that 1.4V is corresponding 1.35V.Therefore,, when memory body sensor reads after the voltage of aforementioned memory body, can compare voltage and 1.2V ~ 1.4V voltage security scope of this memory body.
On the other hand, during operating voltage that the type of memory body is 1.5V, the voltage security scope that this memory body is corresponding is for example 1.4V ~ 1.7V.Wherein, the minimum threshold value of the voltage security scope that the memory body of the operating voltage that 1.4V is corresponding 1.5V is corresponding (Threshold Value), and the highest threshold value of voltage security scope corresponding to the memory body of the operating voltage that 1.7V is corresponding 1.5V.Therefore,, when memory body sensor reads after the voltage of aforementioned memory body, can compare the voltage security scope of voltage and the 1.4V ~ 1.7V of this memory body.
Then,, in step S118, confirm that the voltage of detected memory body is whether within the scope of voltage security.When the voltage of confirming detected memory body is not within the scope of voltage security, enter step S120, the baseboard management controller information that gives a warning, corresponding to mechanism to notify user to carry out.
On the other hand, when the voltage of confirming detected memory body is within the scope of voltage security, get back to step S116, memory body sensor reads the voltage of detected memory body again, and relatively voltage and the voltage security scope of memory body, with the voltage that continues to monitor memory body whether still within the scope of voltage security.Thus, according to dissimilar memory body, select the voltage security scope that detected memory body is corresponding, and start voltage read functions and the activation memory body sensor of the memory body sensor of corresponding detected memory body, effectively to avoid the voltage of memory body not within the scope of voltage security, memory body still operates, and baseboard management controller can not send corresponding warning message, and easily causes the situation that memory body damages to occur.
The system of selection of the memory body sensor of embodiments of the invention, it utilizes the type of the memory body that detects servomechanism configuration, again according to the type of memory body, select the voltage security scope corresponding to type of this memory body, and voltage read functions and the activation memory body sensor of the memory body sensor of the type of corresponding this memory body of startup, to read the voltage of memory body, and whether the voltage that judges memory body within the scope of voltage security, and then judges whether according to this to produce warning message.Thus, can avoid the voltage of memory body not within the scope of voltage security, memory body still operates, and easily causes the situation of damage to occur.
