Description
Technical Field
The invention relates to the technical field of servers. The invention further relates to a temperature control method and a temperature control device for the hybrid hard disk.
Background
In the storage industry, Hard disks are generally classified into HDD (Hard Disk Drive) and SSD (Solid state Drive). In general, the SSD is selected for the high-end storage configuration, the HDD is selected for the low-end storage configuration, and the flash-mixed configuration in which the HDD and the SSD are mixed is selected for the middle-end storage configuration. The so-called flash-mixed configuration, also called a hybrid hard disk configuration, is a configuration in which a hard disk in a storage device includes both an HDD and an SSD.
As the application of the mixed flash configuration in the storage device becomes wider and wider, the contradiction between the heat dissipation of the hard disk and the noise reduction of the fan in the mixed flash configuration becomes more and more prominent. The operating temperature that HDD hard disks can withstand is generally low, usually below 60 ℃, while SSDs can withstand relatively high temperatures, mostly around 70 ℃. Because the HDD is a mechanical hard disk, the temperature change is relatively slow, the time interval can be larger, generally more than 30 seconds when the fan is used for regulating the speed by using the hard disk temperature of the HDD. The SSD is a solid state disk, the temperature of a chip of the SSD changes rapidly, the temperature of the SSD is used for fan speed regulation, and the time interval is relatively small and is generally within 15 seconds. That is, the two hard disks have completely different temperature characteristics, and thus require widely different temperature control strategies.
For the temperature control method of the mixed flash configuration, on one hand, the relatively independent fans and the relatively independent temperature control strategies are considered to be used for respectively dissipating heat of two different hard disks. However, in such a heat dissipation method, the flow speed, temperature, and flow direction of the airflow in the chassis are all uncontrollably changed due to different rotation speeds of the fans, and even turbulence, convection, and the like may occur in the chassis, thereby causing unpredictable damage to the components in the chassis. Therefore, even if the hybrid flash configuration or the hybrid hard disk configuration is adopted, a uniform temperature control strategy is adopted during temperature control, and uniform speed regulation is performed on the air cooling system to perform heat dissipation control of the hard disk while ensuring the safety of elements in the chassis.
Therefore, the mainstream practice in the field is to perform temperature control according to a more severe standard, for example, setting the temperature acquisition time to be 15 seconds, setting the overtemperature threshold to be 60 ℃, and performing fan speed regulation by using the same set of temperature specific curve to ensure that neither the HDD nor the SSD is overtemperature. However, there is still a drawback that in order to keep the operating temperature of the SSD at a low level, for example below 60 ℃, the fan needs to be kept at an ultra-high rotational speed all the time, which may result in very noisy devices operating and poor user experience.
Therefore, it is necessary to provide an optimized temperature control method for a hybrid hard disk, which performs targeted temperature control on the hard disk, reduces the fan noise of the device operation to the maximum extent on the premise of ensuring heat dissipation, and improves the user experience.

Detailed Description
While the present invention may be embodied in various forms, there is shown in the drawings and will hereinafter be described some exemplary and non-limiting embodiments, with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated.
Fig. 1 shows a schematic block diagram of an embodiment of a hybrid hard disk temperature control method according to the present invention. In the embodiment shown in the figure, the method comprises at least the following steps:
s1: setting a first speed regulation strategy according to the temperature characteristic curve of the HDD hard disk, and setting a second speed regulation strategy according to the temperature characteristic curve of the SSD hard disk;
s2, reading the first temperature of the HDD hard disk at intervals of a first time interval, determining a first speed regulating value for the first temperature based on a first speed regulating strategy, and recording the first speed regulating value in a first bit of a speed regulating table;
s3, reading the second temperature of the SSD hard disk at intervals of a second time interval, determining a second speed regulating value for the second temperature based on a second speed regulating strategy, and recording the second speed regulating value in a second bit of the speed regulating table;
s4: the odometer is monitored and in response to a change in a value in the odometer, the first and second values are compared, and the greater of the two is used to control the speed of the fan.
Firstly, the method of the invention is based on that different speed regulation strategies are made for two hard disks with pertinence due to different temperature characteristics of the two hard disks, namely step S1 sets a first speed regulation strategy aiming at the HDD according to the temperature characteristic curve of the HDD, and sets a second speed regulation strategy aiming at the SSD according to the temperature characteristic curve of the SSD. The subsequent steps are judged and executed based on the two speed governing strategies made in step S1.
In order to determine the actually required heat dissipation strength in the operation of the server, based on different characteristics of the two hard disks, the system respectively reads the temperatures of the HDD and the SSD hard disk and determines the corresponding required speed regulation value, that is, step S2 reads the first temperature of the HDD hard disk at a first time interval, determines the first speed regulation value for the first temperature based on the first speed regulation policy, and records the first speed regulation value in a first bit of the speed regulation table, and step S3 reads the second temperature of the SSD hard disk at a second time interval, determines the second speed regulation value for the second temperature based on the second speed regulation policy, and records the second speed regulation value in a second bit of the speed regulation table. Since the two hard disks have different usage conditions and different temperature characteristics during system operation, different first and second time intervals are preferably selected in steps S2 and S3, and the first temperature of the HDD hard disk and the second temperature of the SSD hard disk are different in normal conditions, so that the first and second throttling values determined based on the respective throttling strategies are different, and recording the first and second throttling values in the throttling table is also performed asynchronously.
In order to determine the final speed regulation control signal by comprehensively considering the requirements of the two hard disks, a speed regulation meter needs to be monitored, and when the value in the speed regulation meter changes, the step S4 compares the values of the first bit and the second bit, and the larger of the two is used for controlling the rotating speed of the fan. When the server is started, the speedometer is empty, or preferably corresponding default values are set for the first position and the second position, for example, both the first position and the second position are 0, and at the moment, the fan does not rotate, because the temperature of the hard disk is relatively low when the server is just started, the fan does not need to be started for heat dissipation. Along with the operation of server, the temperature of hard disk rises, and when the temperature reached certain degree, need open the fan and carry out the forced air cooling heat dissipation to the hard disk in order to ensure that the hard disk can not overtemperature, the safety of protection hard disk. At this time, the steps S2 and S3 record the corresponding first and second speed-regulating values in the speedometer, that is, the values in the speedometer are changed, so the step S4 compares the values of the first and second bits in the speedometer to control the rotation speed of the fan with the larger value. In addition, as the server continues to operate, when the first and second speed-regulating values required change due to the temperature fluctuation of the hard disk caused by various reasons, step S4 further compares the values of the first and second bits in the speed-regulating table, and performs the rotation speed control of the fan with the larger one. It should be noted that, if the first throttle value and the second throttle value are changed, but the larger value of the first throttle value and the second throttle value is kept unchanged, even if the first value and the second value in the throttle table are further compared in step S4, the larger value is unchanged, so that the regulation and control of the rotation speed of the fan is kept unchanged.
Further embodiments of the present invention will be described below, it being noted that the numbering of the steps mentioned therein is used only for the convenience of unambiguously indicating the step without any particular indication, and does not limit the order of the steps described.
In some embodiments of the hybrid hard disk temperature control method of the present invention, the first speed regulation strategy is configured to determine a correspondence between the temperature and the speed regulation value according to a temperature characteristic curve of the HDD hard disk, and increase the first speed regulation value in response to the HDD hard disk temperature exceeding a first threshold; the second speed regulation strategy is configured to determine a corresponding relation between the temperature and the speed regulation value according to the temperature characteristic curve of the SSD hard disk, and to respond that the temperature of the SSD hard disk exceeds a second threshold value, and to increase the second speed regulation value.
The operating temperature that HDD hard disks can withstand is generally lower, and HDD mechanical hard disks, the temperature variation is relatively slow. The SSD solid state disk can withstand relatively high temperature, and the temperature of the chip thereof changes rapidly. Therefore, the first speed regulation strategy of step S11 is configured to determine a correspondence between the temperature and the speed regulation value according to the temperature characteristic curve of the HDD hard disk, and increase the first speed regulation value in response to the HDD hard disk temperature exceeding the first threshold. Meanwhile, step S12 determines a correspondence between the temperature and the speed regulation value according to the temperature characteristic curve of the SSD hard disk, and increases the second speed regulation value in response to the SSD hard disk temperature exceeding the second threshold value.
In some embodiments of the method for controlling temperature of a hybrid hard disk of the present invention, the first threshold is smaller than the second threshold. Generally, most HDD hard disks can withstand operating temperatures below 60 ℃, while SSD solid state disks can withstand temperatures of about 70 ℃. Therefore, the first threshold is set smaller than the second threshold, and the first threshold is preferably 60 ℃ and the second threshold is preferably 70 ℃.
In one or more embodiments of the method for controlling temperature of a hybrid hard disk of the present invention, the first time interval is greater than the second time interval. Because the temperature of the mechanical hard disk of the HDD changes relatively slowly, the time interval can be larger, and is usually more than 30 seconds when the temperature of the hard disk of the HDD is used for regulating the speed of the fan. The temperature of the chip of the SSD solid state disk changes rapidly, the temperature of the SSD solid state disk is used for fan speed regulation, and the time interval is relatively small and is generally within 15 seconds. Therefore, the first time interval is set to be greater than the second time interval, wherein the first time interval is preferably 30 seconds and the second time interval is preferably 15 seconds. It should be noted that, on the premise of ensuring the heat dissipation effect, the first time interval and the second time interval may be increased correspondingly to reduce the frequency of the change of the fan speed.
In several embodiments of the method for controlling temperature of a hybrid hard disk of the present invention, the step S4 monitoring the odometer, and in response to a value in the odometer changing, comparing the values of the first bit and the second bit, and controlling the rotation speed of the fan with the greater of the two further comprises: and the PWM signal is adopted to control the rotating speed of the fan. In a preferred embodiment, a PWM (Pulse Width Modulation) signal is used to regulate the rotation speed of the fan, so that accurate control of the fan with sufficiently high accuracy can be achieved.
In a further embodiment of the method for controlling temperature of a hybrid hard disk according to the present invention, the first and second tuning values are corresponding duty ratios. In these embodiments, since the fan is controlled in rotation speed by the PWM signal, the first and second speed regulation values determined according to the read temperature in steps S2 and S3 are duty values of the corresponding PWM signal. The duty ratio value is recorded in a speed regulation meter for comprehensive evaluation, and the actually adopted PWM signal duty ratio is finally determined, so that the rotating speed of the fan is regulated and controlled.
On the other hand, the invention also provides a temperature control device for the hybrid hard disk, which comprises: at least one processor; and a memory storing program code executable by the processor, the program code, when executed by the processor, performing the steps of:
s1: setting a first speed regulation strategy according to the temperature characteristic curve of the HDD hard disk, and setting a second speed regulation strategy according to the temperature characteristic curve of the SSD hard disk;
s2, reading the first temperature of the HDD hard disk at intervals of a first time interval, determining a first speed regulating value for the first temperature based on a first speed regulating strategy, and recording the first speed regulating value in a first bit of a speed regulating table;
s3, reading the second temperature of the SSD hard disk at intervals of a second time interval, determining a second speed regulating value for the second temperature based on a second speed regulating strategy, and recording the second speed regulating value in a second bit of the speed regulating table;
s4: the odometer is monitored and in response to a change in a value in the odometer, the first and second values are compared, and the greater of the two is used to control the speed of the fan.
