Description
Technical Field
The invention relates to computer hard disk management, in particular to a system supporting hard disk hot plug and an implementation method thereof.
Background
The history of hot plug technology of computer hardware has been long, and especially since the Windows system supports hot plug technology, the application of hot plug technology is more common. At present, there are many computer hardware that can support hot plug technology, such as network card, mobile hard disk, and other various mobile storage devices, such as USB. For a hard disk, only an SCSI hard disk to which a high-end technology of the hard disk is applied supports a hot plug technology, and other low-end hard disks cannot support the hot plug technology. The hot plug technology of the hard disk is very useful from the aspect of practical application because the hard disk can be plugged in or unplugged from the hard disk without the server shutdown, which is very practical for the server system needing 24 hours of shutdown.
However, the price of the SCSI hard disk is still high due to its high-end technology, and generally, the price of the SCSI hard disk is more than 80% higher than that of a Parallel-ATA hard disk of the same capacity, so if the SCSI hard disk is purchased in its entirety to apply the hot-plug technology, the cost of the system becomes very high.
If a method for realizing hot plug of a Parallel-ATA hard disk can be found and a system for allowing the hot plug of the hard disk is provided, a large amount of money can be saved for a low-end user.
Disclosure of Invention
In order to solve the problem that the cost of a SCSI hard disk capable of realizing hot plugging is too high, but a Parallel-ATA hard disk with low cost cannot be subjected to hot plugging, the inventor provides a method capable of performing hot plugging on a Parallel ATA hard disk.
The main reason why the conventional ATA hard disk cannot be hot-plugged is that the surge current flowing through the hard disk will break down the hard disk during hot-plugging, resulting in damage to the hard disk and data loss.
According to an aspect of the present invention, a system for supporting hard disk hot plug is provided, which at least includes a processor, a system hard disk, a system power supply, a backplane slot for connecting the hard disk, a first cooling fan, and a current limiting control circuit, which is connected in series between the system power supply and the backplane slot, for eliminating surge current generated at the moment of hot plug into the hard disk, and the processor controls the voltage of the hot-plugged hard disk so that the hard disk can operate normally.
According to another aspect of the present invention, on the basis of the system for supporting hard disk hot plug-in, there is also provided a system for supporting hard disk hot plug-out, further comprising a monitoring chip, which is respectively connected to the voltage monitoring circuit and the temperature detecting circuit, and is used for detecting data of voltage and temperature; the voltage limiting control circuit at least comprises a voltage limiting resistor which is connected in series between the system power supply and the back plate slot and is used for bearing voltage in the process of hot drawing out the hard disk; the hard disk hot plug management software is operated by the processor, is communicated with an operating system which is operated originally on the system, and is used for controlling the voltage and data operation safety of the hot-pulled hard disk; and the processor is connected with the monitoring chip and used for controlling the hot drawing process.
The hard disk hot plug management software controls the voltage of the hard disk to be close to zero before the hard disk is hot pulled out, so that the hard disk can be safely pulled out; and the hard disk is also controlled to stop all data operations before hot extraction, so that the data loss is avoided. The hard disk hot plug management software can also control the voltage of the hard disk to reach the working voltage, for example, 5V, and send control information to the control processor after the hard disk is hot-plugged, so that the operating system originally running on the system can identify the hot-plugged hard disk.
The hard disk hot plug management software comprises an interaction module and a control module, wherein the interaction module and the control module are communicated with each other, the interaction module is used for receiving an instruction of a user, sending a processing instruction to the control module and timely feeding back a processing result of the control module to the user, the control module is used for receiving the processing instruction of the interaction module, feeding back the processing result to the interaction module and specifically processing the processing result to enable the hard disk which is requested to be hot-unplugged to stop any data operation, controlling the voltage of a back plate slot in which the hard disk which is requested to be hot-unplugged is lowered to a pressing state which tends to 0, controlling the inserted back plate slot to be electrified to be a normal working voltage after the hard disk is hot-plugged, and informing an operating system allowed by the control processor to identify the hard disk.
In the system for supporting hot plug of the hard disk, the monitoring chip is further connected with a fan rotating speed monitoring circuit for detecting fan data.
In the system for supporting the hot drawing of the hard disk, the monitoring chip detects the voltage and the temperature of the hard disk in real time, and simultaneously, the monitoring chip also detects the fan in real time; or, the monitoring chip selectively detects the voltage and the temperature of the hard disk in real time, or detects the fan in real time.
The monitoring chip completes the real-time detection process through one or more of IPMI protocol, I2C bus and V12C.
The detection chip directly judges the detected results, if any one or more of the results exceed the preset safety range, the detection chip sends request information to the processor, and the processor sends alarm information. Or the monitoring chip sends request information to the processor, the processor sends the request information to the management software, and an interaction module of the management software reminds a user that the hard disk does not have the hot-unplugging condition.
The detection chip can also transmit the detection result to the processor in real time, the processor transmits the data to the control module, and if the control module confirms that any one or more of the detection results exceed a preset safety range, the processor sends alarm information. Or,
the processor controls a buzzer to send out the alarm information. The processor is connected with the buzzer through a bus.
In the system for supporting hard disk hot plug, the voltage limiting control circuit further includes a delay circuit, which makes the voltage limiting resistor short-circuited after a fixed delay.
The system for supporting hard disk hot-plug also comprises at least one second heat dissipation fan.
The preset safe range values of the voltage, the fan and the temperature are set by a user according to the specific environment in which the system operates.
The processor is connected with the voltage control circuit of the backboard slot and sends out instructions to control the voltage value, thereby controlling the voltage of the hard disk which is inserted or pulled out in a hot state.
In the process of hot insertion of the hard disk, surge current can be generated in the circuit at the moment of insertion, and the current-limiting control circuit is arranged between the power supply and the hard disk slot, so that the surge current generated in the circuit can be gathered at the moment of insertion, and the hot-inserted hard disk cannot bear overhigh current and cannot be damaged.
However, due to the existence of the current limiting control circuit, when the hard disk is hot-unplugged, because the load on the current limiting control circuit may be instantaneously eliminated, for example, when the current limiting control circuit is an inductor, a strong self-excitation may be generated by the inductor itself, so that a great interference may be generated on other parts of the circuit of the whole computer, and the whole computer may be unstable. The voltage limiting control circuit connected in series between the system power supply and the hard disk slot can play a role of a current limiting resistor, and a large amount of current is gathered when the hard disk is hot pulled out, so that main voltage is borne, and the hard disk is prevented from being damaged due to overhigh voltage.
The invention can realize the hot plug of the low-cost Parallel-ATA hard disk or other hard disks, thereby saving a large amount of funds for server users. The application of the technology can enable manufacturers applying the technology to effectively seize the server market.

Detailed Description
Referring to fig. 1, one embodiment of the present invention is described. The system comprises a processor 1 and a monitoring chip 2, wherein the processor 1 and the monitoring chip 2 are connected with each other. The monitoring chip 2 is connected with a voltage monitoring circuit, a fan rotating speed monitoring circuit and a temperature monitoring circuit through 3 pins 21 respectively, and the monitoring chip 2 is also connected with an 14.318MHz crystal oscillator chip 61. The monitoring chip 2 monitors the voltage, the fan speed and the temperature in real time through the line connection, further judges whether the equivalence is in a safety range required by hot plugging of the hard disk, and sends a request containing that the voltage or the fan or the temperature is not in the safety range to the processor 1 if the equivalence is not in the safety range. In another embodiment, the monitoring chip 2 is only used to monitor voltage, fan, temperature indicators and transmit the indicators to the processor 1 in real time, and the management software running in the processor determines whether the indicators exceed the safety range, and further responds, for example, displaying a window to prompt the user or making a buzzer continuously sound to prompt the user.
However, those skilled in the art can understand that in a variation similar to the present embodiment, the monitoring chip 2 is connected to the voltage monitoring circuit and the temperature monitoring circuit through only 2 pins 21, that is, the indexes such as the rotation speed of the fan are not detected, which can be implemented when the rotation speed of the fan is not an important consideration.
The voltage, the fan and the temperature that fall within the safe range are subject to the range that the hard disk with the highest environmental requirement can withstand, for example, in this embodiment, the voltage range is 0.5V, the rotation speed of the fan is above 2000 rpm, and the temperature is lower than 50 ℃. However, those skilled in the art can understand that in other embodiments, the safety range may also be adjusted, for example, specific adjustment and control may be performed according to a coefficient of a hard disk, so that dynamic setting may be performed in different operating environments. It can be further understood by those skilled in the art that when the management software determines whether the constant voltage, the fan speed, and the temperature are within the safety range, different safety ranges can be dynamically set, so as to be more accurately suitable for different hard disks, which is not described herein.
Referring to fig. 1, in the present embodiment, the processor 1 further controls the voltage of the backplane slot 4 through a circuit, and the hard disk 3 is connected to the backplane slot 4. Through the control of the processor 1, the voltage of the backplane slot can be gradually reduced until the voltage reaches the safety range, so that the condition of hot-plugging the hard disk is met. When the hard disk is hot-plugged into the backplane slot 4, the backplane slot 4 sends a power-on request to the processor 1, in this embodiment, the processor sends a power-on request to the management software, and the management software controls the processor to gradually restore the voltage of the corresponding backplane slot to a working voltage, for example, 5V, through the control module. In another embodiment, after the backplane socket 4 sends a power-up request to the processor 1, the processor 1 directly controls the voltage of the backplane socket 4 to return to the working voltage.
Referring to fig. 1, the processor 1 is further connected to a fan controller 9, and the fan controller 9 is further connected to two fans (not numbered), and similarly, the processor 1 controls the rotation speed of the fans through the fan controller 9, so that the rotation speed of the fans meets the safety range for hot plugging of the hard disk. In this embodiment, considering that most hard disks to be hot-plugged are devices with relatively large heat generation, two fans are adopted to meet the requirement of heat dissipation. While those skilled in the art will appreciate that in other possible embodiments, more fans may be employed, such as 3 or more. At the same time, however, it is also contemplated that only one fan may be employed and still be controlled by the fan controller 9 in an embodiment similar to that shown in fig. 1, and those skilled in the art will appreciate that in such an embodiment, the system may still be operated.
Referring to fig. 1, the processor 1 is further connected with an 7.3728MHz crystal oscillator chip 62.
Referring to fig. 1, in this embodiment, the processor 1 is further connected to a buzzer 7, and the buzzer is controlled to sound when the voltage, the fan speed or the temperature are not within a safe range. In this embodiment, when the voltage, the fan speed or the temperature are not within the above-mentioned safety range, the system controls the buzzer 7 to generate different buzzes respectively, for example, three long and two short buzzes when the voltage exceeds the safety range, and all the buzzes configured according to the embodiment of the present invention are different from the prompting sound configured by the existing computer system.
Referring to fig. 1, in another embodiment, the processor 1 is not connected to the buzzer 7, and when the voltage, the fan speed or the temperature are not within a safe range, the management software prompts the user not to perform hot plug on the hard disk.
Referring to fig. 1, although not shown in fig. 1, in the embodiment shown in fig. 1, a hard disk hot plug management software, which includes an interaction module and a control module, is run in the processor 1. In an embodiment of the present invention, when a user needs to hot-unplug a hard disk, the interactive module is awakened through a hot key, the interactive module provides a window for the user to operate, that is, a list of all hard disks that the user can hot-unplug is listed in the window, the user selects one or more hard disks, and clicks a "hot-unplug" button, so as to submit a request for hot-unplugging the hard disks through the interactive module. And after receiving the request for hot-unplugging the hard disk, the control module processes the request. In this embodiment, the control module obtains the voltage or the fan speed or the temperature value of the requested hard disk through the processor 1, and further determines whether the requested hard disk is within the safety range, if the requested hard disk is not within the safety range, the control module prompts a user that the relevant hard disk cannot be hot-unplugged at this time through the interaction module, and further adjusts the voltage or the fan speed or the temperature value through the processor 1 until the requested hard disk is within the safety range; if the hard disk is in the safety range, the control module further monitors whether the system writes data into or reads data from the requested hard disk, and if so, the interaction module also prompts a user that the related hard disk cannot be hot-unplugged at the moment until the read-write operation is completed and prompts the user that the hard disk can be hot-unplugged.
In a similar embodiment, when the voltage or the fan speed or the temperature is not within the safety range or the requested hard disk is being read or written, the control module controls the interaction module to display a prompt message of "the system stops the requested hard disk, please wait" or the like until the condition of hot-unplugging the hard disk is met, and the control module displays a prompt message of "the requested hard disk can be hot-unplugged" or the like through the interaction module.
It will be appreciated by those skilled in the art that in one embodiment of the invention, the processor 1 shown in FIG. 1 is a processor other than a central processing unit native to the computer system or other system to which the invention applies, such as a second central processing unit. In another embodiment of the present invention, the processor 1 may be an original central processing unit of a computer system or other systems to which the present invention is applied, in this case, for example, the hard disk hot plug management software may directly read the detection results from the monitoring chip, and if one or more of the detection results exceed the set safety range, it sends an instruction to the processor 1 to control the buzzer 7 to send a prompt sound.
As described in the summary of the invention, during the process of hot-plugging into a hard disk, surge current may be generated in the circuit at the moment of plugging, and thus the plugged hard disk, such as an ATA hard disk, may be damaged. For this reason, in the present embodiment, an effective circuit is specifically designed to eliminate the surge currents. Referring to fig. 2, a current limiting control circuit 52, in this embodiment, an inductor 52, is further disposed between the system power supply 51 and the backplane slot 4 (not shown), and surge current generated at the moment of hot plugging into the hard disk is collected by the inductor 52, so as to ensure that the hot plugged hard disk does not carry too high current and is not damaged.
Referring to fig. 2 again, in this embodiment, due to the existence of the inductor 52, when the hard disk is hot-unplugged, the load on the inductor is instantaneously eliminated, so that the inductor 52 itself generates a strong self-excitation, which generates a large interference to other parts of the circuit of the whole computer, and may cause the whole computer to be unstable. For this reason, referring to fig. 2, a voltage limiting control circuit 53 is connected in series between the system power supply 51 and the backplane socket 4 for limiting voltage, and in this embodiment, the voltage limiting control circuit includes a resistor 53, which gathers a large amount of current when the hard disk is hot-unplugged, so as to carry a main voltage and prevent the hard disk from being damaged due to an excessively high voltage.
It will be understood by those skilled in the art that in the present embodiment, in order to prevent the resistor from consuming too much power and thus not affecting the normal operation of the hard disk, the voltage limiting control circuit 53 is not always connected between the power supply 51 and the hard disk, but the voltage limiting control circuit 53 only functions in the circuit shown in fig. 2 when the hard disk is hot-unplugged. In the present embodiment, a delay circuit and a circuit connected in parallel with the resistor 53 are used to achieve this purpose, and those skilled in the art can understand that such a circuit belongs to a mechanical contact type, and the circuit for short-circuiting the resistor 53 can also be implemented by an electronic contact type circuit, which is not described in detail.
In another embodiment, it will be further understood by those skilled in the art that the current limiting control circuit 52 may be connected to the circuit between the system power supply 51 and the backplane slot 4 only during the hot plug process by the similar method described above, which is not described herein.
It will further be appreciated by those skilled in the art that the above described approach to limiting inrush current can be implemented in a variety of ways, and can be implemented with reference to a number of existing sources. For example, reference may be made to at least the application of input inrush current suppression modules to AC/DC converters (Power supply technology application (ISSN: 0219) -2713), No. 1 of 2004, Ningwu, Mongolian darling, Lixue, Lijun,http://www.china-power.net/psta/dzkw/401/06.htm) And the design of an Inrush Current Limiting Circuit (ICLC) based on a new device STIL (power technology application, 12 th 2004).
Those skilled in the art will understand that, in another embodiment, the current-limiting control circuit (e.g., the inductor 52) and the voltage-limiting control circuit (e.g., the resistor 53) may be always connected to the circuit between the system power supply 51 and the backplane socket 4, that is, the current-limiting control circuit (e.g., the inductor 52) and the voltage-limiting control circuit (e.g., the resistor 53) are directly connected in series between the system power supply 51 and the backplane socket 4 without any other circuit. Such practice does not directly hinder the object of the invention. It will further be appreciated by those skilled in the art that at least the resistor 53 would result in a waste of electrical energy if so done.
Referring to fig. 3, a schematic diagram of hot-plug and hot-unplug of a hard disk before and after applying the present invention is described. Before the invention is applied, when the HDD hard disk is inserted into the back plate, step S102, the hard disk is finally broken down, step S104; after the invention is applied, an inductor is connected in series between the backplane power supply and the backplane slot, step S201, the inductor eliminates the instant surge current, step S203, so that the hot-plugged hard disk can be normally used in the system, step S204.
Referring to fig. 3, before applying the present invention, when the HDD hard disk is pulled out of the backplane, step S301, the entire system is finally unstable, step S304; after the invention is applied, a current-limiting resistor is connected in series at the moment when the load is switched on, and when the capacitive load is charged to a certain degree, the current-limiting resistor is cancelled, step S401, the self-excited current problem generated by the inductor is solved, step S403, so that the hard disk can be normally hot-plugged in the system, and step S404.
Those skilled in the art will understand that the above-mentioned hot-swappable hard disk should be premised on not affecting the permission of the operating system, i.e. theoretically, the system hard disk cannot be hot-swappable. However, this does not indicate that the present invention is not suitable for these system hard disks, and the system running the present invention is completely broken down because the system hard disk, once hot-unplugged, will cause the operating system to fail to operate normally. Therefore, in some embodiments of the present invention, when a user requests to hot-unplug a hard disk through the interaction module, the interaction module directly shields the system hard disk so that the user cannot request the system hard disk.
Although the present invention has been described with reference to the preferred embodiments as described above, the above embodiments are not intended to limit the present invention, and any person skilled in the art should be able to make various changes and modifications in light of the design concept, the detailed description, and the teaching of the embodiments of the present invention, and new contents obtained by such changes and modifications should be covered by the present disclosure.
