Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the related art, two methods for opening the VMD function of the NVMe interface exist, one method is to enter a BIOS interface to manually open an option, but the operation is inconvenient and the efficiency is low; the other is that some specific GPIOs are connected to the NVMe interface on hardware, and then the VMD is automatically opened through the change of GPIO level caused by accessing the NVMe hard disk, however, the hardware circuit increases the complexity of design and increases the hardware cost. Based on the above technical problem, this embodiment provides a VMD control method, which can improve the control efficiency of the on/off state of the VMD function and save the cost, specifically referring to fig. 1, where fig. 1 is a flowchart of the VMD control method provided in this embodiment of the present application, and specifically includes:
s101, detecting and judging the connection state of the NVMe interface.
Further, before detecting and determining the connection state of the NVMe interface, the method further includes: setting a preset mode of the on-off state of the VMD function corresponding to the NVMe interface in a BIOS program; the preset mode comprises an automatic mode, an on mode and an off mode. And the automatic state is closed (Disabled) by default when the hard disk is not accessed, then the BIOS detects whether the link state of the NVMe interface is linked, and if the link state is linked, the BIOS switches the automatic (Auto) state to the open mode to open the VMD function of the NVMe interface. The method has two main advantages, one is that an additional hardware circuit is not needed to be added for opening the VMD function when the server mainboard is designed, the other is that maintenance personnel do not need to enter the BIOS interface to manually open the VMD function when the NVMe hard disk is subjected to RAID array, the NVMe hard disk is only needed to be accessed, the BIOS can be automatically opened in the starting process, the complexity of RAID array operation on the NVMe hard disk is greatly reduced, and the maintenance efficiency of the server is improved.
The BIOS chip is stored with a BIOS program, a preset mode is set in the BIOS program aiming at the switch loading of the function of the VMD corresponding to the NVMe interface, the preset mode comprises an automatic (Auto) mode, an opening (Enabled) mode and a closing (Disabled) mode, and the automatic mode is in a closing state by default when the NVMe is not accessed. Through setting different modes, a user can set the modes automatically, automatic control is achieved, and applicability is improved.
Detecting and judging the connection state of the NVMe interface in real time, specifically, when the NVMe interface is accessed to the NVMe, the connection state is connected; when the NVMe interface is not accessed into the NVMe, the NVMe interface is not connected in the connection state. The detection and determination period is not limited in this embodiment, and may be every 5min or 10min or other periods, and the user may perform the user-defined setting as long as the purpose of this embodiment can be achieved.
And S102, when the connection state is connected, setting the switch state of the VMD function corresponding to the NVMe interface to be an on state so as to open the VMD function.
When the connection state is connected, there are two cases, before the connection state, the connection state is connected or the connection state is changed from unconnected to connected, and at this time, it is ensured that the switch state of the VMD function corresponding to the NVMe interface is set to the on state, so as to turn on the VMD function.
Further, when the connection state is connected, setting the switch state of the VMD function corresponding to the NVMe interface to an on state, so as to turn on the VMD function, including:
when the connection state is connected, if the switch state of the VMD function corresponding to the NVMe interface is an off state, the VMD function is switched to the on state so as to turn on the VMD function.
Specifically, the connection state is connected, but the switch state of the VMD function corresponding to the NVMe interface is an off state, which may be due to a system error or that the VMD function is not connected in the previous connection state, and therefore, the VMD is switched to the on state at this time so as to be turned on, which may be ended, and then step S101 is executed again after the preset period.
And S103, when the connection state is not connected, setting the switch state to be an off state so as to close the VMD function.
When the connection state is unconnected, there are two cases, that is, the connection state is unconnected before the connection state, or the connection state is changed from connected to unconnected, and at this time, it is ensured that the on-off state of the VMD function corresponding to the NVMe interface is set to the off state, so as to turn off the VMD. May be finished and then the step S101 is performed again after a preset period.
Further, when the connection state is not connected, the switch state is set to the off state so as to turn off the VMD function, including:
when the connection state is not connected, if the switch state is on, the switch is switched to off state.
Specifically, the connection state is not connected, but the on-off state of the VMD function corresponding to the NVMe interface is an on state, which may be due to a system error or connection in the previous connection state, and therefore, the VMD is switched to an off state at this time so as to be turned off.
Further, the method also comprises the following steps: and displaying the switch state on a display interface. Therefore, a user can conveniently acquire the switch state in real time.
Based on the above technical scheme, this embodiment detects and judges the connection state of NVMe interface through the BIOS chip in real time, according to the automatic on-off state of the VMD function that control NVMe interface corresponds of connection state, has avoided the problem that the control efficiency that needs manual to cause among the correlation technique is low and increase the high cost that hardware caused, has improved the control efficiency of the on-off state of VMD function, practices thrift the cost.
Based on the foregoing embodiment, this embodiment provides a VMD control method, which implements operation validity and improves security by determining whether NVMe connected to an NVMe interface is valid NVMe, specifically referring to fig. 2, where fig. 2 is a flowchart of another VMD control method provided in this embodiment of the application, and includes:
s201, judging whether the NVMe connected with the NVMe interface is legal NVMe or not.
The purpose of this step is to judge the legitimacy of NVMe, and only legal NVMe can detect and judge the connection state after connecting the NVMe interface, and then control the switch of VMD function. Judging the valid NVMe may be to determine whether the NVMe is the valid NVMe by IP, tag, NVMe access time, and the like of the NVMe. For example, whether the IP of the NVMe connected to the NVMe interface is the IP of the legal NVMe is determined, specifically, the comparison may be performed according to each legal IP in the preset legal IP table, and if the comparison is successful, the comparison is the legal IP of the legal NVMe.
Further, determining whether the NVMe interfaced with the NVMe is a legitimate NVMe includes: matching the NVMe label with a label in a preset legal library to obtain a matching result; and determining whether the NVMe is legal NVMe according to the matching result. Specifically, the label of the NVMe is a, the labels in the preset legal library include a1, a2, a3, a4, a5 and a6, and if matching between a and the label a1 in the preset legal library is successful, the NVMe is determined to be legal NVMe; and if the a is not successfully matched with the label in the preset legal library, determining that the NVMe is illegal NVMe. Therefore, the safety can be improved by judging whether the NVMe connected with the NVMe interface is legal or not.
And S202, if the NVMe is legal, detecting and judging the connection state of the NVMe interface.
And S203, when the connection state is connected, setting the switch state of the VMD function corresponding to the NVMe interface to be in an on state so as to open the VMD function.
