Detailed Description
The core of the application is to provide a method for identifying equipment connected with the hard disk backboard, which can realize that the CPLD automatically identifies whether the hard disk backboard is connected with the CPU or the Tri-mode card, and a dial switch is not required to be arranged, so that the production and maintenance efficiency can be improved, and the labor investment can be saved. Another core of the present application is to provide an apparatus, a system, and a computer-readable storage medium for identifying a device connected to a hard disk backplane, which all have the above technical effects.
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of 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 apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 2, fig. 2 is a flowchart of a method for identifying a device connected to a hard disk back plate according to an embodiment of the present application, and referring to fig. 2, the method includes:
s101: receiving a signal sent by equipment currently connected with a hard disk backboard, and analyzing the signal;
s102: when the signals are the first type of signals, determining that the equipment currently connected with the hard disk backboard is a Tri-mode card;
s103: and when the signal is the second type signal, determining that the equipment currently connected with the hard disk backboard is a CPU.
Specifically, referring to fig. 3, when the hard disk back plate is connected to the CPU, the high-speed signal of the CPU is transmitted to the hard disk interface of the hard disk back plate through the high-speed connector of the hard disk back plate, the motherboard sideband signal is transmitted to the CPLD (Complex Programmable Logic Device ) through the high-speed connector, and the VPP signal of the CPU is transmitted to the CPLD through the VPP connector. Referring to fig. 4, when the hard disk back plate is connected to the Tri-mode card, the high-speed signal and the VPP signal of the Tri-mode card are respectively transmitted to the hard disk interface and the CPLD of the hard disk back plate through the high-speed connector. The VPP signal is a signal for notifying the CPLD of lighting, and includes a VPP SCL signal and a VPP SDA signal.
In order to enable the CPLD to automatically identify whether the device currently connected with the hard disk backboard is a CPU or a Tri-mode card, the method and the device customize the types of signals transmitted to the CPLD by the CPU and the Tri-mode card through the high-speed connector on the basis of the hardware design, firmware upgrade is carried out on the CPLD, and firmware upgrade is carried out on at least one of the Tri-mode card and the CPU, so that the type of signals transmitted to the CPLD by the Tri-mode card through the high-speed connector is a first type; the type of signal that causes the CPU to pass through the high-speed connector to the CPLD is the second type; the first type is different from the second type; the CPLD is enabled to identify whether the device currently connected with the hard disk backboard is a CPU or a Tri-mode card by analyzing the type of the received signal.
In a specific embodiment, the first type of signal is a square wave signal. The second type of signal is a single level state level signal.
Specifically, in this embodiment, a first type signal representing that the device to which the hard disk back plate is currently connected is a Tri-mode card is defined as a square wave signal, and a second type signal representing that the device to which the hard disk back plate is currently connected is a CPU is defined as a level signal in a single level state. And carrying out firmware upgrade on the CPLD and the Tri-mode card, and maintaining the original configuration by the CPU.
If the device currently connected to the hard disk backboard is a Tri-mode card, the Tri-mode card outputs the VPP SCL signal in the form of square wave through the high-speed connector, and the CPLD can determine that the device currently connected to the hard disk backboard is the Tri-mode card after receiving the square wave signal.
If the device currently connected to the hard disk back plate is a CPU, the VPP signal is multiplexed as a main board sideband signal, and referring to fig. 5, the main board sideband signal 1 and the main board sideband signal 2 are level signals in a single level state. The single-level signal is a level signal in a high level state or a level signal in a low level state.
Taking a single level state as an example, specifically, a low level signal, if the device currently connected to the hard disk back plate is a CPU, the CPU transmits a continuous low level signal to the motherboard sideband signal 1 of the CPLD through the high-speed connector, and the CPLD detects the continuous low level signal, but does not detect a square wave signal, so that the CPLD can determine that the device currently connected to the hard disk back plate is the CPU.
After the CPLD judges that the device currently connected with the hard disk backboard is the CPU, the CPLD analyzes the VPP signal output by the VPP connector, so that the hard disk lighting information is obtained.
It is understood that the example in which the first type of signal is a square wave signal and the second type of signal is a level signal in a single level state is only one specific implementation provided in the present application. The first type of signal may be a square wave signal, a sawtooth wave signal, a level signal in a single level state, or the like. The second type of signal may be a single level signal, or may be a square wave signal, a sawtooth signal, or the like. As long as the types of the first type signal and the second type signal are different, the specific type of the device currently connected with the hard disk backboard can be identified based on the types of the first type signal and the second type signal, and the differential setting can be performed by those skilled in the art.
Further, on the basis of the above embodiment, as a specific implementation manner, the method further includes: and when the equipment currently connected with the hard disk backboard is determined to be a Tri-mode card, sending a feedback signal to the Tri-mode card, so that the Tri-mode card sets a target zone bit in a target register to be a first value representing that handshake is successful.
Specifically, in this embodiment, a handshake mechanism is introduced between the Tri-mode card and the CPLD, and before the hard disk back plate works normally, the Tri-mode card and the CPLD handshake via VPP signals. When the CPLD receives the square wave signal sent by the Tri-mode card and determines that the equipment currently connected with the hard disk backboard is the Tri-mode card, the CPLD sends a feedback signal to the Tri-mode card, and the CPLD responds to the feedback signal to enable the Tri-mode card to set a target flag bit in a target register as a first numerical value representing that handshake is successful. After receiving the response, the Tri-mode card sets the target flag bit to a first value, enters a normal working state, and outputs a VPP signal to the CPLD so as to transmit the hard disk lighting information to the CPLD.
Referring to fig. 6, the manner in which the CPLD sends the feedback signal to the Tri-mode card may be that the CPLD pulls the VPP SDA signal low.
Namely, the Tri-mode sends a VPP SCL signal in a square wave form to the CPLD, the CPLD receives the square wave signal sent by the Tri-mode card, and after determining that the device currently connected with the hard disk backboard is the Tri-mode card, the CPLD pulls down the VPP SAD signal, and returns. And after the Tri-mode detects that the VPP SDA signal is pulled down, the target flag bit in the target register is set to a first value, for example, set to 1, which indicates that the handshake is successful.
Further, on the basis of the above embodiment, as a specific implementation manner, the method further includes:
reading a firmware version of the CPLD and a firmware version of the Tri-mode card;
and when the CPLD is the updated firmware and the Tri-mode card is the non-updated firmware, reporting errors.
Specifically, the CPLD realizes that the device for automatically identifying the connection of the hard board and the backboard provided by the application is based on that both the Tri-mode card and the CPLD are upgraded, if the Tri-mode card is not upgraded and the CPLD is upgraded, the un-upgraded Tri-mode may not output square wave signals, but may continuously output low-level signals, thereby possibly causing that the hard board and the backboard are actually connected as the Tri-mode card, and the hard board and the backboard are erroneously judged as being connected as the CPU.
When the device is started, the firmware versions of the Tri-mode card and the CPLD can be read by the BMC (Baseboard Manager Controller, baseboard management controller) through an I2C (Inter-Integrated Circuit, a serial bus) bus. If CPLD has been upgraded and the Tri-mode card has not been upgraded, reporting errors in the system to remind the user to upgrade the Tri-mode firmware, thereby ensuring the normal operation of the server.
Except for the case that the CPLD is upgraded and the Tri-mode card is not upgraded, the server can work normally in other cases. If the Tri-mode card is upgraded and the CPLD is not upgraded, although the un-upgraded CPLD cannot automatically identify the equipment connected with the hard disk backboard by adopting the scheme provided by the application, the square wave output by the upgraded Tri-mode cannot influence the un-upgraded CPLD, and the server can work normally. And the CPLD that is not upgraded at this time can learn the device connected to the hard disk back plate in a conventional manner.
If the Tri-mode card is not upgraded and the CPLD is not upgraded, the un-upgraded Tri-mode does not output square waves, but adopts a traditional signal output mode, the CPLD cannot automatically identify the equipment connected with the hard disk backboard by adopting the scheme provided by the application, but the server can work normally. And at this time, the device connected to the hard disk back plate can be known by the non-upgraded CPLD in a conventional manner.
Further, on the basis of the above embodiment, as a specific implementation manner, the method further includes:
reading the target zone bit in the target register;
and when the target flag bit is a second value representing handshake failure and the CPLD is the upgraded firmware, recording a log and reporting errors.
Specifically, if the Tri-mode card is updated and the CPLD is not updated, during the handshake process between the Tri-mode card and the CPLD, the Tri-mode card sends a square wave signal but does not receive a response from the CPLD, and at this time, the Tri-mode card marks a target flag bit in the target register as a second value, for example, 0, for marking the handshake failure, and normally outputs the VPP signal. If the Tri-mode card is not upgraded and the CPLD is upgraded, the Tri-mode card does not output square wave signals and does not receive response of the CPLD, and the Tri-mode card also records a target flag bit in a target register as a second value for marking handshake failure at the moment, and normally outputs VPP signals. On the basis of reading the firmware version of the CPLD and reading the target flag bit of the target register of the Tri-mode card, when the CPLD is judged to be updated and the Tri-mode card does not receive a response, the BMC considers that handshake fails, and at the moment, the BMC records a log and reports errors. The CPLD is updated and the Tri-mode card does not receive the response, generally because the Tri-mode card is not updated, the Tri-mode card does not output square waves and does not receive the response of the CPLD, and therefore, the error reporting can also play a role in reminding a user of updating the Tri-mode.
In summary, the method for identifying a device connected to a hard disk provided by the present application includes: receiving a signal sent by equipment currently connected with a hard disk backboard, and analyzing the signal; when the signals are the first type of signals, determining that the equipment currently connected with the hard disk backboard is a Tri-mode card; and when the signal is the second type signal, determining that the equipment currently connected with the hard disk backboard is a CPU. Therefore, according to the method for identifying the equipment connected with the hard disk backboard, corresponding signal types are defined for the CPU and the Tri-mode card, after the CPLD receives the signals sent by the equipment currently connected with the hard disk backboard, whether the equipment currently connected with the hard disk backboard is the CPU or the Tri-mode card can be automatically identified by analyzing the types of the received signals, a dial switch is not required to be set, and the dial switch is not required to be manually dialed, so that the production and maintenance efficiency can be greatly improved, and the labor investment is saved.
The application also provides a device for identifying the equipment connected with the hard disk backboard, and the device can be referred to in a mutual correspondence manner with the method. Referring to fig. 7, fig. 7 is a schematic diagram of an apparatus for identifying a device connected to a hard disk back plate according to an embodiment of the present application, and in combination with fig. 7, the apparatus includes:
the analysis module 10 is used for receiving signals sent by equipment currently connected with the hard disk backboard and analyzing the signals;
the first determining module 20 is configured to determine that the device currently connected to the hard disk back plate is a Tri-mode card when the signal is a first type signal;
and the second determining module 30 is configured to determine that the device currently connected to the hard disk back plate is a CPU when the signal is a second type signal.
Specifically, in order to enable the CPLD to automatically identify whether the device currently connected to the hard disk back plate is a CPU or a Tri-mode card, the method and the device enable the CPLD to customize the types of signals transmitted to the CPLD by the CPU and the Tri-mode card through the high-speed connector, upgrade the CPLD and the Tri-mode card, enable the type of signals transmitted to the CPLD by the Tri-mode card through the high-speed connector to be a first type, enable the type of signals transmitted to the CPLD by the CPU to be a second type, and enable the CPLD to identify whether the device currently connected to the hard disk back plate is the CPU or the Tri-mode card by analyzing the types of the received signals.
The signal received by the CPLD is firstly analyzed by the analysis module 10, and if the signal is a first type signal, the first determination module 20 determines that the device currently connected with the hard disk backboard is a Tri-mode card; if the signal is of the second type, the second determining module 30 determines that the device to which the hard disk back plate is currently connected is a CPU.
On the basis of the above embodiment, optionally, the first type signal is a square wave signal.
Alternatively, the second type of signal is a single level state level signal.
Specifically, if the device currently connected to the hard disk back plate is a Tri-mode card, the Tri-mode card outputs the VPP SCL signal in the form of a square wave through the high-speed connector, and after the CPLD receives the square wave signal, the first determining module 20 may determine that the device currently connected to the hard disk back plate is the Tri-mode card.
If the device to which the hard disk back plate is currently connected is a CPU, the VPP signal is multiplexed as a main board sideband signal, and the main board sideband signal transmitted to the CPLD by the CPU through the high-speed connector is a level signal that is continuously in a certain state, for example, is continuously a low level signal, and the CPLD detects the continuous low level signal, but does not detect the square wave signal, so the second determining module 30 may determine that the device to which the hard disk back plate is currently connected is a CPU.
On the basis of the above embodiment, optionally, the method further includes:
and the feedback module is used for sending a feedback signal to the Tri-mode card when the equipment currently connected with the hard disk backboard is determined to be the Tri-mode card, so that the Tri-mode card sets a target zone bit in a target register to be a first value representing that handshake is successful.
On the basis of the above embodiment, optionally, the feedback module is specifically configured to:
the VPP SAD signal is pulled low.
Specifically, in this embodiment, a handshake mechanism is introduced between the Tri-mode card and the CPLD, and before the hard disk back plate works normally, the Tri-mode card and the CPLD handshake via VPP signals. When the CPLD receives the square wave signal sent by the Tri-mode card, the first determining module 20 determines that the device currently connected to the hard disk back plate is the Tri-mode card, and the CPLD pulls the VPP SAD signal low, and in response, causes the Tri-mode card to set the target flag bit in the target register to a first value representing that handshake is successful. After receiving the response, the Tri-mode card sets the target flag bit to a first value, enters a normal working state, and outputs a VPP signal to the CPLD so as to transmit the hard disk lighting information to the CPLD.
On the basis of the above embodiment, optionally, the method further includes:
the first reading module is used for reading the firmware version of the CPLD and the firmware version of the Tri-mode card;
and the first error reporting module is used for reporting errors when the CPLD is the updated firmware and the Tri-mode card is the non-updated firmware.
Specifically, in order to avoid erroneous judgment and ensure that the server works normally, the embodiment introduces a firmware detection mechanism. When the device is started, the firmware versions of the Tri-mode card and the CPLD can be read by the first reading module. If CPLD has been upgraded and the Tri-mode card has not been upgraded, reporting errors in the system by the first error reporting module to remind the user to upgrade the Tri-mode firmware, thereby ensuring the normal operation of the server.
Except for the case that the CPLD is upgraded and the Tri-mode card is not upgraded, the server can work normally in other cases. If the Tri-mode card is upgraded and the CPLD is not upgraded, although the un-upgraded CPLD cannot automatically identify the equipment connected with the hard disk backboard by adopting the scheme provided by the application, the square wave output by the upgraded Tri-mode cannot influence the un-upgraded CPLD, and the server can work normally. And at this time, the device connected to the hard disk back plate can be known by the non-upgraded CPLD in a conventional manner.
If the Tri-mode card is not upgraded and the CPLD is not upgraded, the un-upgraded Tri-mode does not output square waves, but adopts a traditional signal output mode, the CPLD cannot automatically identify the equipment connected with the hard disk backboard by adopting the scheme provided by the application, but the server can work normally. And at this time, the device connected to the hard disk back plate can be known by the non-upgraded CPLD in a conventional manner.
On the basis of the above embodiment, optionally, the method further includes:
the second reading module is used for reading the target zone bit in the target register;
and the second error reporting module is used for recording a log and reporting errors when the target zone bit is a second numerical value representing handshake failure and the CPLD is the upgraded firmware.
Specifically, if the Tri-mode card is upgraded and the CPLD is not upgraded, during the handshake between the Tri-mode card and the CPLD, the Tri-mode card sends a square wave signal but does not receive a response from the CPLD, at this time, the Tri-mode card marks a target flag bit in the target register as a second value, for example, 0, for marking the handshake failure, and normally outputs the VPP signal. If the Tri-mode card is not upgraded and the CPLD is upgraded, the Tri-mode card does not output square wave signals and does not receive response of the CPLD, and the Tri-mode card also records a target flag bit in a target register as a second value for marking handshake failure at the moment, and normally outputs VPP signals. The first reading module reads the firmware version of the CPLD and the second reading module reads the target flag bit of the target register of the Tri-mode card, and when the CPLD is judged to be upgraded and the Tri-mode does not receive a response, the handshake is considered to be failed, and at the moment, the second error reporting module records a log and reports errors.
According to the device for identifying the equipment connected with the hard disk backboard, corresponding signal types are defined for the CPU and the Tri-mode card, after the CPLD receives the signals sent by the equipment currently connected with the hard disk backboard, whether the equipment currently connected with the hard disk backboard is the CPU or the Tri-mode card can be automatically identified by analyzing the types of the received signals, a dial switch is not required to be arranged, and the dial switch is not required to be manually dialed, so that the production and maintenance efficiency can be greatly improved, and the labor investment can be saved.
The present application also provides an apparatus for identifying an apparatus for hard disk backplane connection, the apparatus comprising a memory 1 and a processor 2, as shown with reference to fig. 8.
A memory 1 for storing a computer program;
a processor 2 for executing a computer program to perform the steps of:
