Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a frame management apparatus. The core of this embodiment is: frame management device includes: frame body, two at least veneers and at least one fan, the veneer is inserted on the trench of frame body, and the veneer includes: a programmable logic device and a baseboard management controller BMC; the BMC is used for acquiring the temperature of the single board, acquiring a speed regulation value corresponding to the temperature of the single board according to the temperature of the single board and sending the speed regulation value to the programmable logic device of the single board; at least two single boards are divided into a management single board and a managed single board; the programmable logic device of the managed single board is used for sending the speed regulation value of the managed single board to the management single board; the programmable logic device of the management single board is used for receiving the speed regulating numerical values of the single boards and sending the maximum speed regulating numerical value in the speed regulating numerical values of the single boards to the fan, so that the workload of software development and maintenance can be reduced, the hardware cost is reduced, and the fan is prevented from being in a management blank window period. The following describes the details of the frame management device according to this embodiment in detail, and the following description is only provided for ease of understanding and is not necessary to implement this embodiment.
The single boards in the embodiment are all inserted into the slot positions of the machine frame body, and the number of the slot positions on the machine frame body can be the same as or more than that of the single boards. The single board used for machine frame management, namely the slot position where the management single board is inserted, can be connected with the fan, so that when the management single board is inserted into the slot position connected with the fan, the management single board can directly receive signals and perform further processing. That is, when any one board is inserted into the slot connected to the fan, the fan can be directly managed.
As shown in fig. 3, the machine frame management device according to the present embodiment specifically includes: a machine frame body (not shown), a management single board 101, a managed single board 102, a fan 103, a fan 104 and a fan 105. The management board 101 includes a BMC1011 and an EPLD1012, the EPLD1012 is connected to the fan 103, the fan 104, and the fan 105, and the managed board 102 includes a BMC1021 and an EPLD1022. In this embodiment, the number of the single plates is only 2, but the number is not limited to this in practical application. The EPLD in this embodiment is a programmable logic device, and in practical application, the EPLD may be replaced by a single chip or a programmable logic device such as an FPGA. In fig. 3, the number of fans is 3 as an example, but in practical application, the number of fans can be determined according to actual needs, and the embodiment is not particularly limited.
Specifically, the BMC1011 may be understood as a processor unit of the board, and is configured to obtain a board temperature of the management board 101, where the obtained board temperature may be a temperature of a chip, a memory, a hard disk, and other components on the board in practical application. The temperature information can be detected through a temperature sensor arranged on the single board, the speed regulation requirement corresponding to the temperature of the single board is obtained according to the detected temperature information, the speed regulation requirement can comprise a speed regulation numerical value obtained through calculation according to the temperature of the single board, the speed regulation numerical value can be understood as the rotating speed of the fan, the higher the temperature of the single board is, the larger the corresponding rotating speed of the fan is, and therefore the air quantity can be increased to reduce the temperature of the single board. Similarly, the BMC1021 is configured to obtain a board temperature of the managed board 102, and obtain a speed regulation value corresponding to the temperature of the managed board.
Further, the BMC1011 sends the throttle value of the management board 101 to the EPLD1012, the BMC1012 sends the throttle value of the managed board 102 to the EPLD1022, and the EPLD1022 sends the throttle value of the managed board 102 to the EPLD1012 of the management board 101, which may be specifically sent at fixed time intervals.
The EPLD1012 compares the received speed-regulating value of the managed board 102 with the speed-regulating value of the managing board 101, and sends the largest one of the speed-regulating values to the fan 103, the fan 104, and the fan 105. The fan adjusts the rotating speed according to the received speed regulation value so as to meet the cooling requirement of each single plate in the machine frame.
The EPLD1022 sends the throttling value of the managed board 102 to the EPLD1012 of the managing board 101, which may specifically be implemented as follows: since the number of pins of the EPLD is typically several hundred, some of the pins may be edited and defined by programming as an inter-board communication interface that can be used for data transmission, for example, as an I2C interface, an RS232 interface, an SPI interface, and the like. The EPLD1022 may send the throttling value of the managed board 102 to the EPLD1012 of the managing board 101 through the inter-board communication interface defined by the editor.
Further, EPLD1012 sends the maximum one of the throttle values to fan 103, fan 104, and fan 105 by: some pins in the EPLD1012 are defined by programming as I2C interfaces that can be used to transmit control commands to the fans, and the EPLD1012 sends the maximum speed-adjusting value among the speed-adjusting values of the respective boards to the respective fans through the defined I2C interfaces by programming.
In an example, the number of inter-board communication interfaces edited and defined by the EPLD1012 of the management board 101 may be the same as the number of managed boards, and each inter-board communication interface of the EPLD1012 receives speed regulation data sent by a managed board and fills the speed regulation data in a corresponding register to form a value field, for example, field 1 in fig. 3 corresponds to the speed regulation value of the management board 101, and field 2 corresponds to the speed regulation value of the managed board 102. The EPLD1012 compares the two fields, selects the maximum value, and outputs the selected field 2 value to each fan through the I2C interface generated by editing the EPLD1012, for example, the field 2 value is greater than the field 1 value, which is only exemplified by outputting to the fan 105 in fig. 3, but not limited to this in practical application.
The inventor analyzes and obtains that in the process of implementing the invention, in the prior art, speed regulation data are exchanged between single boards through a GE (Gigabit Ethernet,1000M Ethernet) network port, a GE Gigabit Ethernet high-speed line is required, the price is high, and a MAC (media access control) chip and a PHY (physical layer) chip of a 4-port Gigabit Ethernet are used, the cost exceeds 200 th of one single board, so that simple inter-board data are transmitted, and waste is relatively high. And by modifying the BMC on the single board, a communication interaction protocol needs to be customized, so that the cost of software development and maintenance is increased. And because the BMC is a small processor system, the time for the power-on starting process is long, generally tens of seconds, and after the equipment is started, the BMC does not work for a period of time, so that the fan is in a management blank window period. Based on the above problems obtained by analysis, the inventor creatively proposes that programmable logic device editing in single boards is utilized to realize transmission of speed regulation values among the single boards, and management single boards in at least two single boards are used for frame management, so that the increased software development and maintenance cost caused by the frame management by utilizing the modified BMC is reduced. Meanwhile, because simple speed regulation values are transmitted among the single boards, the speed regulation can be realized by using programmable logic devices in the single boards without using GE gigabit Ethernet high-speed lines in the prior art, and hardware cost is reduced. Moreover, the time from power-on starting to normal operation of the programmable logic device is short, and the programmable logic device belongs to millisecond level, so that the fan is prevented from being in a management blank window period for a long time.
A second embodiment of the present invention relates to a frame management apparatus. The second embodiment is a further improvement of the first embodiment, and the main improvement lies in that: in a second embodiment of the present invention, the machine frame management device further includes at least one power module, and the management of the power module in the machine frame is implemented without modifying the BCM.
As shown in fig. 4, the machine frame management device according to the present embodiment specifically includes: the chassis body (not shown in the figure), the management board 101, the managed board 102, the managed board 201, the fan 103, the fan 104, the fan 105, the power module 202, the power module 203, the EPLD1012 are connected to the fan 103, the fan 104, and the fan 105, and the EPLD1012 is further connected to the power module 206 and the power module 207, respectively. That is, in this embodiment, the management board 101 needs to manage 3 boards including itself, and needs to compare the sizes of the field 1, the field 2, and the field 3 in the figure and send the largest one of the two to the fan.
Specifically, the power supply module 202 and the power supply module 203 are provided to avoid that one of the power supply modules fails to work, so that the whole device cannot work. The operation of the power module 202 is described below, and the operation of the power module 203 is similar to that of the power module 202, so the operation of the power module 203 is not further described to avoid redundancy.
The power module 202 may be configured to supply power to each board in the machine frame, and the management board 101 may monitor and manage the power module 202. The monitoring management mode can be as follows: the power module 202 detects whether its own operation information satisfies a preset standard, and the operation information may be, for example: power supply value, power supply power consumption, power supply temperature, etc., the preset standard can be set by those skilled in the art according to actual needs. For example, if it is detected that the power supply temperature is too high and the power consumption is too large, an alarm message may be sent to the management board 101. After receiving the alarm information, the management board 101 may report to the machine room management center to notify the staff to process the alarm information. Meanwhile, due to the failure of the power module 202, the whole device can continue to operate normally through the power module 203.
Further, some pins in the EPLD1012 may be defined by programming as an I2C interface that can be used to transmit the alarm information, and the management board 101 may be connected to the power module 202 through the I2C interface of the EPLD1012. The alarm information received by the management board 101 may be alarm information sent by the power module 202 and received through the I2C interface of the EPLD1012.
Compared with the prior art, the management of the power module in the machine frame is realized on the premise of not modifying the BCM by the embodiment, the alarm information is sent, the abnormity can be processed in time, and the reliability of machine frame management is further enhanced.
A third embodiment of the present invention relates to a frame management apparatus. The third embodiment is a further improvement of the second embodiment, and the main improvements are as follows: in a third embodiment of the present invention, a subrack management apparatus includes: at least three single boards, wherein a management single board in the at least three single boards comprises: the master management single board and the slave management single board adopt a master-slave management working mode to avoid faults and are beneficial to improving the reliability of management.
As shown in fig. 5, a machine frame management device according to a third embodiment of the present invention specifically includes: a machine frame body (not shown), a master management board 301, a slave management board 302, a managed board 303, a managed board 304, a fan 103, a fan 104, a fan 105, a power module 202, and a power module 203, wherein the EPLD3012 of the master management board 301 is connected to the fan 103, the fan 104, and the fan 105, and the EPLD3022 of the slave management board 303 is connected to the fan 103, the fan 104, and the fan 105. EPLD3012 and EPLD3022 are also connected to power module 206 and power module 207, respectively.
Specifically, both master management board 301 and slave management board 302 may receive the throttling value of each board, and in fig. 5, EPLD3012 and EPLD3022 receive the respective throttling values sent from managed board 303 and managed board 304. EPLD3012 of primary management board 301 is configured to send the largest speed-adjusting value of the speed-adjusting values of the boards to the fan; the EPLD3022 of the slave management board 302 is configured to send, to the fan, the maximum speed-adjusting value among the received speed-adjusting values of each board when it is detected that the received speed-adjusting value of each board remains unchanged within a preset time, where the preset time may be set by a person skilled in the art. That is, in this embodiment, when master management board 301 fails, slave management board 302 may manage the entire subrack as a standby device to maintain the normal operation state of the entire subrack.
Furthermore, the managed single board needs to send its own speed-adjusting value to the master management single board and the slave management single board simultaneously, and the point-to-multipoint transmission can be realized because the inter-board communication interface can be a low-speed serial communication interface. For example, in fig. 5, managed board 303 may send a throttling value, which is received by master management board 301 and slave management board 302, respectively.
Compared with the prior art, the method adopts a master-slave management working mode to avoid faults and is beneficial to improving the reliability of management. Furthermore, in the prior art, referring to fig. 2, GE between boards transmits and receives differential signals, and point-to-point connections are performed, that is, 1 line in the figure is actually 4 lines, so 20 lines are actually needed in fig. 2. In the present embodiment, the inter-board communication may use a low-speed serial signal, such as RS232, which is a single-ended signal with 1 wire, and supports point-to-multipoint connection, so that in fig. 5, actually 3 wires are required, and therefore, in comparison, the inter-board connection wires in the present embodiment are greatly reduced.

In addition, in order to highlight the innovative part of the present invention, elements that are not so closely related to solving the technical problems proposed by the present invention are not introduced in the present embodiment, but this does not indicate that other elements are not present in the present embodiment.
