The present invention relates to a method and apparatus for providing status information of a board using an IPMI message in an ATCA system. In the current AdvancedTCA system, a board such as board seal, hernia information, or whether a board is powered on without additional hardware modification or modification ATCA system configuration that provides status information to the main processor using IPMI messages.

AdvancedTCA, which is gradually becoming a standard in the hardware aspect of the system, is now developed by PICMG in cooperation with more than 100 major telecommunication system companies in foreign countries, and many equipment manufacturers and service providers have developed PICMG 3.x and AdvancedTCA specifications. The trend is to apply this gradually. The ultimate goal of the AdvancedTCA specification is to provide a highly available hardware platform for carrier-class communications applications. In line with these objectives, in the future, even domestic and overseas telecommunications operators will tend to use the communication system that complies with the AdvancedTCA standard. Also, the newly developed communication system will take the system structure that complies with the Advanced-TCA standard.

In an AdvancedTCA system, however, all boards mounted in the system must have extra pins to provide this information to the connectors connected to the backplane in order to provide board status information to the main processor.

However, in order to provide this information in an AdvancedTCA system, you must have extra pins to provide this information in the connector connected to the backplane. According to the AdvancedTCA specification, the connectors connected to the backplane are divided into Zone 1, Zone 2, and Zone 3, and the Zone 1 and Zone 2 areas are predefined pins and cannot be used as other pins. Since it is allocated to pins connected to the rear transfer module, it is not suitable as an area for providing board status information as described above. In addition, the current AdvancedTCA specification has its limitations in providing seamless interoperability between different system manufacturers or different functional modules without adding or changing hardware.

The present invention provides a method for providing status information of the board for the purpose of providing a smooth interoperability between different system manufacturers or different functional modules in the current AdvancedTCA standard that defines an open standard hardware platform to solve the above technical problem. The purpose of this paper is to propose a configuration method of AdvancedTCA system that can provide interoperability by using IPMI message without adding or modifying hardware of system while complying with the standard of system defined in AdvancedTCA.

According to a preferred embodiment of the present invention for achieving the above technical problem, a method of providing status information of a board using an IPMI message in an ATCA system may include a first board equipped with a main processor of an ATCA system (Advanced Telecom Computing Architecture). Requesting hardware status information of the second board from another board, the second board; an intelligent protocol management controller (IPMC) mounted on the first board and an IPMB (Intelligent) between the IPMC in the second board; Receiving an Intelligent Platform Management Interface (IPMI) message including hardware status information of the second board by communication using a Platform Management Bus (PMI) and transmitting the received IPMI message by the IPMC in the first board. And forwarding to the main processor.

In accordance with another aspect of the present invention, an apparatus for providing status information of a board using an IPMI message in an ATCA system requires hardware status information of each board in an Advanced Telecom Computing Architecture (ATCA) system or the board. Receiving the hardware status information request from the main processor and converting the received hardware status information request into an IPMI (Intelligent Platform Management Interface) message form each board in the system. And an intelligent protocol management controller (IPMC) that receives hardware state information of each of the boards and provides them to the main processor, and is located between the main processor and the IPMC to receive the hardware state information request of the main processor. Deliver to IPMC It is configured to include the IPMC is received by the hardware state of each board (Complex Programmable Logic Device) CPLD to pass information to the main processor or FPGA (Field Programmable Gate Array) chip.

According to another preferred embodiment of the present invention for achieving the above technical problem, the apparatus for providing status information of a board using an IPMI message in an ATCA system may request hardware status information for each board in an ATCA system (Advanced Telecom Computing Architecture). Each board in the system by generating an IPMI message or receiving the generated IPMI message through a communication bus directly from the main processor and a main processor for processing hardware state information collected from each board. Or an IPMC (Intelligent Protocol Management Controller) for performing a bridge function and transmitting the received data, or receiving hardware state information of each board from each of the boards in the form of an IPMI message to the main processor.

Hereinafter, with reference to the accompanying drawings, it will be described with respect to a preferred embodiment of the present invention.

1 is a diagram illustrating a management structure of a general AdvancedTCA system.

Referring to FIG. 1, in general, all boards 102 except a shelf manager 101 are intelligent protocol management controllers (IPMCs) that control functions such as power of the board itself, sensors, and ports connected to the backplane. The self manager 101 manages and controls all the boards 102 through the IPMC 103 connected to the IPMB bus 104.

AdvancedTCA system must support hardware management function conforming to Intelligent Platform Management Interface (IPMI) standard. Shelf-external system management function (105) of AdvancedTCA system supports SNMP, IPMI over RMCP, CLI, Web By properly utilizing the interface, it is possible to provide the hardware management function of the system to the administrator connected to the external network.

The present invention is an embodiment of the AdvancedTCA system for providing a board equipped with the main processor with the hardware state information of the board provided in the existing system without additional hardware modification or modification to the AdvancedTCA system, while complying with the specifications defined in the AdvancedTCA as an embodiment thereof It can suggest how to configure.

Currently, existing systems have various structures, such as different racks and backplanes, but the main processor maintains the same status information for each board mounted in the system. Among them, board seal, hermetic and power are mainly made at the hardware level, and at least two pins are connected to each other through the backplane to provide board status information. Therefore, in order to provide the above information, a separate path except for a data path must be added to the backplane installed in the rack.

For example, in the case of a system with 14 slots, in order to provide information on board seal, hermetic power, and power supply, two kinds of information are provided to the main processor in 13 slots except for a board equipped with a main processor. 26 routings are made through the backplane. This will be described in detail in the following drawings.

FIG. 2 is a diagram illustrating a configuration of a backplane for providing board real and hernia information to the RP in a redundant RP system of 14 slots in a typical AdvancedTCA system.

This shows an example of the configuration of a backplane for providing board real and hernia information 202 to the routing processor 201 in a 14-slot redundant routing processor (RP) system.

For redundant RPs, the backplane must provide the same information to two RPs simultaneously, requiring twice as much routing as the backplane (13 routings) in a single system, requiring a total of 26 routings. In the example of FIG. 2, it is shown that separate routing is performed for each RP (202, 203). In order to provide information on whether board power is applied in addition to board seal and hermetic information, one additional routing is required for each board, and the backplane requires twice as much routing as in FIG. This is necessary.

3 is a view showing the internal configuration of the RP board in the AdvancedTCA system according to the present invention.

This is an example of the internal configuration of the RP board 301 in a typical system shows an internal block diagram of the board that processes the information on the seal, hernia information, and whether the board power is applied to the board input from the backplane. Information input from the backplane connector 302 is connected to the CPLD or FPGA chip 303 and the main processor 304 connects to the CPLD or FPGA chip 303 to a communication bus 305 such as a local bus or a PCI bus. The main processor may manage the state information of each board by connecting the CPLD or FPGA chip 303 through the communication bus to read information provided through the backplane.

The status information provided by each board is composed of hardware. As an example, the board's seal and stripping information can be handled by pull-down resistors, and the information on whether the board power is applied can be handled by pull-up resistors. .

4 is a shape diagram of a data backplane when the fabric interface defined in the AdvancedTCA system according to the present invention is in the form of a full mesh.

The current AdvancedTCA specification focuses on the functionality of the hardware and self-manager, and defines various data backplane structures (full mesh, dual star, etc.) depending on the structure of the hub slot.

Referring to FIG. 4, the fabric interface 402 of the backplane 401 shape defined in the AdvancedTCA specification shows the data backplane 401 shape of a full mesh. In this case, the pins assigned to the Zone 1 area are used to connect the IPMB bus and power, and have the same pin map structure in all slots. Zone 2 zones are allocated to the base interface 403, the fabric interface 402, the update port 404, and the like, and have the same pin map structure in all slots except the hub slot 405.

The hub slot 405 occupies two middle slots and performs a central function of connecting to each node slot 406 through the base interface 403 and the fabric interface 402. The base interface 403 structure has the same shape as the fabric interface 402 structure.

In addition, the first base interface Shmc of the redundant hub switch 405 is defined to be connected to the Ethernet port of the self manager in all data backplane structures. In addition to the data backplanes defined in the AdvancedTCA specification, another backplane that makes up the self is called the control backplane, which provides slots for mounting the self manager, alarm boards, and fans. The control backplane can take a variety of forms depending on the self-configuration and is primarily used to interconnect the IPMB bus and the Ethernet port of the self-manager with the data backplane.

As described above, the AdvancedTCA specification describes the pin maps defined in the Zone 1 and Zone 2 areas, respectively, so that pin maps cannot be allocated to the Zone 1 and Zone 2 areas to provide status information used in the existing system. In the AdvancedTCA system, a zone 3 zone is defined separately above the zone 2 zone so that the board maker can define and use it only when connecting using a rear transfer module (RTM) board.

 Therefore, in the area of the connector of the backplane provided by the AdvancedTCA system, not only is it difficult to assign a pin map for providing the state information of the existing system, but even if a new pin map is defined, creating a new backplane is a difference between different functional modules. It is contrary to the basic intent of the AdvancedTCA system to provide seamless interoperability.

Older system builders can tailor the racks and backplanes to the needs of those using them, making backplanes and racks easy to modify to provide board status information, while current AdvancedTCA systems provide racks and backplanes. Since the company produces the system in compliance with the AdvancedTCA standard, it is not possible to use the existing state information providing method of the board as it is, and the present invention defines an open standard hardware platform so that different system manufacturers or different functional modules can be used. It is possible to provide a smooth interoperability between the two.

As a system manufacturer, it is not necessary to develop all the functional modules of the system independently, thereby reducing the development time of the system and concentrating the development capability on specific functional modules, thereby securing the stability and reliability of the system and reducing the development cost. You will be able to enter the market in a timely manner. In addition, telecom operators can build systems with different manufacturers for each function module, eliminating the irrationality of relying on a specific manufacturer for the whole system, and using a single standardized platform, which enables continuous system upgrade and operation efficiency. Will be.

5 is a flowchart illustrating a method of providing board state information using an IPMI message in an ATCA system according to an embodiment of the present invention.

Referring to FIG. 5, when a first board equipped with a main processor of an ATCA system requests hardware state information of the second board as a second board in the system (501), the first board is connected to the first board. Receiving an IPMI message including the hardware status information of the second board by the communication using the IPMB between the mounted IPMC and the IPMC in the second board (502), the IPMI message in the first board to the received IPMI message Transfer to the main processor in the first board (503). Here, the hardware state information of the second board is information on whether the second board is seal, hernia or whether power is applied.

The request to the second board 501 or the reception of an IPMI message from the second board 502 is performed using IPMB but independent of the shelf manager on the system, in particular the request to the second board ( 501 is transferred to the second board using an IPMI message. In addition, the request to the second board 501 is performed when the actual main processor requests hardware state information of the second board from a complex programmable logic device (CPLD) or field programmable gate array (FPGA) chip in the first board. The CPLD or the FPGA chip receiving the request requests the hardware state information to the IPMC in the first board, and the IPMC transmits the hardware state information request to the second board in the form of an IPMI message. Here, the main processor periodically requests such information, and the IPMC in the first board can save time by transmitting the request to the second board in advance of the request of the main processor.

Thereafter, the IPMI message received by the IPMC (502) is transmitted to the main processor via a CPLD or FPGA chip in the first board, or stored in an internal register of the CPLD or FPGA chip so that the main processor reads it.

This IPMI message can be standardized with the message defined in the IPMI specification. In this case, the request for hardware status information from the first board to the second board is a Get Sensor Reading message from the IPMI specification. The IPMI message is a reply message of the Get Sensor Reading message. In particular, the Get Sensor Reading message includes a sensor number of the second board, and the reply message includes state information of a Hot-Swap sensor in the second board.

6 is a configuration diagram of an ATCA system including an apparatus for providing board state information using an IPMI message according to an embodiment of the present invention.

This is an example of an AdvancedTCA system consisting of 5 slots and shows a system configuration for providing hardware status information using an IPMI message. Of course, even in the 14-slot AdvancedTCA system, all configurations are identical except for the difference in the number of slots.

Referring to FIG. 6, a switch board equipped with a main processor (in this example, a main processor is mounted on a switch, 601) is duplicated, and the IPMB bus 602 includes the IPMC 603 and the Shelf Manager of each board as in the AdvancedTCA standard. 605 is connected to each other and has a redundant structure to transmit a stable IPMI message. The IPMB bus 602 is mainly for transmitting IPMI messages between the IPMCs 603 and 604 and the shelf manager 605 of each board. The Shelf Manager 605 sends an IPMI message requesting status information to the IPMCs 603 and 604 of each board, and the IPMC 603 and 604 of each board sends an IPMI reply message corresponding to the Shelf Manager 605. do.

As described above, the present invention provides a method of providing hardware state information to the main processor using the IPMI message. When the IPMC 604 of the switch board (board with the main processor, 601) sequentially requests the board's hardware status information from the IPMC 603 of the other board, the IPMC 603 of each board switches the status information of the board. It is configured to report to the IPMC 604 of the board (board equipped with the main processor, 601).

At this time, the IPMI message for which the IPMC 604 of the switch board (the board equipped with the main processor, 601) requests the board status information from the IPMC 603 of the other board is an example of Get Sensor among the IPMI messages defined in the IPMI specification. It is possible to apply the reading message 606 as it is. It is also possible to send and receive IPMI messages between IPMCs using new customized IPMI messages for hardware status information. The IPMC 603 of each board receiving this message transmits a reply message 607 of Get Sensor Reading defined in the IPMI specification to the IPMC 604 of the switch board. This allows an AdvancedTCA system that defines a standard hardware platform so that IPMCs mounted on each board can use each other's IPMI messages to collect hardware status information from other boards mounted on the platform and provide it to the main processor without the involvement of the self-manager. will be.

The method of transmitting and receiving the IPMI message may be applied to any other slot position in which the main processor is mounted in a manner suitable for the IPMI specification. Using this IPMB bus eliminates the need for routing complex backplanes previously used, which eliminates the need to modify the backplane and add new backplanes.

7 is a diagram illustrating a Get Sensor Reading message defined in the IPMI specification according to an embodiment of the present invention.

This is a message format defined in the IPMI specification of Get Sensor Reading. The format of the request message 701 needs to additionally record one byte of the sensor number in the IPMI message, which can be transmitted to the receiving IPMC. The reply message format 702 has a length of 4 bytes, although the message length varies depending on the content of the message. According to an embodiment of the present invention, the board state information may be defined as follows according to the board information (FRU Hot-Swap State, 703) located in the fourth byte in the reply message 702 of Get Sensor Reading.

This definition can be defined differently depending on the system. The IPMC 603, which sends a reply message of Get Sensor Reading, carries the status information of the hot-swap sensor of the board in this byte and sends the hardware status information to the IPMC 604 that has requested the hardware status information.

As an example, board mounting can be represented by M1 through M6, power supply by M3, M4, and M5, power off by M1, M2, and M6, and board hernia by M0, M7, and No ACK. This approach eliminates the need to modify the backplane and existing boards, only the board with the main processor that wants to manage the state information of the existing boards.

8 is a diagram illustrating a board configuration on an AdvancedTCA equipped with an IPMC, CPLD / FPGA and a main processor using an IPMI message according to an embodiment of the present invention.

This is an example of an AdvancedTCA board with a main processor. Depending on the internal configuration, the main function may be replaced by another chip. The switch (board with main processor, 801) configuration for managing status information is similar to the configuration of the Routing Processor (RP) of the existing system, so that only the IPMC 804 in addition to the main processor 802 and the CPLD or FPGA chip 803 Only has more added forms. The information provided from the IPMC 804 connected to the Zone 1 connector 805 by the IPMB bus is connected to the CPLD or the FPGA chip 803 by the GPIO pin of the IPMC 804 or the like (806), and the main processor 802 is connected to the CPLD or A communication bus 807, such as a local bus or a PCI bus, is connected to the FPGA chip 803.

The main configuration is the main processor 802 for requesting hardware status information of each board in the ATCA system or processing hardware status information collected from the respective boards, and receiving the hardware status information request from the main processor. An IPMC 804 which transmits a hardware status information request to each board in the system in the form of an IPMI message, receives hardware status information of each board, and provides the hardware status information to the main processor. It includes a CPLD or FPGA chip (803) for delivering to the IPMC and the hardware status information of each of the boards received by the IPMC to the main processor.

There are various methods of providing status information of a board mounted in the system under the above configuration, but the first method is CPLD when the main processor 802 requests status information of other boards from the CPLD or the FPGA chip 803 at regular intervals. Alternatively, the FPGA chip 803 may configure the IPMC 804 to request the status information of another board through the GPIO pin, which is required after the main processor accesses the CPLD or the FPGA chip 803 after a certain period of time. It's a way to get information back.

In the second method, the IPMC 804 obtains the state information of another board in advance and stores it in the internal register of the CPLD or the FPGA chip 803 through the GPIO pins at regular intervals. Alternatively, the method obtains the required state information by reading an internal register of the FPGA chip 803. The number of GPIO pins connected between the CPLD or FPGA chip 803 and the IPMC 804 consists of 26 pins to handle the status information required by the existing system, or transmits the status information of other boards by setting a certain protocol between the two chips. It is possible.

If there is another board including the main processor, the IPMC transmits the IPMI message only when the IPMC is in the board connected to the activated main processor.

9 is a view showing a board configuration on the AdvancedTCA consisting of only the main processor and IPMC according to an embodiment of the present invention.

Referring to FIG. 9, the system generates a hardware state information request for each board in the form of an IPMI message or a communication bus directly from the main processor 901 and the main processor that processes hardware state information collected from each board. IPMC 902 which receives the generated IPMI message and performs a bridge function to each board in the system and transmits it, or receives hardware state information of each board from each board in the form of an IPMI message to provide to the main processor. It consists of.

This is because the main processor 901 and the IPMC 902 connect directly to the communication bus (the serial bus is defined as an example of the bus defined in the IPMI specification), without a CPLD or FPGA chip. When the IPMI message is generated and transmitted to the IPMC 902, the IPMC 902 performs a bridge function to transmit the IPMI message to the IPMC of the corresponding destination, thereby obtaining status information of another board. do.

However, if the switch board is redundant, the main processor of the newly activated board obtains information from the previous main processor or even if the switch board is switched due to the necessity of the switch board or inevitably. It is also possible to request other board status information via IPMC and notify the main processor of new status information based on the received information.

At this time, the IPMC of the deactivated board can never transmit an IPMI message requesting status information. This method is compliant with the AdvancedTCA specification and does not require any changes or replacements to the rack or backplane of the AdvancedTCA system, making it easy to apply the current AdvancedTCA system. The advantage is that it does not use an Ethernet channel and can always update board status information without initializing the base interface.

In addition, when another board including the main processor 901 exists, the IPMC 902 transmits the IPMI message only when the IPMC is in the board connected to the activated main processor. In addition, the main processor 901 may be connected to the IPMC 902 via a communication bus defined in the IPMI specification.

The invention can also be embodied as computer readable code on a computer readable recording medium. Computer-readable recording media include all kinds of recording devices that store data that can be read by a computer system. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disks, optical data storage devices, and the like, which are also implemented in the form of carrier waves (for example, transmission over the Internet). Include. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. In addition, functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers in the art to which the present invention belongs.

Such a method and apparatus of the present invention have been described with reference to the embodiments shown in the drawings for clarity, but these are merely exemplary, and various modifications and equivalent other embodiments are possible to those skilled in the art. Will understand. Therefore, the true technical protection scope of the present invention will be defined by the appended claims.

The present invention provides a communication method between the main processor and the IPMC in the board equipped with the main processor in compliance with the AdvancedTCA standard under the above configuration, and provides hardware status information on whether the board is used in the system, whether the board is used for sealing, dismounting information and power. By providing messages to the main processor, they can provide seamless interoperability between different system manufacturers or between different functional modules under the AdvancedTCA specification, which defines an open standard hardware platform. In addition, the ATCA system can be applied as it is, reducing the additional cost or burden of the system such as modification and replacement of the backplane, and providing the advantage of providing stable status information even when the system is redundant.
