Abstract

Provided is a server device as an information processing device connected to a client device via a communication path. The server device includes: a port; a command processing unit which processes a command; and a preprocessing unit arranged between the port and the command processing unit. The server device can suppress a delay of command processing even when the port is shared by a plurality of client devices. The preprocessing unit checks whether a command received by the port is a single command indicating a single process or a composite command which can contain a plurality of instructions. If the received command is a single command, the preprocessing unit sends it directly to the command processing unit via a first channel. If the received command is a composite command, the preprocessing unit divides it into single commands and sends them to the command processing unit via a second channel.

Description

Information processing apparatus, information processing system, and control method

This case relates to an information processing apparatus, an information processing system, and a control method.

The server device as the information processing device is connected to a client device as a terminal device that causes the server device to perform original business, for example, deposit / withdrawal processing business in a bank. Then, the server device processes the original work such as the updating of the deposit balance of each account based on the deposit and withdrawal information sent from the client device. Such a server device is connected not only to a client device that is originally required for the execution of business, but also to a management device as a terminal device for system control. The server device responds to a command from the management device. The state of the sensor of each part in the server device is acquired and transmitted to the management device, and operations such as power on / off are performed. As an interface for remotely monitoring and operating a server device regardless of the type of OS (Operating System) operating on the server device, for example, an intelligent platform management interface (IPMI: Intelligent Platform Management Interface) is known. In this IPMI, a command conforming to this IPMI is prepared. When a command is sent from the management device to the server device, the server device collects sensor information or performs operations such as power on / off in accordance with the command, and collects sensor information and turns the power on. A response as a response indicating the normal / abnormal end result of the operation such as / off is transmitted to the management apparatus. There are two types of commands. One is a standard command for causing the server apparatus to execute a single detection process, for example, reading the value of a certain sensor in the server apparatus and returning the read result as a response. The other type is a command called OEM (Original Equipment Manufacturing) command. For example, a plurality of sensors in a server device are specified, and the values of the plurality of sensors are read and transmitted to the management device. It is a command that can include execution of a plurality of detection processes.

Here, a case where a plurality of (for example, two) management devices for system control are connected to one server device will be described. For example, when there are a plurality of management rooms where management devices are placed, or when there are a plurality of management personnel even in one management room and one management device is assigned to each management personnel, a plurality of management devices are provided. Necessary.

The server device has a first input / output port and a second input / output port, the first management device is connected to the first input / output port, and the second management device is connected to the second input / output port. In some cases, if the server device has a plurality of input / output ports, it is necessary to increase the number of circuit boards for the input / output ports. On the other hand, if one input / output port of a server device is shared by connecting a plurality of management devices to the server device via a hub, an increase in cost is avoided. However, in this case, when a command is transmitted to the server device from a plurality of management devices sharing the input / output port, the processing of the command received later is awaited. Become. In particular, when an OEM command instructing the execution of a plurality of processes is received first, the process waits for a long time until the processing of the OEM command is completed. It is a big problem because it affects.

Here, the device configuration information is acquired by the IPMI OEM command, the macro command for performing a plurality of processes corresponding to the OEM command is decomposed into a plurality of single commands, and the macro command and the single command are mixed. Is input.

The problem of the information processing apparatus, the information processing system, and the control method disclosed herein is to suppress a delay in command processing even when a plurality of terminal apparatuses share one port of the information processing apparatus.

The information processing apparatus of the present disclosure is connected to a terminal device via a communication path, performs processing according to a command received from the terminal device, and transmits a command processing result to the terminal device Device. Here, the information processing apparatus disclosed herein includes a port, a command processing unit, and a pre-processing unit. The port plays a role of performing communication with the terminal device.

It is a figure which shows an example of the data structure of an OEM command. It is a figure which shows an example of the data structure of the response with respect to an OEM command. FIG. 9 is a sequence diagram of command processing in the embodiment shown in FIGS.

Hereinafter, the embodiment of this case will be described.

FIG. 1 is a block configuration unit of a server apparatus as an information processing apparatus according to an embodiment of the present case.

The server device 10 is a server device equipped with an intelligent platform management interface (IPMI: Intelligent Platform Management Interface). The server device 10 is connected to two management devices A and B as terminal devices for system control via a LAN (Local Area Network).

The server device 10 includes a system control unit (MMB: Management Board) as a service processor (Service Processor), two system boards 12, two IO (Input Output) devices 13, two power supplies 14, and 2 A fan 14 (herein referred to as “component” as a generic term) is provided. These are merely examples, and other types of parts may be included, and the number is not limited to two. Each of the components 12 to 14 has

sensors

121, 131, 141, and 151, respectively, and is connected to the system control unit 11 through an I2C (Inter-Integrated Circuit) interface. Here, one sensor is representatively shown for each component, but a number of sensors may be provided.

The management device can send a command to the system control unit via the LAN to acquire the sensor state and change the sensor setting value. A plurality of management devices (in this case, typically two management devices A and B) can be connected by interposing a LAN hub, and commands and IPMI-compliant commands can be exchanged with the system control unit 11. Responses are sent and received.

Hereinafter, the system control unit of the server device 10 will be mainly described.

In the following, the description of the present embodiment will be given once and the configuration of the system control unit as a comparative example will be described.

FIG. 2 is a block diagram showing a configuration of a system control unit as a comparative example.

In the case of the comparative example shown in FIG. 2, the overall configuration shown in FIG. 1 is the same as that of the embodiment, and FIG. 1 is adopted as it is. However, here, the system control unit is denoted by reference numeral “11A” to indicate that it is a comparative example.

The system control unit 11A as a comparative example shown in FIG. 2 includes a port 111, an IPMI control unit 112, and a driver 113. The IPMI control unit 112 includes a logical channel unit 1121, a command processing unit 1122, and a device unit 1123. Here, the port 111 includes a circuit board as hardware, and is connected to the management apparatuses A and B via a LAN hub via a LAN. The management apparatuses A and B and the server apparatus 10 are connected to each other. (See FIG. 1).

In addition, the IPMI control unit 112 includes hardware such as a CPU (Central Processing Unit) that executes a program and software that is executed on the hardware to realize IPMI.

Here, the storage unit 115 stores a program that is executed by the CPU and builds the IPMI control unit 112 on the CPU. This program includes program parts for constructing a logical channel unit 1121, a command processing unit 1122, and a device unit 1123 constituting the IPMI control unit 112 on the CPU. Each of these program parts is executed by the CPU, so that a logical channel unit 1121, a command processing unit 1122, and a device unit 1123 are constructed. The logical channel unit 1121 plays a role of logically associating the port 111 and the command processing unit 1122. Further, the command processing unit 1122 acquires a sensor state, changes a sensor setting, and the like through the device unit 1123 and the drive unit 113, and generates a response representing the acquired sensor state. Further, the device unit 1123 logically associates the command processing unit 1122 with the drive unit 113.

Here, the storage unit 115 also stores a program called a driver. The drive unit 113 is constructed by executing this driver by the CPU. The drive unit 113 is connected to the components 12 to 15 via the I2C interface, and acquires the state of each sensor 121 to 151 that is a physical layer, changes the settings, and the like.

FIG. 3 is an explanatory diagram of the logical channel section in the comparative example shown in FIG. The logical channel section itself has the same configuration in the embodiments described later.

The logical channel unit 1121 has software executed on the CPU as described above. In the logical channel unit 1121, a plurality of logical channels (CH # 4 and CH # B) are formed in the CPU into which the software has been read in order to have versatility. On the other hand, if the management apparatus A and the management apparatus B try to divide the ports 111, it is necessary to physically add circuit boards, which increases costs. Further, the management apparatus A and the management apparatus B need to set different IP addresses as the IP (Internet Protocol) address of the server apparatus 10. Furthermore, there are cases where expansion itself is physically impossible, for example, when there is no empty slot in an IO (Input Output) slot such as PCI (Peripheral Component Interconnect). Therefore, here, the management apparatus A and the management apparatus B share one port 111 by interposing a LAN hub between the management apparatus A and the management apparatus B. In this case, an IPMI command issued by either management device A or management device B is received by one shared port 111 and one logical channel assigned to this port 111 ( In FIG. 3, the command processing is performed on the logical channel CH # 4). Therefore, when a command is received from a plurality of clients at almost the same timing, the command processing unit 1122 performs processing sequentially from the command received first, as described with reference to FIG.

FIG. 4 is a sequence diagram of command processing in the comparative example shown in FIGS.

Here, first, there is a request as a request by the OEM command from the management apparatus A, and the OEM command is input to the command processing unit via the logical channel CH # 4 and executed (S2). Here, the OEM command can include a large number of processes such as requesting acquisition of the states of a large number of sensors. Here, it is assumed that an OEM command requesting acquisition of the status of 32 sensors consisting of Sensor # 0 to Sensor # 31 is received and the OEM command is executed. In this case, the command processing unit sequentially acquires the states of Sensor # 0 to Sensor # 31. Here, since a large number of sensor states are acquired, a considerably long time is required. When the acquisition of the status of all the sensors (Sensor # 0 to Sensor # 31) is completed, a response reporting the status of these sensors is returned to the management apparatus A via the logical channel CH # 4 (S4) ( S5).

Here, it is assumed that another request from the management apparatus B is received immediately after receiving the OEM command issued by the management apparatus A (S3). This request is waited until the execution of the OEM command received from the management apparatus A is completed and a response corresponding to the OEM command is returned, that is, until step S5. The request from the management apparatus B is subsequently executed (S6), and the response is returned to the management apparatus B via the logical channel CH # 4 (S7) (S8).

In this case, even if the request issued by the management apparatus B is an urgent request, it will wait for a long time until the execution of the OEM command received from the management apparatus A, resulting in a performance problem.

Based on the above comparative examples, the description returns to the embodiment of the present case.

FIG. 5 is a block diagram showing the configuration of the system control unit in the present embodiment.

In the system control unit 11 shown in FIG. 5, a pre-processing unit 114 is added between the port 111 and the IPMI control unit 112, as compared with the system control unit 11A of the comparative example shown in FIG. Similarly to the IPMI control unit 112, the pre-processing unit 114 also has a program for the pre-processing unit stored in the storage unit 115, and is constructed on the CPU by the CPU executing the program. . The other points are the same as those of the system control unit 11A of the comparative example described with reference to FIG.

FIG. 6 is a block diagram showing the configuration of the pre-processing unit and the connection relationship with the logical channel unit in the embodiment shown in FIG.

The pre-processing unit 114 decodes the command whether the command received at the port 111 is a standard command or an OEM command, and changes the processing according to the decoding result. That is, for the standard command, the pre-processing unit 114 transmits the standard command to the command processing unit 1122 via the logical channel CH # 4. As for the OEM command, the OEM command is divided into standard commands in the pre-processing unit 114, and the divided single command is transmitted to the command processing unit via another logical channel CH # B. Further, the pre-processing unit 114 transmits the response received from the logical channel CH # 4 to the port 111. Further, in the pre-processing unit 114, for the response received from the other logical channel CH # B, the response corresponding to each standard command obtained by dividing the OEM command is combined with the response corresponding to the OEM command to the port 111. Send it.

The pre-stage processing unit 114 includes a selector 1141 and a division / combination unit 1142. The selector 1141 is connected to the port 111, one logical channel CH # 4, and the dividing / combining unit 1142. Divider / combiner 1142 is connected to selector 1141 and the other logical channel CH # B. The selector 1141 receives a command from the port 111, and when the command is a standard command, sends the standard command to the command processing unit 1122 via the logical channel CH # 4. Further, when the command received from the port 111 is an OEM command, the selector 1141 sends the OEM command to the dividing / combining unit 1142. Further, the selector 1141 sends the response received via the logical channel CH # 4 and the response received from the dividing / combining unit 1142 to the port 111 for transmission.

Further, the dividing / combining unit 1142 divides the OEM command received from the selector 1141 into standard commands, and sends the divided standard commands to the command processing unit 1121 via the logical channel CH # B. The division / combination unit 1142 combines a response corresponding to each of the divided standard commands received from the command processing unit 1122 via the logical channel CH # B with the response of the OEM command before division. 1141 is sent.

FIG. 7 is a diagram showing an example of the data structure of the OEM command.

Here, the OEM command has a 2-byte structure, a command code indicating the type of the command is described in the 0th byte, and a part number for identifying the part is described in the 1st byte. As described above, each of the system board 12, the IO device 13, the power supply 14, and the fan 15 shown in FIG. 1 is referred to as a “component”. In the first byte of the OEM command shown in FIG. 7, a part number specifying each “part” is described. That is, the OEM command shown in FIG. 7 is a command that specifies that processing corresponding to the command code specified by the 0th byte is to be collectively executed for the “component” specified by the 1st byte.

FIG. 1 shows, as an example, a case where one sensor 121 to 151 exists for each of parts 12 to 15. However, there may be a large number of sensors in one “component”.

Here, it is assumed that the command code of the OEM command representing the command called “GetSensorState request” instructing to acquire the sensor state is described as the command code of the OEM command shown in FIG. In this case, the states of all the sensors mounted on the “component” designated by the first byte are acquired. Here, it is assumed that a total of 32 sensors, Sensor # 0 to Sensor # 31, are mounted on the “component” designated by the first byte.

When the selector 1141 constituting the pre-stage processing unit 114 shown in FIG. 6 receives an OEM command as exemplified in FIG. 7, the received OEM command is sent to the dividing / combining unit 1142. The dividing / combining unit 1142 divides the OEM command received from the selector 1141 into standard commands. Specifically, in the example described here, 1 of all the sensors (here, 32 sensors including Sensor # 0 to Sensor # 31) mounted on the “component” designated by the first byte. It is divided into 32 standard commands corresponding to each. These 32 standard commands are commands for instructing acquisition of the state of each one sensor. These 32 standard commands are sequentially sent from the logical channel CH # B to the command processing unit 1122.

FIG. 8 is a diagram illustrating an example of a data structure of a response to the OEM command. The response shown in FIG. 8 is an example of a response to an OEM command called “GetSensorState request” instructing acquisition of the state of a sensor mounted on a certain “component”. Here, a response corresponding to the command “GetSensorState request” is referred to as a “GetSensorReading response”.

As shown in FIG. 8, a command code is recorded in the 0th byte of the response, and a completion code indicating that the processing for the command code is completed in the 1st byte. Further, information indicating the state of each sensor of Sensor # 0 to Sensor # 31 is recorded in each of the third to 33rd bytes.

6 is input to the dividing / combining unit 1142 shown in FIG. 6 through the logical channel CH # B from the command processing unit 1122 for each of the standard commands divided into a large number as described above. The division / combination unit 1142 combines the responses to the standard commands with the responses corresponding to the OEM command before the division as shown in FIG. The combined response as shown in FIG. 8 is sent to the port 111 via the selector 1141, and is sent from the port 111 to the client that issued the OEM command.

FIG. 9 is a sequence diagram of command processing in the embodiment shown in FIGS.

Here, first, the management apparatus A issues a “GetSensorState request” as an OEM command instructing acquisition of the states of all the sensors mounted on the designated “component” (S1). Then, the “GetSensorState request” is divided into a plurality of standard commands instructing acquisition of the state of each sensor in the pre-processing unit (S2). Of the plurality of standard commands obtained by this division, a “GetSensorReading request (Sensor # 0)” instructing acquisition of the sensor state of Sensor # 0 is sent to the command processing unit via the logical channel CH # B. (S3). The command processing unit acquires the state of the designated Sensor # 0, and returns a “GetSensorReading response” indicating the state of Sensor # 0 to the preceding processing unit via the logical channel CH # B. Next, similarly, a “GetSensorReading request (Sensor # 1)” instructing acquisition of the state of Sensor # 1 is sent from the preceding processing unit to the command processing unit via the logical channel CH # B (S4). The command processing unit acquires the state of the designated Sensor # 1, and returns a “GetSensorReading response” indicating the state of Sensor # 1 to the upstream processing unit via the logical channel CH # B. While this is being repeated for each sensor (Sensor # 0 to Sensor # 31), one of the standard commands (here, this standard command is referred to as "other request") is issued from the management apparatus B (S5). This “other request” is input to the command processing unit via the pre-processing unit and the logical channel CH # 4. The command processing unit executes the processing of the “other request”, and the “other response” corresponding to the “other command” is returned to the management apparatus B via the logical channel CH # 4 and the previous processing unit.

Thereafter, the processing of each “GetSensorState request”, which is a standard command obtained by dividing the OEM command issued by the management apparatus A, is further continued.

This process is continued until the pre-processing unit receives a “GetSensorReading response (Sensor # 31)” for Sensor # 31 (S6).

Thereafter, in the pre-processing unit, sensor information # 0 to # 31 for all sensors (Sensor # 0 to Sensor # 31) are combined into one response (see FIG. 8). This combined response, that is, “GetSensorReading” corresponding to the “GetSensorState request” as the OEM command issued by the management apparatus A in step S1 is returned to the management apparatus A (S8).

As shown in FIG. 9, in this embodiment, when another standard command is received during execution of the OEM command, the standard command can be processed without waiting for the OEM command to end.

Furthermore, according to the present embodiment, as will be described below, it is possible to make a common component compatible with the program that implements the IPMI control unit. The OEM command is a command that can be added / changed according to a user request. For example, when a new OEM command is to be added, in the case of the comparative example shown in FIG. 2, it is necessary to modify the command processing unit 1122 in the IPMI control unit 112 so that the new OEM command can be interpreted. If this is done, the IPMI control unit 112 itself is customized, and the compatibility of the IPMI control unit cannot be achieved. On the other hand, in the case of the present embodiment, the pre-processing unit 114 shown in FIG. 5 may be modified, and the IPMI control unit 112 itself may remain the standard, and the IPMI control unit can be made a common part.
