Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hardware development, and particularly relates to a service processing method and related equipment. BACKGROUND

[0002] With the rapid development and update of hard disk technology, the performance of a single hard disk is continuously improved, and the demand of customers for high-performance disks is also continuously increasing. However, with the improvement of the performance of a single hard disk, how to exert the maximum performance of each hard disk under the premise of considering data security becomes a new difficulty.

[0003] For example, an NVMe (Non-Volatile Memory express) SSD (Solid State Disk, Solid State Drive) can be directly used with a CPU (central processing unit) through a PCIe (Peripheral Component Interconnect express) adapter card; a SATA (Serial Advanced Technology Attachment) SSD can be used with the CPU through a built-in SATA and sSATA interface on a motherboard, and can form a soft RAID (Redundant Arrays of Independent Disks) array. NVMe, SAS (Serial Attached SCSI), SATA and the like can be used through a RAID card / SAS card supporting a Tri-mode function, and can form a hard RAID to realize a redundant data protection function. However, the NVMe SSD is used through the PCIe adapter card, and can exert the maximum performance of a single disk when the number of disks is small, but with the increase of the number of disks, the performance will decrease and fluctuate greatly, in addition, the built-in NVMe has no data protection function; the SATA SSD is used in a built-in manner, and its performance has a low bottleneck (2G), which does not meet the current mainstream demand, in addition, the soft RAID will occupy a large amount of CPU resources, and in the case that the CPU usage rate is high, the performance will decrease seriously; the RAID card / SAS card using the Tri-mode function will have reduced performance and great fluctuation when supporting multiple high-performance NVMe SSDs or SAS SSDs, and the performance of each disk is not evenly distributed.

[0004] Therefore, how to exert the maximum performance of the hard disk in different application scenarios and improve the ease of use of the array card where the hard disk is located is a problem to be solved by those skilled in the art. SUMMARY

[0050] The core of the present application is to provide a service processing method, which can exert the maximum performance of a hard disk in different application scenarios and improve the ease of use of an array card where the hard disk is located. Another core of the present application is to provide another service processing method, a service processing device, an electronic device and a computer readable storage medium, all of which have the above beneficial effects.

[0051] In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be introduced below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0052] The embodiments of the present application provide a service processing method.

[0053] Please refer to Figure 1 , Figure 1 A flowchart of a service processing method provided by the present application is shown in FIG. 1. The service processing method can include the following S101 to S103.

[0054] First of all, it needs to be pointed out that the service processing method provided by the embodiments of the present application is applied to an array card firmware, that is, the implementation process of S101 and S103 is executed by the array card firmware.

[0055] S101: When a service command is obtained, the service command is parsed to obtain header information.

[0056] The step is designed to achieve acquisition and analysis of the business command, wherein the business command is a received business command that needs to be executed, so as to achieve corresponding business processing. When the business command is acquired, the command can be parsed to obtain the header information, i.e., Header information, in the business command, wherein the header information contains the hard disk information of the hard disk corresponding to the business command, for realizing hard disk identification, i.e., identifying the hard disk device corresponding to the business command. The acquisition method of the business command is not unique, which can be directly input by the user or automatically triggered in response to a preset condition, and the present application does not repeat the description.

[0057] S102: determining the hard disk device corresponding to the business command according to the hard disk information in the header information;

[0058] The step is designed to achieve the hard disk device corresponding to the business command based on the header information. After the header information is parsed from the business command, the hard disk information can be extracted, which is the relevant information of the hard disk device corresponding to the business command, including but not limited to device number, function number, bus number, address information, etc. Thus, the hardware device identification can be realized according to the hardware information, and the hard disk device corresponding to the business command is determined.

[0059] S103: if the hard disk device is a preset acceleration hard disk, a binding identifier is added in the business command, so that the array card driver binds the array card where the preset acceleration hard disk is located with the CPU core corresponding to the array card according to the binding identifier, and executes the business command by using the CPU core.

[0060] The step is designed to achieve the business command binding of the preset acceleration hard disk. After the hard disk device corresponding to the business command is identified and determined, it is first judged whether the hard disk device is a preset acceleration hard disk, wherein the preset acceleration hard disk refers to a hard disk device in the array card that needs to exert maximum performance. It can be understood that the array card is a hard disk array composed of multiple hard disk devices, which can contain various types of hard disk devices, such as high-performance hard disks and ordinary hard disks. Here, the high-performance hard disk in the array card can be set as the preset acceleration hard disk, i.e., the high-performance hard disk in the array card is pre-specified to be accelerated in performance to exert its maximum performance.

[0061] Further, when the hard disk device corresponding to the service command is the preset accelerated hard disk, a binding identifier can be added in the service command. Thus, when the service command is sent to the array card to determine execution, the array card driver will read the binding identifier in the service command in the process of reading the service command. At this time, the current array card (i.e., the array card where the hard disk device is located) can be bound to the corresponding CPU core according to the binding identifier, so as to execute the service command by using the CPU core, thereby realizing service processing. Obviously, for the hard disk device in the array card that needs to be accelerated in performance, the binding identifier can be added in the corresponding service command to bind the array card to the corresponding CPU core, so that the service command can be executed by the CPU core corresponding to the array card, avoiding unnecessary link transmission, thereby realizing hard disk acceleration and exerting the maximum performance of the hard disk.

[0062] Conversely, when the hard disk device corresponding to the service command is not the preset accelerated hard disk, it is indicated that the hard disk device does not need to be accelerated in performance. At this time, the execution of the service command can be performed according to the conventional processing flow. It can be understood that, in this case, the CPU core for executing the service command can be any one of the CPU cores in the main device.

[0063] It can be seen that the service processing method provided by the embodiment of the present application adds the binding identifier to the service command corresponding to the hard disk (i.e., the preset accelerated hard disk) that needs to be accelerated in the array card by the array card firmware. Then, when the array card driver obtains the service command provided with the binding identifier, the array card can be bound to the corresponding CPU core first, and then the bound CPU core is used to execute the service command, thereby realizing service processing. Thus, all the service commands for the preset accelerated hard disk in the array card are bound to the CPU core, which can effectively avoid the long link of the CPU and the memory of the service command, thereby ensuring that the preset accelerated hard disk can exert the maximum performance. It can be seen that this implementation manner can exert the maximum performance of the hard disk in different application scenarios, and improve the usability of the array card where the hard disk is located.

[0064] In an embodiment of the present application, before the service command is parsed to obtain the header information when the service command is obtained, the following steps can also be included:

[0065] When the array card loading instruction is received, the topology structure of the array card is obtained;

[0066] Configuration information about the topology structure is obtained;

[0067] The preset accelerated hard disk is determined according to the configuration information.

[0068] The embodiment of the present application provides a method for determining a preset accelerated hard disk. Specifically, after the main device is started, the array card is normally loaded, at this time, the loading instruction of the array card is collected; further, when the array card loading instruction is received, the topology structure of the array card can be collected, which includes the topology information of the disk device, backplane device and the like under the corresponding array card, thereby, the topology structure can be output to the visual interface, so that the user can select the hard disk device in the array card which needs to be accelerated according to the actual demand, and generate the corresponding configuration information, of course, the configuration information includes the related information of the hard disk device specified by the user which needs to be accelerated, for specifying the corresponding hard disk device as a preset accelerated hard disk; finally, after obtaining the configuration information of the topology structure input by the user, the preset accelerated hard disk can be determined according to the configuration information.

[0069] In an embodiment of the present application, after the preset accelerated hard disk is determined according to the configuration information, the following steps can be further included:

[0070] When the topology structure is an Expander configuration structure or a Switch configuration structure, the ratio of the number of hard disks of the preset accelerated hard disk to the number of uplink is determined;

[0071] When the ratio is lower than a preset threshold, the uplink binding of the preset accelerated hard disk is performed.

[0072] The business processing method provided by the embodiment of the present application can further implement the binding operation of the uplink. Specifically, after determining that the specified hard disk device acceleration function is started, the topology structure of the array card can be acquired first, it can be understood that the topology structure of the array card can include a direct connection configuration structure, an Expander configuration structure, a Switch configuration structure and the like, wherein for the direct connection configuration structure, the uplink binding processing is not needed; for the Expander configuration structure or the Switch configuration structure, whether to perform the uplink binding processing can be determined according to the actual situation.

[0073] Therefore, when the topology structure is determined to be an Expander configuration structure or a Switch configuration structure, the number of preset accelerated hard disks in the array card can be determined first, then the ratio between the number and the number of uplink is calculated to obtain the ratio of the number of hard disks of the preset accelerated hard disk to the number of uplink; further, if the ratio is lower than a preset threshold, the uplink binding operation of the preset accelerated hard disk is performed, that is, the uplink is bound to only transmit the business command of the preset accelerated hard disk, otherwise, if the ratio is not lower than the preset threshold, in order to ensure the overall performance of the link, the uplink binding operation is not needed. The specific value of the preset threshold does not affect the implementation of the technical solution, which can be set by the technician according to the actual situation, and the present application does not limit it.

[0074] In an embodiment of the present application, the preset acceleration hard disk can be an NVMe hard disk and / or an SAS hard disk.

[0075] When the preset acceleration hard disk is an NVMe hard disk, the hard disk information is a hard disk device number.

[0076] When the preset acceleration hard disk is an SAS hard disk, the hard disk information is a hard disk address.

[0077] The embodiment of the present application provides a specific type of preset acceleration hard disk, such as the above-mentioned NVMe hard disk and / or SAS hard disk, that is, the NVMe hard disk and / or SAS hard disk in the array card can be specified to perform performance acceleration.

[0078] It should be noted that when the preset acceleration hard disk is an NVMe hard disk, the hard disk information is a hard disk device number, that is, the identification of the hard disk device can be realized according to the hard disk device number of the head information in the service command to determine whether it belongs to the NVMe hard disk that needs to perform performance acceleration; when the preset acceleration hard disk is an SAS hard disk, the hard disk information is a hard disk address, that is, the identification of the hard disk device can be realized according to the hard disk address of the head information in the service command to determine whether it belongs to the SAS hard disk that needs to perform performance acceleration.

[0079] The embodiment of the present application provides another service processing method.

[0080] Please refer to Figure 2 , Figure 2 The flowchart of another service processing method provided by the present application is shown in the figure, and the service processing method can include the following S201 and S204.

[0081] First of all, it should be noted that the service processing method provided by the embodiment of the present application is applied to the array card driver, that is, the implementation process of S201 and S204 is executed by the array card driver.

[0082] S201: obtaining a service command;

[0083] The purpose of this step is to realize the acquisition of the service command, that is, the received service command that needs to be executed, so as to realize the corresponding service processing. It should be noted that the service command is a service command that has been processed (here, the processing refers to setting a binding identifier or not setting a binding identifier) by the array card firmware in advance, so as to determine whether to perform the CPU kernel binding operation according to whether the binding identifier is contained in the service command in the process of executing the service command.

[0084] S202: judging whether the service command contains a binding identifier;

[0085] The step is designed to realize the binding identification judgment, i.e. judging whether the binding identification is contained in the service command. After the service command is acquired, the field analysis can be performed on the service command to determine whether the binding identification is contained, which is set by the array card firmware. Further, if the binding identification is contained in the service command, it indicates that the performance acceleration processing of the hard disk device corresponding to the service command is needed, i.e. the CPU core binding operation is needed; if the binding identification is not contained in the service command, it indicates that the performance acceleration processing of the hard disk device corresponding to the service command is not needed, i.e. the CPU core binding operation is not needed.

[0086] S203: If yes, the hard disk device corresponding to the service command is determined, and the array card where the hard disk device is located is bound with the CPU core corresponding to the array card according to the binding identification;

[0087] The step is designed to realize the CPU core binding operation. When it is determined that the binding identification is contained in the service command, the hard disk device corresponding to the service command can be determined, at this time, it indicates that the hard disk device is the hard disk device in the array card which needs to be accelerated in performance, i.e. the preset acceleration hard disk in the previous embodiment; further, the array card where the hard disk device is located is determined, and the array card is bound with the CPU core corresponding to the array card, so as to realize the CPU core binding operation. Thus, for the hard disk device in the array card which needs to be accelerated in performance, the binding of the array card and the corresponding CPU core is realized through the binding identification set in the corresponding service command. Of course, if the binding identification is not contained in the service command, the CPU core binding operation is not needed.

[0088] S204: The service command is executed by the CPU core.

[0089] The step is designed to realize the execution of the service command. After the array card where the hard disk device corresponding to the service command is located is bound with the CPU core corresponding to the array card, the service command can be directly executed by the bound CPU core. Obviously, since the CPU core binding operation is performed, the service command can be directly executed by the CPU core corresponding to the array card, avoiding the service command being distributed to other CPU cores for processing, and further avoiding unnecessary link transmission, so as to realize the hard disk acceleration and exert the maximum performance of the hard disk.

[0090] Of course, for the service command which is not set with the binding identification, the execution of the service command can be performed according to the conventional processing flow. It can be understood that in this case, the CPU core for executing the service command can be any one of the CPU cores in the main device.

[0091] It can be seen that the business processing method provided by the embodiment of the application adds a binding identifier to the business command corresponding to the hard disk (i.e., the preset accelerated hard disk) that needs to be accelerated in the array card through the array card firmware, and then when the array card driver obtains the business command provided with the binding identifier, the array card can be bound to the CPU core corresponding thereto first, and then the CPU core bound is used to execute the business command, so as to realize business processing. Therefore, all the business commands for the preset accelerated hard disk in the array card are bound to the CPU core, which can effectively avoid the business command from going through a long link of CPU and memory, so as to ensure that the preset accelerated hard disk performance is maximally exerted. It can be seen that this implementation manner can exert the maximum performance of the hard disk in different application scenarios, and improve the ease of use of the array card where the hard disk is located.

[0092] In an embodiment of the application, before the business command is obtained, the method can further include the following steps:

[0093] Obtaining PCIe information corresponding to the array card;

[0094] Extracting NUMA information from the PCIe information;

[0095] Obtaining CPU core information corresponding to the NUMA information in the CPU core list;

[0096] Determining the CPU core corresponding to the array card according to the CPU core information.

[0097] The embodiment of the application provides an implementation method for determining the CPU core corresponding to the array card, so that when the CPU core binding operation needs to be performed, the array card can be bound to the CPU core corresponding thereto. Specifically, after the device is powered on and the system is started, the system kernel loads the array card driver, the array card driver obtains PCIe related information to which the array card is allocated in the system, and can extract NUMA (Non Uniform Memory Access, non-uniform memory access) information therefrom. Then, the NUMA information is compared with the CPU core table, and the CPU core information corresponding to the NUMA information is determined, and the determination of the CPU core is realized. The CPU core table includes the related information of all CPU cores in the current device main body.

[0098] Further, the CPU core information corresponding to the array card obtained by the query can be saved, so that when the CPU core binding operation needs to be performed, the CPU core binding operation can be directly performed according to the CPU core information.

[0099] The embodiment of the application provides another business processing method.

[0100] The service processing method provided by the embodiment of the application can include the following steps:

[0101] (1) After the device main body is normally started, the array card is normally loaded, and the topology structure information of the disk, backboard and the like mounted under the array card can be acquired at the same time. In addition, an option is set in the array card firmware, which is used to select whether to perform acceleration processing on the hard disk device. Here, the function can be enabled by default for NVMe SSD and SAS SSD.

[0102] (2) After the high-performance disk acceleration function is enabled, the array card firmware first judges the topology structure of the array card. If it is a direct connection configuration, no special processing is performed on the link. If it is an Expander configuration or a Switch configuration, it is further judged whether the high-performance disk is greater than half of the maximum number of uplink (preset threshold). If it is less than half, link binding is performed on the high-performance disk, that is, the uplink is bound to only transmit the service command of the high-performance disk. If it is greater than half, the link is not bound for processing considering the overall link performance.

[0103] (3) After normally entering the system, the array card driver is loaded by the system kernel. The array card driver will acquire the PCIe related information allocated to the array card in the system, extract the NUMA of the array card therefrom, and compare it with the CPU core information of the CPU list (CPU core table) in the system. The CPU core information of the array card is stored in the array card driver for backup.

[0104] (4) For NVMe SSD, each NVMe SSD uses the same bus number (Bus Number) as the array card, and is provided with an independent device number (Device Number) and function number (Function Number). Subsequently, the array card firmware adds a specific prefix (the prefix is the binding identifier described above) to the transaction layer data message in the header of the transaction layer data message (that is, the service command) pointing to the Device Number of the NVMe SSD. Therefore, when the array card driver transmits the message, once the specific prefix is read, an operation of binding the CPU core of the array card is added. In this case, all service commands for the NVMe SSD are bound to the CPU core, and do not pass through the link of the far CPU and memory, so as to ensure that the performance of the NVMe SSD is maximized and is not affected by the CPU and memory resources.

[0105] (5) For SAS SSD, the array card firmware can first collect the SAS addresses of the SAS SSDs that need to be accelerated, and then add a special prefix to the commands in the Header of all business commands that point to these SAS addresses. In this way, when the array card driver transmits the business command, it will add an operation of binding the CPU core of the array card where the array card is located as soon as it reads the special prefix (the prefix is the binding identifier). In this case, all business commands for SAS SSDs are bound to CPU cores and do not go through the link of a far CPU and memory, thereby ensuring that the performance of SAS SSDs is maximized and is not affected by CPU and memory resources.

[0106] It can be seen that the business processing method provided by the embodiments of the application adds a binding identifier to the business command corresponding to the hard disk (i.e., the preset accelerated hard disk) that needs to be accelerated in the array card through the array card firmware, and then, when the array card driver obtains the business command with the binding identifier, the array card and the CPU core corresponding to the array card are bound first, and then the CPU core is used to execute the business command, thereby realizing business processing. In this way, all business commands for the preset accelerated hard disk in the array card are bound to the CPU core, which can effectively avoid the business command going through the link of a far CPU and memory, thereby ensuring that the performance of the preset accelerated hard disk is maximized. It can be seen that this implementation can maximize the performance of the hard disk in different application scenarios and improve the ease of use of the array card where the hard disk is located.

[0107] The embodiments of the application provide a business processing device.

[0108] Please refer to Figure 3 , Figure 3 The business processing device provided by the application has the structure shown in the figure and can be applied to an array card firmware, and includes:

[0109] The parsing module 1 is configured to parse the business command when the business command is obtained, and obtain the header information.

[0110] The determining module 2 is configured to determine the hard disk device corresponding to the business command according to the hard disk information in the header information.

[0111] The setting module 3 is configured to add a binding identifier in the business command if the hard disk device is a preset accelerated hard disk, so that the array card driver binds the array card where the preset accelerated hard disk is located to the CPU core corresponding to the array card according to the binding identifier, and executes the business command by using the CPU core.

[0112] It can be seen that the business processing device provided in the embodiment of the present application adds a binding identifier to the business command corresponding to the hard disk (i.e., the preset accelerated hard disk) that needs to be accelerated in the array card through the array card firmware, and then when the array card driver obtains the business command provided with the binding identifier, the array card can be bound to the CPU core corresponding thereto first, and then the CPU core bound is used to execute the business command, so as to realize business processing. Therefore, all the business commands for the preset accelerated hard disk in the array card are bound to the CPU core, which can effectively avoid the business command from going through a long link of CPU and memory, so as to ensure that the preset accelerated hard disk performance is maximally exerted. It can be seen that this implementation manner can exert the maximum performance of the hard disk in different application scenarios, and improve the usability of the array card where the hard disk is located.

[0113] In an embodiment of the present application, the business processing device can further include a preset accelerated hard disk determination module configured to, before obtaining the header information when the business command is obtained, obtain the topology structure of the array card when the array card loading instruction is received; obtain the configuration information about the topology structure; and determine the preset accelerated hard disk according to the configuration information.

[0114] In an embodiment of the present application, the business processing device can further include an uplink binding module configured to, after the preset accelerated hard disk is determined according to the configuration information, when the topology structure is an Expander configuration structure or a Switch configuration structure, determine the proportion of the number of hard disks of the preset accelerated hard disk to the number of uplinks; and when the proportion is lower than a preset threshold, bind the uplink to the preset accelerated hard disk.

[0115] In an embodiment of the present application, the preset accelerated hard disk can be an NVMe hard disk and / or an SAS hard disk; when the preset accelerated hard disk is an NVMe hard disk, the hard disk information is a hard disk device number; and when the preset accelerated hard disk is an SAS hard disk, the hard disk information is a hard disk address.
