Description

Technical Field

[0001] The present specification relates to the field of communication technology, and in particular to a device type identification method, apparatus, device, and readable storage medium. Background Art

[0002] As the core device for data processing and storage, servers play a vital role in enterprise-level applications. In order to meet the needs of different application scenarios, the internal configuration of modern server systems has become increasingly complex and diverse, especially the configuration of storage subsystems. SAS (Serial Attached SCSI) and SATA (Serial Advanced Technology Attachment) hard disk devices are widely used due to their excellent performance and high cost-effectiveness. However, the efficient operation of these devices depends on the matching storage controllers, such as RAID cards, PCH (Platform Controller Hub), and EXP (Expander) expansion chips.

[0003] In the current server architecture, the high-speed signals of SATA hard drives can come from a variety of different SATA controllers. For example, RAID cards enhance data security by providing redundancy mechanisms; PCH is usually integrated on the motherboard and is responsible for handling low-speed I / O operations and some SATA port controls; and EXP expansion chips are used to increase the number of SATA ports to support more storage device connections. Each controller has unique features and function sets, which means that for hard drives in the same physical location, different configuration rules may be required depending on the type of controller connected. In this case, if the actual controller type used is not correctly identified, it may cause configuration errors, which in turn affects the stability and performance of the entire server system.

[0004] In traditional methods, the identification of SATA controller types mainly relies on manual settings or preset fixed configuration modes, which is not only time-consuming and labor-intensive, but also prone to human errors. Especially in large-scale data center environments, when faced with hundreds or thousands of servers, the workload of manual configuration is huge and the maintenance cost is high. In addition, due to the lack of an effective automatic identification mechanism, when the hardware configuration changes, manual intervention is often required to ensure that the new configuration can correctly reflect the actual status. This not only increases the workload of operation and maintenance personnel, but may also cause business interruptions due to response delays, causing economic losses and social impacts to users.

These terms are only used to distinguish the same type of information from each other.

Depending on the context, in addition, the word "if" used may be interpreted as "at the time of" or "when" or "in response to determining".

[0034] As the core component of the data center, the performance and stability of the server are crucial to the operation of the entire information system. The complexity of server configuration increases with the development of technology, especially in storage systems. SAS (Serial Attached SCSI) and SATA (Serial Advanced Technology Attachment) hard disks are the main storage media for servers, and the complexity of their configuration and management directly affects the performance and reliability of the server.

[0035] In a server configuration, the configuration rules of SAS / SATA hard disk devices vary depending on the application scenario. In the server, the high-speed SATA signal of the SATA hard disk may come from a variety of SATA controllers, such as RAID storage cards, PCH (Platform Controller Hub) or EXP (Expander) expansion chips. These different controllers lead to different configuration requirements, and the reading sources of hard disk information are also different, and the slot numbers of hard disks are also different. This diversity and complexity increases the difficulty of software design and the error rate. Once the configuration is wrong, it may cause abnormal server function or even downtime, causing suspension of customer business and causing huge economic and social losses.

[0036] With the diversification of server configurations, traditional manual configuration methods have been unable to meet the rapidly changing market needs. Automated and intelligent configuration recognition technology has become the key to solving this problem. However, existing technical solutions are often unable to accurately identify and configure complex configurations of multiple SAS / SATA and multiple controllers, resulting in a high configuration error rate and overly complex software design.

[0037] Due to the differences in signals and configuration rules of different controllers, traditional configuration identification methods are prone to errors when faced with complex configurations. As server configurations become more diverse, software needs to process more logic and rules, increasing the complexity of the design.

[0038] This specification aims to provide a server SATA controller type identification solution that can be quickly adapted, highly adaptable, and highly stable. This solution needs to be able to cope with various complex configuration application scenarios of servers, such as multi-SAS / SATA with multi-controller configuration, reduce the complexity of software design, improve the accuracy and efficiency of configuration analysis and allocation, have adaptability and wide applicability, and save manpower and material costs.

[0039] The specific technical solution is described below.

[0040] In one embodiment, the present specification provides a device type identification method, which is applied to a BMC device of a server, and the method includes: obtaining electrical signal information from a backplane CPLD of a backplane through an I2C channel, wherein the electrical signal information is electrical signal information of a specified signal channel in a sideband signal connected to the backplane obtained by the backplane CPLD; judging the device type of hardware currently connected to the backplane according to the electrical signal information; the electrical signal information is generated according to level information generated by the hardware currently connected to the backplane in a preset manner.

[0041] Specifically, Figure 1 , including the following steps:

[0042] Step S11, obtaining electrical signal information from the backplane CPLD of the backplane through the I2C channel.

[0043] Step S12: determining the device type of the hardware currently connected to the backplane according to the electrical signal information.

[0044] In the backplane of the server, the CPLD is responsible for processing and transmitting the sideband signal from the SATA cable connector. The sideband signal is an additional signal channel used to transmit information such as the controller type. In this embodiment, the backplane CPLD obtains electrical signal information through a specified signal channel (such as the CTRL_TYPE signal) in the sideband signal. These signal information include but are not limited to the level, frequency, etc., which are generated by the hardware devices connected to the backplane (such as PCH, RAID card, EXP expansion chip, etc.) according to a preset method.

[0045] After CPLD obtains the electrical signal information, it transmits the information to BMC through I2C channel. I2C is a commonly used serial communication protocol suitable for communication between microcontrollers and various peripheral devices. In this solution, I2C channel provides an efficient and reliable communication method, enabling BMC to obtain electrical signal information from CPLD.

[0046] After receiving the electrical signal information, the BMC determines the type of hardware device currently connected to the backplane according to the preset level information recognition rules. For example, if the CTRL_TYPE signal is low, the BMC can determine that the current connection is a RAID card; if the signal is a 16Hz square wave, it may be a PCH controller; if it is a 4Hz square wave, it may be an EXP expansion chip.

[0047] Assume that a RAID card is connected to the server backplane via a SATA cable. The RAID card outputs a low level in the CTRL_TYPE signal channel according to the SFF-8485 protocol specification. After the backplane CPLD detects this low level signal, it passes this information to the BMC through the I2C channel. The BMC determines that the backplane is currently connected to the RAID card based on the low level signal. Then the BMC can obtain the hard disk information from the RAID card controller and display it on the out-of-band management monitoring interface for easy viewing and management by users.

[0048] Through this device type identification method, the server can automatically identify the type of connected SATA controller, thereby simplifying the configuration process, reducing human errors, and improving the stability and reliability of the server. This method is not only applicable to RAID cards, but can also be extended to other types of SATA controllers, such as PCH and EXP expansion chips, with wide applicability and flexibility.

[0049] In one implementation, the electrical signal information is derived from a specific sideband signal channel on a cable connector connected to the backplane, specifically a CTRL_TYPE signal.

[0050] The CTRL_TYPE signal presents different level states or waveforms under different types of SATA controllers. When the backplane is connected to the PCH, the motherboard CPLD outputs a 16Hz square wave as the CTRL_TYPE signal; when connected to the RAID card, the signal remains at a low level; and when the EXP expansion chip is used, a 4Hz square wave is output. The backplane CPLD, BP_CPLD, will continuously monitor and record the state changes of the CTRL_TYPE signal, and send this information to the BMC for processing through the I2C interface.

[0051] After receiving the electrical signal data transmitted by BP_CPLD, BMC uses a preset parsing algorithm to determine the specific SATA controller type. This step is based on the understanding of the CTRL_TYPE signal pattern generated by different controllers.

[0052] If the received data indicates that the CTRL_TYPE signal is in a low level state, the BMC can determine that the currently used SATA controller is a RAID card. If a 16Hz square wave is detected, it indicates that the controller is a PCH; and a 4Hz square wave corresponds to an EXP expansion chip.

[0053] For example, in a data center environment, operation and maintenance personnel need to quickly deploy multiple new servers. By adopting the solution provided by this implementation, each server can automatically identify the configuration of its storage subsystem and complete the correct settings without manual intervention, greatly improving deployment efficiency and accuracy.

[0054] To ensure that the CTRL_TYPE signal is transmitted accurately, the entire link includes a series of hardware components from the SATA controller to the backplane to the BMC, such as pull-up resistors, CPLD, etc., which work together to maintain signal integrity. Even when the SATA controller is replaced or upgraded in the future, as long as the new controller follows the same signal standard, the system can be seamlessly compatible and continue to provide reliable device type identification services.

[0055] In summary, this device type identification method not only simplifies the management process of the server storage subsystem, but also enhances the flexibility of the overall architecture, which is particularly important for large-scale data centers.

[0058] like Figure 2 , a pull-up resistor is designed on the CTRL_TYPE signal link on the backplane side to make its default state high.

[0059] In one implementation, the level information includes a low level, and the backplane CPLD obtains electrical signal information generated in response to the low level received by a designated signal channel in a sideband signal connected to the backplane, and the low level is output by the RAID card controller according to a designated protocol.

[0062] like Figure 4 , the PCH controller connects the high-speed cable to the backplane, the PCH only outputs high-speed signals, the CTRL_TYPE signal is output by the mainboard CPLD, and the MB_CPLD outputs a 16Hz square wave; Figure 5 The EXP controller is connected to the backplane with a high-speed cable. The EXP expansion board is also equipped with a CPLD chip. The CTRL_TYPE signal is controlled and output by the EXP CPLD and is a 4Hz square wave.
