目前，SCSI系统中可以查询硬盘信息、扩展卡地址、RAID卡等信息，但SCSI系统不支持RAID卡的管理配置。RAID卡用于向硬盘发送读写指令，必须配备相应的配置管理；否则，在RAID卡出现故障时，将难以准确诊断RAID卡问题所在。为此，本申请提供了一种RAID卡管理方案，能够在不增加硬件复杂性的前提下，实现了RAID卡的有效管理和配置。At present, the SCSI system can query hard disk information, expansion card address, RAID card and other information, but the SCSI system does not support the management and configuration of RAID cards. RAID cards are used to send read and write instructions to hard disks, and must be equipped with corresponding configuration management; otherwise, when a RAID card fails, it will be difficult to accurately diagnose the problem of the RAID card. To this end, the present application provides a RAID card management solution that can achieve effective management and configuration of RAID cards without increasing hardware complexity.
参见图1所示，本申请实施例公开了一种RAID卡管理系统，包括：读写接口模块、RAID卡管理模块、与读写接口模块和RAID卡管理模块连接的RAID卡驱动、以及与RAID卡驱动连接的RAID卡。RAID卡驱动与RAID卡之间的通信通道为PCIe（Peripheral ComponentInterconnect Express，一种高速串行通信互联标准）通道。As shown in FIG1 , the embodiment of the present application discloses a RAID card management system, including: a read-write interface module, a RAID card management module, a RAID card driver connected to the read-write interface module and the RAID card management module, and a RAID card connected to the RAID card driver. The communication channel between the RAID card driver and the RAID card is a PCIe (Peripheral Component Interconnect Express, a high-speed serial communication interconnection standard) channel.
其中，读写接口模块和RAID卡驱动通过第一通信通道连接，RAID卡管理模块和RAID卡驱动通过第二通信通道连接。The read/write interface module and the RAID card driver are connected via a first communication channel, and the RAID card management module and the RAID card driver are connected via a second communication channel.
其中，读写接口模块，用于通过第一通信通道和第一协议传输读写命令至RAID卡驱动，以使RAID卡驱动根据读写命令对RAID卡进行相应读写操作。The read/write interface module is used to transmit the read/write command to the RAID card driver through the first communication channel and the first protocol, so that the RAID card driver performs corresponding read/write operations on the RAID card according to the read/write command.
RAID卡管理模块，用于通过第二通信通道和第二协议传输管理命令至RAID卡驱动，以使RAID卡驱动根据管理命令对RAID卡进行相应管理操作。管理命令用于设置RAID卡的运行状态、使能RAID卡的端口、下载固件、模拟读写命令、模拟任务管理命令、配置RAID卡的参数和查询RAID卡的参数。具体可参见表1。The RAID card management module is used to transmit management commands to the RAID card driver through the second communication channel and the second protocol, so that the RAID card driver performs corresponding management operations on the RAID card according to the management commands. The management commands are used to set the operating status of the RAID card, enable the port of the RAID card, download firmware, simulate read and write commands, simulate task management commands, configure the parameters of the RAID card, and query the parameters of the RAID card. For details, please refer to Table 1.
表1Table 1
其中，设置RAID卡的运行状态记为：IOC_INIT；使能芯片端口记为：PORT_ENABLE；下载固件记为：FW_DOWNLOAD；模拟下发SCSI的IO命令记为：SCSI_IO_REQUEST；模拟下发任务管理命令记为：SCSI_TASK_MGMT；配置芯片参数记为：CONFIG；查询芯片参数记为：IOC_FACTS。Among them, setting the running status of the RAID card is recorded as: IOC_INIT; enabling the chip port is recorded as: PORT_ENABLE; downloading the firmware is recorded as: FW_DOWNLOAD; simulating the sending of SCSI IO commands is recorded as: SCSI_IO_REQUEST; simulating the sending of task management commands is recorded as: SCSI_TASK_MGMT; configuring chip parameters is recorded as: CONFIG; querying chip parameters is recorded as: IOC_FACTS.

其中，是否满足命令发送条件具体为：判断命令管理缓存池中是否存在未处理的命令。相应地，RAID卡驱动具体用于：判断命令管理缓存池中是否存在未处理的命令；若存在，则执行在命令管理缓存池中查询封装后管理命令，并将查询到的封装后管理命令发送至RAID卡的步骤。Whether the command sending condition is met is specifically: judging whether there are unprocessed commands in the command management buffer pool. Accordingly, the RAID card driver is specifically used to: judge whether there are unprocessed commands in the command management buffer pool; if there are, perform the steps of querying the encapsulated management command in the command management buffer pool, and sending the queried encapsulated management command to the RAID card.
在一种实施方式中，RAID卡驱动将查询到的封装后管理命令以DMA方式发送至RAID卡。也就是说：管理命令本身以DMA方式实现快速传输。In one implementation, the RAID card driver sends the queried packaged management command to the RAID card in DMA mode, that is, the management command itself is quickly transmitted in DMA mode.
在一种实施方式中，RAID卡驱动用于：为管理命令分配命令标识信息和用户编号；按照第二协议封装管理命令、命令标识信息和用户编号，得到封装后管理命令；封装后管理命令还包括：功能码、帧长度、帧偏移地址、预留字段和负载数据。第二协议可以为私有协议，在一种示例中，第二协议对于管理命令的帧格式定义可参照表2，对于响应消息的帧格式定义可参照表3。In one embodiment, the RAID card driver is used to: assign command identification information and a user number to the management command; encapsulate the management command, the command identification information and the user number according to the second protocol to obtain the encapsulated management command; the encapsulated management command also includes: a function code, a frame length, a frame offset address, a reserved field and load data. The second protocol can be a private protocol. In one example, the second protocol can refer to Table 2 for the frame format definition of the management command, and can refer to Table 3 for the frame format definition of the response message.
表2Table 2
表3table 3
需要说明的是，芯片状态为RAID卡的IOC的状态。封装后管理命令对应有相应的命令描述符。在一种实施方式中，RAID卡驱动用于：创建封装后管理命令的命令描述符；将命令描述符写入RAID卡中的寄存器；相应地，RAID卡用于：从寄存器读取命令描述符；根据命令描述符查询并处理封装后管理命令。It should be noted that the chip status is the status of the IOC of the RAID card. The post-encapsulation management command corresponds to a corresponding command descriptor. In one embodiment, the RAID card driver is used to: create a command descriptor for the post-encapsulation management command; write the command descriptor to the register in the RAID card; accordingly, the RAID card is used to: read the command descriptor from the register; query and process the post-encapsulation management command according to the command descriptor.
为了加快数据传输效率，本实施例中的RAID卡与RAID卡驱动通过DMA方式或RDMA方式进行数据交换。在一种实施方式中，RAID卡用于：发送封装后管理命令的响应消息至RAID卡驱动，并创建响应消息的响应描述符；将响应描述符写入RAID卡驱动的回复队列；相应地，RAID卡驱动用于：从回复队列读取响应描述符；根据响应描述符查询并处理响应消息。其中，RAID卡用于：以DMA方式发送封装后管理命令的响应消息至RAID卡驱动。In order to speed up data transmission efficiency, the RAID card in this embodiment exchanges data with the RAID card driver via DMA or RDMA. In one embodiment, the RAID card is used to: send a response message of the encapsulated management command to the RAID card driver, and create a response descriptor of the response message; write the response descriptor to the reply queue of the RAID card driver; accordingly, the RAID card driver is used to: read the response descriptor from the reply queue; query and process the response message according to the response descriptor. Among them, the RAID card is used to: send the response message of the encapsulated management command to the RAID card driver via DMA.
在一种实施方式中，RAID卡驱动用于：将响应消息暂存至预设的响应管理缓存池；若满足响应处理条件，则根据响应描述符在响应管理缓存池中查询响应消息，并将查询到的响应消息通过第二通信通道以DMA方式发送至RAID卡管理模块；相应地，RAID卡管理模块用于：若响应消息为成功响应消息，则根据响应消息中的用户编号，将响应消息发送至相应用户端。In one embodiment, the RAID card driver is used to: temporarily store the response message in a preset response management buffer pool; if the response processing conditions are met, query the response message in the response management buffer pool according to the response descriptor, and send the queried response message to the RAID card management module through the second communication channel in DMA mode; accordingly, the RAID card management module is used to: if the response message is a successful response message, send the response message to the corresponding user end according to the user number in the response message.
相应地，RAID卡驱动在确定响应消息响应超时或未接收到响应消息时，重启响应消息的发送设备；在一种示例中，发送设备为RAID卡、RAID卡连接的扩展芯片和/或扩展芯片连接的硬盘。Accordingly, when the RAID card driver determines that the response message has timed out or has not received the response message, it restarts the device sending the response message; in one example, the sending device is a RAID card, an expansion chip connected to the RAID card, and/or a hard disk connected to the expansion chip.
在一种实施方式中，RAID卡用于：若响应消息为失败响应消息，则从无应答队列获取系统应答消息帧地址；以DMA方式将响应消息写入系统应答消息帧地址；将系统应答消息帧地址写入响应描述符。In one embodiment, the RAID card is used to: if the response message is a failure response message, obtain the system response message frame address from the no response queue; write the response message to the system response message frame address in DMA mode; write the system response message frame address into the response descriptor.
在一种实施方式中，RAID卡连接有至少一个扩展芯片，至少一个扩展芯片连接有至少一个硬盘。In one implementation, the RAID card is connected to at least one expansion chip, and the at least one expansion chip is connected to at least one hard disk.
可见，本实施例中，读写接口模块和RAID卡管理模块分别有自己独立的通信通道，即：第一通信通道和第二通信通道，第一通信通道以第一协议传输读写命令给RAID卡驱动，而第二通信通道以第二协议传输管理命令给RAID卡驱动，由此实现了读写操作和管理操作的独立传输；并且，读写接口模块和RAID卡管理模块共用RAID卡驱动至RAID卡的PCIe通道，在不增加硬件复杂性的前提下，实现了RAID卡的有效管理。It can be seen that in this embodiment, the read-write interface module and the RAID card management module each have their own independent communication channels, namely: a first communication channel and a second communication channel. The first communication channel transmits read-write commands to the RAID card driver using a first protocol, while the second communication channel transmits management commands to the RAID card driver using a second protocol, thereby realizing independent transmission of read-write operations and management operations; and, the read-write interface module and the RAID card management module share the PCIe channel from the RAID card driver to the RAID card, thereby realizing effective management of the RAID card without increasing the complexity of the hardware.

在一种实施方式中，RAID卡用于：发送封装后管理命令的响应消息至RAID卡驱动，并创建响应消息的响应描述符；将响应描述符写入RAID卡驱动的回复队列；相应地，RAID卡驱动用于：从回复队列读取响应描述符；根据响应描述符查询并处理响应消息。In one embodiment, the RAID card is used to: send a response message of the encapsulated management command to the RAID card driver, and create a response descriptor for the response message; write the response descriptor to a reply queue of the RAID card driver; accordingly, the RAID card driver is used to: read the response descriptor from the reply queue; query and process the response message according to the response descriptor.
在一种实施方式中，RAID卡用于：以DMA方式发送封装后管理命令的响应消息至RAID卡驱动。In one implementation, the RAID card is used to send a response message of the encapsulated management command to the RAID card driver in a DMA manner.
在一种实施方式中，RAID卡用于：将响应消息暂存至预设的响应管理缓存池；若满足响应处理条件，则根据响应描述符在响应管理缓存池中查询响应消息，并将查询到的响应消息通过第二通信通道以DMA方式发送至RAID卡管理模块；相应地，RAID卡管理模块用于：若响应消息为成功响应消息，则根据响应消息中的用户编号，将响应消息发送至相应用户端。In one embodiment, the RAID card is used to: temporarily store the response message in a preset response management buffer pool; if the response processing conditions are met, query the response message in the response management buffer pool according to the response descriptor, and send the queried response message to the RAID card management module through the second communication channel in DMA mode; accordingly, the RAID card management module is used to: if the response message is a successful response message, send the response message to the corresponding user end according to the user number in the response message.
在一种实施方式中，RAID卡驱动具体用于：若响应消息响应超时或未接收到响应消息，则重启响应消息的发送设备；发送设备为RAID卡、RAID卡连接的扩展芯片和/或扩展芯片连接的硬盘。In one embodiment, the RAID card driver is specifically used to: restart the sending device of the response message if the response message times out or no response message is received; the sending device is a RAID card, an expansion chip connected to the RAID card and/or a hard disk connected to the expansion chip.
在一种实施方式中，RAID卡用于：若响应消息为失败响应消息，则从无应答队列获取系统应答消息帧地址；以DMA方式将响应消息写入系统应答消息帧地址；将系统应答消息帧地址写入响应描述符。In one embodiment, the RAID card is used to: if the response message is a failure response message, obtain the system response message frame address from the no response queue; write the response message to the system response message frame address in DMA mode; write the system response message frame address into the response descriptor.
在一种实施方式中，管理命令用于设置RAID卡的运行状态、使能RAID卡的端口、下载固件、模拟读写命令、模拟任务管理命令、配置RAID卡的参数和查询RAID卡的参数。In one embodiment, the management command is used to set the operating status of the RAID card, enable the port of the RAID card, download firmware, simulate read and write commands, simulate task management commands, configure RAID card parameters, and query RAID card parameters.
在一种实施方式中，RAID卡连接有至少一个扩展芯片，至少一个扩展芯片连接有至少一个硬盘。In one implementation, the RAID card is connected to at least one expansion chip, and the at least one expansion chip is connected to at least one hard disk.
可见，本实施例中，读写接口模块和RAID卡管理模块分别有自己独立的通信通道，即：第一通信通道和第二通信通道，第一通信通道以第一协议传输读写命令给RAID卡驱动，而第二通信通道以第二协议传输管理命令给RAID卡驱动，由此实现了读写操作和管理操作的独立传输；并且，读写接口模块和RAID卡管理模块共用RAID卡驱动至RAID卡的PCIe通道，在不增加硬件复杂性的前提下，实现了RAID卡的有效管理。It can be seen that in this embodiment, the read-write interface module and the RAID card management module each have their own independent communication channels, namely: a first communication channel and a second communication channel. The first communication channel transmits read-write commands to the RAID card driver using a first protocol, while the second communication channel transmits management commands to the RAID card driver using a second protocol, thereby realizing independent transmission of read-write operations and management operations; and, the read-write interface module and the RAID card management module share the PCIe channel from the RAID card driver to the RAID card, thereby realizing effective management of the RAID card without increasing the complexity of the hardware.
请参见图2，在RAID卡驱动模块中构建RAID卡驱动时设立两条独立通道，分别处理SCSI命令和管理命令。其中一条通道专注于SCSI系统与RAID卡之间的IO命令交互，而另一条则专门用于管理模块与RAID卡之间的管理命令沟通。这种设计能够确保管理命令执行的清晰度和效率，优化了整体性能。Please refer to Figure 2. When building the RAID card driver in the RAID card driver module, two independent channels are set up to process SCSI commands and management commands respectively. One channel is dedicated to the IO command interaction between the SCSI system and the RAID card, while the other is dedicated to the management command communication between the management module and the RAID card. This design can ensure the clarity and efficiency of the management command execution and optimize the overall performance.
其中，管理模块可借此专用管理通道发送并接收管理信息。同时，明确用户所需查询与设置的RAID卡管理信息及其帧格式，最终实现高效的信息交互流程。The management module can use this dedicated management channel to send and receive management information. At the same time, it can clarify the RAID card management information and its frame format that the user needs to query and set, and finally realize an efficient information exchange process.
具体的，管理模块中实现的功能包括：Specifically, the functions implemented in the management module include:
（1）获取用户的管理命令请求。(1) Obtain the user's management command request.
（2）根据用户需求组织和RAID卡交互的帧格式，然后把组织完成的帧格式下发给RAID卡固件。(2) Organize the frame format for interaction with the RAID card according to user requirements, and then send the organized frame format to the RAID card firmware.
（3）调用RAID卡驱动提供的接口，把命令情况放到管理命令请求的内存缓存中。(3) Call the interface provided by the RAID card driver and put the command status into the memory cache of the management command request.
（4）等待RAID卡/IOC的命令返回信息，根据返回信息进行解析，回显给用户。IOC（IO Controller）为RAID卡芯片。(4) Wait for the command return information from the RAID card/IOC, parse the returned information, and display it back to the user. IOC (IO Controller) is the RAID card chip.
RAID卡驱动中实现的功能包括：The functions implemented in the RAID card driver include:
（1）创建管理模块请求命令的缓存池、命令返回的缓存池，管理模块接收到用户请求后，把请求命令放到命令请求的内存缓存池中，RAID卡/IOC返回的命令返回放到命令返回的缓存池。(1) Create a cache pool for management module request commands and a cache pool for command returns. After receiving a user request, the management module puts the request command into the memory cache pool for command requests and puts the command returned by the RAID card/IOC into the cache pool for command returns.
（2）为每个使用该通道的用户起一个ID；在多用户同时使用该通道进行数据交互的时候，可以通过用户ID判断是哪个用户下发命令。进而把返回的数据返回给对应的用户。(2) Give each user who uses the channel an ID; when multiple users use the channel to interact with data at the same time, the user ID can be used to determine which user issued the command. Then the returned data is returned to the corresponding user.
（3）判断缓存池中是否有请求命令，如果存在请求命令，把请求命令发送给RAID卡/IOC。(3) Determine whether there is a request command in the cache pool. If there is a request command, send the request command to the RAID card/IOC.
（4）接收RAID卡/IOC的发送来的命令返回信息，并把返回信息放内存缓存池中。(4) Receive the command return information sent by the RAID card/IOC and put the return information into the memory buffer pool.
（5）解析命令返回信息，根据用户ID，返回对应的用户。(5) Parse the command return information and return the corresponding user based on the user ID.
（6）专门开启一个线程由于检测交互命令超时，在用户把命令下发给RAID卡时候，RAID卡驱动需要记录下发的每条命令的时间，在检测命令错误线程中，检测命令是否在规定时间返回。(6) A special thread is opened to detect interactive command timeouts. When the user sends a command to the RAID card, the RAID card driver needs to record the time of each command sent. In the command error detection thread, it is checked whether the command returns within the specified time.
其中，如果指令正常返回，把指令从异常线程缓存中删除；如果指令超时返回，进行异常指令的修复；异常指令的修复策略：重启对应指令的设备（硬盘、扩展芯片等）。Among them, if the instruction returns normally, the instruction is deleted from the abnormal thread cache; if the instruction returns with a timeout, the abnormal instruction is repaired; the repair strategy for the abnormal instruction is: restart the device corresponding to the instruction (hard disk, expansion chip, etc.).
RAID卡/IOC中实现的功能包括：The functions implemented in the RAID card/IOC include:
（1）接收RAID卡驱动下发的指令，并且解析对应的指令。(1) Receive instructions from the RAID card driver and parse the corresponding instructions.
（2）根据接收的指令，返回对应的信息。(2) Return corresponding information according to the received instructions.
管理模块、RAID驱动和RAID卡/IOC之间的交互可参照图3，图3中的标号表示执行顺序。具体过程包括：The interaction between the management module, RAID driver and RAID card/IOC can be seen in Figure 3, where the numbers in Figure 3 represent the execution order. The specific process includes:
（1）RAID卡管理模块程序接收来自用户的请求。(1) The RAID card management module program receives requests from users.
（2）RAID卡驱动程序从其未使用的帧池中分配系统请求消息帧（具体分配命令的ID、用户的ID等），并构建指令帧内的请求消息（即负载）。(2) The RAID card driver allocates a system request message frame (specifically allocates the command ID, user ID, etc.) from its unused frame pool and constructs the request message (i.e., payload) within the command frame.
（3）RAID卡驱动程序创建指令帧请求描述符（请求的描述符）。描述符用于取真正的数据。(3) The RAID card driver creates a command frame request descriptor (request descriptor). The descriptor is used to retrieve the actual data.
（4）RAID卡驱动程序将请求描述符写入寄存器。其中，用户获得在I/O的持续时间内的系统请求消息帧的所有权。(4) The RAID card driver writes the request descriptor into the register, where the user obtains ownership of the system request message frame for the duration of the I/O.
（5）RAID卡/IOC主要的任务包括：(5) The main tasks of the RAID card/IOC include:
a、从请求描述符后队列中读取描述符。a. Read the descriptor from the queue after the request descriptor.
b、使用DMA将请求消息拉到本地消息帧。b. Use DMA to pull the request message to the local message frame.
（6）RAID卡/IOC根据DevHandle处理请求消息并将I/O发送到目标。(6) The RAID card/IOC processes the request message according to the DevHandle and sends the I/O to the target.
（7）RAID卡/IOC收到目标的答复。(7) The RAID card/IOC receives a response from the target.
（8）如果I/O状态为成功，RAID卡/IOC将写入指令成功应答描述符写入中断，其中包含来自请求描述符发送到位于主机驱动程序内存中的回复描述符后队列，并生成系统中断。此时，RAID卡驱动程序重新获得系统请求消息帧的所有权。具体的数据以DMA方式传输。(8) If the I/O status is successful, the RAID card/IOC writes the write command success response descriptor to the interrupt, which contains the reply descriptor queue from the request descriptor to the host driver memory, and generates a system interrupt. At this time, the RAID card driver regains ownership of the system request message frame. The specific data is transferred in DMA mode.
（9）如果输入/输出状态不成功，IOC将执行以下操作，包括：(9) If the input/output status is unsuccessful, the IOC will perform the following operations, including:
a、从无应答队列（未响应超时的命令）中弹出系统应答消息帧地址。a. Pop up the system response message frame address from the no-response queue (commands that have not responded to the timeout).
b、使用DMA将指令错误回复消息传输到系统回复消息帧。b. Use DMA to transfer the command error reply message to the system reply message frame.
c、写入地址应答描述符，其中包含系统应答消息帧地址和SMID值从请求描述符到位于主机驱动程序内存中的回复描述符后队列，并生成系统中断。此时，RAID卡驱动程序重新获得系统请求消息帧的所有权。c. Write the address response descriptor, which contains the system response message frame address and SMID value from the request descriptor to the reply descriptor queue located in the host driver's memory, and generate a system interrupt. At this point, the RAID card driver regains ownership of the system request message frame.
（10）主机驱动程序处理中断并从应答描述符后队列中读取新条目。之后读取描述符时，主机驱动程序会将其标记为未使用。(10) The host driver processes the interrupt and reads a new entry from the reply descriptor back queue. When the descriptor is read thereafter, the host driver marks it as unused.
（11）RAID卡驱动程序更新其回复描述符后队列头索引，并将此新值（新的描述符）写入回复后主机索引寄存器（其中包括存描述符的队列）。(11) The RAID card driver updates its reply descriptor post-queue head index and writes this new value (new descriptor) to the reply post-host index register (which includes the queue where the descriptor is stored).
（12）如果在步骤（9）中使用了系统应答消息帧，则主机驱动程序执行以下操作，包括：a.将SRMFA（回复的数据）写入无应答队列的尾部条目，并更新其尾部索引。b.将此新索引值写入“无应答主机索引”寄存器。这使得系统回复消息帧再次可供RAID卡/IOC使用。(12) If the system reply message frame was used in step (9), the host driver performs the following operations, including: a. Writing SRMFA (the data of the reply) to the tail entry of the no reply queue and updating its tail index. b. Writing this new index value to the "no reply host index" register. This makes the system reply message frame available to the RAID card/IOC again.
（13）RAID卡驱动程序向操作系统发送完成状态，以进行I/O操作。(13) The RAID card driver sends a completion status to the operating system to perform the I/O operation.
可见，本实施例在RAID卡驱动模块单独构造一个路径和RAID卡进行传输数据，交互自定义私有的管理命令（如表1、表2和表3所示），实现对RAID卡信息的查询或者设置。但在管理命令和IO命令经过RAID卡驱动模块后，管理命令和IO命令共用PCIe通道和RAID卡进行传输数据。RAID卡固件接收到驱动传输的命令，RAID卡固件进行解析命令，然后根据解析得到的功能码，执行相应的命令。It can be seen that in this embodiment, a path is constructed separately in the RAID card driver module to transmit data with the RAID card, and private management commands are interactively customized (as shown in Table 1, Table 2 and Table 3) to query or set the RAID card information. However, after the management command and the IO command pass through the RAID card driver module, the management command and the IO command share the PCIe channel and the RAID card to transmit data. The RAID card firmware receives the command transmitted by the driver, parses the command, and then executes the corresponding command according to the function code obtained by the parsing.
