Description

Technical Field

[0002] An NVMe (non-volatile memory express) device is a storage device using the NVMe interface specification, including SSD (Solid State Drive), SDI (Service Driven Infrastucture) card, etc.

[0003] A BMC (Baseboard Management Controller) is usually an independent board card installed on the server motherboard, providing support for IPMI (Intelligent Platform Management Interface) commands. During operation, all IPMI functions are completed by sending commands to the BMC. The commands use the instructions specified in the IPMI specification. The BMC receives and records event messages in the system event log, and maintains a sensor data record describing the situation of sensors in the system.

[0004] In a traditional server, the BMC accesses the NVMe device through physical buses such as I2C (Inter-Integrated Circuit) and PCIe (Peripheral Component Interconnect express) in response to IPMI commands, so as to obtain information such as the manufacturer, temperature, and voltage of the NVMe device, and perform operations such as upgrading the NVMe device.

[0059] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] Due to the high coupling between the server's BMC and NVMe devices, the system operation efficiency will be reduced to a certain extent, and when the NVMe device is upgraded, the BMC also needs to be upgraded accordingly, affecting the system stability. Therefore, one of the core concepts of the embodiment of the present invention is to develop a transparent transmission command word for upgrading, open up the link between the host computer software and the NVMe device, and the host computer can use the transparent transmission command word to upgrade the NVMe device connected to the BMC, so that after the NVMe device is upgraded, there is no need to adapt and upgrade the BMC, shorten the development cycle, and improve the stability of the server.

[0061] Reference Figure 1 , shows a flow chart of the steps of a device upgrade method provided by an embodiment of the present invention, which is applied to a server, the server includes a non-volatile storage fast channel NVMe device, an NVMe controller, and a baseboard management controller BMC, and the server communicates with a host computer. The method may specifically include the following steps:

[0062] Step 101, receiving a first transparent transmission command message sent by a host computer through the BMC, the first transparent transmission command message including: a driver type of an NVMe controller, an identifier of an NVMe controller, a transparent transmission command word, and a target upgrade data packet; the transparent transmission command word is used to instruct the BMC not to parse the target upgrade data packet.

[0063] When the NVMe device needs to be upgraded, a first transparent transmission command message can be generated by the host computer, and the first transparent transmission command message can be a message based on the IPMI protocol. The first transparent transmission command message may include the driver type of the NVMe controller, the identifier of the NVMe controller, the transparent transmission command word, and the target upgrade data packet. Among them, the target upgrade data packet is a partial or complete upgrade data packet corresponding to the NVMe device; the transparent transmission command word is a command word designed based on the IPMI protocol, and the command word is used to instruct the BMC to stop parsing when receiving the first transparent transmission command message and parsing the first transparent transmission command message. That is, the payload-target upgrade data packet after the transparent transmission command word is not parsed.

[0064] After the host computer generates the first transparent transmission command message, it sends the first transparent transmission command message to the BMC of the same server as the NVMe device that needs to be upgraded. The first transparent transmission command message can be sent to the BMC according to the IP address of the BMC.

[0065] The BMC receives the first passthrough command message, parses the first passthrough command message, and obtains the driver type of the NVMe controller and the identifier of the NVMe controller. When the BMC parses the passthrough command word, it stops parsing the content after the passthrough command word, that is, it stops parsing the target upgrade data packet after the passthrough command word.

[0066] Step 102: The BMC parses the first passthrough command message and encapsulates the first passthrough command message according to the driver type of the NVMe controller to obtain a second passthrough command message.

[0067] After receiving the first passthrough command message, the BMC parses the first passthrough command message and can obtain the driver type of the NVMe controller. The BMC can encapsulate the first passthrough command message according to the driver type of the NVMe controller, encapsulate the first passthrough command message into a driver format corresponding to the driver type of the NVMe controller, and obtain a second passthrough command message.

[0068] Step 103: The BMC sends the second passthrough command message to the NVMe controller according to the identifier of the NVMe controller.

[0069] After receiving the first passthrough command message, the BMC parses the first passthrough command message and can obtain the identifier of the NVMe controller. The BMC can send the second passthrough command message to the corresponding NVMe controller according to the identifier of the NVMe controller.

[0070] Step 104: The NVMe controller sends the target upgrade data packet to the NVMe device and triggers the NVMe device upgrade.

[0071] The NVMe controller receives the second passthrough command message, parses the second passthrough command message, and obtains the passthrough command word and the target upgrade data packet. The NVMe controller sends the target upgrade data packet to the NVMe device and triggers the NVMe device upgrade.

[0072] In an embodiment of the present invention, the BMC receives a first passthrough command message sent by the host computer. The first passthrough command message includes: the driver type of the NVMe controller, the identifier of the NVMe controller, the passthrough command word, and the target upgrade data packet. The passthrough command word is used to instruct the BMC not to parse the target upgrade data packet. The BMC parses the first passthrough command message and encapsulates the first passthrough command message according to the driver type of the NVMe controller to obtain a second passthrough command message. The BMC sends the second passthrough command message to the NVMe controller according to the identifier of the NVMe controller. The NVMe controller sends the target upgrade data packet to the NVMe device and triggers the upgrade of the NVMe device. This method can reduce the coupling degree between the BMC and the NVMe device and improve the operation efficiency of the server system. Moreover, after the NVMe device is upgraded, there is no need to develop and upgrade the BMC adaptively. Only the upgrade program of the host computer needs to be updated correspondingly. Therefore, the development cycle can be shortened. At the same time, reducing the upgrade of the BMC can also ensure the stability and reliability of the server.

[0073] In one embodiment, the passthrough command word is further used to instruct the NVMe controller to upgrade the NVMe device. The NVMe controller sends the target upgrade data packet to the NVMe device and triggers the upgrade of the NVMe device, including:

[0074] The NVMe controller receives and parses the second passthrough command message to obtain the passthrough command word and the target upgrade data packet;

[0075] The NVMe controller sends the target upgrade data packet to the NVMe device and triggers the upgrade of the NVMe device according to the passthrough command word.

[0076] The NVMe controller receives the second passthrough command message and parses the second passthrough command message to obtain the passthrough command word and the target upgrade data packet. The passthrough command word is used to instruct the NVMe controller to upgrade the NVMe device. Therefore, when the NVMe controller parses the passthrough command word, it immediately sends the target upgrade data packet to the NVMe device. After the target upgrade data packet is sent, the NVMe controller triggers the upgrade of the NVMe device.

[0077] In an embodiment of the present invention, when the BMC parses the pass-through command word, it stops parsing the target upgrade data packet after the pass-through command word. When the NVMe controller parses the pass-through command word, it sends the target upgrade data to the NVMe device and triggers the upgrade of the NVMe device. Through the pass-through command word, while decoupling some management functions of the BMC for the NVMe device, the upgrade of the NVMe device can be achieved. Through the data pass-through function, the data packets in all packets generated based on the pass-through command word can be passed through the BMC to the NVMe controller, realizing direct data interaction between the host computer software and the NVMe device.

[0078] In one embodiment, the first pass-through command message further includes an upgrade command for instructing the NVMe controller to upgrade the NVMe device. Through the NVMe controller, the target upgrade data packet is sent to the NVMe device and the upgrade of the NVMe device is triggered, including:

[0079] Receiving and parsing the second pass-through command message by the NVMe controller to obtain the upgrade command and the target upgrade data packet;

[0080] Through the NVMe controller, the target upgrade data packet is sent to the NVMe device, and the NVMe device upgrade is triggered according to the upgrade command.

[0081] The pass-through command word can be only used to instruct the BMC not to parse the target upgrade data packet. At this time, an upgrade command needs to be added to the first pass-through command message. When the NVMe controller parses the upgrade command and the target upgrade data packet from the second pass-through command message, the NVMe controller responds to the upgrade command, sends the target upgrade data packet to the NVMe device, and triggers the upgrade of the NVMe device. The upgrade command can be a command based on the IPMI protocol. The upgrade command can be an existing command based on the IPMI protocol instead of a separately designed command.

[0082] In an embodiment of the present invention, only using the pass-through command word to instruct the BMC not to parse the target upgrade data packet can simplify the design of the pass-through command word and enrich the use of the pass-through command word. For example, not only using the pass-through command word to upgrade the NVMe device, but also combining the pass-through command word with other existing control commands to perform control operations on the NVMe device.

[0083] In one embodiment, the device upgrade method further includes:

[0084] After the host computer obtains the upgrade data packet, through the host computer, the upgrade data packet is segmented according to the size of the upgrade data packet and the payload of the first pass-through command to obtain a plurality of sub-upgrade data packets;

[0085] Through the host computer, the sub-upgrade data packet is used as the target upgrade data packet, and a first pass-through command message is generated according to the target upgrade data packet.

[0086] When the size of the upgrade data packet exceeds the payload of the first pass-through command, the upgrade data packet can be fragmented according to the size of the upgrade data packet and the payload of the first pass-through command, and the upgrade data packet is divided into multiple sub-upgrade data packets; then the sub-upgrade data packet is used as the target upgrade data packet, and a first pass-through command message is generated according to the target upgrade data packet. Then, according to the number of sub-upgrade data packets, the corresponding number of first pass-through command messages can be generated.

[0087] When upgrading the NVMe device, the host computer can pass each sub-upgrade data packet to the NVMe device through the BMC, which can decouple the coupling relationship between the BMC and the NVMe device and improve the upgrade flexibility.

[0088] In one embodiment, the device upgrade method further includes:

[0089] Receive and parse the second pass-through command message through the NVMe controller to obtain multiple sub-upgrade data packets;

[0090] Combine multiple sub-upgrade data packets through the NVMe controller to obtain an upgrade data packet, and perform a check on the upgrade data packet to obtain a check result;

[0091] Send a first response message including the check result to the BMC through the NVMe controller;

[0092] Receive the first response message sent by the BMC through the host computer, and send an upgrade start command to the BMC according to the check result;

[0093] Receive the upgrade start command sent by the BMC through the NVMe controller and trigger the NVMe device upgrade.

[0094] A second passthrough command packet contains a sub - upgrade data packet. By receiving and parsing the second passthrough command packet through the NVMe controller, each sub - upgrade data packet can be obtained. Through the NVMe controller, each sub - upgrade data packet can be combined to obtain an upgrade data packet. After obtaining the upgrade data packet, the NVMe controller can verify the upgrade data packet and generate a verification result. The verification content can include: the combination order of the sub - upgrade data packets, the integrity of the upgrade data packet, etc. The NVMe controller generates a first response packet according to the verification result, and the first response packet includes the verification result. The NVMe controller sends the first response packet to the host computer via the BMC. The host computer can determine whether the verification result in the first response packet meets a preset condition. The preset condition can be that the combination order of the sub - upgrade data packets is correct and the upgrade data packet is complete. If the verification result in the first response packet meets the preset condition, an upgrade start command can be sent. The upgrade start command is sent to the NVMe controller via the BMC. The NVMe controller receives and responds to the upgrade start command, triggering the upgrade of the NVMe device.

[0095] In one embodiment, the first passthrough command packet further includes: the total number of sub - upgrade data packets, the current number of sub - upgrade data packets, and the sub - upgrade data packet check code. By using the NVMe controller to combine multiple sub - upgrade data packets to obtain an upgrade data packet and verify the upgrade data packet, it includes:

[0096] Through the NVMe controller, according to the total number of sub - upgrade data packets and the current number of sub - upgrade data packets, multiple sub - upgrade data packets are combined to obtain an upgrade data packet, and the upgrade data packet is verified according to the sub - upgrade data packet check code.

[0097] When the size of the upgrade data packet exceeds the payload of the first passthrough command, the upgrade data packet can be fragmented according to the size of the upgrade data packet and the payload of the first passthrough command to obtain multiple sub - upgrade data packets. Then, the sub - upgrade data packets are used as target upgrade data packets, and a first passthrough command packet is generated according to the target upgrade data packets. When generating the first passthrough command packet, information such as the total number of sub - upgrade data packets, the current number of sub - upgrade data packets, and the sub - upgrade data packet check code can be added to the first passthrough command packet. Then, when the NVMe controller receives each second passthrough command packet and parses each sub - upgrade data packet from each second passthrough command packet, each sub - upgrade data packet can be combined according to the total number of sub - upgrade data packets and the current number of sub - upgrade data packets to obtain an upgrade data packet. At the same time, the upgrade data packet can be verified according to the sub - upgrade data packet check code.

[0098] In one embodiment, the device upgrade method further includes:

[0099] When the NVMe device completes the upgrade, it sends a second response message, which includes the upgrade result of the NVMe device.

[0100] When the NVMe device completes the upgrade, it can generate a second response message, which includes the upgrade result of the NVMe device. The second response message is sent to the host computer via the NVMe controller and the BMC. When the host computer receives the second response message, a round of device upgrade is completed.

[0101] In one embodiment, the program in the host computer can generate a first passthrough command message according to the device upgrade process and in combination with the passthrough command word, and send the first passthrough command message to the BMC based on the IPMI command. At the same time, the program can also parse the first response message and the second response message sent back via the BMC during the device upgrade process.

[0102] After the passthrough command word is designed, in addition to enabling the program in the host computer to generate a first passthrough command message in combination with the passthrough command word, it is also necessary to enable the BMC and the NVMe controller to parse and recognize the passthrough command word to ensure the smooth progress of the upgrade process.

[0103] Refer to Figure 2 , which shows the flowchart of a device upgrade method provided by an embodiment of the present invention. The host computer software sends the first passthrough command message to the BMC based on the IPMI command. The NVMe-MI (Non-Volatile Memory express Management Interface) upgrade module in the BMC receives the first passthrough command message and parses the first passthrough command message to obtain the driver type of the NVMe controller. The driver type of the NVMe controller can be I2C or PCIe. After determining the driver type of the NVMe controller, the driver adaptation layer in the BMC calls the corresponding driver module to encapsulate the first passthrough command message into the corresponding driver format to obtain a second passthrough command message. Then, the BMC sends the second passthrough command message to the corresponding NVMe controller according to the identifier of the NVMe controller parsed from the first passthrough command message, and finally triggers the NVMe device upgrade through the NVMe controller.

[0104] By constructing a pass-through command word and generating a pass-through command message according to the IPMI command, when the pass-through command message is transmitted to the BMC, after the BMC parses the pass-through command word, it does not perform any parsing on the subsequent content, and transmits the pass-through command message to the NVMe controller. After the NVMe controller parses the pass-through message, it obtains the command payload content and processes it. During the entire interaction process, the BMC is unaware of the message content and it is all a non-intrusive operation. This embodiment can reduce the coupling between the IPMI command and the BMC, and the host computer command control message can be developed independently, thereby reducing the frequency of BMC upgrades, improving the reliability of the server, and reducing the server maintenance cost.

[0105] It should be noted that for the method embodiments, for the sake of simple description, they are all expressed as a series of action combinations. However, those skilled in the art should know that the embodiments of the present invention are not limited by the described action sequence, because according to the embodiments of the present invention, certain steps can be performed in other sequences or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily essential for the embodiments of the present invention.
