[0050] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0051] The prior art does not involve the consistency of RAID card and disk firmware versions, and lacks a scheme for automatic upgrade of disks or RAID cards by a host. In this case, the user needs to refer to the disk version support information provided by the RAID card manufacturer, go to the official website of the disk manufacturer to download the corresponding firmware version, and finally manually upgrade the disk, which seriously reduces the user experience and operation and maintenance efficiency.

[0052] Therefore, the embodiments of the present application propose a disk array firmware version upgrade scheme, which can realize automatic upgrade of a disk array card and consistency upgrade of the firmware of the disks accessed by the disk array card.

[0053] The embodiments of the present application disclose a disk array firmware version upgrade method, which comprises the steps of Figure 1 as shown in the figure, comprising:

[0054] Step S11: Obtain a disk array card upgrade request issued by a host, and return a message notification allowing the disk array card to be upgraded to the host when the disk array card meets a preset upgrade condition.

[0055] Figure 2 A disk array consistency upgrade framework proposed by the present application is shown in the figure,Figure 2 As shown, the hardware part of the present application is composed of target Flash in the RAID card and the firmware backup disk connected to the RAID card, wherein the Flash stores the firmware image of each module of the RAID card and the list of disk firmware versions supported by the RAID card, collectively referred to as the RAID card firmware package (i.e. upgrade data), and the firmware backup disk is used to store the upgraded disk firmware, which is directly obtained from the disk to perform fast and consistent upgrade when the RAID card is inserted into the same disk. The software part is composed of the upgrade host computer on the host side and the upgrade management thread in the RAID management module in the RAID card, wherein the upgrade host computer on the host side is responsible for downloading the RAID card firmware package or disk firmware from the firmware download server (i.e. target server) through HTTPS (Hypertext Transfer Protocol Secure), and then transmitting the upgrade data or firmware to the RAID card through PCIe (peripheral component interconnect express). The upgrade management thread in the RAID card receives the data issued by the host and calls the Flash management module through the RPC (Remote Procedure Call) to write the Flash interface for firmware storage. The thread also implements the consistency check and upgrade of the disk firmware and the RAID card firmware package version. Through the cooperation between the above-mentioned software and hardware, the package upgrade of the disk array and the consistency upgrade of the disk firmware and the package version are realized.

[0056] Figure 3 The data arrangement of the RAID card firmware package in the Flash disclosed in the present application is shown in FIG. 1. Figure 3 As shown, the head of the package is the firmware version list used to describe the package version number and the firmware version number of each module of the RAID card. After the upgrade is completed, these version numbers and the version numbers read from each module are compared to confirm whether the upgrade is successful. Further stored are the firmware images of each module of the RAID card. Each time the RAID card is reset, each module loads the firmware image from the Flash into the memory of each module and then starts. Finally stored is the list of all disk firmware versions supported by the package, which is stored according to different manufacturers and models. These version numbers are used to compare with the current firmware version number of the disk at startup or when a new disk is inserted, to confirm whether the disk and the RAID card firmware package version are consistent.

[0057] The disk array firmware version upgrade method of the present application is described in detail below based on the above framework:

[0058] Figure 4This is a flowchart illustrating the firmware upgrade process for a RAID card on the disk array card side according to this application. (See attached diagram) Figure 4 As shown, in this embodiment, the host receives the disk array card upgrade request sent when upgrade data with a version level higher than the target version level exists on the target server. Here, the target version level is the current version level of the disk array card, and the target server is the upgrade data download server. Further, when the disk array card is idle, it is determined that the disk array card meets preset upgrade conditions, and a message notification allowing the upgrade of the disk array card is returned to the host. It should be noted that this embodiment can also send messages to the host via the disk array card at preset time intervals to inquire whether the host has obtained upgrade data with a version level higher than the current version level of the disk array card, in order to achieve a more comprehensive and efficient RAID card firmware package upgrade process.

[0059] Specifically, the host sends an upgrade request to the RAID card. Upon receiving the upgrade request, the RAID management module wakes up the upgrade management thread, which then initiates the RAID card firmware upgrade process. Further, it checks whether the current RAID card status supports the upgrade. If the RAID card is currently writing user data sent by the host to the disk, or is busy processing other events, and its status does not support the upgrade, the upgrade management thread will send a message to the host rejecting the upgrade request. Conversely, if the RAID card's current status supports the upgrade, it will send a message to the host allowing the upgrade.

[0060] Step S12: Receive upgrade data sent by the host, control the disk array card to load the firmware image in the upgrade data and control the disk array card to restart; wherein, the upgrade data includes the firmware image and a list of disk firmware versions supported by the disk array card.

[0061] In this embodiment, the system receives upgrade data from the host and writes the upgrade data to the target flash memory. Furthermore, it controls the disk array card and calls the reset interface to read the upgrade data from the target flash memory, loads the firmware image in the upgrade data, and controls the disk array card to restart.

[0062] Specifically, the RAID card receives the upgrade data, the upgrade data is transmitted in a size of 4K, after receiving a data packet, the upgrade management thread calls the write Flash interface of the Flash management module through RPC to write the upgrade data packet into the Flash, when the upgrade data packet is downloaded and saved into the Flash, the upgrade management thread calls the reset interface of the RAID card to perform upgrade reset, all modules in the RAID card will load the firmware image from the Flash again and start from the new image. After restarting, the RAID card and the host re-establish the PCIe link, the upgrade management thread checks whether the version of each module of the RAID card is the same as the version in the firmware version list, if the same, the upgrade is successful, if not, the upgrade fails, finally, the upgrade management thread sends the result of the large packet upgrade to the host upgrade host computer through PCIe. In the embodiment, the upgrade of the firmware of each module of the RAID card is completed through the above process, and the disk model supported by the version large packet and the corresponding version are also saved in the Flash, which prepares for the subsequent disk firmware version consistency upgrade.

[0063] Step S13: The firmware versions of the disks accessed by the disk array card are traversed, and when the firmware version of any disk does not exist in the disk firmware version list, the corresponding target disk firmware is found from the firmware backup disk according to the model of the any disk; the firmware backup disk stores the upgraded disk firmware.

[0064] Figure 5 A disk consistency upgrade flowchart of the disk array card side of the present application is shown in FIG. 1, in the embodiment, the firmware versions of the disks accessed by the disk array card are traversed, when the firmware version of any disk does not exist in the disk firmware version list, it is indicated that the disk needs to be upgraded, at this time, the corresponding target disk firmware is found from the firmware backup disk according to the model of the any disk. Figure 5

[0065] Specifically, the upgrade management thread calls the Flash management module through RPC to read the disk firmware version list supported by the RAID card and store it in the memory of the RAID card management module. On the one hand, if the RAID card is restarted, the firmware version of each disk accessed by the RAID card is traversed through PCIe / SATA (Serial ATA, a computer bus interface), and it is checked whether the version is in the disk firmware version list supported by the RAID card. On the other hand, if a new disk is inserted at runtime, only the version of the newly inserted disk is checked whether it is in the supported disk firmware version list, if not, the corresponding target disk firmware is found from the firmware backup disk according to the model of the corresponding disk.

[0066] ​Step S14: If the firmware version of the target disk firmware exists in the disk firmware version list, upgrade the any disk by the target disk firmware, so as to realize the consistent upgrade of the disk accessed by the disk array card after the upgrade of the disk array card.

[0067] In this embodiment, if the firmware version of the target disk firmware exists in the disk firmware version list, upgrade the any disk by the target disk firmware, so as to realize the consistent upgrade of the disk accessed by the disk array card after the upgrade of the disk array card. After the upgrade, it is judged whether the current firmware version of the any disk exists in the disk firmware version list. If the current firmware version of the any disk exists in the disk firmware version list, it indicates that the upgrade is successful, and the any disk is marked as available state, and then the next disk accessed by the disk array card is traversed. If the current firmware version of the any disk does not exist in the disk firmware version list, it indicates that the upgrade fails, and the any disk is marked as unavailable state, and then the disk information of the any disk is reported to the host.

[0068] It should be noted that when the corresponding target disk firmware is searched from the firmware backup disk according to the model of the corresponding disk, if the corresponding target disk firmware cannot be searched from the firmware backup disk, a download request of the corresponding disk firmware is initiated to the host, and the any disk is upgraded according to the disk firmware issued by the host, and then the disk firmware issued by the host is saved to the firmware backup disk.

[0069] In this embodiment, after the host receives the download request of the disk firmware, it checks the network link of the target server. If the network link is an unavailable link, a message notification of download failure is returned to the disk array card, and a message prompt of download failure and a corresponding first download failure reason are displayed to the user by the host. If the network link is an available link, the corresponding disk firmware is queried from the target server. If the corresponding disk firmware does not exist in the target server, a message notification of download failure is returned to the disk array card, and a message prompt of download failure and a corresponding second download failure reason are displayed to the user by the host. If the corresponding disk firmware exists in the target server, the corresponding disk firmware is downloaded to the local, and the corresponding disk firmware is issued to the disk array card based on the standard of high-speed serial computer expansion bus and the interface specification of non-volatile memory host controller, so that the disk array card upgrades the any disk according to the corresponding disk firmware issued by the host.

[0070] Specifically, if the current traversed disk firmware version is in the list of disk firmware versions supported by the RAID card, it indicates that the firmware version of the disk is consistent with the large package version, and no consistency upgrade is needed, and the next disk is continued to be traversed. If the current traversed disk firmware version is not in the list of disk firmware versions supported by the RAID card, it indicates that the firmware version of the disk is inconsistent with the large package version, and consistency upgrade is needed, and the consistency upgrade process is started. The consistency upgrade process specifically includes: the upgrade management thread searches for the disk model with inconsistent version in the disk firmware backup disk, and confirms whether the disk firmware version of the model in the backup disk is in the list of disk firmware versions supported by the RAID card. If the disk firmware backup disk exists the firmware, the upgrade management thread directly reads the firmware from the backup disk through PCIe or SATA, and upgrades the firmware of the disk, and then checks whether the firmware version of the disk is consistent with the large package. If it is consistent, mark the disk state as available, and continue to traverse the next disk. If it is still inconsistent, it indicates that the disk firmware upgrade is not successful, the disk is marked as unavailable, and the information of the disk is reported to the host. If the disk firmware backup disk does not exist the firmware, the upgrade management thread sends the model of the disk and the firmware version that needs to be upgraded to the host upgrade host computer, and requests the host upgrade host computer to download the firmware. If the host successfully obtains the firmware, the firmware is downloaded to the RAID card through PCIe, the upgrade management thread receives the firmware, and then upgrades the disk. After the upgrade is completed, the disk model and the firmware are stored in the disk firmware backup disk, so that the next time the same disk is inserted, consistency upgrade is performed. Further, it is checked whether the firmware version of the upgraded disk is consistent with the large package. If it is consistent, the disk is marked as available, and the next disk is continued to be traversed. If the version is still inconsistent, it indicates that the disk firmware upgrade is not successful, the disk is marked as unavailable, and the information of the disk is reported to the host. If the firmware is failed to be obtained from the host, usually the corresponding version cannot be found on the remote firmware server of the host. The upgrade management thread marks the state of the disk as unavailable, and reports the disk information to the host. When the RAID card is restarted, the consistency check of all disk firmware versions is completed or the consistency traversal of the firmware version of the newly inserted disk is completed when the upgrade management thread ends the consistency upgrade process. In the embodiment, the upgrade management thread not only completes the consistency check and upgrade of each disk in the consistency upgrade process, but also generates the available state of all currently connected disks. Other business functions of the RAID card management module skip the disk whose version is inconsistent with the current large package version and whose consistency upgrade fails. At the same time, these unavailable disks are also reported to the host, prompting the user to use other ways to upgrade or replace the disk.

[0071] Figure 6For a host side RAID card firmware large package upgrade flowchart of the application, the user operates the host computer to start the RAID card large package upgrade process, first queries the model and the current firmware large package version of the RAID card, then queries whether the latest version of the RAID card of the model exists in the firmware server, if the current version and the server version are the same, prompts the user that the current RAID card is the latest version and does not need to be upgraded. If a new version of the RAID card large package than the current RAID card is found, the package is downloaded to the host, then the PCIe interface is used to initiate an upgrade request to the RAID card through the NVME protocol, if the RAID card is busy processing other transactions at this time, it may refuse the upgrade request, the host computer receives the rejection request and reminds the user to retry later. If the RAID card accepts the upgrade request, the host computer transmits the downloaded RAID card large package to the RAID card, the transmission process divides the large package into several 4K data packets for transmission, and sends a start large package upgrade command to the RAID card after the transmission is completed. Then the host computer waits for the upgrade result of the RAID card and prompts the user with the upgrade result. Through the above process, the large package upgrade of the RAID card firmware is realized, and the disk firmware version supported by the RAID card large package is also downloaded to the RAID card, preparing for subsequent disk firmware version consistency upgrade.

[0072] Figure 7 For a host side disk consistency upgrade flowchart of the application, the host computer receives a disk firmware consistency upgrade request from the RAID card, which contains the disk type and disk firmware version number to be upgraded. The host computer first tries to link the disk manufacturer firmware download server according to the model of the disk, if the link fails, it replies to the RAID card that the disk firmware acquisition fails, and prompts the user the reason for the failure of the consistency upgrade. If the link is normal, the disk firmware download server is queried according to the required disk version number to obtain the disk firmware and download it, if the required disk version cannot be found, the RAID card is replied that the disk firmware acquisition fails, and the user is prompted the reason for the failure of the disk consistency upgrade. If the host computer queries the required disk firmware, it downloads the firmware to the host, then transmits the firmware to the RAID card through PCIe using the NVME protocol. After the disk firmware transmission is completed, the host computer notifies the RAID card to upgrade the disk firmware, then waits for the RAID card to return the upgrade result. The host computer prompts the user the disk firmware consistency upgrade result.

[0073] In the disk firmware consistency upgrade process, the host-side upgrade host computer realizes the search and download of the disk firmware, and transmits the firmware version to the RAID card, and prompts the user for the execution result of each link. The upgrade host computer software supports the RAID card to report multiple disk consistency upgrade requests at the same time, and performs consistency upgrade on these disks one by one according to the above process. Since the consistency upgrade will upgrade the user's disk firmware version, when the user installs the upgrade host computer software on the host side, the user will be prompted to confirm whether to automatically upgrade the disk firmware for consistency. If the user does not agree to this permission, when the RAID card sends a disk firmware consistency upgrade request, the host computer will ask the user to choose whether to perform consistency upgrade, and the user agrees to initiate the disk firmware consistency upgrade operation.

[0074] The present application proposes a method of automatically identifying the disk and RAID card firmware version consistency of a disk array and automatically upgrading the disk firmware. Each time the RAID card upgrades the firmware version, the disk types supported by the RAID card firmware version and the corresponding version will be downloaded to the RAID card along with the RAID card firmware upgrade package, and saved to the Flash inside the RAID card. When starting or inserting a new disk, the disk management module of the RAID card will traverse all the accessed disk firmware versions to check whether they are consistent with the disk version supported by the RAID card. If they are not consistent, the RAID card disk management module will request the host's upgrade agent to link to the Internet to download the disk firmware version supported by the RAID card, and automatically upgrade the disk with inconsistent version to the version consistent with the RAID card supported disk list, thereby realizing automatic disk firmware version consistency management. In addition, the present application also introduces a disk firmware backup mechanism, which automatically backs up the disk firmware to a device specially storing disk firmware after each upgrade. This mechanism can play a role when the same disk is inserted again next time. If the firmware version is detected to be inconsistent, the RAID card disk management module will directly read the firmware from the backup disk and upgrade the inserted disk, without going through the process of host request and server download, thereby improving the speed of disk firmware consistency upgrade.

[0075] It can be seen that the application provides a disk array firmware version upgrading method applied to a disk array card, including: obtaining a disk array card upgrading request issued by a host, and returning a message notification allowing the disk array card to be upgraded to the host when the disk array card meets a preset upgrading condition; receiving upgrading data issued by the host, and controlling the disk array card to load a firmware image in the upgrading data and controlling the disk array card to restart; wherein the upgrading data contains the firmware image and a disk firmware version list supported by the disk array card; traversing firmware versions of disks accessed by the disk array card, and when a firmware version of any disk does not exist in the disk firmware version list, searching for a corresponding target disk firmware from a firmware backup disk according to a model of the any disk; the firmware backup disk stores upgraded disk firmware; if a firmware version of the target disk firmware exists in the disk firmware version list, upgrading the any disk through the target disk firmware, so that after the disk array card is upgraded, consistent upgrading of the disks accessed by the disk array card is realized. It can be seen from the above that the firmware image and the disk firmware version list supported by the disk array card in the application are downloaded into the disk array card as upgrading data, realizing quick and direct checking of consistency of accessed disk firmware versions. Further, the application realizes full automation of disk array firmware consistency checking and consistent upgrading through mutual cooperation of upgrading management threads of the host and the disk array card. In addition, the application backs up the upgraded disk firmware to a disk firmware backup disk, so that the firmware can be directly obtained from the disk firmware backup disk when a disk of the same model is inserted, the process of searching and downloading from a remote server is saved, and the speed of disk firmware consistent upgrading is improved.

[0076] Correspondingly, the application also discloses a disk array firmware version upgrading device, referring to Figure 8 The device includes:

[0077] The request obtaining module 11 is configured to obtain a disk array card upgrading request issued by a host, and return a message notification allowing the disk array card to be upgraded to the host when the disk array card meets a preset upgrading condition.

[0078] The disk array card upgrading module 12 is configured to receive upgrading data issued by the host, control the disk array card to load a firmware image in the upgrading data, and control the disk array card to restart; wherein the upgrading data contains the firmware image and a disk firmware version list supported by the disk array card.

[0079] The disk firmware acquisition module 13 is configured to traverse firmware versions of disks accessed by the disk array card, and when a firmware version of any disk does not exist in the disk firmware version list, find corresponding target disk firmware from the firmware backup disk according to a model of the any disk; the firmware backup disk stores upgraded disk firmware.
