[0034] In order to enable those skilled in the art of this technology to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0035] Next, the application environment of the SATA storage device information transmission method provided by the embodiments of the present application will be briefly described.

[0036] Such as Figure 1As shown in the figure, the application environment is a SATA storage system, which includes a storage controller 100, a first SATA switch (SATA Switch) 200, a second SATA switch 300, each first SATA storage device 400, and each second SATA storage device 500. Among them, the storage controller 100 is connected to the first SATA switch 200 and the second SATA switch 300. The first SATA switch 200 is connected to each first SATA storage device 400, and the second SATA switch 300 is connected to each second SATA storage device 500. The first SATA switch 200 is cascaded with the second SATA switch 300. The storage controller 100 is used to connect to the host device 600.

[0037] In a first aspect, as Figure 2 shown, a method for transmitting SATA storage device information is provided. Taking the first SATA switch 200 in Figure 1 as an example, the method includes the following steps 201 to 203.

[0038] Step 201: In response to receiving an information transmission request message sent by the storage controller, determine the frame information structure type according to the information transmission request message.

[0039] Specifically, the storage controller 100 receives an information transmission request sent by the host device 600, performs format conversion processing on the information transmission request to obtain an information transmission request message, and sends the information transmission request message to the first SATA switch 200. Then, the first SATA switch 200 receives the information transmission request message sent by the storage controller and determines the frame information structure (Frame Information Structure, FIS) type according to the information transmission request message.

[0040] In one embodiment, as Figure 3 shown, the frame information structure type includes a device-to-device type, a host-to-device type, or a device-to-host type. Determining the frame information structure type according to the information transmission request message includes steps 301 to 302.

[0041] Step 301: Analyze the information transmission request message to obtain the request type.

[0042] Step 302: In response to the request type being a SATA storage device-to-device request, parse the information transmission request message to obtain the frame information structure type, and modify the frame information structure type to the device-to-device type.

[0043] Among them, the request types include requests between SATA storage devices. The requests between SATA storage devices are used to represent requests for information transmission between SATA storage devices. It can be understood that a custom frame information structure type, namely the device-to-device type, is pre-configured in the first SATA switch 200.

[0044] Specifically, the first SATA switch 200 analyzes the information transmission request message to obtain the request type; then, in response to the request type being a request between SATA storage devices, it parses the information transmission request message to obtain the frame information structure type, and modifies the frame information structure type to the device-to-device type, improving the convenience and efficiency of determining the frame information structure type.

[0045] In one embodiment, as Figure 3 shown, determining the frame information structure type according to the information transmission request message includes step 303.

[0046] Step 303, in response to the request type not being a request between SATA storage devices, parse the information transmission request message to obtain the frame information structure type.

[0047] Specifically, the first SATA switch 200, in response to the request type not being a request between SATA storage devices, parses the information transmission request message to obtain the frame information structure type, improving the convenience and efficiency of determining the frame information structure type.

[0048] In this embodiment, in response to the request type not being a request between SATA storage devices, parsing the information transmission request message to obtain the frame information structure type improves the convenience and efficiency of determining the frame information structure type.

[0049] Step 202, in response to the frame information structure type being the device-to-device type, determine the source device and the destination device according to the information transmission request message, and forward the information transmission request message to the source device.

[0050] Among them, the source device is the first SATA storage device 400 that sends the first storage device information; the destination device is the first SATA storage device 400 or the second SATA storage device 500 that receives the first storage device information; the first SATA storage device 400 is connected to the first SATA switch 200; the second SATA storage device 500 is connected to the second SATA switch 300.

[0051] Specifically, when the first SATA switch 200 identifies that the frame information structure type is the device-to-device type, it determines the source device and the target device according to the information transmission request message, and forwards the information transmission request message to the source device, so that the source device obtains the first storage device information according to the information transmission request message and sends the first storage device information to the first SATA switch 200.

[0052] In one embodiment, as Figure 4 shown, determining the source device and the target device according to the information transmission request message includes steps 401 to 403.

[0053] Step 401, parse the information transmission request message to obtain the first device virtual address of the source device and the second device virtual address of the target device;

[0054] Step 402, determine the source device according to the first device virtual address;

[0055] Step 403, determine the target device according to the second device virtual address.

[0056] Specifically, the first SATA switch 200 parses the information transmission request message to obtain the first device virtual address of the source device and the second device virtual address of the target device; then, determines the source device according to the first device virtual address; and then, determines the target device according to the second device virtual address, improving the efficiency and convenience of determining the source device and the target device. In addition, the first device virtual address and the second device virtual address can be but are not limited to broadcast common addresses.

[0057] In this embodiment, the information transmission request message is parsed to obtain the first device virtual address of the source device and the second device virtual address of the target device; then, the source device is determined according to the first device virtual address; and then, the target device is determined according to the second device virtual address, improving the efficiency and convenience of determining the source device and the target device.

[0058] Step 203, in response to receiving the first storage device information sent by the source device, output the first storage device information to the target device.

[0059] Specifically, when the first SATA switch 200 receives the first storage device information sent by the source device, it outputs the first storage device information to the target device, thereby realizing that the first storage device information sent by the source device is output to the target device through the first SATA switch 200 without passing through the storage controller 100 or memory processing, realizing direct communication between the source device and the target device, and thus realizing the P2P function of SATA to SATA, improving the data transmission efficiency, saving the host resource occupation, and being applicable to data storage scenarios with low latency and high concurrency.

[0060] In one embodiment, forwarding the information transmission request message to the source device includes broadcasting the information transmission request message according to the first device virtual address, so that the information transmission request message is forwarded to the source device; wherein, outputting the first storage device information to the target device includes:

[0061] Determining the switch connected to the target device according to the target device;

[0062] In response to the switch connected to the target device being the first SATA switch, broadcasting the first storage device information according to the second device virtual address, so that the first storage device information is output to the target device.

[0063] Specifically, the first SATA switch 200 broadcasts the information transmission request message according to the first device virtual address, so that the information transmission request message is forwarded to the source device; then, when the switch connected to the target device is the first SATA switch 200, that is, when the switch connected to the target device is the same as the switch connected to the source device at this time, the first SATA switch 200 can directly broadcast the first storage device information according to the second device virtual address, so that the first storage device information is output to the target device, improving the efficiency and convenience of the first storage device information transmission, realizing that the first storage device information sent by the source device is output to the target device through the first SATA switch 200 without passing through the storage controller 100 or memory processing, realizing direct communication between the source device and the target device, and thus realizing the P2P function of SATA to SATA, improving the data transmission efficiency, saving the host resource occupancy, and being applicable to low-latency and high-concurrency data storage scenarios.

[0064] In this embodiment, the information transmission request message is broadcast according to the first device virtual address, so that the information transmission request message is forwarded to the source device; then, when the switch connected to the target device is the first SATA switch 200, that is, when the switch connected to the target device is the same as the switch connected to the source device at this time, the first SATA switch 200 can directly broadcast the first storage device information according to the second device virtual address, so that the first storage device information is output to the target device, improving the efficiency and convenience of the first storage device information transmission, realizing that the first storage device information sent by the source device is output to the target device through the first SATA switch 200 without passing through the storage controller 100 or memory processing, realizing direct communication between the source device and the target device, and thus realizing the P2P function of SATA to SATA, improving the data transmission efficiency, saving the host resource occupancy, and being applicable to low-latency and high-concurrency data storage scenarios.

[0065] In one embodiment, outputting the first storage device information to the target device further includes:

[0066] In response to the switch connected to the target device being the second SATA switch, forwarding the first storage device information to the second SATA switch, and sending an information broadcast instruction to the second SATA switch.

[0067] The information broadcast instruction is used to instruct the second SATA switch 300 to broadcast the first storage device information to the target device according to the second device virtual address; the first SATA switch 200 is cascaded with the second SATA switch 300.

[0068] Specifically, when the switch connected to the target device is the second SATA switch 300, that is, when the switch connected to the target device is different from the switch connected to the source device at this time, the first SATA switch 200 needs to first forward the first storage device information to the second SATA switch 300, and then send an information broadcast instruction to the second SATA switch 300, so that the second SATA switch 300 broadcasts the first storage device information to the target device according to the second device virtual address, realizing direct communication between SATA storage devices under different SATA switches, improving the efficiency and convenience of the first storage device information transmission, realizing that the first storage device information sent by the source device is output to the target device through the first SATA switch 200 without passing through the storage controller 100 or memory processing, realizing direct communication between the source device and the target device, and thus realizing the P2P function of SATA to SATA, improving the data transmission efficiency, saving the host resource occupancy, and being applicable to data storage scenarios with low latency and high concurrency.

[0069] In this embodiment, in response to the switch connected to the target device being the second SATA switch 300, forwarding the first storage device information to the second SATA switch 300, and sending an information broadcast instruction to the second SATA switch 300, so that the second SATA switch 300 broadcasts the first storage device information to the target device according to the second device virtual address, realizing direct communication between SATA storage devices under different SATA switches, improving the efficiency and convenience of the first storage device information transmission, realizing that the first storage device information sent by the source device is output to the target device through the first SATA switch 200 without passing through the storage controller 100 or memory processing, realizing direct communication between the source device and the target device, and thus realizing the P2P function of SATA to SATA, improving the data transmission efficiency, saving the host resource occupancy, and being applicable to data storage scenarios with low latency and high concurrency.

[0070] Based on this, for the above SATA storage device information transmission method, in response to receiving an information transmission request message sent by the storage controller, the frame information structure type is determined according to the information transmission request message; then, in response to the frame information structure type being the device-to-device type, the source device and the target device are determined according to the information transmission request message, and the information transmission request message is forwarded to the source device; the source device is the first SATA storage device 400 that sends the first storage device information; the target device is the first SATA storage device 400 or the second SATA storage device 500 that receives the first storage device information; the first SATA storage device 400 is connected to the first SATA switch 200; the second SATA storage device 500 is connected to the second SATA switch 300; then, in response to receiving the first storage device information sent by the source device, the first storage device information is output to the target device, thereby realizing that the first storage device information sent by the source device is output to the target device through the first SATA switch 200 without passing through the storage controller 100 or memory processing, realizing direct communication between the source device and the target device, and thus realizing the P2P function of SATA to SATA, improving the data transmission efficiency, saving the host resource occupancy, and being applicable to data storage scenarios with low latency and high concurrency.

[0071] In one embodiment, as Figure 5 shown, the method further includes step 501 and step 502.

[0072] Step 501, in response to the frame information structure type being the host-to-device type, determine the information receiving device according to the information transmission request message, and obtain the host device information to be transmitted after parsing the information transmission request message;

[0073] Step 502, forward the host device information to be transmitted to the information receiving device.

[0074] Among them, the information receiving device is the first SATA storage device 400 that receives the host device information to be transmitted. Specifically, in response to the frame information structure type being the host-to-device type, the first SATA switch 200 determines the information receiving device according to the information transmission request message, and obtains the host device information to be transmitted after parsing the information transmission request message; then, forwards the host device information to be transmitted to the information receiving device, thereby realizing the information transmission between the host device 600 and the SATA storage device, and improving the efficiency and convenience of the SATA storage device information transmission.

[0075] In this embodiment, in response to the frame information structure type being the host-to-device type, the information receiving device is determined according to the information transmission request message, and the information of the host device to be transmitted is obtained after parsing the information transmission request message; then, the information of the host device to be transmitted is forwarded to the information receiving device, thereby realizing the information transmission between the host device 600 and the SATA storage device, and improving the efficiency and convenience of the information transmission of the SATA storage device.

[0076] In one embodiment, as Figure 5 shown, the method further includes step 503 and step 504.

[0077] Step 503, in response to the frame information structure type being the device-to-host type, determine the information sending device according to the information transmission request message, and forward the information transmission request message to the information sending device;

[0078] Step 504, in response to receiving the second storage device information sent by the information sending device, send an information transmission instruction and the second storage device information to the storage controller.

[0079] Among them, the information sending device is the first SATA storage device 400 that sends the second storage device information; the information transmission instruction is used to instruct the storage controller to transmit the second storage device to the host device. Specifically, the first SATA switch 200, in response to the frame information structure type being the device-to-host type, determines the information sending device according to the information transmission request message, and forwards the information transmission request message to the information sending device; then, in response to receiving the second storage device information sent by the information sending device, sends an information transmission instruction and the second storage device information to the storage controller, thereby realizing the information transmission between the SATA storage device and the host device 600, and improving the efficiency and convenience of the information transmission of the SATA storage device.

[0080] In this embodiment, in response to the frame information structure type being the device-to-host type, determine the information sending device according to the information transmission request message, and forward the information transmission request message to the information sending device; then, in response to receiving the second storage device information sent by the information sending device, send an information transmission instruction and the second storage device information to the storage controller, thereby realizing the information transmission between the SATA storage device and the host device 600, and improving the efficiency and convenience of the information transmission of the SATA storage device.

[0081] In a specific example, outputting the first storage device information to the target device includes:

[0082] Performing data encryption processing on the first storage device information to obtain the encrypted first storage device information;

[0083] Perform data compression processing on the encrypted first storage device information to obtain the compressed first storage device information;

[0084] Perform data verification processing on the compressed first storage device information to obtain the verified first storage device information;

[0086] Output the encapsulated first storage device information to the target device, which improves the efficiency, accuracy, and convenience of the transmission of SATA storage device information. The above is only a specific example, and in actual applications, it can be flexibly set according to user needs and is not limited here.

[0087] Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by means of software plus a necessary general hardware platform.
