The method includes: a host disabling a target operation command in response to an operation lock command issued by a user; receiving the operation command issued by the user and sending it to an SSD; while the SSD is executing the user-issued operation command, if the SSD receives an operation command from another user or process that is the target operation command, then the operation command from the other user or process is not executed; after the user-issued operation command is executed, the target operation command is enabled in response to an operation unlock command issued by the user. This invention first disables the target operation command, then executes the user-issued operation command, and finally enables the previously disabled target operation after the operation command is executed. This allows users to avoid other users or processes executing unwanted operations when using the SSD, thereby avoiding the problem of SSD malfunction caused by parallel operations.

[0052] Figure 4 This is a structural block diagram of an operation control device provided in an embodiment of the present invention. Detailed Implementation

[0053] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] To improve storage device availability, multiple users may share the same SSD; for the same user, multiple task processes may simultaneously access the same SSD. However, parallel operations in shared storage environments can easily lead to SSD anomalies such as difficulty maintaining data consistency, resource contention, and data loss due to accidental operations.

[0055] Currently, to address the aforementioned issues with shared storage, multiple namespaces (a unit of independent read and write operations for an SSD) can be used to divide the storage space into multiple subspaces and assign different subspaces to different users, ensuring independent read and write operations for each subspace. Alternatively, reservation technology can be employed, where multiple users sharing the same namespace can obtain read and write permissions by reserving a specific permission; users without reservations cannot read or write to the namespace. However, current methods primarily restrict user data read / write paths and command permissions, lacking restrictions on controller-level Admin commands. For example, two users might attempt to format or set features on the same SSD.

[0056] One of the core concepts of this invention is that it can disable a target operation command in response to a user-issued operation lock command; receive the user-issued operation command and send it to the SSD; while the SSD is executing the user-issued operation command, if the SSD receives an operation command from another user or other process that is the target operation command, then the operation command from the other user or other process will not be executed; after the user-issued operation command is executed, it enables the target operation command in response to a user-issued operation unlock command. This invention, by first disabling the target operation command, then executing the user-issued operation command, and finally enabling the previously disabled target operation after the user-issued operation command is executed, allows users to avoid other users or other processes executing unwanted operations when using the SSD, thereby avoiding the problem of SSD malfunctions caused by some parallel operations.

[0057] Reference Figure 1 The diagram illustrates a flowchart of an operation control method according to an embodiment of the present invention. The method is applied to a host computer, which is communicatively connected to a solid-state drive (SSD). The method may specifically include the following steps:

[0058] Step 101: In response to the operation lock command issued by the user, disable the target operation command.

[0059] In a specific implementation, the operation lock command can refer to the Lockdown command. The user can issue a Lockdown command, and the host can respond to the Lockdown command issued by the user to disable the target operation command, that is, the command sent to the controller or management endpoint of the NVM (Non-volatile memory) subsystem (which can refer to an SSD disk).

[0060] The types of disabled target operation commands can include Admin Command Set (SSD management command set), Feature Identifier of “set feature”, Management Interface Command Set (out-of-band management interface command set), and IO (Input / Output) Command Set (SSD read / write command set).

[0061] In this embodiment of the invention, a Lockdown operation command is used. The host can actively disable and re-enable some Admin management commands, IO read / write commands, and out-of-band management commands. Users can disable commands they do not want to be executed when using the SSD, thereby avoiding SSD disk anomalies caused by some parallel operations. Using the operation locking command can avoid some dangerous operations, such as SSD reset operations during formatting, and formatting operations during IO read / write operations.

[0062] Step 102: Receive the operation command issued by the user and send the operation command issued by the user to the SSD.

[0063] After disabling the target operation command, the user can issue operation commands, the host can receive the operation commands issued by the user, and then send the operation commands issued by the user to the SSD.

[0064] Step 103: When the SSD executes the operation command issued by the user, if the operation command issued by other users or other processes received by the SSD is the target operation command, then the operation command issued by other users or other processes will not be executed.

[0065] In practical implementation, when commands in the aforementioned command sets are defined as disabled by the Lockdown command, if the SSD receives disabled commands from other users or processes while executing user-issued operation commands, it can choose not to execute those other user or process commands. It should be noted that the Lockdown command itself belongs to the Admin Command Set, and it can be pre-configured so that the Lockdown command itself cannot be disabled.

[0066] Step 104: After the operation command issued by the user is executed, the target operation command is enabled in response to the operation enable command issued by the user.

[0067] In practical implementation, the operation opening command can refer to the Lockdown command. It should be noted that disabling and enabling a command can use different parameters of the same command. After the user-issued operation command is executed, the target operation command can be enabled in response to the user-issued Lockdown command.

[0068] In this embodiment of the invention, in response to a user-issued operation lock command, the target operation command can be disabled; the user-issued operation command can be received and sent to the SSD; while the SSD is executing the user-issued operation command, if the SSD receives an operation command from another user or other process that is the target operation command, then the operation command from the other user or other process will not be executed; after the user-issued operation command is executed, in response to a user-issued operation unlock command, the target operation command can be enabled. This embodiment of the invention, by first disabling the target operation command, then executing the user-issued operation command, and finally enabling the previously disabled target operation after the user-issued operation command is executed, allows users to avoid other users or other processes executing unwanted operations when using the SSD, thereby avoiding the problem of SSD malfunctions caused by some parallel operations.

[0069] Reference Figure 2 The diagram illustrates a flowchart of another operation control method provided by an embodiment of the present invention. The method is applied to a host computer, which is communicatively connected to a solid-state drive (SSD). The method may specifically include the following steps:

[0070] Step 201: Receive the user's command to view the disableable commands, and send the command to the SSD.

[0071] The command to view which commands can be disabled is the Supported Lockdown Log Page command. Users can use the Supported Lockdown Log Page command to see which commands in the current command set can be disabled.

[0072] In its implementation, the Supported Lockdown log page command, as a subcommand of the standard get log page command, can use the new log page id 14h. Specifically, in DW10 (Adobe Dreamweaver, a code editing software), bits 07:00 can be used to specify the log page id 14h, bits 11:08 can be used to specify the returned command set opcode, and other bytes can remain consistent with the standard get log page command.

[0073] Step 202: Receive the list of disabled commands that support operation locking commands returned by the SSD, so that the user can issue an operation locking command for the disabled commands according to the list of disabled commands.

[0074] In its implementation, when the Supported Lockdown log page command is successfully executed, it returns a list of commands that support Lockdown. See Table 1 for the data structure returned by the Supported Lockdown log page command.

[0075] Bytes name describe 0 Command type Indicates the type of command set returned. 1 Length This indicates the length of the returned data, i.e., there are n commands below. 3:2 Reserved fields / n+3:4 command and feature ID This indicates the command ID that supports Lockdown.

[0076] Table 1

[0077] As an example, the return result after executing the Supported Lockdown log page command can be as follows:

[0078] root@lihanqing-MS-7C82: / home / lhq / ms#. / inspurLli supported-lockdown-log / dev / nvme0

[0079] Supported Lockdown Log Page

[0080] request command type:0-Admin Command

[0081] command id(0):0x8

[0082] command id(1):0x9

[0083] command id(2):0xc

[0084] command id(3):0x10

[0085] command id(4):0x11

[0086] command id(5):0x14

[0087] command idi6):0x18

[0088] command id(7):0x1d

[0089] command id(8):0x1e

[0090] Step 203: In response to the operation lock command issued by the user, disable the target operation command.

[0091] In an optional embodiment, the operation locking command includes parameters of the command to be disabled. The parameters of the command to be disabled include the command set to which the command to be disabled belongs, the command identifier of the command to be disabled, and the permission settings corresponding to the command to be disabled. The permission settings include a disable setting. Step 203 may include the following sub-steps S11-S12:

[0092] Sub-step S11: Based on the command set to which the command to be disabled belongs, the command identifier of the command to be disabled, and the disabling settings corresponding to the command to be disabled, determine whether the command to be disabled is a command that the SSD supports disabling.

[0093] Sub-step S12: If the command to be disabled is a command that the SSD supports disabling, then disable the command to be disabled.

[0094] In its implementation, the Lockdown command, as a command in the Admin Command Set, can use the standard Admin command format. In this embodiment of the invention, when a command needs to be disabled, DW10 can be used to specify various parameters. Table 2 shows the parameters in the Lockdown command when a command needs to be disabled. Among them, Command opcode is used to represent the command identifier of the command to be disabled, Command type is used to represent the command set to which the command to be disabled belongs, and disable is used to represent the permission settings corresponding to the command to be disabled.

[0095]

[0096] Table 2

[0097] In this embodiment of the invention, the Command opcode, disable, and Command type parameters in the Lockdown command can be used to determine whether the command to be disabled is one that the SSD supports disabling. If the command to be disabled is one that the SSD supports disabling, then the command to be disabled can be disabled.

[0098] In an optional embodiment, the method may further include: if the command to be disabled is a command that the SSD does not support for disabling, then return an operation lock command error message.

[0099] In this embodiment of the invention, if the command to be disabled is one that the SSD does not support, then Lockdown is invalid and returns a command error. As an example, when the command opcode in DW10 specifies an unsupported opcode or id, the Lockdown command returns a "Prohibition of Command Execution Not Supported" error status. As another example, if the Command type field is set to 2h, and the NVM subsystem does not support MI functionality, the Lockdown command returns an "invalid field" error status.

[0100] It should be noted that the Lockdown command can be executed normally when it is used to disable a command that has been disabled or to re-enable a command that has been enabled.

[0101] Step 204: Receive the operation command issued by the user and send the operation command issued by the user to the SSD.

[0102] Step 205: When the SSD executes the operation command issued by the user, if the operation command issued by another user or another process received by the SSD is the target operation command, then the operation command issued by the other user or another process will not be executed.

[0103] In an optional embodiment, after the operation command issued by the other user or other process is not executed, the method may further include: receiving information returned by the SSD that the operation command issued by the other user or other process is in a disabled state.

[0104] In this embodiment of the invention, if the SSD receives an operation command from another user or other process issued by the host that is a disabled command, it will not execute the operation command, but will return information that the operation command is in a disabled state.

[0105] Step 206: After the operation command issued by the user is executed, in response to the operation enable command issued by the user, enable the target operation command.

[0106] In an optional embodiment, the operation lock command includes parameters of the command to be enabled. The parameters of the command to be enabled include the command set in which the command to be enabled is located, the command identifier of the command to be enabled, and the permission settings corresponding to the command to be enabled. The permission settings include an enable setting. Step 206 may include: after the operation command issued by the user is executed, enabling the command to be enabled according to the command set in which the command to be enabled is located, the command identifier of the command to be enabled, and the enable setting corresponding to the command to be enabled.

[0107] In this embodiment of the invention, after the operation command issued by the user is executed, the command that has been disabled can be re-enabled in response to the operation enable command issued by the user. At this time, DW10 can be used to specify each parameter. Table 3 shows the parameters in the Lockdown command when the command needs to be re-enabled.

[0108]

[0109] Table 3

[0110] In this embodiment of the invention, after the user-issued operation command is executed, the command to be enabled can be activated according to the Command opcode, disable, and Command type parameters in the Lockdown command.

[0111] In an optional embodiment, before disabling the target operation command in response to the operation lock command issued by the user, the method may further include: receiving a disabled command viewing command issued by the user and sending the disabled command viewing command to the SSD; receiving a list of disabled commands returned by the SSD so that the user can view the disabled commands according to the list of disabled commands.

[0112] The command to view disabled commands can be the Locked Log Page command. Users can use the Locked Log Page command to see which commands are currently disabled.

[0113] In its implementation, the Locked Log Page command can return a list of commands that have been locked, serving as a subcommand of the standard get log page command. It can use the new log page ID 15h. Specifically, you can specify the log page ID 14h using bits 07:00 in DW10, and specify the returned command set opcode using bits 11:08. Other bytes can remain consistent with the standard get log page command. It should be noted that the data structure returned by the Locked Log Page command can be the same as the data structure returned by the Supported Lockdown Log Page command.

[0114] In this embodiment of the invention, in response to a user-issued operation lock command, the target operation command can be disabled; the user-issued operation command can be received and sent to the SSD; while the SSD is executing the user-issued operation command, if the SSD receives an operation command from another user or other process that is the target operation command, then the operation command from the other user or other process will not be executed; after the user-issued operation command is executed, in response to a user-issued operation unlock command, the target operation command can be enabled. This embodiment of the invention, by first disabling the target operation command, then executing the user-issued operation command, and finally enabling the previously disabled target operation after the user-issued operation command is executed, allows users to avoid other users or other processes executing unwanted operations when using the SSD, thereby avoiding the problem of SSD malfunctions caused by some parallel operations.

[0115] To enable those skilled in the art to better understand the embodiments of the present invention, the description is specifically based on the format command. The format command can modify the attribute information of the controller and namespace, and the format command takes a certain amount of time to execute. Therefore, during the execution of the format command, it is necessary to prevent other commands that may modify the controller and namespace from being executed to avoid causing confusion. The Lockdown command can be used to achieve the above effect.

[0116] Reference Figure 3This document provides a flowchart illustrating the use of a Lockdown operation for locking, as provided in an embodiment of the present invention. Before executing the `format` command, related I / O (Input / Output) services can be stopped. The Lockdown command is used to disable I / O commands, namespace management-related creation, deletion, detach, attach commands, and other related commands. Then, the `format` command is executed. After `format` completes, the controller and namespace attribute information is identified through re-enumeration (identify) or re-initialization (reset). Finally, the Lockdown command is used to enable the previously disabled commands.

[0117] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions involved are not necessarily essential to the embodiments of the present invention.
