Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a concurrent access method, system, terminal and storage medium for BMC remote services. Background Art

[0002] The SOL function of BMC is an important means of remote monitoring and management of servers. By redirecting the server BIOS / OS serial port I / O to the BMC serial port I / O based on the network, the operation and maintenance personnel can remotely access the server locally to view data, set parameters, and perform other operations. For the serial port on the OS side of the server, under the premise that the hardware UART Route is correctly adapted, after the SOL function is enabled through the IPMI command, the user can see the data stream output by the serial port under the open SOL client. SOL has multiple (usually 4) clients, but currently only supports opening a client with a UART Route adapted to the OS serial port. For example, when A opens the SOL client with activate instance=1 locally, B enters the command activateinstance=2 locally, but cannot open the client, and will be prompted that the SOL client has been opened. In other words, the current SOL clients cannot meet the needs of multiple people to remotely access and manage server resources at the same time. Summary of the invention

[0035] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0036] Figure 1 is a schematic flow chart of a method according to an embodiment of the present invention. Figure 1 The execution subject may be a concurrent access system of a BMC remote service.

[0037] like Figure 1 As shown, the method includes:

[0038] Step 110, receiving operating system data from a BMC serial port, wherein the BMC serial port is communicatively connected to the operating system serial port;

[0039] Step 120: parsing the target address of the operating system data, and sending the operating system data to the corresponding remote service access process according to the target address.

[0040] This method realizes the function of multiple people remotely accessing server OS resources at the same time through hardware UART Route configuration and firmware code optimization, meets the needs of remote collaborative management, and greatly improves work efficiency; provides a hierarchical authority management method to ensure the stability and security of server resources while meeting the needs; provides ipmi commands for turning on / off SOL Multi Clients to meet the needs of different customer usage scenarios.

[0041] To facilitate understanding of the present invention, the concurrent access method for BMC remote services provided by the present invention is further described below based on the principle of the concurrent access method for BMC remote services of the present invention and in combination with the process of concurrently accessing BMC remote services in the embodiment.

[0042] Specifically, the concurrent access method of the BMC remote service includes:

[0043] S1. Receive operating system data from a BMC serial port, where the BMC serial port is communicatively connected with the operating system serial port.

[0044] Build a communication link between the BMC serial port and the operating system serial port from the software layer. Specifically, connect UART1 (OS serial port) on the BMC AST2600 chip to UART4 (BMC serial port), and connect PORT1 to PORT4. This step can realize the output of OS serial port data to the BMC serial port. For example, connect UART1 (OS serial port) and UART4 (BMC serial port) on the BMC AST2600 chip bidirectionally. When UART1 is used as the data stream transmitter and UART4 is used as the data stream receiver, the SOL client can read OS serial port data; when UART4 is used as the data stream transmitter and UART1 is used as the data stream receiver, the SOL client can write to the OS.

[0045] S2. Parse the target address of the operating system data, and send the operating system data to a corresponding remote service access process according to the target address.

[0046] The data received by UART4 is forwarded to all remote service access processes (SOL clients), so that multiple clients can output OS serial port data at the same time, realizing the read function of SOL Multi Clients.

[0047] Furthermore, in this embodiment, the read requirements of different users are met by carrying the address in the data. On this basis, targeted queries on OS serial port data can be implemented, for example, the user sends a read request through a process, the read request carries the process address, and the operating system returns the corresponding data carrying the address according to the received read request.

[0048] In the present invention, multiple SOL clients are implemented by creating processes, which can be quickly constructed and accessed, making data management easier.

[0049] S3. Identify all remote service access processes, select a target remote service access process from them, and grant the target remote service access process write permission; send the write request sent by the target remote service access process to the operating system serial port through the BMC serial port, so that the operating system performs a corresponding write operation after receiving the write request through the operating system serial port.

[0050] Multi Clients are given permission levels, and the client with instance=1 is given read and write permissions, while other clients are only given read permissions. This has the advantage of preventing multiple people from modifying OS data at the same time, which may cause unknown execution errors, and also ensuring data security.

[0051] S4. Realize the one-click opening or closing function of SOL Multi Clients through IPMI commands. For remote server management that does not require multi-person collaboration, after disabling this function, only one SOL Client will be allowed to be opened.

[0052] Specifically, the present invention sets a state control option for the communication connection link and controls the on / off state of the communication connection link through the state control option, thereby realizing control of whether to enable the function.

[0053] like Figure 2 As shown, the system 200 includes:

[0054] The serial port connection unit 210 is used to receive operating system data from the BMC serial port, and the BMC serial port is communicatively connected with the operating system serial port;

[0055] The data forwarding unit 220 is used to parse the target address of the operating system data and send the operating system data to the corresponding remote service access process according to the target address.

[0056] Optionally, as an embodiment of the present invention, the system further includes:

[0057] A permission setting unit, used to identify all remote service access processes, select a target remote service access process from them, and grant the target remote service access process write permission;

[0058] The operation execution unit is used to send the write request sent by the target remote service access process to the operating system serial port through the BMC serial port, so that the operating system executes the corresponding write operation after receiving the write request through the operating system serial port.

[0059] Optionally, as an embodiment of the present invention, the serial port connection unit includes:

[0060] The link building module is used to build a communication connection link between the BMC serial port and the operating system serial port from the software layer.

[0061] Optionally, as an embodiment of the present invention, the system further includes:

[0062] The function control unit is used to set the state control option of the communication connection link, and control the on / off state of the communication connection link through the state control option.
