The serial number is a unique identifier that distinguishes and identifies different servers.

In this embodiment, a further method for positioning a service server is further provided, and fig. 4 is a flowchart three of the method for positioning a service server according to the embodiment of the present application, as shown in fig. 4, the method includes the following steps:

step S402, responding to the positioning instruction, sending server position information to the access point, wherein the position information of the service is used for indicating the installation position of the service server in the target cabinet.

Alternatively, a photoelectric encoder (a dial encoder) may refer to a sensor that converts a mechanical geometric displacement on an output shaft into a pulse or digital quantity through photoelectric conversion. For example, a dial wheel on a digital camera is a photoelectric encoder, and when the dial wheel is dialed, different numerical values are displayed on a liquid crystal screen. The photoelectric encoder used in the invention is a similar thumb wheel encoder.

Optionally, the user dials a photoelectric encoder (dial encoder) on the positioner, sets a number equal to the actual U-position of the server to be positioned, for example, the 18 th U of the rack to be positioned is set as the server, sets the number 18 through the photoelectric encoder, displays the number in real time through a liquid crystal display on the positioner, and stores the number in a flash memory medium of the positioner.

In this embodiment, a method for positioning a service server is provided, and fig. 5 is a schematic diagram of a method for positioning a service server according to an embodiment of the present application, as shown in fig. 5, the method mainly includes the following steps:

The user inserts the locator into the USB interface of the server to be positioned, the locator is electrified and automatically started at the moment, and power is supplied subsequently by the USB interface. The WIFI chip of locator oneself starts and is connected to the AP in the rack automatically. One AP is deployed in each cabinet and connected to the backend management server through a dedicated wired network (consisting of network cables and switches).

Step S502: the user dials the photoelectric encoder (dial encoder) on the positioner, sets the number which is equal to the actual U position of the server to be positioned, for example, the 18 th U position of the server to be positioned is set, the number 18 is set through the photoelectric encoder, the number is displayed in real time through the liquid crystal screen on the positioner, and the number is obtained and stored in the flash memory medium of the positioner.

Step S503: the back-end management server executes a task of obtaining the serial number of the server in batch at regular time (for example, at a designated time every morning), dispatches an Operating System (OS) of each server to be positioned through a batch tool to read the serial number of a server mainboard, and writes the serial number into a flash memory medium of the positioner. The serial number is a unique identifier that distinguishes and identifies different servers.

Step S504: the locator sends the U bit, serial number stored in the locator flash media to the AP in the cabinet via the WIFI link established in step 101, in a format similar to [ U bit, serial number ], e.g., [18, sn12345].

Step S505: the AP forwards the information generated in step 104, together with the enclosure name, to the backend management server in a format similar to [ enclosure name, U bit, serial number ], e.g., [ W6101B-a01,18, sn12345]. The backend management server generates a piece of server location information after adding a time stamp to the received information, for example [ 2022-01-10, w6101b-a01,18, sn12345], and stores the server location information in a database of the backend management server, thereby achieving server location.

Step S506: the method comprises the steps that a back-end management server initiates U-bit check at regular time (for example, at a designated time every morning) (or the locators automatically execute according to a preset period), WIFI fingerprints (WIFI signal strength sensed by the locators) of each locator are collected, an actual U-bit range of each locator is estimated through a preset algorithm, for example, 10-20 indicates that the locator may be located in the range from 10U to 20U of a cabinet, the range value is compared with the manually set U-bit number uploaded by the locator, and if the manually set U-bit number is out of the range, an exception is prompted to an operation and maintenance person (for example, a designated field of a database is marked, or an email prompt is automatically sent and the like).

It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than here.
