Detailed Description

Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood that the description is illustrative only and is not intended to limit the scope of the present disclosure. In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present disclosure.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The terms "comprises," "comprising," and the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.

All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It is noted that the terms used herein should be interpreted as having a meaning that is consistent with the context of this specification and should not be interpreted in an idealized or overly formal sense.

Where a convention analogous to "at least one of A, B and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B and C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.). Where a convention analogous to "A, B or at least one of C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B or C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.).

In order to facilitate understanding of the technical solution of the present disclosure, a server, a cabinet, and problems thereof in the related art will be first described.

Fig. 1 schematically shows a structural diagram of a cabinet and its components in the related art.

The related art can implement out-of-band management of servers by exclusively configuring one server with an out-of-band IP address (out of band, which refers to management of servers using a network physically or logically isolated from a production service network). For example, in an advanced telecommunications computing architecture system, servers may be implemented in the form of blades. In the fields of key business processing represented by large databases, etc., servers may exist in the form of rack servers. In any form, the basic architecture of the server is the same, and the server can be divided into two parts, namely a HOST (HOST) and a Baseboard Management Controller (BMC), as shown in fig. 1. The HOST is a computing node in the server, is a main body for completing system service processing, and is composed of one or more CPUs, a bridge, a memory, a hard disk, an interface card, and the like, and is also called a load (payload) part. BMC is a management node on the server, and realizes the functions of power-on and power-off of HOST, firmware version upgrading, logging, monitoring, alarming, fan speed regulation, power control and the like through an out-of-band management channel, so that the reliability and maintainability of HOST can be effectively improved. The BMC is an out-of-band management module independent of a CPU (central processing unit), a BIOS (basic input output system) and an operating system of the server, and can monitor and manage the server as long as the power is switched on no matter whether the server is in a starting state or not.

In a server room of a data center, dozens of servers can be placed in one cabinet to form one device, such as a whole cabinet server. In order to facilitate out-of-band management of each server, an IP address (i.e., an out-of-band IP address) needs to be allocated to each BMC.

As shown in fig. 1, a plurality of cabinets 1, 2, … … may be included in a server room. Multiple servers may be included in each enclosure, such as servers 11, 12, 13, etc. in enclosure 1, and each server may include HOST and BMC for out-of-band HOST management based on BMC. However, this requires that each server is allocated an out-of-band IP address, which requires more network resources.

In addition, in order to facilitate the knowledge of the location information of each server, the tag attached to the server (such as RFID11, RFID21, etc. in fig. 1) can be automatically identified through RFID technology to obtain the location information of the device and synchronized into the device resource management system, so that the user can obtain the location information of the server by querying the device resource management system. However, the accuracy of the RFID technology in accurate positioning is low, and thus the centimeter-level high-accuracy requirement in the U-bit positioning scene cannot be met. In addition, electromagnetic interference exists in the machine room, the field intensity change is large, the RFID signal transmission is influenced, and the high reliability of users cannot be met. In addition, attaching an electronic tag to each server results in higher labor and time costs.

The embodiment of the disclosure provides a circuit board and a cabinet, the circuit board includes a plurality of data interfaces, each data interface has a one-to-one correspondence with a height (U bit) of the cabinet, for example, each U bit corresponds to one data interface, the interface can be electrically connected (e.g., wired) with an asset (electronic equipment such as a network device and a server) through an interface such as a network port or a USB, and the circuit board can obtain a position (U bit) of the asset through the data interface connected with the asset. Asset related information may also be obtained over the connection (thereby facilitating out-of-band management). For example, a host is arranged on the cabinet and connected with the circuit board through a data line (such as a USB interface, a network port, etc.), the host has an independent IP address and is connected to the data center network, and the operation and maintenance personnel can obtain information such as U bit, configuration, state, etc. of assets inside the cabinet through the host of the cabinet and realize some simple management operations.

On one hand, the circuit board and the cabinet provided by the disclosure can save a large amount of network resources, for example, an out-of-band IP address does not need to be configured for each server, and only an IP needs to be configured for one cabinet host to manage all servers (for example, 15 to 20 servers or more) in the whole cabinet. On the one hand, on the basis of reducing the labor cost and the time cost, the accuracy of U-level positioning of the server can be realized, the influence of electromagnetic interference on positioning is reduced, and the reliability of a positioning result is improved.

Fig. 2 schematically illustrates a schematic diagram of an application scenario applicable to a circuit board and a cabinet according to an embodiment of the present disclosure. It should be noted that fig. 2 is only an example of a system architecture to which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, and does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.

As shown in fig. 2, the computer room may include a plurality of cabinets 1, 2, etc., each cabinet may include a plurality of electronic devices (for example, the cabinet 1 includes servers 11, 12, 13, etc.), each server uses a production service network to perform service-related data transmission, and uses an upper computer (for example, the upper computer 1 or 2, etc.) or a circuit board (for example, the circuit board 1 or the circuit board 2, etc.) to perform asset location and out-of-band management on each server. For example, the circuit board comprises a plurality of first interfaces for connecting with the electronic devices, each first interface corresponds to one U bit, so that the upper computer can determine the U bits occupied by the electronic devices connected with the upper computer based on the interface information (the characterized U bits) of the first interfaces, realize accurate positioning of the U level, and perform out-of-band management on the electronic devices based on the positioning result. In addition, the circuit board can be in wired connection with the electronic equipment, so that the influence of electromagnetic interference can be effectively reduced.

It should be understood that the number of electronic devices, cabinets, circuit boards, and upper computers is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.

Fig. 4 schematically shows a structural schematic diagram of a circuit board according to an embodiment of the present disclosure.

As shown in FIG. 4, the circuit board 4 may be disposed in a cabinet including M cabinet heights based on standard units, the cabinet being used for disposing electronic devices such as servers 1-20, and the circuit board 4 may include a first interface 41 and a second interface 42. In the present embodiment, the standard unit is a unit (Uint, abbreviated as U) for characterizing the external dimensions of the electronic device. Taking the example where the electronic device is a server, 1U may be 4.445 CM.

When the cabinet is provided with N electronic devices, the W first interfaces 41 are electrically connected to the N first interfaces 41 in the W first interfaces 41, respectively, where there is a correspondence between the height of the cabinet and the first interfaces 41, values of M, W and N are positive integers, and a value of W is less than or equal to M and greater than or equal to N.

The number of the height (U bit) of the cabinet and the number of the first interfaces can be the same or different. As shown by the dashed double arrow in fig. 1, the cabinet height of the cabinet includes: 1U-45U, the number of first interfaces can be 45, and the rack height corresponds to the first interface 41 one by one. It should be noted that the distance between adjacent first interfaces 41 may be 1U, or may not be 1U, and is not limited herein. As another example, there is one corresponding cabinet height for each first interface 41. As shown by the solid line with the double arrows in fig. 1, in the up-down direction, the first interface corresponds to 45U, the second first interface corresponds to 43U, the third first interface corresponds to 41U, the fourth first interface corresponds to 39U, and the lowermost first interface corresponds to 1U. Thus, the position information of the electronic device can be determined based on the U bit of the first interface electrically connected with the electronic device.

The logic circuit is used for determining the height of the cabinet occupied by the designated electronic equipment based on the interface information and the corresponding relation of the first interface electrically connected with the designated electronic equipment. For example, if the electronic device is electrically connected to the first interface corresponding to 45U, it may be determined that the electronic device occupies at least 45U of the cabinet height.

The second interface 42 is used at least for outputting the height of the cabinet occupied by the specified electronic equipment.

In the present embodiment, the first interface standard supported by the first interface 41 is compatible with the second interface standard supported by at least one interface provided by the N electronic devices.

For example, the types of the first interface 41 and the second interface 42 may be the same or different, and the type of the second interface 42 and the type of the interface of the electronic device may be the same or different. First interface 41 and second interface 42 include, but are not limited to, an I2C interface, a parallel interface, a serial computer bus express (PCIe) interface, a Universal Serial Bus (USB) interface, a Serial Peripheral Interface (SPI), and the like.

In another embodiment, the logic is further configured to manage the N electronic devices out-of-band. Or the second interface is also used for information interaction so as to carry out-of-band management on the N electronic devices based on the information. The out-of-band management is realized by carrying out centralized integrated management on the computer room network equipment and the server equipment primary computer room power supply system through a special management channel independent of a data network, the data and the management do not share the same physical channel any more, and the two networks are completely independent and do not influence each other. For example, a BMC module for implementing out-of-band management may be integrated on a circuit board. Also for example, the electronic devices are separately managed out-of-band by a host connected to the second interface.

The first interface of the circuit board and the height of the cabinet have a corresponding relation, so that the height of the cabinet where the electronic equipment is located can be determined based on the first interface and the corresponding relation used by the electronic equipment, the electromagnetic interference is small, the accuracy and the reliability of the determined position information of the electronic equipment are effectively improved, the accuracy and the reliability of asset management are improved, and meanwhile, the labor cost and the time cost can be effectively reduced.

For example, there may be 6 or more outlets to meet the multi-server power requirements. Arranging the wire device: 19 "standard organizer. The mounting structure can be selectively mounted in the cabinet for use and mounted on the vertical beam of the cabinet. Wire arranging ring: the wire arranging device in use is arranged on the vertical beam of the cabinet, so that the installation and the disassembly are very convenient, and the number and the position of the use can be adjusted at will.

The L-shaped bracket can be used with a cabinet, is used for installing 19' standard equipment in the cabinet, and is mainly used for installing a rack-mounted server. The blind plate is used for shielding vacant positions in 19' standard cabinets and has various specifications such as 1U, 2U. The conventional blind plates are 1U and 2U. The cross beam and the vertical beam are used for expanding the installation space in the cabinet and can be freely adjusted according to the size of equipment so as to be convenient to install and detach. Mounting nuts (e.g., square nuts) are used for mounting and securing electronic equipment within the cabinet. The keyboard drawer is used for installing a standard computer keyboard, such as a 19' size computer keyboard. The keyboard drawer can be used in cooperation with the sliding tray.

The fan unit can be installed at the top of the cabinet and used for exhausting air in the cabinet, and the temperature in the cabinet is effectively reduced. The height of the rack type fan unit can be 1U, and the rack type fan unit can be installed at any cabinet height position in a 19' standard cabinet, and the number of the rack type fan unit can be configured according to the number of heat sources in the cabinet.

The mesh front door is helpful for solving the heat dissipation problem of electronic equipment in the cabinet, so that the equipment in the cabinet can operate better. For example, the ventilation area of the ventilation holes at the front door of the mesh is not less than 70% of the area of the cabinet door, which can provide the best horizontal ventilation, and furthermore, the electronic equipment can be conveniently checked through the mesh to confirm the state of the server.

The circuit board comprises W first interfaces, a logic circuit and a second interface.

The logic circuit is used for determining the height of the cabinet occupied by the designated electronic equipment based on the interface information and the corresponding relation of the first interface electrically connected with the designated electronic equipment. The second interface is at least used for outputting the height of the cabinet occupied by the appointed electronic equipment.

In one embodiment, the height dimension of the designated electronic device comprises a positive integer multiple of standard units.

Fig. 6 schematically illustrates a schematic of a cabinet height and standard units according to an embodiment of the disclosure.

As shown in fig. 6, the cabinet 1 may or may not be provided with a scale longitudinally, but the heights of the cabinets of the cabinet 1 are in one-to-one correspondence with the scales of the virtual scale.

As shown in fig. 7, the height dimension of the server is 2U specification, and the top and bottom of the server correspond to one cabinet height (U bit), respectively, when the server is installed. In order to avoid the problem that the manufactured circuit board is too large and causes high cost, the size of the circuit board can be smaller than 45U, but 45 first interfaces can be arranged on the circuit board, and the height of the cabinet corresponding to each first interface is marked, so that a user can accurately connect the server and the circuit board when the server is installed or debugged.

In one embodiment, when the height dimension of the specified electronic equipment is larger than a standard unit, the height of the cabinet occupied by the specified electronic equipment is determined according to a preset rule. For example, the preset rule includes any one of: a maximum value among the rack heights occupied by the designated electronic device, a minimum value among the rack heights occupied by the designated electronic device, or all values among the rack heights occupied by the designated electronic device. For example, the top of the electronic device is level with the height of the cabinet corresponding to the occupied first interface. For another example, when the plurality of electronic devices occupy two first interfaces, the electronic devices may be electrically connected to the first interface located below. The electronic equipment in the cabinet is arranged by using a uniform preset rule, so that the accuracy of the height of the cabinet occupied by the determined electronic equipment is improved.

And the second interface of the circuit board is electrically connected with the upper computer. The upper computer can be used as a BMC module of each server.

For example, 20 virtual machines may be included in the upper computer, each virtual machine implementing the function of the BMC module for one server. In particular, virtualization software may be used to virtualize a plurality of logical BMC modules from the virtualization software, each providing out-of-band management support for one server.

For another example, the upper computer includes a plurality of BMC modules, and each BMC module operates independently and does not interfere with each other. The interface of each BMC module is electrically connected with a server to realize out-of-band management.

For another example, BMC modules may be disposed on the circuit board, and each BMC module corresponds to one first interface to implement out-of-band management.

The out-of-band management of a plurality of electronic devices in one cabinet is realized through a circuit board or an upper computer, and the connection with a background maintenance host through an out-of-band IP address can be realized, so that the dynamic configuration can be realized in an operation and maintenance background. If an electronic device is newly added in the cabinet, a BMC module (logical or physical) can be dynamically allocated to the electronic device based on the upper computer, so that flexible allocation and dynamic adjustment of out-of-band management are facilitated. Meanwhile, a large amount of network resources can be saved, all servers (such as 15-20 servers) in the whole cabinet can be managed only by configuring an out-of-band IP address for the upper computer of the cabinet, and the utilization rate of the network resources is greatly improved, for example, more than 90% of the out-of-band IP addresses can be saved.

In one embodiment, the upper computer (e.g., host) on the top of the cabinet is connected to the circuit board (e.g., integrated motherboard) via a USB interface, the integrated motherboard has a length of 45U, each U corresponds to a corresponding U bit of the cabinet, and each U is provided with a data interface that can be wired to an electronic device (e.g., switch, server, etc.) via a network port or a USB interface. After the electronic equipment is installed, the electronic equipment is connected with an interface of a corresponding U bit (such as the highest U bit of the electronic equipment in a cabinet) on an integrated mainboard, the integrated mainboard can obtain the related information (U height) of the electronic equipment through the connection, and after the integrated mainboard identifies the electronic equipment, the actual position of the electronic equipment in the cabinet is judged according to the U height of the electronic equipment and the interface position connected with the electronic equipment, so that the U bit information of the electronic equipment is obtained, and the electronic equipment can be managed out of band through the connection. The top of the cabinet is provided with a host which is connected with the integrated mainboard through a data line (USB interface), the host is provided with an independent out-of-band IP address and is connected with the data center network, and operation and maintenance personnel can obtain information such as U bit, configuration, state and the like of electronic equipment in the cabinet through the host of the cabinet and realize some management operations.
