Server user interface panel, server, use method and workstation
Technical Field
The invention belongs to the technical field of user interface panel hardware design, and particularly provides a server user interface panel, a server, a use method and a workstation.
Background
With the continuous rise and development of cloud computing technology and related derivative technology and products, the traffic volume of the internet industry gradually shows a explosive growth. The demand of server nodes as physical carriers of virtual data is increasing. As a huge industry chain, the quality of the server has not only been the indexes of the overall node operation, such as high performance, high efficiency, low power consumption, etc., which are linked with the service efficiency, but also includes the performance of the whole series of processes from factory to delivery to after-sales, where a standard RAS (Reliability, Availability, Serviceability) commonly used by firmware can be borrowed. For the hardware field, in the design process at ordinary times, attention is usually focused on reliability and availability, and similarly, how to improve the working performance of the server, reduce transmission delay, reduce performance bottleneck and the like is emphasized, but serviceability is ignored. The serviceability is that the interactivity presented by the whole server product facing to users or operation and maintenance personnel is friendly, in short, the operation is simpler, the instruction is simpler, the maintenance is more convenient, and the structure is more uniform.
For the above characteristics, the optimization design is generally performed in a software manner, so that an operator can easily complete service operation, and an operation and maintenance worker can better perform maintenance on a node by going to an operating system. For the hardware field, the serviceability (maintenance) of the server node is generally improved by a structural design, such as optimizing a guide rail design of a cabinet, optimizing a self-locking structure of a hard disk tray, or increasing an installation structure of a fan module of the server node. For board level design, CBB (Common Building Block) design is generally adopted, and Follow general design is used to reduce design complexity and improve product reusability. However, for the existing general design, there are still many designs that can optimize for "serviceability", for example, for the front panel design of the server for the user interaction expansion interface, the existing general design usually adopts the form of using hangers at both sides of the server node to design two PCB boards to realize the basic expansion of the external interaction interface; the external IO interfaces are placed in the idle spaces of the front panel and the rear panel as far as possible under the condition that the main functions (the hard disk module, the PCIe module and the like) are complete.
In order to reserve a maintenance interface, a traditional VGA interface is reserved in an IO interface, but the interface is large in size and occupies a large PCB area, an external serial port channel is not reserved in an external interface, and once a node fails, only in-band Debug can be used or cover opening maintenance can be carried out.

Detailed Description
For board level design, CBB (Common Building Block) design is generally adopted, and Follow general design is used to reduce design complexity and improve product reusability. However, for the existing general design, there are still many designs that can optimize for "serviceability", for example, for the front panel design of the server for the user interaction expansion interface, the existing general design usually adopts the form of using hangers at both sides of the server node to design two PCB boards to realize the basic expansion of the external interaction interface; the external IO interfaces are placed in the idle spaces of the front panel and the rear panel as far as possible under the condition that the main functions (the hard disk module, the PCIe module and the like) are complete.
In order to reserve a maintenance interface, a traditional VGA interface is reserved in an IO interface, but the interface is large in size and occupies a large PCB area, an external serial port channel is not reserved in an external interface, and once a node fails, only in-band Debug can be used or cover opening maintenance can be carried out. In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a server user interface panel, where a server motherboard is provided with a PCH and a BMC, and the panel is provided with a USB-C interface, and the USB-C interface is connected to the PCH and the BMC on the server motherboard through a hardware interface link;

The server is designed differently, the USB-C interface is arranged on the front panel or the back panel of the server, and when the USB-C interface is generally designed on the front panel, the middle core portion of the front panel is usually configured to be a hard disk module and some optional components, such as a network card, an expansion card, and the like, according to a specific use scenario and a package configuration of the server. While some basic function buttons or external user interfaces are disposed on two sides, as shown in fig. 2, in this embodiment, the USB-C interface 104 is disposed on the left side, the UID 103, the LED 102, and the function button 101 are sequentially disposed at an upward position of the USB-C interface 104, and the network port 106 is disposed below the USB-C interface 104. The VGA interface and the USB interface are combined into the USB-C interface in the optimized panel, so that the PCB area occupied by the VGA is greatly reduced. The right ear loop saved in fig. 2 may be labeled with labels or server operation advice or may be an extended function panel. Considering the unattractive appearance caused by the asymmetry of fig. 2, we can also design the front panel as the mode in fig. 3, concentrate the external interface components on the upper right corner of the front panel, and set the network port 106, the USB-C interface 104, the UID 103, the LED 102, and the function buttons 101 in sequence from left to right, where the left side is the conventional hard Disk module Disk, and the lower right corner can be the PCIe module or the network card interface. At present, more and more server models select a heat dissipation mode using immersion type liquid cooling, a traditional left and right hanging lug mode may interfere with a suspension module in structure, the problem can be well avoided by adopting a panel design shown in figure 3, and a large design allowance is reserved for the design of an immersion type heat dissipation chassis.
As shown in fig. 4, an embodiment of the present invention provides a server user interface panel, where a server motherboard is provided with a PCH and a BMC, and the panel is provided with a USB-C interface, and the USB-C interface is connected to the PCH and the BMC on the server motherboard through a hardware interface link;

The downlink signal interface of the independent controller chip is connected with the USB-C interface through an electrically programmable fuse;
and the electrically programmable fuse is used for protecting the USB-C interface.
The panel is also provided with an optional USB-C interface, a downlink signal interface of the independent controller chip is connected with the optional USB-C interface through an electrically programmable fuse, and the part in a dotted line frame in the figure 4 is a connecting line of the optional USB-C interface.
The hardware interface link also comprises a signal conditioning chip which is arranged between the independent controller chip and the electrically programmable fuse Efuse and is used for improving the signal transmission quality. The independent controller chip and the signal conditioning chip are respectively connected with a FLASH through the SPI. A USB2.0 interface chip is integrated in the independent controller chip, and the independent controller chip is connected with a USB-to-Uart chip through a USB2.0 interface; the USB-to-Uart chip is used for ascending a Uart interface, the Uart interface is connected with a programmable logic device, the USB-to-Uart chip is used for descending a USB interface, and the USB interface is connected to the independent controller chip and used for accessing an internal serial port through an external USB-C interface.

In this embodiment, the PCIe, USB, and DP may be integrated in the same physical channel, that is, Type-CIO, by using Thunderbolt technology based on an independent Controller chip (secret TBT4 Host Controller chip) Maple Ridge JHL8340/JHL8540 (single-way or double-way), and finally, the purpose of physically merging the front panel user interfaces of the servers is achieved.
The USB-C interface is used for transmitting video signals through a DP protocol, and at present, most of monitors used for maintenance or monitoring in a machine room are old monitors only supporting a VGA interface. For this problem, there are two solutions, one of which is that since the frequency of the display use requirement is not very high during the operation and maintenance process, a display supporting the DP interface can be used; secondly, considering that the use scene is not the use of the conventional service, the operation and maintenance personnel can be provided with a DP-to-VGA adapter cable to solve the problem.
A fixed USB-C interface and an optional USB-C interface are designed in the panel. The reason for this is that the requirement for the keyboard and mouse can be fully realized by the virtual KVM in consideration of the use scenario, and of course, if the convenience of operation and maintenance is the first priority, two USB-C interfaces are suggested. As shown in fig. 2, the hard Disk module Disk is disposed in the middle, the USB-C interface 104 is disposed on the left in this embodiment, the UID 103, the LED 102, and the function button 101 are sequentially disposed at the upward position of the USB-C interface 104, and the USB-C vault 105 and the internet access 106 are disposed at the lower position of the USB-C interface 104. The VGA interface and the USB interface are combined into the USB-C interface in the optimized panel, so that the PCB area occupied by the VGA is greatly reduced. The right ear of the hanging shown in the left-hand side of fig. 2 is an optional function block area 107, which may be labeled with labels or server operation advice or may be an extended function panel. Considering the unattractive appearance caused by the asymmetry of fig. 2, we can also design the front panel as the mode in fig. 3, concentrate the external interface components on the upper right corner of the front panel, set up the network port 106, USB-C interface 104, UID 103, LED 102, function button 101 sequentially from left to right, set up the selectable USB-C interface 105 below the USB-C interface 104; the left side is the conventional hard Disk Module Disk, and the right bottom side can be a PCIe Module or a NIC Module. At present, more and more server models select a heat dissipation mode using immersion type liquid cooling, a traditional left and right hanging lug mode may interfere with a suspension module in structure, the problem can be well avoided by adopting a panel design shown in figure 3, and a large design allowance is reserved for the design of an immersion type heat dissipation chassis.
