Description

Technical Field

[0001] The present application relates to the field of server technology, for example, to a server based on a VPX architecture. Background Art

[0002] Blade servers play an important role in modern data centers with their high availability and high-density computing features. However, there are some problems with the reinforced VPX servers currently on the market, especially in harsh working environments. The main problem lies in the chassis design. The blade server unit panels of the open chassis are directly exposed and lack protection, making them easily damaged in harsh environments such as humidity, heat, and salt spray. Although the closed chassis provides better protection, it makes it difficult to observe the operating status of the equipment, making fault location and repair difficult and costly.

[0003] At present, the most similar technical solution to the present invention is to use metal plates to encapsulate the reinforced server housing to improve the equipment's ability to resist harsh environments. However, this method makes it impossible to directly observe the operating status of the blade server unit during equipment operation, and the reinforced metal plates of the entire chassis need to be disassembled for maintenance, which increases the complexity and cost of maintenance.

[0004] In addition, existing high-density servers have problems such as easily damaged cooling fans, difficulty in expanding the capacity of fully enclosed machines, and difficulty in obtaining health information of equipment inside the chassis.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0047] Combination Figure 4 As shown, the embodiment of the present disclosure provides a server based on VPX architecture, the whole machine can be configured to accommodate 6 functional blades (5HP), with a built-in power supply. The blades are interconnected by bus and star network data to form a streamlined computer system.

[0048] The server mainly consists of the following parts:

[0049] Chassis modules, backplanes, and power blades: As unit-level infrastructure, they provide physical load-bearing, structural reinforcement, centralized heat dissipation, centralized power supply, etc. At the same time, they meet the technical requirements of resistance to harsh environments (wide temperature range, vibration resistance, three protections), and electromagnetic compatibility (shielding, filtering), and have the characteristics of light weight, low noise, and energy saving.

[0050] General recording and storage blade (storage blade): responsible for the recording, management, playback and transfer of radar data, supporting file, disk block, database read and write storage and playback services. Provide 40G / 10G Ethernet interface to carry business data, and Gigabit Ethernet interface to carry management data. Adopt open computer architecture, software and hardware can be tailored and expanded, and use domestic Feiteng processor chips and basic software.

[0051] General-purpose intensive computing blade (computing blade): Applicable to all types of radar general-purpose domestic computer chassis, providing 40G Ethernet interface to carry business data and Gigabit Ethernet interface to carry management data. It adopts open computer architecture, and the software and hardware can be tailored and expanded, using domestic Feiteng processor chips and basic software.

[0052] 40G Ethernet switch blade (reserved): adopts 6UVPX form factor design, based on VPX bus architecture, and improves data exchange capability through standardized and modular design and integrated architecture. The hardware includes key components such as Loongson 2K1000 processor, Centec CTC8096 switch chip, BMC module, etc.

[0053] Rear IO board: including computing rear IO board, storage rear IO board, and switching rear IO board, which are used to connect the interfaces of each blade with external devices.

[0054] On this basis, the server can adopt the 19-inch rack standard, 5U height chassis design, modular and standardized design, and anti-harsh environment reinforcement technology. The internal module adopts the front horizontal insertion form and follows the 6U 5HPVPX standard design specifications, follows the mainstream VPX and other design specifications at home and abroad, pays attention to serialization and standardization, and ensures that the same hardware platform is interchangeable and upgradeable in structural design, and adopts anti-harsh environment reinforcement technology. The whole machine adopts the rear outlet mode, and the power switch and indicator light are placed on the front panel. The whole machine is installed in a standard 19-inch cabinet, the back of the cabinet is against the wall, and the upper and lower air ducts are reserved between the equipment and the wall.

[0055] The computing blade is equipped with Feiteng processor to achieve high reliability, high bandwidth and high performance computing.

[0056] The firmware layer includes BIOS, BMC and CPLD, which provide hardware setting, control and monitoring functions.

[0057] Equipped with the domestic Kirin operating system, it provides underlying drivers for the domestic Feiteng processors and supporting chips, optimizes the domestic processor architecture, and provides core functions such as task scheduling and clock management.

[0058] The server disclosed in the present invention improves the overall data processing capability through high integration and modular design. The modular design can simplify the maintenance process and reduce maintenance costs. The design of resistance to harsh environments and electromagnetic compatibility ensures the stable operation of the system. The fully localized design enhances the information security protection capability.

[0059] This type of server can meet the comprehensive needs of radar general-purpose computers in information processing, data storage, computing expansion and information security, and provides strong technical support for applications in related fields.

[0060] The intelligent management system consists of a switch management system and a blade management subsystem, which can realize comprehensive monitoring of the operation status and health management of the entire system and each blade. The switch management system is responsible for collecting and managing the information of all blades in the information processing server; the blade management subsystem is responsible for collecting and managing the information of each blade.

[0061] The backplane uses the IPMB bus for out-of-band management, supports high-speed Ethernet interconnection between servers, and realizes resource sharing and data interconnection.

[0062] like Figure 5 , 6 As shown in the figure, the characteristics of the intelligent management system architecture and topological relationship architecture are as follows:

[0063] 1) Adopt the three-level fine-grained management mode of "blade (MCU / BMC)-computer chassis (ChMC)-radar (RMC)";

[0064] 2) Supports active and passive dual-mode management solutions for multiple protocols (IPMI).

[0065] Optionally, the switching blade provides 20 40G switching ports to the outside, including 16 Ethernet interfaces, of which 1 is a BMC management network port. This interface is responsible for reporting blade health status information when the system is operating normally or the blade fails. The 15-way switching chip output Gigabit network port includes 3 Gigabit SGMIIs and 12 Gigabit 1000BASE-X. The Gigabit SGMII is used for rear output, and the Gigabit 1000BASE-X can be used for interconnection between blades or switching cascades.

[0066] Optionally, when the switching blade is inserted, the switching blade is responsible for managing the operating status and health of the entire system and each blade, and provides corresponding function libraries and programming interface definition documents; when the switching blade is not inserted, the computing blade inserted in the set slot is responsible for managing the operating status and health of the entire system and each blade; each blade server unit outputs 1 Gigabit network and connects to the business network, outputs 2 IPMBs and manages the bus.

[0067] As an example, each blade server unit is equipped with a built-in intelligent management chip (BMC), which is connected to the sensors in the blade server unit module through multiple interfaces including at least ADC (analog-to-digital converter), I2C (integrated circuit bus), and GPIO (general input and output), so as to obtain the voltage, current and temperature information of the blade server unit module in real time; the intelligent management chip in each blade server module is also connected to the CPLD (complex programmable logic device) through the GPIO interface, so as to control the working state of the blade server module according to the acquired sensor information; the blade management subsystem is provided with a central management unit, which communicates with the intelligent management chip in each blade server module through redundant I2C channels and IPMB (intelligent platform management bus) protocol to collect sensor data and FRU (field replaceable unit) information of each blade server module; the central management unit is also provided with a Gigabit IPMI (intelligent platform management interface) management network output port, which is used to transmit the collected sensor data and FRU information through the network for remote monitoring and management.

[0068] like Figures 1 to 3 As shown, in some embodiments, the chassis is provided with an openable and closable door structure; the blade server unit and the fan module are installed in the chassis, and both the blade server unit and the fan module are hot-swappable structures, and the blade server unit corresponds to the position of the door structure, which is convenient for taking and placing the blade server unit.

[0069] As an example, the front and rear panels of the whole machine of the present invention both adopt a flip-over door design, so that the insertion and removal of a single card-type device are very convenient.

[0070] Optionally, the air inlet of the chassis is located at the first end of the first panel, and the air outlet is located at the second end of the second panel; the air inlet and the air outlet are located at diagonal positions; the air duct of the chassis is a Z-shaped horizontal air duct structure with air flowing in and out at the rear.

[0071] Optionally, an indicator light is provided on the fan module and / or the blade server unit, and when the intelligent management system detects that a failure occurs in the fan module and / or the blade server unit, an alarm is given through the indicator light;

[0072] At least part of the panel of the chassis is a transparent panel, and the transparent panel is used to observe the operating status of the blade server unit and the fan module. When the fan module fails, the fan module can be directly removed from the chassis.

[0073] It is understandable that the high heat generated by the high density causes the cooling fan inside the chassis to become a vulnerable component. The chassis in the present invention can automatically detect faults in the fan module and alarm through an indicator light when the fan fails. At the same time, the fan module is hot-swappable, which greatly reduces the maintenance cost and cycle of the fan. The expansion of the capacity of a fully enclosed machine is also an extremely cumbersome issue.

[0074] In addition, in order to meet higher requirements for resistance to harsh working environments, general reinforced server casings are encapsulated with metal plates for reinforcement, but this brings about the problem that the operating status of the blade server unit cannot be visually observed during the operation of the equipment. The maintenance of card-type devices requires the removal of the reinforced metal plates of the entire chassis before maintenance. In the present invention, the front panel of the entire chassis is designed with transparent glass, and the equipment operating components can visually observe the operating status of the equipment through the glass.

[0075] The beneficial effects of the present disclosure are:

[0076] Localization of software and hardware: Achieve 100% localization of software and hardware to enhance information security and independent controllable capabilities.

[0077] Modular cooling fan design: supports modular plug-in and pull-out, facilitating fan maintenance and replacement and improving maintenance efficiency.

[0078] Innovative air duct design: The Z-shaped horizontal front-in and rear-out air duct design meets the installation requirements of narrow cabinets and improves heat dissipation efficiency.

[0079] Sealed and visual design of the entire chassis: While maintaining the airtightness of the entire chassis, the front panel adopts a transparent glass design to achieve visual monitoring of the equipment's operating status.

[0080] Fan fault detection and alarm: Integrated fan fault detection and alarm functions to respond promptly and protect the server from potential damage.

[0081] Improve system performance and reliability: Through highly integrated design, efficient cooling solutions and intelligent management systems, data processing capabilities and system reliability are significantly improved.

[0082] Enhance information security and independent controllability: Realize complete localization of software and hardware, and enhance information security protection capabilities and independent controllability.

[0083] Reduce maintenance costs: Modular design and visual monitoring reduce maintenance difficulty and costs, and improve the maintainability of the system.

[0084] Flexible expansion and interconnection: The backplane interconnection topology architecture facilitates capacity expansion and realizes resource sharing and data interconnection between servers.

Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless explicitly required, individual components and functions are optional, and the order of operations may vary.
