Description

Technical Field

[0001] The present invention relates to the technical field of power distribution, and more particularly to a server platform. Background Art

[0002] With the rapid development of technologies such as cloud computing, big data, and artificial intelligence, the hardware architecture of hyperscale data centers is gradually changing. In traditional data center architectures, components such as CPUs, memories, storages, and networks are included, but it is now generally recognized that the CPU is no longer the best location for running infrastructure functions. If functions such as virtual machine monitors, routing, load balancing, and IO-intensive security functions such as deep packet inspection, data storage encryption, and decryption are to be supported, a large amount of processing power is required. For hyperscale data centers, approximately half of the CPUs are used for non-revenue-generating tasks. Smart network cards can take on most of the heavy work, freeing up the CPU to focus on revenue-generating application processing.

[0003] Driven by the wave of cloud computing and big data, the evolution of server architectures is changing with each passing day. For example, as an OCP (OpenCompute Project) network card serves as a bridge connecting the server to the outside world, the requirements for new general-purpose servers demand that multiple external cards operate in standby power-off. In the traditional power supply scheme of the server platform, the power consumption in standby power-off is relatively low, and generally, a switching method is adopted, that is, the power consumption in standby power-off is relatively low, and standby power-off is directly used. When the device is turned on and running normally, the main power supply is switched to supply power. Although this scheme can meet the applications of general devices, with the development of the times, applications are also evolving, and the traditional power supply scheme of the server platform can no longer meet the requirements of standby power-off for high-power external cards.

Detailed Embodiments

[0026] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention with reference to the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] With the rapid development of technologies such as cloud computing, big data, and artificial intelligence, the hardware architecture of ultra-large-scale data centers is gradually changing. In traditional data center architectures, components such as CPUs, memory, storage, and networks are included. However, it is now generally recognized that the CPU is no longer the best location for running infrastructure functions. To support functions such as hypervisors, routing, load balancing, and IO-intensive security functions such as deep packet inspection, data storage encryption, and decryption, a large amount of processing power is required. For ultra-large-scale data centers, approximately half of the CPUs are used for non-revenue-generating tasks. Smart network cards can take on most of the heavy work, freeing up the CPU to focus on revenue-generating application processing.

[0028] Driven by the wave of cloud computing and big data, the evolution of server architectures is changing rapidly. For example, as the OCP (OpenCompute Project) network card serves as the bridge connecting the server to the outside world, the demand for new general-purpose servers requires multiple external cards to operate in standby power-off mode. In the traditional power supply scheme of server platforms, the standby power consumption is relatively low, and generally, a switching method is adopted, that is, the power consumption is relatively low in standby power-off mode, and the standby power is directly used. When the device is turned on and running normally, the main power is switched to supply. Although this scheme can meet the applications of general devices, with the development of the times and applications, the traditional power supply scheme of server platforms can no longer meet the demand for standby power of high-power external cards.

[0029] Based on this, a server platform provided by an embodiment of the present invention can be connected to an AC power supply through a CRPS power supply to supply power to the device end to support the standby operation of smart network cards and OCP network cards. After the AC power is connected to the CRPS power supply, the main power of the CRPS power supply is directly powered on, and the device end uses the main power of the CRPS power supply. The power chip controls whether the device end is connected to the CRPS power supply. In this method, the main power of the CRPS power supply is directly used, and the power chip is used to control the power-on time of the device end, distinguishing whether the device end uses standby power or main power, meeting the demand for standby power of servers and high-power smart network cards and OCP network cards.

[0030] To facilitate the understanding of this embodiment, a server platform disclosed in an embodiment of the present invention will be introduced in detail first.

[0031] Embodiment 1

[0032] An embodiment of the present invention provides a server platform, Figure 1 which is a structural diagram of a server platform provided by an embodiment of the present invention. As Figure 1 shown, the server platform may include the following structure: a device end 10, a power supply unit 20 (Power Supply Unit, PSU), and a power chip 30.

[0033] Among them, the power supply unit 20, the power chip 30, and the device end 10 are connected in sequence; the device end 10 includes a smart network card 115 and an Open Compute Project (OCP) network card 116; the power supply unit 20 is a Common Redundant Power Supply (CRPS).

[0034] Specifically, the CRPS is used to convert alternating current into direct current and supply power to the device end 10 by connecting to an AC power source to support the standby operation of the smart network card and the OCP network card.

[0035] For easy understanding, Figure 2 The following is a structural diagram of a CRPS provided by an embodiment of the present invention. As Figure 2 shown, the power supply unit 20, that is, the CRPS, includes a first pin 21, a second pin 22, a third pin 23, a fourth pin 24, a fifth pin 25, and a main power start control pin 26 of the power supply.

[0036] Among them, the main power start control pin 26 is directly grounded, and the first pin 21 and the second pin 22 are grounded; after the AC power is connected to the CRPS, the third pin 23 and the fourth pin 24 send out the main power, and the fifth pin 25 sends out the standby power. The device end 10 uses the main power, and the standby power is reserved.

[0037] Among them, the pin number of the first pin 21 can be B1 - B9, the pin number of the second pin 22 can be A1 - A9, the pin number of the third pin 23 can be B10 - B18, the pin number of the fourth pin 24 can be A10 - A19, the pin number of the fifth pin can be B21, and the pin number of the main power start control pin 26 of the power supply can be A21.

[0038] Among them, after the AC power is connected to the CRPS, the device end 10 uses the main power of the CRPS, and the standby power of the CRPS is reserved.

[0039] Specifically, various devices in the device end 10 control the on - time of the power chip 30 through the program of a Complex Programmable Logic Device (CPLD).

[0040] Among them, the standby power is the power that the CRPS has without control after the AC power is plugged in; the main power is the power that the CRPS has after the AC power is plugged in and controlled. The specific control can be pressing the power connection key.

[0041] Among them, the main power can be represented as P12V, and the standby power can be represented as P12V_STBY.

[0042] Specifically, the power supply chip 30 is used to control whether the device end 10 is connected to the CRPS power supply, and in the case of connecting to the CRPS power supply, control the connection time of the CRPS power supply.

[0043] Among them, the power supply chip 30 is an integrated controller and switch, with a power MOSFET and other circuits, enabling it to work independently or be controlled by a hot-swap controller. It can drive a continuous output current of up to 50A for each device at room temperature and up to 60A of continuous output current under airflow. It can limit the voltage drop by limiting the inrush current of the load when inserting the circuit board into a live power supply, and can limit the internal MOSFET current by current-limit reference input and soft-start ramp control of the gate voltage. It can not only control the timing but also play a role in circuit protection.

[0044] Among them, relevant programs can be pre-written in the CPLD to control the power supply chip 30 to distinguish standby power and main power. When the device end 10 works through standby power, the power supply chip 30 can be directly enabled. The device end 10 after such a power supply chip 30 can reach 600W, which can well meet the high power consumption of the device end 10.

[0045] In practical applications, the standby power consumption of the CRPS power supply itself is relatively low and is not sufficient to meet the simultaneous operation of the server, high-power smart network cards, and OCP network cards in the standby power form. However, the server platform provided by the embodiments of the present invention can supply power to the device end by connecting the CRPS power supply to the AC power supply to support the standby operation of the smart network card and the OCP network card. After the AC power is connected to the CRPS power supply, the main power of the CRPS power supply is directly powered on, and the device end uses the main power of the CRPS power supply. Whether the device end is connected to the CRPS power supply is controlled by the power supply chip. In this method, the main power of the CRPS power supply is directly used, and the power supply chip is used to control the power-on time of the device end, distinguishing whether the device end uses standby power or main power, meeting the standby power requirements of the server, high-power smart network cards, and OCP network cards.

[0046] Embodiment 2

[0047] The embodiments of the present invention also provide another server platform. Figure 3 For the structure diagram of another server platform provided by the embodiments of the present invention, as Figure 3 shown, this server platform may include the following structure: a device end 10, a power supply unit 20, and a power supply chip 30.

[0048] Specifically, the device end 10 may include: a hardware subsystem 11, a computing acceleration and expansion subsystem 12, a hard disk backplane 13 (Back Plane, BP), a fan 14 (FAN), and a server core component 15.

[0049] Among them, the hardware subsystem 11 is sequentially connected to the power supply chip 30 and the CRPS power supply through a buck converter 40 (Buck); the computing acceleration and expansion subsystem 12 is sequentially connected to the power supply chip 30 and the CRPS power supply; the hard disk backplane 13 is sequentially connected to the power supply chip 30 and the CRPS power supply; the fan 14 is sequentially connected to the power supply chip 30 and the CRPS power supply; the server core component 15 is sequentially connected to the power supply chip 30 and the CRPS power supply.

[0050] Specifically, the hardware subsystem 11 is used to support the computing function, storage function, network function, and management function of the server; the hard disk backplane 13 is used to connect the hard disk storage device; the fan 14 is used for heat dissipation; the server core component 15 is used to provide the control ability, computing ability, and storage ability for the server.

[0051] Embodiment 3

[0052] The embodiment of the present invention also provides another server platform. Figure 4 It is a structural diagram of another server platform provided by the embodiment of the present invention. As Figure 4 shown, the server platform may include the following structure: a device end 10, a power supply unit 20, and a power supply chip 30. There are two power supply units 20.

[0053] Among them, the device end 10 may include: a hardware subsystem 11, a computing acceleration and expansion subsystem 12, a hard disk backplane 13, a fan 14, and a server core component 15.

[0054] Among them, the hardware subsystem 11 includes: a baseboard management controller 111 (Baseboard Management Controller, BMC), a complex programmable logic device 112 (Complex Programmable Logic Device, CPLD), a logic integrated circuit 113 (Logic Integrated Circuit, LOGIC IC), a serial advanced technology attachment 114 (Serial Advanced Technology Attachment, SATA), a smart network card 115 (Smart Network Interface Card, Smart NIC), an OCP (Open Compute Project, open computing project) network card, a universal serial bus 117 (Universal Serial Bus, USB), and a clock buffer 118 (Clock Buffer, CLK).

[0055] Specifically, the baseboard management controller 111 is used for remote management and monitoring of the server; the complex programmable logic device 112 is used to implement logic control functions; the logic integrated circuit 113 is used to process digital logic signals; the serial advanced technology attachment 114 is used to connect storage devices; the intelligent network card 115 is used for network packet processing, acceleration, and offloading; the OCP network card 116 is used for server and data center design; the universal serial bus 117 and the clock extension chip 118 are used to connect external devices.

[0056] It should be noted that the maximum current supported by the current mass production of the power chip 30 is approximately 50A. Therefore, the number of power chips 30 is specifically considered based on current calculation and timing issues. For the part with large current, multiple power chips 30 can be connected in series to support a larger current. Among them, the heat generation problem caused by the large current also needs to be considered to specifically determine the number of power chips 30 used.

[0057] Among them, the hardware subsystem 11 is controlled by a power chip 30.

[0058] Among them, this platform can support two intelligent network cards 115 and two OCP network cards 116. Currently, the power consumption of the used OCP network card 116 is relatively small, not exceeding 40W at most, and the intelligent network card 115 is about 100W. The power consumption of CPLD, BMC, CLK, USB, SATA, and some logic devices is relatively small. These devices all need standby power support, and the total power consumption does not exceed 500W. With one power chip 30, after connecting to the AC power supply, the power chip 30 corresponding to this part of the device is turned on, and the device 10 has a supply power. In this way, a power chip 30 is added between the CRPS power supply and the device 10 to isolate faults. That is, if a fault occurs in the power chip 30 or the device at the back end, it will not cause voltage fluctuations in the main power supply of the entire CRPS power supply, nor will it affect other devices.

[0059] Among them, the computing acceleration and expansion subsystem 12 includes: a graphics processing unit 121 (Graphics Processing Unit, GPU) and a PCIE adapter card 122.

[0060] Specifically, the graphics processing unit 121 is used for high-performance computing and graphics processing; the PCIE adapter card 122 is used for expanding PCIE slots and supporting the installation of the graphics processing unit 121.

[0061] Among them, the computing acceleration and expansion subsystem 12 is controlled by a power chip 30, and the number of power chips 30 is determined based on the power consumption of the graphics processing unit 121.

[0062] Among them, for applications with a maximum of 4 GPUs in this platform, each GPU uses a separate power chip 30 to control the power supply. This not only achieves fault isolation, that is, a problem with one GPU power supply will not affect the voltage of the entire system, and such a solution is safe and reliable, but also enables staggered power-on to avoid inrush current caused by all devices powering on simultaneously at startup. Currently, GPU servers can also be configured in this way, that is, the power supply of each GPU uses a power chip 30 to isolate it from the main power and the power supplies of other GPUs.

[0063] Among them, the hard disk backplane 13 is controlled by a power chip 30. While the timing is controlled, safe and reliable fault isolation is also achieved.

[0064] Among them, the fan 14 is controlled by a power chip 30, and the number of power chips 30 is determined based on the power consumption of the fan 14.

[0065] Among them, since cards with relatively high power consumption such as the OCP network card 116 and the intelligent network card 115 work in the standby state, the heat of the server in the standby state is relatively high, and the fan 14 also needs to work in the standby state. And the server is required to support a maximum of 4 GPUs. Coupled with the heat generated by the CPU and memory, the heat generation is relatively large in the startup state, and the power consumption of the entire machine's fan 14 will also be relatively large. Therefore, a high-power fan 14 is selected for the fan 14, with a maximum of 130W for each fan 14, and the entire machine has 6 fans 14, approximately 780W in total, requiring two power chips 30. After connecting to the AC power supply, the enables of these two power chips 30 are turned on, and there is power supply at the fan 14 end, and the entire machine can dissipate heat.

[0066] Among them, the server core components 15 include: a voltage regulator 151 (Voltage Regulator, VR), a central processing unit 152 (Central Processing Unit, CPU), and a fifth-generation double data rate memory 153 (Double DataRate 5, DDR5).

[0067] Among them, the number of server core components 15 is two.

[0068] Specifically, the central processing unit 152, the voltage regulator 151, the power chip 30, and the CRPS power supply are connected in sequence; the fifth-generation double data rate memory 153 is connected to the power chip 30 and the CRPS power supply in sequence.

[0069] Among them, both the central processing unit 152 and the fifth-generation double data rate memory 153 are controlled and isolated from the power supply part through the power chip 30.

[0070] Among them, the number of fifth-generation double data rate memories 153 is 16, and the number of power chips 30 is two.

[0071] Among them, the maximum power consumption of the central processing unit 152 is 350W, and the power consumption of the 16 fifth-generation double data rate memories 153 is approximately 300W. Therefore, each central processing unit 152 and its corresponding fifth-generation double data rate memory 153 share two power supply chips 30.

[0072] Among them, each central processing unit 152 and 16 fifth-generation double data rate memories 153 share two power supply chips. The dual-processor server includes two central processing units and 32 fifth-generation double data rate memories 153.

[0073] Finally, it should be noted that the above-described embodiments are only specific embodiments of the present invention, used to illustrate the technical solutions of the present invention, rather than limiting them. The protection scope of the present invention is not limited thereto. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: any person skilled in the art within the technical scope disclosed by the present invention can still modify the technical solutions recorded in the foregoing embodiments or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be covered by the protection scope of the present invention.
