[0034] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0036] In this embodiment, a server is provided. Figure 1 This is a schematic diagram of the structure of the server according to the embodiment of the present application. Figure 1 ,like Figure 1 As shown, the server includes: a server host, a storage switch, multiple storage components, a control component and a power supply component, and the control component is connected to the power supply component (there are many possibilities for the specific connection method, Figure 1 The different possibilities are shown only with dashed lines. Figure 1 The dotted line in the figure indicates that the connection mode is not specifically limited), the storage switch is connected between the server host and the multiple storage components, the power supply component is respectively connected to the multiple storage components, and the control component is connected to the server host;

[0037] A storage switch is used to use multiple storage components as a storage resource pool to provide storage resources for the server host;

[0038] The control component is used to detect resource adjustment information of the server host during the operation of the server host, wherein the resource adjustment information is used to indicate the adjustment status of the storage resources allocated by the storage switch to the server host; and adjust the power supply status of each storage component by the power supply component to match the resource adjustment information.

[0039] Through the above content, since the server includes a server host and multiple storage components and also includes a storage switch, a control component and a power supply component, the storage switch is connected between the server host and the multiple storage components, and the storage switch can use the multiple storage components as a storage resource pool to provide storage resources for the server host. In addition, the control component is connected to the server host while also connected to the power supply component, and the power supply component is connected to multiple storage components respectively. The control component can detect the adjustment of the storage resources allocated to the server host by the storage switch based on the above connection relationship during the operation of the server host and adjust the power supply status of each storage component by the power supply component to match the storage resources allocated to the server host, so that the power supply status of each storage component in the server can be flexibly adjusted according to the usage changes of the storage resources of the server host. The unused storage components are not powered, and the storage components that need to be used are powered normally, thereby improving the matching between the storage resources currently used by the server host in the server and the storage resources currently available in the server, and improving the utilization rate of the storage resources by the server host. Therefore, the problem of low utilization rate of storage resources in related technologies can be solved, and the effect of improving the utilization rate of storage resources can be achieved.

[0040] Optionally, in the embodiments of the present application, the server host may refer to, but is not limited to, a computer hardware system specifically used for hosting and running server software. The server host usually has high performance, stability and reliability to meet various service requirements, such as website hosting, database management, file storage and sharing, etc. The server host is usually equipped with a high-performance processor to handle a large number of concurrent requests and high-load tasks. The server host requires sufficient memory to support the operation of multiple applications and services to ensure stable operation of the system. The server host usually uses a high-speed solid state drive (SSD) or a high-performance hard disk (HDD, Hybrid Hard Drive) to store data to increase the data reading and writing speed. The server host requires a high-speed and stable network connection to ensure the efficiency and reliability of data transmission. In order to ensure data security and high availability of the system, the server host usually has redundant power supplies, redundant network connections and data backup functions. The server host needs to have a certain degree of scalability so that more hardware resources, such as additional hard disks, memory or processors, can be added when the business grows.

[0041] Optionally, in an embodiment of the present application, a storage switch may be, but is not limited to, a switching device connected between a server host and multiple storage components, and using multiple storage components to form a storage resource pool to provide storage resources for the server host. For example, the storage switch may be a CXL switch, and the CXL switch integrates the storage resources provided by multiple storage components into a storage resource pool through the CXL storage resource pooling technology and provides it to the server host for use. Alternatively, the storage switch may be a SAN (Storage Area Network) switch, and the SAN switch integrates the storage resources provided by multiple storage components into a storage resource pool through the virtualized storage network resource pooling technology and provides it to the server host for use. More specifically, the SAN switch uses storage virtualization technology, such as LUN (Logical Unit Number) mapping, to virtualize the storage space of storage components of, for example, multiple physical storage arrays into a unified storage resource pool. In this resource pool, the storage space can span different physical devices, but to the server host, they appear to be a single storage device.

[0042] Optionally, in the embodiment of the present application, the multiple storage components may be, but are not limited to, multiple storage devices of the same type supporting resource pooling technology, such as multiple DRAMs (Dynamic Random Access Memory), or multiple SRAMs (Static Random Access Memory), or multiple NVDIMMs (Non-Volatile Dual In-line Memory Modules), etc. The multiple storage components may also be, but are not limited to, a combination of multiple different types of storage devices supporting resource pooling technology, such as a combination of multiple DRAMs and multiple SRAMs, etc.

[0043] Optionally, in an embodiment of the present application, a storage component may also include but is not limited to a storage controller and multiple storage units, the storage controller may include but is not limited to MXC, and the storage unit may include but is not limited to DRAM, SRAM, NVDIMM, etc.

[0044] Optionally, in an embodiment of the present application, a storage switch connected between a server host and multiple storage components is used to use multiple storage components as a storage resource pool to provide storage resources for the server host, replacing the solution in which the server host directly connects to a PCIe card that integrates multiple storage components and then obtains the storage resources integrated on the PCIe card. The storage switch can dynamically allocate storage resources to the server host according to the needs of the host business and flexible deployment, and the capacity of storage resources is no longer fixed. On this basis, some storage components are no longer used by the server host. In order to improve resource utilization and avoid resource waste, the present application proposes a solution for using a control component and a power supply component to control the power supply status of multiple storage components.

[0045] Optionally, the control component may be, but is not limited to, a device with a control function, such as various processors, such as a CPU (Central Processing Unit), an MCU (Microcontroller Unit), a BMC (Baseboard Management Controller), a CPLD (Complex Programmable Logic Devic) or an FPGA (Field-Programmable Gate Array). The control component may also be, but is not limited to, a combination of multiple devices with a control function, and the devices in the device combination corresponding to the control component respectively complete different parts of the function implemented by the control component, such as a combination of different processors, specifically a combination of a CPU and a BMC, a combination of a CPU and multiple BMCs, or a combination of a CPU, multiple BMCs and multiple CPLDs. This application does not make specific restrictions on this.

[0046] Optionally, in an embodiment of the present application, the power supply component may be, but is not limited to, a device that can be controlled to supply power to the outside. For example, it may be a combination of a relay and a power supply, or a combination of a transistor and a power supply. Optionally, the power supply component may also be, but is not limited to, a device that converts the received electric energy and outputs it to the outside. It is necessary to supply power to these devices that convert the received electric energy and output it to the outside in the server. These devices that convert the received electric energy and output it to the outside will adjust the output electric energy according to the instructions of the control component to achieve the adjustment of the power supply status of each storage component. Specifically, such a device may be a power management integrated circuit (PMIC, Power Management Integrated Circuit).

[0047] Optionally, in the embodiments of the present application, Figure 2A schematic diagram of a connection method between a control component and a power supply component according to an embodiment of the present application Figure 1 , Figure 3 A schematic diagram of a connection method between a control component and a power supply component according to an embodiment of the present application Figure 2 The connection between the control component and the power supply component can be, but is not limited to, Figure 2 The control component shown is directly connected to the power supply component, or it can be but not limited to the following Figure 3 The control component and the power supply component are indirectly connected through the connection between the control component and the storage switch, the connection between the storage switch and multiple storage components, and the connection between the power supply component and multiple storage components. The connection method between the control component and the power supply component can be flexibly selected according to the needs of the application scenario, but is not limited to. For example, when the interface pins of the storage switch and multiple storage components have power supply control pins or idle pins, an indirect connection method can be selected to reuse the storage switch, the interfaces of multiple storage components, and the connection cables between the storage switch and multiple storage components. For example, when the control component and the power supply component are integrated on a circuit board, a direct connection method between the control component and the power supply component can be adopted to reduce the connection lines across the circuit board.

[0048] Optionally, in the embodiment of the present application, the resource adjustment information includes but is not limited to the resource adjustment requirements sent by the host to the storage switch, and the control component can determine the adjustment operation of the storage switch to allocate storage resources to the server host according to the resource adjustment requirements, and further determine the adjustment of the storage resources allocated by the storage switch to the server host. Optionally, the resource adjustment information can also be obtained by comparing the results of the resource allocation information on the server host periodically collected by the control component.

[0049] Optionally, in an embodiment of the present application, the control component is used to detect resource adjustment information of the server host during the operation of the server host, including but not limited to sending adjustment requirement acquisition information by the control component to the host, and after receiving the adjustment requirement acquisition information, the host will also send the resource adjustment requirement to be sent to the storage switch to the control component, or the control component sends resource allocation acquisition information to the server host, and after receiving the resource allocation acquisition information, the host will return the current resource allocation information of the server host to the control component. The control component stores the resource allocation information sent by the server host last time, and based on the comparison results of the two resource allocation information, it can be determined which storage components' usage status has changed.

[0050] Optionally, in an embodiment of the present application, the control component is also used to adjust the power supply status of each storage component by the power supply component to match the resource adjustment information, including but not limited to the control component outputting the power supply control signal of each storage component that matches the resource adjustment information and transmitting it to the power supply component, or after the control component determines the target storage component whose usage status has changed on the server host, the control component determines the power supply control signal of the target storage component as a power supply control signal having the opposite control effect of the power supply control signal of the target storage component output last and outputs it to the power supply component, for example, if the power supply control signal of the target storage component last time instructs the power supply component to supply power to the target storage component, then the power supply control signal output this time is a control signal instructing the power supply component to stop supplying power to the target storage component.

[0051] It can be seen from the above that after using the control component and the power supply component to control the power supply status of multiple storage components, the storage components that are not allocated to the server host by the storage switch can be stopped from being powered, and the storage components that are newly allocated to the server host by the storage switch can be powered on, thereby ensuring the normal use of storage resources by the server host while avoiding waste of resources.

[0052] As an optional implementation, the control component includes: a first control machine and a second control machine, the first control machine is connected to the second control machine, the first control machine is connected to the server host, and the second control machine is connected to the power supply component; the first control machine is used to detect resource adjustment information based on resource allocation information of the server host, wherein the resource allocation information is used to indicate the storage resources allocated by the storage switch to the server host; convert the resource adjustment information into state change information, wherein the state change information is used to indicate a target storage component among multiple storage components whose usage status on the server host has changed; send the state change information to the second control machine; the second control machine is used to adjust the power supply status of the target storage component by the power supply component according to the state change information.

[0053] Optionally, in an embodiment of the present application, the control component may, but is not limited to, include a first control machine for converting resource adjustment information of a server host into state change information of a target storage component indicating that a usage state transition has occurred, and a second control machine for adjusting the power supply component to the power supply state of the target storage component according to the state change information.

[0054] Optionally, in an embodiment of the present application, the correspondence between the storage resources used by the server host and the storage resources provided by each storage component may be recorded in the first control machine but is not limited to, so that the first control machine can realize the conversion of resource adjustment information into state change information.

[0055] Optionally, in an embodiment of the present application, the first control machine and the second control machine may be, but are not limited to, a device with a control function or a combination of multiple devices with a control function. The devices in the device combination corresponding to the first control machine respectively complete different parts of the functions implemented by the first control machine, and the devices in the device combination corresponding to the second control machine respectively complete different parts of the functions implemented by the second control machine. For example, the first control machine may be a processor, and the second control machine may be a combination of a BMC and two CPLDs.

[0056] Through the above, a two-layer control mechanism is realized through the division of labor and cooperation between the first control machine and the second control machine, in which the first control machine focuses on monitoring and analyzing resource requirements, and the second control machine focuses on the actual execution of resource adjustment. This mechanism enables resource management to quickly respond to host requirements and efficiently perform resource adjustment operations, enhancing the overall coordination and performance of the server.

[0057] As an optional implementation, the first control machine is used to: collect current resource allocation information from the server host; compare the current resource allocation information with the resource allocation information collected last time; if the current resource allocation information is consistent with the resource allocation information collected last time, determine the resource adjustment information as the first adjustment information, wherein the first adjustment information is used to indicate that the storage resources allocated by the storage switch to the server host have not been adjusted; if the current resource allocation information is inconsistent with the resource allocation information collected last time, determine the resource adjustment information as the second adjustment information, wherein the second adjustment information is used to indicate that the storage resources allocated by the storage switch to the server host have been adjusted.

[0058] Optionally, in an embodiment of the present application, collecting current resource allocation information from the server host includes but is not limited to the first control machine requesting the server host to obtain the current resource allocation information of the server host at a fixed frequency, or the first control machine monitoring the communication between the server host and the storage switch, and upon monitoring that a communication between the server host and the storage switch is completed, requesting the server host to obtain the current resource allocation information of the server host.

[0059] Through the above, the first control machine continuously collects resource allocation information from the server host, which reflects the current usage of resources in the storage resource pool. This continuous monitoring mechanism enables the system to track the dynamic changes of resources in real time and provides a basis for dynamic resource adjustment.

[0060] As an optional implementation, the first control machine is used to: when the resource adjustment information is the first adjustment information, convert the first adjustment information into the first change information, wherein the first change information is used to indicate that there is no target storage component among the multiple storage components, and the state change information includes the first change information; when the resource adjustment information is the second adjustment information, extract the target storage component from the current resource allocation information and the resource allocation information collected last time to obtain the second change information, wherein the second change information is used to indicate that the usage status of the target storage component among the multiple storage components on the server host has changed, and the state change information includes the second change information.

[0115] Optionally, a more specific server is also given in the application. Figure 4 This is a schematic diagram of the structure of the server according to the embodiment of the present application. Figure 2 ,like Figure 4 As shown, it is mainly composed of two parts, one is the server host and the corresponding storage configuration device, and the other is the memory box. In the memory box, there are two BaseBoards (respectively recorded as BaseBoard1 and BaseBoard2) for carrying various management units, CPLD logic control units and power supply modules of the memory exchange board and memory expansion board. There are three types of management units, namely, the detachable mCPU (a processor) (i.e. the aforementioned third control machine or the first control machine), the network management unit and the BMC. There is no mCPU on the BaseBoard2 connected to the memory expansion board. The first configuration supported by the memory box is 1 memory exchange board with 1 memory expansion board, and the second is 1 memory exchange board with 2 memory expansion boards. Users can flexibly choose according to business needs when using it.

[0116] The internal modules of the memory exchange board mainly include CXL Switch (i.e. the aforementioned storage switch), and the external interfaces include PCIe interface and memory device interface (i.e. the aforementioned first cable interface). The PCIe resource of the host is connected to the uplink port of SW (i.e. the aforementioned CXL2.0 Switch) through CDFP cable, and the downlink of SW - memory device interface is connected to the memory expansion board through CDFP cable. The memory exchange board can be connected to BaseBoard1 through MCIO (Multimode ConnectorInsertion / Extraction, multimode fiber insertion / extraction) cable. MCIO is mainly used to transmit the monitoring signal of BMC1 (i.e. the aforementioned third device or first controller) to the memory exchange board, I2C communication signal, and CPLD power control signal. The mCPU, BMC1 and network management unit on BaseBoard1 are interconnected in pairs, CPLD1 (i.e. the aforementioned fourth device or first device) is connected to BMC1, and CPLD1 is connected to the power supply module (i.e. the aforementioned second power supply module). Both CPLD1 and the power supply module are connected to the memory exchange board.

[0117] The memory expansion board is mainly equipped with 8 MXCs as memory controllers (i.e. the aforementioned storage controllers). Its upstream interface (i.e. the aforementioned second cable interface) is connected to the memory switch board through a CDFP cable, and the downstream interface is connected to the memory device (i.e. the aforementioned storage unit). The memory device can be a DDR5 DIMM (Dual-Inline-Memory-Modules) strip. Each MXC can support up to 8 DIMMs, and the entire memory expansion board can support up to 64 DIMMs. Table 1 is Figure 1 The memory resource pooling system configuration of the server shown involves 2 memory expansion boards and 4 memory expansion boards, which can expand a total of 256 DIMMs in full configuration. Similarly, the memory expansion board can be connected to BaseBoard2 through an MCIO cable. MCIO is mainly used for BMC2 (the fifth device mentioned above) to monitor the memory expansion board, I2C communication signals, and CPLD power control signals. BMC2 on BaseBoard2 is connected to the network management unit, CPLD2 (the sixth device or the second device mentioned above) is connected to BMC2, and CPLD2 is connected to the power supply module. CPLD2 and the power supply module (the first power supply module mentioned above) are both connected to the memory expansion board.

[0118] Table 1

[0119]

[0120] The mCPU and each BMC can communicate through the network switch and the network management unit on each BaseBoard. In the memory box, BMC1 on BaseBoard1 serves as the master BMC to manage the entire memory box.

[0121] The above introduces the overall architecture of the server. For the configuration in Table 1, Figure 5 This is a flowchart for powering on and off the entire server and reallocating storage resources. The overall power-on sequence is to power on the memory expansion board first, then the memory switch board, and finally the server host. During the operation of the server host, after the host issues an instruction to reallocate memory resources, it is obtained by the mCPU and then passed to the BMC1 and CPLD1 of the memory switch board in sequence. The CPLD2 of the memory expansion board finally realizes the power-on and power-off control of the MXC and DIMM through the CDFP cable.

[0122] More specifically, BMC1 and CPLD1 use the CDFP cable to transmit the power supply control signal to CPLD2, which involves the connection between CPLD1 and the downstream of SW - the memory device interface. Figure 6 1 is a connection diagram of the CPLD1 and the memory device interface according to an embodiment of the present application. Figure 6 As shown, the CDFP connector of the memory exchange board (i.e. the aforementioned memory device interface) needs to lead out a specific pin - the pin corresponding to the Power Enable signal (i.e. the aforementioned power supply control pin), and it is necessary to ensure that the pin sequence of the CDFP connector of the memory exchange board is consistent with the pin sequence of the memory expansion board. The control end of each Power Enable signal (i.e. the PWREN signal, i.e. the aforementioned power supply control signal) is CPLD1, which is connected to the CDFP connector of the memory expansion board through a CDFP cable, and the power supply control of MXC and DIMM is realized through CPLD2. In addition, the connection relationship between the CDFP connector of the memory exchange board and the memory expansion board is not fixed. All the downstream ports of the memory exchange board can be connected to any CDFP port of the CDFP connector of the memory expansion board at will, and the memory device under this port can be used.

[0123] After the power supply control signal is transmitted to CPLD2 through the CDFP cable and the CDFP interface, CPLD2 transmits the enable signal included in the power supply control signal to the corresponding power supply module. Figure 7 is a schematic diagram of a CPLD2 power supply control solution according to an embodiment of the present application, such as Figure 7As shown, the combination of 8 MXCs and DIMMs on the memory expansion board (i.e., the aforementioned storage components) all have independent power supply modules (the power supply module here is the power supply module in BaseBoard2, i.e., the aforementioned first power supply module), the first Power rail (i.e., the aforementioned first power supply channel) of each power supply module - the input control of P12V is enabled by CPLD2, and the last Power rail (i.e., the aforementioned first feedback channel) - the Power good signal of P0V9 (i.e., the aforementioned first feedback signal) is sent to CPLD2 to indicate the power status of the combination of MXC and DIMM. In this way, each combination of MXC and DIMM can be powered on and off independently, meeting the requirements of memory resource reallocation.

[0124] For the logical interaction between BMC1, CPLD1 and CPLD2, the present application also provides an optional implementation method. Specifically, first define 4 bytes in CPLD1 to store the power control signal Power Enable. The 4 bytes total 32 bits (i.e., the aforementioned multiple storage bits) correspond to the 32 ports of the two memory switch boards. BMC1 interacts with CPLD1 through the I2C bus to control the Power Enable Pin (i.e., the aforementioned power control pin) connected to CPLD1. BMC can restart MXC. Each storage bit corresponds to a specific combination of MXC and DIMM on the memory expansion board, which depends on the specific connection relationship of the CDFP cable. More specifically, the control can be implemented in the code using the following expression:

[0125] a) Define four registers:

[0126] wire [7:0] w_bmcTOcpld_SW0_CDFP_PWREN_0;

[0127] wire [7:0] w_bmcTOcpld_SW0_CDFP_PWREN_1;

[0128] wire [7:0] w_bmcTOcpld_SW1_CDFP_PWREN_0;

[0129] wire [7:0] w_bmcTOcpld_SW1_CDFP_PWREN_1;

[0130] b) Assign values ​​through the assign statement:

[0131] For example, assign o_PWREN_CDFP0_N_SW0 = w_bmcTOcpld_SW0_CDFP_PWREN_0 [7];

[0132] Assign the 32 bits in sequence to the corresponding power supply control pins connected to the CPLD1 according to the above format.

[0133] c) Data transmission is achieved between BMC and CPLD through the I2C communication module of CPLD.

[0134] More specifically, the interaction between BMC1 and CPLD1 and CPLD2 involves the interaction when the server is powered on and the interaction during the operation of the server host. When the server is powered on, mCPU and BMC2 control the memory expansion board CPLD2 to directly pull up the P12V_0~P12V_7 level, so that the power supply module supplies power to all MXC and DIMM combinations, and then pull up the MXC ready signal after receiving the corresponding Power good signal for 200ms. During the operation of the server host, when the storage resources allocated by the storage switch to the server host are adjusted, CPLD2 monitors the rising and falling edges of the power supply control signal PWREN input from the CDFP interface in real time. When the falling edge of PWREN input from the CDFP interface is triggered, the corresponding P12V VR (Voltage Regulator) EN is pulled down, so that the power supply module stops supplying power to the corresponding MXC and DIMM. When the rising edge of PWREN input from the CDFP interface is triggered, the corresponding P12V VR EN is pulled high, so that the power supply module starts supplying power to the corresponding MXC and DIMM. The coordination involving BMC1 is:

[0135] Power off: BMC1 sets the corresponding bit position in the register to 0 (which port depends on the specific connection relationship), and then uses CPLD1 to pull down the PWREN of the CDFP interface corresponding to the MXC group that needs to be powered off.

[0136] Power on: BMC1 sets the corresponding bit position in the register to 1 (which port depends on the specific connection relationship), and then uses CPLD1 to pull up the PWREN of the CDFP interface corresponding to the MXC group that needs to be powered on.

[0137] Through the above content, the hardware level adopts the method of supplying power to each MXC and DIMM separately, and the logic control coordinates the power on and off of the memory resource pool through the interactive communication between CPLD and BMC, so as to realize the dynamic allocation of CXL memory resources in the memory resource pool. It can dynamically allocate CXL memory resources to the host according to the needs of the host business and flexible deployment, thereby improving the utilization rate of the entire memory and reducing the cost of memory use.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the principles of the present application shall be included in the protection scope of the present application.
