Description

Technical Field

[0002] With the continuous development of CXL (Compute Express Link, an open interconnect standard protocol) technology, the CXL memory resource pool built based on the CXL bus provides convenience for the server host to flexibly use storage resources. Currently, it is common to provide storage resources for the server host in the form of connecting a PCIe (Peripheral Component Interconnect Express) standard card. A storage component including an MXC (Memory Expander Controller) and DIMM (Dual-Inline-Memory-Modules) is made into a standard card, and the standard card is inserted into the PCIe slot on the server motherboard to achieve connection with the server host. The server host obtains the storage resource through the CXL bus. However, in this form, the PCIe standard card is powered as a whole by the connected server host, and the storage resources provided by the PCIe standard card for the server host are fixed. This inflexible storage resource provisioning scheme results in a low utilization rate of storage resources by the server host. Summary of the Invention

[0034] In the following, embodiments of the present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

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

[0036] In this embodiment, a server is provided. Figure 1 It is a schematic structure of the server according to the embodiment of the present application. Figure 1 , such as Figure 1 shown, the server includes: a server host, a storage switch, a plurality of storage components, a control component, and a power supply component. The control component is connected to the power supply component (specific connection methods have multiple possibilities. Figure 1 Only different possibilities are shown by dashed lines in Figure 1 , and the dashed lines in

[0037] do not specifically limit the connection method). The storage switch is connected between the server host and the plurality of storage components. The power supply component is respectively connected to the plurality of storage components, and the control component is connected to the server host;

[0038] The storage switch is used to provide storage resources for the server host by using the plurality of storage components as a storage resource pool;

[0039] Through the above, since in the server, in addition to including a server host and multiple storage components, a storage switch, a control component, and a power supply component are also included. The storage switch is connected between the server host and the multiple storage components. The storage switch can use the multiple storage components as a storage resource pool to provide storage resources for the server host. Additionally, while the control component is connected to the power supply component, it is also connected to the server host. The power supply component is respectively connected to the multiple storage components. Based on the above connection relationships, the control component can detect the adjustment of the storage resources allocated to the server host by the storage switch during the operation of the server host and adjust the power supply status of the power supply component to each storage component to match the storage resources allocated to the server host, so that in the server, the power supply status of each storage component 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 normally powered, improving the matching between the storage resources currently used by the server host in the server and the storage resources that can be used 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 the related art 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 but is not limited to refer 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 the stable operation of the system. The server host usually uses high-speed solid-state drives (SSDs, Solid State Drives) or high-performance hard drives (HDDs, Hybrid Hard Drives) to store data to improve the data read and write speed. The server host requires a high-speed and stable network connection to ensure the efficiency and reliability of data transmission. 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 drives, memory, or processors, can be added when the business grows.

[0041] Optionally, in the embodiments of the present application, the storage switch may, but is not limited to, be connected between the server host and multiple storage components, and use the 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 for the server host to use. Or, 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 for the server host to use. More specifically, the SAN switch uses storage virtualization technology, such as LUN (Logical Unit Number) mapping, to virtualize the storage spaces of storage components such as multiple physical storage arrays into a unified storage resource pool. In this resource pool, the storage space can span different physical devices, but for the server host, they appear as a single storage device.

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

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

[0044] Optionally, in the embodiments of the present application, a storage switch connected between the server host and multiple storage components is adopted to use the multiple storage components as a storage resource pool to provide storage resources for the server host, instead of the server host directly connecting to a PCIe standard card integrated with multiple storage components to obtain the storage resources integrated on the PCIe standard card. The storage switch can dynamically allocate storage resources to the server host according to the requirements of the host service and flexible allocation, and the capacity of the storage resources is no longer fixed. On this basis, some storage components are no longer used by the server host. To improve resource utilization and avoid waste of resources, the present application proposes a solution to control the power supply status of multiple storage components using a control component and a power supply component.

[0045] Optionally, the control component can be, but is not limited to, a device with control functions. For example, it can be various processors, such as a CPU (Central Processing Unit), and can also be an MCU (Microcontroller Unit), a BMC (Baseboard Management Controller), a CPLD (Complex Programmable Logic Device), or an FPGA (Field-Programmable Gate Array). The control component can also be, but is not limited to, a combination of multiple devices with control functions. The devices within the corresponding device combination of the control component respectively complete different parts of the functions implemented by the control component. For example, it can be 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. The present application does not make specific limitations on this.

[0046] Optionally, in the embodiments of the present application, the power supply component can be, but is not limited to, a device that can be controlled and supply power externally. For example, it can be a combined device of a relay and a power supply, or a combined device of a transistor and a power supply. Optionally, the power supply component can also be, but is not limited to, a device that converts the received electrical energy and outputs it externally. The devices that convert the received electrical energy and output it externally need to be powered in the server, and these devices that convert the received electrical energy and output it externally will adjust the output electrical 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 can be a power management integrated circuit (PMIC, Power Management Integrated Circuit).

[0047] Optionally, in the embodiments of the present application, Figure 2Schematic 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 Schematic 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 a direct connection between the control component and the power supply component as shown in Figure 2 , or can be but is not limited to an indirect connection between the control component and the power supply component 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 as shown in Figure 3 . The connection method between the control component and the power supply component can be flexibly selected according to the requirements of the application scenario. 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 interfaces of the storage switch, multiple storage components, and the connection cables between the storage switch and multiple storage components. For another 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. The control component can determine the adjustment operation of the storage switch for allocating storage resources to the server host according to the resource adjustment requirements, and further determine the adjustment situation of the storage resources allocated by the storage switch to the server host. Optionally, the resource adjustment information can also be but is not limited to obtained by comparing the results of the control component periodically collecting the resource allocation information on the server host.

[0049] Optionally, in the embodiment of the present application, the control component is used to detect the resource adjustment information of the server host during the operation of the server host, including but not limited to the control component sending adjustment requirement acquisition information to the host. After receiving the adjustment requirement acquisition information, the host will also send the resource adjustment requirements to be sent to the storage switch to the control component, or the control component sends resource allocation acquisition information to the server host. 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. According to the comparison result of the two resource allocation information, it can be determined which storage components have changed in their usage status.

[0050] Optionally, in the embodiments of the present application, the control component is further configured to adjust the power supply states of the power supply component to each storage component to match the resource adjustment information, including but not limited to that the control component outputs power supply control signals of each storage component that match the resource adjustment information to the power supply component, or after the control component determines the target storage component whose usage state on the server host has changed, the power supply control signal of the target storage component is determined as a power supply control signal with a control effect opposite to that of the power supply control signal of the target storage component output last time and is output to the power supply component. For example, if the power supply control signal of the target storage component last time indicates that the power supply component supplies power to the target storage component, then the power supply control signal output this time is a control signal indicating that the power supply component stops supplying power to the target storage component.

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

[0052] As an optional implementation manner, the control component includes: a first controller and a second controller. The first controller is connected to the second controller, the first controller is connected to the server host, and the second controller is connected to the power supply component. The first controller is configured to detect resource adjustment information according to the resource allocation information of the server host, where 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, where the state change information is used to indicate the target storage component whose usage state on the server host has changed among multiple storage components; and send the state change information to the second controller. The second controller is configured to adjust the power supply state of the power supply component to the target storage component according to the state change information.

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

[0054] Optionally, in the embodiments 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, but is not limited to being recorded, in the first controller. Therefore, the first controller can implement the conversion from resource adjustment information to state change information.

[0055] Optionally, in the embodiments of the present application, the first control machine and the second control machine may be, but are not limited to, a device with control functions or a combination of multiple devices with control functions. The devices within 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 within 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 content, through the division of labor and cooperation between the first control machine and the second control machine, a two-layer control mechanism is realized. Among them, the first control machine focuses on the monitoring and analysis of resource requirements, and the second control machine focuses on the actual execution of resource adjustment. This mechanism enables resource management to not only quickly respond to the needs of the host but also efficiently execute resource adjustment operations, enhancing the overall coordination and performance of the server.

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

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

[0059] Through the above content, the first control machine continuously collects resource allocation information from the server host, and these information reflect 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, providing a basis for dynamic resource adjustment.

[0060] As an alternative implementation, the first control machine is configured to: when the resource adjustment information is the first adjustment information, convert the first adjustment information into first change information, where the first change information is used to indicate that there is no target storage component among multiple storage components, and the status 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 previously collected resource allocation information to obtain second change information, where the second change information is used to indicate that the usage status of the target storage component among multiple storage components has changed on the server host, and the status change information includes the second change information.

[0061] Optionally, in the embodiments of the present application, extracting the target storage component from the current resource allocation information and the previously collected resource allocation information may be to determine what changes have occurred in the storage resources allocated to the server host based on the current resource allocation information and the previously collected resource allocation information, and then determine which storage components' usage status has changed, or to determine the current usage status of each storage component according to the current resource allocation information and the usage status of each storage component at the previous collection according to the previously collected resource allocation information, and then determine which storage components' usage status has changed.

[0062] Through the above content, the generation and conversion process of the resource adjustment information is refined, the intelligent level of server storage resource management is improved, and the accuracy, efficiency, and flexibility of resource adjustment are ensured.

For example, if the status change information is to stop using storage component A, the first controller can determine that the power supply control signal A for storage component A is a signal indicating that the power supply component stops supplying power to storage component A according to the status change information. The second controller transmits the power supply control signal A to the power supply component, and the power supply component changes the power supply status of storage component A with reference to the power supply control signal A.

This startup instruction or startup electrical signal is used to trigger the startup of the server host. When the control component detects that the server host has been executed with a startup operation, it first controls the power supply component to supply power to multiple storage components, that is, it first controls the power supply component to start providing electrical energy to multiple storage components.

[0112] Optionally, in the embodiments of the present application, the third device, the fourth device, the fifth device, and the sixth device are all a kind of control device, for example, it can be BMC, CPLD, FPGA, etc.

[0113] Optionally, in the embodiments of the present application, the third device and the fifth device can be but are not limited to BMC, and the fourth device and the sixth device can be but are not limited to CPLD, that is, the fourth control machine and the fifth control machine can be but are not limited to a combination of a BMC and a CPLD.

The more specific operation cooperation method among the third control machine, the third device, the fourth device, the sixth device, and multiple first power supply modules is the same as the specific operation cooperation method among the aforementioned first control machine, the first controller, the first device, the second device, and multiple first power supply modules.

[0115] Optionally, a more specific server is also provided in the application. Figure 4 It is a schematic diagram of the structure of the server according to the embodiment of the present application. Figure 2 As Figure 4 shown, it mainly consists 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 2 BaseBoards (motherboards) (denoted as BaseBoard1 and BaseBoard2 respectively) for carrying each management unit, CPLD logic control unit, and power supply module of the memory exchange board and the memory expansion board. There are three types of management units, namely, a detachable mCPU (a type of processor) (i.e., the aforementioned third control machine or the first control machine), a network management unit, and a BMC. There is no mCPU on 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 configuration is 1 memory exchange board with 2 memory expansion boards. Users can flexibly select according to business needs when using.

[0116] The on-board modules of the memory swapping board mainly include a CXL Switch (i.e., the aforementioned storage switch), and the external interfaces are PCIe interfaces and memory device interfaces (i.e., the aforementioned first cable interfaces). The PCIe resources of the host are connected to the upstream port of the SW (i.e., the aforementioned CXL2.0 Switch) through a CDFP cable, and the downstream - memory device interface of the SW is connected to the memory expansion board through a CDFP cable. The memory swapping board and the BaseBoard1 can be connected through an MCIO (Multimode Connector Insertion / Extraction) cable. The MCIO is mainly used to transmit the monitoring signals of the BMC1 (i.e., the aforementioned third device or the first controller) to the memory swapping board, I2C communication signals, and signals for CPLD power control. The mCPU, BMC1, and network management unit on the BaseBoard1 are interconnected with each other. The CPLD1 (i.e., the aforementioned fourth device or the first device) is connected to the BMC1, and the CPLD1 is connected to the power supply module (i.e., the aforementioned second power supply module). Both the CPLD1 and the power supply module are connected to the memory swapping board.

[0117] The memory expansion board mainly houses 8 MXC as memory controllers (i.e., the aforementioned storage controllers). Its upstream interface (i.e., the aforementioned second cable interface) is connected to the memory swapping board through a CDFP cable, and the downstream is connected to the memory device (i.e., the aforementioned storage unit). The memory device can specifically be a DDR5 DIMM (Dual-Inline-Memory-Modules dual in-line memory module) strip. Each MXC can support up to 8 DIMMs at most, and the entire memory expansion board can support up to 64 DIMMs at most. Table 1 is Figure 1 The memory resource pooling system configuration of the server shown. A total of 2 memory expansion boards and 4 memory expansion boards are involved. In a fully configured manner, a total of 256 DIMMs can be expanded. Similarly, the memory expansion board and the BaseBoard2 can be connected through an MCIO cable. The MCIO is mainly used for the monitoring signals of the BMC2 (i.e., the aforementioned fifth device) to the memory expansion board, I2C communication signals, and signals for CPLD power control. The BMC2 on the BaseBoard2 is connected to the network management unit. The CPLD2 (i.e., the aforementioned sixth device or the second device) is connected to the BMC2, and the CPLD2 is connected to the power supply module. Both the CPLD2 and the power supply module (i.e., the aforementioned first power supply module) are connected to the memory expansion board.

[0118] Table 1

[0119]

[0120] Through the network switch and the network management units on each BaseBoard, the mCPU and each BMC can communicate. Inside the memory box, the BMC1 on BaseBoard1 serves as the master BMC to manage the entire memory box.

[0121] The overall architecture of the server has been introduced above. For the configuration in Table 1, Figure 5 is the flowchart for powering on / 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 switching 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 switching board in sequence. Through the CDFP cable, the CPLD2 of the memory expansion board finally realizes the power-off and power-on control of the MXC and DIMM.

[0122] More specifically, the transmission of the power supply control signal from BMC1 and CPLD1 to CPLD2 via the CDFP cable involves the connection between CPLD1 and the SW's downlink - memory device interface. Figure 6 is the connection diagram of CPLD1 and the memory device interface according to the embodiment of the present application. As Figure 6 shown, the CDFP connector of the memory switching 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 switching board is unified 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 via the CDFP cable, and the power supply control of the MXC and DIMM is realized through CPLD2. In addition, the connection relationship between the CDFP connectors of the memory switching board and the memory expansion board is not fixed. All the downlink ports of the memory switching board can be randomly connected to any CDFP port of the CDFP connector of the memory expansion board to use the memory devices under this port.

[0123] After the power supply control signal is transmitted to CPLD2 via the CDFP cable and CDFP interface, CPLD2 will transmit 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 scheme according to the embodiment of the present application. As Figure 7As shown, each combination of 8 MXC and DIMM on the memory expansion board (i.e., the aforementioned storage components) has an independent power supply module (the power supply module here is the power supply module in BaseBoard2, i.e., the aforementioned first power supply module). The input control of the first Power rail (i.e., the aforementioned first power supply channel) - P12V of each power supply module is enabled by CPLD2, and the Power good signal (i.e., the aforementioned first feedback signal) of the last Power rail (i.e., the aforementioned first feedback channel) - P0V9 is sent to CPLD2 to indicate the power supply status of the combination of MXC and DIMM. In this way, the individual power-on and power-off of each combination of MXC and DIMM can be achieved, meeting the requirements of memory resource reallocation.

[0124] For the logical interaction between BMC1, CPLD1, and CPLD2, the present application also provides an alternative implementation. Specifically, first define 4 Bytes (bytes) in CPLD1 to store the power supply control signal Power Enable. A total of 32 bits (bits) in 4 Bytes (i.e., the aforementioned multiple storage bits) correspond to 32 ports of 2 memory exchange boards. Interact between BMC1 and CPLD1 through the I2C bus to control the Power Enable Pin (i.e., the aforementioned power supply control pin) connected to CPLD1. The BMC can restart the MXC. Which specific combination of MXC and DIMM on the memory expansion board each storage bit corresponds to depends on the specific connection relationship of the CDFP cable. More specifically, the control can be implemented with the following expressions in the code:

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

[0133] c) Through the I2C communication module of the CPLD, data transmission is achieved between the BMC and the CPLD.

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

[0135] Power-off: BMC1 sets the corresponding bit of the register to 0 (which specific port depends on the specific connection relationship), and then through CPLD1, pulls low the PWREN of the CDFP interface corresponding to the MXC of the group to be powered off.

[0136] Power-on: BMC1 sets the corresponding bit of the register to 1 (which specific port depends on the specific connection relationship), and then through CPLD1, pulls high the PWREN of the CDFP interface corresponding to the MXC of the group to be powered on.

[0137] Through the above content, the hardware level adopts the method of separately supplying power to each MXC and DIMM, and the logical control coordinates the power on and off of the memory resource pool through the interaction and communication between the CPLD and BMC, realizing the dynamic allocation of CXL memory resources in the memory resource pool, and being able to dynamically allocate CXL memory resources to the host according to the needs of the host service and flexible deployment, thereby improving the utilization rate of the entire memory and reducing the memory usage cost.

[0138] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the principle of the present application shall be included within the protection scope of the present application.
