[0062] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0063] FIG1 is a flowchart of the steps of a resource allocation method provided in an embodiment of the present application, which is applied to a memory management unit in a resource allocation system.

[0064] In an embodiment of the present application, a resource allocation system can be used to implement dynamic allocation of memory resources. The resource allocation system can be mounted on a server cabinet and interconnected by cables for easy deployment. The resource allocation system may include at least two hosts, a switch, a memory management unit, a memory allocation unit, and a memory storage unit. Among them, the switch may be a Compute Express Link (CXL) switch, such as a general-purpose physical network switch. The memory management unit may be a BMC memory management unit, that is, the memory management unit uses a BMC (Baseboard Management Controller) to manage the entire resource allocation system, including memory resource status monitoring, configuration of the memory allocation unit, and the like.

[0065] The memory allocation unit may be a CXL memory allocation unit, which is used to monitor the status of memory and allocate memory. Specifically, it may be composed of modules such as a host memory interface, a memory address router, a memory address allocation unit, a memory device interface, a status acquisition interface, a memory resource interface, a configuration interface, and an initialization unit. The memory storage unit may be a CXL memory storage unit, which may be composed of a memory expansion controller (MXC) and a memory module (such as a CMM (CXL Memory Modual, CXL memory module)). Exemplarily, the memory module may be a memory module in the form of an E1.S, E3.S, or PCIe standard card. The memory storage unit may include at least two memory modules and at least two memory expansion controllers. Each memory expansion controller may be connected to a memory module. The memory expansion controller is used to provide high-bandwidth, low-latency, high-speed interconnection for the processor in the host and the device (memory module) based on the CXL protocol to achieve memory expansion of the memory module.

[0066] In the resource allocation system, at least two hosts are connected to at least two host memory interfaces provided in a memory allocation unit in a one-to-one correspondence via a computing express link bus (CXL). Specifically, each host memory interface in the memory allocation unit is connected to one host. Simultaneously, a memory device interface configured in the memory allocation unit is connected to a memory storage unit in the resource allocation system via the computing express link bus. Specifically, the memory device interface in the memory allocation unit can be connected to a memory expander controller in the memory storage unit in a one-to-one correspondence via the computing express link bus.

[0067] Each host is equipped with local memory, meaning each host has a corresponding storage module. This storage module is used to meet the host's basic system requirements, ensuring normal system operation and fast transfer of hot data. For example, the storage module can be a DIMM (Dual Inline Memory Module), which can be connected to the DIMM based on DDR (Double Data Rate SDRAM).

[0068] At the same time, each host can be connected to a target processor via a two-wire serial bus (I2C), and the target processor can store a host identifier corresponding to the host connected to the target processor. That is to say, for any host in the resource allocation system, the host identifier corresponding to the host and related information will be stored in the target processor connected to the host. In this way, when the host is powered on, the processor in the host will automatically read the host identifier in the target processor and bind to the host. When the host sends a memory acquisition request carrying the host identifier, the memory management unit can determine the host that sent the memory acquisition request, avoiding the loss of the correspondence between the host and the host identifier due to power failure of the host, which affects subsequent resource allocation. Exemplarily, the target processor can be an EEPROM processor. The host identifier can be a hexadecimal number, such as 0x00, 0x01, 0x02, 0x03, etc. It is understandable that the embodiments of the present application are not limited to this.

[0069] As shown in FIG1 , the method may include:

[0070] Step 101: In response to a memory acquisition request forwarded by a switch in a resource allocation system, acquire a memory demand capacity and a memory start address carried in the memory acquisition request; the memory acquisition request is sent to the switch by any target host among at least two hosts included in the resource allocation system.

[0071] In an embodiment of the present application, when the storage module configured on any target host among at least two hosts does not meet the preset storage conditions, a memory acquisition request will be sent to the switch via the network. The memory acquisition request carries the host identifier corresponding to the target host, the memory resource capacity required by the target host, i.e., the memory demand capacity, and the memory start address. The memory start address is determined based on the storage size of the storage module corresponding to the target host. For example, assuming that the storage size of the storage module is 64GB, the address range of the storage module is 0x00000000-0x107fffffff, and the CXL memory start address required by the target host needs to be +1 based on the tail address of the storage module, that is, 0x1080000000. Among them, the preset storage condition can be that the storage module does not have the ability to provide the target host with the memory resources it requires, for example, the remaining free memory of the storage module is less than the memory resource capacity required by the target host, i.e., the memory demand capacity, etc.

[0072] When any target host in the resource allocation system sends a memory acquisition request to a switch, the switch forwards the request to the memory management unit, which is connected to the switch via a network. Upon receiving the request, the memory management unit parses the request and retrieves the host identifier, requested memory capacity, and starting memory address contained in the request.

[0073] Step 102: Based on a memory allocation unit in the resource allocation system, a target memory module matching the required memory capacity is selected from at least two memory modules in the resource allocation system.

[0074] In an embodiment of the present application, a target memory module that matches the required memory capacity is selected from at least two memory modules in the resource allocation system based on a memory allocation unit in the resource allocation system. Exemplarily, the memory allocation unit determines an idle memory module by obtaining the storage status of the at least two memory modules, and selects a target memory module that matches the required memory capacity of the target host from the idle memory modules. The target memory module that matches the required memory capacity of the target host may have a memory capacity that is greater than or equal to the required memory capacity.

[0075] Step 103: Based on the memory address router and the memory start address in the memory allocation unit, perform address translation on the target memory module, and allocate the target memory module after address translation to the target host.

[0076] In an embodiment of the present application, since the memory address corresponding to the target host needs to be a continuous address, it is necessary to use the memory address router in the memory allocation unit to perform address conversion based on the memory address and the initial address of the target memory module, and allocate the target memory module after address conversion to the target host through the host memory interface in the memory allocation unit for use.

[0077] In summary, in an embodiment of the present application, a memory management unit in a resource allocation system responds to a memory acquisition request sent by a target host forwarded by a switch in the resource allocation system, obtains the memory demand capacity and memory starting address carried in the memory acquisition request, selects a target memory module that matches the memory demand capacity from at least two memory modules in the resource allocation system based on the memory allocation unit in the resource allocation system, and performs address conversion on the target memory module based on the memory address router and memory starting address in the memory allocation unit, and allocates the target memory module after address conversion to the target host to achieve dynamic resource allocation to the target host. In this way, through the interaction between the memory management unit and the memory allocation unit in the resource allocation system, it is possible to ensure the rapid allocation of idle memory modules in the system. Moreover, based on the actual memory demand of the target host, a target memory module that matches the memory demand capacity can be determined for the target host, and the target memory module can be allocated to the target host, thereby achieving dynamic allocation of memory resources in the resource allocation system while improving the memory resource utilization rate in the resource allocation system and reducing the cost of using memory resources.

[0078] In some embodiments of the present application, a memory management unit in a resource allocation system is connected to a status acquisition interface in a memory allocation unit based on a universal asynchronous receiver / transmitter (UART). The status acquisition interface is used to monitor the memory allocation unit.

[0079] The embodiment of the present application may include the following steps:

[0080] Step 201: Based on a status acquisition interface, obtain temperature information corresponding to a memory allocation unit.

[0081] In the embodiment of the present application, since the memory allocation unit may experience a temperature increase during operation, in order to ensure the performance of the memory allocation unit, it is necessary to monitor the temperature of the memory allocation unit in real time. The memory management unit can monitor the temperature of the memory unit in real time based on the status acquisition interface in the memory allocation unit and obtain temperature information corresponding to the memory allocation unit.

[0082] In an embodiment of the present application, the memory management unit can monitor the temperature of the memory allocation unit in real time through the status acquisition interface in the memory allocation unit to avoid performance problems of the memory allocation unit.

[0083] In some embodiments of the present application, the resource allocation system may include a logic unit and a target fan. The embodiment of the present application may include the following steps:

[0084] Step 301: When temperature information meets a preset temperature condition, a first target signal is sent to a target fan in the resource allocation system based on a logic unit in the resource allocation system; the first target signal is used to obtain speed information corresponding to the target fan.

[0085] In an embodiment of the present application, when temperature information satisfies a preset temperature condition, the current temperature representing the memory allocation unit may affect the performance of the memory allocation unit. Therefore, the memory allocation unit can be cooled by adjusting the fan speed. The memory management unit can be connected to a logic unit in the resource allocation system via a two-wire serial bus (Inter-Integrated Circuit, I2C). The logic unit can be a complex programmable logic device (CPLD). The memory management unit can send a first target signal to a target fan in the resource allocation system based on the logic unit in the resource allocation system. Exemplarily, the memory management unit can send a fan adjustment command to the logic unit. After receiving the fan adjustment command, the logic unit can send the first target signal to the target fan. The first target signal is used to obtain the current speed information corresponding to the target fan. Exemplarily, the first target signal can be a TACH signal. The TACH signal is an output pulse signal whose frequency is proportional to the fan speed. The higher the fan speed, the higher the frequency of the TACH signal. Therefore, by measuring the frequency of the TACH signal, the current fan speed can be determined and the speed information corresponding to the target fan can be obtained.

[0086] Step 302: Send a second target signal to the target fan based on the rotation speed information and the temperature information; the second target signal is used to adjust the rotation speed of the target fan.

[0087] In an embodiment of the present application, a second target signal is sent to the target fan based on the speed information and the temperature information. The second target signal is used to adjust the speed of the target fan. For example, the second target signal can be a PWM signal. The PWM signal is a pulse signal with a certain frequency. The logic unit can adjust the duty cycle by sending the second target signal to the target fan, and then adjust the fan speed of the target fan to improve the heat dissipation effect of the memory allocation unit. Exemplarily, the speed difference that needs to be adjusted can be determined based on the temperature information corresponding to the memory allocation unit and the target temperature. Based on the speed difference and the speed information, a second target signal is generated. The second target signal will adjust the speed of the target fan by adjusting the duty cycle.

[0088] In the embodiment of the present application, the rotation speed of the target fan can be adjusted through the memory management unit to ensure the performance of the memory allocation unit.

[0089] In some embodiments of the present application, step 102 may include the following steps:

[0090] Step 401: Based on a memory allocation unit in a resource allocation system, obtain memory allocation status corresponding to each memory module in the resource allocation system.

[0091] In an embodiment of the present application, based on the memory allocation unit in the resource allocation system, the memory allocation status corresponding to each memory module in the memory storage unit can be obtained. Among them, the memory allocation status can include allocated and to be allocated, and accordingly, the memory module can be divided into allocated memory modules and to be allocated memory modules. The memory allocation status may include host information (including host identification, etc.), bandwidth information and device interface connection status corresponding to the allocated memory module, as well as the free memory size corresponding to the to-be-allocated memory module. It is understandable that the memory allocation status can obtain different information according to user needs, and the embodiment of the present application does not limit the memory allocation status.

[0092] In some embodiments of the present application, the memory management unit is connected to the memory resource interface in the memory allocation unit based on a high-speed serial computer expansion bus.

[0093] Step 401 may include the following steps:

[0094] Step 4011: Based on the memory resource interface, the memory allocation status corresponding to each memory module is obtained in real time.

[0095] In an embodiment of the present application, the high-speed serial computer expansion bus may be a PCIe Gen1 x2 bus, that is, the memory management unit may be connected to the memory resource interface in the memory allocation unit via a set of PCIe Gen1 x2 buses to obtain real-time memory resource usage (including the memory allocation status corresponding to the memory module). Thus, when the target host sends a memory acquisition request signal, the memory management unit obtains the memory allocation status corresponding to the memory device based on the memory resource interface in the memory allocation unit to allocate idle memory resources to the target host.

[0096] Step 402: Based on the memory allocation status corresponding to each memory module, determine the memory module to be allocated and the free memory size corresponding to the memory module to be allocated.

[0097] In the embodiment of the present application, based on the acquired memory allocation status corresponding to each memory module, the currently idle memory modules to be allocated and the idle memory size corresponding to each memory module to be allocated are determined.

[0098] Step 403: If the free memory size of the first memory module in the memory modules to be allocated is greater than or equal to the required memory capacity, determine the first memory module as the target memory module.

[0099] In an embodiment of the present application, if a first memory module among the memory modules to be allocated has a free memory size greater than or equal to the required memory capacity, indicating that the target memory module can provide a memory size that meets the host's requirements, then the first memory module can be directly determined as the target memory module. It will be appreciated that if there are multiple first memory modules among the memory modules to be allocated, based on the first difference between the actual capacity of each first memory module and the required memory capacity, the first memory module corresponding to the smallest first difference can be determined as the target memory module.

[0100] Step 404: When the memory size of any memory module to be allocated is smaller than the required memory capacity, a designated memory module is determined as a target memory module; the designated memory module includes at least two memory modules to be allocated.

[0101] In an embodiment of the present application, if the memory size of any to-be-allocated memory module is less than the required memory capacity, this indicates that no single to-be-allocated memory module exists that meets the required memory capacity, and a single to-be-allocated memory module cannot provide sufficient memory capacity to the host. Therefore, a combined allocation based on at least two to-be-allocated memory blocks can be performed to meet the required memory capacity of the host. Specifically, at least two to-be-allocated memory modules whose sum of memory sizes is greater than or equal to the required memory capacity can be selected, i.e., designated memory modules, and determined as target memory modules.

[0102] In the embodiments of the present application, by selecting a memory module to be allocated that is greater than or equal to the required memory capacity as the target memory module, a matching memory module can be selected as the target memory module while avoiding resource waste. Furthermore, if the memory size of a single memory module to be allocated is less than the required memory capacity, the target memory module can be determined by combining the memory modules to be allocated, thereby making resource allocation in the resource allocation system more flexible and diversified.

[0103] In some embodiments of the present application, the memory management unit is connected to the configuration interface in the memory allocation unit via a two-wire serial bus (I2C).

[0104] In an embodiment of the present application, the configuration interface in the memory allocation unit is used to control the initialization of the memory allocation unit, the unified addressing of memory addresses, and the routing of memory addresses. The configuration interface can be connected to the initialization unit in the memory allocation unit to control the initialization unit to initialize the memory allocation unit. The configuration interface can also be connected to the memory address allocation unit in the memory allocation unit to control the memory address allocation unit to perform unified addressing of at least two memory modules. The configuration interface can also be connected to the memory address router in the memory allocation unit to control the memory address router to utilize the mutual cooperation of memory address allocation and memory address routing to allocate the specified target memory module to the target host.

[0105] The embodiment of the present application may include the following steps:

[0106] Step 501: uniformly address at least two memory modules based on a configuration interface.

[0107] In an embodiment of the present application, the memory management unit controls the configuration interface via a two-wire serial bus, and further controls the memory address allocation unit in the memory allocation unit via the configuration interface to uniformly address at least two memory modules in the memory storage unit. For example, assuming that the memory storage unit includes two memory modules, both of which are 64GB, the memory address range corresponding to memory module 1 is 0x0-0x107fffffff, and the address range of memory module 2 is 0x1080000000-0x207fffffff.

[0108] In the embodiment of the present application, at least two memory modules are uniformly addressed through a configuration interface, so that the resource allocation system can allocate resources to the at least two memory modules.

[0109] In some embodiments of the present application, step 103 may include the following steps:

[0110] Step 601: Obtain an initial start address, an initial end address, and a target memory size corresponding to a target memory module.

[0111] In an embodiment of the present application, after determining the target memory module, the initial start address, initial end address, and target memory size corresponding to the target memory module are obtained. The initial start address and initial end address corresponding to the target memory module may be the address information corresponding to the target memory module after unified addressing. The target memory size is the actual available memory capacity corresponding to the target memory module.

[0112] Step 602: Determine the target end address based on the target memory size and the memory start address through the memory address router.

[0113] Step 603: Convert the initial start address to a memory start address, and convert the initial end address to a target end address.

[0114] In an embodiment of the present application, the target memory module is addressed by a memory address router. Specifically, the target end address can be determined based on the target memory size and the memory start address. The target end address is the end address corresponding to the target memory module after the address conversion. Exemplarily, the target end memory corresponding to the target memory module can be determined based on the memory start address and the size of the target memory module corresponding to the target memory module. The initial start address corresponding to the target memory module is converted to the memory start address, and the initial end address corresponding to the target memory module is converted to the target end address, that is, the memory address range corresponding to the target memory module after the address conversion is from the memory start address to the target end address.

[0115] In the embodiment of the present application, the address conversion of the target memory module is realized by a memory address router, so that the allocation of memory resources can be realized quickly.

[0116] In some embodiments of the present application, step 103 may include the following steps:

[0117] Step 701: Based on a host identifier, determine a target host memory interface connected to a target host from at least two host memory interfaces in a memory allocation unit.

[0118] In an embodiment of the present application, at least two hosts in the resource allocation system each correspond to a unique host identifier. After the memory allocation unit determines the target memory module to be allocated to the target host, the target memory module needs to be allocated to the corresponding target host based on the at least two host memory interfaces in the memory allocation unit. The memory management unit obtains the host identifier carried in the memory acquisition request received, and the memory allocation unit can determine the target host memory interface connected to the target host from the at least two host memory interfaces based on the host identifier.

[0119] Step 702: When the memory address router completes the address translation for the target memory module, the memory address router sends the memory start address and the target end address to the target host memory interface.

[0120] In an embodiment of the present application, when the memory address router in the memory allocation unit completes the address conversion of the target memory module, it is characterized that the target memory module can be allocated to the corresponding target host. Therefore, the memory address router can send the memory start address and target end address after address conversion to the target host memory interface to realize memory resource allocation to the target host.

[0121] In an embodiment of the present application, the target memory module is addressed by a memory address router, and then the target memory module after address translation is allocated to the target host through the target host memory interface corresponding to the target host, so that the memory address of the target host remains continuous.

[0122] In some embodiments of the present application, the embodiments of the present application may include the following steps:

[0123] Step 801: Based on the configuration interface, control the initialization unit in the memory allocation unit to perform initialization configuration according to the information in the storage processor.

[0124] In an embodiment of the present application, a configuration interface in the memory allocation unit can control an initialization unit in the memory allocation unit to initialize and configure the memory allocation unit. Based on the configuration interface, the initialization unit is controlled to obtain initialization information stored in the storage processor, and initialize and configure the memory allocation unit based on the initialization information. Wherein, the storage processor can be a FLASH processor, and the initialization information can be initialization content pre-stored in the storage processor. Exemplarily, the initialization unit can be connected to the storage processor based on a serial peripheral interface (SPI).

[0125] In some embodiments of the present application, step 801 may include the following steps:

[0126] Step 8011: When the memory allocation unit is powered on, the initialization unit is controlled based on the configuration interface to obtain initialization information from the storage processor.

[0127] In the embodiment of the present application, when the memory allocation unit is powered on, the initialization unit obtains initialization information from the storage processor, wherein the initialization information may include parameter configuration information and interface enabling information corresponding to the memory allocation unit.

[0128] Step 8012: Based on the initialization information, enable the host memory interface and the memory device interface in the memory allocation unit, and set the transmission bandwidth information and the transmission rate information.

[0129] In the embodiment of the present application, based on the initialization information, the host memory interfaces and the memory device interfaces in the memory allocation unit are enabled, and the transmission bandwidth information and the transmission rate information of the memory allocation unit are initialized and set.

[0130] In the embodiment of the present application, the memory management unit controls the initialization unit through the configuration interface of the memory allocation unit to initialize the memory allocation unit, thereby ensuring the performance of the memory allocation unit.

[0131] For example, Figure 2 shows a schematic diagram of the architecture of a resource allocation system. As shown in Figure 2, the resource allocation system includes four hosts, a switch, a memory management unit, a memory allocation unit, and a memory storage unit. The four hosts are connected to four host memory interfaces in a one-to-one correspondence using CXL. Each host is connected to a storage module and a target processor. The host and storage modules are connected using DDR, and the host and target processor are connected using I2C. Each host is connected to the switch via a network and sends a memory acquisition request to the switch via the network. The switch then sends the memory acquisition request to the memory management unit via the network. The memory management unit can be connected to the status acquisition interface via UART, to the memory resource interface via a PCIe Gen1 x2 bus, and to the configuration interface and logic unit via I2C. In response to the memory acquisition request, the memory management unit obtains the memory allocation status corresponding to the memory module via the memory resource interface. The memory management unit also obtains temperature information corresponding to the memory allocation unit via the status acquisition interface and can control the speed of the target fan via the logic unit to adjust the temperature of the memory allocation unit. The memory management unit can control the initialization unit based on the configuration interface to initialize and configure the memory allocation unit based on the initialization information stored in the storage processor; can control the memory address allocation unit based on the configuration interface to uniformly address the memory addresses of the four memory modules; and can also control the memory address router based on the configuration interface to convert the address of the target memory module. The four memory device interfaces in the memory allocation unit are connected to the memory expansion controllers in the memory storage unit based on CXL, and each memory expansion controller is connected to a memory module. The memory address router connects to the host memory interface upward and receives memory address information from the memory address allocation unit downward. Therefore, the memory address allocation and memory address routing can be used to coordinate and allocate a specified memory module to a specified host.

[0132] Furthermore, FIG3 shows a schematic diagram of the architecture of a server cabinet. As shown in FIG3, the cabinet includes a switch, a memory allocation unit, a memory management unit, and a memory storage unit. The switch is connected to the host via a network bus, the switch is connected to the memory allocation unit and the memory management unit via a network bus, the host is connected to the memory allocation unit and the memory management unit via a computing express link (CXL) bus, and the memory allocation unit and the memory management unit are connected to the memory storage unit via a computing express link (CXL) bus.

[0133] Exemplarily, FIG4 shows a flowchart of the specific steps of a resource allocation method. As shown in FIG4 , the memory management unit controls the memory allocation unit to complete the initialization configuration, and uniformly addresses at least two memory modules based on the memory address allocation unit. After each host in the resource allocation system is powered on, it obtains the host identifier from the corresponding target processor and binds it to its own host. If the storage module of any target host does not meet the preset storage conditions, a memory acquisition request is sent to the switch. The switch forwards the memory acquisition request to the memory management unit, and the memory management unit obtains the memory allocation status corresponding to the memory module, and performs address conversion on the determined target memory module, and then sends the target memory module after address conversion to the target host to realize dynamic allocation of memory resources.

Furthermore, based on the actual memory demand of the target host, a target memory module that matches the memory required capacity can be determined for the target host, and the target memory module can be allocated to the target host, thereby achieving dynamic allocation of memory resources in the resource allocation system, improving the memory resource utilization rate in the resource allocation system, and reducing the cost of using memory resources.
