[0040] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0041] In order to automatically configure the power supply port mapping relationship between the host and the storage device, reduce configuration errors, and thus avoid affecting the normal operation of other hosts, an embodiment of the present application provides a data processing method.

[0042] like Figure 1 As shown, the method includes:

[0043] like Figure 2As shown, the method is applied to a resource manager (RM) in a system, which includes multiple hosts, multiple storage devices (such as JBOD (Just a Bunch Of Disks), NAS (Network Attached Storage), SAN (Storage Area Network) and other storage devices) and a power management unit (PMDU). The power management unit is electrically connected to the power supply unit (PSU) in each host and each storage device through different power supply ports. The resource manager is communicated with the management control unit (BMC) in each host and each storage device through a network card (NIC), and is communicated with the network management port (MGMT) in the power management unit. The storage device is electrically connected to the host's bus adapter (HBA) through at least one expander port (expander). The resource manager is an electronic device responsible for resource management in the system.

[0044] Step 101: Acquire first identification information maintained by the host manager from at least one host based on a manager port of at least one host.

[0045] The resource manager stores the manager port of each host, and accesses the manager port of the host through the network card, thereby obtaining the first identification information maintained by the host manager in the host.

[0046] The first identification information includes all expander ports connected to the host.

[0047] Step 102: Acquire second identification information maintained by the storage device manager from at least one storage device based on the manager port of the at least one storage device.

[0048] The resource manager also stores the manager port of each storage device, and similarly accesses the manager port of the storage device through the network card, thereby acquiring the second identification information maintained by the storage device manager in the storage device.

[0049] The second identification information includes all expander ports of the storage device.

[0050] Step 103: Match the first identification information of the at least one host with the second identification information of the at least one storage device. If the match is successful, it indicates that there is a connection relationship between the host corresponding to the first identification information and the storage device corresponding to the second identification information.

[0051] The acquired first identification information of the host and the second identification information of the storage device are matched, and a successful match indicates that a connection relationship exists between the host corresponding to the first identification information and the storage device corresponding to the second identification information.

[0052] For example, the resource manager obtains the first identification information of host A, the first identification information of host B, the first identification information of host C, and the first identification information of host D, as well as the second identification information of storage device A, the second identification information of storage device B, and the second identification information of storage device C. After matching, the first identification information of host A successfully matches the second identification information of storage device B, and the first identification information of host B successfully matches the second identification information of storage device C. Then, host A and storage device B have a connection relationship, and host B and storage device C have a connection relationship.

[0053] It should be noted that one storage device can be connected to multiple hosts, while one host can only be connected to one storage device. Therefore, one second identification information may successfully match multiple first identification information.

[0054] For example, the resource manager obtains the first identification information of host A, the first identification information of host B, the first identification information of host C, and the first identification information of host D, as well as the second identification information of storage device A, the second identification information of storage device B, and the second identification information of storage device C. After matching, the first identification information of host A successfully matches the second identification information of storage device B, the first identification information of host B successfully matches the second identification information of storage device B, and the first identification information of host C successfully matches the second identification information of storage device C. Then, host A has a connection relationship with storage device B, host B has a connection relationship with storage device B, and host C has a connection relationship with storage device C.

[0055] Step 104: determine power port mapping information based on the connection relationship, wherein the power port mapping information is used to determine a storage device connected to the host when power control is performed on the host, and perform corresponding power control on the storage device connected to the host.

[0056] After determining the connection relationship between the host and the storage device, the power supply port mapping information can be determined.

[0057] For example, it is determined through matching that host A is connected to storage device B, host B is connected to storage device B, and host C is connected to storage device C. Host A is connected to power port A in the power management unit, host B is connected to power port B in the power management unit, host C is connected to power port C in the power management unit, storage device B is connected to power port D in the power management unit, and storage device C is connected to power port E in the power management unit. Then it is determined that the power port mapping information is that power port A is mapped to power port D, power port B is mapped to power port D, and power port C is mapped to power port E.

[0058] In this embodiment, the resource manager can obtain the power supply port of each host and each storage device in the following two ways:

[0059] First, the value of the power supply port of each host and each storage device can be set to be consistent with the value of the manager port. The resource manager can determine the corresponding power supply port through the pre-stored manager ports of each host and each storage device.

[0060] Second, the resource manager accesses the network management port in the power management unit through the network card, thereby obtaining the power supply port connected to the power management port and each host and each storage device.

[0061] In other implementations, any other method capable of acquiring power supply ports of the host and the storage device may be selected.

[0062] In the above scheme, by obtaining the first identification information maintained by the host manager and the second identification information maintained by the storage device manager, and then matching the first identification information with the second identification information, it is determined that the host corresponding to the first identification information that successfully matches and the storage device corresponding to the second identification information have a connection relationship. Then, based on the connection relationship, an accurate power supply port mapping relationship is determined. The power supply port mapping relationship of the host and the storage device is automatically configured, which significantly reduces configuration errors, thereby avoiding affecting the normal operation of other hosts and improving the stability and reliability of the system.

[0063] In an example of the present application, a data processing method is further provided, wherein the obtaining, based on a manager port of at least one host, the first identification information maintained by the host manager from the at least one host comprises:

[0064] Based on the manager port of the host, first identification information of the host is obtained from the bus configuration space of the host through a management control unit in the host, where the first identification information includes at least one unique identifier.

[0065] The resource manager sends a request to the manager port of the host through the network card. After receiving the request, the management control unit in the host obtains the first identification information maintained by the host manager from the bus configuration space (PCIe configuration space, PCIe Configuration Space) in the host, and then sends it to the resource manager.

[0066] The first information identifier includes at least one unique identifier, and the unique identifier is a unique identifier corresponding to the expander port connected to the host.

[0067] Since the first identification information of the host is stored in the bus configuration space, it is necessary to obtain the data stored therein through the bus protocol.

[0068] Therefore, in the above scheme, the resource manager needs to first send a request to the manager port of the host through the network card, and then the management control unit in the host obtains the first identification information maintained by the host manager from the bus configuration space in the host, so that the first identification information of the host can be successfully obtained.

[0069] In an example of the present application, a data processing method is further provided, wherein the acquiring, based on a manager port of at least one storage device, second identification information maintained by the storage device manager from the at least one storage device comprises:

[0070] Based on the manager port of the storage device, second identification information of the storage device is obtained from the storage device through a management control unit in the storage device, where the second identification information includes at least one unique identifier.

[0071] The resource manager sends a request to the manager port of the storage device through the storage device. After receiving the request, the management control unit in the storage device obtains the second identification information maintained by the storage device manager from the storage device and then sends it to the resource manager.

[0072] Since the storage device itself has a storage function, the management control unit in the storage device can directly obtain the second identification information from the storage space of the storage device and then send it to the resource manager.

[0073] In an example of the present application, a data processing method is also provided, wherein the first identification information of the host includes a unique identification of at least one expander port in a storage device connected to the host, and the at least one expander port belongs to the storage device connected to the host;

[0074] The second identification information of the storage device includes unique identifications of multiple expander ports in the storage device.

[0075] For example, Figure 3As shown, host A is connected to storage device A, and host B is also connected to storage device A. Storage device A includes expander port A, expander port B, expander port C, expander port D, and expander port E, and the second identification information of storage device A includes the unique identification of expander port A, the unique identification of expander port B, the unique identification of expander port C, the unique identification of expander port D, and the unique identification of expander port E. Host A is connected to expander port A and expander port B in storage device A, and host B is connected to expander port C and expander port D of storage device A. Then the first identification information of host A includes the unique identification of expander port A and the unique identification of expander port B, and expander port A and expander port B both belong to storage device A that is connected to host A. The first identification information of host B includes the unique identification of expander port C and the unique identification of expander port D, and expander port C and expander port D both belong to storage device A that is connected to host B.

[0076] In an example of the present application, a data processing method is further provided, wherein matching the first identification information of the at least one host with the second identification information of the at least one storage device comprises:

[0077] If the second identification information includes a unique identifier that is the same as the at least one unique identifier in the first identification information, it is determined that the second identification information successfully matches the first identification information.

[0078] For example, the second identification information of storage device A includes the unique identification of expander port A, the unique identification of expander port B, the unique identification of expander port C, the unique identification of expander port D, and the unique identification of expander port E. The first identification information of host A includes the unique identification of expander port A and the unique identification of expander port B. The second identification information of storage device A contains all the unique identifications in the first identification information of host A, so it is determined that storage device A and host A are successfully matched and have a connection relationship.

[0079] In the above scheme, since one storage device can be connected to multiple hosts, and one host can only be connected to one storage device, it is only necessary to determine whether the second identification information of the storage device contains all the unique identifications in the first identification information of the host to determine whether the storage device and the host are successfully matched.

[0080] In an example of the present application, a data processing method is also provided, wherein the first identification information of the host is determined based on a unique identification of at least one expander port in the storage device used to connect to the host, which is obtained when the host establishes a connection with the storage device.

[0081] When the host establishes a connection with the storage device, the storage device is connected to the bus adapter in the host through at least one expander port. At this time, the storage device will send the unique identifier of each expander port connected to the host to the host. After the host receives these unique identifiers, it generates first identification information and stores it.

[0082] In the above solution, when the host establishes a connection with the storage device, it obtains the unique identifier of each expander port connected to the storage device and generates first identification information for storage, so that the subsequent resource manager can match the first identification information with the second identification information of the storage device to determine the connection relationship between the host and the storage device.

[0083] In an example of the present application, a data processing method is also provided, the method further comprising:

[0084] A power supply port connecting the power management unit to the host and the storage device is obtained from the power management unit based on a network management port.

[0085] like Figure 2 As shown, the resource manager obtains the power supply port connected to each host and each storage device of the power management unit from the network management port of the power management unit through the network card.

[0086] In an example of the present application, a data processing method is also provided, such as Figure 4 As shown, the method also includes:

[0087] Step 201: Periodically obtain first identification information of the at least one host and second identification information of the at least one storage device.

[0088] The resource manager periodically obtains the first identification information of the host and the second identification information of the storage device through the network card.

[0089] Step 202: Match the first identification information of the at least one host with the second identification information of the at least one storage device. If the match is successful, it indicates that there is a connection relationship between the host corresponding to the first identification information and the storage device corresponding to the second identification information.

[0090] The acquired first identification information of the host and the second identification information of the storage device are matched to determine a connection relationship between the host and the storage device.

[0091] Step 203: Update the power supply port mapping information based on the connection relationship.

[0092] The power supply port mapping information is updated based on the re-determined connection relationship between the host and the storage device.

[0093] After the power port mapping information is determined, the connection relationship between the host and the storage device may change due to function changes or human operations, thereby causing the power port mapping relationship to change. At this time, if power control is still performed based on the previously determined power port mapping information, the wrong storage device will be controlled accordingly, thereby affecting the normal operation of other hosts.

[0094] It should be noted that when the connection relationship between the host and the storage device changes, the first identification information in the host will be modified based on the change.

[0095] Therefore, in the above scheme, by periodically acquiring the first identification information of the host and the second identification information of the storage device, matching the first identification information and the second identification information, re-determining the connection relationship between the host and the storage device, and then updating the power supply port mapping information, the power supply port mapping information can always be kept accurate and effective, further reducing configuration errors, thereby avoiding affecting the normal operation of other hosts, and improving the stability and reliability of the system.

[0096] In order to implement the above data processing method, Figure 5 As shown, an example of the present application provides a data processing device, including:

[0097] The communication module 10 is used to obtain the first identification information maintained by the host manager from the at least one host based on the manager port of the at least one host, and to obtain the second identification information maintained by the storage device manager from the at least one storage device based on the manager port of the at least one storage device;

[0100] The communication module 10 is further used to obtain the first identification information of the host from the bus configuration space of the host through the management control unit in the host based on the manager port of the host, wherein the first identification information includes at least one unique identifier.

[0101] The communication module 10 is further configured to obtain second identification information of the storage device from the storage device through a management control unit in the storage device based on a manager port of the storage device, wherein the second identification information includes at least one unique identifier.

[0102] The communication module 10 is also used for the second identification information of the storage device to include unique identifications of multiple expander ports in the storage device.

[0103] The calculation module 20 is further configured to determine that the second identification information successfully matches the first identification information if the second identification information contains a unique identifier that is the same as the at least one unique identifier in the first identification information.

[0104] The calculation module 20 is further used to determine the first identification information of the host based on a unique identification of at least one expander port in the storage device used for connecting to the host, which is obtained when the host establishes a connection with the storage device.

[0105] The communication module 10 is further configured to obtain, from the power management unit based on a network management port, a power supply port through which the power management unit is connected to the host and the storage device.

[0106] Wherein, the communication module 10 is further used to periodically obtain the first identification information of the at least one host and the second identification information of the at least one storage device;

[0107] The calculation module 20 is further used to match the first identification information of the at least one host with the second identification information of the at least one storage device, and a successful match indicates that the host corresponding to the first identification information and the storage device corresponding to the second identification information are connected;

[0108] The processing module 30 is further configured to update the power supply port mapping information based on the connection relationship.
