[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0044] Generally, after a physical disk adapter hotspot occurs, the system administrator often needs to arrange a system downtime maintenance period, adjust the current physical disk adapter configuration of the virtual server after the system is shut down, and then restart the system, but this method will affect the operation of application business. Therefore, the present application discloses a Power server disk adapter hotspot elimination method, which can avoid shutting down the system of the virtual server first and then adjusting the physical disk adapter configuration of the server partition, reduce the impact of adjusting the current physical disk adapter configuration of the virtual server on user application business, and thus improve the use efficiency of the server device and the operation efficiency of the system.

[0045] Referring to Figure 1 The present application discloses a Power server disk adapter hotspot elimination method, which comprises the following steps:

[0046] In step S11, the use state of the current physical disk adapter in the initial physical server is listened to, and it is determined whether the use state of the current physical disk adapter meets a preset disk adapter hotspot condition.

[0047] In the present embodiment, since the server often has multiple physical disk adapters installed, and the multiple physical disk adapters are allocated to multiple virtual servers for use through virtualization technology, when multiple virtual servers with large business loads share the use of one physical disk adapter, the above-mentioned physical disk adapter will be busy, and thus a physical disk adapter hotspot problem may occur. Therefore, the present application listens to the use state of the current physical disk adapter in the initial physical server, and determines whether the use state of the current physical disk adapter meets a preset disk adapter hotspot condition. When the use state of the disk adapter meets the preset disk adapter hotspot condition, step S12 is performed.

[0048] If the preset disk adapter hotspot condition is met, the target virtual server using the current physical disk adapter is migrated from the initial physical server to a transit physical server by using a dynamic partition migration technology, so that the target virtual server stops using the current physical disk adapter.

[0049] In the embodiment, if the use state of the current physical disk adapter meets the preset disk adapter hotspot condition, the target virtual server using the current physical disk adapter is migrated from the initial physical server to a transit physical server by using a dynamic partition migration technology, so that the target virtual server stops using the current physical disk adapter. It can be understood that in the process of migrating the target virtual server using the current physical disk adapter from the initial physical server to the transit physical server by using the dynamic partition migration technology, the target virtual server uses the physical disk adapter in the transit physical server, thereby avoiding the problem of data loss that may be caused by the target virtual server stopping using the physical disk adapter in the initial physical server.

[0050] In the process of migrating the target virtual server using the current physical disk adapter from the initial physical server to the transit physical server by using the dynamic partition migration technology, the target virtual server uses the physical disk adapter in the transit physical server, thereby avoiding the problem of data loss that may be caused by the target virtual server stopping using the physical disk adapter in the initial physical server.

[0051] In this embodiment, the target physical disk adapter is determined from the physical disk adapters of the initial physical server that do not satisfy the preset disk adapter hotspot condition, and the target virtual server is migrated from the relay physical server back to the initial physical server by using the dynamic partition migration technology, the target virtual server is set to stop using the physical disk adapter in the relay physical server, and the target virtual server is set to use the target physical disk adapter. It can be understood that the target physical disk adapter is determined from the physical disk adapters of the initial physical server that do not satisfy the preset disk adapter hotspot condition, and specifically can include: screening all physical disk adapters of the initial physical server that do not satisfy the preset disk adapter hotspot condition; screening several physical disk adapters that satisfy the preset disk adapter idle condition from the all physical disk adapters that do not satisfy the preset disk adapter hotspot condition as the target physical disk adapter. That is, when it is judged that the use state of the current physical disk adapter satisfies the preset disk adapter hotspot condition, the other physical disk adapters in the initial physical server are judged and screened in this application, the physical disk adapters that do not satisfy the preset disk adapter hotspot condition are screened out, and several physical disk adapters that satisfy the preset disk adapter idle condition are screened out from the physical disk adapters that do not satisfy the preset disk adapter hotspot condition as the target physical disk adapter. In this way, it can be avoided that the target physical disk adapter satisfies the preset disk adapter hotspot condition after being used by the target virtual server, so that the disk adapter hotspot elimination operation needs to be performed again, the time cost is reduced, and the operation efficiency of the system is improved.

[0052] In the embodiment, the use state of a current physical disk adapter in an initial physical server is monitored, and it is determined whether the use state of the current physical disk adapter satisfies a preset disk adapter hotspot condition. If the preset disk adapter hotspot condition is satisfied, a target virtual server using the current physical disk adapter is migrated from the initial physical server to a transit physical server by using a dynamic partition migration technology, so that the target virtual server stops using the current physical disk adapter. A target physical disk adapter is determined from physical disk adapters in the initial physical server that do not satisfy the preset disk adapter hotspot condition, and the target virtual server is migrated from the transit physical server back to the initial physical server by using the dynamic partition migration technology, and the target virtual server is set to use the target physical disk adapter. In this way, the physical disk adapter configuration of the virtual server can be adjusted without shutting down the system, the impact of adjusting the current physical disk adapter configuration of the virtual server on user application services is reduced, and the labor cost and technical cost are reduced, thereby improving the use efficiency of the server device and the operation efficiency of the system.

[0053] Referring to Figure 2 As shown in the figure, the embodiment of the application discloses a specific Power server disk adapter hotspot elimination method, which comprises:

[0054] In step S21, the use state of a current physical disk adapter in an initial physical server is monitored, and it is determined whether the use state of the current physical disk adapter satisfies a preset disk adapter hotspot condition.

[0055] In step S22, if the preset disk adapter hotspot condition is satisfied, a preset partition adjustment scheme is obtained, and a transit physical server is determined based on the preset partition adjustment scheme.

[0056] In the embodiment, if the use state of the current physical disk adapter satisfies the preset disk adapter hotspot condition, a preset partition adjustment scheme is obtained, and then the transit physical server is determined based on the obtained preset partition adjustment scheme. It can be understood that the determination of the transit physical server based on the preset partition adjustment scheme can specifically comprise: determining a plurality of available physical servers based on the preset partition adjustment scheme; screening a target physical server from the plurality of available physical servers, and determining the target physical server as the transit physical server. That is, a plurality of available physical servers are determined from other physical servers of the system based on the preset partition adjustment scheme, and a target physical server screened from the plurality of available physical servers is determined as the transit physical server, wherein the preset partition adjustment scheme is a planning scheme for adjusting the virtual server partition on the physical server.

[0057] Step S23, migrating the target virtual server using the current physical disk adapter from the initial physical server to a transit physical server according to the preset partition adjustment scheme by using a dynamic partition migration technology.

[0058] It is to be noted that before the step of migrating the target virtual server using the current physical disk adapter from the initial physical server to a transit physical server according to the preset partition adjustment scheme by using a dynamic partition migration technology, the method can further include: obtaining preset migration policy information in the preset partition adjustment scheme; and determining whether to perform the step of migrating the target virtual server using the current physical disk adapter from the initial physical server to a transit physical server according to the preset partition adjustment scheme by using a dynamic partition migration technology according to the preset migration policy information. That is, whether to perform the step S23 is determined according to the preset migration policy information in the obtained preset partition adjustment scheme. For example, if the migration order of the target virtual server in this migration is 3, and the current migration is only up to the second order, the step S23 is not performed on the target virtual server. It can be understood that the preset migration policy information can be set by a user according to the user's own needs, so that the migration of the server can be performed under the condition of meeting the user's needs.

[0059] It can be understood that before the step of obtaining the preset migration policy information in the preset partition adjustment scheme, the method can further include: determining whether a preset migration permission condition is met; and triggering the step of obtaining the preset migration policy information in the preset partition adjustment scheme if the preset migration permission condition is met. For example, if the operation of migrating the virtual server to the transit server is being performed, it is determined that the preset migration permission condition is not met, and the step of obtaining the preset migration policy information in the preset partition adjustment scheme is triggered after the current migration operation is completed. In this way, the partition configuration adjustment plan of all virtual server partitions on the whole physical server can be obtained, the use state of each physical disk adapter in the whole server is monitored, it is identified whether there is a physical disk adapter hotspot problem, the virtual server is migrated to the transit physical server according to the preset partition adjustment scheme, and the migration period and the migration order of the virtual server migration are determined, so that the dynamic partition migration of the server can be performed according to the configurable migration policy.

[0060] It is to be noted that the current physical disk adapter configuration information, the physical server information, and the basic information of the virtual server can be recorded by using a traditional relational database. For example, three tables are designed as follows, wherein Table 1 is a physical server information table, Table 2 is a virtual server information table, and Table 3 is a physical disk adapter configuration information table.

[0061] Table 1

[0062] Data Name Data Type Data Length Required / Optional Data Description ms_serial_number varchar 60 Server serial number, primary key ms_name varchar 60 Can be null Server name ms_type_model varchar 20 Server model firmware_version varchar 60 Can be null Firmware version create_time datetime 0 Creation time update_time datetime 0 Synchronization update time

[0063] Table 2

[0064] Data Name Data Type Data Length Required / Optional Data Description partition_id int Partition information table primary key default_profile_id int Can be null Default profile id curr_profile_id int Can be null Currently used profile id ms_serial_number varchar 60 Physical machine serial number foreign key lpar_id int Partition id lpar_name varchar 60 Can be null Partition name dlpar_ready tinyint 1 Whether the dlpar is ready rmc_ip_addr varchar 15 RMC IP address is_msp int Whether it is an msp mgm_ip_addrs varchar 255 Can be null Operating system management ip create_time datetime 0 Creation time update_time datetime 0 Can be null Update time Description varchar 255 Can be null Description

[0065] Table 3

[0066] Data Name Data Type Data Length Required / Optional Data Description profile_id int Profile table foreign key slot_id int Adapter slot id slot_type varchar 60 Adapter slot type match_slot_id int Can be null Matching adapter slot id match_partition_id int Can be null Matching virtual server id vlan_id int Can be null VLAN configuration description varchar 255 Can be null Remark

[0067] According to the above three tables, the migration strategy configuration for the migration of the virtual server is recorded, and the migration information of the virtual server is recorded.

[0068] In step S24, a target physical disk adapter is determined from the physical disk adapters of the initial physical server that do not satisfy the preset disk adapter hotspot condition, and the target virtual server is migrated from the transit physical server back to the initial physical server by using the dynamic partition migration technology, and the target virtual server is set to use the target physical disk adapter.

[0069] In this embodiment, it is pointed out that after the target virtual server is migrated from the transit physical server back to the initial physical server by using the dynamic partition migration technology, the method specifically further includes: obtaining a preset configuration script, so as to complete server configuration verification according to the preset configuration script.

[0070] In this embodiment, the use state of the current physical disk adapter in the initial physical server is monitored, and it is determined whether the use state of the current physical disk adapter satisfies a preset disk adapter hotspot condition; if the preset disk adapter hotspot condition is satisfied, a preset partition adjustment scheme is obtained and a transit physical server is determined based on the preset partition adjustment scheme; a target virtual server using the current physical disk adapter is migrated from the initial physical server to the transit physical server by using a dynamic partition migration technology and according to the preset partition adjustment scheme; a target physical disk adapter is determined from the physical disk adapters of the initial physical server that do not satisfy the preset disk adapter hotspot condition, and the target virtual server is migrated from the transit physical server back to the initial physical server by using the dynamic partition migration technology, and the target virtual server is set to use the target physical disk adapter. Through the above scheme, the present application can perform partition configuration adjustment planning on all virtual servers on the whole physical server according to a preset partition adjustment scheme, which facilitates the operation of the user, saves the time cost and the technical cost, and improves the operation efficiency of the system.

[0071] The specific embodiments of the Power server disk adapter hotspot elimination method disclosed in the present application are described below in comparison with prior art solutions.

[0072] As shown in Figure 3 , Figure 3 is a prior art method of modifying virtual server configuration to eliminate physical disk adapter hotspot. Since virtual servers VM1 and VM2 use physical disk adapter C1 and virtual server VM3 uses physical disk adapter C2, C1 is heavily loaded and C2 is lightly loaded, which results in C1 being busy and C2 being idle, and there is a physical disk adapter hotspot in the E980 server. At this time, virtual server VM2 is closed, and the configuration of virtual server VM2 is modified so that virtual server VM2 uses physical disk adapter C2. However, this method requires that virtual server VM2 be closed before adjusting the current physical disk adapter configuration of virtual server VM2, and all application services running on virtual server VM2 are stopped, and then virtual server VM2 is restarted, which affects the running of application services and causes inconvenience to users, and reduces the efficiency of the system.

[0073] As shown in Figure 4 , Figure 4 is a specific Power server disk adapter hotspot elimination method disclosed in the present application. When a physical disk adapter hotspot occurs in the physical disk adapter C1 connected to the target virtual server VM2 in the initial physical server E980, the application services running on the target virtual server VM2 do not need to be stopped, and the LPM (Live Partition Mobility) technology can be used to migrate the target virtual server VM2 to the transit physical server E924, and set the target virtual server VM2 to use the physical disk adapter C3 in the transit physical server E924, then use the LPM technology to migrate the target virtual server VM2 back to the initial physical server E980, set the target virtual server VM2 to stop using the physical disk adapter C3 in the transit physical server E924, and adjust to use the physical disk adapter C2 in the initial physical server E980, thereby eliminating the physical disk adapter hotspot.

[0074] As shown in Figure 5 , the present application discloses a Power server disk adapter hotspot elimination device, comprising:

[0078] In the present application, the use state of the current physical disk adapter in the initial physical server is monitored, and it is determined whether the use state of the current physical disk adapter meets a preset disk adapter hotspot condition. If the preset disk adapter hotspot condition is met, the target virtual server using the current physical disk adapter is migrated from the initial physical server to a transit physical server by using a dynamic partition migration technology, so that the target virtual server stops using the current physical disk adapter.

In this way, the system can be avoided to be shut down before the physical disk adapter configuration of the virtual server is adjusted, the influence of adjusting the current physical disk adapter configuration of the virtual server on user application services is reduced, and the human and technical costs are reduced, thereby improving the use efficiency of the server device and the operation efficiency of the system.
