Detailed Description
The system mentioned in the embodiment of the present invention may refer to a server system, for example, a plurality of servers are located in the same cabinet, and then all servers in the cabinet constitute one system. Alternatively, there may be multiple cabinets with one or more servers in each cabinet, which together make up a system, and so on. The embodiments of the present invention are not limited in the definition and scope of the system.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship, unless otherwise specified.
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention provides a server control method, and a flow of the method is described as follows.
Step 101: and determining that the loading number of the first server in the system is less than the preset number.
The system may be monitored, for example, in real time, at regular time or triggered time, to determine information such as the operating status of each node (e.g., server) in the system.
And monitoring to find that the loading number of the first server in the system is less than the preset number. The first server may be any working server in the system, and in addition, at the same time, it may be monitored that the number of the loads of the plurality of servers is less than the preset number, and the processing manner of each server is similar, so that the embodiment of the present invention is exemplified by one server (i.e., the first server).
In the embodiment of the present invention, the number of the loaded servers of the first server is less than the preset number, which may include two cases, where in the first case, the number of the loaded servers of the first server is 0, that is, the first server is unloaded, and in the second case, the number of the loaded servers of the first server is greater than 0, but the number of the loaded servers of the first server is less than the preset number.
Then, if the first server is empty, the subsequent steps can be continued to shut down the first server normally. And if the loading number of the first server is greater than 0, before the first server is closed, the load of the first server needs to be transferred to other servers to ensure the normal operation of the service. The load of the first server is transferred to other servers, which may be performed actively by the system or after receiving the request of the first server.
Optionally, in the embodiment of the present invention, the number of the loads of the first server is greater than 0;
after determining that the loaded number of the first server in the system is less than the preset number, the method further comprises the following steps:
notifying the first server to transfer the load of the first server to a second server in the system; and after the second server receives the load of the first server, the load quantity of the second server is less than or equal to the specified maximum load quantity of the second server.
That is, if the number of the first server is greater than 0, it is necessary that a server in the system can accept the load of the first server to shut down the first server. The second server may be, for example, any working server in the system except the first server, and the second server receives the load of the first server on the premise that the total number of the second servers loaded after the second server receives the load of the first server is less than or equal to the maximum number of the second servers (i.e., the specified maximum number of the second servers), and when the number of the second servers loaded is greater than the specified maximum number of the second servers, the operation of the servers may be problematic.
The above is merely an example of load transfer, that is, the load of the first server is transferred to the second server, and in the actual operation process, there may be no server that can accept the load of the first server in the system, and the load of the first server may be transferred to another plurality of servers, respectively, as long as the total load carrying quantity of the servers that accept the load of the first server is less than the maximum load carrying quantity specified for the servers that accept the load of the first server after accepting the load of the first server.
For example, the system has three servers, namely server 1, server 2 and server 3, and the monitoring determines that the number of the loads of server 1 is 3, the number of the loads of server 2 is 5 and the number of the loads of server 3 is 6. The preset number is 4.
It can be known that the number of the loads of the first server is less than the preset number. Then an attempt may be made to transfer the load of the first server. For example, if the maximum specified number of the server 2 is 8 and the maximum specified number of the server 3 is 8, then all of the 3 loads of the first server may be transferred to the server 2, or two of the loads of the first server may be transferred to the server 3 and the remaining one load may be transferred to the server 2.
For another example, the system has three servers, namely server 1, server 2 and server 3, and the monitoring determines that the number of the loads of server 1 is 2, the number of the loads of server 2 is 4 and the number of the loads of server 3 is 6. The preset number is 4.
It can be known that the number of the loads of the first server is less than the preset number. Then an attempt may be made to transfer the load of the first server. For example, if the maximum number of the specified loads of the server 2 is 8 and the maximum number of the specified loads of the server 3 is 8, then the 2 loads of the first server can be all transferred to the server 2, because the number of the specified loads of the server 2 is small, and the load is light. Or, the 2 loads of the first server may be all transferred to the server 3, so that the server 3 runs fully, and the utilization rate of the server 3 is improved. Alternatively, one of the loads of the first server may be transferred to the server 3, and the remaining one of the loads may be transferred to the server 2, so that the servers share the loads, thereby reducing the load on each server to some extent.
The present invention is not limited with respect to the particular manner of transferring the load, and the manner of selecting the server that receives the load when the transfer is performed.
Step 102: and reading the memory data of the first server, and performing distributed storage on the memory data.
In the embodiment of the present invention, the memory data refers to data stored in a memory, and the data read here may be, for example, all data in the memory of the first server.
That is, the memory data of the first server may be read out first, so that the first server may be restored to the state before shutdown by using the memory data when the first server is restarted next time, which is equivalent to realizing field protection.
Optionally, in the embodiment of the present invention, reading the memory data of the first server includes:
and reading the memory data in a DMA mode.
Optionally, in the embodiment of the present invention, when the Memory data is read, a high-speed reading mode, such as an rock (Remote Direct Memory Access over Converged Ethernet) mode, a DMA (Direct Memory Access) mode, or the like, may be adopted to quickly read the Memory data of the first server.
In the embodiment of the present invention, after the memory data of the first server is read, the read memory data may be stored in a distributed manner. For example, if the capacity of the memory data is 10G, the memory data of 10G may be divided into 10 data blocks in a distributed manner, each data block is 1G (although the memory data may also be unevenly distributed, and the specific distribution manner is not limited in the present invention), and then each data block is stored. Compared with the common storage mode, the distributed storage mode is equivalent to the mode that the original serial storage is changed into the parallel storage, and the data storage efficiency is improved.
Optionally, in this embodiment of the present invention, after performing distributed storage on the memory data, the method further includes:
and recording the storage address of the memory data.
That is, after the memory data is stored in a distributed manner, the storage address of the memory data is recorded so that the memory data can be read when necessary.
Step 103: and controlling to close the first server.
After the memory data of the first server is read, the first server can be closed, and the electric energy resource of the system is saved.
Optionally, in this embodiment of the present invention, before controlling to close the first server, the method further includes:
writing the restart information of the first server into the first server; the restart information is used to restore the state of the first server before shutdown.
Before the first server is closed, the current state information of the first server and the like can be written into the first server as restart information, so that the first server can recover the state before closing by using the restart information when restarting next time.
Optionally, in this embodiment of the present invention, after controlling to close the first server, the method further includes:
opening a first server in a closed state;
transmitting the stored memory data of the first server to the first server; the memory data is used for the first server to restore the state before closing.
For example, the management side may send an instruction to the system, and the system determines to start the first server, or the system may have an excessive number of loads, and the existing server in the running state is not enough to bear all the loads, and the system may determine to start the first server.
Optionally, in this embodiment of the present invention, before transmitting the stored memory data of the first server to the first server, the method further includes:
receiving a request message which is sent by a first server and used for requesting memory data.
That is, after the first server is powered on, the boot state information is detected, and a request message can be sent to apply for restoring the memory data.
Optionally, in this embodiment of the present invention, sending the stored memory data of the first server to the first server includes:
and transmitting the memory data to the first server in a DMA mode according to the recorded memory address of the memory data.
The system can transmit the memory data to the first server in a DMA mode according to the previously recorded memory address of the memory data, and the transmission speed is high. Specifically, the first server may access the memory data in a DMA manner to quickly copy the memory data to the first server.
Optionally, in the embodiment of the present invention, when it is determined that the first server is to be started, the system may read each data block stored in the distributed storage manner according to a storage address of the previously stored memory data, and perform splicing to obtain the original memory data, so that when the first server accesses, the memory data may be directly sent to the first server in a DMA manner, and the first server does not need to perform subsequent self-splicing, thereby reducing a burden of the first server.
Because the distributed storage is adopted, the reading speed is high during reading, and similarly, compared with the existing reading mode, the reading mode corresponding to the distributed storage is equivalent to the mode that the existing serial reading is changed into the parallel reading, so that the reading speed is improved, the starting recovery process of the first server is accelerated, the service quality of a system is improved, the waiting time of a user is reduced, and the user experience is improved.
The numbers before each step in the embodiments of the present invention do not represent the actual execution order of each step, and in practical applications, the steps may be executed in any order.
