Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a storage testing method provided in an embodiment of the present application, it should be understood that the method may be performed by a storage testing apparatus shown in fig. 4, where the apparatus corresponds to a server shown in fig. 5, and the server may be various devices capable of performing the method, for example, a computer or a cloud server, and the embodiment of the present application is not limited thereto, and specifically includes the following steps:
in step S101, the server collects storage pressures caused by multiple virtual machines for performing storage performance test.
Optionally, the server is a storage server.
Alternatively, the storage performance refers to the number of times of read/write (I/O) operations per second, throughput, latency, and the like.
Alternatively, the storage pressure may also be referred to as disk saturation.
Optionally, the disk saturation includes a first pressure value for characterizing utilization of the disk, a second pressure value for characterizing CPU idle duty cycle, and a third pressure value for characterizing the number of blocked processes.
Optionally, the utilization of the disk is an average utilization of the disk. For example, assuming that the number of disks of the current server is N, the average utilization ratio u= (util_disk_1+ & gt util_disk_n)/N of the disks. N is an integer greater than 1. The util_disk_1 indicates the utilization of the first disk, and the util_disk_n indicates the utilization of the nth disk.
Alternatively, the default value of the average utilization of the disk is 1, and u=u-0.1 each time util_disk_n is reduced by 10%. The smaller the U value, the more idle the disk utilization.
Alternatively, the CPU idle duty cycle may be expressed in% idle.
Alternatively, in general the larger the% idle, the more idle the description, i.e. the current server (storage device) pressure does not peak.
Alternatively, the CPU idle duty cycle default value is 0.7, for example, the id field data in the vmstat open source tool may be employed as the CPU idle duty cycle reference value for system overload.
Alternatively, the CPU idle duty cycle i=id/100, i=i-0.1 whenever id is reduced by 10, then compared to the default value, which represents an excessive load, whereas id is increased by 10, i=i+0.1. A larger than default represents a load alleviation.
Alternatively, the blocking process number default value is 0.5, for example, the b field data in vmstat is used as a reference value for the blocking process number of system overload.
Alternatively, whenever the b-field data is incremented by 1, b= (b+1)/10, then compared to the default value, a smaller than default value represents a load alleviation and a larger than default value represents an io overload.
As one implementation, each virtual machine on the server initiates an IO request to the server when performing storage performance test, so that the server can determine the times of performing read-write (I/O) operations per second, throughput, delay and other conditions of a plurality of virtual machines by counting the IO requests initiated by each virtual machine, thereby determining the storage pressure of the virtual machine on the server.
In a possible embodiment, before step S101, the method further includes: the server creates the plurality of virtual machines and creates cloud hard disks for each virtual machine in the plurality of virtual machines respectively, wherein a testing tool for testing storage performance is installed in each cloud hard disk.
Optionally, when the virtual machine is created, an operation system, a configuration network and the like are automatically installed, and the configured information is stored in a configuration file.
Alternatively, the test tool may be fio, iometer, orion, or the like, and is not particularly limited herein. For example, when the test tool is fio, the test tool is installed in the operating system of the virtual machine, and only needs to be completed in the code by using a yum install (or apt get) mode.
Optionally, the test cases are provided to store performance test use in the embodiment by generating an executable script of an open source test tool.
The technical means of < < EOF > can be adopted to automatically generate the executable script, the execution sentences are sequentially written into the script, test cases to be executed are preset, and the super fusion architecture in the server is informed, so that the complete executable script can be generated in the virtual machine operating system after the virtual machine is built.
It should be noted that, the super fusion architecture (i.e. super fusion infrastructure) refers to that resources and technologies such as computing, network, storage, server virtualization and the like are not only provided in the same set of unit equipment (x 86 server), but also include elements such as cache acceleration, repeated data deletion, online data compression, backup software, snapshot technology and the like, and multiple nodes can be aggregated through the network to realize modularized seamless lateral expansion (scale-out) so as to form a uniform resource pool.
Specifically, as shown in fig. 2, before step S101, the method further includes:
step S201, the number of virtual machines input from the terminal is received.
Optionally, the terminal refers to a terminal device used by a user, for example, a computer or a mobile phone. Here, the present invention is not particularly limited.
Alternatively, the number of virtual machines, i.e., the number of virtual machines that the server needs to create.
Step S202, creating a virtual machine.
Step S203, a virtual hard disk is created and bound to the virtual machine.
Optionally, the virtual hard disk corresponds to the cloud hard disk above. After the virtual machines are created, a cloud hard disk is created for each virtual machine.
Step S204, automatically installing an open source tool.
Alternatively, the open source tool refers to a test tool for testing storage performance. Specifically, reference may be made to the above description, and no further description is given here.
Step S205, automatically generating a use case scenario.
Alternatively, the specific embodiment of step S205 may refer to the above description, and will not be described herein.
In step S102, the server determines whether the storage pressure is greater than a preset threshold.
Alternatively, the preset threshold may also be referred to as a disk saturation threshold, which is used to reflect the overall performance of disk utilization, CPU idle rate, and number of blocked processes.
Optionally, the setting of the preset threshold may be set according to the user's requirement. For example, the preset threshold may be 2.2, i.e., the utilization of the disk+the idle rate of the cpu+the number of blocking processes=2.2.
As one implementation, the server determines whether the storage pressure is greater than a preset threshold by comparing the storage pressure to a preset threshold.
As one embodiment, the server determines a sum of the first pressure value, the second pressure value, and the third pressure value; it is determined whether the sum is greater than a preset threshold.
In the implementation process, the first pressure value, the second pressure value and the third pressure value are combined to be compared with the preset threshold value, so that calculation is performed through multiple dimensions, and therefore the storage performance of the server can be tested more accurately.
Step S103, if the threshold value is larger than the preset threshold value, the server deletes the virtual machine from the plurality of virtual machines.
Optionally, deleting a virtual machine refers to ending the initiated test process of the virtual machine so that the virtual machine no longer places storage pressure on the server. For example, after the test process of the virtual machine is finished, the virtual machine does not initiate an IO request by using the test process.
The test process is used for testing the storage performance of the server, such as initiating IO requests.
As one embodiment, step S103 includes: when the storage pressure is greater than a preset threshold value, the server acquires network address information of the virtual machine from the configuration file; and the server sends a termination test instruction to the virtual machine through the network address information so as to delete the virtual machine executing the termination test instruction from the plurality of virtual machines.
Optionally, the configuration file is stored in a server. The configuration file records configuration information of each virtual machine, such as network address information, identification information and the like.
Optionally, the server obtains network address information of the virtual machine from the configuration file, including: the server randomly acquires network address information of the virtual machine from the configuration file.
Of course, in actual use, the server may first obtain the identifier of the virtual machine to be terminated input by the user, and obtain the network address information of the virtual machine matched with the identifier.
As an implementation manner, the server may predict the number of virtual machines to be terminated according to the difference between the storage pressure and the preset threshold. For example, when the difference is greater than 0 and less than the first sub-threshold, the estimated number is 1, when the difference is greater than or equal to the difference and less than the second sub-threshold, the estimated number is 2, and when the difference is greater than or equal to the second sub-threshold and less than the third sub-threshold, the estimated number is 3.
Alternatively, the setting of the first sub-threshold, the second sub-threshold, and the third sub-threshold may be determined according to the user's needs or according to the specifications of the storage device (or the storage server). Here, the present invention is not particularly limited.
Of course, the number of virtual machines to be terminated may also be estimated according to the multiple of the difference value and the second preset threshold value. For example, when the multiple of the difference value and the second preset threshold value is 1, obtaining the estimated quantity to be 1; when the multiple is 2, the estimated number is 2; when the multiple is 3, the estimated number is 3; when the multiple is n, the estimated number is n. Wherein n is an integer greater than 3.
Alternatively, the setting of the second preset threshold may be determined according to the user's needs or according to the specifications of the storage device (or storage server). Here, the present invention is not particularly limited.
It is to be understood that the above is by way of example only and not by way of limitation.
In the implementation process, the network address information of the virtual machine is obtained from the configuration file, so that a termination test instruction is sent to the virtual machine through the network address information, and the virtual machine executing the termination test instruction is deleted from the plurality of virtual machines, thereby reducing the scale of the whole virtual machine participating in the storage performance test, further reducing the phenomenon of inaccurate performance data caused by abnormal load of the server, and improving the accuracy of the test on the storage performance of the server.
Optionally, before the server obtains the network address information of the virtual machine from the configuration file, the method further includes: the server determines the number of virtual machines to be deleted according to the difference value between the storage pressure and the preset threshold value; the server obtains the network address information of the virtual machine from the configuration file, and the network address information comprises: and the server acquires the virtual machine network address information with the quantity corresponding to the quantity of the virtual machines to be deleted from the configuration file.
Optionally, the number of newly added virtual machines/the number of deleted virtual machines satisfies: vms= (Ti-T)/10%; wherein ti=u+i+b; ti represents storage pressure, U represents disk utilization, I represents CPU idle duty ratio, and B represents the number of blocked processes; t is a preset threshold.
Alternatively, if vms is less than 1, then no virtual machine need be added/deleted. If vms is an integer greater than 1, then a corresponding number of virtual machines are added/deleted.
As another embodiment, step S103 includes: and when the storage pressure is smaller than a preset threshold value, the server acquires the number of virtual machines to be terminated, and the virtual machines corresponding to the number are terminated from the plurality of virtual machines.
Alternatively, the number of virtual machines to be terminated may be input by the user through the terminal device.
Of course, the number of virtual machines to be terminated may also be estimated by the server through the comparison result. Here, the present invention is not particularly limited.
In the implementation process, when the number of the virtual machines to be terminated is larger than the preset threshold value, the virtual machines corresponding to the number are terminated from the plurality of virtual machines, so that the scale of the whole virtual machine participating in the storage performance test can be accurately reduced, the phenomenon of inaccurate performance data caused by abnormal load of the server is further reduced, and the accuracy of testing the storage performance of the server is improved.
And step S104, if the storage performance test is smaller than the preset threshold, the server builds a virtual machine so that the built virtual machine and the plurality of virtual machines can perform the storage performance test.
As one embodiment, step S104 includes: when the storage pressure is smaller than a preset threshold value, after suspending the test process of all the current virtual machines, the server establishes a virtual machine, and updates the configuration information of the established virtual machine into a configuration file; and the server starts the test process of all the current virtual machines to perform the storage performance test.
Optionally, if the storage pressure is smaller than the preset threshold, after suspending the test process of all the current virtual machines, determining the number of virtual machines to be added according to the difference between the storage pressure and the preset threshold; newly creating virtual machines with the number corresponding to the number of the virtual machines to be added, and updating the configuration information of the newly created virtual machines into a configuration file; and starting the test process of all the current virtual machines to perform the storage performance test.
In the implementation process, the test process of all the current virtual machines is paused firstly to avoid the influence of other virtual machines on the test when a new virtual machine is created, the test accuracy is improved, then after the new virtual machine is created, the configuration information of the virtual machine is updated into the configuration file so as to facilitate management of the virtual machine, after the creation is successful, all the current virtual machines are started to perform the storage performance test, so that the scale of the whole virtual machines participating in the storage performance test is increased, the server is pressurized in a continuous superposition mode until the critical value is met, and the peak performance of the server is accurately obtained.
Optionally, the process of creating the virtual machine may be performed by executing steps S201 to S205 to automatically create the virtual machine, so that no human intervention is required, and the test efficiency may be effectively improved.
As another embodiment, step S104 includes: when the storage pressure is smaller than a preset threshold value, receiving an increase request for increasing the virtual machine; suspending the test process of all the current virtual machines; newly creating virtual machines corresponding to the increment quantity carried by the increment request; updating the configuration information of all newly-built virtual machines into a configuration file; and starting the test process of all the current virtual machines to perform the storage performance test.
Alternatively, the add request may be input by the user based on the terminal device.
Optionally, the increase request carries an increased number, i.e. the number of virtual machines that need to be increased.
As an application scenario, when the storage pressure is smaller than a preset threshold, the server may display the comparison result or display the comparison result in a pop-up box form, the user initiates an increase request through the displayed comparison result, and after receiving the increase request, the server pauses the test process of all the current virtual machines; newly creating virtual machines corresponding to the increment quantity carried by the increment request; updating the configuration information of all newly-built virtual machines into a configuration file; and starting the test process of all the current virtual machines to perform the storage performance test.
Of course, in actual use, when the storage pressure is smaller than the preset threshold, the server may directly send a prompt message to the terminal device corresponding to the user to prompt the user to perform an operation. Here, the present invention is not particularly limited.
In the implementation process, receiving an increase request for increasing the virtual machine when the storage pressure is smaller than a preset threshold value; suspending the test process of all the current virtual machines; newly creating virtual machines corresponding to the increment quantity carried by the increment request; updating the configuration information of all newly-built virtual machines into a configuration file; and starting the test process of all the current virtual machines to perform the storage performance test. The scale of the whole virtual machine participating in the storage performance test is accurately increased, and the server is pressurized in a continuous superposition mode until the critical value is met, so that the peak performance of the server is further accurately obtained.
The server in the present application refers to a storage server, i.e., a server having a storage space.
The memory test method of the present application was described above in connection with fig. 1, and the memory test method of the present application will be described in detail below by way of example and not limitation in connection with fig. 3. The method as shown in fig. 3 includes:
step S301, it is determined whether to increase or decrease.
Alternatively, it is determined whether the difference between the storage pressure and the preset threshold is increased or decreased, and the difference between the default storage pressure and the preset threshold may be equal to about 0 at the beginning. When the difference value increases, namely the storage pressure increases, the storage pressure is larger than a preset threshold value; if the storage pressure is reduced, namely, the storage pressure is reduced, at the moment, the storage pressure is smaller than a preset threshold value.
In step S302, if it is a decrease, the decreased number of virtual machines is input.
Step S303, the corresponding number of virtual machine processes is terminated.
Step S304, if so, pausing the virtual machine process.
In step S305, an environment preparation module is called.
Alternatively, invoking the environment preparation module refers to invoking steps S201 to S205 to deploy a new virtual machine.
Step S306, the virtual machine process is restored.
Alternatively, the specific implementation process of step S302 to step S306 may refer to the above description, and will not be described herein.
According to the storage testing method, storage pressure caused by a plurality of virtual machines for performing storage performance testing is collected; determining whether the storage pressure is greater than a preset threshold; if the virtual machine is larger than the preset threshold value, deleting the virtual machine from the plurality of virtual machines; and if the storage performance test is smaller than the preset threshold, newly creating a virtual machine so that the newly created virtual machine and the plurality of virtual machines can perform the storage performance test. Therefore, the scale of the whole virtual machine participating in the storage performance test is dynamically adjusted according to the storage pressure and the size of a preset threshold value, and the peak performance of the server is accurately obtained.
Based on the same inventive concept, referring to fig. 4, a storage testing apparatus corresponding to the storage testing method shown in fig. 1 is further provided in the embodiment of the present application, and it should be understood that the apparatus 400 can perform the steps related to the method embodiment, and specific functions of the apparatus 400 may be referred to the above description, and detailed descriptions are omitted herein for avoiding repetition.
