Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only used as examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the invention pertains.
Fig. 1 is a flowchart of steps of a VDI scenario-based storage system IOPS performance evaluation method according to an embodiment of the present invention, and referring to fig. 1, the method includes the following steps:
s1, obtaining the storage configuration of the current storage system, and calculating the overall IOPS of the storage system according to the storage configuration.
Step S1 may specifically be:
s1.1, acquiring the number of disk groups in each RAID mode in the current storage system and the number and types of hard disks in each disk group.
S1.2, calculating the IOPS of a single hard disk according to the hard disk type;
the IOPS calculation for a single hard disk is as follows:
DISK_IOPS＝1000MS/(Seek-Time+Rotational-Time)，(1)
in equation (1), DISK _ IOPS is IOPS of a single DISK, seek-Time is Seek Time, which is described in the specification of the DISK, rotational-Time is Rotational delay, rotational-Time =60 × 1000/RPM/2, RPM is DISK RPM, which is described in the specification of the DISK.
S1.3, determining write punishment according to the RAID mode, and calculating the IOPS of the disk group under each RAID mode according to the write punishment;
under the condition of not considering the read cache hit rate, the disk group read performance IOPS is equal to the read performance accumulation of all hard disks of the disk group, while the disk group Write performance IOPS affects the effective Write operation quantity due to the data redundancy caused by the RAID type, this extra Write operation overhead caused by the data redundancy is called Write Penalty Write-Penalty, and the common RAID Write Penalty is shown in the following table 1:
TABLE 1
Therefore, the disk group IOPS in each RAID mode is calculated as follows:
RAIDx_Read_IOPS＝DISK_IOPS*DISK_num*Read_RATIO，(2)
RAIDx_Write_IOPS＝DISK_IOPS*DISK_num*Write_RATIO/Write-Penalty，(3)
RAIDx_IOPS＝RAIDx_Read_IOPS+RAIDx_Write_IOPS，(4)
in the formulas (2), (3) and (4), RAIDx _ Read _ IOPS is the reading IOPS of a single DISK group with RAID mode x, DISK _ IOPS is the IOPS of a single DISK, DISK _ num is the number of DISKs, RAIDx _ Write _ IOPS is the writing IOPS of a single DISK group with RAID mode x, read _ RATIO is the DISK Read duty RATIO, write _ RATIO is the DISK Write duty RATIO, write-Penalty is the writing Penalty of the corresponding DISK group, and RAIDx _ IOPS is the single DISK group with RAID mode x.
And S1.4, calculating the overall IOPS of the storage system according to the number of the disk groups and the IOPS of each disk group.
Because the storage system is composed of a plurality of RAID disk groups, the overall storage system IOPS is calculated as follows:
in equation (5), STORAGE _ IOPS is the sum of all disk groups IOPS of the STORAGE system, i.e. the total IOPS of the STORAGE system.
S2, acquiring the number of VDI desktops and service requirements of the current VDI scene, and calculating the overall requirements IOPS of the VDI scene.
Step S2 may specifically be:
s2.1, dividing the VDI desktop into a plurality of different types according to business requirements;
the enterprise informatization department can divide the desktop into a plurality of types according to the desktop bearing service, for example, a certain aviation manufacturing enterprise divides the VDI desktop into an OA light-load office desktop, a two-dimensional middle-load design desktop and a three-dimensional heavy-load design desktop, wherein the OA light-load office desktop mainly depends on Web browsing to develop the services such as mails and OA; the two-dimensional medium-load and three-dimensional heavy-load desktop mainly adopts modeling and simulation computing services such as CAD or CAE.
And S2.2, acquiring the number of the VDI desktops of different types, and calculating the overall performance requirement of the VDI scene IOPS according to the IOPS requirement corresponding to the preset VDI desktops of different types.
The overall demand IOPS calculation mode of the VDI scene is as follows:
in the formula (6), VDI _ IOPS is a total VDI scene requirement IOPS, m _ IOPS is a requirement IOPS corresponding to a VDI desktop of type m, and m _ current _ num is an online concurrence number of VDI desktops of type m.
The IOPS requirements presetting mode corresponding to different types of VDI desktops is as follows:
in general, the default single data block size is 4kb in the Windows NTFS file system or Linux EXT3, and is also the default operating environment conforming to most software. In order to ensure the performance evaluation accuracy of the IOPS, the IOPS performance test is carried out during the service development period of the desktop in the optimal way, the test principle is that the reading and writing operation is continuously carried out on data blocks with fixed sizes under the environment of an operating system, and the IOPS in the current state is obtained after the reading and writing values are constant. In the testing process, read and write operations, sequence and random quota ratio need to be considered, so the cloud desktop scene is generally developed by adopting the following test cases:
example 1: the operating system only carries out sequential reading operation under the size of a 4KB file block, and the operating system only carries out data reading in the storage system at the moment;
example 2: the operating system only carries out random reading operation under the size of a 4KB file block, and at the moment, the operating system only carries out data reading in the storage system;
example 3: the operating system only carries out sequential write operation under the size of a 4KB file block, and the operating system only carries out data write in the storage system at the moment;
example 4: the operating system only carries out random write operation under the size of a 4KB file block, and at the moment, the operating system only carries out data write in the storage system;
example 5: the operating system performs sequential \ random and read \ write operations under the size of a 4KB file block, the read-write and sequential random quota accounts for 50%, and at the moment, the operating system can simultaneously perform sequential \ random and read and write operations in the storage system;
in addition, to further ensure the accuracy of the test results, a single test case needs to be tested repeatedly for not less than 10 times, and then an average value is calculated as final output data, and the test results are shown in table 2:
TABLE 2
According to the average test value obtained by the test case, the IOPS performance requirement of the m-type single desktop can be calculated by adopting the following formula:
m_IOPS＝m_WRITE_IOPS+m_READ_IOPS＝5(a+b+c+d+e)/2。(7)
and S3, evaluating whether the performance of the storage system IOPS meets the requirement according to the overall IOPS of the storage system and the overall requirement IOPS of the VDI scene.
And calculating the ratio of the overall IOPS of the storage system to the overall demand IOPS of the VDI scene, and judging that the demand is met if the ratio is greater than a set value.
It should be noted that, the steps are arranged according to a streaming layout, which is only one embodiment of the present invention, and may also be arranged in other manners, and the present invention is not limited to this.
The embodiment of the invention has the following technical effects:
the first is to provide a scientific storage system overall IOPS evaluation model, which fully considers coping strategies of different RAID types and is applicable to distributed storage and centralized storage.
And secondly, providing a reasonable VDI scene overall demand IOPS evaluation model, and rapidly evaluating the real IOPS overall demand of each type of VDI scene of the enterprise according to the calculation method.
Thirdly, based on a storage system overall IOPS evaluation model and a VDI scene overall demand IOPS evaluation model, the method can assist enterprises in providing scheme guidance for storage product type selection and overall configuration requirements, and provides decision support for budget evaluation of subsequent project construction.
In addition, for centralized storage, the SPC organization provides a unified test benchmark and standardized test flow for disk arrays, while releasing objective and authoritative performance data for IT vendors and users. The SPC-1 standard is mainly used for random read-write scenes, application scenes such as a database and a network disk are simulated to a great extent, and the SPC-1 has test data configured by various combinations of disk types and RAID modes. Therefore, the disk array IOPS capability can be more scientifically evaluated through SPC-1 data, and the calculation method is as follows:
Disk_Array_IOPS＝SPC-1_IOPS/SPC-1_disknum*Disk_Array_num，(8)
the Disk _ Array _ IOPS is a Disk Array read-write IOPS, that is, the STORAGE system overall IOPS, disk _ Array _ IOPS = STORAGE _ IOPS, SPC-1/IOPS/SPC-1/Disk is official reference data, which can be directly queried by an official, and Disk _ Array _ num is the number of disks in a Disk Array.
The beneficial effects of the above embodiment: for centralized storage, the basic test data provided by SPC organization is used for conveniently and efficiently calculating the overall IOPS of the storage system.
