Embodiment 1

[0033] like figure 1 As shown, the method of constructing hotspot data testing data layering based on Vdbench includes the following steps:

[0034] S1, create a storage pool, and create RAID with different performance in the storage pool:

[0035] The creation of the storage pool is realized through mkmdiskgrp, such as mkmdiskgrp–name TierPool, that is, a storage pool named TierPool is created.

[0036] RAIDs with different performances are created in the TierPool storage pool by using disks with different performances. For example, use high-performance disks to create RAID10 and low-performance disks to create RAID5. Use SSDs for high-performance disks and SAS for low-performance disks. A high-performance data layer SSD layer and a low-performance data layer SAS layer are formed. For example:

[0037] mkarray –level raid10 –drive 1 2 3 4

[0038] mkarray –level raid5 –drive 5 6 7

[0039] Among them, 1, 2, 3, and 4 are SSD disk ids (identification, identification), and ...

Embodiment 2

[0054] Such as figure 2 As shown, on the basis of embodiment 1, this embodiment also includes steps:

[0055] After the second set time elapses, the stratification of the hotspot data is checked.

[0056] The second setting time is greater than the first setting time. In the actual test process, due to broadband and other reasons, the migration rate of test data is often affected. Therefore, in order to ensure the accuracy of the test results, the second setting time is set. 2. After setting the time, obtain the storage capacity of disks with different performance, and check the layering of hot data according to the change of disk storage capacity. If the free capacity of the low-performance data layer increases, the free capacity of the high-performance data layer decreases, indicating low-performance data. The data in the high-performance data layer has been migrated to the high-performance data layer, that is, the hotspot data has been stratified. If the free capacity of ...

Abstract

The embodiment of the invention discloses a method for constructing test data hierarchy of hot spot data based on Vdbench, the method comprising the steps of creating a storage pool and creating RAIDwith different performance in the storage pool; creating a LUN in the storage pool and mapping the LUN to a host; obtaining and recording the storage capacity of disks with different performance; constructing a Vdbench configuration file according to the hot spot data proportion, and distributing the hot spot service to the LUN.; after the elapse of the first set time, checking the hot spot data hierarchy. A Vdbench test tool is used to construct a configuration file, and the construction of hot spot data greatly simplifies the test steps and shortens the time of hot spot data construction. Atthe same time, the function of data stratification is tested effectively and accurately, the test of data stratification is simplified, and time and human cost are saved without human participation in the test process.

Description

technical field [0001] The invention relates to the technical field of computer storage, in particular to a method for constructing hotspot data and testing data layers based on Vdbench. Background technique [0002] With the rapid development of the IT (Information Technology, information technology and industry) industry, the development of informatization, big data and cloud computing has higher and higher requirements for the scale and performance of storage systems, and data layering technology is widely used in In response to the continuous expansion of storage scale, the response time of query information increases accordingly. [0003] In the storage system, frequently used hot data is migrated to disks with higher performance, and infrequently used data is migrated to disks with relatively low performance, so as to maximize the performance of the entire storage system. This function is Data layering. [0004] In order to test the data layering function, testers ne...
