Embodiment Construction

[0027] figure 1 It is a flow chart of a method for optimizing storage performance of a storage array provided by an embodiment of the present invention, and the method includes:

[0028] Step 11, reading the information set collected in advance during the operation of the storage array;

[0029] For example, before the storage array is optimized, information generated during operation of the storage array is collected, such as input and output (IO) information, cache information, controller load information, and the like. And save this information to form an information collection. When using the information set to optimize the storage array, the information set is read first.

[0030] Step 12. According to the feature value of the information in the information set, perform information classification on the information set to obtain information categories;

[0031] Wherein, the characteristic value of the information is different according to different information. For ex...

Abstract

The invention relates to a method and a device for optimizing the storage performance of a storage array and a storage device. The method comprises the following steps of: reading an information set preliminarily collected in the operation process of a storage array; classifying the information of the information set according to information eigenvalues in the information set to acquire an information category; counting the probability value of the acquired information category; respectively comparing the probability value of the information category with a preset threshold value; and using an eigenvalues of the information category with a probability value satisfying the threshold value as an optimizing value to optimize the storage array. The invention reads and analyzes the preliminarily collected information set to acquire the optimizing value, optimizes according to the generated optimizing value, automatically optimizes the storage performance of the storage array and improves the optimization efficiency of the storage performance.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a method and device for optimizing storage performance of a storage array, and a storage device. Background technique [0002] Due to the variability of the upper-layer application of the storage array, the default storage configuration or several preset configurations cannot optimize the storage performance of the storage array. Based on these statistical information, personnel conduct manual analysis, formulate optimization plans and implement them. Afterwards, test the storage array after implementing the optimization plan. If the storage performance meets the requirements, the optimization ends; otherwise, continue the analysis and optimize again. [0003] During tuning, since performance tuning personnel such as storage performance engineers and performance tuning engineers need to infer storage performance problems based on various information from performance statist...
