Problems solved by technology

Volumes in block storage carry the main IO services, but currently the use of volumes is dominated by a single path. Each volume usually has only one IO path for read and write access. This mode will limit the volume’s bandwidth and IOPS (Input / Output Operations Per Second, read and write times per second) and other performance

Embodiment approach

[0060] In the above-mentioned embodiment, there is no limitation on how to execute step S103. This embodiment also provides an optional implementation manner of the storage performance data storage operation, which may include the following steps:

[0061] Pre-create the performance statistics object for storing performance data, that is, the Perf object. The storage performance data stored in the performance statistics object takes the IO path in each volume as a collection; each collection stores the storage performance data of all volumes of the corresponding IO path . Please participate in the organization of the data stored in the Perf object figure 2 Shown: The IO performance data stored in Perf takes the IO path in each volume as a collection. Each collection stores the IO performance data of the path.

[0062] When the collected performance statistics data has accumulated to a preset number threshold, all storage performance data is stored in the performance statist...

Abstract

The invention discloses a data access method and device, electronic equipment and a readable storage medium. The method is applied to a distributed object storage block device, and comprises the following steps: pre-constructing a plurality of IO paths, and setting unique identification information for each IO path; when an IO request is received, visiting a target volume by using a plurality of IO paths, and collecting storage performance data of each IO path at the same time; and when the method detects that the performance data storage condition is met, taking the identification information of each IO path as a storage key value, and executing storage operation on the collected storage performance data. According to the method and the device, the accurate storage performance data can be obtained while the data access efficiency is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data access method, device, electronic equipment and readable storage medium. Background technique [0002] With the rapid development of cloud services such as OpenStack and k8s, distributed block storage plays an increasingly important back-end storage task. Volumes in block storage carry the main IO services, but currently the use of volumes is dominated by a single path. Each volume usually has only one IO path for read and write access. This mode will limit the volume’s bandwidth and IOPS (Input / Output Operations Per Second, the number of reads and writes per second) and other performance. Inevitably, users will call storage performance data, or visualize storage performance data to users, all of which involve the acquisition of storage performance data. [0003] In view of this, how to achieve accurate acquisition of storage performance data while improving...
