Problems solved by technology

[0003] However, the traditional multi-path storage system is relatively backward in the path selection method, which is often the following: 1. Randomly select a normal path as the working path; 2. Select the current data pressure as the working path; 3. Select no history The path with the fewest tasks as the working path, etc.

Embodiment Construction

[0026] The technical solution in this application will be described below with reference to the accompanying drawings.

[0027] It should be understood that the following first and second are only for distinguishing different description objects, such as different paths, and are not limited in this application.

[0028] figure 1 A schematic flow chart showing a method of an embodiment of the present application, such as figure 1 As shown, the method includes:

[0029] Step 110, determine multiple candidate paths according to the data to be sent and the data already sent.

[0030] Step 120, according to the data throughput of each candidate path in the plurality of candidate paths, determine the first path from the plurality of candidate paths as the current working path.

[0031] Specifically, according to the data to be sent and the data that has been sent, effective paths that can provide services for the data to be sent are determined, and these effective paths that can ...

Abstract

The embodiment of the invention provides a method for determining a working path. The method comprises the following steps that: according to data to be set and sent data, determining a plurality of candidate paths; and according to the data throughout of each candidate path in the plurality of candidate paths, determining a first path in the plurality of candidate paths as a current working path.Therefore, by use of the method provided by the embodiment of the invention, after the plurality of candidate paths are selected, the working path can be selected according to the data throughout situation of each candidate path, and the data to be sent can be more reasonably transmitted.

Description

technical field [0001] The present application relates to the field of information processing, and more specifically, relates to a method and device for determining a working path. Background technique [0002] A storage device is an essential core component in a computer system. There is a one-to-one correspondence between ordinary storage devices and computing devices, that is, a computing device accesses a certain storage device through a path. At this time, if the line between the computing device and the storage device fails, the storage device is in an unavailable state for the computing device. Storage multipath means that a computing device can access the same storage device through multiple paths. For multi-path storage, as long as all paths do not fail at the same time, the storage device is available to the computing device, which greatly improves the security and reliability of data. [0003] However, the traditional multi-path storage system is relatively back...
