Problems solved by technology

However, it does not consider the bearing capacity of various LUNs (Logical Unit Numbers, volumes) in the storage system, such as common volumes and remote replication volumes. If the host layer issues IOPS (Input / Output Operations Per Second, the The number of times) is too large, resulting in resource competition between volumes, which is likely to cause instability in IO data transmission and affect the processing speed of the host layer

Embodiment 1

[0041] see figure 1 , figure 1 It is an implementation flowchart of the data transmission method in the embodiment of the present invention, and the method may include the following steps:

[0042] S101: When receiving an IO data processing command from the host layer, parse the IO data processing command to obtain corresponding target volume priority identification information.

[0043] The priority of each volume in the storage device can be set in advance, and when the host layer needs to write IO data to the corresponding volume of the storage device, or need to read IO data from the corresponding volume of the storage device, it can send IO data to the storage device The command is processed, and the priority identification information of the target volume that needs data transmission is embedded in the IO data processing command. The storage device receives the IO data processing command, and when receiving the IO data processing command issued by the host layer, parse...

Embodiment 2

[0053] see figure 2 , figure 2 It is another implementation flowchart of the data transmission method in the embodiment of the present invention, and the method may include the following steps:

[0054] S201: When receiving an IO data processing command from the host layer, analyze the IO data processing command to obtain corresponding target volume priority identification information.

[0055] S202: Store the IO data processing command in a target information queue at a level corresponding to the priority identification information of the target volume.

[0056] S203: Utilize each target thread pre-allocated for the target information queue to respond to the IO data processing command according to the preset target IOPS and target bandwidth.

[0057] You can pre-set the corresponding IOPS and bandwidth for the threads corresponding to the volumes of each priority level. For example, you can set the IOPS and bandwidth of the threads corresponding to the high-priority volum...

Abstract

The invention discloses a data transmission method which comprises the following steps: when an IO data processing command issued by a host layer is received, parsing the IO data processing command toobtain corresponding target volume priority identification information; storing the IO data processing command into a target information queue of a level corresponding to the target volume priority identification information; and responding to the IO data processing command by utilizing each target thread pre-distributed for the target information queue. By applying the technical scheme providedby the embodiment of the invention, the resource competition between volumes is avoided, the stability of IO data transmission is greatly improved, and the processing speed of a host layer is greatlyimproved. The invention further discloses a data transmission device and equipment and a storage medium, which have corresponding technical effects.

Description

technical field [0001] The present invention relates to the field of computer application technology, in particular to a data transmission method, device, equipment and computer-readable storage medium. Background technique [0002] With the rapid development of computer technology, many technologies have been greatly improved, especially the successful use of back-end storage system partitions, which meets the security and stability requirements of the data sent by the server host. Moreover, the successful use of cache memory and flash memory meets the requirements for computing resources and computing speed in the field of computer technology, and this processing method greatly accelerates the speed of data processing. However, the common IO data transmission method between the host and the storage system enhances the data transmission efficiency between the host layer and the storage system. However, it does not consider the bearing capacity of various LUNs (Logical Unit...
