Embodiment Construction

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0049] At present, the transmission efficiency between the virtual network card virtualized based on virtio and the host is slow, and it also needs to rely on the hardware resources of the original physical network card. Therefore, the present application provides a data processing solution, which can virtualize at least two virtual network cards based on the NVMe namespace and one physical network card, improve the transmission efficienc...

Abstract

The application discloses a data processing method, device, equipment and readable storage medium. This application virtualizes at least two virtual network cards based on the NVMe namespace and one physical network card, then the host and any virtual network card can interact based on the SQ queue and CQ queue in the host memory. Specifically, the host can directly transmit the specific location of data in the host memory to a certain virtual network card, then the virtual network card can directly obtain the required data, so transmitting a command between the host and the virtual network card requires an interaction between the two. Completed, improving the transmission efficiency between the host and the virtual network card. At the same time, the virtual network cards virtualized based on the NVMe namespace do not need to occupy the hardware resources of the original physical network card, thus reducing the hardware resource occupation of the original physical network card by the virtual network card. Correspondingly, a data processing device, device, and readable storage medium provided by the present application also have the above-mentioned technical effects.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a data processing method, apparatus, device, and readable storage medium. Background technique [0002] Currently, based on virtio+SRIOV, one physical NIC on the host can be virtualized into multiple virtual NICs. However, the data transmission efficiency of the virtual network card virtualized by SRIOV is slow. The specific performance is: if the host needs to transmit a command to a virtual network card, the host needs to first transmit to the virtual network card a descriptor related to the command, and then transmit to the virtual network card a descriptor indicating the host memory address where the command is located. , and also need to transmit relevant data to the virtual network card. It can be seen that the transmission of a command between the host and the virtual network card requires three interactions between the two to complete, and the transmiss...
