Embodiment Construction
[0048] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0049] At present, the transmission efficiency between the virtual network card virtualized based on virtio and the host is relatively slow, and it still needs to rely on the hardware resources of the original physical network card. To this end, this 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 efficiency between the host and the virtual netw...

The invention discloses a data processing method and device, equipment and a readable storage medium. According to the method, at least two virtual network cards are virtualized based on the NVMe namespace and one physical network card, so that the host and any virtual network card can interact based on the SQ queue and the CQ queue in the host memory. Specifically, the host can directly transmit the specific position of the data in the host memory to a certain virtual network card, and then the virtual network card can directly obtain the required data, so that the transmission of a command between the host and the virtual network card can be completed by one-time interaction between the host and the virtual network card, and the transmission efficiency between the host and the virtual network card is improved. Meanwhile, the virtual network cards virtualized based on the NVMe namespace do not need to occupy hardware resources of the original physical network card, so that occupation of the hardware resources of the original physical network card by the virtual network cards is reduced. Correspondingly, the invention provides a data processing device and equipment and a readable storage medium, which also have the above technical effects.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular to a data processing method, device, equipment 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 relatively slow. The specific performance is: if the host needs to transmit a command to a certain 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 then , it is also necessary 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 t...
