Abstract

The invention discloses a data transmission method and a data forwarding device. The method includes the steps that the data forwarding device receives control instructions sent by virtual machines, wherein the control instructions are used for instructing N channels among multiple channels arranged between the data forwarding device and storage devices to be opened in advance, and one channel corresponds to one or more storage devices; the data forwarding device opens the N channels according to the control instructions, wherein the number of the opened N channels is matched with that of thevirtual machines; after the data forwarding device opens the N channels, the data forwarding device receives data to be transmitted from the virtual machines; the data forwarding device transmits thedata to be transmitted to the storage devices through the opened N channels. By means of the data transmission method and the data forwarding device, the technical problem of low system performance when the virtual machines directly transmit data to the storage devices is solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a data transmission method and a data forwarding device. Background technique [0002] QEMU is an efficient and practical simulation processor, which can simulate a virtual machine running independently, and is one of the mainstream virtualization technologies at present. [0003] Ceph is a high-performance, high-reliability and high-scalability distributed file system, which can provide high-reliability and elastically expandable storage devices for virtual machines. [0004] When QEMU connects to Ceph storage and reads and writes to the Ceph storage device, threads will be generated, and the number of threads generated is proportional to the number of virtual machines and storages enabled. When the number of virtual machines enabled and the number of storages connected to the virtual machine When there are fewer threads, there are fewer threads, system resources are idle, and ...
