Multi-computer computing device supporting virtual machine to share IO equipment and IO equipment sharing method thereof

Abstract

The invention discloses a multi-computer computing device supporting a virtual machine to share IO equipment and an IO equipment sharing method thereof. The device comprises a management node, a plurality of computing nodes, a plurality of IO nodes and a PCIe switching node. Wherein each IO node comprises a PCIe device; wherein the management node, the computing node and the IO node are interconnected through the PCIe exchange node; and the management node enumerates, configures and manages PCIe equipment on the IO node through the PCIe switching node, and the computing node accesses the IO equipment through the PCIe switching node and transparently transmits the IO equipment to the virtual machine running on the node. According to the sharing method, the IO equipment of the device is shared by the virtual machine, and the migration of the virtual machine is supported, so that the same IO equipment can be accessed on different computing nodes. The method is easy to implement, physicalIO equipment can be shared by multiple machines, and virtual equipment can be shared by multiple machines through the SR-IOV technology.

Description

technical field [0001] The invention belongs to the field of IO equipment sharing, and in particular relates to a multi-computer computing device supporting virtual machines to share IO equipment and an IO equipment sharing method thereof. Background technique [0002] With the development of cloud computing technology and popularization of applications, cloud computing centers have become an important part of modern information systems. In the cloud computing center, how to realize resource sharing and improve resource utilization is an important research direction. [0003] In order to improve resource utilization, cloud computing generally adopts virtualization technology to virtualize physical servers into multiple virtual machines for users to use. The current virtualization technology is mainly for virtualization of stand-alone systems, such as Intel's VMX technology, AMD's SVM technology, etc., which can virtualize a physical processor into multiple virtual processor...

AI Technical Summary

Problems solved by technology

The current virtualization technology is mainly for virtualization of stand-alone systems, such as Intel's VMX technology, AMD's SVM technology, etc., which can virtualize a physical processor into multiple virtual processors, and access the local IO devices through transparent transmission; However, this type of technology cannot realize the sharing of IO devices between multi-computer systems

In response to the problem, the PCI-SIG open source organization released the Multi-Root IO Virtualization Specification (MR-IOV, Multi-Root IO Virtulization) to realize the sharing of IO devices between multi-machine systems, but there is no mature support for MR-IOV at present.
