Problems solved by technology

Since the virtual disks are uniformly managed by the remote shared storage in the data center, when a user initiates a write request to the virtual desktop environment, each virtual machine needs to update the virtual disk in the remote shared storage, and the I / O path is long, thus Causes I / O write request processing delay, affecting user experience

Abstract

The embodiment of the invention provides a method for processing an input / output (I / O) request and a server. The method comprises the following steps of receiving an input / output (I / O) write request from a virtual machine; writing first data requested to be written by the input / output (I / O) write request into a local persistent storage area; determining a file type of a file to which the first data belong; if the file type of the file to which the first data belong is a user file or a system file, writing the first data into a far-end shared storage area. According to the embodiment of the invention, by determining the file type of the file to which the first data stored in the local persistent storage area belong, the first data stored in the local persistent storage area are written into the far-end shared storage area under the condition that the file to which the first data belong is the user file or the system file, and the page view for the far-end shared storage area can be reduced.

Description

technical field [0001] The present invention relates to the field of information technology, and in particular, to a method for processing input / output (I / O) requests, a host computer, a server and a virtual machine. Background technique [0002] It has become a new requirement for users to quickly access the usual desktop environment when they work in different places, so desktop cloud solutions have been more and more widely used. In the desktop cloud solution, users can access cross-platform applications or the entire client desktop through thin clients, tablets, or other devices connected to the network, and can obtain the same experience as traditional personal computers. [0003] In the desktop cloud solution, a virtual desktop infrastructure (Virtual Desktop Infrastructure, VDI) form is usually adopted. This form of VDI adopts the principle of "centralized computing, distributed display" and supports client desktop workloads hosted in the data center, such as operati...
