METHOD FOR PROCESSING INPUT/OUTPUT REQUEST, HOST, SERVER, AND VIRTUAL MACHINE

摘要

A method for processing an I/O request and a computer system are provided. The method includes: receiving an I/O write request from a virtual machine; writing first data to be written as requested by the I/O write request into a local persistent storage area; determining a file type of a file to which the first data belongs; and writing the first data into a remote shared storage area if the file type of the file to which the first data belongs is a user file or a system file. Thus access traffic on the remote shared storage area can be reduced.
