Abstract: 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.

Abstract translation: 提供了一种用于处理I / O请求和计算机系统的方法。 该方法包括：从虚拟机接收I / O写请求; 将要写入的I / O写请求写入的第一数据写入本地持久存储区; 确定第一数据所属的文件的文件类型; 以及如果所述第一数据所属的文件的文件类型是用户文件或系统文件，则将所述第一数据写入远程共享存储区域。 因此，可以减少远程共享存储区域上的访问流量。
