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

摘要

Embodiments of the present invention provide a method for processing an I/O request and a server. The method includes: receiving an input/output 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. In the embodiments of the present invention, a file type of a file to which first data belongs is determined, where the first data is stored in a local persistent storage area; and the first data stored in the local persistent storage area is written into a remote shared storage area in a case that the file to which the first data belongs is a user file or a system file, which can reduce access traffic on the remote shared storage area.
