Abstract: A data distribution method and a splitter is provided. The data distribution method executed by the splitter includes: parsing a received data packet to determine a transport layer communications protocol to which the data packet belongs; acquiring from the data packet, identification information of a data stream to which the received data packet belongs; acquiring from a memory according to a correspondence between a transport layer communications protocol and an distribution table, an distribution table corresponding to the transport layer communications protocol to which the data packet belongs; determining according to a correspondence between identification information of a data stream and a thread in the acquired distribution table, a thread corresponding to the data stream to which the data packet belongs; and sending the data packet to a cache queue of the determined thread, so that the determined thread acquires the data packet from the cache queue.

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.
