Computing system and method of changing i/o configuration thereof

Abstract

A computing system includes: first and second I/O interfaces that are associated with a server; and an I/O management unit that connects the server with the first and second I/O interfaces. The I/O management unit includes: an I/O buffer; an I/O mapping unit that stores an access request of the server to the first I/O interface in the I/O buffer in response to a change start request of the first I/O interface associated with the server to the second I/O interface; an I/O changing unit that associates the second I/O interface with the server; and an I/O synchronizing unit that converts the access request stored in the I/O buffer into an access request to the second I/O interface, in response to the completion of the association by the I/O changing unit, and executes the converted access request.

1 . A computing system comprising:
 a first I/O interface associating with a server; and   an I/O management unit coupled with the server and the first I/O interface, the I/O management unit including:   an I/O buffer;   an I/O mapping unit which stores an access request of the server to the first I/O interface in the I/O buffer in response to a change start request of the first I/O interface associated with the server to a second I/O interface to be associated with another server;   an I/O changing unit which associates the second I/O interface with the another server; and   an I/O synchronizing unit that converts the access request stored in the I/O buffer into an access request to the second I/O interface associated with the another server, in response to the completion of the association by the I/O changing unit, and executes the converted access request.
