STORAGE MANAGEMENT METHOD AND MANAGEMENT SERVER

摘要

PROBLEM TO BE SOLVED: To migrate a virtual machine in consideration of input/output (I/O) to an array group in the post-migration virtual machine. SOLUTION: A computer system has: a physical server 2 in which the virtual machine 250 is executed; a storage device 3 which has an array group 33; and a management server 1 which manages association between the virtual machine 250 and the array group 33. The computer system calculates a predicted I/O volume of the post-migration virtual machine 250. When the predicted I/O volume exceeds the maximum I/O volume of the array group 33 connected to the post-migration virtual machine 250, an array group 33 whose maximum I/O volume is less than the predicted I/O volume is retrieved.
