The programs exiting in design of data migration time are analyzed.This study determines migration time and designs the monitor of data migration by introducing mathematical formula estimating the change of the storage capacity,and combining with transmission rate of storage system and storage capacity,so a theory method about the design of migration time is provided.Meanwhile,two-tier storage is built in high performance computing environment.According to the design of migration time,the data migration strategy is disposed in the tiered storage.The result indicates that this design could ensure the timely migration of the data in tiered storage,effectively reduce the migration blocking and improve the utilization rate of storage.
