In a virtualization system, physical volumes are virtualized between servers (101, 102) and storage systems (106) such that even when high-performance functions including a remote copy are provided, a virtualization unit does not become a bottleneck of processing. For this purpose, a virtualization node (103) to conduct virtualization includes at least one virtualization switch (105) which receives data from a server and converts the data into data for a real volume to send the data to an associated storage and which receives data from a storage and converts the data into data from a virtualized volume to send the data to a server and at least one virtualization server (104) which receives data requiring processing such as a remote copy from the virtualization switch, performs a particular processing for the data, and then transmits the data via the switch to a server or a storage.
