Abstract
Network arrangements wherein a network interface receives write requests of files of a file system from a client computer, each file including respective data and respective metadata. A processor registers the metadata of a file to at least one first type storage medium and writes the data of the file to the at least one second type storage medium based on file value information. The storage system stores information of address ranges of an integrated logical unit, in which each address range corresponds to the at least one first type storage medium and the at least one second type storage medium included in the integrated logical unit, and provides the information of address ranges of the integrated logical unit to the client computer.
