Storage system, a method of file data back up and a method of copying of file data
First Claim
1. A storage system comprising:
- a plurality of physical input/output ports;
a control unit coupled to the plurality of physical input/output ports; and
a plurality of disk drives coupled to the control unit,wherein a first port of the plurality of physical input/output ports is accessible by both a block I/O request via an IP network and by a file I/O request via the IP network, andwherein the plurality of disk drives are configured into a first logical volume assigned to store data related to the block I/O request and a second logical volume assigned to store data related to the file I/O request based upon information contained in the block I/O request or the file I/O request.

Abstract
A storage system manages the total capacity of a shared storage medium to store block-basis data and file-basis data. When block data and its address are input through a fiber channel port, an input/output unit converts its data format to a data format that is internally applied by the storage system. When file data and its address are input, a file system converts its data format to a block data format internally applied by the storage system. The file system derives a file logical volume address from the received file address and translates file data to block data. A managing unit derives the address of a block logical volume from the block address delivered from the input/output unit. The managing unit translates block logical volume address or the file logical volume address to a physical address, and writes data to or reads data from the shared storage medium.

12. A storage system to be coupled to an IP network, said storage system comprising:
-
a plurality of physical input/output ports to be coupled to the IP network; a control unit coupled to the physical input/output ports; and a plurality of disk drives coupled to the control unit, wherein a first port of the physical input/output ports is accessible by both a block I/O request via the IP network and by a file I/O request via the IP network, wherein the physical input/output ports include a second port being accessible by a block I/O request and a third port being accessible by a file I/O request, and wherein the plurality of disk drives are configured into a first logical volume assigned to store data related to the block I/O request and a second logical volume assigned to store data related to the file I/O request based upon information contained in the block I/O request or the file I/O request. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
