Abstract

The present invention provides a method for referring to data by using the Internet and a storage network in combination and selecting one of the networks to be used depending on the data.

A computer 107 is connected to the Internet 101. A computer 104 is connected to the Internet 101 and a SAN 111. A disk storage 110 is connected to the computer 107 and the SAN 111. A browser 105 requests to a Web server 108 for data over the Internet 101. The Web server 108 sends an error message to the browser 105 in the case where the data address cannot be interpreted. The browser 105 requests to a Web server 106 for the data. The Web server 106 obtains a copy of the YYY image 203 on the disk storage 110 over the SAN 111 to send the copy to the browser 105.

Claims

1. A method for referring to data over a network comprising the steps of:

requesting data over the Internet by specifying a data address;

receiving an error message indicating that the data address cannot be interpreted;

requesting said data over a network between a storage and a computer by specifying said data address; and

receiving said data requested.

2. A method for referring to data to be executed by a computer after receiving an error message indicating that a data address of data requested over the Internet cannot be interpreted, the method comprising the steps of:

requesting said data over a network between a storage and a computer; and

receiving said data requested.

3. A method for referring to data over a network comprising the steps of:

judging whether or not requested data are accessible over the Internet from a data address of the data;

obtaining the requested data over the Internet if it is judged that the data are accessible over the Internet;

requesting said data over a network between a storage and a computer if it is judged that the data are not accessible over the Internet; and

receiving said data requested.

4. A system for referring to data over a network comprising client means and server means, wherein

the client means comprises:

means for requesting data over the Internet by specifying a data address; and

means for receiving an error message indicating that the data address cannot be interpreted, and

the server means comprises;

means for requesting said data over a network between a storage and a computer by specifying said data address; and

means for receiving said data requested.

5. A system for referring to data over a network comprising client means and server means, wherein

the client means comprises:

means for judging whether or not requested data are accessible over the Internet from a data address of the data; and

means for obtaining the requested data over the Internet if it is judged that the data are accessible over the Internet, and

the server means comprises;

means for requesting said data over a network between a storage and a computer if it is judged that said data are not accessible over the Internet; and

means for receiving said data requested.
