Storage network system

A system comprising:

• a server which executes an application program and issues an access list related to the input/output of data with the execution thereof;
• a storage device which receives an access list issued from the server and performs the input/output of data in accordance with the access list;
• a management server which performs management related to an access from the server to the storage device;
• and
• a network which interconnects the server, the storage device and the management server;
• wherein the server is equipped with an application program with the input/output of data and a device control processor which issues the access list in accordance with an access request from the application program to the storage device,
• wherein the device control processor includes an authentication ID management unit which controls an access to the storage device,
• wherein the authentication ID management unit holds an authentication ID management table including a correspondence between the access list and a corresponding authentication ID required of the management server and received therein for the need of operation of the access list, and adds an authentication ID corresponding to the access list by reference to an authentication ID management table when the access list is issued to the storage device,
• wherein the storage device includes at least a port controller which receives an access list from the server and performs the transfer of data in accordance with the access list, a cache memory which temporarily stores the data transferred from the port controller, hard disk drives each of which stores the data transferred from the cache memory, and a disk controller which controls the transfer of the data between the cache memory and each hard disk drive, all of which are configured so as to be connected to one another through an internal network,
• wherein the port controller includes an access control unit which controls an access from the server,
• wherein the access control unit holds an access control table including a correspondence between an access list received from the management server and a corresponding authentication ID necessary for operation of the access list, and when the access list is received from the server, the access control unit permits execution of the access list by reference to the access control table when a combination of the received access list and the authentication ID added thereto exists,
• wherein the management server is provided with an access management unit which manages an access from the server to the storage device in accordance with an operation phase, and
• wherein the access management unit holds an operation schedule table indicative of access lists allowed under a predetermined operation phase and an access management table including a correspondence between the access list and a corresponding authentication ID necessary for operation thereof, and when a request for an authentication ID with respect to the access list is made from the server and when the received access list is contained in the access lists allowed under the operation phase at that time, the access management unit generates an authentication ID corresponding to the access list by reference to the operation schedule table, sets the access list and the authentication ID to the access management table, transmits the access list and the authentication ID to the storage device, and transmits the authentication ID to the server.
