Abstract

A storage network system includes computers, storage systems, connection devices that control connection relations between the computers and the storage system, and a managing device that manages the computers, the storage system and the connection devices. The managing device includes a control section that specifies connection ports of the computers, the storage system and the connection devices that compose the storage network system. Further, the control device of the managing device displays on a display section a data traffic amount at each of the connection ports for each connection path from the computer to the storage system.

Claims

1. A management computer coupled to a plurality of computers each including a port, a plurality of storage apparatuses each including a port and a plurality of switches each including a port, the switches being coupled to the computers and the storage apparatuses,

the management computer comprising:

a memory which comprises;

topological information including port identifiers of the computers, storage apparatuses and switches and performance information of the port identifiers,

a performance information collection program which collects the performance information from the computers, storage apparatuses and switches and stores the performance information, and

an analyzing program which is executable to receive a request specifying a storage apparatus which is one of the plurality of storage apparatuses and, by referring to the topological information, identify a port related to an access path which includes the specified storage apparatus;

a processor executing the performance information collection program and the analyzing program in the memory; and

an I/O device outputting the identified port and the performance information of the identified port.

2. A management computer according to claim 1,

wherein the performance information includes a traffic amount.

3. A management computer according to claim 2,

wherein the I/O device outputs a condition of the identified port.

4. A management computer according to claim 3,

wherein the condition includes a normal condition and an abnormal condition.

5. A management computer according to claim 2,

wherein the I/O device outputs a graph which shows a time-wise change of the traffic amount.

6. A management computer according to claim 5, wherein

the graph is a line graph.

7. A management computer according to claim 2,

wherein the traffic amount is an average of the traffic amount for a predetermined period of time.

8. A management computer according to claim 1,

wherein the I/O device outputs the port and the performance information in descending order of access loads to the selected storage apparatus.

9. A management computer according to claim 1,

wherein the performance information collection program collects the performance information for a predetermined period of time.
