## 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

### Claim 1

A management computer coupled to a system, the system comprising a plurality of network equipment including a plurality of computers, a plurality of storage systems storing data accessed from the plurality of computers, and a plurality of switches coupled to the plurality of computers and the plurality of storage systems, comprising:
a processor;
a display coupled to the processor; and
a memory coupled to the processor and storing topological information of the system,
wherein the management computer receives performance information related to traffic amount of ports of the plurality of network equipment in the system at predetermined time intervals,
wherein based on the performance information, the processor selects a particular network equipment, whose performance meets a predetermined criterion, from the plurality of network equipment in the system,
wherein the processor identifies each access path including the particular network equipment based on the topological information, and
wherein the display shows the performance information of other network equipment on each identified access path.

### Claim 2 (depends on 1)

The management computer according to claim 1, wherein the display shows information indicating a traffic amount of ports of the other network equipment on the each identified access path as the performance information.

### Claim 3 (depends on 2)

The management computer according to claim 2, wherein the processor further specifies a particular port of the ports of other network equipment, whose traffic amount is greater than a predetermined threshold.

### Claim 4 (depends on 2)

The management computer according to claim 2, wherein the display shows a list of the traffic amount of the ports of the other network equipment on the each identified access path.

### Claim 5 (depends on 2)

The management computer according to claim 2, wherein the display shows a graph of the traffic amount of the ports of the other network equipment on the each identified access path.

### Claim 6 (depends on 1)

The management computer according to claim 1, wherein a table of the topological information indicating a connection relation among the plurality of network equipment is stored in the memory.

### Claim 7 (depends on 1)

The management computer according to claim 1, wherein the predetermined criterion is a predetermined value of access time from one of the plurality of computers to one of the plurality of storage systems.
