## 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 computer system comprising:
a host computer having a plurality of host ports;
a storage system having a plurality of storage ports and a plurality of volumes; and
a management computer, coupled to the host computer and the storage system, and having access path information indicating a plurality of access paths, each including a set of one of the plurality of host ports ,one of the plurality of storage ports, and one of the plurality of volumes,
wherein the management computer stores a traffic amount of the plurality of host ports and the plurality of storage ports,
wherein the management computer receives a first request specifying a certain volume which is one of the plurality of volumes, specifies plural parts of the plurality of access paths each including the certain volume, and displays a part of the traffic amount of the plurality of host ports and the plurality of storage ports, corresponding to the plural parts of the plurality of access paths.

### Claim 2 (depends on 1)

A computer system according to claim 1, wherein the management computer receives a second request specifying a certain access path which is one of the plurality of access paths, calculates a traffic amount of the certain access path with a currently used access path which is one of the plurality of access paths, and displays the traffic amount of the certain access path.

### Claim 3 (depends on 2)

A computer system according to claim 2, wherein the traffic amount of the plurality of host ports and the plurality of storage ports is based on information collected from the host computer and the storage system.
