Abstract

A performance information display method using a computer, includes the steps, in the computer, of reading out information data of a storage device previously stored in a storage device and information data of a plurality of devices utilizing the storage device, displaying an identifier of the storage device and identifiers of a plurality of devices utilizing the storage device on a screen on the basis of the information data read out, accepting a command to select the displayed identifier of the storage device, and displaying performance information data of the devices utilizing the selected storage device in association on the basis of the accepted command and the information data read out.

Claims

1. A management computer comprising:

a port coupled to a first computer and a second computer and a storage system including a plurality of RAID groups constructed by a plurality of disk drives;

a processor coupled to the port; and

a display device coupled to the processor,

wherein the first computer executes a first business program by using a first volume configured by the first computer and the second computer executes a second business program by using a second volume configured by the second computer,

wherein the processor receives a first performance information of the first computer calculated based on the first volume from the first computer, receives a second performance information of the second computer calculated based on the second volume from the second computer, receives a first relation information including relationship between the first volume and a first RAID group of the plurality of RAID groups from the first computer and receives a second relation information including relationship between the second volume and the first RAID group from the second computer,

wherein the processor outputs the first and second performance information so as to display the first and second performance information on the display device if the first RAID group is selected.

2. A management computer according to claim 1,

wherein the processor receives a third performance information of the plurality of RAID groups of the storage system from the storage system, and

wherein the first RAID group is selected based on the third performance information.

3. A management computer according to claim 1,

wherein the first performance information includes a number of I/Os per second of the first volume and the second performance information includes a number of I/Os per second of the second volume.

4. A management computer according to claim 2,

wherein the third performance information includes data transfer rate of the first RAID group.

5. A management computer according to claim 4,

wherein the first RAID group is selected if the data transfer rate of the first RAID group is above a predetermined threshold.
