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 coupled to a first computer which executes a first business program using a first volume configured by the first computer, a second computer which executes a second business program using a second volume configured by the second computer, and a storage system which includes a plurality of RAID groups constructed by a plurality of disk drives, the management computer comprising:

a communication device coupled to the first computer, the second computer, and the storage system;

a processor coupled to the communication device; and

a display device coupled to the processor,

wherein the processor receives a first computer performance information related to the first volume from the first computer, the first computer performance information is calculated based on the first volume,

wherein the processor receives a second computer performance information related to the second volume from the second computer, the second computer performance information is calculated based on the second volume,

wherein the processor creates a first relation information including relationship between the first volume from the first computer and a RAID group of the plurality of RAID groups from the storage system,

wherein the processor creates a second relation information including a relationship between the second volume from the second computer and the RAID group from the storage system, and

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

2. A management computer according to claim 1,

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

wherein the RAID group is selected based on the storage RAID group performance information.

3. A management computer according to claim 1,

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

4. A management computer according to claim 2, wherein the storage RAID group performance information includes a data transfer rate of the RAID group.

5. A management computer according to claim 4, wherein the RAID group is selected if the data transfer rate of the RAID group is above a predetermined threshold.

6. A computer program stored on at least one computer readable storage medium and to be implemented in at least a management computer coupled to a first computer which executes a first business program using a first volume configured by the first computer, a second computer which executes a second business program using a second volume configured by the second computer, and a storage system which includes a plurality of RAID groups constructed by a plurality of disk drives, the computer program comprising:

code for receiving a first computer performance information related to the first volume from the first computer, the first computer performance information is calculated based on the first volume,

code for receiving a second computer performance information related to the second volume from the second computer, the second computer performance information is calculated based on the second volume,

code for creating a first relation information including relationship between the first volume from the first computer and a RAID group of the plurality of RAID groups from the storage system,

code for creating a second relation information including relationship between the second volume from the second computer and the RAID group from the storage system, and

code for outputting the first and second computer performance information so as to display the first and second computer performance information on the display device if the RAID group is selected.

7. A computer program according to claim 6,

code for receiving a storage RAID group performance information of the plurality of RAID groups of the storage system from the storage system, and

wherein the RAID group is selected based on the storage RAID group performance information.

8. A computer program according to claim 6,

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

9. A computer program according to claim 7,

wherein the storage RAID group performance information includes a data transfer rate of the RAID group.

10. A computer program according to claim 9,

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