Abstract

A management computer includes a memory storing toplogical information including identifiers of ports of computers, storage apparatuses, and switches. The management computer includes a processor, which is configured to: collect a plurality of performance information of the ports, and a plurality of access times from computer ports to the storage apparatuses; evaluate that a certain access time among the plurality of access times exceeds a predetermined allowable range; search a first access path to which the certain access time corresponds; search at least one second access path starting from a first computer port on the first access path; and search performance information of certain ports which are on the at least one second access path in order to display the searched performance information.

Claims

1. A management computer comprising:

a memory storing;

(A) toplogical information including identifiers of ports of computers, storage apparatuses, and switches;

a processor, which is configured to;

(B) collect a plurality of performance information of the ports, and a plurality of access times from computer ports to the storage apparatuses;

(C) evaluate that a certain access time among the plurality of access times exceeds a predetermined allowable range;

(D) search a first access path to which the certain access time corresponds;

(E) search at least one second access path starting from a first computer port on the first access path; and

(F) search performance information of certain ports which are on the at least one second access path in order to display the searched performance information.

2. A management computer according to claim 1,

wherein the processor is configured to:

(G) collect a plurality of condition information of the ports; and

(H) display identifiers of the certain ports and condition information among the certain ports in addition to the display of the searched performance information.

3. A management computer according to claim 1,

wherein, as the display of the searched performance information, the processor is configured to:

(F1) display a graph of the searched performance information; and

(F2) display a value of the searched performance information.

4. A computer-readable medium comprising code that when executed causes a management computer to:

(A) store toplogical information including identifiers of ports of computers, storage apparatuses, and switches;

(B) collect a plurality of performance information of the ports, and a plurality of access times from computer ports to the storage apparatuses;

(C) evaluate that a certain access time among the plurality of access times exceeds a predetermined allowable range;

(D) search a first access path to which the certain access time corresponds;

(E) search at least one second access path starting from a first computer port on the first access path; and

(F) search performance information of certain ports which are on the at least one second access path in order to display the searched performance information.

5. A computer readable medium according to claim 4,

wherein the computer-readable medium comprises further code that when executed causes the management computer to:

(G) collect a plurality of condition information of the ports; and

(H) display identifiers of the certain ports and condition information among the certain ports in addition to the display of the searched performance information.

6. A computer readable medium according to claim 4,

wherein, for the display of the searched performance information, the computer-readable medium comprises further code that when executed causes the management computer to:

(F1) display a graph of the searched performance information; and

(F2) display a value of the searched performance information.

7. A system comprising:

computers;

storage apparatuses storing data for the computers;

switches coupled to the computers and storage apparatuses; and

a management computer configured to;

(A) store toplogical information including identifiers of ports of the computers, the storage apparatuses, and the switches;

(B) collect a plurality of performance information of the ports, and a plurality of access times from computer ports to the storage apparatuses;

(C) evaluate that a certain access time among the plurality of access times exceeds a predetermined allowable range;

(D) search a first access path to which the certain access time corresponds;

(E) search at least one second access path starting from a first computer port on the first access path; and

(F) search performance information of certain ports which are on the at least one second access path in order to display the searched performance information.

8. A system according to claim 7,

wherein the management computer is configured to:

(G) collect a plurality of condition information of the ports; and

(H) display identifiers of the certain ports and condition information among the certain ports in addition to the display of the searched performance information.

9. A system according to claim 7,

wherein, as the display of the searched performance information, the management computer is configured to:

(F1) display a graph of the searched performance information; and

(F2) display a value of the searched performance information.
