Storage network system, managing apparatus, managing method and program

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.

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;
