Abstract:
1. A computer-implemented method for reporting performance of a storage area network (SAN) to a computer apparatus external to the SAN, the method comprising the steps of: (A) the computer apparatus receiving from the SAN numerical values comprising a range of times for the computer apparatus to access the SAN; (B) the computer apparatus determining from the numerical values received in (A) a first range of times to access the SAN; (C) the computer apparatus determining from the numerical values received in (A) a second range of times to access the SAN, wherein all of the times in the second range are greater than all of the times in the first range; (D) the computer apparatus defining a first window of access times corresponding to SAN logical accesses from the first range of times determined in (B), each SAN logical access comprising an access to data in memory in the SAN; (E) the computer apparatus defining a second window of access times corresponding to SAN physical accesses from the second range of times determined in (C), each SAN physical access comprising an access to data in a disk drive in the SAN, wherein the first window of access times and the second window of access times are mutually exclusive; (F) the computer apparatus monitoring access time of a selected access to the SAN; (G) the computer apparatus reporting the selected access to the SAN as a SAN logical access if the access time of the selected access falls within the first window; and (H) the computer apparatus reporting the selected access to the SAN as a SAN physical access if the access time to the SAN falls within the second window.
