Abstract: PROBLEM TO BE SOLVED: To allow an open system host to obtain desk activity ratio characteristics by transferring a parameter pertaining to a disk array to a host so as to calculate a disk activity ratio on the basis of this parameter. SOLUTION: An open system host 204 communicates with a disk subsystem 202 by being connected with a processor 210 through an Internet connection. A specialist 212 in the processor 210 collects parameters pertaining to disk characteristics. This parameter is transferred to an expert 214 in the host 204. The expert 214 calculates a disk activity ratio from the parameter. This calculation is executed by a disk activity ratio routine 216 in the expert 214. The disk activity ratio is displayed in the from of a report by the expert 214 with other disk characteristics.

Abstract: The present invention provides a method and system for reporting disk utilisation in a computer system (200). The method includes collecting at least one parameter pertaining to a disk array (206) in a disk subsystem (202) by a processor (210) in the disk subsystem (202); transferring the at least one parameter from the processor (210) to an open system host (204); and calculating disk utilisation based upon the at least one parameter. The method and system is able to provide disk utilisation which is understandable to the open system host (204). In a preferred embodiment, the disk utilisation is provided by collecting the relevant parameters from the microcode in the processor (210) of the disk subsystem (202), and then calculating the average disk utilisation per disk based upon the parameters. Thus, an open system host (204) is able to obtain a useful characteristic for determining the performance of the disk subsystem.
