ABSTRACT:
A system for monitoring performance of an intelligent array expansion system includes a controller for communicating with a host computer and associated intelligent array expansion systems, each of which has a plurality of fixed disk drives. The controller incorporates firmware to monitor a plurality of predetermined performance data, such data being thereafter stored in information storage devices. At the same time counts are maintained for selected parameters which are of interest to a systems manager. Such counts and the performance data are stored for each one of a plurality of preselected intervals, and an indication or warning is given to the systems manager when performance data, or when a selected parameter exceeds a preselected threshold.
