Abstract
A method for measuring mass storage system performance in which a mass storage system has a plurality of disk drive storage elements controlled by a disk drive controller, the controller typically having a cache memory, and the controller receiving commands and data from and returning at least data to a plurality of host computers, provides the flexibility of issuing commands to the controller in different balanced configurations from a plurality of hosts in an organized fashion. The configurations exhibit hierarchical and marginal balance.
