  abstract = {The performance modeling and analysis of disk arrays is
  challenging due to the presence of multiple disks, large array caches, and
  sophisticated array controllers. Moreover, storage manufacturers may not
  reveal the internal algorithms implemented in their devices, so real disk
  arrays are effectively black-boxes. We use standard performance techniques to
  develop an integrated performance model that incorporates some of the
  complexities of real disk arrays. We show how measurement data and baseline
  performance models can be used to extract information about the various
  features implemented in a disk array. In this process, we identify areas for
  future research in the performance analysis of real disk arrays.}
