  comment = {Compares four different ways of restructuring IBM disk controllers
  and channels to obtain more parallelism. They use parallel heads or parallel
  actuators. The best results come when they replicate the control electronics
  to maintain the number of data paths through the controller. Otherwise the
  controller bottleneck reduces performance. Generally, for large or small
  transfer sizes, parallel heads with replication gave better performance.}
