  comment = {Measuring the performance of a RAID prototype with a Sun4/280, 28
  disks on 7 SCSI strings, using 4 HBA controllers on a VME bus from the Sun.
  The found lots of bottlenecks really slowed them down. Under Sprite, the
  disks were the bottleneck for single disk I/O, single disk B/W, and string
  I/O. Sprite was a bottleneck for single disk I/O and String I/O. The host
  memory was a bottleneck for string B/W, HBA B/W, overall I/O, and overall
  B/W. With a simpler OS, that saved on data copying, they did better, but were
  still limited by the HBA, SCSI protocol, or the VME bus. Clearly they needed
  more parallelism in the busses and control system.}
