Controller Features

The controller is the intelligent bridge between the host and the devices in the pedestal. From the host’s perspective, the controller is simply another SCSI device connected to one of its I/O buses. Consequently, the host sends its I/O requests to the controller just as it would to any other SCSI device. Figure 2–1 shows the role of the controller between the host and the pedestal.
