Drive Movement
An array of drives can be moved from one system to another. For more
information, see Chapter 2, “Guidelines for Making Changes to Current
Installation.”
SCSI Device Support
The Smart Array 3200 Controller complies with ANSI SCSI-2 standards and
supports 16-bit Wide-Ultra2 SCSI, 16-bit Wide-Ultra SCSI-3, 16-bit Fast-Wide
SCSI-2, and 8-bit Fast SCSI-2 (standard SCSI) devices.
Wide-Ultra2 SCSI
Wide-Ultra2 technology provides data transfer rates of up to 80 MB/sec at a
40-MHz bus rate. This combination allows higher throughput in many network
application environments than does Wide-Ultra SCSI-3.
Wide-Ultra SCSI-3
Wide-Ultra SCSI-3 technology provides SCSI data transfer rates of up to
40 MB/sec at a 20-MHz bus rate. This combination allows high throughput in
many network application environments, including resource sharing and
database servicing.
Fast-Wide SCSI-2 and Fast SCSI-2
Fast-Wide SCSI-2 provides two bytes of data at each bus transfer, providing a
maximum data rate of 20 MB/sec between SCSI devices while maintaining a
10-MHz bus rate.
Fast-Wide SCSI-2 controllers and devices communicate using Fast SCSI-2
protocol when required. Fast SCSI-2 drives are supported by the Smart Array
3200 Controller using the appropriate cable adapter.
