Appendix A
Small Computer System
Interface (SCSI)
This appendix describes the Small Computer System Interface terms. It is
provided to help you understand the concepts related to SCSI.
What is a host adapter?
A SCSI host adapter is a printed circuit card that provides a SCSI bus
interface to the SCSI devices installed in a computer system. The FlashPoint
host adapter has both internal and external SCSI connectors supporting both
internal and external SCSI peripheral devices.
What does SCSI stand for?
SCSI stands for Small Computer System Interface. SCSI is a computer bus
interface standard that allows a variety of computer peripheral devices such
as disk drives, CD-ROM drives and tape drives to interface to a host
computer. SCSI-1, SCSI-2 and SCSI-3 are different version of the SCSI
protocol standard.
• SCSI-1 is the original standard that defines the SCSI interface. This
standard includes the definition of a command set, the electrical
characteristics of the SCSI bus, and a 5 megabytes per second data
transfer rate.
• SCSI-2 adds features to the standard including, SCSI linking,
command queueing, and support for additional SCSI peripheral
devices. The SCSI-2 standard also includes the following:
• Fast SCSI is a SCSI data transfer standard that allows up to 10
megabytes per second data transfer on the SCSI bus.
• Wide SCSI provides data transfer at 16-bits for faster data
throughput. Up to 20 megabytes per second is supported on Fast and
Wide SCSI host adapters.
