Benefits

FIGURE 1-1
library and four tape drives.
A small computer system interface also provides these benefits:
Low overhead
■
High transfer rates
■
A high-performance buffered interface
■
Conformance to industry standards
■
Plug compatibility for easy integration
■
Error recovery, parity, and sequence checking provides high reliability
■
Provisions in the command set for vendor-unique fields
■
Standard or common command sets with an intelligent interface that provides
■
device independence
The SCSI bus uses seven elements for interface control, data transfer, commands,
and status.

Implementation

Implementation of the SCSI bus for the library supports:
8-bit wide transfers, asynchronous; 16-bit wide selection
■
Disconnect and reselect
■
Multiple initiator
■
Hard resets
■
Single-ended LVD
■
SCSI-3, 68-pin P-cable
■
Implementation for the library does not support:
Soft resets
■
Command queuing
■
Command linking
■
Asynchronous event notification
■
Extended contingent allegiance
