Interface requirements
This section partially describes the interface requirements as implemented on the drives.
9.1
General description
This section describes in essentially general terms the interface requirements supported by the Cheetah 10K.7
SCSI. No attempt is made to describe all of the minute details of conditions and constraints that must be con-
sidered by designers when designing a system in which this family of drives can properly operate. Seagate
declares that the drives operate in accordance with the appropriate ANSI Standards referenced in various
places herein, with exceptions as noted herein or in the Seagate
SCSI Interface Product Manual
.
9.2
SCSI interface messages supported
Table 4 lists the messages supported by the SCSI-2 and SCSI-3 modes of the Cheetah 10K.7 SCSI family
drives.
