10.0Interface requirements
This section partially describes the interface requirements as implemented on the drives.
10.1General description
This section describes in essentially general terms the interface requirements supported by the Cheetah 15K.5 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 Parallel SCSI InterfaceManual and the SCSI Commands Reference Manual.
10.2SCSI interface messages supported
Table 7 lists the messages supported by the Cheetah 15K.5 SCSI family drives.
