Cheetah 9LP Product Manual, Rev. C Scope This manual describes Seagate Technology®, Inc. Cheetah 9LP™ disc drives. Cheetah 9LP drives support the small computer system interface (SCSI) as described in the ANSI SCSI, SCSI-2, and SCSI-3 (Fast-20 and Fast-40) interface specifications to the extent described in this manual. The SCSI Interface Product Manual (part number 77738479) describes general SCSI interface characteristics of this and other families of Seagate drives.
Mounting by bottom holes must meet the requirements of Section 8.4. Standards The Cheetah 9LP family complies with Seagate standards as noted in the appropriate sections of this Manual and the Seagate SCSI Interface Product Manual , part number 77738479 (Vol. 2).

Cheetah 9LP family of drives, and the SCSI Interface Product Manual (volume 2), part number 77738479, which describes the general interface characteristics of this and other families of Seagate SCSI drives. The drive’s interface supports multiple initiators, disconnect/reconnect, self-configuring host software, and automatic features that relieve the host from the necessity of knowing the physical characteristics of the targets (logical block addressing is used).
Cheetah 9LP Product Manual, Rev. C Standard features The Cheetah 9LP family has the following standard features: • Integrated Ultra/Ultra2 SCSI controller • Multimode SCSI drivers and receivers—single-ended (SE) and low voltage differential (LVD) • 16 bit I/O data bus •...
Cheetah 9LP Product Manual, Rev. C Unformatted and formatted capacities Formatted capacity depends on the number of spare reallocation sectors reserved and the number of bytes per sector.

Cheetah 9LP Product Manual, Rev. C number 77738479), data requested by the host with a Read command is retrieved from the buffer (if it is there), before any disc access is initiated. If cache operation is not enabled, the buffer (still segmented with required number of segments) is still used, but only as circular buffer segments during disc medium read operations (disregarding Prefetch operation for the moment).
Cheetah 9LP Product Manual, Rev. C The Synchronize Cache command may be used to force the drive to write all cached write data to the medium. Upon completion of a Synchronize Cache command, all data received from previous write commands will have been written to the medium.
Cheetah 9LP Product Manual, Rev. C Reliability specifications The following reliability specifications assume correct host/drive operational interface, including all interface timings, power supply voltages, environmental requirements and drive mounting constraints (see Section 8.4). Seek Errors Less than 10 in 10 seeks Read Error Rates [1] Recovered Data...
Cheetah 9LP Product Manual, Rev. C unrecoverable seek error. Unrecoverable seek errors are classified as failures for MTBF calculations. Refer to Section 5.1.1.2 of the SCSI Interface Product Manual, part number 77738479, for Request Sense information. Reliability and service You can enhance the reliability of Cheetah 9LP disc drives by ensuring that the drive receives adequate cool- ing.
Case 4 - Current I/O process allowed during insertion or removal, except on the device being changed Seagate Cheetah 9LP disc drives support all four hot plugging cases. Provision shall be made by the system such that a device being inserted makes power and ground connections prior to the connection of any device signal contact to the bus.
Cheetah 9LP Product Manual, Rev. C 5.2.8 S.M.A.R.T. S.M.A.R.T. is an acronym for Self-Monitoring Analysis and Reporting Technology. This technology is intended to recognize conditions that indicate a drive failure and is designed to provide sufficient warning of a failure to allow data back-up before an actual failure occurs.

There will not be any discrete tones more than 10 dB above the masking noise on typical drives when mea- sured according to Seagate specification 30553-001. There will not be any tones more than 24 dB above the masking noise on any drive.
Cheetah 9LP Product Manual, Rev. C Mechanical specifications The following nominal dimensions are exclusive of the decorative front panel accessory. However, dimensions of the front panel are shown in figure below. Refer to Figures 6 and 7 for detailed mounting configuration dimensions.
Cheetah 9LP Product Manual, Rev. C Notes: Mounting holes are 6-32 UNC 2B, three -Z- -X- on each side and four on the bottom. Max screw penetration into side of drive is 0.15 in. (3.81 mm). Max screw tightening torque is 6.0 in-lb (3.32 nm) with minimum full thread engagement of 0.12 in.
Cheetah 9LP Product Manual, Rev. C Defect and error management The drive, as delivered, complies with this specification. The read error rate and specified storage capacity are not dependent upon use of defect management routines by the host (initiator). Defect and error management in the SCSI system involves the drive internal defect/error management and SCSI systems error considerations (errors in communications between Initiator and the drive).

Spindle starts immediately after power up - Default setting.
Cheetah 9LP Product Manual, Rev. C Drive orientation The balanced rotary arm actuator design of the drive allows it to be mounted in any orientation. All drive perfor- mance characterization, however, has been done with the drive in horizontal (discs level) and vertical (drive on its side) orientations, and these are the two preferred mounting orientations.
(F) is applied to the fourth point. Note. Before mounting the drive in any kind of 3.5-inch to 5.25-inch adapter frame, verify with Seagate Tech- nology that the drive can meet the shock and vibration specifications given herein while mounted in such an adapter frame.
No attempt is made to describe all of the minute details of conditions and constraints that must be considered 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 , part number 77738479.

Cheetah 9LP Product Manual, Rev. C 9.6.2 SCSI interface physical description The drive models described by this product manual support the physical interface requirements of the SCSI-3 Parallel Interface-2 (SPI-2) standards as defined in American National Standard document X3T10/1142D revi- sion 14, and operate compatibly at the interface with devices that support earlier SCSI-2 and SCSI-3 stan- dards.
Cheetah 9LP Product Manual, Rev. C To minimize discontinuances and signal reflections, cables of different impedances should not be used in the same bus. Implementations may require trade-offs in shielding effectiveness, cable length, number of loads and spacing, transfer rates, and cost to achieve satisfactory system operation. If shielded and unshielded cables are mixed within the same SCSI bus, the effect of impedance mismatch must be carefully considered.
