Preface
This manual contains information for users of the Seagate® Cheetah 9 SCSI disc drives. It provides support services, perfor- mance specifications, and initial setup information. Additional information is available in the Cheetah 9 Product Manual (part number 83329170). Contact your Seagate sales representative if you need to order this publication.
Attention. This high performance Cheetah disc drive MUST have proper power and cooling considerations for reliable operation.
Why is there a difference between 10,000 RPM and 7,200 RPM disc drives?
•Cheetah disc drives spinning at 10,000 RPM will dissipate more heat than 7,200 RPM class disc drives (typical power dissipation is 22.5 watts).
•The increased heat is primarily due to increased motor power dissipated inside the drive.
•The increase in heat dissipation requires that the Cheetah 10,000 RPM disc drives receive more cooling consideration than 7,200 RPM class disc drives.
•Proper consideration of enhanced cooling by conduction (heat transfer thru material) can reduce the convection cooling (heat transfer by air motion) requirements.
Note. Please contact Seagate technical support services or your distributor’s technical support if you have questions.
