General description

Cheetah 15K.6 drives provide high performance, high capacity data storage for a variety of systems including

engineering workstations, network servers, mainframes, and supercomputers. The Serial Attached SCSI inter-

face is designed to meet next-generation computing demands for performance, scalability, flexibility and high-

density storage requirements.

Cheetah 15K.6 drives support the Serial Attached SCSI Protocol as described in the ANSI specifications, this

document, and the SAS Interface Manual (part number 100293071) which describes the general interface

characteristics of this drive. Cheetah 15K.6 drives are classified as intelligent peripherals and provide level 2

conformance (highest level) with the ANSI SCSI-1 standard. The SAS connectors, cables and electrical inter-

face are compatible with Serial ATA (SATA), giving future users the choice of populating their systems with

either SAS or SATA hard disk drives. This allows you to continue to leverage your existing investment in SCSI

while gaining a 3Gb/s serial data transfer rate.

Cheetah 15K.6 SAS FDE models have provisions for "Security of Data at Rest" based on the standards

defined by the Trusted Computing Group (see www.trustedcomputinggroup.org).

Never disassemble the HDA and do not attempt to service items in the sealed enclosure (heads, media, actu-

ator, etc.) as this requires special facilities. The drive does not contain user-replaceable parts. Opening the

HDA for any reason voids your warranty.

Cheetah 15K.6 drives use a dedicated landing zone at the innermost radius of the media to eliminate the pos-

sibility of destroying or degrading data by landing in the data zone. The heads automatically go to the landing

zone when power is removed from the drive.

An automatic shipping lock prevents potential damage to the heads and disks that results from movement dur-

ing shipping and handling. The shipping lock disengages and the head load process begins when power is

applied to the drive.

The drives also use a high-performance actuator assembly with a low-inertia, balanced, patented, straight arm

design that provides excellent performance with minimal power dissipation.
