General description
Cheetah NS FC drives provide high performance, high capacity data storage for a variety of systems including
engineering workstations, network servers, mainframes, and supercomputers. Cheetah NS FC drives support
4-Gbit Fibre Channel which can transfer data at up to 800 Mbytes per second and 1600 Mbytes per second in
dual-loop configurations.
engineering workstations, network servers, mainframes, and supercomputers. Cheetah NS FC drives support
4-Gbit Fibre Channel which can transfer data at up to 800 Mbytes per second and 1600 Mbytes per second in
dual-loop configurations.
Cheetah NS FC drives support the Fibre Channel Arbitrated Loop (FC-AL) and SCSI Fibre Channel Protocol
as described in the ANSI specifications, this document, and the Fibre Channel Interface Manual which
describes the general interface characteristics of this drive. Cheetah NS FC drives are classified as intelligent
peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard.

Note.
Never disassemble the HDA and do not attempt to service items in the sealed enclosure (heads,
media, actuator, etc.) as this requires special facilities. The drive does not contain user-replaceable
parts. Opening the HDA for any reason voids your warranty.

parts. Opening the HDA for any reason voids your warranty.
Cheetah drives use a dedicated landing zone at the innermost radius of the media to eliminate the possibility 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 discs 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.
