3.0General description

Cheetah 15K.5 FC drives provide high performance, high capacity data storage for a variety of systems includ- ing engineering workstations, network servers, mainframes, and supercomputers. Cheetah 15K.5 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 15K.5 FC drives support the Fibre Channel Arbitrated Loop (FC-AL) and SCSI Fibre Channel Proto- col as described in the ANSI specifications, this document, and the Fibre Channel Interface Manual which describes the general interface characteristics of this drive. Cheetah 15K.5 FC drives are classified as intelli- gent peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard.

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.5 FC 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 land- ing 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.
