3.0General description

NL35 Series drives combine Tunneling Magnetoresistive (TMR) heads and a Fibre Channel interface to pro- vide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers.

NL35 Series 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 (part number 77767496) which describes the general interface characteristics of this drive. NL35 Series drives are classified as intelligent peripherals and provide level 2 conformance (highest level) with the ANSI SCSI 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 contains no parts replaceable by the user and opening the HDA for any reason voids your warranty.

NL35 Series drives use a dedicated landing zone at the innermost radius of the media to eliminate the possibil- ity of destroying or degrading data by landing in the data zone. The drive automatically goes to the landing zone when power is removed.

An automatic shipping lock prevents potential damage to the heads and discs that results from movement dur- ing shipping and handling. The shipping lock automatically disengages when power is applied to the drive and the head load process begins.

Ahigh-performance actuator assembly with a low-inertia, balanced, patented, straight arm design provides excellent performance with minimal power dissipation.
