3.0 General description Savvio drives combine Tunneling Magnetoresistive (TMR) heads and a Fibre Channel interface to provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers. Savvio drives also support 2-Gbit Fibre Channel which can transfer data at up to 200 Mbytes per second and 400 Mbytes per second in dual-loop configurations. Savvio 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. Savvio drives are classified as intelligent 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, actuator, etc.) as this requires special facilities. The drive does not contain user-replaceable parts. Opening the HDA for any reason voids your warranty. Savvio 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 during 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. 3.1 Standard features Savvio drives have the following standard features: • 2-Gbit Fibre Channel interface. For 2 gigabit operation, the block size must be divisable by 8. • Integrated dual port FC-AL controller • Concurrent dual port transfers • Support for FC arbitrated loop, private and public attachment • Differential copper FC drivers and receivers • Downloadable firmware using the FC-AL interface • Supports SCSI enclosure services via interface connector • 128-deep task set (queue) • Supports up to 32 initiators • Drive selection ID and configuration options are set on the FC-AL backpanel or through interface com- mands. Jumpers are not used on the drive. • Supports SCSI Enclosure Services through the interface connector • Fibre Channel worldwide name uniquely identifies the drive and each port Savvio FC Product Manual, Rev.

General description
Savvio drives combine Tunneling Magnetoresistive (TMR) heads and a Fibre Channel interface to provide high
performance, high capacity data storage for a variety of systems including engineering workstations, network
servers, mainframes, and supercomputers. Savvio drives also support 2-Gbit Fibre Channel which can transfer
data at up to 200 Mbytes per second and 400 Mbytes per second in dual-loop configurations.
Savvio 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. Savvio drives are classified as
intelligent 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.
Savvio 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.
