ENERAL DESCRIPTION
Seagate
®
Enterprise Performance 10K HDD v7 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
interface is designed to meet next-generation computing demands for performance, scalability, flexibility and high-density
storage requirements.
interface is designed to meet next-generation computing demands for performance, scalability, flexibility and high-density
storage requirements.
Seagate Enterprise Performance 10K HDD drives are random access storage devices designed to 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. Seagate Enterprise Performance 10K HDD
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 interface 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 integrators to continue to leverage
existing investment in SCSI while gaining a 6Gb/s serial data transfer rate.

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 the warranty.

any reason voids the warranty.
Seagate Enterprise Performance 10K HDD drives use a dedicated load/unload zone at the outermost 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 ramp
load/unload 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.
