SEAGATE ENTERPRISE CAPACITY 3.5 HDD V4 SAS PRODUCT MANUAL, REV. A 7
3.0 GENERAL DESCRIPTION
Enterprise Capacity 3.5 HDD v4 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.
Enterprise Capacity 3.5 HDD v4 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. Enterprise Capacity 3.5 HDD v4 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 users
to continue to leverage existing investment in SCSI while gaining a 12Gb/s serial data transfer rate.
The Self-Encrypting Drive models indicated on the cover of this product manual have provisions for “Security of Data at Rest” based on the
standards defined by the Trusted Computing Group
(see
www.trustedcomputinggroup.org).
The head and disk assembly (HDA) is sealed at the factory. Air recirculates within the HDA through a non-replaceable filter to maintain a
contamination-free HDA environment.
Enterprise Capacity 3.5 HDD v4 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.
Enterprise Capacity 3.5 HDD v4 drives decode track 0 location data from the servo data embedded on each surface to eliminate
mechanical transducer adjustments and related reliability concerns.
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.
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
product warranty.
NOTE
Seagate recommends validating the configuration with the selected HBA/RAID
controller manufacturer to ensure use of full capacity is supported.
