Exos 2X14 enterprise dual-actuator hard drives utilize MACH.2
3.5-inch hard drive. MACH.2TM technology increases performance in a single hard drive by using two independent actuators that can transfer
data to the host computer concurrently. 14TB of capacity is presented to the host system as two independently addressable 7TB logical units,
allowing the user to increase performance while effectively using the full capacity of the drive. Exos 2X14 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.
Exos 2X14 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. Exos
2X14 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 head and disk assembly (HDA) is sealed at the factory. Helium recirculates within the HDA through a non-replaceable filter to maintain a
contamination-free HDA environment.
Never disassemble the HDA and do not attempt to service items in the sealed enclosure
Note
(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.
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.
Exos 2X14 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.
Seagate recommends validating the configuration with the selected HBA/RAID controller

manufacturer to ensure use of full capacity is supported.
