General description

Exos X16 drives provide high per formance, high capacity data storage for a variety of systems including engineering workstations, network

servers, mainframes, and supercomputers. The Serial Attached SCSI inter face is designed to meet next-generation computing demands for 
performance, scalability, flexibility and high-density storage requirements.

Exos X16 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 X16 

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. Helium recirculates within the HDA through a non-replaceable filter to maintain a

contamination-free HDA environment.

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 X16 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.
