3.0General description
Exos X16 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 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.trustedcomputin
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.
Note
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 userreplaceable parts. Opening the HDA for any reason voids the product warranty.
Seagate recommends validating the configuration with the selected HBA/RAID controller
manufacturer to ensure use of full capacity is supported.

3.4Media description
The media used on the drive has a glass substrate coated with a thin film magnetic material, overcoated with a proprietary protective layer for
improved durability and environmental protection.
3.5Formatted capacities
Standard OEM models are formatted to 512 bytes per block for 512 emulation drives and 4096 bytes per block for 4096 native drives. The block
size is selectable at format time. Supported block sizes are 512, 520 and 528 for 512 emulation drives and 4096, 4160 and 4224 for 4096 native
drives. Users having the necessary equipment may modify the data block size before issuing a format command and obtain different formatted
capacities than those listed.
To provide a stable target capacity environment and at the same time provide users with flexibility if they choose, Seagate recommends product
planning in one of two modes:
Seagate designs specify capacity points at certain block sizes that Seagate guarantees current and future products will meet. We recommend
customers use this capacity in their project planning, as it ensures a stable operating point with backward and forward compatibility from
generation to generation. The current guaranteed operating points for this product are shown below.

12TB with PI bytes12TB w/o PI bytes10TB with PI bytes10TB w/o PI bytes
DecimalHexDecimalHexDecimalHexDecimalHex
LBA Counts for drive capacities greater than 8TB are calculated based upon
the SFF-8447 standard publication. ftp://ftp.seagate.com/sff/SFF-8447.PDF
3.6Programmable drive capacity
Using the Mode Select command, the drive can change its capacity to something less than maximum. See the Mode Select (6) parameter list table
in the SAS Interface Manual, part number 100293071. A value of zero in the Number of Blocks field indicates that the drive will not change the
capacity it is currently formatted to have. A number other than zero and less than the maximum number of LBAs in the Number of Blocks field
changes the total drive capacity to the value in the Number of Blocks field. A value greater than the maximum number of LBAs is rounded down to
the maximum capacity.
3.7Factory-installed options
Users may order the following items which are incorporated at the manufacturing facility during production or packaged before shipping. Some
of the options available are (not an exhaustive list of possible options):
• Other capacities can be ordered depending on sparing scheme and sector size requested.
• Single-unit shipping pack. The drive is normally shipped in bulk packaging to provide maximum protection against transit damage. Units
shipped individually require additional protection as provided by the single unit shipping pack. Users planning single unit distribution should
specify this option.
•The Safety and Regulatory Agency Specifications, part number 75789512, is usually included with each standard OEM drive shipped, but extra
copies may be ordered.

The drive accepts the commands listed in the SAS Interface Manual less than 3 seconds after DC power has been applied.
If the drive receives a NOTIFY (ENABLE SPINUP) primitive through either port and has not received a START STOP UNIT command with the START
bit equal to 0, the drive becomes ready for normal operations within 30 seconds (excluding the error recovery procedure).
If the drive receives a START STOP UNIT command with the START bit equal to 0 before receiving a NOTIFY (ENABLE SPINUP) primitive, the drive
waits for a START STOP UNIT command with the START bit equal to 1. After receiving a START STOP UNIT command with the START bit equal to 1,
the drive waits for a NOTIFY (ENABLE SPINUP) primitive. After receiving a NOTIFY (ENABLE SPINUP) primitive through either port, the drive
becomes ready for normal operations within 30 seconds (excluding the error recovery procedure).
If the drive receives a START STOP UNIT command with the START bit and IMMED bit equal to 1 and does not receive a NOTIFY (ENABLE SPINUP)
primitive within 5 seconds, the drive fails the START STOP UNIT command.
The START STOP UNIT command may be used to command the drive to stop the spindle. Stop time is 23 seconds (maximum) from removal of DC
power. SCSI stop time is 23 seconds. There is no power control switch on the drive.
