Page 7: Scope
Exos 2X14 drives support the SAS Protocol specifications to the extent described in this manual. The SAS Interface Manual (part number 100293071) describes the general SAS characteristics of this and other Seagate SAS drives. Product data communicated in this manual is specific only to the model numbers listed in this manual. The data listed in this manual may not be predictive of future generation specifications or requirements. -

Page 9: General Description
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 Note manufacturer to ensure use of full capacity is supported. -

• Mean time between failures (MTBF) of 2,500,000 hours Media 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. Seagate Exos 2X14 SAS Product Manual, Rev. D... -
Page 11: Formatted Capacities
Standard OEM models are formatted to 4096 bytes per block for 4096 native drives. 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. -

Average rotational latency 4.16ms *Assumes no errors and no relocated logical blocks. Rate measured from the start of the first logical block transfer to or from the host. ** MiB/s x 1.048 = MB/s Seagate Exos 2X14 SAS Product Manual, Rev. D... -
Page 13: Start/Stop Time
The drive fetches the requested logical blocks from the disk and transfers them into a segment, and then from there to the host in accor- dance with the Mode Select Disconnect/Reconnect parameters, page 02h. If the prefetch feature is enabled, refer to section 4.4.2 for operation from this point. Seagate Exos 2X14 SAS Product Manual, Rev. D... -
Page 14: Caching Write Data
When prefetch (read look-ahead) is enabled (enabled by DRA = 0), the drive enables prefetch of contiguous blocks from the disk when it senses that a prefetch hit will likely occur. The drive disables prefetch when it decides that a prefetch hit is not likely to occur. Seagate Exos 2X14 SAS Product Manual, Rev. D... -
Page 15: Reliability Specifications
An interface error is defined as a failure of the receiver on a port to recover the data as transmitted by the device port connected to the receiver. The error may be detected as a running disparity error, illegal code, loss of word sync, or CRC error. Seagate Exos 2X14 SAS Product Manual, Rev. D... -
Page 16: Reliability And Service
Discharge the static electricity from the drive carrier prior to inserting it into the system. The drive motor must come to a complete stop prior to changing the Caution plane of operation. This time is required to insure data integrity. Seagate Exos 2X14 SAS Product Manual, Rev.

Shipping When transporting or shipping a drive, use only a Seagate-approved container. Keep the original box. Seagate approved containers are easily identified by the Seagate Approved Package label. Shipping a drive in a non-approved container voids the drive warranty. -

Seagate recommends that data centers be kept clean by monitoring and controlling the dust and gaseous contamination. Gaseous contamination should be within ANSI/ISA S71.04-2013 G2 classification levels (as measured on copper and silver coupons), and dust contamination to ISO 14644-1 Class 8 standards, and MTBF rated conditions as defined in the Annualized Failure Rate (AFR) and Mean Time Between Failure (MTBF) section. -

Page 32: Sas System Errors
This is in contrast to the system having to use the Reassign Command to reassign a location that was unreadable and then generate a write command to rewrite the data. DAR is most effective when AWRE and ARRE are enabled—this is the default setting from the Seagate factory. With AWRE and ARRE disabled DAR is unable to reallocate the failing location and will report an error sense code indicating that a write command is being attempted to a previously failing location. -
Page 33: Installation
The drive may be mounted in any orientation. All drive performance characterizations, however, have been done with the drive in horizontal (discs level) and vertical (drive on its side) orientations, which are the two preferred mounting orientations.
