Page 8: Scope
This manual describes Seagate® Exos™ 7E8 SAS (Serial Attached SCSI) disk drives. Seagate Exos 7E8 SAS 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. -
Page 9: Applicable Standards And Reference Documentation
Seagate drives are tested in representative end-user systems. Although CE-marked Seagate drives comply with all relevant regulatory requirements and standards for the drives, Seagate cannot guarantee that all system-level products into which the drives are installed comply with all regulatory requirements and standards applicable to the system-level products. -

Morocco Commodity Mark To satisfy our OEM customers, Seagate has added the Moroccan Commodity Mark to the drives provided to the OEM for the sale of Customer Kits produced by our OEM customers that are intended to be incorporated into the OEM's finished system-level product by an end user. -
Page 11: Environmental Protection
Restriction of Hazardous Substances in Electrical and Electronic Equipment Seagate drives are designed to be compliant with the European Union RoHS "Recast" Directive 2011/65/EU (RoHS 2) as amended by Directive (EU) 2015/863. The RoHS2 restricts the use of certain hazardous substances such as Lead, Cadmium, Mercury, Hexavalent Chromium, Polybrominated Biphenyls (PBB) and Polybrominated Diphenyl Ether (PBDE), BisBis(2-Ethylhexyl) phthalate (DEHP), Benzyl butyl phthalate (BBP), Dibutyl phthalate (DBP), and Diisobutyl phthalate (DIBP) in electrical and electronic equipment (EEE). -
Page 12: Taiwan Requirements - Taiwan Rohs
Taiwan RoHS refers to the Taiwan Bureau of Standards, Metrology and Inspection’s (BSMI) requirements in standard CNS 15663, Guidance to reduction of the restricted chemical substances in electrical and electronic equipment. Seagate products must comply with the “Marking of presence” requirements in Section 5 of CNS 15663, effective January 1, 2018. This product is Taiwan RoHS compliant. -
Page 13: General Description
Seagate Exos 7E8 SAS 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. -

Page 15: Formatted Capacities
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. -

Page 18: 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 7E8 SAS Product Manual, Rev.A... -
Page 19: 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 7E8 SAS Product Manual, Rev.A... -
Page 20: Reliability And Service
Reliability and service Users can enhance the reliability of Seagate Exos 7E8 SAS disk drives by ensuring that the drive receives adequate cooling. Section 6.0 provides temperature measurements and other information that may be used to enhance the service life of the drive. Section 10.2 provides recommended air-flow information. - Page 21 (not to exceed zero) whenever the error rate is acceptable.

Page 24: Product Warranty
See “Seagate® Technology Support Services” on page 6 for warranty contact information. 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. -

Page 40: Background Media Scan
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 41: Protection Information (Pi)
RDPROTECT and WRTPROTECT fields. The drive will generate 8 bytes (e.g.0xFFFF) 8 bytes of Protection Information to be stored on the media, but the 8 bytes will not be transferred to the host during a read command.

Page 42: 10.0 Installation
10.0 Installation Seagate Exos 7E8 SAS disk drive installation is a plug-and-play process. There are no jumpers, switches, or terminators on the drive. SAS drives are designed to be used in a host system that provides a SAS-compatible backplane with bays designed to accommodate the drive. In such systems, the host system typically provides a carrier or tray into which users need to mount the drive. -

Page 45: 11.0 Interface Requirements
11.2 Dual port support Seagate Exos 7E8 SAS SAS drives have two independent ports. These ports may be connected in the same or different SCSI domains. Each drive port has a unique SAS address. The two ports have the capability of independent port clocking (e.g. both ports can run at 12Gb/s or the first port can run at 6Gb/s while the second port runs at 3Gb/s.) The supported link rates are 3.0, 6.0, or 12.0 Gb/s. -
