Page 19: Prefetch/Multi-Segmented Cache Control
Prefetch/multi-segmented cache control The drive provides a prefetch (read look-ahead) and multi-segmented cache control algorithms that in many cases can enhance system performance. Cache refers to the drive buffer storage space when it is used in cache operations. To select this feature, the host sends the Mode Select command with the proper values in the applicable bytes in page 08h. -
Page 20: Caching Write Data
4.5.1 Caching write data Write caching is a write operation by the drive that makes use of a drive buffer storage area where the data to be written to the medium is stored while the drive performs the Write command. If read caching is enabled (RCD=0), then data written to the medium is retained in the cache to be made avail- able for future read cache hits. -
Page 21: Reliability Specifications
Reliability specifications The following reliability specifications assume correct host and drive operational interface, including all inter- face timings, power supply voltages, environmental requirements and drive mounting constraints. Seek error rate: Less than 10 errors in 10 seeks Read Error Rates Recovered Data Less than 1 error in 10 bits transferred (OEM default settings) -
Page 22: Seek Errors
5.1.3 Seek errors A seek error is defined as a failure of the drive to position the heads to the addressed track. After detecting an initial seek error, the drive automatically performs an error recovery process. If the error recovery process fails, a seek positioning error (Error code = 15h or 02h) will be reported with a Hardware error (04h) in the Sense Key. -
Page 23: S.m.a.r.t
Caution. The drive motor must come to a complete stop prior to changing the plane of operation. This time is required to insure data integrity. 5.2.4 S.M.A.R.T. S.M.A.R.T. is an acronym for Self-Monitoring Analysis and Reporting Technology. This technology is intended to recognize conditions that indicate imminent drive failure and is designed to provide sufficient warning of a failure to allow you to back up the data before an actual failure occurs. -
Page 24: Thermal Monitor
S.M.A.R.T. measures error rates. All errors for each monitored attribute are recorded. A counter keeps track of the number of errors for the current interval. This counter is referred to as the Failure Counter. Error rate is the number of errors per operation. The algorithm that S.M.A.R.T. uses to record rates of error is to set thresholds for the number of errors and their interval. -
Page 25: Drive Self Test (Dst)
DST. It is the responsibility of the host application to determine the “not ready” cause. While not technically part of DST, a Not Ready condition also qualifies the drive to be returned to Seagate as a failed drive. - Page 26 5.2.6.2.3 Short and extended tests DST has two testing options: 1. short 2. extended These testing options are described in the following two subsections. Each test consists of three segments: an electrical test segment, a servo test segment, and a read/verify scan segment.

Page 39: Air Cleanliness
The sil- ver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic components should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%. -
Page 40: Acoustics
There will not be any discrete tones more than 10 dB above the masking noise on typical drives when mea- sured according to Seagate specification 30553-001. There will not be any tones more than 24 dB above the masking noise on any drive. -

Page 43: Locking Sp
7.2.2 Locking SP The Locking SP controls read/write access to the media and the cryptographic erase feature. Access to the Locking SP is available using the BandMasterX or EraseMaster passwords. Since the drive owner can define up to 16 data bands on the drive, each data band has its own password called BandMasterX where X is the number of the data band (0 through 15). -
Page 44: Cryptographic Erase
Authenticated firmware download In addition to providing a locking mechanism to prevent unwanted firmware download attempts, the drive also only accepts download files which have been cryptographically signed by the appropriate Seagate Design Center. Three conditions must be met before the drive will allow the download operation: 1. -
Page 45: Defect And Error Management
Defect and error management Seagate continues to use innovative technologies to manage defects and errors. These technologies are designed to increase data integrity, perform drive self-maintenance, and validate proper drive operation. SCSI defect and error management involves drive internal defect/error management and SAS system error considerations (errors in communications between the initiator and the drive). -
Page 46: Sas System Errors
The drive firmware error recovery algorithms consists of 11 levels for read recoveries and five levels for write. Each level may consist of multiple steps, where a step is defined as a recovery function involving a single re- read or re-write attempt. The maximum level used by the drive in LBA recovery is determined by the read and write retry counts. -
Page 47: Background Media Scan
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 48: Idle Read After Write
Idle Read After Write Idle Read After Write (IRAW) utilizes idle time to verify the integrity of recently written data. During idle periods, no active system requests, the drive reads recently written data from the media and compares it to valid write command data resident in the drives data buffer. -
Page 49: Installation
Installation Savvio 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 you need to mount the drive. -
Page 50: Cooling
Cooling Cabinet cooling must be designed by the customer so that the ambient temperature immediately surrounding the drive will not exceed temperature conditions specified in Section 6.4.1, "Temperature." The rack, cabinet, or drawer environment for the drive must provide heat removal from the electronics and head and disk assembly (HDA). -
Page 51: Drive Mounting
Drive mounting Mount the drive using the bottom or side mounting holes. If you mount the drive using the bottom holes, ensure that you do not physically distort the drive by attempting to mount it on a stiff, non-flat surface. The allowable mounting surface stiffness is 80 lb/in (14.0 N/mm). -
Page 52: Interface Requirements
10.0 Interface requirements This section partially describes the interface requirements as implemented on Savvio drives. Additional infor- mation is provided in the SAS Interface Manual (part number 100293071). 10.1 SAS features This section lists the SAS-specific features supported by Savvio drives. 10.1.1 Task management functions Table 5 lists the SAS task management functions supported. -
Page 53: Dual Port Support
10.2 Dual port support Savvio 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 6Gbit/sec or the first port can run at 6Gbit/sec while the second port runs at 3Gbit/sec.) The supported link rates are 1.5, 3.0, or 6.0 Gbits/sec. -
