There is approximately a 1.5 increase in time to format a SED drive versus a non-SED drive of the same capacity. Execution time measured from receipt of the last byte of the Command Descriptor Block (CDB) to the request for a Status Byte Transfer to the Initiator (excluding connect/disconnect). -
Page 17: Prefetch/Multi-Segmented Cache Control
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 30 sec- onds (maximum) from removal of DC power. -
Page 18: Caching Write Data
5.5.1 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 19: 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 10 errors in 10 bits transferred (OEM default settings) -
Page 20: Seek Errors
6.1.3 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 21: S.m.a.r.t
6.2.4 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. Note. -
Page 22: Thermal Monitor
Reporting control Reporting is controlled by the MRIE bits in the Informational Exceptions Control mode page (1Ch). Subject to the reporting method, the firmware will issue to the host an 01-5Dxx sense code. The error code is preserved through bus resets and power cycles. Determining rate S.M.A.R.T. -

Page 44: Default Password
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: Power Requirements
2. The download file must be signed and authenticated. 3. As with a non-SED drive, the download file must pass the acceptance criteria for the drive. For example it must be applicable to the correct drive model, and have compatible revision and customer status. Power requirements The standard drive models and the SED drive models have identical hardware, however the security and encryption portion of the drive controller ASIC is enabled and functional in the SED models. -
Page 46: Defect And Error Management
10.0 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 47 Table 17 equates the read and write retry count with the maximum possible recovery time for read and write recovery of individual LBAs. The times given do not include time taken to perform reallocations. Reallocations are performed when the ARRE bit (for reads) or AWRE bit (for writes) is one, the RC bit is zero, and the recov- ery time limit for the command has not yet been met.

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 50: Installation
11.0 Installation Cheetah 15K.7 disk drive installation is a plug-and-play process. There are no jumpers, switches, or termina- tors 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. -
Page 51: Drive Mounting
If forced air is determined to be necessary, possible air-flow patterns are shown in Figure 11. The air-flow pat- terns are created by one or more fans, either forcing or drawing air as shown in the illustrations. Conduction, convection, or other forced air-flow patterns are acceptable as long as the temperature measurement guide- lines of Section 7.4.1 are met. -

Page 53: Dual Port Support
12.2 Dual port support Cheetah 15K.7 SAS drives have two independent ports. These ports may be connected in the same or differ- ent 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. - Page 54 Table 20: Commands supported by Cheetah 15K.7 SAS family drives (continued) Command name Command code Supported TSD bit ETC bit TMC bit LP bit Log Sense Application Client Log page (0Fh) Buffer Over-run/Under-run page (01h) Cache Statistics page (37h) Factory Log page (3Eh) Last n Deferred Errors or Asynchronous Events page (0Bh) Last n Error Events page (07h) Non-medium Error page (06h)
