  • Page 21: Prefetch/Multi-Segmented Cache Control

    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. There is no power control switch on the drive. 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.

  • Page 22: 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 23: 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 24: 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 25: Hot Plugging The Drive

    5.2.3 Hot plugging the drive When a disc is powered on by switching the power or hot plugged, the drive runs a self test before attempting to communicate on its’ interfaces. When the self test completes successfully, the drive initiates a Link Reset starting with OOB.

To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 8). Locate the typical I/O rate for a drive in your system on the horizontal axis and read the corresponding +5 volt current, +12 volt current, and total watts on the vertical axis.

  • Page 43: 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 44: 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 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 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: Sas System Errors

    SAS system errors Information on the reporting of operational errors or faults across the interface is given in the SAS Interface Manual. The SSP Response returns information to the host about numerous kinds of errors or faults. The Receive Diagnostic Results reports the results of diagnostic operations performed by the drive. Status returned by the drive to the initiator is described in the SAS Interface Manual.

  • Page 48: Deferred Auto-Reallocation

    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 49: Installation

    Installation Cheetah disc 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 disc 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 54: Dual Port Support

    Dual port support Cheetah 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 run at the same link rate. The first port to successfully complete speed negotiation sets the link rate support by both ports.
