    General description Savvio drives combine Tunneling Magnetoresistive (TMR) heads and a Fibre Channel interface to provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers. Savvio drives also support 2-Gbit Fibre Channel which can transfer data at up to 200 Mbytes per second and 400 Mbytes per second in dual-loop configurations.

Seagate drives also may be used at the maximum available capacity at a given sector size, but the excess capacity above the guaranteed level will vary between other drive families and from generation to genera- tion, depending on how each sector size actually formats out for zone frequencies and splits over servo bursts.

  • 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

    Note. The size of each segment is not reported by Mode Sense command page 08h, bytes 14 and 15. The value 0XFFFF is always reported regardless of the actual size of the segment. Sending a size specification using the Mode Select command (bytes 14 and 15) does not set up a new segment size.

  • Page 21: Optimizing Cache Performance For Desktop And Server Applications

    decides that a prefetch hit will not likely occur. If the host is not using software interleave, and if two sequential read operations are not for contiguous blocks of data, ARLA disables prefetch, but as long as sequential read operations request contiguous blocks of data, ARLA keeps prefetch enabled. 4.5.3 Optimizing cache performance for desktop and server applications Desktop and server applications require different drive caching operations for optimal performance.

  • 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: S.m.a.r.t

    The disc drive defaults to the FC-AL Monitoring state, Pass-through state, when it is powered-on by switching the power or hot plugged. The control line to an optional port bypass circuit (external to the drive), defaults to the Enable Bypass state. If the bypass circuit is present, the next device in the loop will continue to receive the output of the previous device to the newly inserted device.

  • Page 26: Thermal Monitor

    Performance impact S.M.A.R.T. attribute data is saved to the disc so that the events that caused a predictive failure can be recre- ated. The drive measures and saves parameters once every two hours subject to an idle period on the FC-AL bus.

  • Page 27: Drive Self Test (Dst)

    If DST encounters an error during either of these tests, it reports a fault condition. If the drive fails the test, remove it from service and return it to Seagate for service. 5.2.6.1 DST failure definition The drive will present a “diagnostic failed”...

  • Page 41: 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 42: 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 The drive, as delivered, complies with this product manual. The read error rates and specified storage capaci- ties are not dependent upon use of defect management routines by the host (initiator). Defect and error management in the SCSI protocol involves the drive internal defect/error management and FC-AL system error considerations (errors in communications between the initiator and the drive).

  • Page 46: Fc-Al System Errors

    Table 4 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.

  • Page 47: Installation

    Installation Savvio disc drive installation is a plug-and-play process. There are no jumpers, switches, or terminators on the — drive. Simply plug the drive into the host’s 40-pin Fibre Channel backpanel connector (FC-SCA) no cables are required. See Section 9.5 for additional information about this connector. Use the FC-AL interface to select drive ID and all option configurations for devices on the loop.
