    Constellation.2 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. The Self-Encrypting Drive Reference Manual, part number 100515636, describes the interface, general operation, and security features available on Self-Encrypting Drive models.

  • Page 15: General Description

    General description Constellation.2 drives provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers. The Serial Attached SCSI inter- face is designed to meet next-generation computing demands for performance, scalability, flexibility and high- density storage requirements.

  • Page 16: Standard Features

    Standard features Constellation.2 drives have the following standard features: • Perpendicular recording technology • 1.5 / 3 / 6 Gb Serial Attached SCSI (SAS) interface • Integrated dual port SAS controller supporting the SCSI protocol • Support for SAS expanders and fanout adapters •...

  • Page 17: Performance

    Seagate recommends product planning in one of two modes: 1. Seagate designs specify capacity points at certain block sizes that Seagate guarantees current and future products will meet. We recommend customers use this capacity in their project planning, as it ensures a stable operating point with backward and forward compatibility from generation to generation.

  • Page 21: 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 22: 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 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

    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 25: 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. 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.

  • Page 26: 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 27: 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 28 6.2.6.2.3 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 29: Product Warranty

    Shipping When transporting or shipping a drive, use only a Seagate-approved container. Keep your original box. Sea- gate approved containers are easily identified by the Seagate Approved Package label. Shipping a drive in a non-approved container voids the drive warranty.

  • Page 34: Conducted Noise Immunity

    General DC power requirement notes. 1. Minimum current loading for each supply voltage is not less than 1.7% of the maximum operating current shown. 2. The +5V and +12V supplies should employ separate ground returns. 3. Where power is provided to multiple drives from a common supply, careful consideration for individual drive power requirements should be noted.

    Three conditions must be met before the drive will allow the download operation: 1. The download must be an SED file. A standard (base) drive (non-SED) file will be rejected. 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.

  • Page 52: 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 53: Sas System Errors

    The drive firmware error recovery algorithms consist of 20 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 54: 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 56: Identifying A Protection Information Drive

    10.8.3 Identifying a Protection Information drive The Standard Inquiry provides a bit to indicate if PI is support by the drive. Vital Product Descriptor (VPD) page 0x86 provides bits to indicate the PI Types supported and which PI fields the drive supports checking. For further details with respect to PI, please refer to SCSI Block Commands - 3 (SBC-3) Draft Stan- Note.

  • Page 57: Installation

    11.0 Installation Constellation.2 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. In such systems, the host system typically provides a carrier or tray into which you need to mount the drive.

  • Page 58: Cooling

    11.2 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 7.5.1, "Temperature." The rack, cabinet, or drawer environment for the drive must provide heat removal from the electronics and head and disk assembly (HDA).

  • Page 59: Drive Mounting

    11.3 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).

    12.2 Dual port support Constellation.2 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 6Gb/s or the first port can run at 6Gb/s while the second port runs at 3Gb/s.
