  • Page 10: General Description

    ENERAL DESCRIPTION Cheetah 15K.7 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 interface is designed to meet next-generation computing demands for performance, scalability, flexibility and high-density storage requirements. Cheetah 15K.7 drives support the Serial Attached SCSI Protocol as described in the ANSI specifications, this document, and the SAS Interface Manual (part number 100293071) which describes the general interface characteristics of this drive.

  • Page 11: Standard Features

    TANDARD FEATURES Cheetah 15K.7 drives have the following standard features: • 1.5 / 3 / 6 Gbit Serial Attached SCSI (SAS) interface • Integrated dual port SAS controller supporting the SCSI protocol • Support for SAS expanders and fanout adapters •...

  • Page 12: Reliability

    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 15: Cache Operation

    ACHE OPERATION Note. Refer to the SAS Interface Manual for more detail concerning the cache bits. Of the 16 Mbytes physical buffer space in the drive, approximately 13,000 kbytes can be used as a cache. The buffer is divided into logical segments from which data is read and to which data is written. The drive keeps track of the logical block addresses of the data stored in each segment of the buffer.

  • Page 16: 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 available for future read cache hits.

    5.2.1 Annualized Failrue Rate (AFR) and Mean time between failure (MTBF) These drives shall achieve an AFR of 0.55% (MTBF of 1,600,000 hours) when operated in an environment that ensures the HDA case temperatures do not exceed the values specified in Section 6.4. Operation at case temperatures outside the specifications in Section 6.4 may increase the AFR (decrease the MTBF).

  • Page 19: Thermal Monitor

    Performance impact S.M.A.R.T. attribute data is saved to the disk so that the events that caused a predictive failure can be recreated. The drive measures and saves parameters once every two hours subject to an idle period on the drive interfaces. The process of measuring off-line attribute data and saving data to the disk is uninterruptable.
