  • Page 31: Space Requirements

    Installation SPACE REQUIREMENTS The Maxtor Atlas 15K hard disk drive is shipped without a faceplate and comes in the following SCSI interface configurations: • 68-pin Wide SCSI • 80-pin SCA-2 SCSI Figure 3-1 shows the mechanical dimensions of each of the drives.

  • Page 32: Shock Feet

    3.2.1 Shock Feet Maxtor Atlas 15K hard disk drives are outfitted with plastic shock feet on the bottom edge of the base casting, near the corners, beneath the side mounting holes (translucent), and near the corners of the top cover next to the screws (black). The shock feet give an additional level of isolation to prevent the head and disk damage that occasionally occurs during unpacking, staging, and installation.

    FORMATTED CAPACITY At the factory, the Maxtor Atlas 15K receives a low-level format that creates the actual tracks and sectors on the drive. Table 4-2 shows the capacity resulting from this process. Formatting done at the user level for operation with DOS, UNIX, or other operating systems, will result in less capacity than the physical capacity shown.

    Chapter 6 FEATURE DESCRIPTIONS This chapter provides descriptions of many of the features incorporated in the Maxtor Atlas 15K hard disk drive family. KEY FEATURES Maxtor Atlas 15K disk drives provide unequaled quality and performance. They are designed to improve the performance of high-end workstations, file servers, and storage systems.

  • Page 218: Prefetch

    This process, called prefetch, gives the drive a very high cache hit rate for sequential reads. Maxtor Atlas 15K...

  • Page 219: Write-Back Caching

    This minimizes rotational latency (and increases throughput) when data is accessed sequentially. Maxtor Atlas 15K...

  • Page 220: Average Access Time

    The hardware does not allow a blind read of a data block; the firmware must request specific data blocks. Even if the head selection hardware malfunctions, it is not possible for the drive to return data from the wrong head. Maxtor Atlas 15K...

  • Page 221: Data Sector Reallocation Error Protection

    The performance improvement is significant in heavily loaded applications where queue depth exceeds 10-15 commands. Maxtor Atlas 15K...

  • Page 222: Banded Recording

    6.13 POWER MANAGEMENT The Maxtor Atlas 15K hard disk drives have three basic power states: • OFF - power is removed from the drive. • UNIT READY - the drive is powered on and is ready to accept and execute commands.

  • Page 223: Power On Self Test (Post)

    The Host Processor can command the drive to perform diagnostic tests and report status using RECEIVE and SEND DIAGNOSTIC RESULTS commands. Certain parameters can be sent to the drive to alter or enhance the performance of the diagnostic tests specified. Maxtor Atlas 15K...

  • Page 224: Log Sense

    Feature Descriptions 6.14.4 Log Sense Maxtor implements multiple LOG SENSE pages which logically group together parameters related to disk and subsystem activities. Monitoring this data enables users to observe drive performance and possibly predict failures. 6.15 ERROR RECOVERY The mode pages control all error recovery. Any error recovery that is enabled is attempted without host intervention.

    320 MB/second. It is fully compatible with Ultra2 LVD devices operating at slower transfer rates. If an Maxtor Atlas 15K disk drive is installed on a bus with one or more single-ended (SE) devices, it automatically switches modes to operate in SE mode at the slower, legacy data rates.

  • Page 226: Diffsens

    HVD devices pull DIFFSENS up to +5 volts via a resistor. The Maxtor Atlas 15K disk drive is designed with a circuit that monitors the level of DIFFSENS at power-on. The drive then enables the appropriate circuits for LVD or single-ended operation, or disables its interface completely if it detects an HVD level on DIFFSENS.

  • Page 227: Dt And St Clocking

    ST clocking. Figure 6-1 ST and DT CLocking The Maxtor Atlas 15K disk drive can operate at speeds up to 80 MB/sec in either ST or DT modes, depending on the capabilities of the host adapter. Transfer rates above 80 MB/sec are only supported in DT mode, as required by the SPI-3 SCSI standard.

    CRC with its own. If the two CRC characters match, then the data burst transferred without error. In ST mode, the Maxtor Atlas 15K uses the traditional parity checking method to ensure error free data transfers.
