(0.45 Kg) 1.5 Seek time All seek time measurements are taken under nominal conditions of temperature and voltage with the drive mounted horizontally. In the following table: • Track-to-track seek time is the average of all possible single-track seeks in both directions.
Medalist Pro 2160N/ 2160WC Product Manual, Rev. A 1.6 7 Read look-ahead and caching The drives use algorithims that improve seek performance by storing data in a buffer and processing it at a more convenient time. Three methods are used: read look-ahead, read caching and write caching. These are described in Appendix C.6 on page 108. 1.7 Start/stop command If the motor-start option is disabled, the drive is ready within 20 seconds after power is applied.
8 Medalist Pro 2160N/ 2160WC Product Manual, Rev. A 3. Within 250 msec after power is applied, the drive responds to the Test Unit Ready, Request Sense, Mode Sense and Inquiry commands. 4. The drive begins to lock in speed-control circuits. 6. The actuator lock releases the actuator. 7. The spindle motor reaches operating speed in about 5 seconds. After 5 seconds, there are no speed variations. 8. The drive performs velocity-adjustment seeks. 9. The drive seeks track 0 and is then ready. 1.7.
Medalist Pro 2160N/ 2160WC Product Manual, Rev. A 9 • Seek. The servo electronics are active, and the heads are moving to a specific location on the disc. The read/write electronics are powereddown. The power consumed in this mode is equivalent to the average power measured while executing random seeks with a 2-revolution (26.6 msec) dwell between seeks. The drive enters this mode from the Idle mode. • Read/Write. The drive is reading or writing. All electronics are active and the heads are on track.

Medalist Pro 2160N/2160WC Product Manual, Rev. A 17 2.0 Hardware and interface The Medalist Pro drives use an UltraSCSI interface. The ST52160N consists of an 8-bit bidirectional data bus. The ST52160WC consists of a 16-bit bidirectional data bus. The interface supports multiple initiators, disconnect and reconnect, self-configuring host software and logical block addressing.
18 Medalist Pro 2160N/2160WC Product Manual, Rev. A • Always rest the drive on a padded, antistatic surface until you mount it in the host system. • Do not touch the connector pins or the printed circuit board. • Do not remove the factory-installed labels from the drive or cover them with additional labels. If you do, you void the warranty. Some factoryinstalled labels contain information needed to service the drive. Others are used to seal out dirt and contamination. 2.

20 2.5 Medalist Pro 2160N/2160WC Product Manual, Rev. A ST52160N interface connector The ST52160N uses a standard 50-pin, nonshielded, keyed connector. The connector consists of two rows of 25 male contacts 0.100 inches apart. Pin 1 on the connector is shown in Figure 3 on page 19. Recommended mating connectors and their part numbers are listed below. Part numbers for mating 3M connectors that are compatible with the drives are listed below.
Medalist Pro 2160N/2160WC Product Manual, Rev. A 2.5.1 21 ST52160N interface pin assignments The table below shows the pin assignment for the ST52160N 50-pin interface connector. A minus sign (−) indicates an active-low signal.
22 Medalist Pro 2160N/2160WC Product Manual, Rev. A 2.5.2 ST52160WC interface connector The ST52160WC uses an 80-pin blindmate single-connector attachment (SCA-2). It is a single-piece connector that provides power to the drive through the SCSI bus. The remote LED, motor start options and additional binary codes are also placed on the SCSI bus. Pin 1 on the connector is shown in Figure 3 on page 19. We recommend the AMP blindmate receptacle assembly (part number 787311-1). 2.5.

Medalist Pro 2160N/2160WC Product Manual, Rev. A 2.6 25 Interface cable requirements A characteristic impedance of 100 ohms + 10% is recommended for the unshielded flat or twisted-pair interface cable. However, most available cables have a somewhat lower characteristic impedance. To minimize discontinuities and signal reflections, do not use cables of different impedances on the same bus.
26 Medalist Pro 2160N/2160WC Product Manual, Rev. A • The maximum cable length when using 5 to 8 devices cannot be longer than 1.5 meters. • Cable stubs cannot be more than 0.1 meter long and must be separated by at least 0.3 meter. 2.7 Options jumper block The ST52160N and ST52160WC options jumper block allows you to: • Set the SCSI ID address. • Enable or disable active termination. • Enable parity. • Activate the motor start/stop option. • Attach a remote LED.

Medalist Pro 2160N/2160WC Product Manual, Rev. A 2.8 29 Active Termination Active termination is configured on the ST52160N using pins 11 and 12 on the J5 options jumper block. Active termination is enabled when there is no jumper on pins 11 and 12. Active termination is disabled when a jumper is placed on pins 11 and 12. The drive provides termination power to the drive’s terminator chips and to the SCSI bus. No other option is available. Termination is not provided on the ST52160WC.
30 Medalist Pro 2160N/2160WC Product Manual, Rev. A Devices at both ends of the SCSI bus must be terminated; intermediate devices should not be terminated. All electrical signals are common between all SCSI devices. 2.11 Hot-plugging Hot-plugging allows you to connect and disconnect the I/O and power cables for each SCSI device in a daisy chain without powering down the system.
Medalist Pro 2160N/2160WC Product Manual, Rev. A 31 Caution. To avoid damaging the drive: • Use only mounting screws of the type specified. • Gently tighten the mounting screws—do not apply more than 6 inch-lb of torque.

Medalist Pro 2160N/2160WC Product Manual, Rev. A 35 3.0 Command set The drives support a subset of the Group 0, Group 1 and Group 2 standard SCSI commands. The commands are described in this section. 3.1 Command descriptor block The initiator makes a request to the drive by sending a command descriptor block (CDB) to the drive. Each CDB has the following common characteristics: • Byte 0 always contains the operation code.
36 Medalist Pro 2160N/2160WC Product Manual, Rev. A 18H Reservation conflict status. A SCSI device tried to access the drive, but was unable to because the drive was already reserved by another SCSI device. 28H Queue full status. The drive received a command but rejected it because the queue was full. The drive only uses this status if tagged command queuing is implemented. 3.3 Supported commands The drive supports the commands listed below.

However, the drive always formats the disc with an interleave of 1:1. Defect lists When the Format Unit command is issued, media defect information can be gathered from several sources. Four of these sources—primary defect list, certification defect list, data defect list and grown defect list—are defect lists written to the drive. They are defined below.

Medalist Pro 2160N/2160WC Product Manual, Rev. A 3.4.6 45 Read (6) command (08H) When the drive receives the Read command, it transfers data to the initiator. The Read-Write Error Recovery page (01H) determines how the drive handles errors during a Read command. The Read-Write Error Recovery page is discussed in Appendix C.1 on page 98. If there is a reservation access conflict, this command terminates with a reservation conflict status and no data is read.
46 Medalist Pro 2160N/2160WC Product Manual, Rev. A 3.4.7 Write (6) command (0AH) When the drive receives the Write command, it writes the initiator’s data to the disc. The Read-Write Error Recovery page (01H) determines how the drive handles bad sectors during a Write command. The Read-Write Error Recovery page is discussed in Appendix C.1 on page 98. If the system supports disconnection, the drive can disconnect and reconnect while executing this command.
Medalist Pro 2160N/2160WC Product Manual, Rev. A 3.4.8 47 Seek (6) command (0BH) When the drive receives the Seek command, it seeks to the track of the specified logical block address. This command is not necessary because all commands that access the disc contain implied seeks. In systems that support disconnection, the drive disconnects when it receives a valid Seek command. Note. The Seek (6) command cannot access all logical blocks on the drive.
