The Host must issue a START UNIT command to cause the drive to spin up.

Mounting the Drive ------------------ The drive is designed to be used in applications where the unit may experience shock and vibrations at greater levels than larger and heavier disk drives will tolerate. The design features which allow greater shock tolerance are the use of rugged heads and media, a dedicated landing zone, closed loop servo positioning and specially designed motor and actuator assemblies. Eight side, or four bottom base mounting points are provided to the customer. The drive is mounted using 6-32 UNC -2B X 0.16 maximum insertion length screws. The system integrator should allow ventilation to the drive to ensure reliable drive operation over the operating temperature range. The drive may be mounted in any orientation. Cabling the Drive ----------------- The drive is intended for direct backplane connection to the SCA connector rather than through cabling. Attaching Power to the Drive ---------------------------- The drive is powered through the SCA connector and is intended for direct backplane connection rather than through cabling. External Terminator Power ------------------------- The interface connector carries both power and ground so a separate TERMPWR interface line is not provided. Internal Termination -------------------- This version of the drive has no on-board termination so the drive must be externally terminated. Alternative 2 active termination is recommended. Alternative 1 passive termination is not suitable for this application. Cable Requirements ------------------ This version of the drive is designed to interface directly a mating connector which is on a passive back plane or directly into a motherboard. The same guidelines relative to impedance, stub length and distance between stubs apply for SCSI bus signal reliability. These guidelines may not be directly translated to a back plane design so these design rules are to eb viewed with respect to the intended purpose of controlling reflections and the propagation of signals down the bus. Since the characteristics for PCB signal traces are affected by trace width, proximity to ground, and trace routing, careful review of the back plane design and analysis of signal quality is highly recommended. Connector Requirements ---------------------- The drive's connector will mate with a AMP Champ 2-557103-2 vertical receptacle or the AMP Champ 2-557101-1 right angle receptacle. Single Connector Attachment (SCA) Signal Definitions ---------------------------------------------------- Power Four +12 Volt signals provide the +12 volt power to the drive. The current return for the +12 volt power is through the +12 Volt Ground signals. The maximum current that can be provided to the drive through the +12 Volt signal pins is 3 Amperes. The supply current and return current must be distributed as evenly as possible among the pins. The maximum current is while the drive motor is starting. Three +5 Volt signal pins provide +5 volt power to the drive. The current return for the +5 volt power is through the +5 Volt Ground pins. It is expected that the +5 Volt Ground will also establish the digital logic ground for the drive. The maximum current that can be provided to the drive through the +5 Volt signal pins is 2 Amperes. The supply current and return current must be distributed as evenly as possible among the pins. Spindle Sync ------------ The spindle rotation of up to 35 drives may be synchronized together by daisy chaining pin 1 to pin 1 and pin 2 to pin 2 of each drive on connector J3. The spindles are synchronized using a "floating master" concept, where the drives will synchronize to the first drive to reach full speed. The synchronization tolerance is 1%. LED Out ------- The LED out signal is driven by the drive when the drive is perform- ing a SCSI operation. The LED out signal is designed to pull down the cathode of an LED. The anode is attached to the proper +5 volt supply through an appropriate current limiting resistor. The LED and the current limiting resistor are external to the drive. ********************************************************************** F E A T U R E S ********************************************************************** CONNER CFP-2107 PRODUCT MANUAL 501-071 6/94, PRE-RELEASE REV. A Overview of the Drives ---------------------- The CFP2107 series is a family of high performance 3.5-inch low- profile (1.0 inch high) 2.1GB (formatted) disk drives. They all offer 8.5 millisecond average seek time for Reading, 9.0 millisecond seek time for Writing, with an average latency of only 4.17ms. High capacity is achieved by utilizing a zone density recording technique using 15 recording zones at an areal density of 317 Mbits per square inch. These drives feature high performance while maintaining low power consumption to reduce power supply current and system cooling requirements in disk arrays. They are designed to operate on the Small Computer System Interface (SCSI) and are SCSI-2/3 command compatible. The mechanical and major electronic components are identical between the models and differ only in the host interface implementation. Firmware -------- The drive's firmware can be considered in two parts. The first part principally reside in the ROM for the 68HC16 background processor. This processor is responsible for: - starting the spindle motor and maintaining precise rotational speed - controlling track following and actuator motion during seeking - managing background R/W activity - power management - monitoring the overall health of the drive. The interface processor's control microcode resides in both ROM and RAM. The RAM portion of the microcode can be upgraded in the field with using software. The interface processor firmware functions include: - reporting drive status and error conditions to the host - manage operating parameters for the drive - parsing the Command Descriptor Block and checking for illegal fields - converting the LBA to CHS and initiating read and write operations to the background processor - defect management - serial port communications Since parsing/decoding of commands and execution of the Read/Write functions are handled by separate processors, command execution can be overlapped in multiple initiator or Tagged Command Queuing environments. Functions such as seek re-ordering and command coalesc- ing can also be overlapped when the drive is operating with a host environment capable of supporting Tagged Command Queuing.

For each 512-byte block, the on-the-fly error correction polynominal is capable of correcting: - one error burst of up to 41 bits in length - two error bursts each up to 17 bits in length The miscorrection probability is less than 1 bit in 10(24) bits transfered.
