Spindle Synchronization ----------------------- The Rotational Position Locking field (MODE SELECT command, Page Code 04h) is used to specify spindle synchronization operation. Unsynchronized: If the drive is set to Unsynchronized (RPL = 00b), it ignores the SLAVE SYNC signal. Slave: If the drive is set to Slave (RPL = 01b), it does not generate the MASTER SYNC signal or the SLAVE SYNC signal but synchronizes its index to the SLAVE SYNC signal supplied by an external source. Master: If the drive is set to Master (RPL = 10b), it generates the SLAVE SYNC output signal for use directly by the slave drives. Master Control: If the drive is set to Master Control (RPL = 11b), it generates the MASTER SYNC signal. This output is used by the controller to generate the SLAVE SYNC signal for the slaves. ********************************************************************** I N S T A L L ********************************************************************** MICROPL. 3221 PRELIMINARY PRODUCT DESCRIPTION 138008 REV. 1 Notes on installation ===================== Recommended mounting orientation -------------------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | | +-----+ +-----+ | +--+ +--+ Dimensions and Mounting ----------------------- The drive uses industry-standard mounting For 3 1/2-inch full-height Winchester disk drives. Recommended orientation is vertical on either side, or horizontal with the Device Electronics board down; other mounting orientations may be used. No matter what mounting orientation is used, Micropolis specifies that the maximum HDA casting temperature not exceed 60*C (140*F). Mounting Screws --------------- 3 per side 6-32 UNC-2B 4 on bottom 6-32 UNC-2B Caution: The mounting screws must be selected so that they do not penetrate the bottom mounting holes by more than 0.20 inches or the side mounting holes by more than 0.156 inches. Screws that are too long will short to PCBA. SINGLE-ENDED Interface Electrical Characteristics ------------------------------------------------- Interface control and status signals are digital (open collector TTL) using industry-standard transmitters and receivers which provide a terminated, single-ended system. For active termination, the assigned signals are terminated with 110 ohms to +2.85V (nominal). For passive termination, the assigned signals are terminated with 220 ohms to +5V (nominal) and 330 ohms to ground. All signals use open-collector or tri-state drivers. Single-ended drivers and receivers allow a maximum cable length of six meters (primarily for connection within a cabinet). Signal transmission requires a single 50-conductor (flat or twisted-pair) cable. A characteristic impedance of 100 ( 10%) ohms is recommended. a. Input Characteristics Each of the drive's signal receivers has the following characteristics when measured at the interface connector. 1) Low-level input voltage = (Signal true) 0.0 VDC to 0.8 VDC 2) High-level input voltage = (Signal false) 2.0 VDC to 5.25 VDC 3) Low-level input current = -0.4 milliamps at 0.5 VDC 4) High-level input current = 0.1 milliamps at 2.7 VDC 5) Minimum input hysteresis = 0.2 VDC 6) Maximum input capacitance = 25 pF b. Output Characteristics Each driven signal has the following characteristics when measured at the interface connector. 1) Low-level input voltage = 0.0 VDC to 0.5 VDC (signal assertion) 2) High-level input voltage = 2.5 VDC to 5.25 VDC (signal negation) 3) Minimum driver output capability = 48 milliamps (sink) at 0.5VDC c. Terminator Power (TERMPWR at Pin 26) Terminator Power has the following requirements: V(TERM) = 4.25 VDC to 5.25 VDC 800 milliamps minimum source drive capability, with 1.0 amp recommended current limiting (e.g., a fuse). 1.0-milliamp maximum bus loading (except for the purposes of providing power to an internal terminator). Keyed connectors are provided to prevent accidental grounding or misconnection of terminator power. Signal Connector J1 ------------------- J1 is a 50-pin connector. The signals on J1 include the 8-bit SCSI bus and various control and handshaking lines. Recommended Cable: 3M Scotchflex 3365/50 or equivalent. Mating connector: 3M P/N 3425-3000 or equivalent. J1A Power Connector ------------------- J1A is a 4-pin connector used to supply +5V and +12V to the drive. Recommended mating connector: AMP 1-480424-0 or equivalent Pins: AMP 350078-4 Suggested wire size: 18 AWG (minimum) for all pins. pin 1 +12 VDC pin 2 +12 Volts Return pin 3 + 5 Volts Return pin 4 + 5 VDC 2-pin Connectors (Remote LED, Spindle Sync, etc.) ------------------------------------------------- Recommended mating connectors: Dupont 69305-002 or equivalent Pins: Dupont 77138-001 Suggested wire size: 26-30 AWG for all pins SCSI ID Connector (6-pin) ------------------------- Recommended mating connector: Dupont 90311-006 or equivalent Pins: Dupont 77138-001 Suggested wire size: 26-30 AWG for all pins Multiple-Drive Systems ---------------------- Drive #1 +------HOST------+ +-----------------+ | +-----------+ +--+-SCSI-BUS-----+ J1 | | |Terminators| | | +------+ J1A | | +-----------+ | | | +-----------------+ | | | | +----------------+ | | Drive #2 | | +-----------------+ +-------+------+ J1 | | o------+ J1A | | | +-----------------+ | | | | Drive #3 | | +-----------------+ +-------+------+ J1 | | o------+ J1A | | | +-----------------+ | | | | Drive #4 | | +--------------+--+ +-------+------+ J1 |T | o------+ J1A +--+ ---DC-VOLTAGES-----+ +-----------------+ T = TERMINATORS Terminators are installed ONLY in the last physical drive in the control chain. Temperature Measurement ----------------------- Micropolis specifies the maximum HDA casting temperature to be 60*C (140*F). Not exceeding this temperature will ensure that the head-to- media interface never exceeds its temperature limit. If the HDA casting temperature measurement cannot be made, the ambient air temperature around the drive must be kept at or below 50*C (122*F). ********************************************************************** F E A T U R E S ********************************************************************** MICROPL. 3221 PRELIMINARY PRODUCT DESCRIPTION 138008 REV. 1 Description ----------- This Product Description describes the Micropolis model 3221 (8-bit, single-ended) Rigid Disk Drive. The drive is a member of the CAPRICORN family of high-performance, 3 1/2-inch, full-height Rigid Disk Drives. These drive provides OEMs with random-access, high-speed, data storage and meet the needs of diverse applications environments. The drive is compatible with the "ANSI CCS" version and the "SCSI-2" version of the industry-standard Small Computer System Interface (SCSI) specification. 3221 AV ------- The 3221 is available in an AV version. AV drives are specifically designed for enhanced digital audio and video performance in applications such as multi-media, desktop publishing, digital video editing, and video servers. AV drives provide: - Predictable, sustained data rates, allowing reduction in size of system buffers needed thereby reducing system cost. - Fast command processing for reduced overhead. - Advanced cache management for improved overall performance. - Fast ECC which ensures maximum data integrity without interrupting the data stream. DIFFERENTIAL INTERFACE IS OPTIONAL. Some Features of the Drive -------------------------- - Positive media protection is achieved during spin down (due to a STOP UNIT command or power off) by automatically retracting and locking the positioner in a data-free landing zone. - N-Segment Read-Ahead algorithm improves read performance by allowing many accesses to be serviced from the cache buffer (512K or optional 2MB). - Optional, Write-Behind Caching provides dramatic improvement in write performance by appending multiple write commands per disk revolution. - In-Line Defect Management (sector slipping) provides maximum throughput. - Data Integrity is ensured with CRC through the buffer, 126-bit Reed-Solomon ECC on-the-fly, and automatic retries using servo and data strobe offsets. Media Defects ------------- Media defects are physical characteristics of the media which result in repetitive read errors when a functional drive is operated within specified operating conditions. At the time of manufacture, a media test system evaluates every drive and identifies each media defect location. The defective areas are identified by head address (HD), cylinder address (CYL), and number of clocks from Index (CFI). The list of manufacturer-found defects is stored on the drive in a reserved, write-protected area accessible by the SCSI controller. This list is known as the MDL (Manufacturers Defect List) or PList (Primary Defect List). A printed listing of the defects is also shipped with each drive. The entries it contains can be mapped out (reassigned) automatically at format control parameter bits. Seek Time --------- | 3221 | ----------------------------------+--------+ Track-to-Track read msec. typ. | 1 | write msec. typ. | 2 | Average msec. typ. | 8.9 | msec. max. | 20 | Latency msec. avg. | 4.17 | ----------------------------------+--------+ Recording Media --------------- Aluminium disks, each 95 millimeters (3 1/2 inches) in diameter, are mounted on the spindle assembly. The recording surface on each disk is a thin coating of magnetic material, with a carbon over-coat to protect that surface. Air Filtration System --------------------- The drives are designed to provide contamination control within the HDA throughout the life of the drive with zero maintenance. Air within the HDA is continuously recirculated and filtered through a high efficiency filter. Air is ducted to and from the filter for maximum pressure recovery and filter efficiency. Air within the HDA may only enter the drive through a high-efficiency breather filter. Braking ------- The heads contact an area of the disk surface which is not used for data storage when the disk are not spinning and during start and stop cycles. Dynamic braking is used to stop the spindle quickly. Adjustments and Maintenance --------------------------- The drive requires no adjustments or periodic maintenance; additionally, no mechanical adjustments are required to prepare a system for handling or shipment. Field-Replaceable Components ---------------------------- The concept of repair by replacement of complete functional components is utilized in the drive, resulting in an MTTR of less than 15 minutes. MICROPOLIS AV SERIES -------------------- Micropolis AV Series disk drives are engineered specifically for multi-media, high-end graphics, and digital video/audio applications. With advanced cache management, internal housekeeping improvements, and enhanced error handling, AV drives provide the highest minimum sustained data rate in their class. AV drives are designed to provide a maximum sustained uninterrupted data rate. Unlike data processing drives, AV drives guarantee a "worst case" data rate performance. This means that with the buffer empty, the maximum access time (including error handling) is no more than 30 milliseconds.
