Else, remove the jumper. XXXXXXXXXXXXXXXXXXXXXXXXX J1 SCSI Connector TERMPWR (16-bit Drives, except SCA) ----------------------------------- To ensure that there is a sufficient level of power along the entire SCSI bus, Quantum Corporation recommends that all devices on the SCSI bus supply TERMPWR (if they are capable). SCSI devices are protected by a diode or similar seminconductor to prevent back flow of the terminator power when more than one device supplies this power. Active Termination (16-bit Drives, except SCA & Differential Models) -------------------------------------------------------------------- The drive can be configured to provide or not provide active termination. The drive location on the SCSI bus and the method used to terminate the SCSI bus (active termination or separate terminator) determines how to configure the active termination feature of the drive. NOTE XP31070WD/XP32150WD/XP34300WD drives cannot be configured to provide active termination. Do not install differential 16-bit drives at the end of the bus unless the bus is properly terminated (separate terminator resistor). Otherwise proper operation of the bus cannot be assured. Refer to your system or SCSI controller documentation regarding any specific recommendations regarding drive placement on the SCSI bus and SCSI bus termination. +------------------+------------------------------------------------+ |Drive installation|Active Termination Configuration | |location on SCSI | | |Bus | | +------------------+------------------------------------------------+ |Drive installed |If there is no separate bus terminator used at | |at end of bus |the SCSI bus end that contains the drive, | | |configured the drive to provide active | | |termination. | +------------------+------------------------------------------------+ |Drive installed |If a separate bus terminator IS used at the SCSI| |at end of bus |bus end that contains the drive, configure the | | |drive to NOT provide active termination. | +------------------+------------------------------------------------+ |Drive NOT |Configure the drive NOT to provide active | |installed at end |termination. | |of bus | | +------------------+------------------------------------------------+ Option Connctor +---+--+----+ To configure the drive to provide active termination, |o X o o o 1| install a jumper as shown. |o X o o o o| 12--+--+----+ NOTE XP31070WD/XP32150WD/XP34300WD drives do NOT support active termination. SCSI ID (16-bit Drives, except SCA) ----------------------------------- Each SCSI device on the bus must have a unique SCSI ID number assigned to it. The drive can be configured for SCSI ID numbers that range from 0 through 15. Set the SCSI ID for the drive at 12-pin Option connector.

Then connect the leads from the external selection switch(es) to the referenced pins. Observe the following guidelines while doing so. - ID Bit 0, at Pin 1, is the Least Significant Bit. - SCSI ID Bits 0, 1, 2 and 3 (pins 1, 3, 5 and 7, respectively) are active LOW signals. That is, the bit is a 1 if the corresponding remote switch is closed to ground. - Use pins 2, 4, 6 and 8 as the associated ground returns for ID bits 0, 1, 2, and 3, respectively. The ground returns can be used individually, or the ground returns of all three ID bits can be combined at pin 2, 4, 6 or 8. Spindle Synchronization 16-bit Drives, except SCA ------------------------------------------------- +--- LOGIC_GND L +2-----------14 |o o o o o o| |o o o o o o o| Secondary Option Connector +1------------+ +--- SPINDL_SYNC_REF L The drive supports synchronized spindle operation. Whether the drive operates as master or slave is determined by the contents of the RPL field in the Rigid Disk Geometry Page (04h) for the drive. The time interval between spindle synchronization checks is set using the Spindle Sync Check Interval bit of the SCSI MODE SELECT command Special Function Control page (25h). The drive always maintains local speed regulation when no reference signal is applied. When the drive operates as a master, it generates a spindle synchronization reference signal (SPINDL_SYNC_REF L). This reference signal is available as an output to other drives at Secondary Option connector pins 5 and 6 (pins 5 and 6 are connected together on the drive). When the drive operates as a slave, it looks for a spindle synchronization reference signal (SPINDL_SYNC_REF L) as an input from the master drive. The slave looks for this spindle synchronization input at either pin 5 or 6 on the Secondary option connector (pins 5 and 6 are connected together in the drive). CAUTION Atlas series drives can be connected for synchronized spindle operation. Models XP31070, XP32150 and XP34300 drives must not be used for synchronized spindle operation in conjunction with drives from different model series or unpredictable results might occur. For example, XP31070W, XP32150W and XP34300W drives can be connected for spindle synchronization in the same system, but they must not include a synchronization connection to a DSP3210W or Capella series disk drive. NOTE When connecting multiple drives together for spindle synchronization, be sure to use proper cabling techniques to avoid ground loop problems. Attach the spindle synchronization (SPINDL_SYNC_REF L) connection and associated ground connection at the secondary Option connector, pin 5. Connect the associated ground to pin 6. Write Protection 16-bit Drives, except SCA ------------------------------------------ +2-----------14 |o o X o o o| |o o o X o o o| Secondary Option Connector +1------------+ To write protect the drive, install a jumper across Secondary Option connector pins 7 and 8. To disable write protection, remove the jumper. Spin Up Power On 16-bit Drives, except SCA ------------------------------------------ +2-----------14 |X o o o o o| |X o o o o o o| Secondary Option Connector +1------------+ Atlas drives have three Spin-Up on Power On modes: - Option 1 Spin up occurs immediately when power is applied - Option 2 Drive spin up occurs after a predetermined delay following power on. The delay is equal to a user-specified multiplier, multiplied by one plus the numerical SCSI ID of the drive. This will give a staggered spin-up in multiple-drive installations. - Option 3 Drive spin up is controlled by the START STOP UNIT command. For Option 1, immediate spin up power on, install the jumper across pins 1 and 2 of the Secondary Option connector. For Option 2, spin up after a delay, install the jumper across pins 1 and 2 of the Secondary Option connector. Set delay parameters in the MODE SELECT command, Quantum (Vendor) Special Function Control Page (25h). For Option 3, spin up controlled by the START STOP UNIT command, remove the jumper (if present) from across pins 1 and 2 of the Option connector. Remote Busy and Fault Displays 16-bit drives, except SCA --------------------------------------------------------- Busy and Fault status of the drive can be monitired remotely by connecting remote (external) Busy and remote Fault display LEDs to the Secondary Option connector. Remote Busy LED --------------- Connect the cathode side of the remote Busy LED to pin 11, BSY_OUT L. Connect the anode side of the LED to pin 13, +5VDC OUT. Remote Fault LED ---------------- Connect the cathode side of the remote Fault LED to pin 14, FLT_OUT L.

Caching ------- The disk cache is a look-ahead buffer used for combining or coalescing I/O commands on a track-by track basis prior to accessing the disk media. Throughput performance is greatly improved by gathering and combining commands on a track basis rather than on a command basis. With this unique system, multiple commands for a particular track are coalesced in the buffer before accessing the media. As a result, multiple I/O commands, that address a single track are logically combined, avoiding multiple disk accesses on multiple rotations. Since most reads and writes are sequential, buffering data before it is stored on the media yields greatly increased throughput for most applications. The drive electronics contains a 1MB segmented buffer that maximizes the cache hit rate for sequential read streams. The cache is organized in RAM as separate track line segments. Each track line segment can hold data from one complete track on the media, temporarily assuming the identity of the track for all input/output functions. Embedded Servo System --------------------- Embedded servo information is written in a spoke configuration, 54 times on every track, on every disk surface. The spokes (or headers) consist of quadrature analog pattern and digital address data. The digital portion of the spoke data are read and used to locate the desired track, spoke, and head number. The quadrature analog signal portion is detected and used by a servo feedback control loop to precisely position the head on the track center. Data integrity and security --------------------------- Atlas disk drives use a combination of parity checking, error detection coding (EDC), error correction coding (ECC), and check- pointing to protect stored data from media errors, transfer or addressing errors, or errors introduced during sector reallocation. Media Error Protection ---------------------- To ensure that data is the same as data written, the drive computes and appends an Error Correction Code (ECC) to each sector of data stored. The drive uses a 198-bit Reed Solomon code. This allows correction of up to 10 bytes in each sector. The ECC can correct a single burst error up to 73 bits in length or a double burst error up to 25 bits in length for each burst. The drive has the capability of correcting in hardware ("on-the-fly") a single burst error up to 25 bits long with no increase in latency time. Spindle Synchronization ----------------------- Spindle Synchronization is the process of causing the disk assemblies in several disk drives to rotate to the same address location at the same time. Synchronization is used in RAID (redundant arrays of independent devices) mass storage systems, allowing a set of disk drives to function as one drive. To accomplish this, sector 0, track 0 of each drive must be under the read/write heads at exactly the same time. With spindle synchronization, all the drives are locked to the same relative position. If all the drives are synchronized exactly, the time used to access one drive results in the next drive passing the correct position. This problem is resolved by using an offset that is the sum of the transmission delays of the interconnecting bus cable, data transfer times, and the rotational latency of the drives. Knowing how long it takes to set up an I/O operation and transfer data to a drive, the SCSI controller can send the data to one drive and, while that data is being transferred, set up the I/O transfer to the next one. When the current transfer is complete, the controller is ready to transfer the next, and so on. Spindle Synchronization is controlled by the Rigid Disk Geometry and (Vendor) Special Function Control pages of the MODE SELECT command. NOTE The drives must be homogenous. Other drive model series such as Capella cannot function with Atlas-series drives. Special Functions ----------------- Quantum has incorporated a number of unique options into the drive. The (Vendor) Special Function Control page is used to control these options. The options include: - Spin Delay - delays the spin-up of the drive to reduce startup load of system power. - Initiate Synchronous Data Transfer Negotiation - a toggle-type parameter that allows the initiator to move between asynchronous and synchrounous modes of data transfer. - Slow Cable - adds an additional delay to REQ/ACK for very long bus cables. - No Multiple Active I/O Process - a toggle-type command to enable/ disable multiple I/O process. - Force Disconnect - the drive can be forced to disconnect from the SCSI bus after a SCSI Command is received in order to reduce on-bus time. Force Disconnect works only when a typical, error-free command is received. - Write Protect - Prevents writing to the disk drive. - Spindle Sync Check Interval - specifies the time, in minutes, of the interval between spindle synchronization status checks. - Stagger Spin Delay - specifies the time in 100 ms increments of the delay the drive uses in the spin-up delay formula, allowing a series of drives to be spin up at staggered time intervals. Banded recording ---------------- In banded recording, the disk is divided into multiple bands or partitions (also called notches or bit-zoned areas). Starting at inner band, each next outer band has a hihger recording frequency. The Atlas drives have 16 bands. The use of multiple-frequency recording greatly increases the capacity of the drive. Diagnostics ----------- The drive has extensive diagnostic capabilities, including those described below: power-up self-test, periodic self-adjustments, and host diagnostics. Quantum uses self-diagnostic tests and sense data tracking to manage drive errors, in addition to logical sector address (LBA) revectoring. Power-Up Self-Test ------------------ The disk drive performs a self-diagnostic test immediately at power up. If the drive fails its self-diagnostic tests, it will report sense information but will not spin up. Both the Fault LED and a Busy LED briefly illuminate during spin-up as a lamp test. If the drive passes its self-tests and the spin-up jumper is installed, it spins up and perform further diagnostics on the HDA. The drive indicates "not ready" until the HDA tests are completed successfully. The drive diagnostics test the following: - Drive master microprocessor - RAM and ROM chips - Buffer memory - Gate array chips - Read/write encoding circuits - Basic servo functions - SCSI interface control circuits Following a selection time after power-on, the disk drive is able to respond with appropriate status and sense data to the TEST UNIT READY, INQUIRY, and REQUEST SENSE commands.
