Never install PCA to the top! Ambient temperature ------------------- When the IDD is operating, the ambient temperature measured 3 cm from the Disk Enclosure (DE) surface and from the PCA surface must satisfy the specified requirements. Multi-drive connection ---------------------- Host systems, IDDs and other SCSI controllers are connected (daisy chained) to SCSI provided that the total number of connected SCSI devices is a maximum of eight. SCSI cable ---------- The total length of SCSI interface cable must be shorter than 7m. A characteristic impedance of 100 10% is recommended for unshielded twisted-pair ribbon cable. A characteristics impedance greater than 90 is preferred for shielded cable. A minimum conductor size of 28 AWG shall be employed. It is recommended that shielded cable be used for connection outside of a cabinet. To minimize discontinuities and signal reflections, cables of dif- ferent impedance should not be used in the same bus. The maximum cable length is 7m. 1m or more cable length is recommended between SCSI devices. Check, that system power is off before connecting or disconnecting cables! Be carefull of the insertion directions of the SCSI connectors. With the system in which terminating resistor power is supplied via the SCSI cable, if the drive power is turned on, the overcurrent protec- tion fuse of the terminating resistor power supplier may be blown or the cable may be burnt if overcurrent protection is not provided. Terminator ---------- All SCSI devices on one bus are daisy-chained with a SCSI cable. A terminating resistor must be mounted in the SCSI device at each end of the SCSI cable. Since a SCSI terminating resistor module is mounted in the IDD on shipment, it must be removed when the IDD is not connected at either end of the SCSI cable. Also, a method for the power supply to the terminating resistor must be selected with the setting terminal on the IDD. When connecting the IDD to either end of the SCSI cable, do not de- mount the terminating resistor module. When connecting the IDD to a position other than both ends of the SCSI cable, demount terminating resistor modules.

Therefore, if more than one IDD is used, the spindle motors should be started sequentially using one of the following procedures: 1. Issue START/STOP UNIT commands at 20-second intervals to start the spindle motors. 2. Turn on the +12 V DC power in the power supply unit at 30-second intervals to start the spindle motors sequentially. Noise filter ------------ To eliminate AC line noise, a noise filter should be installed at the AC input terminal on the IDD power supply unit. Attenuation: 40 dB or more at 10 MHz.

In addition, power- ful Vendor Unique Commands have been provided to improve data hand- ling capability. These commands can manipulate data through logical block addressing independent of the physical characteristics of the IDD. Command queuing --------------- IDD can accept multiple commands from multiple hosts. Data error correction --------------------- If a recoverable error occurs, IDD attemps to recover errors from in- side the IDD. Correctable data error can be corrected in the data buffer so that error-free data can be transferred to the host system. Mean Time Between Failures (MTBF) --------------------------------- The estimated MTBF of the IDD during its life time is 30.000 hours after an initial 3-month period. Mean Time To Repair (MTTR) -------------------------- MTTR is the average time taken by a well-trained service mechanic to diagnose and repair a unit malfunction. IDD is designed for a MTTR of 30 minutes or less. Service life ------------ Overhaul of the drive is not required for the first five years. Power loss ---------- Integrity of the data of the disk is guaranteed against all forms of abnormal DC power failure except a power failure during writing. Media defects ------------- Cylinder 0, Head 0 and 1 are error free. M2247S/SA/SB Fewer TBD M2248S/SA/SB Fewer TBD M2249S/SA/SB Fewer TBD The maximum defect length is 32 byte. Sector interleaving ------------------- Sector interleaving enables the data transfer rate required on SCSI during read or write operation of continuous blocks to be decreased. To use sector interleaving, the user must reformat the disk drive by a Format Unit command. The Format Unit command permits a sector in- terval between blocks to be specified as an interleaving factor. The user need not be concerned with correspondences of blocks with their physical sector locations, because any data access after the comple- tion of formatting is performed in accordance with the block arran- gement. In sector interleaving mode, the data blocks in a drive are accessed at intervals of (m) sectors, where (m) is determined by the inter- leaving factor. In read/write operations on continuouse blocks in the sector interleaving mode, the data buffer helps decrease data trans- fer rate required in SCSI. The data transfer rate in SCSI required to maintain continuouse block processing without unexpected revolu- tion delay when the interleaving factor is (m) can be determined by the following expression: 1.25MB/s x data field length SCSI average data transfer rate ---------------------------------- physical sector length x (m)
