3.3 Physical Configuration Winchester disk drives The Winchester hard disk drives (imwe, mbiri, kana ina inogona kuvapo) yakasungirirwa pamatireyi maviri eWinchester Drive, anogara muWinchester Disk Assembly iyo inotora nzvimbo dzepamusoro mbiri dzebhodhi slots (slots 4 uye 5) yemodule sezvinoratidzwa muFigures 3-32. Mabhazi eSCSI anobatanidza Dual Diki Computer Systems Interface, (SCSI) tambo dzeribhoni dzebhazi dzinobatanidza Smart Peripheral Controller I/O (SPCII/SPC2) bhodhi redunhu, riri kuseri kweSmart Peripheral Controller (SPC) redunhu bhodhi (slot 2), kuWinchester Drive Interface I/O (WDI I/arar Assembly yeDisiki reWinchester Assembly/WDI) 5). Iyo Winchester Drive Interface (WDI) yedunhu bhodhi, iri muWinchester Disk Assembly (WDA), inotambanudza bhazi reSCSI kuburikidza maviri akadhindwa flex-circuits kuenda kuWinchester disk drive (s) akaiswa paWinchester Drive Tray (s) sezvakaratidzwa mumufananidzo 3-5. Bhazi "rinotsemuka" paWDI I/O redunhu bhodhi, richipa iyo bhazi interface kune yega yega Winchester Drive Tray. Iyo Smart Peripheral Controller (SPC) yedunhu bhodhi inobatanidza neSCSI bhazi ribhoni tambo uye yakadhindwa flex-circuit ine imwechete kana maviri madhiraivha patireyi yega yega iripo. Bhazi reSCSI rinomiswa nemamodule ekumisa akaiswa pane yekupedzisira (yekupedzisira) drive. SCSI kumiswa kwebhazi Kana tireyi iine imwe Winchester disk drive yakaiswa pairi, dhiraivha inoiswa pamberi penzvimbo uye inofanira kunge ine matatu mabhazi ekumisa mamodule akaiswa padhiraivha kana iri 210 megabyte kana 445 megabyte drive. Iwo 875 megabyte uye 1.8 gigabyte madhiraivha haana mabhazi ekumisa mamodule. Pane kudaro, materminator emukati emabhazi anogoneswa nemagetsi padhiraivha nejumper block sarudzo. Kana yechipiri Winchester disk drive iripo patireyi, yechipiri dhiraivha inoiswa munzvimbo yekumashure pane tireyi isina SCSI bhazi termination modules yakaiswa pairi sezvakaratidzwa muFigure 3-5. Iyo WDI yedunhu bhodhi, inogara muWinchester Disk Assembly, ine maviri seti eSCSI bhazi resistor terminators, imwe seti yetireyi yega yega. Iyo seti yematerminator inogadziriswa kana simba rabviswa kubva kune mumwe munhu Winchester Drive Tray nemagetsi switch pamberi petireyi. Urongwa uhwu hunobvumira dhiraivha yatadza patireyi kuti ibviswe uye kutsiviwa pasina kukanganisa mumwe wayo akaiswa pane imwe tireyi, achipindirana nebhazi reSCSI.
