3.3 Physical Configuration Winchester disk drives The Winchester hard disk drives (imodzi, ziwiri, kapena zinayi zingakhalepo) zimayikidwa pa Ma tray awiri a Winchester Drive, okhala mu Winchester Disk Assembly yomwe imakhala ndi mipata iwiri yapamwamba (mipata 4 ndi 5) ya gawo monga momwe tawonetsera mu Zithunzi 3-32. Mabasi a SCSI olumikizana ndi Dual Small Computer Systems Interface, (SCSI) zingwe za riboni za basi zimalumikiza gulu ladera la Smart Peripheral Controller I/O (SPCII/SPC2), lomwe lili kumbuyo kwa Smart Peripheral Controller (SPC) dera board (slot 2), kupita ku Winchester Drive Interface I/O (WDI I/Ort circuit ya Winchester) 5). Winchester Drive Interface (WDI) board board, yomwe ili mu Winchester Disk Assembly (WDA), imakulitsa basi ya SCSI kudutsa ma flex-circuits osindikizidwa kupita ku Winchester disk drive(ma) yoyikidwa pa Winchester Drive Tray(s) monga momwe tawonetsera pa Chithunzi 3-5. Mabasi "amagawanika" pa bolodi la dera la WDI I/O, kupereka mawonekedwe a basi ku Winchester Drive Tray iliyonse. Smart Peripheral Controller (SPC) board board imalumikizana ndi chingwe cha riboni ya basi ya SCSI ndikusindikiza flex-circuit yokhala ndi ma drive amodzi kapena awiri pa tray iliyonse yomwe ilipo. Basi ya SCSI imathetsedwa ndi ma module omaliza omwe amaikidwa pagalimoto yomaliza (yomaliza). Kuyimitsa basi ya SCSI Pamene thireyi ili ndi disk imodzi ya Winchester disk yoyikidwapo, galimotoyo imayikidwa kutsogolo ndipo iyenera kukhala ndi ma modules atatu a mabasi omwe amaikidwa pa galimotoyo ngati ndi 210 megabyte kapena 445 megabyte drive. Ma drive a 875 megabyte ndi 1.8 gigabyte alibe ma module othetsera mabasi. M'malo mwake, zoyimitsa mabasi zamkati zimayatsidwa pakompyuta pagalimoto posankha jumper block. Ngati galimoto yachiwiri ya Winchester disk ikupezeka pa tray, galimoto yachiwiri imayikidwa kumbuyo kwa tray popanda ma modules ochotsera mabasi a SCSI omwe amaikidwapo monga momwe tawonetsera pa Chithunzi 3-5. Bungwe loyang'anira dera la WDI, lokhala mu Winchester Disk Assembly, lili ndi ma seti awiri a SCSI resistor terminators, seti imodzi pa tray iliyonse. Seti ya zotsekera imatsegulidwa pamene mphamvu imachotsedwa pa Winchester Drive Tray ndi chosinthira mphamvu kutsogolo kwa thireyi. Dongosololi limalola kuti galimoto yomwe yalephera pa thireyi ichotsedwe ndikusinthidwa popanda kusokoneza mnzake yemwe wayikidwa pa tray ina, ndikulumikizana ndi basi ya SCSI yomweyo.
