3.3 Tsarin Jiki na Winchester faifai na Winchester rumbun kwamfutarka (ɗaya, biyu, ko huɗu za su iya kasancewa) ana hawa a kan Winchester Drive Trays guda biyu, mazaunin Winchester Disk Assembly wanda ya mamaye manyan ramummuka biyu na allon kewayawa (ramuka 4 da 5) na tsarin kamar yadda aka kwatanta a Figures 3-2 da 3-3 SCSI bas interconnections Dual Small Computer Systems Interface, (SCSI) bas ribbon igiyoyi haɗa Smart Peripheral Controller I/O (SPCII/SPC2) kewaye allon, wanda yake a baya na Smart Peripheral Controller (SPC) kewaye allon (ramuka 2), zuwa Winchester Drive Interface I/O (WDI I/O/WDI) da'irar Majalisar 5). Wurin kewayawa na Winchester Drive Interface (WDI), wanda ke cikin Winchester Disk Assembly (WDA), yana faɗaɗa bas ɗin SCSI ta hanyar bugu biyu na flex-circuits zuwa Winchester faifai diski da aka ɗora akan Winchester Drive Tray(s) kamar yadda aka kwatanta a hoto 3-5. Motar bas ɗin ta “raba” akan allon kewayawa na WDI I/O, tana ba da hanyar haɗin bas zuwa kowane Winchester Drive Tray. The Smart Peripheral Controller (SPC) allon kewayawa yana haɗuwa ta hanyar kebul na ribbon bas na SCSI da bugu mai sassauƙa tare da tuƙi ɗaya ko biyu akan kowane tire da ke akwai.
