Tsarin SCSI ba'a amfani da shi a hardware mara amfani
SCSI wani nau'in haɗin kai ne da ke da sau ɗaya don ajiya da wasu na'urori a PC. Kalmar tana magana akan igiyoyi da kuma tashoshin da ake amfani da su don haɗa wasu nau'ikan kwarewa , masu kwashe-kwane , masu dubawa, da wasu na'urorin haɗi zuwa komfuta.
Tsararwar SCSI ba ta kasancewa ɗaya tsakanin na'urori masu amfani ba, amma har yanzu za ka sami SCSI a wasu shafukan kasuwanci da kuma shafukan yanar gizo. Sakamakon sauti na SCSI sun hada da USB Attached SCSI (UAS) da Serial Attached SCSI (SAS).
Yawancin masana'antun kwamfuta sun daina amfani da SCSI a kan gaba daya kuma suna amfani da ka'idodin da suka fi shahara, kamar USB da FireWire , don haɗa na'urorin waje zuwa kwakwalwa. Kebul yana da sauri fiye da SCSI tare da ci gaba da gudu na 5 Gbps kuma matsakaicin gudunmawar mai shiga kusan 10 Gbps.
SCSI na dogara ne akan wani tsofaffi wanda ake kira Shugart Associates Interface Interface (SASI), wanda daga bisani ya samo asali a cikin Ƙananan Tsarin Kwamfuta na Intanet, ya rage kamar SCSI kuma ya furta "scuzzy."
Ta yaya SCSI aiki?
Siffofin SCSI da aka yi amfani da shi a cikin kwakwalwa don haɗi da nau'ikan kayan na'urorin kayan aiki daban-daban zuwa katin katako ko katin ajiya. Lokacin da aka yi amfani da shi a cikin gida, an haɗa na'urori ta hanyar rubutun igiya.
Hanyoyin sadarwa na waje suna mahimmanci ga SCSI kuma yawanci sun haɗa ta hanyar tashar waje a katin katin kulawa ta amfani da kebul.
A cikin mai sarrafa shi ƙwaƙwalwar ƙwaƙwalwar ajiyar da ke riƙe da SCSI BIOS, wanda shine wani ɓangaren software wanda ke amfani da shi don sarrafa na'urorin da aka haɗa.
Mene ne Siffofin SCSI daban-daban?
Akwai fasahohin SCSI daban-daban masu goyon bayan daban-daban na tsawon lokaci na USB, gudu, da kuma yawan na'urorin da za a iya haɗe zuwa ɗaya na USB. A wasu lokutan ana magana da su ta hanyar baswidth na bus a MBps.
Debuting a 1986, sashe na farko na SCSI ya goyi bayan na'urori takwas tare da iyakar matsakaicin sauƙin gudu na 5 MBps. Sauye-sauye ya zo daga baya tare da gudu daga 320 MBps da goyon bayan ga na'urorin 16.
Ga wasu ƙananan kamfanonin SCSI da suka wanzu:
- Fast SCSI: 10 MBps; haɗi da na'urorin takwas
- Fast Wide SCSI: 20 MBps; haɗi 16 na'urorin
- Ultra Wide SCSI: 40 MBps; haɗi 16 na'urorin
- Ultra3 SCSI: 160 MBps; haɗi 16 na'urorin
- Ultra-640 SCSI: 640 MBps; haɗi 16 na'urorin
