Umgangatho we-SCSI awusasetyenzisiwe kwi-hardware yabathengi
I-SCSI luhlobo oluthile oludumiweyo lokunxibeleliswa kunye nezinye izixhobo kwi-PC. Eli gama libhekisela kwizixhobo kunye neechweba ezisetyenziselwa ukudibanisa iindidi ezithile zokuqhuba okukhuni , ii-optical drives , i-scanners, kunye nezinye iifowuni zecomputer kwikhompyutha.
Umgangatho we-SCSI awuqhelekanga phakathi kwezixhobo zokusebenza ze-hardware, kodwa uya kufumana i-SCSI kwimihlaba ethile yeshishini kunye ne-server. Iinguqulelo zakutshanje ze-SCSI ziquka i-USB ejoliswe kwi-SCSI (i-UAS) kunye ne-Serial Attached SCSI (SAS).
Uninzi lwabenzi bekhompyutheni bayeka ukusetyenziswa kwi-SCSI ngokupheleleyo kwaye basebenzise imilinganiselo ethandwa kakhulu, njenge- USB kunye ne- FireWire , ngokuxhuma amadivayisi angaphandle kwiikhomputha. I-USB inokukhawuleza ngaphezu kwe-SCSI enejubane eliqhubekayo le-5 Gbps kunye nesantya esiphezulu esingafikayo esifikelela kwi-10 Gbps.
I-SCSI isekelwe kwi-interface ekhulile ebizwa ngokuba yiShugart Associates System Interface (SASI), eyaza yavela kwi-Interface yeNkqubo yeComputer encinci, isicatshulwa njengeSSCSI kwaye yathi "i-scuzzy".
I-SCSI isebenza njani?
I-SCSI interfaces ezisetyenziselwa ngaphakathi ngaphakathi kwiikhomputha ukudibanisa iindidi ezahlukeneyo zeefowuni ze- hardware ngqo kwi- motherboard okanye kwikhadi lomlawuli wokugcina. Xa zisetyenziswe ngaphakathi, iifowuni ziqhotyoshelwe ngetambo yebhebhoni.
Ukuxhuma kwangaphandle kuqhelekile kwi-SCSI kwaye ngokuqhelekileyo kudibanisa nge-port yangaphandle kwikhadi lomlawuli wokugcina usebenzisa ikhebula.

Ziziphi i-SCSI Technologies ezahlukeneyo?
Kukho ubuchwepheshe obuhlukahlukeneyo be-SCSI obuxhasa ubude beekhebhu ezihlukeneyo, ukukhawuleza, kunye nenani lamadivaysi anokuqhotyoshelwe kwenye ikhebula. Ngamanye amaxesha kuthethwa ngabo ibhasi lomda weBhasi kwi-MBps.
Ukuqala ngo-1986, inqaku lokuqala le-SCSI lixhasayo izixhobo ezisibhozo ezinezantya ezithe gqithwayo zokuhamba kwe-5 MBps. Iinguqulelo ezikhawulezayo zafika kamva ngezantya ezingama-320 MBps kunye nenkxaso kumadivayisi angama-16.
Nazi ezinye ze-SCSI interfaces ezikhoyo:
- I-SCSI ekhawulezayo: 10 MBps; idibanisa izixhobo ezisibhozo
- I-SCSI ngokukhawuleza: 20 MBps; idibanisa izixhobo ezili-16
- I-Ultra Wide SCSI: 40 MBps; idibanisa izixhobo ezili-16
- I-Ultra3 SCSI: 160 MBps; idibanisa izixhobo ezili-16
- I-Ultra-640 SCSI: 640 MBps; idibanisa izixhobo ezili-16
