Isilinganiso se-SCSI asisetshenziselwa i-hardware yabathengi
I-SCSI iyinhlobo ethandwa kakhulu yocingo lokugcinwa kwesitoreji namanye amadivayisi ku-PC. Leli gama lisho amakhodi namachweba asetshenziselwa ukuxhuma izinhlobo ezithile zezinkinobho ezinzima , ama-optical drives , ama-scanners, namanye amadivaysi omsakazo kwikhompyutha.
I-standard ye-SCSI ayisavamile phakathi kwamadivayisi we-hardware wezimpahla, kodwa usazothola i-SCSI kwezinye izindawo zebhizinisi nezebhizinisi. Izinguqulo zakamuva zamuva ze-SCSI zihlanganisa i-USB Okunamathiselwe SCSI (UAS) ne-Serial Attached SCSI (SAS).
Abakhiqizi abaningi bekhompuyutha bayeke ukusebenzisa usebenzisa i-SCSI ngokugcwele futhi basebenzisa izindinganiso ezithandwa kakhulu, njenge- USB ne- FireWire , ngokuxhuma amadivayisi angaphandle kuma-computer. I-USB isheshe kakhulu kune-SCSI enesisindo esiqinile esingu-5 Gbps kanye nesivinini esiphezulu esingenayo esondela ku-10 Gbps.
I-SCSI isekelwe isikhombimsebenzisi esidala esibizwa ngokuthi i-Shugart Associates System Interface (SASI), kamuva eya ku-Interface Small System System, isifinyeziwe njenge-SCSI futhi yathi "i-scuzzy".
I-SCSI isebenza kanjani?
Ama-SCP interfaces asetshenziselwa ngaphakathi kwamakhompyutha ukuxhuma izinhlobo ezahlukene zamadivaysi wehadiwe ngqo ekhadini le- motherboard noma lesilawuli sesitoreji. Uma isetshenziswe ngaphakathi, amadivayisi afakwe ngekhebula lebhebhoni.
Ukuxhumeka kwangaphandle nakho kuvamile ku-SCSI futhi kuvame ukuxhuma ngechweba langaphandle ekhadini lokulawula isitoreji usebenzisa ikhebula.
Esikhathini sesilawuli kuyinsimu yokukhumbula ephethe i-SCSI BIOS, eyisiqeshana se-software ehlanganisiwe esetshenziswa ukulawula amadivayisi axhunyiwe.
Yiziphi i-SCSI Technologies ezahlukene?
Kunezinhlobo eziningi zobuchwepheshe be-SCSI ezisekela ubude bekhebula, ukuvinjelwa, kanye nenani lamadivaysi angathintwa nekhebula elilodwa. Ngezinye izikhathi kuthiwa yi- bandwidth yabo yebhasi ku-MBps.
Ukuqala ngo-1986, inguqulo yokuqala ye-SCSI isekela amadivayisi ayisishiyagalombili anejubane lokudlulisa elingu-5 MBps. Izinguqulo ezisheshayo zafika ngokuhamba kwesikhathi ngesivinini se-320 MBps nokusekelwa amadivayisi angu-16.
Nazi ezinye ze-SCSI interfaces ezikhona:
- I-SCSI Fast: 10 MBps; ixhuma amadivayisi ayisishiyagalombili
- I-SCSI e-Fast Wide: 20 MBps; ixhuma amadivayisi angu-16
- I-Ultra Wide SCSI: 40 MBps; ixhuma amadivayisi angu-16
- I-Ultra3 SCSI: 160 MBps; ixhuma amadivayisi angu-16
- I-Ultra-640 SCSI: 640 MBps; ixhuma amadivayisi angu-16
