SCSI cov qauv tsis siv nyob hauv kev kho vajtse
SCSI yog ib hom xov xwm zoo tshaj plaws rau kev cia khoom thiab lwm yam khoom siv hauv PC. Lo lus yog hais txog cov cables thiab cov chaw nres nkoj uas siv los mus txuas rau qee yam hom kev xuab zeb , kev tsav qhov muag , lub tshuab hluav taws xob, thiab lwm yam cuab yeej ntawm lub computer.
SCSI cov qauv tsis yog kev sib ntau ntawm cov khoom siv kho vajtse, tab sis koj tseem yuav pom SCSI hauv qev lag luam thiab cov chaw ua haujlwm hauv cov chaw ua haujlwm. Tsis ntev los no versions of SCSI xws li USB Attached SCSI (UAS) thiab Serial Attached SCSI (SAS).
Feem ntau ntawm cov tshuab computer tau nres siv kev SCSI tag thiab siv cov qauv uas nrov dua, xws li USB thiab FireWire , rau kev siv txuas sab nraud rau cov computers. USB yog sai dua li SCSI nrog ib tug ceev ceev ntawm 5 Gbps thiab siab tshaj plaws ntawm kev mus nce 10 Gbps.
SCSI yog nyob ntawm ib qho interface hu ua Shugart Associates System Interface (SASI), uas yog hloov mus ua Me Computer Computer Interface, ua daim SCSI thiab qhia tau "qaug zog."
SCSI Ua Haujlwm Li Cas?
SCSI interfaces siv hauv internally hauv computer mus txuas rau ntau hom kev kho vajtse khoom ncaj qha mus rau ib daim npav motherboard los sis daim npav. Thaum siv nyob hauv tsev, cov cuab yeej siv txuas los ntawm kab xov cable.
Cov kev sib txuas sab nraud kuj muaj rau SCSI thiab feem ntau txuas ntawm qhov chaw nres nkoj sab nraud ntawm ib tus neeg khaws khoom cia siv ib kab ntawv.
Tsis pub dhau lub maub los yog lub cim xeeb nti uas tuav tus SCSI BIOS, uas yog ib daim software uas siv los tswj cov khoom siv txuas.
Cov Kev Sib Txawv Sib Tw Sai Li Cas SCSI?
Muaj ntau ntau yam SCSI cov yees uas txhawb ntau hom kab lengths, speeds, thiab naj npawb ntawm cov khoom siv uas txuas nrog rau ib kab ntawv. Lawv qee zaum raug xa mus los ntawm lawv cov kev caij npav rau hauv MBps.
Debuting nyob rau hauv 1986, thawj version ntawm SCSI txhawb kev pabcuam li nrog rau siab tshaj plaws ntawm 5 MBPS. Faster versions tuaj nrog qeeb ntawm 320 MBps thiab kev them nyiaj yug rau 16 pab kiag li lawm.
Nov yog qee qhov SCSI interfaces uas tau muaj nyob rau hauv:
- Fast SCSI: 10 MB; sib txuas yim pab
- Ceev ceev SCSI: 20 MB; txuas 16 khoom
- Ultra Wide SCSI: 40 MB; txuas 16 khoom
- Ultra3 SCSI: 160 MBps; txuas 16 khoom
- Ultra-640 SCSI: 640 MBps; txuas 16 khoom
