Miyezo ya SCSI siigwiritsidwanso ntchito pa zipangizo zamagula
SCSI ndi mtundu wotchuka kwambiri wa kugwirizana kwa yosungirako ndi zipangizo zina pa PC. Mawuwo amatanthauza zingwe ndi madoko omwe amagwiritsidwa ntchito pogwirizanitsa mitundu yina ya magalimoto oyendetsa , makina opangira , ma scan, ndi zipangizo zina zapakompyuta .
Makhalidwe a SCSI sagwiranso ntchito pakati pa zipangizo zamagetsi, koma mumapezebe SCSI m'makondomu ena amalonda. Mabaibulo atsopano a SCSI akuphatikizapo USB Attached SCSI (UAS) ndi Serial Attached SCSI (SAS).
Ambiri opanga makompyuta amasiya kugwiritsa ntchito SCSI kwathunthu ndipo amagwiritsa ntchito miyezo yomwe imatchuka kwambiri, monga USB ndi FireWire , polumikiza zipangizo zakunja ku makompyuta. USB imapita mofulumira kuposa SCSI ndi liwiro lopitirira la 5 Gbps ndi liwiro loyandikira lomwe likuyandikira 10 Gbps.
SCSI yakhazikitsidwa ndi mawonekedwe akale omwe amatchedwa Shugart Associates System Interface (SASI), yomwe idasinthika ku Small Computer System Interface, yotchulidwa ngati SCSI ndipo imatchulidwa "mosasamala."
Kodi SCSI Zimagwira Ntchito Bwanji?
Mapulogalamu SCSI amagwiritsidwa ntchito mkati mwa makompyuta kuti agwirizanitse mitundu yosiyanasiyana ya zipangizo za hardware mwachindunji ku makina a maibo kapena makasitomala oyang'anira yosungirako. Pogwiritsidwa ntchito mkati, zipangizo zimagwiritsidwa ntchito kudzera mu chingwe cha riboni.
Kulumikizana kwa kunja kumakhalanso kofala kwa SCSI ndipo nthawi zambiri kumagwirizanitsa kudzera pa doko lakunja pa khadi loyang'anira yosungirako pogwiritsa ntchito chingwe.
Mtsogoleriyo ndi chipangizo chakumbuyo chomwe chimagwira BSIOS SCSI, yomwe ndi pulogalamu yowonjezera yomwe imagwiritsidwa ntchito poyendetsa zipangizo zogwirizana.
Kodi Zosiyanasiyana Zamakono za SCSI ndi Ziti?
Pali magulosi osiyanasiyana a SCSI omwe amathandiza maulendo osiyanasiyana osiyanasiyana, mofulumira, ndi chiwerengero cha zipangizo zomwe zingagwirizane ndi chingwe chimodzi. Nthaŵi zina amatchulidwa ndi gulu lawo la mabasi ku MBps.
Kuyambika mu 1986, SCSI yoyamba imagwiritsa ntchito zipangizo zisanu ndi zitatu zokhala ndi maulendo asanu ndi awiri. Mabaibulo obwera mofulumira anadza mofulumira ndi ma 320 MBps ndi kuthandizira zipangizo 16.
Nazi zina mwazigawo zina za SCSI zomwe zakhalapo:
- Kukula kwa SCSI: 10 MBps; imagwirizanitsa zipangizo zisanu ndi zitatu
- Fastest SCSI: 20 MBps; imagwirizanitsa zipangizo 16
- Ultra Wide SCSI: 40 MBps; imagwirizanitsa zipangizo 16
- Ultra3 SCSI: 160 MBps; imagwirizanitsa zipangizo 16
- Ultra-640 SCSI: 640 MBps; imagwirizanitsa zipangizo 16
