- I-QSFP (iQuad Small Form-factor Pluggable) yinkqubo yonxibelelwano lwenethiwekhi ekhawulezayo, kwaye i-SFF-8436 yinkcazo yayo ehambelanayo. I-QSFP interface ixhasa ukuhanjiswa kwedatha ekhawulezayo ye-40Gbps kwaye isetyenziswa rhoqo kumaziko edatha, kwikhompyutha esebenza kakhulu, kwiiswitshi zenethiwekhi nakwezinye izixhobo, okuvumela uqhagamshelo lwenethiwekhi olukhawulezayo phakathi kwezixhobo.
- Olu jongano luneempawu zobukhulu obuncinci, olunokutsalwa, kunye nenkxaso yokutshintshana okushushu, okwenza kube lula ukufakela, ukugcinwa, kunye nokuphucula izixhobo.
Uphawu lwemveliso:
- Uyilo Oluhle Lokukhusela: Intambo idla ngokuba nesakhiwo esihle sokukhusela, njengomaleko wokukhusela wesinyithi, njl.njl., onokunciphisa ngempumelelo impembelelo yokuphazamiseka kwe-electromagnetic yangaphandle kwisignali. Kwangaxeshanye, inokuthintela nesignali yangaphakathi ekuphazamiseni ingaphandle, iqinisekisa ubunyulu kunye nokuthembeka kwesignali.

Zithini iimpawu zeentambo ze-SAS kunye neentambo ze-SAS?
Intambo ye-SAS yindawo yokugcina idatha yediski, isixhobo esibaluleke kakhulu, yonke idatha kunye nolwazi kufuneka lugcinwe kwidiski. Isantya sokufunda idatha simiselwa lujongano lonxibelelwano lwediski. Kwixesha elidlulileyo, besisoloko sigcina idatha yethu nge-SCSI okanye i-SATA interfaces kunye nee-hard drives. Kungenxa yophuhliso olukhawulezayo lwetekhnoloji ye-SATA kunye neenzuzo ezahlukeneyo apho abantu abaninzi baya kuqwalasela ukuba kukho indlela yokudibanisa zombini i-SATA kunye ne-SCSI, ukuze iingenelo zazo zombini zidlalwe ngaxeshanye. Kule meko, i-SAS ivele. Izixhobo zokugcina idatha ezidityanisiweyo zinokwahlulwahlulwa zibe ziindidi ezintathu eziphambili, ezizezi, i-middle-end ephezulu kunye ne-near-end (Near-Line). Izixhobo zokugcina idatha ezikwi-high-end ikakhulu zii-Fibre channel. Ngenxa yesantya sokudlulisa idatha yeFibre channel, uninzi lwezixhobo zokugcina idatha ye-optical fiber ezikwi-high-end zisetyenziswa kwindawo yokugcina idatha yesitshixo semisebenzi emininzi. Isixhobo sokugcina idatha esikwi-middle-range ikakhulu zizixhobo ze-SCSI, kwaye sinembali ende, esetyenziswa kwindawo yokugcina idatha ebalulekileyo yenqanaba lorhwebo. Ifinyeziwe njenge (SATA), isetyenziswa ekugcinweni okukhulu kwedatha engengomsebenzi ubalulekileyo kwaye yenzelwe ukuthatha indawo yogcino lwedatha lwangaphambili kusetyenziswa iteyiphu. Eyona nzuzo ilungileyo yezixhobo zokugcina iFibre Channel kukudluliselwa ngokukhawuleza, kodwa inexabiso eliphezulu kwaye kunzima ukuyigcina; izixhobo ze-SCSI zinokufikelela ngokukhawuleza kunye nexabiso eliphakathi, kodwa ayinwebeki kangako, ikhadi ngalinye le-SCSI interface liqhagamshela ukuya kuthi ga kwi-15 (itshaneli enye) okanye izixhobo ezingama-30 (ezine-dual channel). I-SATA yiteknoloji ephuhla ngokukhawuleza kwiminyaka yakutshanje. Eyona nzuzo yayo inkulu kukuba ingabizi kakhulu, kwaye isantya asicothi kakhulu kune-SCSI interface. Ngophuhliso lwetekhnoloji, isantya sokufunda idatha se-SATA sisondela kwaye sidlula i-SCSI interface. Ukongeza, njengoko i-hard disk ye-SATA isiya ibiza kwaye ibiza kakhulu, ingasetyenziselwa ukugcina idatha kancinci kancinci. Ngoko ke indawo yokugcina yeshishini yendabuko kuba xa kujongwa ukusebenza kunye nozinzo, kunye ne-SCSI hard disk kunye ne-fiber optic channel njengeqonga lokugcina eliphambili, i-SATA isetyenziswa kakhulu kwidatha engabalulekanga okanye kwikhompyutha yomntu yedesktop, kodwa ngokukhula kwetekhnoloji ye-SATA kunye nezixhobo ze-SATA zivuthiwe, le ndlela iyatshintshwa, abantu abaninzi baqala ukuhoya i-SATA ngale ndlela yoqhagamshelo lokugcina idatha.
