Ukuqonda ezi ntambo zintathu Yintoni umahluko phakathi kwe-SFF 8482,I-Oculink SFF 8611 kunye ne-SFF-8643？
Kwicandelo lokusasazwa kwedatha ngesantya esiphezulu kunye noqhagamshelo olude, iintambo zobungcali zisebenza njengeebhulorho ezibalulekileyo zokufezekisa impumelelo yokusebenza. Phakathi kwazo,I-SFF 8482ezimbini kwintambo enye,I-PCIE Oculink SFF 8611 4I to Intambo ye-SFF-8643, kwaye iIkhebula le-Oculink SFF 8611 4IIi-e zikhokela indlela ngoyilo lwazo oluchanekileyo kunye nokusebenza okugqwesileyo, zityhala imida yezicelo ukusuka kwindawo yokugcina izinto ukuya kwikhompyutha esebenza kakhulu.
Okokuqala, masigxile kwiI-SFF 8482intambo ezimbini kwinye, ezimele uthumelo oluhlanganisiweyo lweetshaneli ezininzi. Le ntambo idibanisa ngobuchule iitshaneli ezimbini zibe yinye, isetyenziswa kakhulu kwiimeko ezifuna uthumelo oluhambelanayo olunebhendi ephezulu. Xa kuthelekiswa nenye efanayo.I-SFF 8482iintambo ezimbini kwelinye,Intambo ye-Oculink SFF 8611 4I, eyenzelwe ngokukodwa ukwandiswa kwetshaneli ye-PCIe, ijoliswe ngakumbi. Njengelungu eliphambili losapho lwe-Oculink (Optical Copper Link), umgangatho ngamnyeIntambo ye-Oculink SFF 8611 4Iifaka iipayi ezine ezizimeleyo ezinesantya esiphezulu, ukuqinisekisa ukuhanjiswa kwemiqondiso ye-PCIe enelahleko ephantsi kunye ne-low-latency.
Nangona kunjalo, ekudityanisweni kwenkqubo, ukwahluka kwezixhobo zonxibelelwano kudla ngokufuna izisombululo zokuguqula eziguquguqukayo. Kulapho keI-PCIE Oculink SFF 8611 4I toIntambo ye-SFF-8643iyazimela. Olu khetho lukhethekileyoI-PCIE Oculink SFF 8611 4I to Intambo ye-SFF-8643ine-interface encinci ye-Oculink kwelinye icala kwayeI-SFF-8643ujongano, olufumaneka rhoqo kwi-SAS expanders kunye ne-backplanes, kwelinye icala. Idibanisa i-PCIe protocol kunye ne-SAS environment, iphucula kakhulu ukuguquguquka koqwalaselo lwenkqubo. Nokuba kukudibanisa ii-GPU docks zangaphandle okanye ii-arrays zokugcina ezikhawulezayo, ukukhetha okulungileyo.I-PCIE Oculink SFF 8611 4I to Intambo ye-SFF-8643kubalulekile.
Ngokwembono yomzimba, umgangatho ophezuluIntambo ye-Oculink SFF 8611 4Iineemfuneko ezingqongqo zobuchwepheshe bokukhusela kunye nolawulo lwe-impedance yokuphatha imiqondiso yesantya esiphezulu se-GHz. Ngokwahlukileyo koko,I-SFF 8482intambo ezimbini kwi-1 igxila ngakumbi ekudibaneni okubonakalayo kunye nokuzinza kwentsebenziswano kweetshaneli ezimbini. Xa abasebenzisi bekhetha, ukuba imfuno igxile kuqhagamshelo oluthe ngqo lwezixhobo ze-PCIe ezicocekileyo, ke ngoko intambo ethembekileyoIntambo ye-Oculink SFF 8611 4Ilolona khetho luthe ngqo; ukuba kuyimfuneko ukuqhagamshela kwizixhobo ezixhotyisweI-MiniSAS HD (SFF-8643)amazibuko, emva kokoI-PCIE Oculink SFF 8611 4I to Intambo ye-SFF-8643kufuneka isetyenziswe.
Ukujonga phambili, ngokuqhubela phambili kwemigangatho ye-PCIe 5.0 kunye ne-6.0, iimfuno ze-bandwidth yekhebula kunye nokuthembeka kwesignali ziya kwanda ngokukhawuleza. Nokuba yindlela esisiseko yeIntambo ye-Oculink SFF 8611 4I, iI-SFF 8482ezimbini kwintambo enye edibanisa iitshaneli ezimbini, okanyeI-PCIE Oculink SFF 8611 4I to Intambo ye-SFF-8643Ukuba ithatha uxanduva lokuguqulwa kweprotocol, ukuphindaphinda kwayo kwezobuchwepheshe kuya kumisela ngokuthe ngqo amandla okwandiswa kwamaqonga ekhompyutha esizukulwana esilandelayo. Kunokubonwa kwangaphambili ukuba ezi ntambo zikhethekileyo ziya kuqhubeka nokudlala indima ebalulekileyo kumaziko edatha, kwiindawo zokusebenzela zobukrelekrele bokwenziwa, kunye neendawo zokubonisa imifanekiso eziphezulu, zixhasa ukuhamba kwedatha enkulu ngonxibelelwano oluchanekileyo lomzimba.
