Ukuqonda lezi zintambo ezintathu Yimuphi umehluko phakathi kwe-SFF 8482,I-Oculink SFF 8611 kanye ne-SFF-8643？
Emkhakheni wokudlulisa idatha ngesivinini esikhulu kanye nokuxhumana okude, izintambo zobungcweti zisebenza njengamabhuloho abalulekile okufeza impumelelo yokusebenza. Phakathi kwazo,I-SFF 8482ezimbili kukhebula elilodwa,I-PCIE Oculink SFF 8611 4I to Ikhebula le-SFF-8643, kanyeIkhebula le-Oculink SFF 8611 4IAma-e ahamba phambili ngemiklamo yawo enembile kanye nokusebenza okuhle kakhulu, edlula imingcele yezinhlelo zokusebenza kusukela kusitoreji sezinga lebhizinisi kuya kwikhompyutha esebenza kahle kakhulu.
Okokuqala, ake sigxile ku-I-SFF 8482ikhebula elibili kwelinye, elimele ukudluliswa okuhlanganisiwe kweziteshi eziningi. Le khebula ihlanganisa ngobuhlakani iziteshi ezimbili zibe yinye, esetshenziswa kabanzi ezimweni ezidinga ukudluliswa okuhambisanayo kwe-bandwidth ephezulu. Uma kuqhathaniswa nokufanayoI-SFF 8482izintambo ezimbili kwelinye,Ikhebula le-Oculink SFF 8611 4I, eyenzelwe ngqo ukunwetshwa kwesiteshi se-PCIe, ihloselwe kakhulu. Njengelungu eliyinhloko lomndeni we-Oculink (Optical Copper Link), indinganiso ngayinyeIkhebula le-Oculink SFF 8611 4Iifaka amabhangqa amane azimele ahlukene ngesivinini esikhulu, okuqinisekisa ukudluliselwa kwezimpawu ze-PCIe ngokulahlekelwa okuphansi kanye nokubambezeleka okuphansi.
Kodwa-ke, ekuhlanganisweni kwesistimu yangempela, ukuhlukahluka kwezixhumi zedivayisi kuvame ukudinga izixazululo zokuguqula eziguquguqukayo. Yilapho-keI-PCIE Oculink SFF 8611 4I toIkhebula le-SFF-8643iyazimela. Lokhu okukhethekileI-PCIE Oculink SFF 8611 4I to Ikhebula le-SFF-8643ine-interface encane ye-Oculink ngakolunye uhlangothi kanye ne-I-SFF-8643isikhombikubona, esivame ukutholakala kuma-SAS expanders kanye nama-backplanes, ngakolunye uhlangothi. Sixhumanisa iphrothokholi ye-PCIe nemvelo ye-SAS, sithuthukisa kakhulu ukuguquguquka kokucushwa kwesistimu. Kungakhathaliseki ukuthi ukuxhuma ama-GPU docks angaphandle noma ama-array esitoreji asheshayo, ukukhetha okulungileI-PCIE Oculink SFF 8611 4I to Ikhebula le-SFF-8643kubalulekile.
Ngokombono ongokwenyama, ikhwalithi ephezuluIkhebula le-Oculink SFF 8611 4Iinezidingo eziqinile zobuchwepheshe bokuvikela kanye nokulawula i-impedance ukuphatha amasignali esivinini esiphezulu se-GHz. Ngokuphambene nalokho, i-I-SFF 8482ikhebula le-two in one ligxila kakhulu ekuhlanganisweni okungokoqobo kanye nokuzinza kokubambisana kweziteshi ezimbili. Uma abasebenzisi bekhetha, uma isidingo sigxile ekuxhumekeni okuqondile kwamadivayisi e-PCIe ahlanzekile, khona-ke ikhebula elithembekileIkhebula le-Oculink SFF 8611 4Ikuyisinqumo esiqondile kakhulu; uma kudingeka ukuxhuma kumadivayisi afakweI-MiniSAS HD (SFF-8643)amachweba, bese kubaI-PCIE Oculink SFF 8611 4I to Ikhebula le-SFF-8643kumele kusetshenziswe.
Uma sibheka phambili, ngokuthuthuka kwezindinganiso ze-PCIe 5.0 ngisho nezinga le-6.0, izidingo ze-bandwidth yekhebula kanye nobuqotho besiginali zizokhula ngokushesha. Kungakhathaliseki ukuthi kuyindlela eyisisekelo ye-Ikhebula le-Oculink SFF 8611 4I, iI-SFF 8482ikhebula elibili kwelinye elihlanganisa iziteshi ezimbili, nomaI-PCIE Oculink SFF 8611 4I to Ikhebula le-SFF-8643Njengoba ithatha umthwalo wemfanelo wokuguqulwa kwephrothokholi, ukuphindaphinda kwayo kobuchwepheshe kuzonquma ngqo amandla okukhula kwamapulatifomu ekhompyutha esizukulwane esilandelayo. Kungabonwa kusengaphambili ukuthi lawa makhebula akhethekile kakhulu azoqhubeka nokudlala indima ebalulekile ezikhungweni zedatha, ezindaweni zokusebenza zobuhlakani bokwenziwa, kanye nezinkambu zokunikeza izithombe eziphezulu, ukusekela ukugeleza kwedatha okukhulu ngokuxhumana okuqondile ngokomzimba.
