Ukwandisa Amanani Edatha Ngokushintshaniswa kwe-PAM4
Ukuguqulwa kwe-PAM4 kudlala indima ebalulekile ekuthuthukisweni kokudluliselwa kwedatha ngesivinini esikhulu ngokufaka ikhodi kuma-bits amabili ngesimboli ngasinye ngamazinga amane ahlukene esignali. Le ndlela iphinda kabili izinga ledatha uma kuqhathaniswa nokubonakaliswa kwe-NRZ okuvamile, ngaphandle kokudinga i-bandwidth eyengeziwe—okwenza kube yisisombululo esisebenzayo se-400G Ethernet kanye nezindinganiso zesikhathi esizayo.
Ngokudlulisela idatha eyengeziwe ngaphakathi kobubanzi obufanayo be-spectral, i-PAM4 yandisa ukusebenza kahle kwe-spectral futhi inciphisa isidingo sezingxenye ezengeziwe ze-optical. Lokhu kuphumela ekongeni izindleko okukhulu kanye nokusebenza kahle kwamandla okuthuthukisiwe kumanethiwekhi asebenza kahle kakhulu.
Ukunika Amandla Amanethiwekhi Akwazi Ukukhula, Asebenza Kahle Kakhulu Ngezintambo ze-OSFP
Izintambo ze-OSFP ezisheshayo ziyisivikelo esibalulekile sokuxhumana okukhuliswayo nokusebenza kahle ezikhungweni zedatha zanamuhla. Umklamo wazo omncane usekela ukuminyana okukhulu kwe-port, wandisa isikhala esibalulekile se-rack. Uma zihlanganiswa ne-PAM4 signaling, ziqinisekisa ubuqotho besignali obuthembekile emabangeni amade, zinciphisa ukuncika ezingxenyeni ezisebenzayo.
Ihlanganiswe nomklamo wemishini oqinile futhi osebenziseka kalula, izinhlaka zekhebula ze-KEXINT OSFP ziletha ikhambi elivikela ikusasa lezikhungo zedatha ezidinga i-bandwidth ephezulu kanye nokuguquguquka okuguquguqukayo.
Amakhebula e-OSFP DAC okuxhumana kwe-400G okuSebenza kahle kakhulu
Lokhu kulungiselelwa kusungula isixhumanisi se-400G esinejubane eliphezulu, esiphansi phakathi kwamaseva amabili e-GPU, ngalinye lihlonyiswe nge-NVIDIA® ConnectX-7 NIC. Kusetshenziswa ikhebula le-Copper le-OSFP-to-OSFP Direct Attach (DAC) elisebenza kahle kakhulu elitholakala ngobude obusukela kumamitha angu-0.5 kuya kwangu-2—ukusethwa kunikeza i-bandwidth ephezulu kakhulu kanye nokubambezeleka okuncane okudingekayo emisebenzini ye-AI enamandla kanye ne-high-performance computing (HPC) ezindaweni ezixinene zesikhungo sedatha.
Ukwakha Amaqoqo angu-800G e-Quantum-2 InfiniBand nge-OSFP Cabling
Ukuze kuhlangatshezwane nezidingo ze-bandwidth ezidlulele zamaqoqo e-HPC ne-AI anamuhla, kunesethi yezixazululo zokuxhuma ze-800G OSFP ezakhiwe ngenhloso ezilungiselelwe ukushintsha kwe-NVIDIA Quantum-2 InfiniBand. Ukuxhuma kwethu izintambo kuqinisekisa ukuxhumana kwe-800G okungenamthungo, okubambezeleka okuphansi, kungaba ukuthunyelwa kwangaphakathi kwe-rack noma phakathi kwemigqa.
Ukuze uthole uxhumano olunobukhulu obuphezulu, oluthinta izindleko namandla olufinyelela kumamitha ama-3, izintambo zethu ze-Direct Attach Copper (DAC) zinikeza ukusebenza kahle okuphezulu. Ukuze uthole ukufinyelela okude kwamamitha angama-20 nangaphezulu ngaphandle kokuwohloka kwesiginali, izintambo zethu ze-Active Optical (AOC) zinikeza enye indlela eqinile. Zombili izixazululo zihambisana ngokugcwele nezixhumi ezimbili ze-OSFP, okuvumela ukukhuliswa kwe-plug-and-play kwengqalasizinda esheshisiwe nenkulu.
Ukuxhumeka kwe-Ultra-High-Density 1.6T kwezinhlelo zokusebenza ezifinyeleleka kalula
Ikhebula le-OSFP-1.6T linikeza isisombululo sokuxhumana esisebenza kahle kakhulu, esifinyeleleka kalula sokuxhumana okuqondile kokushintshela ...
