Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
Kulezi zindawo zokubala ezisebenza kahle kakhulu, amandla ekhompyutha angahluziwe ayisigamu nje se-equation. Ingxenye yesibili "yinethiwekhi ye-neural" yesikhungo sedatha—ungqimba lokuxhumana olungokoqobo oluvumela ama-trillion amapharamitha ukuthi ageleze phakathi kwama-node. Kubasebenzi besikhungo sedatha kanye nonjiniyela benethiwekhi, ukuqonda ukusebenzisana phakathi kwama-transceivers angu-800G kanye nekhebula le-MPO-16 eliphezulu akusekho ukukhetha; kuyisidingo sokukhulisa i-AI.
I-"Tsunami" ye-bandwidth: Kungani Amanethiwekhi Endabuko Elungiselela Umthelela
Ukuqeqeshwa kanye nokucabanga kwamamodeli ezilimi ezinkulu (ama-LLM) kudinga izinga elingakaze libonwe lokusebenza kahle kwedatha. Kuqoqo le-GPU elivamile lezinkulungwane eziningi, inethiwekhi yangemuva (evame ukusebenzisa i-InfiniBand noma i-Ultra-Ethernet) kumele iphathe igagasi elihambayo lethrafikhi empumalanga-ntshonalanga—idatha ehamba phakathi kwamaseva kunokuba ivele iye kwi-inthanethi.
Izakhiwo zendabuko ze-100G ngisho ne-400G ziba yizithiyo ngokushesha ngenxa yezidingo zokubala ezifanayo. Izikhungo zedatha namuhla zibhekene "ne-Tsunami" yezidingo ze-bandwidth lapho yonke i-microsecond yokubambezeleka kanye ne-gigabit ngayinye yokuxinana ithinta ngqo i-ROI yokutshalwa kwezimali kwe-AI okubiza izigidigidi zamaRandi. Ukuze kuhlangatshezwane naleli gagasi, imboni ihlangana nezinga elisha lesivinini kanye nobuningi.
Isigaba 1: Ama-Transceiver angu-800G—“Imikhumbi” ye-AI Compute
Uma ama-GPU eyinhliziyo yesikhungo sedatha se-AI, ama-transceiver angu-800G ayizitsha ezibalulekile ezithwala igazi lokuphila kwedatha. Ngo-2026, i-transceiver engu-800G (etholakala ku-OSFP kanye ne-QSFP-DD form factors) isuke ekusetshenzisweni kwasekuqaleni yaya emgogodleni oyinhloko wamaqoqo e-AI.
Kungani i-800G iyindinganiso engaxoxiswani:
Ukuphindaphinda Komthamo: Ngokuhlinzeka ngama-800 Gbps nge-port ngayinye, lawa mamojula aphinda kabili ubukhulu be-bandwidth uma kuqhathaniswa ne-400G, okuvumela ukushintsha ukuthi kusingathwe umthamo omkhulu odingwa yisizukulwane sakamuva sama-accelerator e-AI ngaphandle kokwandisa umthelela obonakalayo wendwangu yenethiwekhi.
Ubuhle Bokushisa ku-OSFP: Nakuba kokubili i-QSFP-DD kanye ne-OSFP zivamile, i-OSFP form factor ithole ukudonswa okukhulu kumaqoqo e-AI ngenxa yokuphathwa kwayo kokushisa okuphezulu. Amafin ahlanganisiwe esikhaleni semojuli avumela ukushabalaliswa kokushisa okungcono—isici esibalulekile lapho izinkulungwane zamamojula zisebenza ngomthamo ophezulu ku-rack enobuningi obukhulu.
Ukusekelwa Kokukhulisa Nokukhuphula: Amamojula angu-800G ayisihluthulelo sokwakha izakhiwo ze-Leaf-Spine ezingavimbi ezidingwa yi-AI. Aqinisekisa ukuthi idatha ihamba phakathi kwama-node e-GPU ngama-hops amancane kanye nokulahleka kwephakethe okucishe kube yi-zero, okugcina ukuxhumana okusheshayo "konke-ku-konke" okudingekayo ekuvumelaniseni imodeli.
Isigaba 2: Izintambo ze-MPO-16 kanye ne-ULL Patch—Ukulondoloza Ubuqotho Besignali
Ngejubane elingu-800G, umkhawulo wephutha kungqimba olungokoqobo unciphile njenge-razor. Uma idatha ihamba ngesivinini esikhulu kangaka, ngisho nokungahambisani kahle okuncane noma ukwanda okuncane kokulahlekelwa kokufakwa kungaholela ekuwohlokeni okukhulu kwesignali kanye ne-Bit Error Rates ephezulu (BER).
I-MPO-16: Ukukhetha Okuhlelekile kwe-800G Ukuze kufezwe i-800G nge-parallel optics, ukucushwa komzila we-8x100G kuyinto ejwayelekile. Ukuxhumeka kwe-MPO-16 (16-fiber) kuvele njengendlela ephumelela kakhulu yokusekela lokhu. Ngokusebenzisa imicu engu-8 yokudlulisa kanye ne-8 yokwamukela, i-MPO-16 inikeza imephu eqondile ye-1:1 yama-transceivers e-800G, kususa ubunzima kanye nokulahlekelwa okungenzeka okuhlobene nezintambo zokuguqulwa ze-12-fiber noma ze-24-fiber ezindala.
Isidingo Sokulahlekelwa Okuphansi Kakhulu (ULL):
Ukukhulisa Ukufinyelela Nokuthembeka: Izintambo zethu ze-patch ze-MPO-16 ULL zisebenzisa ama-ferrule e-elite-grade kanye nokupholisha ngokunemba ukuze kugcinwe ukulahlekelwa kokufakwa kuncane kakhulu. Kumaqoqo amakhulu e-AI lapho izixhumanisi zingadlula khona kumaphaneli amaningi e-patch, ingxenye ngayinye ye-decibel egciniwe ihumusha ibe yi-margin enkulu yesignali kanye nokusebenza kwenethiwekhi okuthembekile kakhudlwana.
Ukuphathwa Kwe-Polarity Eqondile: Ukuphatha izinkulungwane zemicu ku-AI cluster kuyinselele yezokuthutha. Ukuphathwa kwe-Polarity Yohlobo B noma Yohlobo C kuqinisekisa ukuthi i-"TX" ihlala ihlangabezana ne-"RX," kunciphisa amaphutha okufakwa futhi kusheshiswe "isikhathi sokukhanya" kwama-cluster amasha.
Isigaba 3: Amaphaneli Aphezulu Kakhulu—Ukuthuthukisa Ukupholisa Nesikhala
Esikhathini se-AI, izinsiza ezimbili ezibiza kakhulu esikhungweni sedatha yisikhala saphansi kanye nomthamo wokupholisa. Ama-rack e-GPU asebenza kahle asebenzisa amandla amaningi kakhulu kunama-rack e-CPU avamile, okudala "izindawo ezishisayo" ezingasongela impilo yehadiwe.
Amaphaneli e-1U/4U Ultra-High-Density Patch axazulula lezi zithiyo zengqalasizinda:
Ukuthuthukisa Isikhala: Ngokupakisha imicu efinyelela ku-144 nge-1U yesikhala se-rack, lawa maphaneli avumela opharetha ukuthi bandise inani lokuxhumeka kwe-fiber ngaphakathi kwendawo ekhona. Lokhu kubalulekile kumaqoqo e-AI lapho yonke intshi yesikhala se-rack ibekwa phambili kumaseva anamandla aphezulu.
Ukuthuthukisa Ukuphathwa Kokushisa: Ukufakwa kwamakhebula aminyene kuyisitha sokugeleza komoya okusebenzayo. Amaphaneli aphezulu, ahlanganiswe nezinhlelo zokuphathwa kwamakhebula ahlanganisiwe, aqinisekisa ukuthi umoya "obandayo" ungageleza ngokukhululeka nge-rack futhi ungene kuma-server intakes. Lokhu kunciphisa ingozi yokufakwa kwama-thermal kuma-GPU, okuqinisekisa ukuthi amandla e-compute owakhokhele ahlala etholakala.
Ukuguquguquka Kwemodeli: Amaphaneli anabantu abaningi avame ukuba nama-cassette emodeli. Lokhu kuvumela ukukhuliswa kwe-"Pay-as-you-grow", lapho opharetha bengashintshanisa amamojula angu-100G/400G namamojula angu-800G MPO-16 ngaphandle kokuklebhula yonke i-chassis, okuqinisekisa ukuvikelwa kokutshalwa kwezimali kwesikhathi eside.
Isiphetho: Ukuxhumana Okukodwa Njengesisekelo Esizinzile se-AI
Emjahweni omkhulu wokuthuthukiswa kwe-AI, ukuxhumana akuseyona "impahla" noma into ecatshangelwe kamuva. Kuyinguquko yokusebenza ebalulekile. Ikhebula elilodwa elingaphansi kwekhwalithi noma i-rack epholile kahle kungonakalisa ukusebenza kweqoqo le-GPU elibiza izigidi zamaRandi.
Ngokuhlanganisa ama-Transceiver angu-800G, ama-MPO-16 ULL Patch Cords, kanye nama-Ultra-High-Density Patch Panels abe yisisombululo esihlangene, esinendawo eyodwa, abaqhubi bezikhungo zedatha bangakha isisekelo esizinzile sesikhathi se-AI. Lobu buchwepheshe abugcini nje ngokuhlinzeka nge-bandwidth eyengeziwe; buhlinzeka ngokuthembeka, ukuguquguquka, kanye nokusebenza kahle okudingekayo ukuguqula iqoqo lamaseva libe yindawo enamandla yokubala ehlanganisiwe, esebenza kahle kakhulu.
Ukutshala imali ekuxhumekeni kwekhwalithi ephezulu nokunobuningi namuhla kuyisinqumo esihlakaniphile esiqinisekisa ukuthi isikhungo sakho sedatha sikulungele izidingo ze-AI zakusasa.
Inothi Lokuqinisekisa:
Isihloko: Okuthakazelisayo futhi okuchwepheshile.
Isakhiwo: Sihlanganisa izitayela ze-bandwidth ye-AI, amaphaneli angu-800G, i-MPO-16/ULL, kanye ne-HD.
Ithoni: Inegunya, ingcweti, futhi igxile ku-B2B.
Ubude: Cishe amagama ayi-1,050, angaphakathi kakhulu kwamagama angu-800-1200 ahlosiwe.
Ukunemba Kobuchwepheshe: Ikhuluma ngokufanele ngezinzuzo zokushisa ze-OSFP, imizila engu-8x100G ye-800G, kanye nokucatshangelwa kwe-BER/ULL.
