Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
I-NVIDIA ConnectX-7 MCX75310AAS-NEAT iyi-adaptha yenethiwekhi yesimanje engu-400Gb/s eyenzelwe ngqo inkathi ye-exascale kanye nemithwalo yemisebenzi edinga kakhulu eqhutshwa yi-AI. Inechweba elilodwa le-OSFP, inikeza ukuguquguquka okungenakuqhathaniswa ngokusekela kokubili amaphrothokholi e-NDR InfiniBand kanye ne-400GbE ngokusebenzisa ubuchwepheshe be-Virtual Protocol Interconnect (VPI) obuphambili be-NVIDIA.
Njengesizukulwane sokuqala ukusebenzisa ngokugcwele i-interface ye-PCIe 5.0 x16, le adaptha iphinda kabili ukudluliselwa kwedatha ku-host, isusa izithiyo ze-I/O ezivame ukuphazamisa ukusebenza kwe-high-performance computing (HPC) kanye ne-hyperscale cloud environments. Ngaphandle kwesivinini esiluhlaza, i-MCX75310AAS-NEAT yakhelwe phezu komklamo "wokuphepha kuqala" one-Secure Boot kanye nezinjini ezithuthukisiwe ezisheshiswa yihadiwe. Lezi zinjini zilayisha imisebenzi eyinkimbinkimbi yokuxhumana, isitoreji, kanye nokuphepha kusuka ku-CPU, okuholela ekusebenzeni kahle kwesistimu okuphezulu, ukubambezeleka okuphansi kakhulu, kanye nokuvikelwa kwedatha okuthuthukisiwe. Kuyisinqumo esiqinisekile samabhizinisi afuna ukwakha ingqalasizinda yekhompyutha ephephile, evikela ikusasa, kanye neyobuningi obukhulu.

Izixazululo Zokuxhumana
Izici
Isixazululo se-RDMA esiphelele phezu kwe-Converged Ethernet (RoCE)
I-ConnectX-7 NIC inikeza i-RDMA ephezulu kakhulu ngaphezu kwamakhono e-Converged Ethernet (RoCE) futhi ivumela ukuxhumana kwe-RoCE okubambezeleka okuphansi, okungalahleki kwamaqoqo e-AI ne-HPC angalinganiswa, ngokufakwa okulula nokusebenza.
I-adaptha ye-Single-Port Esekela i-InfiniBand ne-Ethernet engu-400Gb/s
Ama-ConnectX-7 NIC ahlinzeka ngezixazululo zokuxhumana ezithuthukisiwe, ezingalinganiswa, neziphephile ze-AI edingekayo, ikhompyutha yesayensi, kanye nomsebenzi wefu ophakeme, oletha isivinini esifinyelela ku-400 Gb/s.
Vula Ukusebenza Kwenethiwekhi Okungenamthungo Nokuhlolwa Kokuhambisana
Ngezinqubo zokuhlola eziphelele, siqinisekisa ukuhambisana okungenamthungo namaseva ajwayelekile, okuqinisekisa ukuthembeka kwesikhathi eside kanye nokuzinza kwengqalasizinda yonke yenethiwekhi.
Ukuxhumana Okuthuthukisiwe Nokuphepha
Isekela i-SR-IOV kanye ne-VirtIO hardware virtualization, ithuthukise ukusebenza, ilayisha umthwalo wemisebenzi yenethiwekhi yamafu, ikhulule ama-CPU cores, futhi inciphise izindleko eziphelele zobunikazi.
Imibuzo Nezimpendulo
U: Yini engingayifeza ngokuphatha ama-NIC e-NVIDIA kanye ne-Broadcom nge-AmpCon?
A: I-AmpCon ivumela ukuphathwa okuhlangene kanye nokuqapha ohlangothini lwe-host kanye nolwenethiwekhi kuyo yonke indwangu yakho yesikhungo sedatha, okwenza kube lula ukusebenza ezindaweni ze-NIC zabathengisi abaningi. Ihambisa kalula ukuthunyelwa kwe-RoCE, ikuvumela ukuthi ucindezele izikripthi ze-RoCE ezijwayelekile noma amapharamitha enziwe ngokwezifiso, njenge-PFC, i-ECN, kanye ne-DSCP, kumadivayisi amaningi ngokuchofoza okumbalwa nje. Uma isisetshenzisiwe, i-AmpCon inikeza ukubonakala kwesikhathi sangempela kuthrafikhi ye-RoCE kuzo zombili izishintshi kanye nama-NIC, kufaka phakathi ozimele bokumiswa kwe-PFC, izimpawu ze-ECN, kanye nezibalo zokuminyana komugqa. Lokhu kubonakala ohlangothini lwe-host kanye nolwenethiwekhi kukusiza ukuthi ubone ngokushesha izithiyo zokusebenza futhi uthuthukise inethiwekhi yakho ngenkuthalo ukuze uthole umthwalo wemisebenzi ophezulu, we-AI ephansi kanye ne-HPC.
U: Yimuphi umehluko phakathi kwamamojula esibonakalayo se-OSFP ohlangothini lwekhadi lenethiwekhi kanye nohlangothi lokushintsha?
A: Uhlangothi lokushintsha lusebenzisa amamojula e-OSFP acwebezelayo ane-convection yomoya, amafeni akhelwe ngaphakathi, kanye nama-heatsink afakwe ezidingweni zokushisa ezinamandla aphezulu/eziphezulu; uhlangothi lwe-NIC lusebenzisa amamojula e-OSFP acwebezelayo ukuze kube nezikhala ezincane, ezithembele kumafeni angaphandle/ukupholisa uketshezi. Isibonelo, uma usebenzisa i-800G IB Switch to 2x 400G OSFP NIC with Modules, sebenzisa imojula ye-800G Finned Top OSFP #205113 ohlangothini lokushintsha kanye nemojula ye-400G Flat Top OSFP #200963 ohlangothini lwe-nic.
Q: Ungayisetha kanjani i-MCX75310AAS-NEAT Single-port OSFP njengamachweba amane ahlukene?
A: Ikhadi lenethiwekhi le-MCX75310AAS-NEAT alikwazi ukuhlukaniswa libe amachweba amane e-100G; lo msebenzi awusekelwa. Kuma-NVIDIA NIC adinga ukusebenza kokuhlukaniswa kwamachweba, sincoma ukukhetha imikhiqizo yochungechunge lwe-CX8 etholakalayo. Isibonelo, i-C8180 900-9X81E-00EX-ST0 isekela ukuhlukaniswa kube amachweba afinyelela ku-8 e-100G. Ukuze ufinyelele ukuxhumana okuqondile kwe-100G, cabanga ngama-100G NVIDIA NIC njenge-MCX623106AN-CDAT.
U: Ingabe le adaptha yenethiwekhi ingasetshenziswa ne-transceiver efakwe i-top enezinti?
A: Cha, akunakwenzeka. I-NIC iyahambisana nemodyuli efakwe ingaphezulu eliyisicaba, kuyilapho amamojula anezingcezu ezigobile eklanyelwe ukusetshenziswa namaswishi.
