Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
Le KEXINT NVIDIA/Mellanox MMS4A00 ehambisanayo ne-1.6T OSFP224 2xDR4 Optical Transceiver Module imelela ubuchwepheshe obuphelele bokuxhumana kwesikhungo sedatha se-AI esinobukhulu obuphezulu. Inikwe amandla yi-Broadcom 3nm DSP (Sian3) yanamuhla kanye ne-8x200G PAM4 modulation ethuthukisiwe, inikeza i-passput yedatha ephansi engenakuqhathaniswa ngokusetshenziswa kwamandla okuphansi kakhulu.
Yakhelwe ngqo ama-InfiniBand XDR / Quantum-X800 Air-Cooled Switches esizukulwane esilandelayo, ukwakheka kokushisa okuhlanganisiwe kwe-Closed Finned Top (IHS) kuqinisekisa ukushabalaliswa kokushisa okuqinile ngaphansi kwemithwalo yekhompyutha eyingozi kakhulu, kususa izithiyo ze-I/O.
Ifaka phakathi i-Dual MPO-12/APC interfaces yokuxhumana okungaxhunyiwe kwe-1310nm 500m Single-Mode Fiber (SMF), le module yezinga lenkampani inikeza onjiniyela benethiwekhi ukuhambisana okuphelele okungu-100%, ukuzinza kwehadiwe okuqinile, kanye nokusebenza kahle kwe-ROI okuhle kakhulu kwekhompyutha ephezulu esebenza kahle (i-HPC) kanye namaqoqo amakhulu e-AI.
Incazelo Yomkhiqizo
I-NVIDIA/Mellanox MMS4A00 Iyahambisana ne-1.6T OSFP224 2xDR4/DR8 8x200G PAM4 InfiniBand XDR Optical Transceiver Module(SMF, 1310nm, 500m, Dual MPO-12/APC, DOM, IHS/Closed Finned Top)
I-NVIDIA/Mellanox MMS4A00 (980-9IAH1-00XM00) I-OSFP Optical Transceiver ehambisanayo iyimojula ye-OSFP IHS/Closed Finned Top enamachweba amabili enikeza amanethiwekhi e-InfiniBand XDR angu-2x 800Gb/s (1.6T). Iqukethe ukwakheka kwemodi eyodwa, okusekelwe ku-silicon photonics okuneziteshi eziyisishiyagalombili ezifanayo, okusekela ukudluliselwa kwe-2×DR4/DR8. Imbobo ngayinye ye-800G iphela ngesixhumi se-MPO-12/APC esineziteshi ezine. Imojula isebenzisa ukuguqulwa kukagesi kwe-200G-PAM4 futhi inikeza ukuxhumana okuthembekile okufushane okufika kumamitha angu-500 ngaphezu kwemicu eyisishiyagalombili yemodi eyodwa.
Yakhelwe nge-Broadcom 3nm DSP, le transceiver iqinisekisa amazinga amaphutha e-bit aphansi kakhulu kanye nokulethwa kwedatha okuzinzile, okusheshayo ekusetshenzisweni okuphezulu. Idizayini yayo ye-IHS/Closed Finned Top ivumela ukuphathwa okusebenzayo kokushisa kwamaswishi e-Quantum-X800, okusekela kokubili ukucushwa komoya kanye nokuphola koketshezi. Ihambisana kahle nezinhlelo ze-NVIDIA B300 kanye ne-DGX, le module inikeza ukuxhumana kwe-GPU-to-GPU kanye ne-GPU-to-storage okukalayo, okubambezeleka okuphansi, okulungele ukuxhumana kwe-AI, HPC, kanye nezindawo ezinkulu zokuxhumanisa izikhungo zedatha, ivula amandla aphelele ezindwangu zekhompyutha ezisebenza kahle kakhulu.
Qaphela: Ama-transceiver "aphezulu" manje abizwa ngokuthi "i-Integrated HeatSink" (IHS) njengoba ama-cooling fin ehlanganiswe ne-OSFP connector metal top. Avame ukusetshenziswa kuma-switch apholile emoyeni. Ama-transceiver "aphezulu" manje abizwa ngokuthi "i-Riding Heat Sink" (RHS) njengoba ama-cooling fin ehamba phezu kwekhadi lenethiwekhi noma ama-system internal cages. Lokhu kusetshenziselwa kokubili izinhlelo zokusebenza ezipholile emoyeni kanye nezipholile ngoketshezi ze-DGX, ConnectX-7, kanye ne-BlueField-3 DPUS.
