Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
I-adaptha ye-NVIDIA Mellanox MCX653105A-HDAT ConnectX-6 HDR 200G InfiniBand iyisisombululo sokuxhumana esihamba phambili esenzelwe ngqo izikhungo zedatha ze-AI zesimanje, izindawo zamafu ezisezingeni eliphezulu, kanye ne-High-Performance Computing (HPC). Ihlinzeka nge-throughput ye-single-port evuthayo engu-200Gb/s, le adaptha isebenzisa isikhombimsebenzisi se-PCIe 4.0 x16 esithuthukisiwe (esihambisana ne-PCIe 3.0) ukuze kuqedwe izithiyo zokudlulisa idatha futhi kwandiswe ukusebenza kohlelo lonke.
Iqukethe ukubambezeleka kwe-microsecond ephansi kakhulu, okungaphansi kwe-0.6 kanye nokusekelwa okuqinile kobuchwepheshe be-RDMA, GPUDirect, kanye ne-In-Network Computing, ikhipha imisebenzi ye-CPU kakhulu ukuze isheshise ukusebenza kahle kokucubungula okuhambisanayo. Kungakhathaliseki ukuthi isetshenziselwa ukuqeqeshwa kokufunda okujulile okuyinkimbinkimbi noma ukulingisa okukhulu kwesayensi, i-MCX653105A-HDAT iqinisekisa ukuzinza okuqinile kanye nokukhula okuqondile okungenamthungo. Ihlonyiswe nge-Tall kanye ne-Short Brackets, ihlanganiswa kalula ne-chassis yeseva ehlukahlukene ejwayelekile nephansi, inikeza isisekelo esifanele sokwakha ingqalasizinda yekhompyutha yesizukulwane esilandelayo, esebenza kahle kakhulu.
Incazelo Yomkhiqizo
Ikhadi le-NVIDIA Mellanox MCX653105A-HDAT ConnectX-6 Virtual Protocol Interconnect (VPI) liyisengezo esiphambili ochungechungeni lwe-ConnectX oluhamba phambili embonini. Lakhelwe ukuhlangabezana nezidingo eziphuthumayo zezikhungo zedatha zanamuhla, le adaptha inikeza imbobo eyodwa yokuxhumana kwe-HDR 200Gb/s InfiniBand kanye ne-200GbE Ethernet. Ngokuletha ukubambezeleka kwe-sub-0.6 microsecond (600ns) kanye nemiyalezo emangalisayo eyizigidi ezingu-215 ngomzuzwana, linikeza isisombululo sokusebenza okuphezulu kakhulu kanye nesisombululo sokuxhumana esiguquguqukayo kakhulu esitholakalayo semisebenzi yokusebenza ephezulu (HPC) kanye ne-AI.
Okuvelele komkhiqizo
1. Umthamo Ophakeme Kakhulu we-200Gb/s Uhlinzeka nge-bandwidth egqamile ye-200Gb/s nge-HDR InfiniBand kanye ne-200GbE Ethernet, okunikeza umthamo omkhulu wedatha odingekayo ezindaweni ze-AI kanye ne-high-performance computing (HPC).
2. Ukusebenza Kokubambezeleka Okuphansi Kakhulu: Kufinyelela ukubambezeleka okungaphansi kwe-0.6 microsecond (600ns), okuqinisekisa ukudluliswa kwedatha okucishe kube ngokushesha okubalulekile ezinhlelweni zokusebenza zesikhathi sangempela kanye nemithwalo yemisebenzi evame kakhulu.
3. Ukuxhumana Okuthuthukisiwe kwe-PCIe 4.0: Kufaka isikhombimsebenzisi se-PCIe 4.0 x16 host ukuze siphindwe kabili i-bandwidth etholakalayo uma kuqhathaniswa ne-PCIe 3.0, sisuse izithiyo ze-CPU-to-network futhi sithuthukise ukusebenza kwe-GPU.
4. Ubuchwepheshe be-VPI™ obuguquguqukayo busebenzisa i-Virtual Protocol Interconnect (VPI) ukuze isebenze kahle ezindaweni ze-InfiniBand noma ze-Ethernet, okunikeza ukuguquguquka okungenakuqhathaniswa kanye nokuvikelwa kokutshalwa kwezimali kwengqalasizinda eshintshashintshayo.
5. I-Smart AI kanye ne-Computing Offloads zisekela i-RDMA, i-GPUDirect, kanye ne-NVIDIA SHARP™ (In-Network Computing) ukuze zikhiphe idatha ekucutshungulweni kwe-CPU, okwandisa kakhulu ukusebenza kahle kokufunda komshini kanye nesivinini sokubala esihambisanayo.
6. Ukuhlanganiswa Kwe-Chassis Eguquguqukayo: Ifakwe ama-Bracket Amade nama-Short, okuvumela ikhadi le-QSFP56 elinembobo eyodwa ukuthi lilingane kahle ne-chassis yeseva ejwayelekile noma ephansi (1U/2U) .
Izici
Ukulayisha Okuhlakaniphile Nokusebenza Kahle: I-ConnectX-6 isebenzisa ubuchwepheshe be-In-Network Computing obuphambili (i-NVIDIA SHARP™) ukulayisha imisebenzi yokuhlanganisa idatha nokunciphisa kunethiwekhi, okusheshisa kakhulu izinhlaka ze-MPI kanye nokufunda komshini.
I-PCIe 4.0 Ilungile: Isekela isikhombimsebenzisi sakamuva se-PCIe 4.0 x16 host (ngenkathi igcina ukuhambisana okugcwele emuva ne-PCIe 3.0), i-MCX653105A-HDAT iphinda kabili i-bandwidth etholakalayo ku-CPU, iqinisekisa ukuthi akukho mingcele yokudluliselwa kwedatha okusheshayo.
Ubuchwepheshe be-VPI (i-Virtual Protocol Interconnect): Ngokungafani nama-NIC ajwayelekile, leli khadi line-VPI, elivumela ukuthi lisebenze kahle ezindaweni ze-InfiniBand noma ze-Ethernet. Lokhu kuguquguquka kuvikela utshalomali lwakho futhi kwenza kube lula ukufuduka kwengqalasizinda.
I-RDMA Ethuthukisiwe kanye ne-GPUDirect: Ukusekelwa okuthuthukisiwe kwe-RDMA (Remote Direct Memory Access) kanye ne-GPUDirect kuqinisekisa ukushintshaniswa kwedatha okuqondile phakathi kwememori ye-GPU kanye nenethiwekhi, okunciphisa kakhulu izindleko ze-CPU emisebenzini yokufunda okujulile.
Isici Sefomu Esiguquguqukayo
I-adaptha ithunyelwa ngendlela eqhubekayo ngama-Bracket Amade nama-Short (Ajwayelekile kanye nama-Low-Profile), okuqinisekisa ukuhambisana nohlu olubanzi lwe-chassis yeseva—kusukela kuma-rackmount ebanga lebhizinisi angu-4U kuya kumaseva ama-blade angu-1U/2U anabantu abaningi.
