Ukuxhumana Kwesikhungo Sedatha se-AI

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.

I-KEXINT iveza i-NVIDIA Mellanox ConnectX-8 (CX8) VPI Adapter (P/N: 900-9X81E-00EX-ST0), ubuchwepheshe obuphezulu be-interface yenethiwekhi eklanyelwe ukunika amandla isizukulwane esilandelayo samaqoqo e-AI, ingqalasizinda yamafu e-hyperscale, kanye nezindawo ze-High-Performance Computing (HPC). Njengesinyathelo esiqhubekela phambili ekuxhumaneni, le adaptha iletha i-throughput ye-800GbE XDR engakaze ibonwe ngaphambili ngesixhumi esibonakalayo se-OSFP esinekheji elilodwa, ngenkathi isekela ukucushwa okuguquguqukayo njenge-2 x 400GbE yokusetshenziswa okuguquguqukayo. Yakhelwe phezu kwendinganiso ye-PCIe 6.0 x16 yanamuhla, inikeza i-bandwidth ephindwe kabili yezizukulwane ezedlule, iqinisekisa ukugeleza kwedatha okungenamkhawulo phakathi kwe-CPU nenethiwekhi. Umehluko obalulekile ubuchwepheshe be-Socket-Direct, obuthuthukisa ukwabiwa kwezinsizakusebenza zehadiwe ukuze kufezwe ukubambezeleka okuphansi kakhulu—isidingo esibalulekile sokuqeqeshwa kwe-AI evumelanisiwe kanye nezinhlelo zokusebenza zezimali ezivame kakhulu. Ukuphepha kuyisisekelo somklamo we-ConnectX-8, oqukethe izinjini ze-Hardware Crypto ezihlanganisiwe kanye ne-Secure Boot ukuvikela ubuqotho bedatha nokuvimbela ukufinyelela kwe-firmware okungagunyaziwe. Ukuze kuhambisane kahle kakhulu nehadiwe, i-KEXINT inikeza amabhuleki amade namafushane, okuvumela ukuhlanganiswa okungenamthungo kumaseva ahlukahlukene e-rack aphezulu. Ngokukhetha i-ConnectX-8, uhlomisa ingqalasizinda yakho ngokusebenza okuthuthuke kakhulu embonini, ukuphepha, kanye nokukhula kwesikhathi esiqhutshwa yi-AI.

I-KEXINT MCX4121A-ACAT iyikhadi le-25GbE Dual-Port SFP28 Network Interface Card (NIC) elisebenza kahle kakhulu elenzelwe izikhungo zedatha ze-AI zesimanje, ingqalasizinda yamafu, kanye nezindawo ezisebenza ngobuningi obukhulu. Yakhelwe phezu kwesilawuli sokuqala se-NVIDIA Mellanox ConnectX-4 Lx, le adaptha inikeza umkhawulokudonsa ophindwe izikhathi ezingu-2.5 wamanethiwekhi e-10G ngenkathi igcina amandla afanayo, inikeza indlela ye-ROI engabizi kakhulu yamabhizinisi ashintsha kusuka ku-10G kuya ku-25G architectures. Inzuzo yayo eyinhloko isekusekelweni okuphelele kwe-RoCE (RDMA phezu kwe-Converged Ethernet), iletha ukubambezeleka kwe-sub-microsecond futhi ithuthukise kakhulu ukusebenza kahle kwe-NVMe-over-Fabrics (NVMe-oF) storage kanye ne-high-performance computing (HPC) clusters. Ngaphezu kwalokho, ngokuhlanganisa izinjini zokulayisha ihadiwe ezithuthukisiwe—kufaka phakathi i-VXLAN, i-NVGRE, kanye ne-Geneve—inciphisa ngempumelelo i-CPU overhead, iqinisekise ukusebenza kahle kwesistimu ngisho nangaphansi kwethrafikhi enkulu yenethiwekhi. Ifakwe i-bracket ejwayelekile engu-4.72 in (120mm) ubude, ikhadi linamathela ngokuqinile ezindinganisweni zobunjiniyela zase-US kanye nokufakwa kwamanye amazwe, okwenza kube ukukhetha okuthandwayo kwabakhi be-IT kanye nabahlanganisi bezinhlelo abafuna ukusebenza okuphezulu kwe-I/O kanye nokuthembeka kwesikhathi eside.

Nika amandla umgogodla wesikhungo sakho sedatha ngekhebula le-MMC-16 Trunk le-KEXINT elinobukhulu obuphezulu, isisombululo sokuxhumana kwefayibha esiphambili esenzelwe ingqalasizinda yokuxhumana ye-800G ne-1.6T. Isekela umthamo omkhulu kusukela kumafayibha angu-16 kuya kwangu-384, le khebula inesixhumi se-MMC sesizukulwane esilandelayo se-VSFF (Very Small Form Factor) se-MMC, esivumela ukuminyana kwe-port okungakaze kubonwe ngaphambili kanye nokuphathwa kwekhebula okulula kumaqoqo e-AI asebenza kahle kakhulu. Yakhiwe nge-fiber ye-OS2 Single-Mode ye-premium, ifinyelela ukusebenza kwe-Elite 0.35dB Max okuphansi kakhulu kokulahlekelwa ukuqinisekisa ubuqotho besignali obuphezulu emabangeni amade. Ukwakhiwa kwe-Double Jacket okuqinile kunikeza ukuvikelwa okuthuthukisiwe komshini kanye nokuqina komzila wangaphakathi oyinkimbinkimbi. Yakhelwe ukuthembeka nokukhula, le ntambo ye-trunk ye-MMC-16 iyisinqumo esihle kakhulu sezixhumanisi zomgogodla ze-bandwidth ephezulu, iletha ukuzinza okubalulekile okudingekayo ezikhungweni zedatha ze-AI zanamuhla kanye ne-hyperscale.
