25GbE NIC

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.
