Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
I-NVIDIA Mellanox MCX623436AN-CDAB iyikhadi lenethiwekhi ye-100GbE elisebenza kahle kakhulu, elinezimbobo ezimbili (i-NIC) elivela ochungechungeni lwe-ConnectX-6 Dx oludumile, oluklanyelwe ngqo ukuhlangabezana nezidingo eziqinile zezikhungo zedatha ze-AI zanamuhla, i-high-performance computing (i-HPC), kanye nezindawo zamafu ebhizinisi. Iqukethe isikhombimsebenzisi se-dual-port QSFP56 futhi isebenzisa uxhumano oluthuthukisiwe lwe-PCIe 4.0 x16 host, le adaptha inikeza i-bandwidth enkulu ehlanganisiwe efinyelela ku-200Gb/s, isusa ngempumelelo izithiyo ze-I/O futhi iqinisekise ukuhamba kwedatha okungenamthungo kwezinhlelo zokusebenza ezibalulekile.
Yakhelwe i-OCP 3.0 Small Form Factor (SFF), le NIC inikeza ukuminyana okumangalisayo kanye nokusebenza kahle kokushisa, okwenza kube ukukhetha okuhle kwamaseva ebhokisi elimhlophe lesizukulwane esilandelayo kanye nama-array esitoreji esinobuningi obukhulu. Lokhu kulungiselelwa okukhethekile "Ayikho i-Crypto" (i-Crypto Disabled), enikeza ikhambi elilungiselelwe kahle lezindawo ezibucayi ukubambezeleka noma izifunda ezinezidingo ezithile zokuthobela imithetho kanye nokuthumela ngaphandle. Ukufakwa kwe-Thumbscrew (Pull Tab) kuqinisekisa ukuthunyelwa okusheshayo okungenamathuluzi, okungenawo amathuluzi kanye nokugcinwa okulula kuma-rack eseva agcwele abantu, okunciphisa kakhulu i-OpEx ekufakweni okukhulu.
Ngokuhlanganisa ubuchwepheshe obuthuthukisiwe bokukhipha i-offloading njenge-RDMA phezu kwe-Converged Ethernet (RoCE), i-NVMe-oF, kanye ne-ASAP² yokushintsha okusheshayo kwehadiwe, i-MCX623436AN-CDAB inikeza i-ROI engenakuqhathaniswa ngokukhulula imijikelezo ye-CPU nokukhulisa ukusebenza kahle kwesistimu iyonke. Kungakhathaliseki ukuthi kunika amandla amaqoqo okuqeqesha e-AI, i-virtualization enkulu, noma ingqalasizinda ye-5G telco, le adaptha imelela indinganiso yegolide ekuthembekeni nasekusebenzeni kwenethiwekhi okusheshayo.
Incazelo Yomkhiqizo
Phakamisa Ukwakheka Kwesikhungo Sakho Sedatha: I-NVIDIA MCX623436AN-CDAB ConnectX-6 Dx ingaphezu nje kwe-100GbE NIC; iyimpahla ewusizo yengqalasizinda eqhutshwa yi-AI kanye nezindawo zamafu ezisezingeni eliphezulu. Yakhiwe nge-interface ye-QSFP56 enamachweba amabili, le adaptha inikeza i-bandwidth eqinile ye-200Gb/s, eyenzelwe ngqo ukuqeda izithiyo ze-I/O kuma-node eseva ye-PCIe 4.0 x16. Ngokushintshela kule platform ye-ConnectX-6 Dx, opharetha bangaqinisekisa ukuthi inethiwekhi yabo ihambisana nesivinini esikhulu sesitoreji se-NVMe sanamuhla kanye namaqoqo okuqeqesha e-AI.
Yakhelwe Ukusebenza Kwensimu Yesizukulwane Esilandelayo: Isebenzisa i-OCP Spec 3.0 Small Form Factor (SFF), leli khadi lenzelwe i-ecosystem yeseva yebhokisi elimhlophe yesimanje. Ngokungafani namakhadi e-PCIe ajwayelekile, umklamo we-OCP 3.0 wenza ngcono ukuphathwa kokushisa kanye nokuhamba komoya ngaphakathi kwama-rack aminyene. I-bracket ehlanganisiwe ye-Thumbscrew (Pull Tab) iyimininingwane ebalulekile yamaqembu obunjiniyela ase-US, evumela ukushintshana okusheshayo, okungenamathuluzi futhi inciphise isikhathi esimaphakathi sokulungisa (MTTR) ngesikhathi samafasitela okulungisa abalulekile.
Buyisela Amandla Akho Ekhompyutha (ROI Focus): Inani langempela le-ConnectX-6 Dx lisenjinini yayo yokukhipha "ehlakaniphile". Ngokusheshisa imisebenzi yehadiwe efana ne-RDMA (RoCE v2), i-NVMe-over-Fabrics (NVMe-oF), kanye nokushintsha kwe-ASAP², i-MCX623436AN-CDAB ibuyisa ama-CPU abalulekile abengachithwa ngaphandle kwenethiwekhi. Ngemithwalo yemisebenzi ye-AI kanye nokufunda komshini, lokhu kuhunyushwa ngqo ekusebenzeni kahle kokuqeqeshwa okuphezulu kanye ne-TCO ephansi, njengoba izinsiza zakho zokubala eziyinhloko zihlala zinikezelwe kuma-algorithms, hhayi ukunyakaza kwedatha.
