No nā makahiki ʻelima a ʻehiku i hala aku nei, ʻo ka wikiwiki maʻamau o ka pilina ma waena o kahi lau Top of Rack (ToR) e hoʻololi i ka subtending kamepiula a me nā kikowaena mālama mālama ʻo 10Gbps.Nui nā kikowaena data hyperscale a ʻoi aku ka nui o nā kikowaena data ʻoihana e neʻe nei i kēia mau loulou i 25Gbps.Hiki ke kūkulu ʻia kēia mau pilina me ka 25Gbps Direct Attached Copper cables (DACs), Active Optical Cables (AOCs), a i ʻole me kahi pālua o SFP28 25Gbps optical transceivers a me kahi duplex fiber optic jumper cable kūpono.
No ka hōʻike ʻana i kēia noi me nā huahana o ka honua maoli, ua koho ʻia kahi hoʻololi ToR mai Cisco's Nexus 3000 series a me kahi server i kau ʻia mai Supermicro.ʻO nā ʻāpana ʻē aʻe wale nō i koi ʻia ʻo Fiberconcepts SFP-25G-SR-s multimode transceivers a me OM4 multimode patch cables.
KA LAAU TOR: CiscoNexus 34180YC
ʻO ke kahua ʻo Nexus 3400 kahi ʻāpana o ka hanauna hou loa o ka Nexus®3000 Series Switches.Kuhi ʻia ka moʻo 3000 no nā noi ToR.ʻO nā lālā a pau he mau huahana hoʻonohonoho paʻa (1RU).Ma waena o kēia ʻohana huahana, hāʻawi ʻia nā kumukūʻai āpau o ka optical ethernet, mai 1G a 400G.
ʻO ka Nexus 34180YC kahi hoʻololi kūpono e hōʻike i ka hoʻohana ʻia o ka brand INTCERA, Cisco compatible SFP-25G-SR-S transceiver.Hāʻawi kēia hoʻololi i ka maʻalahi i nā awa wikiwiki, e uhi ana i nā helu 1G, 10G, 25G, 40G a me 100G.Hiki ke hoʻolālā ʻia ka 34180YC e ʻae i ka mea hoʻohana i nā mea kūʻai aku e hoʻololi i ka ʻano hoʻouna i ka packet i nā pono o kā lākou noi.No ka laʻana, hiki ke hoʻonui ʻia nā noi kālepa kālā wikiwiki no ka latency haʻahaʻa loa.Hoʻokomo ʻia kēia hoʻololi me nā awa 48 SFP + / SFP28 (1G / 10G / 25G) a me 6 QSFP + / QSFP28 (40G / 100G).Kākoʻo ka hoʻololi i ka laina laina piha Layer 2/3 e hoʻololi i kēia mau awa a pau, ka huina o 3.6 Terabits/sec a me 1.4 Gigapackets/sec.
Hiki ke hoʻolako ʻia ka 34180YC me kahi ākea ākea o nā ʻano transceiver interface ma waena o nā kumukūʻai i ʻōlelo ʻia ma luna.Aia nā papa ma lalo nei nā ʻano transceiver kūpono no nā ʻano ʻelua o nā awa i ka hoʻololi.
