Data center kev sib txuasdaim ntawv thov tau dhau los ua ib feem tseem ceeb thiab loj hlob sai ntawm lub network sau. Kev loj hlob loj ntawm cov ntaub ntawv txhawb nqa kev tsim kho ntawm cov ntaub ntawv chaw ua si, tshwj xeeb tshaj yog kev tsim kho ntawm cov ntaub ntawv loj loj. Tam sim no, ob peb lub tsev hauv ib lub tsev kawm ntawv yuav tsum tau txuas nrog txaus bandwidth. Yuav tsum muaj bandwidth ntau npaum li cas los tswj kev khiav ntawm cov ntaub ntawv ntawm cov chaw zov me nyuam hauv ib lub tsev kawm ntawv? Txhua lub chaw khaws ntaub ntawv tuaj yeem hloov mus txog 200 Tbps ntawm lub peev xwm mus rau lwm lub chaw cov ntaub ntawv niaj hnub no, tab sis yuav tsum muaj ntau bandwidth yav tom ntej.
Dab tsi ua rau qhov kev thov loj rau bandwidth ntawm cov tsev kawm ntawv qib siab?
Ua ntej, kev loj hlob ntawm kev lag luam sab hnub tuaj-sab hnub poob (HT6000 WDM Optical Transmission Platform) tau txais kev txhawb nqa los ntawm cov khoom siv-rau-cov khoom sib txuas lus. Qhov thib ob txoj kev yuav tsum tau ua nrog rau kev saws me nyuam ntawm flatter network architectures, xws li cov spinal lobe network los yog CLOS network. Lub hom phiaj yog kom muaj cov qauv sib txuas loj hauv tsev kawm ntawv, uas yuav tsum muaj kev sib txuas ntau ntawm cov khoom siv.
Kev lig kev cai, cov chaw zov me nyuam yog tsim los ntawm peb-tier topology uas muaj cov tub ntxhais keyboards, sib sau ua ke keyboards thiab nkag mus. Txawm hais tias paub tab thiab siv dav, cov qauv peb-tier architecture tsis muaj peev xwm ua tau raws li kev ua haujlwm ntau ntxiv thiab ncua sijhawm ntawm ib puag ncig. Hauv kev teb, niaj hnub no cov ntaub ntawv loj heev tau tsiv mus rau ridgeback architecture. Nyob rau hauv lub lobed architecture, lub network muab faib ua ob theem. Lub ridge theem yog siv los sib sau cov pob ntawv thiab xa lawv mus rau lawv qhov chaw kawg, thiab cov nplooj ntawv theem yog siv los txuas rau lub party sab thiab load-balanced sib txuas.
Qhov zoo tshaj plaws, txhua nplooj ntawv hloov cov kiv cua tawm mus rau txhua qhov hloov pauv kom ua kom muaj kev sib txuas ntawm cov servers, yog li lub network xav tau qhov kev hloov pauv ntawm cov lej lej siab. Nyob rau hauv ntau qhov chaw, cov kev hloov loj loj tau txuas nrog cov kev hloov pauv siab dua, feem ntau hu ua lub tiaj ua si lossis polymer-ion ridge keyboards, txhawm rau txuas txhua lub tsev hauv lub tiaj ua si ua ke. Vim hais tias ntawm no flatter network architecture thiab siv high-precision keyboards, peb cia siab tias yuav pom cov tes hauj lwm ua loj, ntau modular, thiab ntau scalable.
