100GbE: khoom kim heev lossis qhov tseem ceeb?

IEEE P802.3ba, tus qauv rau kev xa cov ntaub ntawv ntau dua 100 Gigabit Ethernet (100GbE), tau tsim los ntawm 2007 thiab 2010 [3], tab sis tsuas yog tau nthuav dav hauv 2018 [5]. Vim li cas xyoo 2018 thiab tsis ua ntej? Thiab yog vim li cas tam sim ntawd nyob rau hauv droves? Muaj tsawg kawg yog tsib lub laj thawj rau qhov no ...

IEEE P802.3ba yog tsim los ua kom tau raws li cov kev xav tau ntawm cov chaw zov me nyuam cov ntaub ntawv thiab cov kev xav tau ntawm kev sib pauv tsheb hauv Internet (nruab nrab ntawm cov neeg ua haujlwm ywj pheej); ntxiv rau kom ntseeg tau tias kev ua haujlwm tsis cuam tshuam ntawm cov kev pabcuam hauv lub vev xaib, xws li portals nrog ntau cov ntsiab lus video (piv txwv li, YouTube); thiab rau kev ua haujlwm siab. [3] Cov neeg siv Is Taws Nem zoo ib yam kuj tau pab txhawb kev hloov pauv kev xav tau: Ntau tus neeg muaj lub koob yees duab digital, thiab tib neeg xav tshaj tawm cov ntsiab lus uas lawv ntes hauv Is Taws Nem. Qhov ntawd. Qhov ntim ntawm cov ntsiab lus nthuav dav hauv Is Taws Nem tau dhau los ua qhov loj thiab loj dua lub sijhawm. Ob leeg ntawm cov kws tshaj lij thiab cov neeg siv khoom. Nyob rau hauv tag nrho cov no, thaum hloov cov ntaub ntawv los ntawm ib tug sau mus rau lwm tus, tag nrho cov hla dhau ntawm cov tseem ceeb network nodes tau ntev tshaj lub peev xwm ntawm 10GbE ports. [1] Qhov no yog vim li cas rau qhov tshwm sim ntawm tus qauv tshiab: 100GbE.

Cov chaw loj cov ntaub ntawv thiab cov chaw muab kev pabcuam huab tau nquag siv 100GbE, thiab npaj yuav maj mam txav mus rau 200GbE thiab 400GbE hauv ob peb xyoos. Nyob rau tib lub sij hawm, lawv twb saib ntawm speeds tshaj terabit. [6] Txawm hais tias muaj qee tus neeg xa khoom loj uas tau tsiv mus rau 100GbE tsuas yog xyoo tas los (piv txwv li Microsoft Azure). Cov chaw khaws ntaub ntawv khiav lag luam kev ua haujlwm siab rau kev pabcuam nyiaj txiag, tsoomfwv platforms, roj thiab roj platforms thiab cov khoom siv hluav taws xob kuj tau pib txav mus rau 100GbE. [5]

Hauv cov chaw lag luam cov ntaub ntawv, qhov kev thov rau bandwidth yog qis dua: tsuas yog tsis ntev los no muaj 10GbE dhau los ua qhov tsim nyog es tsis yog khoom kim heev ntawm no. Txawm li cas los xij, raws li tus nqi ntawm kev siv tsheb loj zuj zus tuaj, nws tsis ntseeg tias 10GbE yuav nyob hauv cov chaw lag luam cov ntaub ntawv tsawg kawg 10 lossis 5 xyoo. Hloov chaw, peb yuav pom qhov nrawm nrawm mus rau 25GbE thiab nrawm dua mus rau 100GbE. [6] Vim hais tias, raws li Intel cov kws tshuaj ntsuam xyuas, qhov kev siv ntawm cov tsheb khiav hauv cov ntaub ntawv chaw nce txhua xyoo los ntawm 25%. [5]

Cov kws tshuaj ntsuam xyuas los ntawm Dell thiab Hewlett Packard xeev [4] tias 2018 yog xyoo 100GbE rau cov chaw khaws ntaub ntawv. Rov qab rau lub Yim Hli 2018, kev xa khoom ntawm 100GbE cov cuab yeej siv tau ob zaug siab dua cov khoom xa tuaj rau tag nrho 2017 xyoo. Thiab cov pace ntawm kev xa khoom mus txuas ntxiv kom nrawm thaum cov ntaub ntawv chaw pib txav deb ntawm 40GbE hauv kev tsav tsheb. Nws cia siab tias los ntawm 2022, 19,4 lab 100GbE cov chaw nres nkoj yuav raug xa tawm txhua xyoo (hauv 2017, rau kev sib piv, daim duab no yog 4,6 lab). [4] Raws li cov nqi, hauv 2017 $ 100 billion tau siv rau ntawm 7GbE cov chaw nres nkoj, thiab hauv 2020, raws li kev kwv yees, kwv yees li $ 20 billion yuav siv (saib daim duab 1). [1]

Vim li cas tam sim no? 100GbE tsis yog ib lub tshuab tshiab, yog li vim li cas thiaj li muaj ntau yam hype nyob ib ncig ntawm nws tam sim no?

1) Vim tias cov cuab yeej no tau loj hlob thiab ua pheej yig dua. Nws yog nyob rau hauv 2018 uas peb hla txoj kab thaum siv platforms nrog 100-Gigabit ports nyob rau hauv cov ntaub ntawv chaw los ua tus nqi-zoo tshaj li "stacking" ob peb 10-Gigabit platforms. Piv txwv li: Ciena 5170 (saib daim duab 2) yog lub platform compact uas muab kev sib sau ua ke ntawm 800GbE (4x100GbE, 40x10GbE). Yog tias ntau qhov chaw nres nkoj 10-Gigabit yuav tsum tau muab qhov tsim nyog dhau los, ces tus nqi ntawm cov khoom siv ntxiv, qhov chaw ntxiv, kev siv hluav taws xob ntau dhau, kev saib xyuas tsis tu ncua, cov khoom seem ntxiv thiab cov tshuab cua txias ntxiv kom zoo nkauj zoo nkauj. [1] Piv txwv li, Hewlett Packard cov kws tshaj lij, tshuaj xyuas cov txiaj ntsig muaj peev xwm ntawm kev txav ntawm 10GbE mus rau 100GbE, tuaj rau cov duab hauv qab no: kev ua tau zoo dua (56%), txo nqi tag nrho (27%), qis zog siv (31%), simplification cable txuas (los ntawm 38%). [5]

2) Juniper thiab Cisco thaum kawg tau tsim lawv tus kheej ASICs rau 100GbE keyboards. [5] Uas yog eloquent kev lees paub ntawm qhov tseeb tias 100GbE thev naus laus zis yog qhov paub tab tiag tiag. Qhov tseeb yog tias nws yog tus nqi tsim nyog los tsim ASIC chips tsuas yog thaum, thawj zaug, cov logic siv rau lawv tsis tas yuav muaj kev hloov pauv hauv lub neej yav tom ntej, thiab qhov thib ob, thaum muaj ntau cov chips zoo tib yam tsim. Juniper thiab Cisco yuav tsis tsim cov ASICs yam tsis muaj kev ntseeg siab hauv kev loj hlob ntawm 100GbE.

3) Vim tias Broadcom, Cavium, thiab Mellanox Technologie tau pib churning tawm processors nrog 100GbE kev txhawb nqa, thiab cov txheej txheem no twb tau siv los ntawm cov chaw tsim khoom xws li Dell, Hewlett Packard, Huawei Technologies, Lenovo Group, thiab lwm yam. [5]

4) Vim tias cov servers nyob hauv server racks tau nce ntxiv nrog qhov tseeb Intel network adapters (saib daim duab 3), nrog ob lub 25-Gigabit ports, thiab qee zaum txawm converged network adapters nrog ob 40-Gigabit ports (XXV710 thiab XL710). {Daim duab 3. Tseeb Intel NICs: XXV710 thiab XL710}

5) Vim hais tias 100GbE cov cuab yeej rov qab tau sib xws, uas yooj yim rau kev xa tawm: koj tuaj yeem rov siv tau cov cables uas twb muaj lawm (tsuas yog txuas lub transceiver tshiab rau lawv).

Ntxiv rau, qhov muaj 100GbE npaj peb rau cov thev naus laus zis tshiab xws li "NVMe dhau Fabrics" (piv txwv li, Samsung Evo Pro 256 GB NVMe PCIe SSD; saib daim duab 4) [8, 10], "Storage Area Network" (SAN ) / “Software Defined Storage” (saib daim duab 5) [7], RDMA [11], uas tsis muaj 100GbE tsis tuaj yeem paub lawv lub peev xwm tag nrho.

Thaum kawg, raws li ib qho piv txwv txawv ntawm qhov kev xav tau ntawm kev siv 100GbE thiab lwm yam kev siv thev naus laus zis, peb tuaj yeem hais txog huab cua ntawm University of Cambridge (saib daim duab 6), uas yog tsim los ntawm 100GbE (Spectrum). SN2700 Ethernet keyboards) - nyob rau hauv kev txiav txim, ntawm lwm yam, xyuas kom meej cov hauj lwm zoo ntawm NexentaEdge SDS faib disk cia, uas yuav yooj yim overload ib 10/40GbE network. [2] Cov huab cua kev tshawb fawb zoo li no tau siv los daws ntau yam teeb meem kev tshawb fawb [9, 12]. Piv txwv li, cov kws tshawb fawb kho mob siv cov huab cua no los txiav txim siab txog tib neeg genome, thiab 100GbE cov channel yog siv los hloov cov ntaub ntawv ntawm cov pab pawg tshawb fawb hauv tsev kawm.
