IEEE P802.3ba, muyezo wotumizira deta pa 100 Gigabit Ethernet (100GbE), idapangidwa pakati pa 2007 ndi 2010 [3], koma idafalikira mu 2018 [5]. Chifukwa chiyani mu 2018 osati kale? Ndipo n'chifukwa chiyani nthawi yomweyo mu khamu? Pali zifukwa zosachepera zisanu zopangira izi...
IEEE P802.3ba idapangidwa makamaka kuti ikwaniritse zosowa za malo opangira ma data ndi zosowa za malo osinthira magalimoto pa intaneti (pakati pa ogwiritsa ntchito odziyimira pawokha); komanso kuwonetsetsa kuti ntchito zapaintaneti zogwiritsa ntchito zinthu zambiri sizimasokoneza, monga ma portal okhala ndi makanema ambiri (mwachitsanzo, YouTube); ndi makompyuta ochita bwino kwambiri. [3] Ogwiritsa ntchito intaneti wamba akuthandiziranso kusintha kwa bandwidth: Anthu ambiri ali ndi makamera a digito, ndipo anthu amafuna kutulutsa zomwe amajambula pa intaneti. Kuti. Kuchuluka kwa zinthu zomwe zikuyenda pa intaneti zikuchulukirachulukira pakapita nthawi. Onse pamlingo waukadaulo komanso ogula. Muzochitika zonsezi, posamutsa deta kuchokera ku dera lina kupita ku lina, kuchuluka kwa ma node ofunikira pa intaneti kwadutsa kale mphamvu zamadoko a 10GbE. [1] Ichi ndi chifukwa cha kutuluka kwa muyezo watsopano: 100GbE.
Malo akuluakulu a deta ndi opereka chithandizo chamtambo akugwiritsa ntchito kale 100GbE, ndipo akukonzekera kupita ku 200GbE ndi 400GbE m'zaka zingapo. Panthawi imodzimodziyo, akuyang'ana kale pa liwiro loposa terabit. [6] Ngakhale pali ena ogulitsa akuluakulu omwe akusamukira ku 100GbE chaka chatha chokha (mwachitsanzo, Microsoft Azure). Malo opangira deta omwe amagwiritsira ntchito makompyuta apamwamba kwambiri a ntchito zachuma, nsanja za boma, mafuta ndi gasi nsanja ndi zothandizira zayambanso kusamukira ku 100GbE. [5]
M'malo opangira mabizinesi, kufunikira kwa bandwidth ndikotsika pang'ono: posachedwapa pomwe 10GbE yakhala yofunika m'malo mwapamwamba pano. Komabe, momwe kuchuluka kwa magalimoto kumachulukirachulukira, ndizokayikitsa kuti 10GbE idzakhala m'malo opangira mabizinesi kwazaka zosachepera 10 kapena 5. M'malo mwake, tiwona kusuntha mwachangu kupita ku 25GbE komanso kusuntha mwachangu kupita ku 100GbE. [6] Chifukwa, monga momwe akatswiri a Intel amanenera, kuchuluka kwa magalimoto mkati mwa data center kumawonjezeka pachaka ndi 25%. [5]
Ofufuza ochokera ku Dell ndi Hewlett Packard akunena [4] kuti 2018 ndi chaka cha 100GbE cha malo opangira deta. Kubwerera mu Ogasiti 2018, kutumizidwa kwa zida za 100GbE kunali kokulirapo kawiri kuposa kutumizidwa kwa chaka chonse cha 2017. Ndipo mayendedwe otumizira akupitilizabe kuthamanga pomwe malo opangira ma data akuyamba kuchoka pa 40GbE m'magulu. Zikuyembekezeka kuti pofika chaka cha 2022, madoko 19,4 miliyoni a 100GbE azitumizidwa chaka chilichonse (mu 2017, poyerekeza, chiwerengerochi chinali 4,6 miliyoni). [4] Ponena za ndalama, mu 2017 $ 100 biliyoni adagwiritsidwa ntchito pa madoko a 7GbE, ndipo mu 2020, malinga ndi maulosi, pafupifupi $ 20 biliyoni idzagwiritsidwa ntchito (onani mkuyu 1). [1]
Chithunzi 1. Ziwerengero ndi zoneneratu za kufunikira kwa zida zapaintaneti
Chifukwa chiyani tsopano? 100GbE siukadaulo watsopano, ndiye chifukwa chiyani pali hype yochuluka mozungulira pano?
1) Chifukwa ukadaulo uwu wakhwima ndipo watsika mtengo. Munali mu 2018 pamene tidawoloka mzere pogwiritsa ntchito nsanja zokhala ndi ma doko a 100-Gigabit mu data center zinakhala zotsika mtengo kusiyana ndi "stacking" angapo 10-Gigabit nsanja. Chitsanzo: Ciena 5170 (onani Chithunzi 2) ndi nsanja yophatikizika yomwe imapereka mphamvu zonse za 800GbE (4x100GbE, 40x10GbE). Ngati madoko angapo a 10-Gigabit akufunika kuti apereke zofunikira, ndiye kuti mtengo wa hardware yowonjezera, malo owonjezera, kugwiritsira ntchito mphamvu zambiri, kukonzanso kosalekeza, zina zowonjezera zowonjezera ndi machitidwe oziziritsa owonjezera amawonjezera ndalama zowoneka bwino. [1] Mwachitsanzo, akatswiri a Hewlett Packard, pofufuza ubwino wochoka ku 10GbE kupita ku 100GbE, adafika paziwerengero zotsatirazi: ntchito zapamwamba (56%), ndalama zotsika mtengo (27%), kuchepa kwa mphamvu (31%), kulumikiza chingwe chosavuta (ndi 38%). [5]

2) Juniper ndi Cisco potsiriza adapanga ma ASIC awo akusintha kwa 100GbE. [5] Umenewu ndi umboni womveka bwino wakuti teknoloji ya 100GbE ndiyokhwimadi. Chowonadi ndi chakuti ndizotsika mtengo kupanga tchipisi ta ASIC pokhapokha, choyamba, malingaliro omwe akhazikitsidwa pa iwo safuna kusintha kwamtsogolo, ndipo kachiwiri, pamene tchipisi tambiri tofanana tapangidwa. Juniper ndi Cisco sakanatulutsa ma ASIC awa popanda kukhala ndi chidaliro pakukula kwa 100GbE.
3) Chifukwa Broadcom, Cavium, ndi Mellanox Technologie ayamba kutulutsa mapurosesa ndi chithandizo cha 100GbE, ndipo mapurosesawa amagwiritsidwa ntchito kale posintha kuchokera kwa opanga monga Dell, Hewlett Packard, Huawei Technologies, Lenovo Group, etc. [5]
4) Chifukwa ma seva omwe amakhala muzitsulo za seva amakhala ndi zida zaposachedwa kwambiri za Intel network (onani Chithunzi 3), okhala ndi madoko awiri a 25-Gigabit, ndipo nthawi zina amasinthira ma adapter a network okhala ndi ma doko awiri a 40-Gigabit (XXV710 ndi XL710). {Chithunzi 3. Ma Intel NIC aposachedwa: XXV710 ndi XL710}
5) Chifukwa zida za 100GbE zimagwirizana kumbuyo, zomwe zimathandizira kutumiza: mutha kugwiritsanso ntchito zingwe zoyendetsedwa kale (ingolumikizani transceiver yatsopano kwa iwo).
Kuonjezera apo, kupezeka kwa 100GbE kumatikonzekeretsa matekinoloje atsopano monga "NVMe over Fabrics" (mwachitsanzo, Samsung Evo Pro 256 GB NVMe PCIe SSD; onani Chithunzi 4) [8, 10], "Storage Area Network" (SAN) ) / "Kusungirako Kusungirako Mapulogalamu" (onani Chithunzi 5) [7], RDMA [11], yomwe popanda 100GbE sinathe kuzindikira mphamvu zawo zonse.

Potsirizira pake, monga chitsanzo chachilendo cha zofunikira zogwiritsira ntchito 100GbE ndi matekinoloje othamanga kwambiri, tikhoza kutchula mtambo wa sayansi wa yunivesite ya Cambridge (onani mkuyu 6), yomwe imamangidwa pamaziko a 100GbE (Spectrum). SN2700 Ethernet switches) - mwadongosolo, mwa zina, kuonetsetsa kuti ntchito yabwino ya NexentaEdge SDS yogawira disk yosungirako, yomwe imatha kudzaza mosavuta 10 / 40GbE network. [2] Mitambo yasayansi yogwira ntchito kwambiri yotereyi imayikidwa kuti ithetse mavuto osiyanasiyana ogwiritsidwa ntchito asayansi [9, 12]. Mwachitsanzo, asayansi azachipatala amagwiritsa ntchito mitambo yotereyi kuti adziwe zamtundu wa munthu, ndipo njira za 100GbE zimagwiritsidwa ntchito kusamutsa zidziwitso pakati pa magulu ofufuza a ku yunivesite.
