Izintengo zokushintshwa kwezikhungo zedatha zehle ngo-2018. Abahlaziyi balindele ukuthi lo mkhuba uqhubeke ngo-2019. Ngezansi kokusikwa sizothola ukuthi siyini isizathu.

Amathrendi
Ngokombiko wenhlangano yocwaningo i-IDC, imakethe yomhlaba wonke yokushintsha kwesikhungo sedatha - engxenyeni yesine ye-2018, ukuthengiswa kokushintshwa kwe-Ethernet kukhuphuke ngo-12,7% futhi kwafinyelela ku-$ 7,82 billion. Izindleko zehle kakhulu ku-2018GbE: ekupheleni kwe-100 yona I-$ 532 ngechweba ngalinye, futhi ekupheleni kwe-2018 - kakade i-$ 288 ngechweba ngalinye. Intengo iphinde yehla ku-40GbE - isuka ku-$478 yaya ku-$400 ngechweba ngalinye.
Idatha ye-IDC iqinisekiswa umbiko weCrehan Research. Ngokusho kwabo , phakathi kuka-2014β2018 izindleko zokushintshwa kwe-ethernet zehle ngesilinganiso esingu-5%. Ukwehliswa kwentengo kanye nochwepheshe be-Gartner: embikweni wangonyaka odlule bacebise izikhungo zedatha ukuthi zishintshe zisuka ku-10GbE kanye ne-40GbE zobuchwepheshe ziye ku-100 GbE ngenxa yezindleko eziphansi zemishini. Ochwepheshe bakhuluma ngezizathu eziningana.
Ukuncintisana okuphezulu
Abakhiqizi bokushintsha baphoqeleka ukuthi behlise amanani entengo yemishini yabo ngenxa yokuncintisana okuvela -izinqumo. Ngokukhulayo, izinkampani nezikhungo zedatha zikhetha kakhulu amaswishi βangenabhrendiβ ngenxa yamandla amakhulu okwenza ngendlela oyifisayo amadivaysi anjalo - asebenza nenani elikhulu lamasistimu ahlukene okusebenza futhi -izinqumo.
Futhi, amasistimu e-whitebox ngokuvamile ashibhile kunokushintsha kokuphathelene. Isibonelo kungaba icala lenye yezinkampani zokudlala - amadivaysi e-whitebox izinhlangano zishibhe ngokuphindwe kangamashumi amabili kunohlelo olufanayo oluvela ezinkundleni zokuxhumana ze-IT.
Namuhla, ngisho nezinkampani ezinkulu ze-IT zikhiqiza amadivaysi e-whitebox. Ukushintsha kwakho ngoMashi I-Facebook - Inezimbobo ze-100GbE kanye ne-400GbE. Ukucaciswa kwayo kuzodluliselwa kuphrojekthi futhi uyivule ngokuphelele.

Ukusabalala kwe-Virtualization
Ngu I-Statista, ngo-2021, u-94% wemisebenzi yesikhungo sedatha izobe isisetshenziswa ngendlela ebonakalayo. Ngesikhathi esifanayo, ukwethulwa kwamadivayisi wenethiwekhi ebonakalayo kungenye yezintathu opharetha besikhungo sedatha eYurophu naseNyakatho Melika. Lo mkhuba uholela ekwehleni kwesidingo sokushintshwa ngokomzimba kanye nokusabalala kwezixazululo ze-SDN.
Kulindeleke ukuthi eminyakeni emithathu ezayo umthamo wethrafikhi odlula ezinhlelweni zesikhungo sedatha ye-SDN uzoba : ukusuka ku-3,1 zettabytes ukuya ku-7,4 zettabytes. Abahlaziyi , okuzophinda kubangele ukwanda kwesidingo samarutha ebhokisi elimhlophe.
Ukuvuthwa kwezobuchwepheshe
Ukwehliswa kwezindleko kuphinde kuhlotshaniswe nokuthuthukiswa okusebenzayo kwe-Ethernet kanye nokuvela kwamazinga amasha. Ngo-2018, abakhiqizi bedivaysi yenethiwekhi baqala ukushintshela ku-400GbE: imikhiqizo yokuhweba ye-400-gigabit Cisco, Juniper kanye no-Arista.
Ukuthuthukiswa kwezinga elisha kuholela ekwehleni kwamanani ezizukulwaneni ezedlule ze-Ethernet. Ukwehla okuphawulekayo kwezindleko zamadivayisi we-100GbE ngonyaka odlule kube. Kuvele ukuthi bekungalindelekile nakubahlaziyi - ngokusho kuka abamele iqembu locwaningo lwe-Dell'Oro, ochwepheshe babikezela ukuncishiswa kwentengo kuze kube sezingeni lokuphela kwe-2018 kuphela ngekota yokugcina ka-2019.
Ochwepheshe baphinde bahlobanise izindleko eziwayo ze-100GbE nokuthuthukiswa kobuchwepheshe. Abakhiqizi bebelokhu bekhiqiza amadivayisi ayi-100-gigabit kusukela cishe ngo-2011 - ngalesi sikhathi, ukukhiqizwa kuye kwaba ngcono, futhi izindleko zokudala izinguquko zehlile.

Kwenzekani kwezinye izimakethe zemishini yesikhungo sedatha
Amaseva, ngokungafani namaswishi, abiza kakhulu. Ukwenyuka kuhlotshaniswa nezindleko ezikhulayo zamaphrosesa: ngo-2018, imakethe ibhekane nokushoda kwama-chips avela ku-Intel ngenxa yokwanda okubukhali kwesidingo sama-CPU avela ezikhungweni zedatha. Esimweni sokushoda kwama-processor, amanani abo ayatholakala kwabanye abathengisi isikhathi esisodwa nengxenye.
Ukushoda kwama-chip kulindeleke ukuthi kuqhubeke kuze kube okungenani ikota yesithathu ka-2019. Ngesikhathi esifanayo, isidingo siyaqhubeka sikhula: izikhungo eziningi zedatha zishintsha amamodeli ama-chip amadala ngamasha avikelwe ekubeni sengozini ye-Specter ne-Meltdown. Kungenzeka ukuthi izintengo zamaphrosesa namaseva kulesi simo zizoqhubeka nokukhuphuka.
Uma sibheka imboni yokugcinwa kwedatha, kukhona ukwehla kwezindleko zamadrayivu aqinile-state (SSDs). Ngokusho kukaGartner, intengo ye-SSD kusuka ku-2018 kuya ku-2021 2,5 izikhathi. Uma lokhu kwenzeka, ochwepheshe bathi amadrayivu e-solid-state azoqala ukukhipha ama-hard drive kusuka ezikhungweni zedatha. Ama-HDD athatha isikhala esiningi kakhulu futhi awathembekile kunama-SSD. Uma isimo esiqinile sishayela izinga lokuhluleka 0,5%, bese kuthi kuma-hard drive lesi sibalo singama-2-5%.
okutholakele
Ngokuvamile, singasho ukuthi ukuncipha kwezindleko kuhlotshaniswa nokuthuthukiswa okusheshayo kwemakethe yemishini yesikhungo sedatha. Ngokuzayo, izintengo zingase zehle kwezinye izingxenyekazi zekhompyutha zezikhungo zedatha.
Iya ngokuya idume izixazululo zebhokisi elimhlophe esigabeni seseva futhi. Uma lo mkhuba uqhubeka, izintengo zemishini yeseva zingase ziqale ukushintsha ziye phansi.
