Amaxabiso okutshintsha kwamaziko edatha ehle ngo-2018. Abahlalutyi balindele ukuba imeko iqhubeke ngo-2019. Ngezantsi kokusikwa siza kufumanisa ukuba yintoni isizathu.

Ngokwengxelo yentlangano yophando ye-IDC, imarike yehlabathi jikelele yokutshintsha iziko ledatha - kwikota yesine ye-2018, ukuthengiswa kwee-switch switch ze-Ethernet kwanda ngo-12,7% kwaye kwafikelela kwi-7,82 2018 yeebhiliyoni zeedola.Naphezu kokunyuka kweemfuno, ixabiso lezixhobo liyehla kwi-100. Iindleko zehla kakhulu kwi-2017GbE: ekupheleni kwe-XNUMX yona I-$ 532 ngechweba ngalinye, kwaye ekupheleni kwe-2018 - sele sele i-$ 288 ngechweba ngalinye. Ixabiso libuye lehla kwi-40GbE - ukusuka kwi-$ 478 ukuya kwi-$ 400 ngechweba ngalinye.
Idatha ye-IDC iqinisekiswa yingxelo yoPhando lweCrehan. Ngokutsho kwabo , ngexesha le-2014-2018 iindleko zokutshintsha kwe-ethernet zawa ngomyinge we-5%. Ukwehliswa kwexabiso kunye neengcali zeGartner: kwingxelo yonyaka odlulileyo bacebise amaziko edatha ukuba atshintshe ukusuka kwi-10GbE kunye ne-40GbE teknoloji ukuya kwi-100 GbE ngenxa yeendleko zezixhobo eziphantsi. Iingcali zithetha ngezizathu ezininzi.
Ukhuphiswano oluphezulu
Abavelisi bokutshintsha banyanzelekile ukuba banciphise amaxabiso ezixhobo zabo ngenxa yokhuphiswano oluvela -izigqibo. Ngokwandayo, iinkampani kunye namaziko edatha anika ukhetho "olungenagama" lokutshintsha ngenxa yesakhono esikhulu sokwenza ngokwezifiso ezo zixhobo - zisebenza nenani elikhulu leenkqubo ezahlukeneyo zokusebenza kwaye -izigqibo.
Kwakhona, iinkqubo zebhokisi emhlophe zihlala zinexabiso eliphantsi kunokutshintsha kobunikazi. Umzekelo unokuba yimeko enye yeenkampani zokudlala - izixhobo ze-whitebox imibutho ngamashumi amabini aphindwe ngexabiso eliphantsi kunenkqubo efanayo evela kwizigebenga ze-IT.
Namhlanje, iinkampani ezinkulu ze-IT zivelisa izixhobo ze-whitebox. NgoMatshi, utshintsho lwakho I-Facebook - Ine-100GbE kunye ne-400GbE izibuko. Iinkcukacha zayo ziya kudluliselwa kwiprojekthi kwaye uyivule ngokupheleleyo.

Ukusasazeka kweVirtualization
Ngu I-Statista, ngo-2021, i-94% yomthwalo womsebenzi weziko ledatha iya kwenziwa ngokubonakalayo. Ngexesha elifanayo, ukuqaliswa kwezixhobo zenethiwekhi yenyani enye yezintathu kubasebenzisi beziko ledatha eYurophu naseMntla Melika. Lo mkhwa ukhokelela ekunciphiseni kwemfuno yokutshintsha komzimba kunye nokusasazeka kwezisombululo ze-SDN.
Kulindeleke ukuba kwiminyaka emithathu ezayo umthamo wezithuthi ezidlula kwiinkqubo zedatha ye-SDN ziya : ukusuka kwi-3,1 zettabytes ukuya kwi-7,4 zettabytes. Abahlalutyi , okuya kuphinda kubangele ukwanda kweemfuno ze-whitebox routers.
Ukuvuthwa kweTekhnoloji
Ukunciphisa iindleko kukwadibaniswa nophuhliso olusebenzayo lwe-Ethernet kunye nokuvela kwemigangatho emitsha. Kwi-2018, abavelisi bezixhobo zenethiwekhi baqala ukutshintshela kwi-400GbE: iimveliso ze-400-gigabit zorhwebo. UCisco, uJuniper kunye noArista.
Ukuphuhliswa komgangatho omtsha kukhokelela ekwehleni kwamaxabiso kwizizukulwana zangaphambili ze-Ethernet. Ukuncipha okuphawulekayo kweendleko ze-100GbE izixhobo kunyaka odlulileyo kuye kwaba. Kwavela ukuba bekungalindelekanga nakubahlalutyi - ngokutsho abameli beqela lophando lweDell'Oro, iingcali zaxela ukuncitshiswa kwexabiso ukuya kwinqanaba lokuphela kwe-2018 kuphela kwikota yokugqibela ye-2019.
Iingcali ziphinda zidibanise iindleko eziwa phantsi kwe-100GbE kunye nophuhliso lobuchwepheshe. Abavelisi baye bavelisa izixhobo ze-100-gigabit ukususela malunga ne-2011 - ngeli xesha, imveliso iphuculwe, kwaye iindleko zokudala utshintsho ziye zancipha.

Kwenzeka ntoni kwezinye iimarike zezixhobo zedatha
Iiseva, ngokungafaniyo nokutshintsha, zibiza kakhulu. Ukunyuka kuhambelana neendleko ezikhulayo zeprosesa: kwi-2018, imarike ijongene nokunqongophala kwee-chips ezivela kwi-Intel ngenxa yokunyuka okubukhali kweemfuno ze-CPU ezivela kumaziko edatha. Kwimeko yokunqongophala kweeprosesa, amaxabiso abo ayafumaneka kwabanye abathengisi ixesha elinye elinesiqingatha.
Ukunqongophala kwe-chip kulindeleke ukuba kuqhubeke kude kube yikota yesithathu ka-2019. Ngexesha elifanayo, imfuno iyaqhubeka ikhula: amaninzi amaziko edatha athatha indawo yemodeli ye-chip endala kunye nezitsha ezikhuselweyo kwi-Specter kunye ne-Meltdown vulnerabilities. Kusenokwenzeka ukuba amaxabiso abaqhubekekisi kunye neeseva kule meko aya kuqhubeka nokunyuka.
Ukuba sijonga imboni yogcino lwedatha, kukho ukuhla kweendleko ze-solid-state drives (SSDs). Ngokutsho kukaGartner, ixabiso le-SSD ukusuka kwi-2018 ukuya kwi-2021 2,5 amaxesha. Ukuba oku kuyenzeka, iingcali zithi i-slid-state drives iya kuqala ukususa ngokusebenzayo ii-hard drives kumaziko edatha. Ii-HDD zithatha indawo eninzi kakhulu kwaye azithembeki kangako kune-SSD. Ukuba imeko eqinileyo iqhuba izinga lokusilela I-0,5%, ngoko kwii-hard drives lo mfanekiso ngu-2-5%.
ezifunyanisiweyo
Ngokubanzi, sinokuthi ukuncitshiswa kweendleko kuhambelana nophuhliso olukhawulezayo lwemakethe yezixhobo zedatha. Kwixesha elizayo, amaxabiso angawa kwezinye ihardware kumaziko edatha.
Iya ithandwa kakhulu izisombululo zebhokisi emhlophe kwicandelo lomncedisi ngokunjalo. Ukuba le meko iyaqhubeka, ke amaxabiso ezixhobo zeseva anokuqala ukutshintshela ezantsi.
