Xa kwiminyaka emithathu edlulileyo senza iimemori khadi zokusetyenziswa kwimizi-mveliso, kwizimvo kukho iminqweno yokungathethi malunga needrones kunye neekhamera - bathi, oku akusiyo indawo eqhelekileyo yesicelo samakhadi ememori anjalo. Kulungile, sizixelele kwaye sabhala phantsi kwisicwangciso somxholo - yenza upapasho ngetyala elivela kumashishini. Kodwa, njengoko kwenzeka, emva kokuhamba kweempapasho malunga neemveliso ezintsha ze-Kingston, le nto yahlala kuluhlu lwangasemva ixesha elide, kwaze kwaba yilapho, eHabrΓ©, sadibana. . Ebesebenzisa la makhadi ukusukela ngo-2016, kwaye usebenzisa amakhulukhulu awo. Ngendlela, kwibhulorho yerediyo ye-40-gigabit ngaphesheya kweYenisei, eyazisa unxibelelwano olungenazingcingo, iimemori khadi zifakiwe .
Umba womxholo wetyala lunxibelelwano lwebroadband kumaza emilimitha
Ekuqaleni kuka-2016, oko kukuthi, kanye xa kwavela amakhadi ememori eKingston kwishishini lethu, ukutsiba okusemgangathweni kwisantya samakhonkco erediyo angenazingcingo kwakulungiswa kwimarike yonxibelelwano. Isizukulwana sesibini sezikhululo zomsakazo werediyo ngesantya se-1 Gbit / s, esilawulayo kwi-2010-2015, bekufanele ukuba sidlulisele i-baton kwi-radio ye-third links ezikwazi ukusebenza kumgangatho we-10 Gigabit Ethernet kunye nokudlulisa idatha ngesantya se-10. Gbit/s.

Ngendlela, ukuze wenze umjelo werediyo kunye neempawu zothumelo ezifana nentambo ye-optical, ubuncinane izinto ezimbalwa ezifunekayo kwinqanaba lehlabathi: ukudalwa kwesiseko esitsha sonxibelelwano olungenazintambo 10 Gigabit Ethernet (10GE) kunye ukunikezelwa koluhlu lwamaza okwaneleyo ngobubanzi apho kunokwenzeka ukuba "ulungele" i-10 - i-gigabit data stream. Olu luhlu lwaluyisethi ye-frequencies 71-76 / 81-86 GHz, leyo, ngesandla esilula somlawuli waseMelika iFCC, yabelwa e-USA kwi-2008. Kungekudala lo mzekelo walandelwa ngabalawuli phantse kuwo onke amazwe ehlabathi, kuquka iRashiya (uluhlu lwe-71-76 / 81-86 GHz luye lwavunyelwa nguMphathiswa wezoNxibelelwano lweRussian Federation ukuba lusetyenziswe simahla ukususela ngo-2010).
Ngo-2016, iitshiphusi zeMMIC (iisekethe ezidityanisiweyo ze-microwave monolithic) ezidingwa ngabayili, ezikwaziyo ukubonelela nge-QAM 256 yokumodareyitha kophawu lonomathotholo kwireyithi yokudluliselwa kwedatha ye-10 Gbit/s, ekugqibeleni yabonakala kwimarike yehlabathi, kwaye ugqatso lwaqala ukubona ukuba ngubani oza kuphinda abone ukuba ngubani oza kuphumelela. ube ngowokuqala ukusungula iisampulu zentengiso yezixhobo zerediyo zeklasi kwimarike 10GE. Okumangalisa kukuba, isampuli yokuqala yokuvelisa izixhumanisi zerediyo ezinjalo zenziwa eRashiya kwinkampani yobunjineli baseSt. Petersburg DOK kwaye iboniswe kwi-Mobile World Congress (MWC 2017) e-Barcelona kwi-2017. Kaloku, kutheni kungenjalo? - emva koko, u-Alexander Popov wasungula irediyo eSt.
Namhlanje, ngo-2019, iirediyo ze-10GE ezingenazingcingo ziye zaba ngumgangatho weshishini le-de facto. Ngombulelo kwimveliso yayo ephezulu, i-10 Gbit/s intambo yonomathotholo enye ihlala isebenzela indawo yokuhlala okanye indawo enkulu yemizi-mveliso enonxibelelwano. Abaqhubi beeselula ngokuzithandela basebenzisa i-10GE amakhonkco erediyo kwi-backbones phakathi kwezikhululo ezisisiseko ze-4G/LTE, kuba baqinisekisa ulungelelwaniso lwezikhululo ezisisiseko kunye newotshi yereferensi yeziko ledatha yabaqhubi beselula, okubalulekileyo ekudluliseleni i-multimedia traffic kwii-smartphones kunye neetafile. Ukongeza kwi-telephony yedijithali kunye nokufikelela kwi-Intanethi, amakhulu eziteshi zeTV zedijithali zisasazwa nge-10 Gigabit Ethernet ishaneli engenazintambo, kwaye kukho umlambo wedatha kwiikhamera zeCCTV.
βYonke le nto inomdla ngendlela yayo,β uya kuthi umfundi kaHabr, βkodwa iimemori khadi zaseKingston zinento yokwenza nayo?β Kodwa yile nto siza kuqhubekela kuyo ngoku.
"Ibhokisi elimnyama" ngaphakathi kwezixhobo zerediyo
Ikhadi lememori efakwe kwimodyuli yolawulo ye-PPC-10G yomsakazo werediyo owenziwe yi-DOK njengendawo yokugcina ifayile yeefayile zoqwalaselo kunye nokugawulwa kwemeko yezixhobo. Zonke iiparameters ezibalulekileyo zokusebenza zibhalwa kwikhadi malunga newashi: izinga lokudluliselwa kwedatha kwitshaneli, inqanaba lesignali elifunyenweyo (i-RSL, iNqanaba lokuFumana iSignali), ukushisa kwimeko, iiparitha zokunikezelwa kwamandla kunye nokunye okuninzi. Ngokutsho kwemithetho yomenzi, ikhadi kufuneka ligcine idatha enjalo ubuncinane ngonyaka wokusebenza kwezixhobo, ngoko idatha entsha ibhalwe ngaphezulu kwezidala. Ukuziqhelanisa kubonise ukuba ukuthobela le mfuneko, imemori yememori ye-8 GB yanele, ngoko i-DOK ngoku isebenzisa amakhadi anjalo. Iseti yezikhululo zonomathotholo ezibini zifuna iimemori khadi ezimbini ze-Industrial Temperature microSD UHS-I, kuba ikhadi lifakwe kuzo zonke.

Injineli yenethiwekhi okanye umlawuli womsebenzisi we-telecom ngamaxesha athile ukhuphela iilogi ukusuka kwimemori khadi nge-FTP okanye uzijonge kujongano lwewebhu. Ngale ndlela, iinkcukacha-manani malunga nomthamo wetshaneli kunye nokuzinza kwamacandelo angaphakathi kwizikhululo zerediyo zosasazo ziyahlolwa. Ulwazi oluvela kwizigodo lubaluleke kakhulu xa kukho ukungaphumeleli kwezixhobo okanye ukutshintshwa kwayo kwizinga elincitshisiweyo lokudlulisa idatha.
Ukusebenzisa ulwazi olusuka kwizigodo ezinikezelwe ngumthengi, iingcali zenkxaso yezobugcisa ze-DOC ziyakwazi ukuxilonga ingxaki kwaye zicebise eyona ndlela ikhawulezayo yokuyicombulula. Ngokomzekelo, xa sibona ukuba inqanaba lomqondiso ofunyenweyo (i-RSL) litshintshile ukusuka kumzuzu othile, sinokugqiba ukuba, mhlawumbi, ukukhomba i-eriyali komnye nomnye "kungalunganga". Ngamanye amaxesha oku kwenzeka emva kokuba imimoya yenkanyamba okanye umkhenkce uwela kwi-eriyali evela kwizakhiwo eziphezulu zenqaba yonxibelelwano.
Abaqhubi be-Telecom, xa kuthengwa izixhobo zerediyo ze-10-gigabit ezibiza kakhulu, bathembele ekuthembekeni okuphezulu kwazo zonke iinxalenye zayo ngokomgaqo othi "uyibeke kwaye uyilibale". Ikhadi lememori alikho ngaphandle apha. Into ebalulekileyo apha kubunzima bokufikelela kwisixhobo somsebenzi wokulungisa. Kwiimeko ezininzi kakhulu, iikhonkco zerediyo kuluhlu lwe-71-76 / 81-86 GHz zifakwe kwiinqaba zonxibelelwano, kuphahla lwezakhiwo kunye nezakhiwo. Kucacile ukuba ukunyuka kwinqaba enomkhenkce ebusika baseRashiya ukubuyisela amacandelo akuyona into elula kwaye iyingozi. Nangona imemori khadi ayiyona nto ibalulekileyo kwizikhululo ze-PPC-10G, kwaye ukuba ihluleka, umgca we-radio relay uya kuqhubeka nokusebenza, kodwa ukukwazi ukurekhoda izixhobo kunye neelogi zesimo sonxibelelwano ziya kulahleka. Ngoko ke, ukusebenza okuthembekileyo kwamakhadi ibalulekile kumvelisi wamakhonkco erediyo kunye nakubathengi abamelwe ngabaqhubi be-telecom.

βBesiyila kwaye sivelisa izitishi zikanomathotholo eRashiya iminyaka engaphezu kwe-10, kwaye ngeli xesha sizame iimemori khadi ezivela kubenzi abahlukeneyo. Amanye amakhadi asebenza unyaka, amanye iminyaka embalwa, kodwa ke kwafuneka siwafomethe ukude, yaye ngamanye amaxesha kwa oku akuzange kuncede nto, nto leyo eyayibangela izikhalazo kubathengi bezixhobo zethu. Xa imodeli ye-2016-Gigabit PPC-10G yasungulwa kwimveliso kwi-10, saphendukela kumthengisi wethu, i-Superwave (eSt. Petersburg), ukuze sifumane iingcebiso. Bacebise ngeememori khadi zaseKingston, besithi ngokuqinisekileyo akukho ngxaki kubo. Ukusukela ngoko, akukho nelinye ikhadi likaKingston elasilelayo, kwaye sele sifakile malunga newaka. Kwaye oku ngaphandle kwento yokuba izixhobo zonxibelelwano zisebenza unyaka wonke ngaphandle kwiimeko ezinzima kakhulu, utshilo uDaniil Korneev, umlawuli wenkampani yeDOK.
Uyigqitha njani imida yobushushu beememori khadi kunye nezinye izinto
Ukuba ujonga iphepha nge Ubushushu boShishino lwamakhadi ememori ye-microSD UHS-I, unokubona imida yokusebenza kwabo okuqinisekisiweyo kunye noluhlu lobushushu bokugcina: ukusuka -40 Β° C ukuya +85 Β° C. Kodwa yintoni enokuyenza ukuba izikhululo zomsakazo werediyo zisebenza kwi-Arctic yaseRashiya, apho ebusuku kunokuba lula -50 Β° C okanye nangaphantsi? Okanye, ngokuchaseneyo, kwenye indawo eAfrika?
