Lapho eminyakeni emithathu edlule sakwenza amamemori khadi okusetshenziswa ezimbonini, kumazwana bekukhona izifiso zokungakhulumi ngama-drones namakhamera - bathi, lokhu akuyona indawo ejwayelekile yokufakwa kwezicelo zamakhadi anjalo. KULUNGILE, sizitshele futhi sakubhala phansi ohlelweni lokuqukethwe - senza ukushicilelwa ngendaba evela embonini. Kodwa, njengoba kwenzeka, ngemuva kokugeleza kokushicilelwa ngemikhiqizo emisha ye-Kingston, le nto yahlala ohlwini olungemuva isikhathi eside, kwaze kwaba yilapho, ku-Habré, lapho sihlangana khona. . Usebenzise lawa mamemori khadi kusukela ngo-2016, futhi usebenzisa amakhulu awo. Ngendlela, ebhulohweni layo lomsakazo we-40-gigabit ngaphesheya kweYenisei, elaletha ukuxhumana okungenawaya, amamemori khadi afakiwe .
Isihloko secala ukuxhumana kwe-broadband kumagagasi angamamilimitha
Ekuqaleni kuka-2016, okungukuthi, lapho kanye amakhadi ememori ebanga lezimboni ze-Kingston avela ekubuyekezweni kwethu, ukweqa okuphakeme kwejubane lezixhumanisi zomsakazo ezingenazintambo kwakulungiswa emakethe yezokuxhumana. Isizukulwane sesibili seziteshi zomsakazo ezihamba ngesivinini esingu-1 Gbit/s, esikhonya ngo-2010-2015, bekufanele sidlulisele induku kuzixhumanisi zomsakazo zesizukulwane sesithathu ezikwazi ukusebenza ku-10 Gigabit Ethernet standard kanye nokudlulisa idatha ngesivinini esiyi-10. Gbit/s.

Ngendlela, ukuze wenze isiteshi somsakazo esinezici zokudlulisa ezifana nekhebula le-optical, okungenani izinto ezimbalwa zazidingeka emhlabeni wonke: ukwakhiwa kwesisekelo sesici esisha sokuxhumana okungenantambo 10 Gigabit Ethernet (10GE) kanye ukunikezwa kobubanzi befrikhwensi eyanele ngobubanzi lapho kungenzeka khona “ukulingana” 10 - ukusakaza kwedatha yegigabit. Lobu bubanzi bekuyisethi yamafrikhwensi 71-76/81-86 GHz, okwathi, ngesandla esilula somlawuli waseMelika iFCC, yabelwa e-USA ngo-2008. Ngokushesha lesi sibonelo salandelwa abalawuli cishe kuwo wonke amazwe omhlaba, okuhlanganisa i-Russia (ububanzi be-71-76/81-86 GHz buvunyelwe uMnyango Wezokuxhumana we-Russian Federation ukuze busetshenziswe mahhala kusukela ngo-2010).
Ngo-2016, ama-MMIC chips (amasekhethi ahlanganisiwe e-microwave monolithic) abedingwa abaklami, akwazi ukuhlinzeka ngokushintshwa kwesignali yomsakazo we-QAM 256 ngenani lokudluliswa kwedatha engu-10 Gbit/s, ekugcineni avele emakethe yomhlaba, futhi umjaho waqala ukubona ukuthi ubani ube ngowokuqala ukwethula amasampula okuhweba emishini yokudlulisa umsakazo wekilasi emakethe.. 10GE. Ngokumangalisayo, isampula yokuqala yokukhiqiza izixhumanisi zomsakazo ezinjalo zakhiwe eRussia enkampanini yobunjiniyela yaseSt. Petersburg i-DOK futhi iboniswe ku-Mobile World Congress (MWC 2017) e-Barcelona ngo-2017. Awu, kungani kungenjalo? - ngemva kwakho konke, u-Alexander Popov wasungula umsakazo eSt.
Namuhla, ngo-2019, imisakazo engenantambo ye-10GE isiphenduke indinganiso yemboni ye-de facto. Ngenxa yokuphuma kwayo okuphezulu, ulayini wokudlulisa umsakazo owodwa we-10 Gbit/s ngokuvamile usebenzela indawo yonke yokuhlala noma indawo enkulu yezimboni enezokuxhumana. Ama-opharetha amaselula ngokuzithandela asebenzisa izixhumanisi zomsakazo ze-10GE ukuze athole umgogodla phakathi kweziteshi eziyisisekelo ze-4G/LTE, ngoba baqinisekisa ukuvumelanisa kweziteshi eziyisisekelo newashi eliyinkomba lesikhungo sedatha sika-opharetha weselula, okubalulekile ekudluliseleni ithrafikhi ye-multimedia kuma-smartphone namathebulethi. Ngaphezu kocingo lwedijithali nokufinyelela ku-inthanethi, amakhulukhulu eziteshi ze-TV zedijithali zisakazwa ngesiteshi esingenantambo se-Gigabit Ethernet esingu-10, futhi kukhona ukusakazwa kwedatha evela kumakhamera e-CCTV.
“Konke lokhu kuyathakazelisa ngendlela yako,” kusho umfundi kaHabr, “kodwa ahlobene ngani namakhadi enkumbulo e-Kingston nakho?” Kodwa yilokhu esizodlulela kukho manje.
"Ibhokisi elimnyama" ngaphakathi kwemishini yokudlulisa umsakazo
Ikhadi lememori efakwe kumojula yokulawula yesiteshi somsakazo se-PPC-10G esakhiwe yi-DOK njengendawo yokugcina ifayela yamafayela okumisa nokungena kwesimo semishini. Yonke imingcele yokusebenza ebalulekile ibhalwa ekhadini ubusuku nemini: izinga lokudluliswa kwedatha esiteshini, izinga lesignali elitholiwe (i-RSL, Thola Izinga leSignali), izinga lokushisa esimweni, imingcele yokuphakelwa kwamandla nokunye okuningi. Ngokwemithetho yomkhiqizi, ikhadi kufanele ligcine idatha enjalo okungenani unyaka wokusebenza kwemishini, khona-ke idatha entsha ibhalwa phezu kwabadala. Ukuzijwayeza kubonise ukuthi ukuthobela lesi sidingo, umthamo wememori yekhadi ongu-8 GB wanele, ngakho i-DOK manje isebenzisa amakhadi anjalo. Isethi yeziteshi ezimbili ezidluliswayo zomsakazo idinga amamemori khadi amabili e-Industrial Temperature microSD UHS-I, ngoba ikhadi lifakwa kulowo nalowo.

Unjiniyela wenethiwekhi noma umlawuli we-telecom opharetha ngezikhathi ezithile ulanda amalogu kumemori khadi nge-FTP noma uwabuke kusixhumi esibonakalayo sewebhu. Ngale ndlela, izibalo zamandla eziteshi kanye nokuzinza kwezingxenye zangaphakathi zeziteshi zomsakazo ziyahlolwa. Ulwazi oluvela kulogi lubaluleke kakhulu uma kwenzeka ukungasebenzi kwemishini noma ukushintshelwa kwayo esilinganisweni esincishisiwe sokudlulisa idatha.
Besebenzisa ulwazi olusuka kumalogi anikezwe ikhasimende, ochwepheshe bosekelo lwezobuchwepheshe be-DOC bangaxilonga inkinga futhi baphakamise indlela eshesha kakhulu yokuyixazulula. Isibonelo, ngokubona ukuthi izinga lesignali etholiwe (i-RSL) lishintshile kusukela enkathini ethile, singaphetha ngokuthi, cishe, ukukhombana kwezimpondo komunye nomunye "kunephutha". Lokhu ngezinye izikhathi kwenzeka ngemva kokuba imimoya enamandla yesiphepho noma iqhwa liwela othini lisuka ezakhiweni eziphezulu zombhoshongo wezokuxhumana.
Opharetha beTelecom, lapho bethenga imishini yokudlulisela umsakazo eyi-10-gigabit ebiza kakhulu, bathembele ekuthembekeni okuphezulu kwazo zonke izingxenye zayo ngokomgomo othi “uwubeke bese uwukhohlwa”. Imemori khadi ayihlukile lapha. Isici esibalulekile lapha ubunzima bokuthola imishini yomsebenzi wokulungisa. Ezimweni eziningi kakhulu, izixhumanisi zomsakazo ku-71-76/81-86 GHz zifakwa emibhoshongweni yezokuxhumana, ophahleni lwezakhiwo nezakhiwo. Kuyacaca ukuthi ukugibela umbhoshongo oneqhwa ebusika baseRussia ukuze ushintshe izingxenye akuwona umsebenzi olula futhi oyingozi. Nakuba imemori khadi ingeyona ingxenye ebalulekile eziteshini ze-PPC-10G, futhi uma ihluleka, umugqa wokudlulisela umsakazo uzoqhubeka nokusebenza, kodwa ikhono lokurekhoda imishini kanye nezingodo zesimo sesiteshi sokuxhumana zizolahleka. Ngakho-ke, ukusebenza okuthembekile kwamakhadi ibalulekile kokubili kumkhiqizi wezixhumanisi zomsakazo nakumakhasimende amelwe ama-opharetha e-telecom.

“Sekuyiminyaka engaphezu kwengu-10 siklama futhi sikhiqiza iziteshi zomsakazo eRussia, futhi ngalesi sikhathi sizame amamemori khadi abakhiqizi abahlukene. Amanye amakhadi asebenze unyaka, amanye iminyaka embalwa, kodwa-ke kwakudingeka siwafomethe sikude, futhi ngezinye izikhathi ngisho nalokhu akuzange kusize, okwakubangela izikhalazo kubathengi bemishini yethu. Lapho imodeli ye-2016-Gigabit PPC-10G yethulwa ekukhiqizeni ku-10, saphendukela kumphakeli wethu, i-Superwave (St. Petersburg), ukuze uthole iseluleko. Bancome ama-memory card aseKingston ezimbonini, bethi nakanjani ngeke zibe khona izinkinga ngawo. Kusukela lapho, alikho nelilodwa ikhadi le-Kingston elihlulekile, futhi sesivele silifakile cishe inkulungwane. Futhi lokhu naphezu kweqiniso lokuthi imishini yezokuxhumana isebenza unyaka wonke ngaphandle ngaphansi kwezimo ezinzima kakhulu,” kuphawula uDaniil Korneev, umqondisi wenkampani ye-DOK.
Ungayidlula kanjani imikhawulo yokushisa yamamemori khadi nezinye izinto
Uma ubheka ikhasi nge Amamemori khadi e-Industrial Temperature microSD UHS-I, ungabona imikhawulo yebanga lawo lokushisa eliqinisekisiwe lokusebenza nesitoreji: ukusuka ku -40°C kuya ku-+85°C. Kodwa yini okufanele uyenze uma iziteshi zomsakazo zisebenza e-Arctic yaseRussia, lapho ebusuku kungaba kalula -50 ° C noma ngisho nangaphansi? Noma, ngokuphambene, kwenye indawo e-Afrika?

Ezimweni zasebusika, iziteshi zomsakazo zomsakazo zifakwe i-heater ezenzakalelayo, eqinisekisa izinga lokushisa ngaphakathi kwezindlu ezingaphezu kuka-0 ° C ngisho naseqhwa elinamandla. Endabeni "yesiqalo esibandayo," ngokufanisa nokwethulwa kwemishini yezimoto e-Arctic, i-heater iqala kuqala. Ivimbela ukushintshwa kwezingxenye ze-elekthronikhi kuze kube yilapho izinga lokushisa ngaphakathi kwekesi lesiteshi likhuphuka lifike emkhawulweni owamukelekayo.
Manje siya emkhawulweni ophezulu webanga lokushisa. Uma kucatshangelwa ukuthi ngamunye wabakhiqizi, kuhlanganise nabaseRussia, balwela ukuthengisa izixhumanisi zabo zomsakazo emhlabeni wonke, imishini kufanele isebenze ngokujwayelekile ngisho nangaphansi kwemisebe yelanga eshisayo. Ngokuguqulwa kwe-tropical, uhlelo olwandisiwe lwama-radiator lufakwa eziteshini ze-DOK, lusabalalisa ukushisa kuwo wonke umzimba wemishini.

“Njengokuphawula kwamakhadi ememori e-Kingston, ngingathanda ukuqaphela ukuthi umkhawulo ophansi wokushisa wesitoreji ongu--40 ° C ekucacisweni kwawo unikezwa nge-margin enkulu. Sekwenzeke kaningi kumakhasimende ethu avela ezifundeni ezisenyakatho yeRussia ukuthi iziteshi zomsakazo zicishwe emazingeni okushisa aphansi, futhi asikaze sibhale ukwehluleka kwamamemori khadi lapho okokusebenza kuvulwa. Ngokuqondene nomkhawulo wokushisa ongaphezulu, izingodo zokushisa ngaphakathi kwekesi, esiphinde sizithole kumamemori khadi e-Kingston, azizange zibonise ukudlula izinga lika +80°C lezixhumanisi zomsakazo eMpumalanga Ephakathi. Ngakho-ke ukwesaba ukuthi ilanga lizoshisa iziteshi kanye nezingxenye zazo ngaphezu komkhawulo ovunyelwe wamakhasimende ethu e-Riyadh noma e-Ajman kuvele kungenasisekelo, "uDaniil Korneev uzwakalise umbono wakhe mayelana namamemori khadi.
Leli ikesi elithakazelisayo lamamemori khadi i-Kingston Industrial Temperature microSD UHS-I esinikeze yona . Sithemba ukuthi sizoqhubeka nokushicilela izifundo zezindaba ezivela embonini nesayensi emikhiqizweni ehlukahlukene ye-Kingston maduze.
Bhalisela ibhulogi ye-Kingston Technology futhi uhlale ubukele.
Ukuze uthole ukwaziswa okwengeziwe mayelana nemikhiqizo bheka kuwebhusayithi yenkampani.
