Molweni nonke. Njengoko sithembisile, sintywilisela abafundi beHabr kwiinkcukacha zokuveliswa kwezixhobo ze-hardware zaseRashiya kwiinkqubo zokugcina i-Aerodisk Vostok kwiiprosesa ze-Elbrus. Kweli nqaku siza kuchaza inyathelo ngenyathelo ukuveliswa kweqonga le-Yakhont-UVM E124, elibambe ngokufanelekileyo iidiski eziyi-5 kwiiyunithi ezi-124, inokusebenza kwiqondo lobushushu le-+30 degrees Celsius, kwaye kwangaxeshanye ayisebenzi nje kuphela, kodwa isebenza. kakuhle.
Siphinde siququzelele i-webinar ngomhla we-05.06.2020/XNUMX/XNUMX, apho siza kuthetha ngokuthe kratya malunga ne-technical nuances yemveliso yenkqubo yokugcina iVostok kwaye siphendule nayiphi na imibuzo. Ungabhalisela i-webinar usebenzisa ikhonkco:
Ngoko, masihambe!
Ngaphambi kokungena kwinkqubo eququzelelwayo ngoku, imvelaphi encinci yembali kwiminyaka emibini edlulileyo. Ngexesha lokuphuhliswa kwamaqonga achazwe kweli nqaku kwaqala, iimeko zokuvelisa kwazo zazikho, ukubeka ngobumnene, akukho. Kukho izizathu zale nto, ziyaziwa kuwo wonke umntu: ukuveliswa kobuninzi (okungukuthi ukuveliswa, kungekhona ukuphinda u-gluing of stickers) amaqonga omncedisi eRashiya ayengekho njengeklasi. Kwakukho iifektri ezahlukeneyo ezazinokuvelisa amacandelo ngamanye, kodwa ngendlela elinganiselwe kakhulu kwaye ngokufuthi ngokusekelwe kubugcisa obudala. Ke ngoko, kuye kwafuneka siqale "ukusuka ekuqaleni" kwaye kwangaxeshanye siphakamise imveliso yezisombululo zeseva eRashiya ukuya kwinqanaba elitsha elisemgangathweni.
Ngoko ke, inkqubo yayo nayiphi na imveliso iqala ngemfuno, eguqulwa ibe yimfuno ngokubanzi. Iimfuno ezinjalo ziqale zenziwe ngabaphuhlisi be-NORSI-TRANS eNizhny Novgorod. Iimfuno, ngokuqinisekileyo, azithathwanga emoyeni omncinci, kodwa kwiimfuno zabathengi. Lo ayingomsebenzi wobugcisa, njengoko kunokubonakala ngempazamo. Kwinqanaba leemfuno eziqhelekileyo, akunakwenzeka ukwenza inkcazo epheleleyo yobugcisa, kuba kukho iimeko ezininzi ezingaziwayo zokuvelisa.
Ukuphuhliswa kwemodeli ekujoliswe kuyo: ukusuka kwingcamango ukuya ekuphunyezweni
Emva kokuba iimfuno eziqhelekileyo zenziwe, ukhetho lwesiseko sezinto luqala. Ukususela kulwazi lwembali kulandela ukuba isiseko se-elementi asikho, oko kukuthi, kufuneka senziwe.
Ukwenza oku, isampuli yokulinga idityaniswe kwizinto ezikhoyo kwimarike evulekileyo, enokuthi ifane noko kujoliswe kuyo. Emva koko, iimvavanyo ezisemgangathweni zale sampuli ziyenziwa ukugqiba ukusebenza kwayo. Ukuba yonke into ilungile, ke isinyathelo esilandelayo kukuphuhlisa imodeli ekujoliswe kuyo (2D kunye ne-3D).
Emva koko ukukhangela kuqala kumashishini aseRashiya alungele ukuqala ukuveliswa kwalo mqhubi wenqwelomoya.
Ngethuba lenkqubo yokuyila, ukuguqulwa okufunekayo kwinto nganye yemveliso yenziwa. Ngokomzekelo, ngelixa usebenza kunye neprototype, i-classic 12G SAS izandisi kunye nenani elikhulu leengcingo zisetyenzisiwe (ezinkulu kakhulu, zinikwe inani leediski). Ayibizi, ayilunganga kweli qonga lithile, kwaye ngaphandle koko, abandisi botshaba bangaphandle. Kodwa esi sisisombululo sexeshana ukwenzela ukuvavanya isampuli ngokubanzi kwaye uqhubele phambili kwinqanaba elilandelayo. Nangona kunjalo, ayifanelekanga ukusebenzisa izandisi ze-SAS kwinguqulelo yokugqibela kwiqonga elithile leseva.
Asifuni izandisi zotshaba, siya kuzenzela inqwelomoya yethu nge-blackjack kunye ne-sh...
Ukuthathela ingqalelo izicwangciso zexesha elizayo zomthamo wemveliso (amawakawaka eeseva), kwagqitywa ekubeni kuphuhliswe le mveliso (kwaye, ewe, kwezilandelayo) eyethu inqwelo moya ye-SAS, esebenza ngakumbi kunokwandisa ngokunxulumene nesi sisombululo. . Uyilo kunye neprogram ye-backplane iqhutyelwa liqela elifanayo labaphuhlisi, kwaye ukuveliswa kweebhodi kuqhutyelwa kwisityalo seMicrolit kwingingqi yaseMoscow (sithembisa inqaku elahlukileyo malunga nesi sityalo kunye nendlela iibhodi ze-motherboards ze-Elbrus processors. ishicilelwe apho).
Ngendlela, nantsi iprototype yayo yokuqala, ngoku ibonakala ihluke ngokupheleleyo.
Kwaye apha bayayicwangcisa
Inyaniso enomdla: xa uphuhliso lwe-backplane lwaqala, kwaye abaqulunqi baphendukela kumphuhlisi we-SAS3 chip kuyilo lwebhodi yereferensi, kwavela ukuba akukho nkampani enye eYurophu eyazi indlela yokuphuhlisa i-backplanes yabo. Ngaphambili, kwakukho i-joint venture ye-Fujitsu-Siemens, kodwa emva kokuba i-Siemens Nixdorf Informations systeme AG ishiye i-joint venture kunye nokuvalwa ngokupheleleyo kwesebe lekhompyutha kwi-Siemens, ubuchule kule ndawo eYurophu kwalahleka.
Ngoko ke, umphuhlisi we-chip ekuqaleni akazange athabathe ngokukhawuleza uphuhliso lwe-NORSI-TRANS, nto leyo ebangele ukulibaziseka kuphuhliso loyilo lokugqibela. Enyanisweni, kamva, xa ubunzulu beenjongo kunye nobuchule benkampani ye-NORSI-TRANS babonakala, kwaye i-backplane yaphuhliswa kwaye yashicilelwa, isimo sakhe sengqondo satshintsha saba ngcono.
Indlela yokupholisa iidiski ze-124 kunye nomncedisi kwiiyunithi ezi-5, kwaye uhlale uphila?
Kwakukho imfuno eyahlukileyo kunye nokutya kunye nokupholisa. Inyani kukuba, ngokusekwe kwiimfuno, iqonga le-E124 kufuneka lisebenze kwiqondo lokushisa lama-30 degrees Celsius, kwaye apho, ngomzuzu, i-124 iidiski zoomatshini ezifudunyezwa kakuhle kwiiyunithi ezi-5 kwaye, ngaphezu koko, i-motherboard eneprosesa (okt. oku akusiyo i-JBOD yobudenge, kodwa umlawuli wenkqubo yokugcina epheleleyo enediski).
Ukupholisa (ngaphandle kwabalandeli abancinci ngaphakathi), ekugqibeleni sagqiba ekubeni sisebenzise abalandeli abathathu abakhulu ngasemva kwetyala, nganye ishushu-swappable. Ukusebenza okuqhelekileyo kwenkqubo, ezimbini zanele (iqondo lokushisa alitshintshi konke konke), ngoko unokucwangcisa ngokukhuselekileyo umsebenzi wokutshintsha abalandeli kwaye ungacingi ngeqondo lokushisa. Ukuba ucima abalandeli ababini (umzekelo, ngokomthetho woburhelem, ngelixa elinye litshintshwa, elesibini laphuka), ngoko ngefeni enye inkqubo inokusebenza ngokuqhelekileyo, kodwa izinga lokushisa liya kwanda nge-10-20%. ipesenti, eyamkelekileyo ngaphandle kokuba enye enye ngaphezulu ifakwe ifeni kungekudala.
Abalandeli (njengayo yonke enye into) nabo bavele baba babodwa. Isizathu sokungafani yayiyindleko enye. Kwiimeko ezithile, kunokwenzeka ukuba abalandeli, endaweni yokufunxa umoya, ukuvuthela yonke into ngaphakathi, bangaqala ukuyifaka, kwaye emva koko "goodbye", oko kukuthi, iqonga liya kukhawuleza ligqithise. Ke ngoko, ukuze kuthintelwe ingxaki enjalo, kwenziwa utshintsho kuyilo lwabalandeli kwaye songeza eyethu "ukwazi" - ivalve yokujonga. Le valve yokutshekisha izolile ivumela umoya ukuba ufunxe eqongeni, kodwa kwangaxeshanye ivalela amathuba okufunxa umoya nangayiphi na imeko.
Kwinqanaba lokuvavanya inkqubo yokupholisa, kukho ukungaphumeleli okuninzi, izinto ezahlukeneyo zenkqubo zigqithise kwaye zatshiswa, kodwa ekugqibeleni, abaphuhlisi beqonga bakwazile ukufezekisa ukupholisa okungcono kunabo bakhuphisana nabo abadumileyo kwihlabathi.
"Ukutya akunakwaphulwa."
Kwakuyibali elifanayo kunye nezixhobo zombane, okt. zenziwa ngokukodwa kweli qonga kwaye isizathu si-banal. Iyunithi nganye yimali eninzi, yingakho iqonga elinjalo elixineneyo laphuhliswa kwaye, ukuba andiphazamanga (ndichanekileyo kumazwana ukuba ndiphosakele), le yirekhodi yehlabathi ngoku, kuba Akukho ziseva okanye ii-JBOD ezinenani elikhulu leediski kwiiyunithi ezi-5 okwangoku.
Ngaloo ndlela, ukuze unikeze amandla eqongeni kwaye kwangaxeshanye uququzelele ithuba lokutshintsha unikezelo lwamandla ngendlela eqhelekileyo, amandla ewonke eeyunithi ezisebenzayo kufuneka abe ngama-kilowatts ama-4 (ngokuqinisekileyo, akukho zisombululo ezinjalo kwisixhobo sombane). imakethi), ngoko ke zenziwa ukuba ziodole ngokuqaliswa komgca wemveliso wemveliso yobuninzi ( Makhe ndikukhumbuze ukuba kukho izicwangciso zamawakawaka abancedisi abanjalo).
Njengoko omnye wabaqulunqi abaphambili beqonga wathi, "Imisinga apha ifana nomatshini wokuwelda - oku ayonwabisi kakhulu :-)"
Ngethuba loyilo, kwakunokwenzeka ukuba kusebenze ukunikezelwa kwamandla kungekhona kuphela kwi-220V, kodwa nakwi-48V, i.e. kwi-architecture ye-OPC, ngoku ibaluleke kakhulu kubaqhubi be-telecom kunye namaziko amakhulu edatha.
Ngenxa yoko, isisombululo esinombane siphinda ingqiqo yesisombululo ngokupholisa iqonga liyakwazi ukusebenza ngokukhululekileyo ngezinto ezimbini zombane, okwenza kube lula ukwenza umsebenzi wokutshintsha njengesiqhelo. Ukuba kwimeko yengozi kukho iyunithi enye yokubonelela umbane eshiywe ngaphandle kwezintathu, iya kukwazi ukukhupha umsebenzi weqonga kumthwalo ophakamileyo, kodwa, ngokuqinisekileyo, akunakwenzeka ukushiya iqonga kule fomu. ixesha elide.
Isinyithi kunye neplastiki: akusiyo yonke into elula, iyavela.
Kukho ama-nuances amaninzi kwinkqubo yophuhliso lweqonga. Imeko efanayo yenzeke kungekuphela nje ngamacandelo e-elektroniki (i-riers, i-backplanes, ii-motherboards, njl.), kodwa kunye nentsimbi eqhelekileyo kunye neplastiki: umzekelo, kunye necala, iileyili, kunye neenqwelo zedisk.
Kuya kubonakala ngathi akufuneki kubekho iingxaki ngomzimba kunye nezinye izinto ezincinci ezikrelekrele zeqonga. Kodwa ekusebenzeni yonke into yahlukile. Xa abaphuhlisi beqonga baqala ukusondela kwiifektri ezahlukeneyo zaseRussia ezinemfuno zemveliso, kwavela ukuba uninzi lwabo lwalusebenza kusetyenziswa iindlela ezingaqhelekanga, ezithe ekugqibeleni zachaphazela umgangatho kunye nobuninzi beemveliso.
Iziphumo zokuqala zokuveliswa kwamatyala zaba bubungqina boku. Ijometri engalunganga, i-welds rough, imingxuma engachanekanga kunye neendleko ezifanayo zenza ukuba imveliso ingafanelanga ukusetyenziswa.
Uninzi lweefektri ezinokuthi zenze iimeko zeseva zisebenze ngoko (makhe ndikukhumbuze ukuba ngokuthi "ngoko" sithetha iminyaka emi-2 eyadlulayo) "indlela yakudala," oko kukuthi, bavelise iqela lamaxwebhu oyilwayo, ngokuhambelana nawo. opharetha ngesandla uhlengahlengiso ukusebenza koomatshini, kwakhona ngokufuthi endaweni rivets ukuwelda ngentsimbi kwasetyenziswa. Ngenxa yoko, iqondo eliphantsi lokuzisebenzela, umba wobuntu kunye nokulawulwa ngokugqithisileyo kwemveliso kube neziqhamo. Kwavela ixesha elide, libi kwaye libiza.
Kufuneka sihlawule imbeko kwiifektri: uninzi lwazo ziphucule kakhulu imveliso yazo ukusukela ngelo xesha. Siye saphucula umgangatho wokuwelda, i-riveting eyingcweti, kwaye ngokufuthi saqalisa ukusebenzisa oomatshini bokulawula amanani ekhompyuter (CNC). Ngoku, endaweni yetoni yamaxwebhu, idatha yemveliso ilayishwa ngokuthe ngqo ukusuka kwimodeli ye-3D kunye ne-2D kwi-CNC.
I-CNC inciphisa ukungenelela komsebenzisi womatshini kwinkqubo yokuvelisa imveliso ibe yincinci, ngoko ke into yomntu ayisayi kuphazamisa ubomi. Inkxalabo ephambili yomsebenzisi ikakhulu kumalungiselelo kunye nokusebenza kokugqibela: ukufakwa kunye nokususwa kwemveliso, ukuseta izixhobo, njl.
Xa iinxalenye ezintsha zivela, imveliso ayisayi kumiswa ukuyivelisa, kwanele ukwenza utshintsho kwi-software ye-CNC. Ngokufanelekileyo, ixesha lokuvelisa iinxalenye zeeprojekthi ezintsha kwimizi-mveliso liye lancitshiswa ukusuka kwiinyanga ukuya kwiiveki, zindaba ezimnandi ke ezo. Kwaye, ngokuqinisekileyo, ukuchaneka kuye kwanda kakhulu.
Iibhodi zomama kunye neprosesa: akukho ngxaki
Iiprosesa kunye neebhodi zebhodi ziza njengeseti evela kumzi-mveliso. Le mveliso sele isekwe kakuhle, ngoko ke i-NORSI iqhuba ulawulo lwegalelo elisemgangathweni kunye nolawulo lwemveliso kwinqanaba lamaqonga agqityiweyo.
Iseti nganye yebhodi yomama kunye neprosesa ivavanywa ngesoftware efunyenwe kwi-MCST.
Kwimeko yeengxaki ezithile (siyabonga uThixo, bambalwa kakhulu kubo kunye nebhodi le-motherboard kunye neprosesa), kukho ikhonkco elisebenza kakuhle leemodyuli ezibuyisela kumenzi kunye nokutshintsha.
INdibano kunye nolawulo lokugqibela
Ukuze i-balalaika yethu iqale ukudlala, okuseleyo kukuhlanganisana kwaye kuyivavanye. Ngoku imveliso isendleleni, inkqubo ihlanganiswe ngendlela eqhelekileyo eMoscow.
Inkqubo nganye iza ne-boot SSDs (ye-OS) kunye ne-spindles epheleleyo (yedatha yexesha elizayo).
Emva koku, uvavanyo lwegalelo luqala zombini iqonga ngokwalo kunye neediski ezifakwe kuyo. Ukwenza oku, zonke iidiski kwinkqubo zilayishwa ngovavanyo oluzenzekelayo ubuncinane iyure.
Ukufunda nokubhala ngokuzenzekelayo kwenziwa kwidiski nganye, ukurekhoda isantya sokufunda, isantya sokubhala kunye nobushushu bediski nganye. Kwimo yesiqhelo, iqondo lobushushu eliphakathi kufuneka libe malunga ne-30-35 degrees Celsius. Kwiindawo eziphakamileyo, idiski nganye nganye "inokuthi iqhube" ukuya kuma-degrees angama-40. Ukuba iqondo lobushushu liba phezulu okanye isantya sehla ngaphantsi kwemigangatho yokufunda-bhala, idiski ijika ibe bomvu kwaye iyasilela ukwaliwa. Amacandelo aphumelele iimvavanyo apakishwa ukuze asetyenziswe ngakumbi.
isiphelo
Kukho intsomi exhaswa ngenkuthalo ngamanani ahlukeneyo athi "eRashiya abayazi indlela yokwenza nantoni na ngaphandle kweoli yokumpompa." Ngelishwa, le ntsomi idla kwiintloko zabantu abahlonitshwayo nabakrelekrele.
Kutshanje ibali elimangalisayo lenzekile kumlingane wam. Wayeqhuba ukusuka kwesinye semiboniso yenkqubo yokugcina iVostok kwaye le nkqubo yokugcina ilele kwi-trunk yemoto yakhe (kungekhona i-E124, ngokuqinisekileyo, ilula). Endleleni, wabamba omnye wabameli bomthengi (umntu obaluleke kakhulu, usebenza kwindawo ephezulu kwenye yee-arhente zaseburhulumenteni), kwaye emotweni bathetha malunga nale ncoko ilandelayo:
Umlingane wam: "Sisanda kubonisa inkqubo yokugcina kwi-Elbrus, iziphumo zazilungile, wonke umntu wayevuya, ngendlela, le nkqubo yokugcina iya kuba luncedo kwishishini lakho"
UmThengi: "Ndiyazi ukuba uneenkqubo zokugcina, kodwa luhlobo luni lwe-Elbrus othetha ngayo?"
Umlingane wam: "Ewe ... umprosesa waseRashiya u-Elbrus, basanda kukhulula i-8, ngokumalunga nokusebenza kweenkqubo zokugcina, thina, ngokufanelekileyo, senze umgca omtsha weenkqubo zokugcina kuyo, ezibizwa ngokuba yiVostok"
UmThengi: βI-Elbrus yintaba! Kwaye ungathethi iintsomi malunga neprosesa yaseRussia kuluntu oluthobekileyo, konke oku kwenziwa ukuze kufunyanwe uhlahlo lwabiwo-mali, enyanisweni akukho nto kwaye akukho nto iza kwenzeka. β
Umlingane wam: "Ngemimiselo yokuba? Ngaba kulungile ukuba le nkqubo yogcino isesiqwini sam? Masime ngoku, ndiza kukubonisa!"
UmThengi: "Kulungile ukubandezeleka ngobuvuvu, masiqhubele phambili, akukho "zinkqubo zokugcina zaseRashiya" - oku akunakwenzeka"
Ngelo xesha, umntu obalulekileyo akazange afune ukuva nantoni na ngo-Elbrus. Kakade ke, kamva, xa ecacisa ulwazi, wavuma ukuba wayengalunganga, kodwa kunjalo, de kube sekupheleni, wayengakholelwa ekunyaniseni kolu lwazi.
Enyanisweni, emva kokuwa kwe-USSR, ilizwe lethu layeka ngokwenene ekuphuhliseni imveliso ye-microelectronics. Into ethile yathunyelwa ngaphandle kwaye yabiwa ukuze kuxhamle iinkampani zamazwe ngamazwe, into eyayibiwe yinkampani yabucala yasekhaya, into ethile, ngokuqinisekileyo, yatyalwa imali, kodwa ngokukodwa ukuze kuzuze amaqumrhu afanayo angaphandle. Umthi wagawulwa, kodwa ingcambu yahlala.
Emva kweminyaka ephantse ibe yi-30 yeenkohliso malunga nesihloko esithi "iNtshona iya kusinceda," kuye kwacaca ukuba phantse wonke umntu sinokuzinceda kuphela, ngoko ke kufuneka sibuyisele imveliso yethu kuphela kwintsimi ye-microelectronics, kodwa kuwo onke amashishini. .
Okwangoku, kumxholo wendyikityha yehlabathi kwimeko apho amatyathanga emveliso yezizwe ngezizwe eyekile, sele kucaca ukuba ukubuyiselwa kwemveliso yasekhaya ayiselulo uphuhliso lohlahlo lwabiwo-mali, kodwa yimeko yokusinda kweRussia njengoko. ilizwe elizimeleyo.
Ke ngoko, siya kuqhubeka sijonga kwaye sisebenzise izixhobo zaseRussia ebomini kwaye sikuxelele malunga nokuba zenziwa ntoni iinkampani zethu, zeziphi iingxaki abajongene nazo kunye nemizamo ye-titanic abayenzayo ukuzisombulula.
Kunzima kakhulu ukuthetha ngayo yonke imiba yemveliso kwinqaku elinye, ke njengebhonasi siya kuququzelela ingxoxo ye-intanethi kwifomathi yewebhu yesi sihloko. Kule webinar, siza kuthetha ngokubanzi kunye nemibala ecacileyo malunga nemiba yobugcisa bokuveliswa kweeplatifomu ze-Yakhont kwiinkqubo zokugcina zeVostok kwaye ziya kuphendula zonke, nokuba zikhohlisi kakhulu, imibuzo kwi-intanethi.
I-interlocutor yethu iya kuba ngummeli womphuhlisi weqonga, inkampani ye-NORSI-TRANS. I-webinar iya kwenzeka nge-05.06.2020/XNUMX/XNUMX abo banqwenela ukuthatha inxaxheba banokubhalisa ngekhonkco: .
Ndiyanibulela nonke, njengesiqhelo, sijonge phambili kwizimvo ezakhayo.
