Sawubona, bahlali abathandekayo baseKhabrovsk!
Ngingathanda ukuqhubeka nodaba lwami mayelana nokuhlanganisa “ikhompuyutha eyisupha yedolobha”. Futhi ngizochaza ukuthi kungani kubizwa kanjalo-isizathu silula. Mina ngokwami ngihlala esigodini. Futhi igama liwukunyakaziswa kancane kwalabo abamemeza ku-inthanethi "Akukho ukuphila ngale komgwaqo waseMoscow Ring!", "Idolobhana laseRussia seliphenduke isidakwa futhi liyafa!" Ngakho-ke, endaweni ethile lokhu kungase kube yiqiniso, kodwa ngizoba ngaphandle komthetho. Angiphuzi, angibhemi, ngenza izinto okungezona zonke “ama-cracker(ama) asemadolobheni” angakwazi ukuzikhokhela. Kodwa ake sibuyele ezimvini zethu, noma ngokunembe kakhudlwana, kusiphakeli, lokho ekupheleni kwengxenye yokuqala yesihloko kakade “esasibonisa izimpawu zokuphila.”
Ibhodi lalilele etafuleni, ngakhuphuka nge-BIOS, ngayimisa ngendlela engiyithandayo, ngachitha i-Ubuntu 16.04 Desktop ukuze kube lula futhi nganquma ukuxhuma ikhadi levidiyo "emshinini omkhulu". Kepha okuwukuphela kwento eyayikhona kwakuyi-GTS 250 ene-hefty non-original fan enamathiselwe. Engiyifake ku-PCI-E 16x slot eduze kwenkinobho yamandla.
"Ngiyithathe nephakethe le-Belomor (c)" ngakho ngicela ungangisoli ngekhwalithi yesithombe. Ngingathanda ukuphawula ngalokho okuthwetshulwe ngabo.
Okokuqala, kwavela ukuthi lapho efakwe ku-slot, ngisho nekhadi levidiyo elifushane libeka ibhodi ngokumelene nezikhala zememori, lapho kulokhu ayikwazi ukufakwa futhi ngisho nama-latches kufanele ehliswe. Okwesibili, umugqa wokukhweza wensimbi wekhadi levidiyo uvala inkinobho yamandla, ngakho-ke bekufanele ususwe. Kodwa-ke, inkinobho yamandla ngokwayo ikhanyiswa yi-LED enemibala emibili, ekhanyisa ngokuluhlaza uma yonke into isilungile bese icwayiza okusawolintshi uma kukhona izinkinga, isekethe emfishane kanye nokuvikelwa kokunikezwa kwamandla kukhubekile noma amandla +12VSB ukunikezwa kuphezulu kakhulu noma kuphansi kakhulu.
Eqinisweni, le bhodi yomama ayakhelwe ukuthi ifake amakhadi evidiyo “ngqo” ezindaweni zayo ze-PCI-E 16x; wonke axhunywe kuzikhuphukeli. Ukuze ufake ikhadi lokunweba ezindaweni eziseduze nenkinobho yamandla, kukhona izikhuphukeli zamakhona, esiphansi sokufaka amakhadi amafushane afika kubude berediyetha yokuqala yokucubungula, kanye nekhona eliphezulu elinesixhumi samandla esingeziwe esingu-+12V sokufaka i-radiator. ikhadi levidiyo “ngenhla” isipholile esisezingeni eliphansi esingu-1U. Ingafaka amakhadi amakhulu evidiyo afana ne-GTX 780, i-GTX 980, i-GTX 1080 noma amakhadi akhethekile e-GPGPU i-Nvidia Tesla K10-K20-K40 noma “amakhadi ekhompyutha” Intel Xeon Phi 5110p nokunye okunjalo.
Kodwa kusikhuphukeli se-GPGPU, ikhadi elifakwe ku-EdgeSlot lingaxhunywa ngokuqondile, kuphela ngokuphinda futhi lixhume amandla engeziwe ngesixhumi esifanayo nasokukhuphukeni kwekhona eliphezulu. Kulabo abanentshisekelo, ku-eBay lesi sikhuphukeli esiguquguqukayo sibizwa ngokuthi "Dell PowerEdge C8220X PCI-E GPGPU DJC89" futhi kubiza cishe ama-ruble ayizinkulungwane ezingu-2.5-3. Izikhuphukeli zasemakhoneni ezinogesi owengeziwe zingavamile kakhulu futhi kudingeke ngixoxisane ukuze ngizithole esitolo sezingxenye zesiphakeli esikhethekile nge-Whisper. Babiza izinkulungwane eziyisi-7 lilinye.
Ngizothi khona manjalo, “abafana abayingozi (tm)” bangakwazi nokuxhuma ipheya ye-GTX 980 ebhodini ngezikhuphukeli eziguquguqukayo zaseShayina 16x, njengoba kwenza umuntu oyedwa “Kuleyo Foramu Efanayo”; ngendlela, amaShayina enza kahle. imisebenzi yezandla emihle esebenza ku-PCI-E 16x 2.0 ngesitayela se-Thermaltek flexible ones risers, kodwa uma lokhu ngolunye usuku kubangela ukuthi ushise amasekhethi amandla ebhodini leseva, uzozibeka icala kuphela. Angizange ngibeke engozini imishini ebizayo futhi ngasebenzisa izikhuphukeli zangempela ezinamandla engeziwe kanye neyodwa yaseShayina eguquguqukayo, ngicabanga ukuthi ukuxhuma ikhadi elilodwa "ngokuqondile" ngeke kushise ibhodi.
Khona-ke izixhumi ebezilindelwe isikhathi eside zokuxhuma amandla engeziwe zafika futhi ngenza umsila wesikhuphukeli sami ku-EdgeSlot. Futhi isixhumi esifanayo, kodwa ngephinikhodi ehlukile, sisetshenziselwa ukunikeza amandla engeziwe ebhodini lomama. Lesi sixhumi siseduze kwalesi sixhumi esifanayo se-EdgeSlot, kukhona i-pinout ethakazelisayo lapho. Uma isikhuphukeli sinezintambo ezi-2 +12 no-2 ezivamile, ibhodi linezintambo ezi-3 +12 kanye no-1 ovamile.
Lokhu empeleni i-GTS 250 efanayo efakwe kusikhuphukeli se-GPGPU. Ngendlela, amandla engeziwe anikezwa izikhuphukeli kanye nebhodi lomama - kusukela kusixhumi samandla sesibili se-+12V se-CPU yokunikezwa kwamandla ami. Nganquma ukuthi kuyoba okulungile kakhulu ukwenza lokhu.
Inganekwane izitshela ngokushesha, kodwa kancane kancane amaphasela afika eRussia evela eChina nakwezinye izindawo emhlabeni jikelele. Ngakho-ke, kwakukhona izikhala ezinkulu ekuhlanganiseni "i-supercomputer". Kodwa ekugcineni iseva ye-Nvidia Tesla K20M ene-radiator engenzi lutho yafika kimi. Ngaphezu kwalokho, inguziro ngokuphelele, kusukela kusitoreji, ivalwe ebhokisini layo langempela, ephaketheni layo langempela, elinamaphepha ewaranti. Futhi ukuhlupheka kwaqala: kanjani ukupholisa?
Okokuqala, i-cooler yangokwezifiso "enama-turbine" amabili amancane yathengwa eNgilandi, nansi esithombeni, ene-diffuser eyenziwe ekhaya yamakhadibhodi.
Futhi kwavela ukuthi bangamaphutha ngokuphelele. Benza umsindo omkhulu, intaba ayizange ihambisane nakancane, bashaya kancane futhi banikeza ukudlidliza kangangokuthi ngesaba ukuthi izingxenye zizowa ebhodini leTesla! Kungani belahlwe kudoti ngokushesha nje?
Ngendlela, esithombeni esingaphansi kwe-Tesla ungabona ama-radiator e-LGA 2011 1U iseva yethusi efakwe kumaphrosesa ngomnenke ovela ku-Coolerserver othengwe kwa-Aliexpress. Ama-coolers ahloniphekile, nakuba enomsindo omncane. Zilingana ngokuphelele.
Kodwa empeleni, ngenkathi ngisalinde i-cooler entsha ye-Tesla, kulokhu ngi-ode umnenke omkhulu we-BFB1012EN ovela e-Australia nge-3D ephrintiwe ukukhweza, yafika ohlelweni lokugcina iseva. Ibhodi leseva linesixhumi esincane se-SAS lapho kukhishwa khona izixhumi ezi-4 SATA nezi-2 ngaphezulu ze-SATA. Yonke i-SATA standard 2.0 kodwa lokho kuyangifanela.
I-intel C602 RAID ehlanganiswe ku-chipset ayikubi futhi into esemqoka ukuthi yeqa umyalo we-TRIM wama-SSD, abalawuli abaningi be-RAID bangaphandle abangabizi abawenzi.
Ku-eBay ngithenge ikhebuli ye-mini-SAS eya ku-4 SATA engamamitha ubude, kwathi ku-Avito ngathenga inqola eshintshashintshayo ene-5,25″ bay engu-4 x 2,5″ SAS-SATA. Ngakho lapho ikhebula nebhasikidi zifika, ama-Seagates angu-4 afakwe kuwo, i-RAID5 yamadivayisi angu-4 yakhiwe ku-BIOS, ngaqala ukufaka iseva Ubuntu ... futhi ngagijimela eqinisweni lokuthi uhlelo lokuhlukanisa i-disk alungivumeli ukudala ukwahlukanisa kokushintshana ekugaseleni.
Ngixazulule inkinga mathupha - ngithenge i-adaptha ye-ASUS HYPER M.2 x 2 MINI ne-M.4 SSD Samsung 2 EVO 960 Gb kusuka ku-DNS futhi nganquma ukuthi idivayisi yesivinini esiphezulu kufanele yabelwe ukushintsha, njengoba isistimu izosebenza. ngomthwalo omkhulu wokubala, futhi inkumbulo isengaphansi kosayizi wedatha ngokusobala. Futhi inkumbulo engu-250 GB ibibiza kakhulu kunale SSD.
Le adaptha efanayo ene-SSD efakwe kusikhuphukeli sekhona eliphansi.
Ukulindela imibuzo - “Kungani ungenzi isistimu yonke ku-M.2 futhi ube nesivinini sokufinyelela esiphezulu sibe phezulu kunesokuhlasela kwe-SATA?” - Ngizophendula. Okokuqala, i-1 TB noma ngaphezulu ama-M2 SSD ayabiza kakhulu kimi. Okwesibili, ngisho nangemva kokubuyekeza i-BIOS enguqulweni yakamuva engu-2.8.1, iseva namanje ayikusekeli ukulayisha amadivayisi we-M.2 NVE. Ngenze isilingo lapho isistimu isethelwe/iqalisa ku-USB FLASH 64 Gb nakho konke okunye ku-M.2 SSD, kodwa angiyithandanga. Nakuba, ngokomthetho, inhlanganisela enjalo iyasebenza ngempela. Uma umthamo omkhulu we-M.2 NVEs ushibhile, ngingase ngibuyele kule nketho, kodwa okwamanje i-SATA RAID njengesistimu yokugcina ingifanela kahle.
Lapho nginquma nge-subsystem yediski futhi ngiqhamuka nenhlanganisela ye-2 x SSD Kingston 240 Gb RAID1 “/” + 4 x HDD Seagate 1 Tb RAID5 “/home” + M.2 SSD Samsung 960 EVO 250 Gb “swap” isikhathi sokuqhubeka nokuhlola kwami nge-GPU Bengivele ngine-Tesla kanye ne-cooler yase-Australia esanda kufika nomnenke "omubi" odla okuningi njenge-2.94A ku-12V, i-slot yesibili yayithathwe i-M.2 futhi okwesithathu ngaboleka i-GT 610 "ngokuhlola."
Lapha esithombeni wonke amadivaysi angu-3 axhunyiwe, futhi i-M.2 SSD isebenzisa isikhuphukeli se-Thermaltech esiguquguqukayo samakhadi wevidiyo asebenza ebhasini le-3.0 ngaphandle kwamaphutha. Kufana nalokhu, okwenziwe “ngamaribhoni” amaningi afana nalawo okwenziwa ngawo izintambo ze-SATA. Izikhuphukeli ze-PCI-E 16x ezenziwe ngekhebula eliyisicaba le-monolithic, elifana nele-IDE-SCSI endala, ziyinhlekelele, zizohlushwa amaphutha ngenxa yokugxambukela. Futhi njengoba ngike ngasho, amaShayina manje nawo enza izikhuphukeli ezifuze nalezo zaseThermaltek, kodwa zibe zifushane.
Ngokuhlanganiswa ne-Tesla K20 + GT 610, ngazama izinto eziningi, ngasikhathi sinye ngathola ukuthi lapho uxhuma ikhadi levidiyo langaphandle futhi ushintsha okukhiphayo kulo ku-BIOS, i-vKVM ayisebenzi, engazange ngempela. ngiphathe kabi. Noma kunjalo, angizange ngihlele ukusebenzisa ividiyo yangaphandle kulolu hlelo, akukho okuphumayo kwevidiyo ku-Teslas, kanye nephaneli yokulawula ekude nge-SSH futhi ngaphandle kwama-X-owls isebenza kahle uma ukhumbula kancane ukuthi uyini umugqa womyalo ngaphandle kwe-GUI. . Kodwa i-IPMI + vKVM ikwenza kube lula ukuphatha, ukufakwa kabusha nezinye izinkinga ngeseva ekude.
Ngokuvamile, i-IPMI yaleli bhodi yinhle. Imbobo ehlukile engu-100 Mbit, ikhono lokuphinda ulungise umjovo wephakethe kwelinye lamachweba angu-10 Gbit, iseva yewebhu eyakhelwe ngaphakathi yokulawula amandla nokulawula amaseva, ukulanda iklayenti le-VKVM Java ngokuqondile kuyo kanye neklayenti lokukhwezwa kude kwamadiski. noma izithombe zokufakwa kabusha... Okuwukuphela kwento ukuthi amaklayenti ayafana ne-Java Oracle endala, engasasekelwa ku-Linux futhi kuphaneli yokulawula ekude kwadingeka ngithole ikhompuyutha ephathekayo ene-Win XP SP3 nalokhu. Ixoxo lasendulo. Hhayi-ke, iklayenti lihamba kancane, kukhona okwanele kwephaneli yomqondisi nakho konke lokho, kodwa awukwazi ukudlala imidlalo ukude, i-FPS incane. Futhi ividiyo ye-ASPEED ehlanganiswe ne-IPMI ayinamandla, i-VGA kuphela.
Enqubweni yokubhekana neseva, ngafunda okuningi futhi ngafunda okuningi emkhakheni we-hardware yeseva yochwepheshe evela kwaDell. Okuyinto engingazisoli ngayo nhlobo, kanye nesikhathi nemali esetshenziswe kahle. Indaba yokufundisa mayelana nokuhlanganisa uhlaka nazo zonke izingxenye zeseva izoqhutshwa kamuva.
