Molo, bahlali abathandekayo baseKhabrovsk!
Ndingathanda ukuqhubeka nebali lam malunga nokudibanisa "ikhompyutha enkulu yelali". Kwaye ndiza kuchaza ukuba kutheni kubizwa njalo-isizathu silula. Mna ngokwam ndihlala ezilalini. Kwaye igama lihamba kancinci kwabo bakhwaza kwi-Intanethi "akukho bomi ngaphaya kweMoscow Ring Road!", "Ilali yaseRussia ibe yinxila kwaye iyafa!" Ke, kwindawo ethile le nto inokuba yinyani, kodwa ndiya kuba ngaphandle kumgaqo. Andiseli, anditshayi, ndenza izinto ezinokuthi azikho zonke "i-cracker (s) zasedolophini". Kodwa makhe sibuyele kwizimvu zethu, okanye ngokuthe ngqo, kumncedisi, lowo ekupheleni kwenxalenye yokuqala yenqaku βeyayibonisa iimpawu zobomi.
Ibhodi yayilele etafileni, ndenyuka nge-BIOS, ndayimisa ngokuthanda kwam, ndatshitshisa Ubuntu 16.04 Desktop ukuze kube lula kwaye ndagqiba ukudibanisa ikhadi levidiyo "kumatshini omkhulu". Kodwa ekuphela kwento ekhoyo yayiyi-GTS 250 ene-hefty non-original fan eqhotyoshelweyo. Endiyifake kwiPCI-E 16x slot kufutshane neqhosha lamandla.
"Ndiyithathile ngepakethi ye-Belomor (c)" ngoko nceda ungandibeki tyala ngomgangatho wesithombe. Ndingathanda ukuphawula malunga noko kufakwe kubo.
Okokuqala, kwavela ukuba xa ifakwe kwi-slot, nokuba ikhadi levidiyo elifutshane liphumla ibhodi ngokuchasene neendawo zokukhumbula imemori, apho kule meko ayikwazi ukufakwa kwaye i-latches kufuneka ithotywe. Okwesibini, umgca wokuxhoma wentsimbi wekhadi levidiyo ugubungela iqhosha lamandla, ngoko ke kwafuneka ukuba lisuswe. Ngendlela, iqhosha lamandla ngokwalo likhanyiswa yi-LED enemibala emibini, ekhanyisa eluhlaza xa yonke into ilungile kwaye iqhwanyaze i-orenji ukuba kukho naziphi na iingxaki, isiphaluka esifutshane kunye nokukhuselwa kombane kuye kwakhubeka okanye amandla +12VSB Unikezelo luphezulu kakhulu okanye luphantsi kakhulu.
Ngapha koko, le bhodi yomama ayenzelwanga ukubandakanya amakhadi evidiyo βngqoβ kwiPCI-E 16x slots; zonke ziqhagamshelwe kwizinyusi. Ukufakela ikhadi lokwandisa kwiindawo zokubeka kufuphi neqhosha lamandla, kukho izinyusi zekona, eziphantsi zokufaka amakhadi amafutshane ukuya kubude be-radiator yeprosesa yokuqala, kunye nekona ephezulu ene-12V yokudibanisa amandla ongezelelweyo ukufakela i-radiator. ikhadi levidiyo "ngaphezulu" umgangatho ophantsi opholileyo we-1U. Ingabandakanya amakhadi amakhulu evidiyo afana ne-GTX 780, i-GTX 980, i-GTX 1080 okanye amakhadi e-GPGPU akhethekileyo Nvidia Tesla K10-K20-K40 okanye "amakhadi e-computing" Intel Xeon Phi 5110p kunye nokunye okunjalo.
Kodwa kwi-GPGPU riser, ikhadi elibandakanyiweyo kwi-EdgeSlot linokudityaniswa ngokuthe ngqo, kuphela ngokuphinda udibanise amandla ongezelelweyo kunye nokudibanisa okufanayo kwikona eliphezulu lokunyuka. Kulabo abanomdla, kwi-eBay le riser eguquguqukayo ibizwa ngokuba yi "Dell PowerEdge C8220X PCI-E GPGPU DJC89" kwaye ixabisa malunga ne-2.5-3 eyiwaka elingangee-ruble. Izinyusi zekona ezinombane owongezelelweyo zinqabile kwaye kuye kwafuneka ndithethathethane ukuze ndizifumane kwivenkile yecandelo leseva elikhethekileyo ngeWhisper. Zixabisa i-7 lamawaka inye.
Ndizakuthi kwangoko, "abafana abasengozini (tm)" banokudibanisa isibini seGTX 980 ebhodini kunye ne-Chinese flexible risers 16x, njengoko umntu omnye wenzayo "kwaloo Forum inye"; ngendlela, amaTshayina enza kakuhle. ubugcisa obuhle obusebenza kwi-PCI-E 16x 2.0 kwisitayile se-Thermaltek flexible ones risers, kodwa ukuba le mini ibangela ukuba utshise iisekethe zamandla kwibhodi yomncedisi, uya kuba netyala. Andizange ndibeke umngcipheko kwizixhobo ezibizayo kwaye ndisebenzise ukunyuka kwasekuqaleni ngamandla angaphezulu kunye nesinye saseTshayina esiguquguqukayo, ndicinga ukuba ukudibanisa ikhadi elinye "ngokuthe ngqo" akuyi kutshisa ibhodi.
Emva koko iziqhagamshelo ekudala zilindelwe zokudibanisa amandla ongezelelweyo zafika kwaye ndenza umsila wokunyuka kwam e-EdgeSlot. Kwaye isinxibelelanisi esifanayo, kodwa ngepinout eyahlukileyo, isetyenziselwa ukubonelela amandla ongezelelweyo kwibhodi yomama. Esi sidibanisi silapha ecaleni kwesi sidibanisi se-EdgeSlot, kukho i-pinout enomdla apho. Ukuba ukunyuka kuneengcingo ezi-2 +12 kunye ne-2 eziqhelekileyo, ke ibhodi ineengcingo ezi-3 +12 kunye ne-1 eqhelekileyo.
Le yi-GTS 250 efanayo equkwe kwisikhuphukeli seGPPU. Ngendlela, amandla ongezelelweyo anikezelwa kwizinyusi kunye nebhodi yomama - ukusuka kwisibini +12V isinxibelelanisi samandla se-CPU yonikezelo lwamandla am. Ndiye ndagqiba kwelokuba kulunge ngakumbi ukwenza oku.
Intsomi izixelela ngokukhawuleza, kodwa ngokuthe ngcembe iipasile zifika eRussia zivela eTshayina nakwezinye iindawo kwihlabathi liphela. Ngoko ke, kwakukho izikhewu ezinkulu kwindibano ye "supercomputer". Kodwa ekugqibeleni iseva yeNvidia Tesla K20M eneradiyetha esebenzayo yafika kum. Ngaphezu koko, i-zero ngokupheleleyo, ukusuka kwisitoreji, itywinwe kwibhokisi yayo yokuqala, kwiphakheji yayo yasekuqaleni, kunye namaphepha ewaranti. Kwaye ukubandezeleka kwaqala: njani ukupholisa?
Okokuqala, i-cooler yesiko kunye "nee-turbines" ezincinci ezimbini zathengwa eNgilani, nantsi ifoto, kunye ne-diffuser yekhadibhodi yasekhaya.
Kwaye kwavela ukuba yimpazamo epheleleyo. Benza ingxolo eninzi, intaba ayizange ifaneleke konke, bavuthela buthathaka kwaye banika ukungcangcazela kangangokuba ndoyika ukuba amacandelo aya kuwa kwibhodi yeTesla! Kwakutheni ukuze balahlwe emgqomeni ngokukhawuleza?
Ngendlela, kwisithombe esiphantsi kweTesla unokubona i-LGA 2011 1U iseva ye-radiator yobhedu efakwe kwiiprosesa kunye nenkumba evela kwi-Coolerserver ethengwe kwi-Aliexpress. Iicoolers ezindilisekileyo, nangona zinengxolo encinci. Zingena ngokugqibeleleyo.
Kodwa eneneni, ngelixa ndilinde i-cooler entsha ye-Tesla, ngeli xesha ndiyalele i-snail enkulu ye-BFB1012EN evela e-Australia ene-3D eprintiweyo entabeni, yafika kwinkqubo yokugcina iseva. Ibhodi yeseva ine-mini-SAS isidibanisi apho i-4 SATA kunye ne-2 ngaphezulu kwe-SATA i-connectors iphuma. Yonke imigangatho yeSATA 2.0 kodwa iyandifanela.
I-intel C602 RAID edibeneyo kwi-chipset ayibi kwaye into ephambili kukuba idlula umyalelo we-TRIM we-SSD, apho abaninzi abalawuli be-RAID bangaphandle abangabizi bangenzi.
Kwi-eBay ndithenge i-mini-long ye-mini-SAS ukuya kwi-4 SATA cable, kwaye kwi-Avito ndithenge inqwelo yokutshintsha okushushu kunye ne-5,25 β³ bay ye-4 x 2,5 β³ SAS-SATA. Ngoko xa ikhebula kunye nebhasikithi yafika, i-4 terabyte Seagates ifakwe kuyo, i-RAID5 yezixhobo ze-4 zakhiwe kwi-BIOS, ndaqalisa ukufaka umncedisi we-Ubuntu ... kwaye ndabalekela kwinto yokuba inkqubo yokwahlula idisk ayizange indivumele. ukwenza isahlulelo sokutshintsha kuhlaselo.
Ndiyisombulule ingxaki ngentloko-ndathenga i-ASUS HYPER M.2 x 2 MINI kunye ne-M.4 SSD i-adapter ye-Samsung 2 EVO 960 Gb esuka kwi-DNS kwaye ndagqiba ekubeni isixhobo esiphezulu sesantya kufuneka sinikezelwe ukutshintshwa, ekubeni inkqubo iya kusebenza. ngomthwalo ophezulu wokubala, kwaye imemori isengaphantsi kobungakanani bedatha. Kwaye imemori ye-250 GB yayibiza kakhulu kune-SSD.
Le iadaptha efanayo kunye ne-SSD efakwe kwikona ephantsi yokunyuka.
Ukulindela imibuzo - "Kutheni ungenzi yonke inkqubo kwi-M.2 kwaye ube nesantya esiphezulu sofikelelo esiphezulu kuneso sohlaselo lwe-SATA?" - Ndiza kuphendula. Okokuqala, i-TB eyi-1 okanye ngaphezulu kwe-M2 SSDs zibiza kakhulu kum. Okwesibini, nasemva kokuhlaziya i-BIOS kuguqulelo lwamva nje lwe-2.8.1, umncedisi akakaxhasi ukulayisha izixhobo ze-M.2 NVE. Ndenze uvavanyo apho inkqubo ibeka / i-boot kwi-USB FLASH 64 Gb kunye nayo yonke into kwi-M.2 SSD, kodwa andizange ndiyithande. Nangona, ngokomgaqo, indibaniselwano enjalo iyasebenza kakhulu. Ukuba umthamo ophezulu we-M.2 NVEs uba nexabiso eliphantsi, ndingabuyela kolu khetho, kodwa okwangoku iSATA RAID njengenkqubo yokugcina indifanela kakuhle.
Xa ndagqiba kwi-subsystem yedisk kwaye ndeza kunye ne-2 x SSD Kingston 240 Gb RAID1 "/" + 4 x HDD Seagate 1 Tb RAID5 "/home" + M.2 SSD Samsung 960 EVO 250 Gb "swap" ixesha lokuqhubeka novavanyo lwam ngeGPU Ndandisele ndine-Tesla kunye ne-cooler yase-Australia esanda kufika kunye ne-snail "embi" edla kakhulu i-2.94A kwi-12V, i-slot yesibini yayibanjwe ngu-M.2 kwaye okwesithathu ndiboleke i-GT 610 "yokulinga."
Apha kwisithombe zonke izixhobo ze-3 zixhunyiwe, kwaye i-M.2 SSD ihamba nge-flexible Thermaltech riser yamakhadi evidiyo asebenza kwibhasi ye-3.0 ngaphandle kweempazamo. Ifana nale, yenziwe "kwiiribhoni" ezininzi ezifanayo nezo zenziwa kuzo iintambo zeSATA. I-PCI-E 16x iziphakamisi ezenziwe kwintambo ye-monolithic flat, uhlobo olufana ne-IDE-SCSI endala, yintlekele, baya kubandezeleka ngenxa yeempazamo ngenxa yokuphazamiseka okufanayo. Kwaye njengoko besenditshilo, amaTshayina ngoku enza izinyusi ezifanayo nezo zeThermaltek, kodwa zifutshane.
Ngokudibanisa neTesla K20 + GT 610, ndazama izinto ezininzi, kwangaxeshanye ndafumanisa ukuba xa udibanisa ikhadi levidiyo langaphandle kwaye utshintshe imveliso kuyo kwiBIOS, i-vKVM ayisebenzi, engazange ngokwenene. ndicaphukise. Nangona kunjalo, andizange ndicwangcise ukusebenzisa ividiyo yangaphandle kule nkqubo, akukho ziphumo zevidiyo kwiTeslas, kunye nephaneli yokulawula ekude nge-SSH kwaye ngaphandle kwe-X-owls isebenza kakuhle xa ukhumbula kancinci ukuba yintoni umgca womyalelo ngaphandle kwe-GUI. . Kodwa IPMI + vKVM ilula kakhulu ulawulo, ukufakwa kwakhona kunye neminye imiba ngeseva ekude.
Ngokubanzi, IPMI yale bhodi inkulu. I-port ye-100 ye-Mbit eyahlukileyo, ukukwazi ukuphinda uqwalasele inaliti yepakethe kwenye yezibuko ze-Gbit ze-10, i-Web server eyakhelwe-ngaphakathi yolawulo lwamandla kunye nokulawulwa kweeseva, ukukhuphela i-vKVM umxhasi weJava ngqo kuyo kunye nomxhasi wokunyuka kweediski ezikude. okanye imifanekiso yokufakwa kwakhona... Into ekuphela kwayo kukuba abathengi bayafana nendala yeJava Oracle, engasaxhaswanga kwi Linux kunye neqela lenjongo yolawulo ekude kuye kwafuneka ndifumane ilaptop nge Win XP SP3 nale kakhulu. Isele yamandulo. Ewe, umxhasi uyacotha, yanele ipaneli yolawulo nayo yonke loo nto, kodwa awukwazi ukudlala imidlalo ukude, i-FPS incinci. Kwaye ividiyo ye-ASPEED edityaniswe ne-IPMI ibuthathaka, i-VGA kuphela.
Kwinkqubo yokujongana nomncedisi, ndafunda okuninzi kwaye ndafunda kakhulu kwintsimi ye-hardware ye-server yobuchwephesha evela kuDell. Into endingazisoli ngayo kwaphela, kunye nexesha kunye nemali esetyenziswe kakuhle. Ibali elifundisayo malunga nokudibanisa isakhelo kunye nawo onke amacandelo omncedisi liza kuqhubeka kamva.
