Tsiku labwino, okondedwa okhala ku Khabrovsk!
Ndikufuna kupitiliza nkhani yanga yokhudza kusonkhanitsa "kompyuta yayikulu yakumudzi". Ndipo ndikufotokozera chifukwa chake imatchedwa choncho-chifukwa chake ndi chophweka. Inenso ndimakhala kumudzi. Ndipo dzinali ndikungoyenda pang'ono kwa iwo omwe amafuula pa intaneti "Palibe moyo wopitilira Moscow Ring Road!", "Mudzi waku Russia wakhala chidakwa ndipo ukumwalira!" Kotero, kwinakwake izi zikhoza kukhala zoona, koma ine ndidzakhala wosiyana ndi lamulo. Sindimwa mowa, sindisuta fodya, ndimachita zinthu zomwe si "zakudya zam'tawuni" zonse zomwe zingakwanitse. Koma tiyeni tibwerere ku nkhosa zathu, kapena momvekera bwino kwambiri, kwa wotumikira, amene kumapeto kwa mbali yoyamba ya nkhaniyo anali kale βkusonyeza zizindikiro za moyo.β
Gululo linali litagona patebulo, ndinakwera kupyolera mu BIOS, ndikuyiyika momwe ndimakonda, ndinachotsa Ubuntu 16.04 Desktop kuti ikhale yosavuta ndipo ndinaganiza zogwirizanitsa khadi la kanema ku "makina apamwamba". Koma chinthu chokhacho chinali pafupi ndi GTS 250 yokhala ndi fan yolimba yomwe siinayambike. Zomwe ndidaziyika mu PCI-E 16x slot pafupi ndi batani lamphamvu.
"Ndinatenga ndi paketi ya Belomor (c)" kotero chonde musandiimbe mlandu chifukwa cha chithunzicho. Ndibwino kuti ndifotokoze zomwe zalembedwa pa iwo.
Choyamba, zidapezeka kuti ikayikidwa mu slot, ngakhale vidiyo yayifupi imayika bolodi motsutsana ndi mipata yokumbukira, momwemo siyingayikidwe ndipo ngakhale zingwe ziyenera kutsitsidwa. Kachiwiri, chingwe choyika chitsulo cha khadi la kanema chimakwirira batani lamphamvu, chifukwa chake chimayenera kuchotsedwa. Mwa njira, batani lamphamvu palokha limawunikiridwa ndi ma LED amitundu iwiri, omwe amawunikira zobiriwira zonse zikakhala bwino ndikuthwanima lalanje ngati pali zovuta, kagawo kakang'ono komanso chitetezo chamagetsi chatsika kapena mphamvu + 12VSB. kupezeka ndikwambiri kapena kutsika kwambiri.
M'malo mwake, bolodiloyi silinapangidwe kuti liphatikize makadi a kanema "mwachindunji" mumipata yake ya PCI-E 16x; onse amalumikizidwa ndi zokwera. Kuti muyike khadi yowonjezera m'mipata yomwe ili pafupi ndi batani lamagetsi, pali zokwera pamakona, yotsika kwambiri yoyika makadi afupiafupi mpaka kutalika kwa radiator yoyamba ya purosesa, ndi ngodya yapamwamba yokhala ndi cholumikizira mphamvu + 12V yowonjezera. Khadi la kanema "pamwamba" lozizira kwambiri la 1U. Itha kuphatikiza makadi akulu a kanema ngati GTX 780, GTX 980, GTX 1080 kapena makadi apadera a GPGPU a Nvidia Tesla K10-K20-K40 kapena "makadi apakompyuta" Intel Xeon Phi 5110p ndi zina zotero.
Koma mu GPGPU riser, khadi yophatikizidwa mu EdgeSlot ikhoza kulumikizidwa mwachindunji, pokhapokha polumikizanso mphamvu zowonjezera ndi cholumikizira chofanana ndi chokwera pamakona apamwamba. Kwa iwo omwe ali ndi chidwi, pa eBay chokwera chosinthika ichi chimatchedwa "Dell PowerEdge C8220X PCI-E GPGPU DJC89" ndipo imawononga pafupifupi ma ruble 2.5-3 zikwi. Zokwera pamakona zokhala ndi magetsi owonjezera ndizosowa kwambiri ndipo ndimayenera kukambirana kuti ndiwapeze kuchokera kusitolo yapaderadera yama seva kudzera pa Whisper. Amawononga 7 iliyonse.
Ndidzati nthawi yomweyo, "anyamata owopsa (tm)" amatha kulumikiza GTX 980 ku bolodi ndi Chinese flexible risers 16x, monga munthu m'modzi adachitira pa "Forum Yemweyo"; mwa njira, aku China amapanga kwambiri. zaluso zabwino zomwe zimagwira ntchito pa PCI-E 16x 2.0 mwanjira ya Thermaltek flexible ones risers, koma ngati tsiku lina likukupangitsani kuti muwotche mabwalo amagetsi pa board ya seva, mungodziimba mlandu. Sindinaike pangozi zida zamtengo wapatali ndipo ndinagwiritsa ntchito zokwera zoyamba ndi mphamvu zowonjezera ndi chimodzi cha China chosinthika, ndikuganiza kuti kulumikiza khadi limodzi "mwachindunji" sikungawotche bolodi.
Kenako zolumikizira zomwe zikuyembekezeredwa kwanthawi yayitali zolumikizira mphamvu zowonjezera zidafika ndipo ndidapanga mchira wokwera wanga ku EdgeSlot. Ndipo cholumikizira chomwecho, koma chokhala ndi pinout yosiyana, chimagwiritsidwa ntchito kupereka mphamvu zowonjezera pa bolodilo. Cholumikizira ichi chili pafupi ndi cholumikizira chomwechi cha EdgeSlot, pali pinout yosangalatsa pamenepo. Ngati chokwera chili ndi mawaya awiri +2 ndi 12 wamba, ndiye kuti bolodi ili ndi mawaya atatu +2 ndi 3 wamba.
Izi ndizofanana ndi GTS 250 zomwe zikuphatikizidwa mu GPGPU riser. Mwa njira, mphamvu zowonjezera zimaperekedwa kwa zokwera ndi bolodi - kuchokera pa cholumikizira chachiwiri cha + 12V cha CPU yamagetsi anga. Ndinaganiza kuti kuchita zimenezi kungakhale koyenera.
Nthanoyi imadziuza yokha mwachangu, koma pang'onopang'ono maphukusi amafika ku Russia kuchokera ku China ndi malo ena padziko lonse lapansi. Chifukwa chake, pagulu la "supercomputer" panali mipata yayikulu. Koma potsiriza seva ya Nvidia Tesla K20M yokhala ndi radiator yokhazikika idafika kwa ine. Komanso, ndi zero mwamtheradi, kuchokera ku yosungirako, yosindikizidwa mu bokosi lake loyambirira, mu phukusi lake loyambirira, ndi mapepala a chitsimikizo. Ndipo kuzunzika kunayamba: momwe mungaziziritsire?
Choyamba, chozizira chozizira chokhala ndi "ma turbine" awiri ang'onoang'ono chinagulidwa kuchokera ku England, apa chiri pa chithunzi, chokhala ndi makina opangira makatoni.
Ndipo zidakhala zopanda pake. Anapanga phokoso lalikulu, phirilo silinagwirizane konse, linawombera mofooka ndikupereka kugwedezeka kotero kuti ndinkaopa kuti zigawozo zidzagwa pa bolodi la Tesla! Nβchifukwa chiyani anawataya mβzinyalala nthawi yomweyo?
Mwa njira, mu chithunzi chomwe chili pansi pa Tesla mutha kuwona ma radiator amkuwa a LGA 2011 1U omwe adayikidwa pa mapurosesa ndi nkhono kuchokera ku Coolerserver yogulidwa ku Aliexpress. Zozizira kwambiri, ngakhale phokoso pang'ono. Zimagwirizana mwangwiro.
Koma kwenikweni, pamene ndinali kuyembekezera kuzizira kwatsopano kwa Tesla, nthawi ino nditalamula nkhono yaikulu ya BFB1012EN kuchokera ku Australia yokhala ndi phiri losindikizidwa la 3D, inafika ku makina osungira seva. Bolodi la seva lili ndi cholumikizira cha mini-SAS chomwe 4 SATA ndi zolumikizira 2 zina za SATA zimatuluka. Zonse za SATA 2.0 koma zimandikwanira.
Intel C602 RAID yophatikizidwa mu chipset sizoyipa ndipo chachikulu ndikuti imadumpha lamulo la TRIM la SSD, zomwe olamulira ambiri otsika mtengo akunja samachita.
Pa eBay ndinagula chingwe chachitali cha mita-SAS kupita ku 4 SATA, ndipo pa Avito ndinagula ngolo yotentha yotentha yokhala ndi 5,25 β³ bay kwa 4 x 2,5 β³ SAS-SATA. Kotero pamene chingwe ndi dengu zinafika, 4 terabyte Seagates anayikidwa mmenemo, RAID5 kwa zipangizo 4 zinamangidwa mu BIOS, ndinayamba kukhazikitsa seva Ubuntu ... kupanga chigawo chosinthana pa kuukira.
Ndinathetsa vutoli molunjika - ndinagula adaputala ya ASUS HYPER M.2 x 2 MINI ndi M.4 SSD Samsung 2 EVO 960 Gb kuchokera ku DNS ndipo ndinaganiza kuti chipangizo chothamanga kwambiri chiyenera kuperekedwa kuti chisinthidwe, popeza dongosolo lidzagwira ntchito. ndi katundu wochuluka wowerengera, ndipo kukumbukira kumakhalabe kochepa kusiyana ndi kukula kwa deta. Ndipo kukumbukira kwa 250 GB kunali kokwera mtengo kuposa SSD iyi.
Adaputala yomweyo yokhala ndi SSD yoyikidwa muchokwera pamakona otsika.
Kuyembekezera mafunso - "Bwanji osapanga dongosolo lonse pa M.2 ndikukhala ndi liwiro lalikulu kuposa la kuukira kwa SATA?" - Ndiyankha. Choyamba, 1 TB kapena kuposa M2 SSDs ndi okwera mtengo kwambiri kwa ine. Kachiwiri, ngakhale mutasintha BIOS ku mtundu waposachedwa wa 2.8.1, seva sichikuthandizira kutsitsa zida za M.2 NVE. Ndinachita kuyesera kumene dongosolo linakhazikitsa / boot ku USB FLASH 64 Gb ndi china chirichonse ku M.2 SSD, koma sindinachikonde. Ngakhale, kwenikweni, kuphatikiza koteroko ndi kothandiza kwambiri. Ngati ma M.2 NVE okwera mtengo atakhala otsika mtengo, nditha kubwereranso kunjira iyi, koma pakadali pano SATA RAID monga makina osungira amandikwanira bwino.
Nditasankha pa disk subsystem ndipo ndinabwera ndi kuphatikiza kwa 2 x SSD Kingston 240 Gb RAID1 "/" + 4 x HDD Seagate 1 Tb RAID5 "/home" + M.2 SSD Samsung 960 EVO 250 Gb "kusinthana" ndi nthawi yoti ndipitirize kuyesa kwanga ndi GPU Ndinali kale ndi Tesla ndi ozizira ku Australia atangofika kumene ndi nkhono "zoipa" zomwe zimadya monga 2.94A pa 12V, kagawo kachiwiri kamakhala ndi M.2 ndipo chachitatu ndinabwereka GT 610 "zoyesera."
Pano pachithunzichi zipangizo zonse za 3 zimagwirizanitsidwa, ndipo M.2 SSD imadutsa pamtunda wosinthika wa Thermaltech kwa makadi a kanema omwe amagwira ntchito pa basi ya 3.0 popanda zolakwika. Zili ngati izi, zopangidwa kuchokera ku "nthiti" zambiri zofanana ndi zomwe zingwe za SATA zimapangidwa. Ma PCI-E 16x okwera opangidwa kuchokera ku chingwe chathyathyathya cha monolithic, chofanana ndi akale a IDE-SCSI, ndi tsoka, adzavutika ndi zolakwika chifukwa chosokonezana. Ndipo monga ndanenera kale, aku China tsopano akupanganso zokwera zofanana ndi za Thermaltek, koma zazifupi.
Kuphatikiza ndi Tesla K20 + GT 610, ndinayesa zinthu zambiri, nthawi yomweyo ndinapeza kuti polumikiza khadi lakunja la kanema ndikusintha zomwe zimachokera ku BIOS, vKVM siigwira ntchito, zomwe sizinali choncho. kundikhumudwitsa. Komabe, sindinakonzekere kugwiritsa ntchito kanema wakunja pamakinawa, palibe zotuluka pavidiyo pa Teslas, ndi gulu lakutali loyang'anira kudzera pa SSH ndipo popanda X-kadzidzi zimagwira ntchito bwino mukakumbukira pang'ono zomwe mzere wopanda GUI uli. . Koma IPMI + vKVM imathandizira kwambiri kasamalidwe, kuyikanso ndi zovuta zina ndi seva yakutali.
Nthawi zambiri, IPMI ya board iyi ndiyabwino. Doko losiyana la 100 Mbit, kuthekera kokonzanso jekeseni wa paketi ku imodzi mwa madoko a 10 Gbit, seva yokhazikika ya Webusaiti yowongolera mphamvu ndi kuwongolera ma seva, kutsitsa kasitomala wa vKVM Java molunjika kuchokera pamenepo ndi kasitomala wokweza ma disks akutali. kapena zithunzi zokhazikitsiranso... Chokhacho ndi chakuti makasitomala ali ofanana ndi Java Oracle yakale, yomwe siinagwiritsidwenso ntchito ku Linux ndi gulu lakutali la admin ndinayenera kupeza laputopu ndi Win XP SP3 ndi izi. Achule akale. Chabwino, kasitomala akuchedwa, pali zokwanira kwa gulu la admin ndi zonsezo, koma simungathe kusewera masewera patali, FPS ndi yaying'ono. Ndipo kanema ya ASPEED yomwe ikuphatikizidwa ndi IPMI ndi yofooka, VGA yokha.
Pogwira ntchito ndi seva, ndinaphunzira zambiri ndipo ndinaphunzira zambiri mu gawo la hardware ya akatswiri a seva kuchokera ku Dell. Zomwe sindimanong'oneza nazo bondo konse, komanso nthawi ndi ndalama zomwe zidagwiritsidwa ntchito bwino. Nkhani yophunzitsa za kusonkhanitsa chimango ndi zigawo zonse za seva idzapitirizidwa mtsogolo.
