Huawei OceanStor Dorado 18000 V6: chikhalidwe chake chapamwamba ndi chiyani

Timatsutsana mwatsatanetsatane chomwe chimapangitsa OceanStor Dorado 18000 V6 kukhala njira yosungiramo zosungirako zosungirako zosungirako zaka zikubwerazi. Panthawi imodzimodziyo, timachotsa mantha omwe amapezeka pa All-Flash yosungirako ndikuwonetsa momwe Huawei amafinyira kwambiri: NVMe yotsiriza-kumapeto, caching yowonjezera pa SCM, ndi mulu wa mayankho ena.

Malo atsopano a data - kusungirako deta kwatsopano

Kuchuluka kwa data kukukulirakulira m'mafakitale onse. Ndipo gawo la banki ndi chithunzi chowonekera bwino cha izi. Pazaka zingapo zapitazi, chiwerengero cha mabanki chawonjezeka kupitirira kakhumi. Monga ziwonetsero Maphunziro a BCG, ku Russia kokha mu nthawi ya 2010 mpaka 2018 chiwerengero cha ntchito zopanda ndalama zogwiritsira ntchito makadi apulasitiki zimasonyeza kuwonjezereka kwa makumi atatu - kuchokera 5,8 mpaka 172 pa munthu pachaka. Choyamba, kupambana kwa micropayments: ambiri aife takhala okhudzana ndi kubanki pa intaneti, ndipo banki tsopano ili m'manja mwathu - pafoni.

Zomangamanga za IT za bungwe la ngongole ziyenera kukhala zokonzekera zovuta zotere. Ndipo izi ndizovuta. Mwa zina, ngati poyamba banki imayenera kutsimikizira kupezeka kwa deta panthawi yamalonda, tsopano ndi 24/7. Mpaka posachedwa, 5 ms inkatengedwa ngati mlingo wovomerezeka wa latency, ndiye chiyani? Tsopano ngakhale 1 ms ndiyopambana. Kwa makina osungira amakono, cholinga chake ndi 0,5 ms.

Momwemonso ndi kudalirika: mu 2010, kumvetsetsa kwamphamvu kunakhazikitsidwa kuti ndikokwanira kubweretsa mlingo wake "makumi asanu" - 99,999%. Zowona, kumvetsetsa kumeneku kwatha. Mu 2020, sizachilendo kuti bizinesi ifune 99,9999% kuti isungidwe ndi 99,99999% pazomanga zonse. Ndipo izi sizongofuna konse, koma kufunikira kwachangu: mwina palibe zenera la nthawi yokonza zomangamanga, kapena ndilaling'ono.

Kuti zimveke bwino, ndikosavuta kuyika zizindikiro pa ndege yandalama. Njira yosavuta ndi chitsanzo cha mabungwe azachuma. Tchati pamwambapa chikuwonetsa ndalama zomwe mabanki 10 apamwamba padziko lonse amapeza pa ola limodzi. Kwa Banki ya Industrial and Commercial ya China yokha, izi ndi zosachepera $ 5 miliyoni. Izi ndizofanana ndi kuchuluka kwa ola la nthawi yowonongeka kwa IT zomangamanga za bungwe lalikulu la ngongole ku China (ndipo phindu lotayika lokha likuganiziridwa mu chiŵerengero!). Kuchokera pamalingaliro awa, zikuwonekeratu kuti kuchepetsedwa kwa nthawi yochepetsera ndi kuwonjezeka kwa kudalirika, osati kokha ndi peresenti yochepa, koma ngakhale ndi tizigawo ta peresenti, ndizovomerezeka kwathunthu. Osati kokha pazifukwa zowonjezera mpikisano, koma chifukwa cha kusunga malo amsika.

Kusintha kofananirako kukuchitika m'mafakitale ena. Mwachitsanzo, pamayendedwe apandege: mliri usanachitike, kuyenda pandege kumangokulirakulira chaka ndi chaka, ndipo ambiri adayamba kuzigwiritsa ntchito ngati taxi. Ponena za machitidwe a ogula, chizoloŵezi cha kupezeka kwathunthu kwa mautumiki chakhazikika pakati pa anthu: tikafika pa eyapoti, tifunika kulumikiza ku Wi-Fi, kupeza ntchito zolipirira, kupeza mapu a dera, ndi zina zotero. Zotsatira zake, kuchuluka kwa zomangamanga ndi ntchito m'malo opezeka anthu ambiri kuchulukirachulukira. Ndipo njira zake zogwirira ntchito zake, zomangamanga, zomwe tidaziwona ngati zovomerezeka ngakhale chaka chapitacho, zikutha ntchito.

Kodi ndikoyambika kwambiri kuti musinthe kupita ku All-Flash?

Kuti athetse mavuto omwe tawatchula pamwambapa, pokhudzana ndi ntchito, AFA - mitundu yonse ya flash, ndiko kuti, zojambulajambula zomwe zimamangidwa pa flash - ndizoyenera kwambiri. Pokhapokha, mpaka posachedwa, panali kukayikira ngati angafanane ndi kudalirika ndi omwe adasonkhanitsidwa pamaziko a HDD ndi hybrid. Kupatula apo, memory-state flash memory ili ndi metric yotchedwa mean time between failures, kapena MTBF (kutanthauza nthawi pakati pa zolephera). Kuwonongeka kwa ma cell chifukwa cha ntchito za I / O, tsoka, kumaperekedwa.

Chifukwa chake chiyembekezo cha All-Flash chidaphimbidwa ndi funso la momwe angapewere kutayika kwa data ngati SSD idalamula kuti azikhala kwa nthawi yayitali. Kusunga zosunga zobwezeretsera ndi njira yodziwika bwino, nthawi yokhayo yochira ingakhale yayikulu mosavomerezeka kutengera zofunikira zamakono. Njira ina yotulutsira ndikukhazikitsa gawo lachiwiri losungira pa ma spindle drives, komabe, ndi chiwembu chotere, zina mwazabwino za dongosolo la "flashly flash" zimatayika.

Komabe, manambala amanena mosiyana: ziwerengero za zimphona za chuma cha digito, kuphatikizapo Google, m'zaka zaposachedwa zikuwonetsa kuti kung'anima kumakhala kodalirika kangapo kuposa ma hard drive. Komanso, mu nthawi yochepa komanso yayitali: pafupifupi, zaka zinayi mpaka zisanu ndi chimodzi zimadutsa ma drive a Flash asanalephereke. Pankhani yodalirika yosungiramo deta, iwo sali otsika kuposa ma drive a spindle magnetic disks, kapena kuwaposa.

Mtsutso wina wachikhalidwe wokomera ma spindle drives ndi kukwanitsa kwawo. Mosakayikira, mtengo wosungira terabyte pa hard drive udakali wotsika. Ndipo ngati mungoganizira mtengo wa zida zokha, ndizotsika mtengo kusunga terabyte pa spindle drive kuposa SSD. Komabe, pankhani yakukonzekera ndalama, sizimangotengera kuchuluka kwa chipangizo china chomwe chinagulidwa, komanso ndalama zotani zomwe zimakhala nazo kwa nthawi yayitali - kuyambira zaka zitatu mpaka zisanu ndi ziwiri.

Kuchokera kumbali iyi, ndizosiyana kwambiri. Ngakhale titanyalanyaza kuchotsera ndi kuponderezana, zomwe, monga lamulo, zimagwiritsidwa ntchito pazitsulo zowunikira ndikupangitsa kuti ntchito yawo ikhale yopindulitsa kwambiri pazachuma, pamakhalabe makhalidwe monga rack space yomwe imakhala ndi ma TV, kutaya kutentha, ndi kugwiritsa ntchito mphamvu. Ndipo molingana ndi iwo, kuphulika kumaposa omwe adatsogolera. Zotsatira zake, TCO yamakina osungiramo kung'anima, poganizira magawo onse, nthawi zambiri imakhala pafupifupi theka lazofanana ndi zomwe zimayenderana ndi ma spindle drives kapena ma hybrids.

Malinga ndi malipoti a ESG, makina osungira a Dorado V6 All-Flash amatha kukwaniritsa mtengo wochepetsera umwini mpaka 78% pakadutsa zaka zisanu, kuphatikiza kutsitsa koyenera komanso kukakamiza, komanso chifukwa chogwiritsa ntchito mphamvu pang'ono komanso kutayika kwa kutentha. Kampani yaku Germany yowunikira DCIG imalimbikitsanso kuti agwiritsidwe ntchito ngati abwino kwambiri malinga ndi TCO yomwe ilipo lero.

Kugwiritsiridwa ntchito kwa magalimoto olimba kumapangitsa kuti zitheke kupulumutsa malo ogwiritsidwa ntchito, kuchepetsa chiwerengero cha zolephera, kuchepetsa nthawi yokonza njira yothetsera vutoli, kuchepetsa kugwiritsira ntchito mphamvu ndi kutaya kutentha kwa machitidwe osungira. Ndipo zikuwonekeratu kuti AFA ndiyotsika mtengo poyerekeza ndi miyambo yama spindle drive, ndipo nthawi zambiri imawaposa.

Huawei Royal Flush

Pakati pa zosungira zathu za All-Flash, malo apamwamba ndi a hi-end system OceanStor Dorado 18000 V6. Ndipo osati mwa athu okha: ambiri, mu makampani, ali ndi liwiro mbiri - mpaka 20 miliyoni IPOS mu kasinthidwe pazipita. Kuphatikiza apo, ndizodalirika kwambiri: ngakhale olamulira awiri awuluka nthawi imodzi, kapena olamulira asanu ndi awiri mmodzi pambuyo pa mnzake, kapena injini yonse nthawi imodzi, deta idzapulumuka. Ubwino wokulirapo wa "khumi ndi zisanu ndi zitatu" amaperekedwa ndi AI omwe amalumikizana nawo, kuphatikiza kusinthasintha pakuwongolera njira zamkati. Tiyeni tiwone momwe izi zimakwaniritsidwira.

Mwambiri, Huawei ali ndi chiyambi chifukwa ndiye wopanga yekha pamsika yemwe amapanga makina osungira okha - kwathunthu komanso kwathunthu. Tili ndi zozungulira zathu, ma microcode athu, ntchito zathu.

Woyang'anira mu machitidwe a OceanStor Dorado amamangidwa pa purosesa ya mapangidwe ake a Huawei - Kunpeng 920. Amagwiritsa ntchito gawo lowongolera la Intelligent Baseboard Management Controller (iBMC), komanso lathu. Tchipisi za AI, zomwe ndi Ascend 310, zomwe zimakwaniritsa zolosera zolephera ndikupanga malingaliro pazosintha, ndi Huawei, komanso matabwa a I / O - gawo la Smart I / O. Pomaliza, olamulira mu ma SSD adapangidwa ndikupangidwa ndi ife. Zonsezi zidapereka maziko opangira njira yokhazikika komanso yogwira ntchito kwambiri.

M'chaka chathachi, takhazikitsa ntchito yowonetsera iyi, njira yathu yosungiramo zinthu zapamwamba kwambiri, mu imodzi mwa mabanki akuluakulu a ku Russia. Chotsatira chake, oposa 40 OceanStor Dorado 18000 V6 mayunitsi mu metro tsango amasonyeza ntchito khola: oposa miliyoni IOPS akhoza kuchotsedwa dongosolo lililonse, ndipo izi kuganizira kuchedwa chifukwa cha mtunda.

End-to-End NVMe

Makina aposachedwa a Huawei amathandizira NVMe yomaliza, yomwe timatsindika pazifukwa. Ma protocol omwe amagwiritsidwa ntchito kale kuti apeze ma drive adapangidwa m'nthawi yakale ya IT: amatengera malamulo a SCSI (moni, 1980s!), Zomwe zimakoka ntchito zambiri kuti zitsimikizire kuti zimagwirizana. Kaya mutenge njira yotani yofikira, ma protocol apamwamba pankhaniyi ndiakuluakulu. Zotsatira zake, pazosungira zomwe zimagwiritsa ntchito ma protocol omangidwa ku SCSI, kuchedwa kwa I / O sikungakhale kotsika kuposa 0,4-0,5 ms. Komanso, pokhala protocol yopangidwa kuti igwire ntchito ndi flash memory ndikumasulidwa ku ndodo chifukwa chodziwika bwino kumbuyo, NVMe - Non-Volatile Memory Express - imagwetsa latency ku 0,1 ms, kuwonjezera apo, osati pa yosungirako, koma pa gulu lonse, kuchokera pagulu mpaka ma drive. N'zosadabwitsa kuti NVMe ikugwirizana ndi zomwe zikuchitika m'tsogolomu. Tidadaliranso NVMe - ndipo tikuyenda pang'onopang'ono kuchoka ku SCSI. Makina onse osungira a Huawei omwe amapangidwa lero, kuphatikiza mzere wa Dorado, amathandizira NVMe (komabe, monga kumapeto mpaka kumapeto amangogwiritsidwa ntchito pamitundu yapamwamba ya mndandanda wa Dorado V6).

FlashLink: Fistful of Technologies

Ukadaulo wapangodya wamzere wonse wa OceanStor Dorado ndi FlashLink. Zowonadi, ndi mawu omwe amaphatikiza matekinoloje ophatikizika omwe amatsimikizira kuti magwiridwe antchito ndi odalirika. Izi zikuphatikizapo matekinoloje ochepetsera ndi kuponderezana, kugwira ntchito kwa dongosolo la RAID 2.0+ logawa deta, kulekanitsa deta "yozizira" ndi "yotentha", kujambula kwamtundu wamtundu uliwonse (kulemba mwachisawawa, ndi deta yatsopano ndi yosinthidwa, imaphatikizidwa kukhala gulu lodziwika bwino la deta. stack yayikulu komanso yolembedwa motsatizana, zomwe zimawonjezera liwiro lowerenga).

Mwa zina, FlashLink imaphatikizapo zigawo ziwiri zofunika - Wear Leveling ndi Global Garbage Collection. Ayenera kuchitidwa nawo mosiyana.

Ndipotu, galimoto iliyonse yolimba ndi yosungiramo zinthu zazing'ono, zokhala ndi midadada yambiri ndi wolamulira yemwe amatsimikizira kupezeka kwa deta. Ndipo zimaperekedwa, mwa zina, chifukwa chakuti deta kuchokera ku maselo "ophedwa" amasamutsidwa ku "osaphedwa". Izi zimatsimikizira kuti zitha kuwerengedwa. Pali ma aligorivimu osiyanasiyana pakusintha kotere. Nthawi zambiri, wolamulira amayesa kulinganiza kuvala kwa maselo onse osungira. Njira imeneyi ili ndi kuipa kwake. Deta ikasunthidwa mkati mwa SSD, kuchuluka kwa ma I / O omwe imagwira kumachepetsedwa kwambiri. Pakalipano, ndi choipa chofunikira.

Chifukwa chake, ngati pali ma SSD ambiri m'dongosolo, "mawona" amawoneka pa graph yogwira ntchito, yokhala ndi zokwera komanso zotsika. Vuto ndiloti galimoto imodzi kuchokera padziwe imatha kuyambitsa kusamuka kwa data nthawi iliyonse, ndipo ntchito yonseyo imachotsedwa nthawi imodzi kuchokera ku SSD zonse zomwe zilipo. Koma mainjiniya a Huawei adapeza momwe angapewere "mawona".

Mwamwayi, olamulira onse m'magalimoto, ndi woyang'anira zosungirako, ndi firmware ya Huawei ndi "zabadwidwe", njirazi mu OceanStor Dorado 18000 V6 zimayambitsidwa chapakati, synchronously pa zoyendetsa zonse mumagulu. Komanso, pa lamulo la woyang'anira yosungirako, ndipo ndendende pamene palibe katundu wolemetsa wa I / O.

Chip chanzeru chochita kupanga chimakhudzidwanso posankha nthawi yoyenera kusamutsa deta: kutengera ziwerengero za kugunda kwa miyezi ingapo yapitayo, imatha kuneneratu ndi kuthekera kwakukulu ngati mungayembekezere I / O yogwira posachedwa, ndi ngati yankho liri loipa, ndipo katundu pa dongosolo pakali pano ndi wamng'ono, ndiye wolamulira amalamulira ma drive onse: omwe amafunikira Wear Leveling ayenera kuchita nthawi imodzi ndi synchronously.

Kuphatikiza apo, woyang'anira dongosolo amawona zomwe zikuchitika mu cell iliyonse yagalimoto, mosiyana ndi makina osungira omwe amapanga mpikisano: amakakamizika kugula zofalitsa zolimba kuchokera kwa ogulitsa chipani chachitatu, chifukwa chake mafotokozedwe amtundu wa cell sapezeka. olamulira a zosungira zoterozo.

Zotsatira zake, OceanStor Dorado 18000 V6 ili ndi nthawi yochepa kwambiri ya kuwonongeka kwa ntchito pa Wear Leveling operation, ndipo imachitidwa makamaka pamene sichikusokoneza njira zina zilizonse. Izi zimapereka magwiridwe antchito okhazikika nthawi zonse.

Zomwe Zimapangitsa OceanStor Dorado 18000 V6 kukhala yodalirika

Pali magawo anayi odalirika m'makina amakono osungira deta:

• hardware, pa mlingo woyendetsa;
• zomangamanga, pa mlingo zida;
• zomangamanga pamodzi ndi gawo la mapulogalamu;
• kuchulukana, okhudzana ndi yankho lonse.

Popeza, tikukumbukira, kampani yathu imapanga ndi kupanga zigawo zonse zosungirako zosungirako zokha, timapereka kudalirika pamagulu anayi onsewa, ndikutha kuyang'anitsitsa bwino zomwe zikuchitika pa zomwe zikuchitika panthawiyi.

Kudalirika kwa ma drive kumatsimikiziridwa makamaka ndi Wear Leveling ndi Global Garbage Collection zomwe zafotokozedwa kale. Pamene SSD ikuwoneka ngati bokosi lakuda ku dongosolo, silidziwa momwe maselo amathera mmenemo. Kwa OceanStor Dorado 18000 V6, zoyendetsa zimakhala zowonekera, zomwe zimapangitsa kuti zikhale zotheka kusinthasintha mofanana pamagalimoto onse pamndandanda. Chifukwa chake, zimakulitsa kwambiri moyo wa SSD ndikuteteza kudalirika kwa magwiridwe antchito awo.

Komanso, kudalirika kwa galimotoyo kumakhudzidwa ndi maselo owonjezera owonjezera mmenemo. Ndipo pamodzi ndi malo osungira osavuta, makina osungira amagwiritsa ntchito otchedwa DIF maselo, omwe ali ndi ma checksums, komanso zizindikiro zowonjezera kuti ateteze chipika chilichonse ku cholakwika chimodzi, kuwonjezera pa chitetezo pa mlingo wa RAID.

Chinsinsi cha kudalirika kwa zomangamanga ndi yankho la SmartMatrix. Mwachidule, awa ndi olamulira anayi omwe amakhala pa ndege yobwerera kumbuyo ngati gawo la injini imodzi (injini). Awiri mwa ma injini awa - motsatana, okhala ndi owongolera asanu ndi atatu - amalumikizidwa ndi mashelufu wamba okhala ndi ma drive. Chifukwa cha SmartMatrix, ngakhale olamulira asanu ndi awiri mwa asanu ndi atatu atasiya kugwira ntchito, kupeza deta yonse, powerenga ndi kulemba, kudzakhalabe. Ndipo ndi kutayika kwa owongolera asanu ndi mmodzi mwa asanu ndi atatu, zitha kukhala zotheka kupitiliza ntchito za caching.

Ma board a I / O panjira yofanana yongoyimbayi amapezeka kwa olamulira onse, kutsogolo komanso kumbuyo. Ndi dongosolo lolumikizana ndi ma mesh athunthu, ziribe kanthu zomwe zingalephereke, kupeza ma drive kumasungidwa nthawi zonse.

Ndikoyenera kwambiri kuyankhula za kudalirika kwa zomangamanga pamikhalidwe yolephera yomwe dongosolo losungirako limatha kuteteza.

Kusungirako kudzapulumuka mkhalidwewo popanda kutayika ngati olamulira awiri "agwa", kuphatikizapo nthawi yomweyo. Kukhazikika koteroko kumatheka chifukwa chakuti chipika chilichonse cha cache chili ndi makope ena awiri pa olamulira osiyanasiyana, ndiko kuti, palimodzi palimodzi mu makope atatu. Ndipo osachepera mmodzi ali pa injini ina. Choncho, ngakhale injini yonse itasiya kugwira ntchito - ndi olamulira ake onse anayi - zimatsimikiziridwa kuti zidziwitso zonse zomwe zinali mu kukumbukira kwa cache zidzapulumutsidwa, chifukwa chosungiracho chidzatsatiridwa ndi wolamulira mmodzi kuchokera ku injini yotsalayo. Pomaliza, ndi kulumikizana kwa serial, mutha kutaya mpaka olamulira asanu ndi awiri, ndipo ngakhale atachotsedwa mumagulu awiri, - ndipo kachiwiri, zonse I / O ndi zonse zomwe zasungidwa mu cache zidzasungidwa.

Poyerekeza ndi kusungirako komaliza kuchokera kwa opanga ena, zitha kuwoneka kuti Huawei yekha ndi amene amapereka chitetezo chokwanira cha data ndi kupezeka kwathunthu ngakhale atamwalira olamulira awiri kapena injini yonse. Ogulitsa ambiri amagwiritsa ntchito chiwembu chomwe chimatchedwa ma controller awiri omwe ma drive amalumikizidwa. Tsoka ilo, mu kasinthidwe uku, ngati olamulira awiri alephera, pali chiopsezo chotaya mwayi wa I / O pagalimoto.

Tsoka, kulephera kwa gawo limodzi sikumachotsedwa mwachilungamo. Pachifukwa ichi, ntchitoyo idzatsika kwakanthawi: ndikofunikira kuti njirazo zimangidwenso ndipo mwayi wogwiritsa ntchito I / O uyambitsidwenso pokhudzana ndi midadada yomwe idabwera kudzalemba, koma inali isanalembedwe, kapena idapemphedwa kuti ilembedwe. awerengedwe. OceanStor Dorado 18000 V6 ili ndi nthawi yomanganso pafupifupi sekondi imodzi, yocheperako poyerekeza ndi analogi wapafupi kwambiri pamakampani (4 s). Izi zimatheka chifukwa cha backplane yofananayo: wowongolera akalephera, ena onse amawona nthawi yomweyo zomwe amalowetsa / zotulutsa, makamaka chomwe chipika cha data sichinalembedwe; chifukwa chake, wolamulira wapafupi amatenga ndondomekoyi. Choncho luso kubwezeretsa ntchito mu sekondi chabe. Ndiyenera kuwonjezera, nthawiyo ndi yokhazikika: yachiwiri kwa wolamulira mmodzi, yachiwiri kwa wina, ndi zina zotero.

Mu OceanStor Dorado 18000 V6 passive backplane, matabwa onse amapezeka kwa olamulira onse popanda maadiresi owonjezera. Izi zikutanthauza kuti wowongolera aliyense amatha kunyamula I / O padoko lililonse. Chilichonse chomwe chili kutsogolo kwa I/O chimalowa, wowongolera amakhala wokonzeka kuyikonza. Choncho - chiwerengero chochepa cha kusamutsidwa kwamkati ndi kuphweka kowonekera kwa kusamutsa.

Kuwongolera kutsogolo kumachitika pogwiritsa ntchito dalaivala wochulukirachulukira, ndipo kusanja kwina kukuchitika mkati mwa dongosolo lokha, popeza olamulira onse amawona madoko onse a I / O.

Mwachikhalidwe, magulu onse a Huawei adapangidwa m'njira yoti alibe mfundo imodzi yolephera. Kusinthana kotentha, popanda kuyambiranso dongosolo, kumabwereketsa kuzinthu zake zonse: owongolera, ma module amphamvu, ma module ozizira, matabwa a I / O, ndi zina zambiri.

Imakweza kudalirika kwa dongosolo lonse ndi ukadaulo monga RAID-TP. Ili ndi dzina la gulu la RAID, lomwe limakupatsani mwayi kuti mutsimikizire kulephera munthawi imodzi mpaka ma drive atatu. Ndipo kumangidwanso kwa 1 TB kumatenga mphindi zosakwana 30. Zotsatira zabwino kwambiri zojambulidwa zimathamanga kuwirikiza kasanu ndi kawiri kuposa kuchuluka kwa data pa spindle drive. Chifukwa chake, ndizotheka kugwiritsa ntchito ma drive amphamvu kwambiri, tinene 7,68 kapena 15 TB, osadandaula za kudalirika kwadongosolo.

Ndikofunikira kuti kumangidwanso kuchitidwe osati pagalimoto yopuma, koma m'malo osungira - malo osungira. Aliyense pagalimoto ali odzipereka danga ntchito deta kuchira pambuyo kulephera. Chifukwa chake, kuchira kumachitika osati molingana ndi chiwembu cha "ambiri mpaka amodzi", koma malinga ndi dongosolo la "ambiri mpaka ambiri", chifukwa chake ndizotheka kufulumizitsa kwambiri ntchitoyi. Ndipo malinga ngati pali mphamvu yaulere, kuchira kungapitirire.

Tiyeneranso kutchula kudalirika kwa yankho kuchokera kuzinthu zingapo - mumagulu a metro, kapena, mu terminology ya Huawei, HyperMetro. Mapulani oterowo amathandizidwa pamitundu yonse yachitsanzo cha machitidwe athu osungira deta ndipo amalola mafayilo onse ndi kutsekereza kupeza. Kuphatikiza apo, pa block imodzi, imagwira ntchito zonse kudzera pa Fiber Channel ndi Ethernet (kuphatikiza kudzera pa iSCSI).

M'malo mwake, tikukamba za kubwerezabwereza kwa bidirectional kuchokera ku yosungirako imodzi kupita ku ina, momwe LUN yobwerezedwa imapatsidwa LUN-ID yomweyo monga yaikulu. Ukadaulo umagwira ntchito makamaka chifukwa cha kusasinthika kwa ma cache kuchokera ku machitidwe awiri osiyanasiyana. Chifukwa chake, kwa wolandirayo zilibe kanthu kuti ali mbali iti: apa ndi apo amawona kuyendetsa koyenera komweko. Zotsatira zake, palibe chomwe chimakulepheretsani kuyika gulu la failover lomwe limatenga masamba awiri.

Pa quorum, makina a Linux akuthupi kapena enieni amagwiritsidwa ntchito. Ikhoza kupezeka pa tsamba lachitatu, ndipo zofunikira pazachuma zake ndizochepa. Chochitika chodziwika bwino ndikubwereka tsamba lenileni kuti mugwiritse ntchito VM ya quorum.

Ukadaulowu umalolanso kukulitsa: zosungira ziwiri - mugulu la metro, malo owonjezera - okhala ndi kubwereza kwa asynchronous.

Zakale, makasitomala ambiri apanga "zoo yosungirako": gulu la machitidwe osungiramo zinthu kuchokera kwa opanga osiyanasiyana, zitsanzo zosiyana, mibadwo yosiyanasiyana, ndi ntchito zosiyanasiyana. Komabe, kuchuluka kwa omwe akukhala nawo kungakhale kochititsa chidwi, ndipo nthawi zambiri amakhala okhazikika. Zikatero, chimodzi mwazinthu zofunika kwambiri pakuwongolera ndikupereka mwachangu, mofananira, komanso moyenera ma disks omveka kwa omwe ali ndi makamu, makamaka m'njira yomwe simafufuza komwe ma disks ali. Izi ndizomwe njira yathu ya pulogalamu ya OceanStor DJ idapangidwira, yomwe imatha kuyang'anira machitidwe osiyanasiyana osungira ndikupereka chithandizo kuchokera kwa iwo popanda kulumikizidwa ku mtundu wina wosungira.

AI yemweyo

Monga tanenera kale, OceanStor Dorado 18000 V6 ili ndi mapurosesa opangidwa ndi ma aligorivimu ochita kupanga - Ascend. Amagwiritsidwa ntchito, choyamba, kulosera zolephera, ndipo kachiwiri, kupanga malingaliro akukonzekera, zomwe zimawonjezeranso magwiridwe antchito ndi kudalirika kwa zosungirako.

Zolosera zam'tsogolo ndi miyezi iwiri: Makina a AI amalingalira zomwe zidzachitike ndi mwayi waukulu panthawiyi, kaya ndi nthawi yowonjezera, kusintha ndondomeko zopezera, ndi zina zotero. nthawi.

Gawo lotsatira la chitukuko cha AI kuchokera ku Huawei ndikubweretsa padziko lonse lapansi. Munthawi yokonza ntchito - kulephera kapena malingaliro - Huawei amaphatikiza zidziwitso kuchokera kumakina odula mitengo kuchokera pazosungira zonse zamakasitomala athu. Kutengera zomwe zasonkhanitsidwa, kuwunika kwa zomwe zidachitika kapena zolephera zomwe zingachitike zimachitika ndipo malingaliro apadziko lonse lapansi amapangidwa - osatengera magwiridwe antchito amtundu umodzi wosungira kapena khumi ndi awiri, koma pazomwe zikuchitika ndi zomwe zachitika ndi masauzande otere. zipangizo. Chitsanzocho ndi chachikulu, ndipo kutengera izo, ma algorithms a AI amayamba kuphunzira mwachangu kwambiri, chifukwa chake kulondola kwa maulosi kumawonjezeka kwambiri.

ngakhale

Mu 2019-2020, panali zonena zambiri zokhuza kulumikizana kwa zida zathu ndi zinthu za VMware. Kuti tiwaletse, tikulengeza motsimikiza kuti: VMware ndi mnzake wa Huawei. Mayesero onse omwe angaganizidwe adachitidwa kuti agwirizane ndi hardware yathu ndi mapulogalamu ake, ndipo chifukwa chake, pa webusaiti ya VMware, pepala logwirizana ndi hardware limatchula makina osungira omwe alipo panopa popanda kusungitsa. Mwa kuyankhula kwina, ndi chilengedwe cha mapulogalamu a VMware, mungagwiritse ntchito Huawei yosungirako, kuphatikizapo Dorado V6, ndi chithandizo chonse.
