Moni, owerenga a Habr. Ndi nkhaniyi tikutsegula mndandanda womwe udzalankhula za hyperconverged system AERODISK vAIR yomwe tapanga. Poyamba, tinkafuna kunena zonse za zonse zomwe zili m'nkhani yoyamba, koma dongosololi ndi lovuta kwambiri, choncho tidzadya njovu m'magawo.
Tiyeni tiyambe nkhani ndi mbiri ya kulengedwa kwa dongosolo, fufuzani mu fayilo ya ARDFS, yomwe ili maziko a vAIR, ndikulankhulanso pang'ono za momwe yankho ili likukhalira pamsika wa Russia.
M'nkhani zamtsogolo tidzakambirana mwatsatanetsatane zamagulu osiyanasiyana omanga (gulu, hypervisor, load balancer, monitoring system, etc.), ndondomeko ya kasinthidwe, kukweza malayisensi, kuwonetsa padera mayesero owonongeka ndipo, ndithudi, lembani za kuyezetsa katundu ndi kukula. Tiperekanso nkhani ina ku mtundu wa vAIR.
Kodi Aerodisk ndi nkhani yokhudza zosungirako? Kapena chifukwa chiyani tinayamba kuchita hyperconvergence poyambirira?
Poyambirira, lingaliro lopanga hyperconvergence yathu linabwera kwa ife kwinakwake cha m'ma 2010. Panthawiyo, panalibe Aerodisk kapena njira zofananira (zamalonda zamagulu a hyperconverged) pamsika. Ntchito yathu inali iyi: kuchokera ku seti ya ma seva omwe ali ndi ma disks am'deralo, ogwirizanitsidwa ndi cholumikizira kudzera pa protocol ya Ethernet, kunali koyenera kupanga chosungirako chowonjezera ndikuyambitsa makina enieni ndi mapulogalamu apakompyuta kumeneko. Zonsezi zinayenera kukhazikitsidwa popanda njira zosungirako (chifukwa kunalibe ndalama zosungiramo zosungirako ndi zida zake, ndipo tinali tisanapange zosungira zathu).
Tinayesa njira zambiri zotseguka ndipo potsiriza tinathetsa vutoli, koma yankho linali lovuta kwambiri komanso lovuta kubwereza. Kupatula apo, yankho ili linali m'gulu la "Kodi limagwira ntchito? Osagwira! Chifukwa chake, titathetsa vutolo, sitinapitirize lingaliro lakusintha zotsatira za ntchito yathu kukhala chinthu chokwanira.
Pambuyo pa chochitikacho, tinachoka pa lingaliro ili, koma tinali ndi malingaliro akuti vutoli linali lotha kuthetsedwa, ndipo ubwino wa yankho loterolo unali wochuluka kuposa zoonekeratu. Pambuyo pake, zotulutsidwa za HCI zamakampani akunja zimangotsimikizira izi.
Choncho, m'katikati mwa 2016, tinabwerera ku ntchitoyi monga gawo la kupanga mankhwala odzaza. Panthawiyo tinalibe ubale uliwonse ndi osunga ndalama, choncho tinayenera kugula sitendi yachitukuko ya ndalama zathu zomwe sizinali zazikulu kwambiri. Titasonkhanitsa ma seva ogwiritsidwa ntchito ndi ma switch pa Avito, tidayamba bizinesi.
Ntchito yayikulu yoyambira inali kupanga zathu, ngakhale zosavuta, koma fayilo yathu, yomwe imatha kugawa deta molingana ndi mawonekedwe a midadada pa nambala ya nth ya ma cluster node, omwe amalumikizidwa ndi cholumikizira kudzera pa Ethernet. Panthawi imodzimodziyo, FS iyenera kukula bwino komanso mosavuta komanso kukhala osadalira machitidwe oyandikana nawo, i.e. kukhala otalikirana ndi VAIR monga "malo osungirako".
Lingaliro loyamba la vAIR
Tinasiya dala kugwiritsa ntchito njira zotsegulira zokonzekera kukonza zosungirako zotambasula (ceph, gluster, luster ndi zina zotero) pofuna chitukuko chathu, popeza tinali nawo kale ntchito zambiri. Zachidziwikire, mayankhowo ndi abwino kwambiri, ndipo tisanagwire ntchito pa Aerodisk, tidakhazikitsa nawo ma projekiti angapo ophatikiza. Koma ndi chinthu chimodzi kukhazikitsa ntchito yeniyeni kwa kasitomala m'modzi, ogwira ntchito pamaphunziro, ndipo, mwina, kugula chithandizo cha ogulitsa wamkulu, ndi chinthu chinanso kupanga chinthu chopangidwa mosavuta chomwe chidzagwiritsidwe ntchito zosiyanasiyana, zomwe ife, monga wogulitsa, mwina ngakhale kudziwa za ife sitidzatero. Chifukwa chachiwiri, zinthu zomwe zinalipo zotseguka sizinali zoyenera kwa ife, choncho tinaganiza zopanga fayilo yogawidwa tokha.
Zaka ziwiri pambuyo pake, omanga angapo (omwe adaphatikiza ntchito pa vAIR ndi ntchito pa makina osungiramo Engine) adapeza zotsatira zina.
Pofika chaka cha 2018, tinali titalemba mafayilo osavuta ndikuwonjezera ndi zida zofunika. Dongosololi limaphatikiza ma disks akuthupi (ako) kuchokera ku maseva osiyanasiyana kupita ku dziwe limodzi lathyathyathya kudzera pa cholumikizira chamkati ndi "kuwadula" kukhala midadada, kenako zida zotchinga zokhala ndi milingo yosiyanasiyana yololera zolakwika zidapangidwa kuchokera ku midadada yeniyeni, pomwe zowoneka bwino zidapangidwa. ndi kuphedwa pogwiritsa ntchito magalimoto a KVM hypervisor.
Sitinavutike kwambiri ndi dzina la fayilo ndikuyitcha kuti ARDFS (taganizirani zomwe imayimira))
Chitsanzochi chinkawoneka bwino (osati chowoneka, ndithudi, panalibe mawonekedwe owoneka) ndipo chinasonyeza zotsatira zabwino ponena za machitidwe ndi makulitsidwe. Pambuyo pa zotsatira zenizeni zoyamba, tinayambitsa ntchitoyi, tikukonzekera malo otukuka komanso gulu losiyana lomwe limagwira ntchito ndi vAIR.
Pofika nthawi imeneyo, kamangidwe kake ka yankholo kadakula, komwe sikunasinthebe kwambiri.
Kulowa mu fayilo ya ARDFS
ARDFS ndiye maziko a vAIR, omwe amapereka kugawidwa, kusungidwa kwa data kosalekeza pagulu lonse. Chimodzi mwa (koma osati chokha) chodziwika bwino cha ARDFS ndikuti sichigwiritsa ntchito ma seva odzipatulira owonjezera a metadata ndi kasamalidwe. Izi poyamba zidapangidwa kuti zichepetse kasinthidwe ka yankho komanso kudalirika kwake.
Mapangidwe osungira
M'magulu onse a gululo, ARDFS imapanga dziwe lomveka kuchokera kumalo onse a disk omwe alipo. Ndikofunika kumvetsetsa kuti dziwe silinafikebe deta kapena malo opangidwa, koma kungoyika, i.e. Node zilizonse zokhala ndi vAIR zoyikidwa, zikawonjezeredwa kumaguluwo, zimangowonjezeredwa ku dziwe la ARDFS lomwe limagawidwa ndipo zida za diski zimagawidwa pagulu lonse (ndipo zopezeka kusungirako zamtsogolo). Njirayi imakupatsani mwayi wowonjezera ndikuchotsa ma node pa ntchentche popanda kukhudza kwambiri dongosolo lomwe likuyenda kale. Iwo. dongosolo ndi losavuta kukulitsa "mu njerwa", kuwonjezera kapena kuchotsa node mu masango ngati kuli kofunikira.
Ma disks owoneka bwino (zinthu zosungira makina enieni) amawonjezedwa pamwamba pa dziwe la ARDFS, lomwe limamangidwa kuchokera ku midadada pafupifupi 4 megabytes kukula. Ma disks enieni amasunga deta. Chiwembu chololera cholakwika chimayikidwanso pamlingo wa disk.
Monga momwe mungaganizire kale, pakulekerera zolakwika za disk subsystem, sitigwiritsa ntchito lingaliro la RAID (Redundant array of independent Disks), koma gwiritsani ntchito RAIN (Redundant array of independent Node). Iwo. Kulekerera kwa zolakwika kumayesedwa, kumangochitika zokha, ndikuyendetsedwa kutengera ma node, osati ma disks. Ma disks, ndithudi, ndi chinthu chosungirako, iwo, monga china chirichonse, amayang'aniridwa, mukhoza kuchita nawo ntchito zonse zokhazikika, kuphatikizapo kusonkhanitsa hardware RAID ya m'deralo, koma gululi limagwira ntchito makamaka pa node.
M'malo omwe mukufunadi RAID (mwachitsanzo, zochitika zomwe zimathandizira zolephera zingapo pamagulu ang'onoang'ono), palibe chomwe chimakulepheretsani kugwiritsa ntchito owongolera a RAID am'deralo, ndikumanga zosungirako zotambasulidwa ndi zomangamanga za RAIN pamwamba. Izi ndizochitika ndipo tikuthandizidwa ndi ife, kotero tikambirana m'nkhani yokhudzana ndi momwe mungagwiritsire ntchito vAIR.
Zosungira Zowonongeka Zosungirako Zosungira
Pakhoza kukhala njira ziwiri zololera zolakwika za ma disks enieni mu vAIR:
1) Chinthu chobwerezabwereza kapena kungobwerezabwereza - njira iyi yololera zolakwika ndi yosavuta ngati ndodo ndi chingwe. Kubwereza kwa synchronous kumachitika pakati pa mfundo ndi chinthu cha 2 (2 makope pamagulu) kapena 3 (makopi atatu, motsatana). RF-3 imalola disk kuti ipirire kulephera kwa mfundo imodzi m'gulu, koma "idya" theka la voliyumu yothandiza, ndipo RF-2 idzapirira kulephera kwa ma node a 3 mumagulu, koma imasungira 2/2 ya voliyumu yothandiza pazosowa zake. Chiwembuchi ndi chofanana kwambiri ndi RAID-3, ndiko kuti, disk yeniyeni yokhazikitsidwa mu RF-1 imagonjetsedwa ndi kulephera kwa node iliyonse mumagulu. Pankhaniyi, zonse zidzakhala bwino ndi deta ndipo ngakhale I / O siidzatha. Node yogwa ikabwerera kuntchito, kuyambiranso / kugwirizanitsa deta kudzayamba.
Pansipa pali zitsanzo za kugawa kwa data ya RF-2 ndi RF-3 mumayendedwe abwinobwino komanso pakulephera.
Tili ndi makina enieni omwe ali ndi mphamvu ya 8MB ya deta yapadera (yothandiza), yomwe imayenda pa 4 vAIR node. Zikuwonekeratu kuti kwenikweni sizingatheke kuti padzakhala voliyumu yaying'ono, koma kwa chiwembu chomwe chikuwonetsa malingaliro a ntchito ya ARDFS, chitsanzo ichi ndichomveka kwambiri. AB ndi midadada ya 4MB yokhala ndi data yapadera yamakina. RF-2 imapanga makope awiri a midadada A1 + A2 ndi B1 + B2, motsatana. Mipiringidzo iyi "yayalidwa" kudutsa ma node, kupeΕ΅a kuphatikizika kwa deta yomweyi pamfundo yomweyi, ndiye kuti, kukopera A1 sikudzakhala pamfundo yofanana ndi A2. Zomwezo ndi B1 ndi B2.
Ngati imodzi mwa node ikulephera (mwachitsanzo, node No. 3, yomwe ili ndi kopi ya B1), kopeli limangotsegulidwa pa node pomwe palibe kopi yake (ndiko kuti, kopi ya B2).
Chifukwa chake, disk yeniyeni (ndi VM, molingana) imatha kupulumuka kulephera kwa node imodzi mu RF-2 chiwembu.
Chiwembu chobwerezabwereza, ngakhale chosavuta komanso chodalirika, chimakhala ndi vuto lofanana ndi RAID1 - malo osakwanira ogwiritsira ntchito.
2) Fufutani khodi kapena kufufuta khodi (yomwe imatchedwanso "redundant coding", "erasure coding" kapena "redundancy code") ilipo kuti athetse vuto lomwe lili pamwambapa. EC ndi dongosolo la redundancy lomwe limapereka kupezeka kwakukulu kwa deta ndi malo otsika a disk pamwamba poyerekeza ndi kubwereza. Mfundo yogwiritsira ntchito makinawa ndi ofanana ndi RAID 5, 6, 6P.
Pamene encoding, ndi EC ndondomeko amagawa chipika pafupifupi (4MB mwa kusakhulupirika) mu angapo ang'onoang'ono "data chunks" malinga ndi EC chiwembu (mwachitsanzo, 2+1 chiwembu amagawa aliyense chipika 4MB mu 2 2MB chunks). Kenako, njirayi imapanga "maparity chunks" a "ma data chunks" omwe sali okulirapo kuposa gawo limodzi lomwe lagawidwa kale. Polemba, EC imapanga zinthu zomwe zikusowa powerenga "zotsalira" pamagulu onse.
Mwachitsanzo, disk yeniyeni yokhala ndi dongosolo la 2 + 1 EC, yokhazikitsidwa pa 4 cluster node, idzapirira mosavuta kulephera kwa node imodzi mumagulu mofanana ndi RF-2. Pankhaniyi, mtengo wapamutu udzakhala wotsika, makamaka, mphamvu yothandiza ya RF-2 ndi 2, ndipo EC 2 + 1 idzakhala 1,5.
Kuti tifotokoze mophweka, chofunika kwambiri ndi chakuti chipikacho chimagawidwa kukhala 2-8 (chifukwa chiyani kuchokera 2 mpaka 8, onani pansipa) "zidutswa", ndipo pazidutswa "zidutswa" za kufanana kwa voliyumu yofanana zimawerengedwa.
Zotsatira zake, deta ndi kufanana zimagawidwa mofanana pamagulu onse a gululo. Nthawi yomweyo, monga kubwerezabwereza, ARDFS imagawira deta pakati pa ma node m'njira yotetezera deta yofanana (makopi a deta ndi kufanana kwawo) kuti asasungidwe pamfundo yomweyi, kuti athetse mwayi wotaya deta chifukwa ku mfundo yakuti deta ndi kufanana kwawo zidzatha mwadzidzidzi pa malo amodzi osungira omwe amalephera.
Pansipa pali chitsanzo, ndi makina ofanana a 8 MB ndi mfundo za 4, koma ndi ndondomeko ya EC 2 + 1.
Mitako A ndi B imagawidwa mu zidutswa ziwiri za 2 MB iliyonse (ziwiri chifukwa 2+1), ndiko kuti, A1+A2 ndi B1+B2. Mosiyana ndi chifaniziro, A1 si kopi ya A2, ndi chipika A, chogawidwa mu magawo awiri, mofanana ndi chipika B. Pazonse, timapeza magulu awiri a 4MB, omwe ali ndi zidutswa ziwiri za MB. Chotsatira, pamtundu uliwonse wa setizi, kufanana kumawerengedwa ndi voliyumu yosaposa chidutswa chimodzi (ie 2 MB), timapeza zowonjezera + 2 zidutswa za parity (AP ndi BP). Pazonse tili ndi 4 Γ 2 deta + 2 Γ 2 parity.
Kenaka, zidutswazo "zimayikidwa" pakati pa node kuti deta isagwirizane ndi kufanana kwawo. Iwo. A1 ndi A2 sizikhala pamfundo yofanana ndi AP.
Pakachitika kulephera kwa mfundo imodzi (mwachitsanzo, komanso yachitatu), chipika chakugwa B1 chidzabwezeretsedwanso kuchokera ku BP parity, yomwe imasungidwa pa node No. palibe B-parity, i.e. gawo la BP. Mu chitsanzo ichi, iyi ndi mfundo No
Ndikukhulupirira kuti wowerenga ali ndi funso:
"Chilichonse chomwe mwafotokoza chakhala chikugwiritsidwa ntchito ndi omwe akupikisana nawo komanso mayankho otseguka, pali kusiyana kotani pakati pa kukhazikitsa kwanu EC mu ARDFS?"
Ndiyeno padzakhala zinthu zosangalatsa za ARDFS.
Fufutani khodi molunjika ku kusinthasintha
Poyamba, tidapereka dongosolo la EC X + Y losavuta, pomwe X ndi yofanana ndi nambala kuyambira 2 mpaka 8, ndipo Y ndi yofanana ndi nambala kuyambira 1 mpaka 8, koma nthawi zonse yocheperako kapena yofanana ndi X. Chiwembuchi chimaperekedwa. kwa kusinthasintha. Kuchulukitsa kuchuluka kwa zidutswa za data (X) komwe chipikacho chimagawika kumathandizira kuchepetsa ndalama zochulukirapo, ndiko kuti, kuwonjezera malo ogwiritsira ntchito.
Kuchulukitsa kuchuluka kwa ma parity chunks (Y) kumawonjezera kudalirika kwa disk yeniyeni. Kukula kwa mtengo wa Y, m'pamenenso ma node ambiri mumagulu amatha kulephera. Zoonadi, kuwonjezera kuchuluka kwa voliyumu kumachepetsa kuchuluka kwa mphamvu zogwiritsidwa ntchito, koma izi ndi mtengo wolipirira kudalirika.
Kudalira kwa magwiridwe antchito a mabwalo a EC ndi pafupifupi molunjika: "zidutswa" zambiri, zimatsitsa magwiridwe antchito; apa, zowonadi, malingaliro oyenera amafunikira.
Njirayi imalola olamulira kukonza zosungirako zotambasula ndi kusinthasintha kwakukulu. Mkati mwa dziwe la ARDFS, mutha kugwiritsa ntchito njira zololera zolakwika ndi kuphatikiza kwawo, zomwe, m'malingaliro athu, ndizothandiza kwambiri.
Pansipa pali tebulo lofanizira zingapo (zosatheka zonse) RF ndi EC ziwembu.
Gome limasonyeza kuti ngakhale kwambiri "terry" kuphatikiza EC 8 + 7, amene amalola imfa kwa 7 mfundo mu tsango imodzi, "amadya" zochepa ntchito danga (1,875 motsutsana 2) kuposa kugawanika muyezo, ndi kuteteza nthawi 7 bwino. , zomwe zimapangitsa kuti chitetezo ichi chitetezeke, ngakhale chovuta kwambiri, chokongola kwambiri panthawi yomwe kuli kofunikira kuonetsetsa kudalirika kwakukulu muzochitika za malo ochepa a disk. Panthawi imodzimodziyo, muyenera kumvetsetsa kuti "kuphatikiza" kulikonse kwa X kapena Y kudzakhala ntchito yowonjezera yowonjezera, kotero mu katatu pakati pa kudalirika, kusunga ndi ntchito muyenera kusankha mosamala kwambiri. Pachifukwa ichi, tipereka nkhani ina kuti tifufuze kukula kwa coding.
Kudalirika ndi kudziyimira pawokha kwamafayilo
ARDFS imayendetsa kwanuko pamagulu onse a gululo ndikuwagwirizanitsa pogwiritsa ntchito njira zawo kudzera m'malo odzipereka a Ethernet. Mfundo yofunika ndi yakuti ARDFS imagwirizanitsa paokha osati deta yokha, komanso metadata yokhudzana ndi kusungirako. Pamene tikugwira ntchito pa ARDFS, tinaphunzira nthawi imodzi njira zingapo zomwe zilipo ndipo tinapeza kuti ambiri amagwirizanitsa ma fayilo a meta pogwiritsa ntchito DBMS yogawidwa yakunja, yomwe timagwiritsanso ntchito kugwirizanitsa, koma makonzedwe okha, osati ma metadata a FS (za izi ndi ma subsystems ena). m'nkhani yotsatira).
Kulunzanitsa metadata ya FS pogwiritsa ntchito DBMS yakunja ndiyo njira yothetsera vutoli, koma kusasinthika kwa deta yosungidwa pa ARDFS kumadalira DBMS yakunja ndi khalidwe lake (ndipo, kunena zoona, ndi dona wosasamala), yemwe maganizo athu ndi oipa. Chifukwa chiyani? Ngati metadata ya FS iwonongeka, deta ya FS yokha inganenedwenso kuti "tasiya," choncho tinaganiza zotenga njira yovuta koma yodalirika.
Tidapanga kachipangizo kakang'ono ka metadata kwa ARDFS tokha, ndipo imakhala yosadalira magawo oyandikana nawo. Iwo. palibe dongosolo lina laling'ono lomwe lingawononge deta ya ARDFS. M'malingaliro athu, iyi ndiyo njira yodalirika komanso yolondola, koma nthawi idzawonetsa ngati izi zili choncho. Kuphatikiza apo, pali mwayi wowonjezera ndi njira iyi. ARDFS ingagwiritsidwe ntchito mopanda vAIR, monga momwe zimasungidwira, zomwe tidzagwiritsa ntchito pazinthu zamtsogolo.
Zotsatira zake, popanga ARDFS, talandira mafayilo osinthika komanso odalirika omwe amapereka chisankho komwe mungasungire mphamvu kapena kusiya chilichonse pakuchita, kapena kupanga zosungirako zodalirika kwambiri pamtengo wokwanira, koma kuchepetsa zofunikira zogwirira ntchito.
Pamodzi ndi lamulo losavuta lachilolezo komanso njira yosinthira yoperekera (kuyang'ana m'tsogolo, vAIR imaloledwa ndi node ndipo imaperekedwa ngati mapulogalamu kapena pulogalamu ya pulogalamu), izi zimapangitsa kuti zikhale zotheka kukonza molondola kwambiri njira yothetsera zosowa zosiyanasiyana za makasitomala ndi ndiye mosavuta kusunga izi moyenera.
Ndani akusowa chozizwitsa ichi?
Kumbali imodzi, titha kunena kuti pali osewera kale pamsika omwe ali ndi mayankho akulu pankhani ya hyperconvergence, ndipo apa ndipamene tikupita. Zikuwoneka kuti mawu awa ndi oona, KOMA ...
Kumbali ina, tikamapita kumunda ndikulankhula ndi makasitomala, ife ndi anzathu timawona kuti sizili choncho. Pali ntchito zambiri za hyperconvergence, m'malo ena anthu sankadziwa kuti njira zoterezi zilipo, zina zinkawoneka zodula, zina panali mayesero osapambana a njira zina zothetsera mavuto, ndipo ena amaletsa kugula chifukwa cha chilango. Nthawi zambiri, munda unakhala wosalimidwa, choncho tinapita kukakulitsa dothi lachikazi))).
Ndi liti pamene makina osungira ali abwino kuposa GCS?
Pamene tikugwira ntchito ndi msika, nthawi zambiri timafunsidwa kuti ndi liti pamene kuli bwino kugwiritsa ntchito chiwembu chapamwamba ndi machitidwe osungiramo zinthu, ndi nthawi yogwiritsira ntchito hyperconvergent? Makampani ambiri omwe amapanga GCS (makamaka omwe alibe makina osungira m'malo awo) amati: "Makina osungira ayamba kutha ntchito, akuphatikizana kwambiri!" Awa ndi mawu olimba mtima, koma samawonetsa zenizeni zenizeni.
Zoonadi, msika wosungirako ukupitadi ku hyperconvergence ndi mayankho ofanana, koma nthawi zonse pali "koma".
Choyamba, malo opangira ma data ndi zida za IT zomangidwa molingana ndi dongosolo lakale lokhala ndi makina osungira sizingamangidwenso mosavuta, kotero kukonzanso ndi kumalizidwa kwazinthu zotere ndi cholowa chazaka 5-7.
Kachiwiri, zomangamanga zomwe zikumangidwa nthawi zambiri (kutanthauza Russian Federation) zimamangidwa molingana ndi dongosolo lakale pogwiritsa ntchito machitidwe osungira, osati chifukwa chakuti anthu sadziwa za hyperconvergence, koma chifukwa msika wa hyperconvergence ndi watsopano, zothetsera ndi miyezo sinakhazikitsidwe , Anthu a IT sanaphunzitsidwebe, alibe chidziwitso chochepa, koma akufunika kumanga malo opangira deta pano ndi pano. Ndipo izi zikhala kwa zaka 3-5 (ndipo kenako cholowa china, onani mfundo 1).
Chachitatu, pali malire aukadaulo pakuchedwetsa pang'ono kwa 2 milliseconds polemba (kupatula cache yakomweko, inde), zomwe ndi mtengo wogawa zosungirako.
Chabwino, tisaiwale za kugwiritsa ntchito ma seva akuluakulu omwe amakonda kukweza molunjika kwa disk subsystem.
Pali ntchito zambiri zofunika komanso zodziwika pomwe makina osungira amakhala abwinoko kuposa GCS. Pano, ndithudi, opanga omwe alibe machitidwe osungiramo katundu wawo sangagwirizane nafe, koma ndife okonzeka kukangana momveka. Zachidziwikire, ife, monga opanga zinthu zonsezi, tidzafanizira njira zosungirako ndi GCS mu imodzi mwazofalitsa zathu zamtsogolo, pomwe tidzawonetsa bwino zomwe zili bwino pansi pamikhalidwe yotani.
Ndipo mayankho a hyperconverged angagwire ntchito bwino kuposa njira zosungirako?
Malingana ndi mfundo zomwe zili pamwambazi, mfundo zitatu zoonekeratu zikhoza kuganiziridwa:
- Pomwe ma 2 milliseconds owonjezera a latency pojambulira, omwe amapezeka nthawi zonse muzinthu zilizonse (tsopano sitikulankhula za zopangira, nanoseconds zitha kuwonetsedwa pakupanga), ndizosatsutsika, hyperconvergent ndiyoyenera.
- Kumene katundu wochokera ku maseva akuluakulu amatha kusinthidwa kukhala ang'onoang'ono ang'onoang'ono ndikugawidwa pakati pa ma node, hyperconvergence idzagwiranso ntchito bwino kumeneko.
- Kumene kukweza kopingasa kumakhala kofunikira kwambiri kuposa kukweza kowongoka, GCS idzachitanso bwino pamenepo.
Kodi mayankho awa ndi otani?
- Ntchito zonse zokhazikika zogwirira ntchito (ntchito zolembera, makalata, EDMS, ma seva a fayilo, machitidwe a ERP ang'onoang'ono kapena apakatikati ndi BI, etc.). Izi timazitcha "general computing".
- Zomangamanga za opereka mitambo, komwe kuli kofunikira kukulitsa mwachangu komanso mokhazikika mozungulira komanso "kudula" kuchuluka kwa makina enieni kwa makasitomala.
- Virtual desktop infrastructure (VDI), pomwe makina ang'onoang'ono ogwiritsira ntchito amayendetsa ndi "kuyandama" mwakachetechete mkati mwa gulu lofanana.
- Ma network a nthambi, pomwe nthambi iliyonse imafunikira njira yokhazikika, yololera zolakwika, koma yotsika mtengo ya makina pafupifupi 15-20.
- Makompyuta aliwonse ogawidwa (mwachitsanzo, ntchito zazikulu za data). Kumene katundu amapita osati "kuya", koma "m'lifupi".
- Malo oyesera omwe kuchedwa kwina kwina kuli kovomerezeka, koma pali zoletsa za bajeti, chifukwa awa ndi mayeso.
Pakalipano, ndi ntchito izi zomwe tapanga AERODISK vAIR ndipo ndizomwe tikuyang'ana (zopambana mpaka pano). Mwina izi zisintha posachedwa, chifukwa ... dziko siliima nji.
Ndiyeβ¦
Izi zimamaliza gawo loyamba la mndandanda waukulu wa nkhani; m'nkhani yotsatira tidzakambirana za kamangidwe ka yankho ndi zigawo zomwe zimagwiritsidwa ntchito.
Timalandila mafunso, malingaliro ndi mikangano yolimbikitsa.
