Musanganiswa uyu unobvumidza iwe kuita akawanda ekuchengetedza sisitimu maficha padanho rekuona uye zvese kubva kune rimwe hwindo rekutonga.
Mukambani yedu, mapurojekiti ekugadzira akadhindwa data nzvimbo ari kudiwa zvakanyanya, uye hyperconverged mhinduro inowanzosarudzwa nekuda kweboka rezvisarudzo zvekudzokorora (kusvika kune metrocluster) kunze kwebhokisi.
Kana iri nzvimbo yekuchengetedza data, isu tinowanzo kutaura nezve nzvimbo iri kure pane saiti kune rumwe rutivi rweguta kana mune rimwe guta zvachose. Inokubvumira kuti udzorere masisitimu akakosha muchiitiko chekutadza kwechikamu kana kuzere kweiyo main data center. Dhata rekutengesa rinogara richidzokororwa ipapo, uye kudzokorora uku kunogona kunge kuri padanho rekushandisa kana padanho rekuvhara mudziyo (yekuchengetedza).
Naizvozvo, ikozvino ini ndichataura nezve sisitimu dhizaini uye bvunzo, uyezve nezve akati wandei-chaiwo ehupenyu maapplication mamiriro ane data rekuchengetedza.
Miedzo
Muenzaniso wedu une maseva mana, imwe neimwe ine gumi SSD madhiraivha e10 GB. Kune dhisiki yakatsaurirwa ye caching kunyora mashandiro uye kuchengetedza sevhisi chaiyo muchina. Mhinduro yacho pachayo ishanduro yechina. Yekutanga haina kuchena (tichitonga neongororo), yechipiri yakanyorova, yechitatu yatove yakagadzikana, uye iyi inogona kunzi kuburitswa mushure mekupera kwekuyedza beta kune veruzhinji. Panguva yekuyedzwa handina kuona matambudziko, zvese zvinoshanda sewachi.
Shanduko muv4Boka rezvipembenene zvakagadziriswa.
Pakutanga, chikuva chaigona chete kushanda neVMware ESXi hypervisor uye yakatsigira nhamba shoma yemanode. Zvakare, nzira yekuendesa haina kupera nguva dzose zvinobudirira, mamwe matanho aifanira kutangwazve, pakanga paine matambudziko nekuvandudzwa kubva kushanduro dzekare, data muGUI haina kugara ichiratidzwa nenzira kwayo (kunyangwe ini ndichiri kusafara nekuratidzwa kwekuita magirafu. ), dzimwe nguva matambudziko akamuka pakusangana ne virtualization.
Iye zvino matambudziko ese ehuduku akagadziriswa, HyperFlex inogona kubata ese ESXi neHyper-V, uyezve zvinokwanisika ku:
- Kugadzira sumbu rakatambanudzwa.
- Kugadzira sumbu remahofisi pasina kushandisa Fabric Interconnect, kubva maviri kusvika mana node (tinotenga maseva chete).
- Kugona kushanda nekunze kwekuchengetedza masisitimu.
- Tsigiro yemidziyo uye Kubernetes.
- Kugadzirwa kwenzvimbo dzinowanikwa.
- Kubatanidzwa neVMware SRM kana iyo yakavakirwa-mukati mashandiro isiri kugutsa.
Iyo dhizaini haina kunyanya kusiyana nemhinduro dzevakwikwidzi vayo vakuru; ivo havana kugadzira bhasikoro. Izvo zvese zvinomhanya paVMware kana Hyper-V virtualization chikuva. Iyo hardware inotambirwa pavaridzi veCisco UCS maseva. Kune avo vanovenga chikuva chehukama hwakaoma hwekutanga setup, akawanda mabhatani, isiri-yadiki sisitimu yematemplate uye kutsamira, asi kune zvakare avo vakadzidza Zen, vanofemerwa nepfungwa uye havachada. kushanda nemamwe maseva.
Isu tichafunga nezve mhinduro yeVMware, sezvo mhinduro yacho yakatanga kusikirwa uye ine zvimwe mashandiro; Hyper-V yakawedzerwa munzira kuitira kuti ienderane nevakwikwidzi uye kusangana nezvinotarisirwa pamusika.
Pane boka remaseva akazara nemadhisiki. Kune madhisiki ekuchengetedza data (SSD kana HDD - zvinoenderana nekuravira kwako uye zvaunoda), kune imwe SSD dhisiki ye caching. Paunenge uchinyora data kuchitoro chedata, iyo data inochengetwa pane caching layer (yakatsaurirwa SSD disk uye RAM yebasa VM). Mukufanana, bhuroka re data rinotumirwa kune node musumbu (nhamba yemanodhi zvinoenderana neiyo cluster replication factor). Mushure mekusimbiswa kubva kune ese node nezve yakabudirira kurekodha, simbiso yekurekodha inotumirwa kune hypervisor uyezve kuVM. Iyo data yakarekodhwa inobviswa, yakatsikirirwa uye inonyorerwa kumadhisiki ekuchengetedza kumashure. Panguva imwecheteyo, chivharo chikuru chinogara chichinyorwa kune dhisiki dzekuchengetedza uye sequentially, izvo zvinoderedza mutoro pamadhisiki ekuchengetedza.
Deduplication uye compression zvinogara zvichigoneswa uye hazvigone kudzimwa. Dhata inoverengwa zvakananga kubva kumadhisiki ekuchengetedza kana kubva ku RAM cache. Kana iyo yakasanganiswa kumisikidzwa ikashandiswa, iyo kuverenga inochengeterwawo paSSD.
Iyo data haina kusungirirwa kune yazvino nzvimbo yemuchina chaiwo uye inogoverwa zvakaenzana pakati pemanodhi. Iyi nzira inobvumidza iwe kurodha ese madhisiki uye network network zvakaenzana. Pane kukanganisa kuri pachena: isu hatigone kuderedza kuverenga latency zvakanyanya sezvinobvira, sezvo pasina vimbiso yekuwanikwa kwedata munharaunda. Asi ndinotenda kuti ichi chibayiro chiduku kana chichienzaniswa nemakomborero anowanikwa. Zvakare, kunonoka kwenetiweki kwasvika hunhu hwakadaro zvekuti hahuna kukanganisa mhedzisiro yacho.
Iyo yakakosha sevhisi VM Cisco HyperFlex Data Platform controller, iyo inogadzirwa pane imwe neimwe yekuchengetedza node, ine basa rekuita kwese mashandiro eiyo disk subsystem.
