Iyi ndi nthano yomwe ili yofala kwambiri pamasewera a seva. M'malo mwake, mayankho a hyperconverged (pamene chilichonse chili m'modzi) amafunikira pazinthu zambiri. Zakale, zomanga zoyamba zidapangidwa ndi Amazon ndi Google chifukwa cha ntchito zawo. Ndiye lingaliro linali lopanga famu yamakompyuta kuchokera ku mfundo zofanana, iliyonse yomwe inali ndi ma disks ake. Zonsezi zidalumikizidwa ndi mapulogalamu ena opanga makina (hypervisor) ndipo adagawidwa kukhala makina enieni. Cholinga chachikulu ndikuyesa kocheperako pakutumikira node imodzi ndi zovuta zochepa pakukulitsa: ingogulani ma seva ena chikwi chimodzi kapena ziwiri ndikulumikiza pafupi. M'malo mwake, awa ndi milandu yokhayokha, ndipo nthawi zambiri timalankhula za nambala yaying'ono komanso zomangamanga zosiyana.
Koma kuphatikiza kumakhalabe komweko - kumasuka kodabwitsa kwa makulitsidwe ndi kasamalidwe. Choyipa chake ndi chakuti ntchito zosiyanasiyana zimadya zinthu mosiyanasiyana, ndipo m'malo ena padzakhala ma disks am'deralo, ena padzakhala RAM pang'ono, ndi zina zotero, ndiko kuti, pamitundu yosiyanasiyana ya ntchito, kugwiritsa ntchito zinthu kudzachepa.
Zikuoneka kuti mumalipira 10-15% yowonjezerapo kuti muchepetse khwekhwe. Izi ndi zomwe zidayambitsa nthano pamutuwu. Tinakhala nthawi yayitali kufunafuna komwe ukadaulo ungagwiritsiridwe ntchito bwino, ndipo tidaupeza. Chowonadi ndi chakuti Cisco inalibe makina ake osungira, koma ankafuna msika wathunthu wa seva. Ndipo adapanga Cisco Hyperflex - yankho lokhala ndi malo osungirako pamfundo.
Ndipo izi mwadzidzidzi zidakhala njira yabwino kwambiri yosungira zosunga zobwezeretsera (Kubwezeretsa Masoka). Ndikuuzani chifukwa chake komanso bwanji tsopano. Ndipo ndikuwonetsani mayeso a magulu.
Pamene pakufunika
Hyperconvergence ndi:
- Kusamutsa ma disks ku ma node owerengera.
- Kuphatikizika kwathunthu kwa kagawo kakang'ono kosungirako ndi kagawo kakang'ono ka virtualization.
- Kusamutsa/kuphatikiza ndi netiweki subsystem.
Kuphatikiza uku kumakupatsani mwayi wogwiritsa ntchito zida zambiri zosungira pamlingo wa virtualization ndi zonse kuchokera pawindo limodzi lowongolera.
Pakampani yathu, mapulojekiti opangira ma data osafunikira akufunika kwambiri, ndipo yankho la hyperconverged nthawi zambiri limasankhidwa chifukwa cha zosankha zingapo zobwereza (mpaka metrocluster) kuchokera m'bokosi.
Pankhani ya malo osungirako deta, nthawi zambiri tikukamba za malo akutali pa malo kumbali ina ya mzindawo kapena mumzinda wina palimodzi. Zimakupatsani mwayi wobwezeretsa machitidwe ovuta pakagwa pang'ono kapena kulephera kwathunthu kwa data center. Deta yogulitsa imabwerezedwa nthawi zonse pamenepo, ndipo kubwereza uku kumatha kukhala pamlingo wogwiritsa ntchito kapena pamlingo wa block chipangizo (chosungira).
Chifukwa chake, tsopano ndilankhula za kapangidwe ka makina ndi mayeso, ndiyeno za zochitika zingapo zenizeni zenizeni zokhala ndi deta yosungira.
Mayesero
Chitsanzo chathu chimakhala ndi ma seva anayi, omwe ali ndi ma drive 10 SSD a 960 GB. Pali diski yodzipatulira yosungiramo ntchito zolembera ndikusunga makina ogwiritsira ntchito. Yankho lokha ndilo lachinayi. Yoyamba ndiyopanda pake (kutengera ndemanga), yachiwiri ndi yonyowa, yachitatu ndi yokhazikika, ndipo iyi ikhoza kutchedwa kumasulidwa pambuyo pomaliza kuyesa kwa beta kwa anthu wamba. Pakuyesa sindinawone vuto lililonse, chilichonse chimagwira ntchito ngati wotchi.
Kusintha kwa v4Mulu wa nsikidzi zakonzedwa.
Poyambirira, nsanjayo imatha kugwira ntchito ndi VMware ESXi hypervisor ndikuthandizira ma node ochepa. Komanso, ndondomeko yotumizira siinathe nthawi zonse bwino, masitepe ena amayenera kuyambiranso, panali mavuto ndi kukonzanso kuchokera ku matembenuzidwe akale, deta mu GUI sinasonyezedwe molondola (ngakhale sindiri wokondwa ndi mawonedwe a ma grafu ogwira ntchito. ), nthawi zina pamakhala mavuto pamawonekedwe ndi virtualization.
Tsopano mavuto onse aubwana akhazikitsidwa, HyperFlex imatha kuthana ndi ESXi ndi Hyper-V, kuphatikiza ndizotheka:
- Kupanga gulu lotambasulidwa.
- Kupanga gulu la maofesi popanda kugwiritsa ntchito Fabric Interconnect, kuchokera ku mfundo ziwiri mpaka zinayi (timagula ma seva okha).
- Kutha kugwira ntchito ndi machitidwe osungira kunja.
- Kuthandizira zotengera ndi Kubernetes.
- Kupanga madera opezeka.
- Kuphatikiza ndi VMware SRM ngati magwiridwe antchito sali okhutiritsa.
Zomangamanga sizosiyana kwambiri ndi mayankho a omwe akupikisana nawo; sanapange njinga. Zonse zimayenda pa VMware kapena Hyper-V virtualization platform. Zipangizozi zimakhala ndi ma seva a Cisco UCS. Pali anthu omwe amadana ndi nsanja chifukwa cha zovuta za kukhazikitsidwa koyambirira, mabatani ambiri, dongosolo losachepera la ma templates ndi kudalira, koma palinso omwe aphunzira Zen, amalimbikitsidwa ndi lingaliro ndipo sakufunanso. kugwira ntchito ndi ma seva ena.
Tikambirana yankho la VMware, popeza yankho lidapangidwa poyambirira ndipo lili ndi magwiridwe antchito ambiri; Hyper-V idawonjezedwa panjira kuti igwirizane ndi omwe akupikisana nawo ndikukwaniritsa zomwe msika ukuyembekezeka.
Pali gulu la ma seva odzaza ndi ma disks. Pali ma disks osungira deta (SSD kapena HDD - malinga ndi kukoma kwanu ndi zosowa zanu), pali disk imodzi ya SSD yosungirako. Mukalemba deta kumalo osungirako deta, deta imasungidwa pa caching layer (yodzipereka SSD disk ndi RAM ya utumiki VM). Mofananamo, chipika cha data chimatumizidwa ku node mu masango (chiwerengero cha node chimadalira chigawo chobwerezabwereza). Pambuyo potsimikizira kuchokera ku node zonse za kujambula bwino, chitsimikiziro cha kujambula chimatumizidwa kwa hypervisor ndiyeno ku VM. Deta yojambulidwa imachotsedwa, kukakamizidwa ndikulembedwa kuma disks osungira kumbuyo. Panthawi imodzimodziyo, chipika chachikulu chimalembedwa nthawi zonse ku ma disks osungiramo ndi sequentially, zomwe zimachepetsa katundu pa disks yosungirako.
Kuchotsa ndi kukanikiza kumayatsidwa nthawi zonse ndipo sikungalephereke. Deta imawerengedwa mwachindunji kuchokera ku ma disks osungira kapena kuchokera ku RAM cache. Ngati kasinthidwe wosakanizidwa agwiritsidwa ntchito, zowerengera zimasungidwanso pa SSD.
Detayo siimangirizidwa ku malo omwe alipo panopa makina enieni ndipo imagawidwa mofanana pakati pa mfundo. Njira iyi imakupatsani mwayi wotsitsa ma disks onse ndi ma network olumikizirana mofanana. Pali zovuta zoonekeratu: sitingathe kuchepetsa kuwerenga latency momwe tingathere, popeza palibe chitsimikizo cha kupezeka kwa deta kwanuko. Koma ndimakhulupirira kuti imeneyi ndi nsembe yaing’ono poiyerekezera ndi mapindu amene timalandira. Kuphatikiza apo, kuchedwa kwa ma netiweki kwafika pamiyezo kotero kuti sikukhudza zotsatira zonse.
Utumiki wapadera wa VM Cisco HyperFlex Data Platform controller, yomwe imapangidwa pa malo aliwonse osungira, imayang'anira ndondomeko yonse ya disk subsystem. Mu kasinthidwe ka VM yathu yautumiki, ma vCPU asanu ndi atatu ndi 72 GB ya RAM adagawidwa, omwe si ochepa kwambiri. Ndiroleni ndikukumbutseni kuti mwiniwakeyo ali ndi ma cores 28 ndi 512 GB ya RAM.
VM yautumiki imatha kupeza ma disks akuthupi mwachindunji potumiza wolamulira wa SAS ku VM. Kuyankhulana ndi hypervisor kumachitika kudzera mu gawo lapadera la IOVisor, lomwe limasokoneza ntchito za I / O, ndikugwiritsa ntchito wothandizira omwe amakulolani kutumiza malamulo ku hypervisor API. Wothandizira ali ndi udindo wogwira ntchito ndi HyperFlex snapshots ndi ma clones.
Zida za Disk zimayikidwa mu hypervisor monga magawo a NFS kapena SMB (malingana ndi mtundu wa hypervisor, ganizirani kuti ndi ndani). Ndipo pansi pa hood, iyi ndi fayilo yogawidwa yomwe imakulolani kuti muwonjezere machitidwe a anthu akuluakulu osungira zinthu zonse: kugawanika kwa voliyumu yopyapyala, kuponderezana ndi kuchotseratu, zithunzithunzi pogwiritsa ntchito teknoloji ya Redirect-on-Write, synchronous / asynchronous replication.
Utumiki wa VM umapereka mwayi wopezera mawonekedwe a WEB kasamalidwe ka HyperFlex subsystem. Pali kuphatikiza ndi vCenter, ndipo ntchito zambiri zatsiku ndi tsiku zitha kuchitidwa kuchokera pamenepo, koma malo osungiramo zinthu, mwachitsanzo, ndiosavuta kudula kuchokera pawebusayiti yosiyana ngati mwasinthira kale mawonekedwe a HTML5 othamanga, kapena kugwiritsa ntchito Flash kasitomala wathunthu. ndi kuphatikiza kwathunthu. Mu webcam yautumiki mutha kuwona momwe zimagwirira ntchito komanso tsatanetsatane wadongosolo.
Palinso mtundu wina wa node mu cluster - computing node. Izi zitha kukhala ma rack kapena ma seva opanda ma disks omangidwa. Ma seva awa amatha kuyendetsa ma VM omwe deta yawo imasungidwa pa maseva okhala ndi ma disks. Kuchokera pakuwona kwa deta, palibe kusiyana pakati pa mitundu ya node, chifukwa zomangamanga zimaphatikizapo kuchotseratu malo enieni a deta. Chiŵerengero chachikulu cha ma node apakompyuta ndi malo osungira ndi 2: 1.
Kugwiritsa ntchito ma compute node kumawonjezera kusinthasintha pakukulitsa zida zamagulu: sitiyenera kugula ma node owonjezera okhala ndi ma disk ngati tikufuna CPU / RAM. Kuphatikiza apo, titha kuwonjezera khola lamasamba ndikusunga pamayikidwe oyika ma seva.
Zotsatira zake, tili ndi nsanja ya hyperconverged yokhala ndi izi:
- Kufikira ma node 64 pagulu (mpaka ma node 32 osungira).
- Chiwerengero chocheperako cha node pagulu ndi atatu (awiri a gulu la Edge).
- Dongosolo la redundancy la data: kuwonetsera ndi replication factor 2 ndi 3.
- Gulu la Metro.
- Kubwereza kwa Asynchronous VM ku gulu lina la HyperFlex.
