Le yintsomi eqhelekileyo kwintsimi yehardware yomncedisi. Enyanisweni, izisombululo ze-hyperconverged (xa yonke into inye) iyadingeka kwizinto ezininzi. Ngokomlando, izakhiwo zokuqala zaphuhliswa yi-Amazon kunye neGoogle ngeenkonzo zabo. Emva koko ingcamango yayikukwenza ifama yekhompyutha ukusuka kwiindawo ezifanayo, nganye kuzo yayineediski zayo. Konke oku kwadityaniswa yinkqubo ethile yokwenza inkqubo (hypervisor) kwaye yahlulwa yaba ngoomatshini ababonakalayo. Injongo ephambili yincinci yomgudu wokusevisa i-node enye kunye nobuncinci beengxaki xa ulinganisa: vele uthenge elinye iwaka okanye ezimbini zeeseva ezifanayo kwaye udibanise kufuphi. Enyanisweni, ezi ziimeko ezizimeleyo, kwaye kaninzi sithetha ngamanani amancinci kunye nolwakhiwo olwahlukileyo.
Kodwa i-plus ihlala ifana-ukulula okumangalisayo kokulinganisa kunye nokulawula. I-downside kukuba imisebenzi eyahlukeneyo idla izibonelelo ngokwahlukileyo, kwaye kwezinye iindawo kuya kuba neediski ezininzi zendawo, kwezinye kuya kuba ne-RAM encinci, kunye nokunye, oko kukuthi, kwiintlobo ezahlukeneyo zemisebenzi, ukusetyenziswa kwezixhobo kuya kuncipha.
Kuyavela ukuba uhlawula i-10-15% ngaphezulu ukuze kube lula ukuseta. Yiloo nto eyabangela intsomi kwisihloko. Sichithe ixesha elide sikhangela apho ubuchwephesha buya kusetyenziswa ngokugqibeleleyo, kwaye sabufumana. Inyani kukuba iCisco yayingenazo iinkqubo zayo zokugcina, kodwa babefuna imarike yeseva epheleleyo. Kwaye benza iCisco Hyperflex - isisombululo kunye nokugcinwa kwendawo kwiindawo.
Kwaye oku ngequbuliso kwajika kwaba sisisombululo esihle kakhulu kumaziko ogcino lwedatha (UkuBuyiselwa kweNtlekele). Ndiza kukuxelela ukuba kutheni kwaye njani ngoku. Kwaye ndiza kukubonisa iimvavanyo zeqela.
Apho kufuneka khona
I-Hyperconvergence yile:
- Ukutshintshela iidiski ukubala iinodi.
- Ukudityaniswa okupheleleyo kwenkqubo engaphantsi kogcino kunye nenkqubo engaphantsi kwe-virtualization.
- Ugqithiso/udibaniso kunye nenkqubo engaphantsi yothungelwano.
Le ndibaniselwano ikuvumela ukuba uphumeze uninzi lweempawu zenkqubo yogcino kwinqanaba le-virtualization kwaye zonke zivela kwifestile enye yolawulo.
Kwinkampani yethu, iiprojekthi zokuyila amaziko edatha angafunekiyo zifunwa kakhulu, kwaye isisombululo se-hyperconverged sihlala sikhethwa ngenxa yeqela leendlela zokuphindaphinda (ukuya kwi-metrocluster) ngaphandle kwebhokisi.
Kwimeko yamaziko edatha yogcino, sihlala sithetha malunga nesibonelelo esikude kwisiza kwelinye icala lesixeko okanye kwesinye isixeko ngokupheleleyo. Ikuvumela ukuba ubuyisele iinkqubo ezibalulekileyo xa kwenzeka ukungaphumeleli inxalenye okanye epheleleyo yeziko ledatha eliphambili. Idatha yokuthengisa ihlala iphinda iphindwe apho, kwaye oku kuphindaphinda kunokuba kwinqanaba lesicelo okanye kwisixhobo sebhloko (ukugcinwa) kwinqanaba.
Ke ngoko, ngoku ndiza kuthetha ngoyilo lwenkqubo kunye neemvavanyo, kwaye emva koko malunga neemeko ezimbalwa zobomi bokwenyani besicelo kunye nedatha yokonga.
Iimvavanyo
Umzekelo wethu uqukethe iiseva ezine, nganye ine-10 SSD drives ye-960 GB. Kukho idiski enikezelweyo ye-caching yokubhala imisebenzi kunye nokugcina umatshini wenkonzo yenyani. Isisombululo ngokwaso yinguqulelo yesine. Eyokuqala ikrwada ngokungafihlisiyo (ukugweba ngophononongo), eyesibini ifumile, eyesithathu sele izinzile, kwaye le ingabizwa ngokuba kukukhululwa emva kokuphela kovavanyo lwe-beta kuluntu ngokubanzi. Ngexesha lokuvavanya andizange ndibone naziphi na iingxaki, yonke into isebenza njengewashi.
Utshintsho kwi-v4Iqela leempazamo lilungisiwe.
Ekuqaleni, iqonga lingasebenza kuphela kunye ne-VMware ESXi hypervisor kwaye ixhase inani elincinci leendawo. Kwakhona, inkqubo yokuthunyelwa ayizange ihlale iphela ngempumelelo, amanye amanyathelo kwafuneka aqaliswe kwakhona, kwakukho iingxaki ngohlaziyo olusuka kwiinguqulelo ezindala, idatha kwi-GUI yayingasoloko iboniswa ngokuchanekileyo (nangona ndingonwabanga kukuboniswa kweegrafu zokusebenza. ), ngamanye amaxesha kwavela iingxaki kwi-interface ene-virtualization .
Ngoku zonke iingxaki zobuntwana zilungisiwe, i-HyperFlex inokusingatha zombini i-ESXi kunye ne-Hyper-V, kwaye kunokwenzeka ukuba:
- Ukudala iqoqo eloluliweyo.
- Ukudala i-cluster yeeofisi ngaphandle kokusebenzisa i-Fabric Interconnect, ukusuka kwiindawo ezimbini ukuya kwezine (sithenga kuphela iiseva).
- Ukukwazi ukusebenza kunye neenkqubo zokugcina zangaphandle.
- Inkxaso yezikhongozeli kunye neKubernetes.
- Ukudalwa kweendawo ezifumanekayo.
- Ukudityaniswa ne-VMware SRM ukuba umsebenzi owakhelwe ngaphakathi awanelisi.
Uyilo aluhlukanga kakhulu kwizisombululo zabo bakhuphisana nabo abaphambili; abazange benze ibhayisekile. Konke kuqhuba kwiqonga le-VMware okanye le-Hyper-V. I-hardware ibanjwe kwiiseva ze-Cisco UCS zobunikazi. Kukho abo bayithiyileyo iqonga lobunzima bokucwangciswa kokuqala, amaqhosha amaninzi, inkqubo engeyiyo encinci yeetemplates kunye nokuxhomekeka, kodwa kukho nabo bafunde iZen, baphefumlelwe ngumbono kwaye abasafuni. ukusebenza nabanye abancedisi.
Siza kuqwalasela isisombululo se-VMware, ekubeni isisombululo sasidalelwe sona kwaye sinomsebenzi ongaphezulu; I-Hyper-V yongezwa endleleni ukuze uhambisane nabakhuphisana kunye nokuhlangabezana nokulindela kwimarike.
Kukho iqela labancedisi abagcwele iidiski. Kukho iidiski zokugcina idatha (i-SSD okanye i-HDD - ngokuhambelana nencasa yakho kunye neemfuno), kukho idiski enye ye-SSD ye-caching. Xa ubhala idatha kwi-datastore, idatha igcinwa kwi-caching layer (i-SSD disk ezinikeleyo kunye ne-RAM yenkonzo ye-VM). Ngokuhambelanayo, ibhloko yedatha ithunyelwa kwiinqununu kwi-cluster (inani leenqununu lixhomekeke kwi-cluster replication factor). Emva kokuqinisekiswa kuzo zonke iindawo malunga nokurekhoda okuyimpumelelo, ukuqinisekiswa kokurekhoda kuthunyelwa kwi-hypervisor kwaye emva koko kwi-VM. Idatha erekhodiweyo ikhutshwe, ixinzelelwe kwaye ibhalwe kwiidiski zokugcina ngasemva. Ngexesha elifanayo, ibhloko enkulu ihlala ibhaliwe kwiidiski zokugcina kunye nokulandelelana, okunciphisa umthwalo kwiidiski zokugcina.
Ukunciphisa kunye noxinzelelo luhlala lusebenza kwaye alunakukhutshazwa. Idatha ifundwa ngokuthe ngqo kwiidiski zokugcina okanye kwi-cache ye-RAM. Ukuba ulungelelwaniso lwe-hybrid lusetyenzisiwe, ukufundwa kwakhona kugcinwe kwi-SSD.
Idatha ayibophelwanga kwindawo yangoku yomatshini wenyani kwaye isasazwa ngokulinganayo phakathi kweenodi. Le ndlela ikuvumela ukuba ulayishe zonke iidiski kunye nojongano lwenethiwekhi ngokulinganayo. Kukho ukungonakali okucacileyo: asikwazi ukunciphisa i-latency yokufunda kangangoko, kuba akukho siqinisekiso sokufumaneka kwedatha kwindawo. Kodwa ndikholelwa ukuba eli lidini elincinane xa lithelekiswa neengenelo endizifumeneyo. Ngapha koko, ukulibaziseka kwenethiwekhi kuye kwafikelela kumaxabiso anjalo kangangokuba azichaphazeli iziphumo zizonke.
Inkonzo ekhethekileyo ye-VM Cisco HyperFlex Data Platform isilawuli, esidalwe kwi-node nganye yokugcina, ijongene nayo yonke ingqiqo yokusebenza kwe-disk subsystem. Kwinkonzo yethu yokucwangciswa kwe-VM, ii-vCPU ezisibhozo kunye ne-72 GB ye-RAM zabelwe, ezingekho ncinane kakhulu. Makhe ndikukhumbuze ukuba umphathi ngokwawo unama-cores angama-28 kunye ne-512 GB ye-RAM.
Inkonzo ye-VM inokufikelela kwiidiski eziphathekayo ngokuthe ngqo ngokuthumela umlawuli we-SAS kwi-VM. Unxibelelwano kunye ne-hypervisor lwenzeka ngemodyuli ekhethekileyo ye-IOVisor, ebamba imisebenzi ye-I / O, kunye nokusebenzisa i-arhente evumela ukuba uthumele imiyalelo kwi-hypervisor API. I-arhente inoxanduva lokusebenza kunye ne-HyperFlex snapshots kunye neeclones.
Izixhobo zeDiski zifakwe kwi-hypervisor njenge-NFS okanye izabelo ze-SMB (kuxhomekeke kuhlobo lwe-hypervisor, qikelela ukuba yeyiphi apho). Kwaye phantsi kwe-hood, le yinkqubo yefayile esasazwayo evumela ukuba ungeze iimpawu zeenkqubo zokugcina ezipheleleyo zabantu abadala: ulwabiwo lwevolumu encinci, ukunyanzeliswa kunye nokunciphisa, i-snapshots usebenzisa i-Redirect-on-Write technology, i-synchronous / asynchronous replication.
Inkonzo ye-VM ibonelela ngokufikelela kwi-WEB management interface ye-HyperFlex subsystem. Kukho udibaniso kunye ne-vCenter, kwaye uninzi lwemisebenzi yemihla ngemihla inokwenziwa kuyo, kodwa iivenkile zokugcina idatha, umzekelo, zikulungele ngakumbi ukusika kwikhamera yewebhu eyahlukileyo ukuba sele utshintshele kwi-interface ye-HTML5 ekhawulezayo, okanye usebenzise iFlash client epheleleyo. ngokudibanisa ngokupheleleyo. Kwikhamera yewebhu yenkonzo unokujonga ukusebenza kunye nobume obucacileyo benkqubo.
Kukho olunye uhlobo lweenodi kwiqela le-computing nodes. Ezi zinokuba yi-rack okanye iiseva ze-blade ngaphandle kweediski ezakhelwe ngaphakathi. Ezi seva zinokusebenzisa ii-VM ezidatha yazo igcinwe kwiiseva ezinediski. Ukusuka kwindawo yokujonga ukufikelela kwedatha, akukho mahluko phakathi kweentlobo ze-nodes, kuba i-architecture ibandakanya ukuchithwa kwindawo ebonakalayo yedatha. Umlinganiselo ophezulu weendawo zekhompyutha ukuya kwiindawo zokugcina yi-2: 1.
Ukusebenzisa i-compute nodes kwandisa ukuguquguquka xa ulinganisa izixhobo ze-cluster: akufuneki sithenge ii-nodes ezongezelelweyo ngeediski ukuba sifuna kuphela i-CPU / RAM. Ukongeza, singongeza ikheji yeblade kwaye sigcine kwindawo yokubeka iiseva.
Ngenxa yoko, sineqonga le-hyperconverged elinezi mpawu zilandelayo:
- Ukuya kuthi ga kwi-64 nodes kwi-cluster (ukuya kwii-nodes ze-32 zokugcina).
- Ubuncinci benani leendibano kwiqela zintathu (ezimbini zeqela le-Edge).
- Indlela yokuphindaphinda idatha: isipili nge-replication factor 2 kunye ne-3.
- Iqela leMetro.
- Ukuphindaphinda kwe-VM ye-Asynchronous kwelinye iqela le-HyperFlex.
- I-orchestration yokutshintsha ii-VM kwiziko ledatha elikude.
- Izifinyezo zomthonyama kusetyenziswa itekhnoloji yokuqondisa ngokutsha-kwi-Bhala.
- Ukuya kuthi ga kwi-1 PB yendawo esebenzisekayo kwi-replication factor 3 kwaye ngaphandle kokudityaniswa. Asiyi kuqwalasela i-replication factor 2, kuba oku akusiyo inketho yokuthengisa okunzulu.
Enye into enkulu kukuphatha ngokulula kunye nokusasazwa. Zonke izinto ezintsonkothileyo zokuseta iiseva ze-UCS zikhathalelwa yi-VM ekhethekileyo elungiselelwe ziinjineli zeCisco.

I-Bold ibonisa amaxabiso emva koko kungabikho ukwanda kwimveliso, ngamanye amaxesha ukuthotywa kuyabonakala. Oku kubangelwa ukuba silinganiselwe ngokusebenza kwenethiwekhi / abalawuli / iidisks.
- Ulandelelwano lufundeka 4432 MB/s.
- Ulandelelwano bhala 804 MB/s.
- Ukuba umlawuli omnye uyasilela (ukusilela komatshini wenyani okanye umphathi), ukuhla kokusebenza kuphindwe kabini.
- Ukuba idiski yokugcina ayiphumelelanga, i-drawdown yi-1/3. Ukwakhiwa kwakhona kweDiski kuthatha i-5% yezibonelelo zomlawuli ngamnye.
Kwibhloko encinci, sinqunyelwe ngokusebenza komlawuli (umatshini obonakalayo), i-CPU yayo ilayishwe kwi-100%, kwaye xa ibhloko yanda, sinqunyelwe yi-bandwidth ye-port. I-10 Gbps ayonelanga ukuvula amandla enkqubo ye-AllFlash. Ngelishwa, iiparamitha zedemo enikezelweyo ayivumeli ukuba sivavanye ukusebenza kwi-40 Gbit / s.
Kwimbonakaliso yam evela kwiimvavanyo kunye nokufunda i-architecture, ngenxa ye-algorithm ebeka idatha phakathi kwayo yonke imikhosi, sifumana i-scalable, intsebenzo eqikelelwayo, kodwa oku kwakhona kukuthintelwa xa kufundwa, kuba kuya kuba nokwenzeka ukucudisa ngakumbi kwiidiski zendawo, apha inokugcina inethiwekhi enemveliso ngakumbi, umzekelo, i-FI kwi-40 Gbit/s iyafumaneka.
Kwakhona, idiski enye ye-caching kunye nokunciphisa inokuba ngumda; enyanisweni, kule testbed sinokubhalela kwiidiski ezine ze-SSD. Kuya kuba kuhle ukukwazi ukwandisa inani le-caching drives kwaye ubone umahluko.
Ukusetyenziswa kwangempela
Ukuququzelela iziko ledatha yogcino, ungasebenzisa iindlela ezimbini (asicingi ngokubeka ugcino kwindawo ekude):
- Esebenzayo-Yenziwa. Zonke izicelo zibanjwe kwiziko ledatha eliphambili. Uphindaphindo lungqamaniso okanye alulungelelanisiyo. Ukuba iziko ledatha eliphambili liyasilela, kufuneka sivule i-backup. Oku kunokwenziwa ngesandla/iscripts/ochestration izicelo. Apha siya kufumana i-RPO ehambelana nokuphindaphinda, kwaye i-RTO ixhomekeke kwimpendulo kunye nezakhono zomlawuli kunye nomgangatho wophuhliso / ukulungiswa kwesicwangciso sokutshintsha.
- Iyasebenza-Esebenzayo. Kule meko, kukho ukuphindaphinda okuhambelanayo kuphela; ukufumaneka kwamaziko edatha kugqitywa yi-quorum / i-arbiter ebekwe ngokungqongqo kwindawo yesithathu. I-RPO = 0, kunye ne-RTO inokufikelela kwi-0 (ukuba isicelo sivumela) okanye ilingana nexesha le-failover ye-node kwi-cluster virtualization. Kwinqanaba le-virtualization, iqoqo eloluliweyo (iMetro) lenziwe elifuna i-Active-Active storage.
Ngokuqhelekileyo sibona ukuba abathengi sele bephumeze i-architecture kunye nenkqubo yokugcina i-classic kwiziko ledatha eliphambili, ngoko ke siyila enye ukuphindaphinda. Njengoko benditshilo, iCisco HyperFlex ibonelela ngokuphindaphindwa kwe-asynchronous kunye nokudalwa kweqela le-virtualization. Kwangaxeshanye, asiyidingi inkqubo yokugcina ezinikeleyo yomgangatho weMidrange kwaye iphezulu kunye nemisebenzi ebiza imali eninzi yokuphindaphinda kunye nokufikelela kwedatha ye-Active-Active kwiinkqubo ezimbini zokugcina.
Imeko 1: Sinamaziko edatha asisiseko kunye ne-backup, iqonga le-virtualization kwi-VMware vSphere. Zonke iinkqubo ezivelisayo zifumaneka kwiziko ledatha eliphambili, kwaye ukuphindaphindwa koomatshini benyani kwenziwa kwinqanaba le-hypervisor, oku kuya kuphepha ukugcina ii-VM zivuliwe kwiziko ledatha yokugcina. Siphindaphinda i-database kunye nezicelo ezikhethekileyo zisebenzisa izixhobo ezakhelwe ngaphakathi kwaye sigcine ii-VM zivuliwe. Ukuba iziko ledatha eliphambili liyasilela, siqalisa iinkqubo kwindawo yokugcina idatha. Sikholelwa ukuba sinoomatshini abamalunga ne-100. Ngelixa iziko ledatha eliphambili lisebenza, isikhungo sedatha yokulinda sinokuqhuba iimeko zokuvavanya kunye nezinye iinkqubo ezinokuvalwa ukuba isikhungo sedatha esisiseko sitshintsha. Kwakhona kunokwenzeka ukuba sisebenzisa iindlela ezimbini zokuphindaphinda. Ukususela kumbono we-hardware, akukho nto iya kutshintsha.
Kwimeko ye-architecture ye-classical, siya kufaka kwiziko ledatha nganye inkqubo yokugcina i-hybridi kunye nokufikelela nge-FibreChannel, i-tiering, i-deduplication kunye nokunyanzeliswa (kodwa kungekhona kwi-intanethi), iiseva ze-8 kwindawo nganye, i-2 FibreChannel switches kunye ne-10G Ethernet. Ukuphindaphinda kunye nokutshintsha ulawulo kwi-architecture yakudala, sinokusebenzisa izixhobo ze-VMware (Replication + SRM) okanye izixhobo zeqela lesithathu, eziya kuba zincinci kwaye ngamanye amaxesha zilungele ngakumbi.
Umfanekiso ubonisa umzobo.
Xa usebenzisa iCisco HyperFlex, ulwakhiwo olulandelayo lufunyenwe:
Kwi-HyperFlex, ndisebenzise iiseva ezinezixhobo ezinkulu ze-CPU / RAM, kuba... Ezinye zezixhobo ziya kuya kumlawuli we-HyperFlex we-VM; ngokwe-CPU kunye nememori, ndiphinde ndiqwalasele uqwalaselo lwe-HyperFlex kancinci ukuze ungadlali kunye neCisco kunye nokuqinisekisa izixhobo zeeVM eziseleyo. Kodwa sinokuziyeka iiswitshi zeFibreChannel, kwaye asiyi kufuna izibuko ze-Ethernet kwiseva nganye; itrafikhi yasekhaya iyatshintshwa ngaphakathi kweFI.

Isisombululo seCisco HyperFlex sajika saba sixabiso eliphantsi nge-13%.
Imeko 2: ukwenziwa kwamaziko edatha amabini asebenzayo. Kule meko, siyila iqela elongeziweyo kwi-VMware.
I-architecture yeklasikhi iquka abancedisi be-virtualization, i-SAN (i-FC protocol) kunye neenkqubo ezimbini zokugcina ezikwazi ukufunda nokubhala kumthamo owoluliweyo phakathi kwazo. Kwinkqubo nganye yokugcina sibeka umthamo oluncedo wokugcina.
Kwi-HyperFlex sisenza nje iQela lokuNyula elinenani elifanayo leendawo kuzo zombini iisayithi. Kule meko, i-replication factor ye-2 + 2 isetyenzisiweyo.
Isiphumo lulungelelwaniso olulandelayo:

Kuzo zonke izibalo, andizange ndithathele ingqalelo isiseko senethiwekhi, iindleko zeziko ledatha, njl.: ziya kufana ne-architecture ye-classical kunye nesisombululo se-HyperFlex.
Ngokweendleko, i-HyperFlex yajika yaba yi-5% ebiza kakhulu. Kuyafaneleka ukuba uqaphele apha ukuba ngokwemigaqo ye-CPU / RAM izibonelelo ndibe ne-skew ye-Cisco, kuba kuqwalaselo ndizalise iziteshi zokulawula imemori ngokulinganayo. Iindleko ziphezulu kancinci, kodwa kungekhona ngomyalelo wobukhulu, obonisa ngokucacileyo ukuba i-hyperconvergence ayikho "ithoyizi yesityebi", kodwa inokukhuphisana nendlela eqhelekileyo yokwakha iziko ledatha. Oku kunokuba nomdla kwabo sele beneeseva ze-Cisco UCS kunye neziseko ezihambelana nazo.
Phakathi kweenzuzo, sifumana ukungabikho kweendleko zokulawula i-SAN kunye neenkqubo zokugcina, ukunyanzeliswa kwe-intanethi kunye nokunciphisa, indawo eyodwa yokungena yokuxhasa (i-virtualization, iiseva, nazo ziyinkqubo yokugcina), ukugcina indawo (kodwa kungekhona kuzo zonke iimeko), ukwenza lula umsebenzi.
Ngokuphathelele inkxaso, apha uyifumana kumthengisi omnye - Cisco. Ukujonga ngamava am kunye neeseva zeCisco UCS, ndiyayithanda; Akunyanzelekanga ukuba ndiyivule kwiHyperFlex, yonke into yasebenza ngokufanayo. Iinjineli ziphendula ngokukhawuleza kwaye azinakusombulula kuphela iingxaki eziqhelekileyo, kodwa kunye namatyala anzima. Ngamanye amaxesha ndiye ndibhekise kubo ngemibuzo: "Ngaba kuyenzeka ukwenza oku, ukujija?" okanye “Ndiqwalasele into apha, kwaye ayifuni ukusebenza. Nceda!" - baya kufumana ngomonde isikhokelo esiyimfuneko apho kwaye babonise izenzo ezichanekileyo; abayi kuphendula: "Sisombulula kuphela iingxaki ze-hardware."
