Lena inganekwane evame kakhulu emkhakheni we-server hardware. Eqinisweni, izixazululo ze-hyperconverged (lapho konke kukodwa) ziyadingeka ezintweni eziningi. Ngokomlando, izakhiwo zokuqala zakhiwe yi-Amazon kanye ne-Google ngezinsizakalo zabo. Khona-ke umqondo wawuwukwenza ipulazi lekhompiyutha kusuka kuma-node afanayo, ngayinye eyayinamadiski ayo. Konke lokhu kwahlanganiswa isoftware ethile yokwakha uhlelo (hypervisor) futhi yahlukaniswa yaba yimishini ebonakalayo. Umgomo oyinhloko ubuncane bomzamo wokusevisa i-node eyodwa kanye nobuncane bezinkinga lapho ukala: vele uthenge enye inkulungwane noma amabili amaseva afanayo bese uwaxhuma eduze. Empeleni, lawa amacala angawodwa, futhi kaningi sikhuluma ngenani elincane lama-node kanye nezakhiwo ezihluke kancane.
Kodwa ukuhlanganisa kusalokhu kufana - ukukhululeka okumangalisayo kokukala nokuphatha. Okubi ukuthi imisebenzi ehlukene idla izinsiza ngokuhlukile, futhi kwezinye izindawo kuzoba namadiski amaningi wendawo, kwezinye kuzoba ne-RAM encane, nokunye, okungukuthi, ngezinhlobo ezahlukene zemisebenzi, ukusetshenziswa kwezinsiza kuzokwehla.
Kuvele ukuthi ukhokha u-10-15% ngaphezulu ukuze kube lula ukusetha. Yilokhu okwasusa inganekwane esihlokweni. Sichithe isikhathi eside sifuna lapho ubuchwepheshe buzosetshenziswa ngokufanele, futhi sabuthola. Iqiniso liwukuthi iCisco yayingenazo izinhlelo zayo zokugcina, kodwa yayifuna imakethe yeseva ephelele. Futhi benza i-Cisco Hyperflex - isisombululo esinesitoreji sendawo kuma-node.
Futhi lokhu kuvele kwaba yisixazululo esihle kakhulu sezikhungo zedatha yokusekelayo (Ukubuyisela Inhlekelele). Ngizokutshela ukuthi kungani futhi kanjani manje. Futhi ngizokukhombisa izivivinyo zeqoqo.
Lapho kudingeka khona
I-Hyperconvergence yile:
- Ukudlulisa amadiski kumanodi wokubala.
- Ukuhlanganiswa okugcwele kwesistimu engaphansi yesitoreji nesistimu engaphansi yokwenza izinto ezibonakalayo.
- Ukudlulisa/ukuhlanganiswa nohlelo olungaphansi lwenethiwekhi.
Le nhlanganisela ikuvumela ukuthi usebenzise izici eziningi zesistimu yesitoreji ezingeni le-virtualization futhi konke kusuka kuwindi lokulawula elilodwa.
Enkampanini yethu, amaphrojekthi okuklama izikhungo zedatha ezingasasebenzi adingeka kakhulu, futhi isisombululo esihlanganisiwe ngokuvamile sikhethwa ngenxa yenqwaba yezinketho zokuphindaphinda (kufika ku-metrocluster) ngaphandle kwebhokisi.
Endabeni yezikhungo zedatha yokusekelayo, ngokuvamile sikhuluma ngendawo ekude esizeni esikolunye uhlangothi lwedolobha noma kwelinye idolobha ngokuphelele. Ikuvumela ukuthi ubuyisele izinhlelo ezibucayi uma kwenzeka ukwehluleka okuyingxenye noma okuphelele kwesikhungo esikhulu sedatha. Idatha yokuthengisa iphindwaphindwa njalo lapho, futhi lokhu kuphindaphinda kungaba sezingeni lesicelo noma ezingeni ledivayisi yokuvimba (isitoreji).
Ngakho-ke, manje ngizokhuluma ngokuklama kwesistimu nokuhlolwa, bese mayelana nezimo ezimbalwa zezinhlelo zokusebenza zangempela ezinedatha yokonga.
Uvivinyo
Isibonelo sethu siqukethe amaseva amane, ngayinye enamadrayivu ayi-10 e-SSD angu-960 GB. Kukhona idiski elizinikele lomsebenzi wokubhala kunqolobane nokugcina umshini obonakalayo wesevisi. Isixazululo ngokwaso inguqulo yesine. Eyokuqala iluhlaza ngokungagwegwesi (ukwahlulela ngezibuyekezo), eyesibili imanzi, eyesithathu isivele izinzile, futhi lokhu kungabizwa ngokuthi ukukhululwa ngemva kokuphela kokuhlolwa kwe-beta yomphakathi jikelele. Ngesikhathi sokuhlolwa angizange ngibone izinkinga, yonke into isebenza njengewashi.
Izinguquko ku-v4Inqwaba yeziphazamisi isilungisiwe.
Ekuqaleni, ipulatifomu yayingasebenza kuphela ne-VMware ESXi hypervisor futhi isekela inani elincane lamanodi. Futhi, inqubo yokuthunyelwa ayizange iphele ngempumelelo ngaso sonke isikhathi, ezinye izinyathelo kwadingeka ziqalwe kabusha, kube nezinkinga ngokubuyekezwa kwezinguqulo ezindala, idatha eku-GUI yayingaboniswa kahle ngaso sonke isikhathi (nakuba ngisajabulile ngokuboniswa kwamagrafu okusebenza. ), ngezinye izikhathi izinkinga zaphakama esibonakalayo nge-virtualization.
Manje zonke izinkinga zobuntwana sezilungisiwe, i-HyperFlex ingakwazi ukuphatha i-ESXi ne-Hyper-V, futhi kungenzeka ukuthi:
- Ukudala iqoqo eliluliwe.
- Ukudala iqoqo lamahhovisi ngaphandle kokusebenzisa i-Fabric Interconnect, kusuka ezindaweni ezimbili kuya kwezine (sithenga amaseva kuphela).
- Ikhono lokusebenza nezinhlelo zokugcina zangaphandle.
- Ukusekelwa kweziqukathi kanye ne-Kubernetes.
- Ukudalwa kwezindawo ezitholakalayo.
- Ukuhlanganiswa ne-VMware SRM uma ukusebenza okwakhelwe ngaphakathi kungagculisi.
I-architecture ayihlukile kakhulu kuzixazululo zezimbangi zayo ezinkulu; abazange bakhe ibhayisikili. Konke kusebenza ku-VMware noma i-Hyper-V yesikhulumi sokubona. I-Hardware isingathwe kumaseva e-Cisco UCS okuphathelene. Kukhona labo abazonda isiteji sobunzima obuhlobene bokusetha kokuqala, izinkinobho eziningi, uhlelo olungeyona into encane yezifanekiso nokuncika, kodwa kukhona nalabo abaye bafunda i-Zen, baphefumulelwe umbono futhi abasafuni. ukusebenza namanye amaseva.
Sizocubungula isixazululo se-VMware, njengoba isixazululo sadalelwa sona ekuqaleni futhi sinomsebenzi owengeziwe; I-Hyper-V yengezwe endleleni ukuze ihambisane nezimbangi futhi ihlangabezane nokulindelwe yimakethe.
Kukhona iqoqo lamaseva agcwele amadiski. Kunamadiski okugcina idatha (i-SSD noma i-HDD - ngokuya ngokuthanda kwakho nezidingo zakho), kunediski eyodwa ye-SSD yokugcinwa kwesikhashana. Lapho ubhala idatha ku-datastore, idatha igcinwa kusendlalelo se-caching (idiski ye-SSD enikelwe kanye ne-RAM yesevisi ye-VM). Ngokuhambisanayo, ibhulokhi yedatha ithunyelwa kumanodi kuqoqo (inani lamanodi lincike kusici sokuphindaphinda kweqoqo). Ngemuva kokuqinisekiswa okuvela kuwo wonke ama-node mayelana nokurekhoda okuphumelelayo, ukuqinisekiswa kokuqoshwa kuthunyelwa ku-hypervisor bese kuba ku-VM. Idatha erekhodiwe iyakhishwa, icindezelwe futhi ibhalwe kumadiski okugcina ngemuva. Ngesikhathi esifanayo, i-block enkulu ihlale ibhalwa kuma-disks okugcina futhi ngokulandelanayo, okunciphisa umthwalo kumadiski okugcina.
Ukukhipha kabili nokuminyanisa kuhlala kunikwe amandla futhi akukwazi ukukhutshazwa. Idatha ifundwa ngokuqondile kumadiski okugcina noma kunqolobane ye-RAM. Uma kusetshenziswa ukucushwa kwe-hybrid, ukufundwa kubuye kugcinwe kunqolobane ye-SSD.
Idatha ayiboshelwe endaweni yamanje yomshini obonakalayo futhi isatshalaliswa ngokulinganayo phakathi kwamanodi. Le ndlela ikuvumela ukuthi ulayishe wonke amadiski nezixhumi zenethiwekhi ngokulinganayo. Kunobubi obusobala: asikwazi ukunciphisa ukubambezeleka kokufunda ngangokunokwenzeka, njengoba kungekho siqinisekiso sokutholakala kwedatha endaweni. Kodwa ngikholelwa ukuthi lokhu kuwumhlatshelo omncane uma kuqhathaniswa nezinzuzo ezitholwayo. Ngaphezu kwalokho, ukubambezeleka kwenethiwekhi kufinyelele amanani anjalo kangangokuthi angathinti umphumela ophelele.
Isevisi ekhethekile ye-VM Cisco HyperFlex Data Platform isilawuli, esakhiwe endaweni ngayinye yokugcina, inesibopho sayo yonke i-logic yokusebenza ye-subsystem yediski. Ekucushweni kwethu kwe-VM yensizakalo, ama-vCPU ayisishiyagalombili kanye ne-72 GB ye-RAM yabelwe, engencane kangako. Ake ngikukhumbuze ukuthi umsingathi uqobo unama-core cores angama-28 kanye ne-512 GB ye-RAM.
Isevisi ye-VM inokufinyelela kumadiski aphathekayo ngokuqondile ngokudlulisela isilawuli se-SAS ku-VM. Ukuxhumana ne-hypervisor kwenzeka nge-module ekhethekile IOVisor, ebamba ukusebenza kwe-I/O, nokusebenzisa i-ejenti ekuvumela ukuthi uthumele imiyalo ku-hypervisor API. I-ejenti inesibopho sokusebenza ne-HyperFlex izifinyezo nama-clones.
Izinsiza zediski zifakwe ku-hypervisor njengamasheya e-NFS noma e-SMB (kuya ngohlobo lwe-hypervisor, qagela ukuthi ikuphi). Futhi ngaphansi kwe-hood, lolu uhlelo lwefayela olusabalalisiwe olukuvumela ukuthi wengeze izici zezinhlelo zokugcina ezigcwele zabadala: ukwabiwa kwevolumu emincane, ukucindezelwa nokuncishiswa, izifinyezo kusetshenziswa ubuchwepheshe be-Redirect-on-Write, ukuphindaphinda okuvumelanayo/okuvumelanayo.
Isevisi ye-VM inikeza ukufinyelela ku-WEB management interface ye-HyperFlex subsystem. Kukhona ukuhlanganiswa ne-vCenter, futhi imisebenzi eminingi yansuku zonke ingenziwa kuyo, kodwa izitolo zedatha, isibonelo, kulula kakhulu ukusika kukhamera yewebhu ehlukile uma usuvele ushintshele ku-interface ye-HTML5 esheshayo, noma usebenzisa iklayenti le-Flash eligcwele. ngokuhlanganiswa okuphelele. Kukhamera yewebhu yesevisi ungabuka ukusebenza kanye nesimo esinemininingwane sohlelo.
Kukhona olunye uhlobo lwe-node ku-cluster - ama-computing nodes. Lawa angaba amaseva e-rack noma ama-blade ngaphandle kwamadiski akhelwe ngaphakathi. Lawa maseva angasebenzisa ama-VM idatha yawo egcinwa kumaseva anamadiski. Ngokombono wokufinyelela idatha, akukho mehluko phakathi kwezinhlobo zama-node, ngoba ukwakheka kuhilela ukukhishwa endaweni ebonakalayo yedatha. Isilinganiso esiphezulu samanodi ekhompuyutha kumanodi okugcina ngu-2:1.
Ukusebenzisa ama-comute node kukhulisa ukuguquguquka lapho sikala izinsiza zeqoqo: akudingeki ukuthi sithenge ama-node engeziwe ngamadiski uma sidinga i-CPU/RAM kuphela. Ngaphezu kwalokho, singangeza ikheji ye-blade futhi silondoloze ekubekweni kwe-rack yamaseva.
Njengomphumela, sineplathifomu ye-hyperconverged enezici ezilandelayo:
- Kufika kumanodi angama-64 kuqoqo (kufika kuzindawo zokugcina ezingama-32).
- Inani elincane lamanodi kuqoqo zintathu (amabili eqoqo le-Edge).
- Indlela yokuphindaphinda idatha: ukwenza isibuko nge-replication factor 2 kanye no-3.
- Iqoqo leMetro.
- Ukuphindaphinda kwe-Asynchronous VM kwelinye iqoqo le-HyperFlex.
- Ukuhlelwa kokushintshela ama-VM kusikhungo sedatha esikude.
- Izifinyezo zomdabu zisebenzisa ubuchwepheshe bokuqondisa kabusha-on-Bhala.
- Kufika ku-1 PB yesikhala esisebenzisekayo kusici sokuphindaphinda esingu-3 futhi ngaphandle kokuphindaphinda. Asinaki i-replication factor 2, ngoba lena akuyona inketho yokuthengisa okubucayi.
Okunye okuhlanganisayo okukhulu ukuphatha kalula nokusatshalaliswa. Zonke izingqinamba zokusetha amaseva e-UCS zinakekelwa yi-VM ekhethekile elungiswe onjiniyela bakwaCisco.

I-Bold ikhombisa amanani ngemuva kwalokho okungekho ukwanda kokukhiqiza, kwesinye isikhathi ukuwohloka kuyabonakala. Lokhu kungenxa yokuthi sinqunyelwe ukusebenza kwenethiwekhi/abalawuli/amadiski.
- Okulandelanayo kufundeka 4432 MB/s.
- Okulandelanayo bhala 804 MB/s.
- Uma isilawuli esisodwa sehluleka (ukwehluleka komshini obonakalayo noma umsingathi), ukwehla kokusebenza kukabili.
- Uma idiski yokugcina ihluleka, ukudonswa phansi kungu-1/3. Ukwakhiwa kabusha kwediski kuthatha u-5% wezinsiza zesilawuli ngasinye.
Kubhulokhi encane, sinqunyelwe ukusebenza kwesilawuli (umshini obonakalayo), i-CPU yayo ilayishwe ku-100%, futhi lapho ibhulokhi ikhula, sinqunyelwe umkhawulokudonsa wechweba. I-10 Gbps ayanele ukuvula amandla esistimu ye-AllFlash. Ngeshwa, amapharamitha wesitendi sedemo esinikeziwe awasivumeli ukuthi sihlole ukusebenza ku-40 Gbit/s.
Ngombono wami ovela ekuhlolweni nasekufundeni izakhiwo, ngenxa ye-algorithm ebeka idatha phakathi kwabo bonke ababungazi, sithola ukusebenza okulinganiselwe, okubikezelwe, kodwa lokhu futhi kuwumkhawulo lapho kufundwa, ngoba kungenzeka ukuthi ukhiphe okuningi kumadiski wendawo, lapha ingase igcine inethiwekhi ekhiqiza kakhulu, isibonelo, i-FI ku-40 Gbit/s iyatholakala.
Futhi, idiski eyodwa yokugcinwa kwesikhashana kanye nokukhishwa kwesikhashana kungase kube umkhawulo; empeleni, kule testbed singabhalela amadiski amane e-SSD. Kungaba kuhle ukukwazi ukukhulisa inani lamadrayivu e-caching futhi ubone umehluko.
Ukusetshenziswa kwangempela
Ukuze uhlele isikhungo sedatha eyisipele, ungasebenzisa izindlela ezimbili (asicabangi ukubeka ikhophi yasenqolobaneni kusayithi elikude):
- I-Active-Passive. Zonke izinhlelo zokusebenza zisingathwa esikhungweni sedatha esikhulu. Ukuphindaphinda kuyavumelana noma ku-asynchronous. Uma isikhungo sedatha esiyinhloko sihluleka, sidinga ukwenza isipele sisebenze. Lokhu kungenziwa ngesandla/imibhalo/izinhlelo zokusebenza ze-orchestration. Lapha sizothola i-RPO ehambisana nemvamisa yokuphindaphinda, futhi i-RTO incike ekuphenduleni kanye namakhono omlawuli kanye nekhwalithi yokuthuthukiswa/ukulungisa iphutha lohlelo lokushintsha.
- Iyasebenza. Kulesi simo, kukhona ukuphindaphinda okuvumelanayo kuphela; ukutholakala kwezikhungo zedatha kunqunywa ikhoramu/i-arbiter etholakala ngokuqinile kusayithi lesithathu. I-RPO = 0, futhi i-RTO ingafinyelela ku-0 (uma uhlelo lokusebenza luvumela) noma ilingane nesikhathi se-faillover se-node kuqoqo le-virtualization. Ezingeni le-virtualization, iqoqo elinwetshiwe (Metro) liyakhiwa elidinga isitoreji Esisebenzayo.
Ngokuvamile sibona ukuthi amaklayenti asevele esebenzise isakhiwo esinesistimu yokugcina yakudala esikhungweni sedatha esikhulu, ngakho siklama enye yokuphindaphinda. Njengoba ngishilo, i-Cisco HyperFlex inikezela ngokuphindaphinda okungavumelaniyo kanye nokudalwa kweqoqo le-virtualization elinwetshiwe. Ngesikhathi esifanayo, asidingi isistimu yokugcina ezinikele yeleveli ye-Midrange nangaphezulu enemisebenzi ebizayo yokuphindaphinda kanye nokufinyelela kwedatha Okusebenzayo Okusebenzayo kumasistimu wokulondoloza amabili.
Isimo 1: Sinezikhungo zedatha eziyisisekelo neziyisipele, inkundla yokwenza izinto ezibonakalayo ku-VMware vSphere. Zonke izinhlelo ezikhiqizayo zitholakala esikhungweni sedatha esiyinhloko, futhi ukuphindaphinda kwemishini ebonakalayo kwenziwa ezingeni le-hypervisor, lokhu kuzogwema ukugcina ama-VM evuliwe esikhungweni sedatha yokusekelayo. Siphindaphinda imininingwane yolwazi nezinhlelo zokusebenza ezikhethekile sisebenzisa amathuluzi akhelwe ngaphakathi futhi sigcina ama-VM evuliwe. Uma isikhungo sedatha esiyinhloko sihluleka, sethula amasistimu esikhungweni sedatha eyisipele. Sikholelwa ukuthi cishe sinemishini ebonakalayo eyi-100. Ngenkathi isikhungo sedatha esiyinhloko sisebenza, isikhungo sedatha esilindile singasebenzisa izindawo zokuhlola namanye amasistimu angavalwa uma isikhungo sedatha esiyinhloko sishintsha. Kungenzeka futhi ukuthi sisebenzisa izindlela ezimbili zokuphindaphinda. Ngokombono we-hardware, akukho okuzoshintsha.
Endabeni yezakhiwo zakudala, sizofaka esikhungweni ngasinye sedatha isistimu yokugcina eyingxube enokufinyelela nge-FibreChannel, i-tiering, deduplication kanye nokucindezela (kodwa hhayi ku-inthanethi), amaseva angu-8 kusayithi ngalinye, ama-switch we-FibreChannel angu-2 kanye ne-10G Ethernet. Ukuphatha ukuphindaphinda nokushintsha ekwakhiweni kwezakhiwo zakudala, singasebenzisa amathuluzi e-VMware (Replication + SRM) noma amathuluzi ezinkampani zangaphandle, azoshibhe kancane futhi ngezinye izikhathi alungele kakhudlwana.
Umfanekiso ubonisa umdwebo.
Uma usebenzisa i-Cisco HyperFlex, kutholakala lezi zakhiwo ezilandelayo:
Ku-HyperFlex, ngisebenzise amaseva anezinsiza ezinkulu ze-CPU/RAM, ngoba... Ezinye zezinsiza zizoya ku-VM yesilawuli se-HyperFlex; ngokuya nge-CPU nenkumbulo, ngaze ngalungisa kabusha ukucushwa kwe-HyperFlex kancane ukuze ngingadlali kanye ne-Cisco futhi ngiqinisekise izinsiza zama-VM asele. Kodwa singaziyeka izinguquko ze-FibreChannel, futhi ngeke sidinge izimbobo ze-Ethernet zeseva ngayinye; ithrafikhi yendawo iyashintshwa ngaphakathi kwe-FI.
Umphumela kube ukucushwa okulandelayo kwesikhungo ngasinye sedatha:

Ngokwakhiwa kwe-classical, ngikhethe umthengisi ozisungule njengomkhiqizi wekhwalithi ephezulu futhi ongabizi. Kuzo zombili izinketho, ngisebenzise isaphulelo esijwayelekile sesixazululo esithile, futhi ngenxa yalokho ngathola izintengo zangempela.
Isixazululo seCisco HyperFlex sishibhe ngo-13%.
Isimo 2: ukudalwa kwezikhungo zedatha ezimbili ezisebenzayo. Kulesi simo, siklama iqoqo elinwetshiwe ku-VMware.
Isakhiwo sakudala siqukethe amaseva e-virtualization, i-SAN (iphrothokholi ye-FC) kanye nezinhlelo ezimbili zokugcina ezingakwazi ukufunda nokubhala kuvolumu enwetshiwe phakathi kwazo. Kusistimu ngayinye yokugcina sibeka umthamo owusizo wokugcina.
Kwa-HyperFlex simane sakhe i-Stretch Cluster enenombolo efanayo yamanodi kuzo zombili izingosi. Kulokhu, i-replication factor engu-2+2 isetshenziswa.
Umphumela uwukucushwa okulandelayo:
izakhiwo zakudala
I-HyperFlex
Amaseva
Iseva engu-16 x 1U (384 GB RAM, 2 x Intel Gold 6132, FC HBA, 2 x 10G NIC)
16 x HX240C-M5L (512 GB RAM, 2 x Intel Gold 6132, 1,6 TB NVMe, 12 x 3,8 TB SSD, VIC 1387)

Kuzo zonke izibalo, angizange ngicabangele ingqalasizinda yenethiwekhi, izindleko zesikhungo sedatha, njll.: zizofana nezakhiwo ze-classical kanye nesisombululo se-HyperFlex.
Mayelana nezindleko, i-HyperFlex ibonakale ibiza kakhulu ngo-5%. Kuyaqapheleka lapha ukuthi ngokwezinsiza ze-CPU/RAM ngine-skew ye-Cisco, ngoba ekucushweni ngigcwalise iziteshi zesilawuli sememori ngokulinganayo. Izindleko ziphakeme kancane, kodwa hhayi ngomyalelo wobukhulu, okubonisa ngokucacile ukuthi i-hyperconvergence ayiyona "ithoyizi labacebile", kodwa ingaqhudelana nendlela evamile yokwakha isikhungo sedatha. Lokhu kungase futhi kube nentshisekelo kulabo asebevele banamaseva e-Cisco UCS nengqalasizinda ehambisana nawo.
Phakathi kwezinzuzo, sithola ukungabikho kwezindleko zokuphatha i-SAN kanye nezinhlelo zokulondoloza, ukucindezelwa kwe-inthanethi nokuphindaphinda, indawo eyodwa yokungena yokusekelwa (i-virtualization, amaseva, nawo ayizinhlelo zokugcina), ukonga isikhala (kodwa hhayi kuzo zonke izimo), ukwenza lula ukusebenza.
Ngokuqondene nokusekelwa, lapha uthola kumthengisi oyedwa - Cisco. Uma sibheka isipiliyoni sami ngamaseva weCisco UCS, ngiyayithanda; bekungadingeki ukuthi ngiyivule kuHyperFlex, konke kusebenze ngendlela efanayo. Onjiniyela baphendula ngokushesha futhi abakwazi ukuxazulula izinkinga ezijwayelekile kuphela, kodwa futhi namacala anzima. Kwesinye isikhathi ngibaphendukela ngemibuzo: "Kungenzeka yini ukwenza lokhu, ukugoqa?" noma “Ngilungise okuthile lapha, futhi akufuni ukusebenza. Usizo!" - bazothola ngokubekezela umhlahlandlela odingekayo lapho futhi baveze izenzo ezifanele; ngeke baphendule: "Sixazulula izinkinga zehadiwe kuphela."
