Siyaqhubeka ukukwazisa kwinkqubo ye-Cisco HyperFlex hyperconverged.
Ngo-Epreli ka-2019, iCisco iphinda iqhube uthotho lwemiboniso yesisombululo esitsha se-hyperconverged Cisco HyperFlex kwimimandla yaseRashiya naseKazakhstan. Ungabhalisela umboniso usebenzisa ifom yempendulo ngokulandela ikhonkco. Dibana nathi!
Ngaphambili sapapasha inqaku malunga novavanyo lomthwalo owenziwe yi-ESG Lab ezimeleyo kwi-2017. Kwi-2018, ukusebenza kwesisombululo seCisco HyperFlex (inguqulo ye-HX 3.0) iphuculwe kakhulu. Ukongeza, izisombululo ezikhuphisanayo nazo ziyaqhubeka nokuphucula. Yiyo loo nto sipapasha uguqulelo olutsha, lwamva nje lwemilinganiselo yoxinzelelo lweESG.
Ehlotyeni le-2018, i-laboratory ye-ESG iphinda ifanise i-Cisco HyperFlex kunye nabakhuphisana nabo. Ukuthathela ingqalelo indlela yangoku yokusebenzisa izisombululo ezichazwe kwiSoftware, abavelisi bamaqonga afanayo nabo bongezwa kuhlalutyo lokuthelekisa.
Ulungelelwaniso lovavanyo
Njengenxalenye yovavanyo, i-HyperFlex yathelekiswa neenkqubo ezimbini ezipheleleyo ze-hyperconverged ezifakwe kwiiseva eziqhelekileyo ze-x86, kunye nesofthiwe enye kunye nesisombululo se-hardware. Uvavanyo lwenziwa kusetyenziswa isoftware eqhelekileyo kwiinkqubo ze-hyperconverged - HCIBench, esebenzisa isixhobo se-Oracle Vdbench kwaye izenzele inkqubo yokuvavanya. Ngokukodwa, i-HCIBench idala ngokuzenzekelayo oomatshini benyani, ilungelelanisa umthwalo phakathi kwabo kwaye ivelise iingxelo ezifanelekileyo neziqondakalayo.
Oomatshini abayi-140 benyani baye badalwa kwiqela ngalinye (35 kwindawo yeqela ngalinye). Umatshini ngamnye wenyani wasebenzisa i-4 vCPU, i-4 GB RAM. Idiski yeVM yendawo yayiyi-16 GB kunye nediski eyongezelelweyo yayiyi-40 GB.
Olu lungelelwaniso lweqela lulandelayo luthathe inxaxheba kuvavanyo:
- iqoqo ezine ze-Cisco HyperFlex 220C nodes 1 x 400 GB SSD ye-cache kunye ne-6 x 1.2 TB SAS HDD yedatha;
- umthengisi okhuphisanayo Iqela leenodes ezine 2 x 400 GB SSD ye-cache kunye ne-4 x 1 TB SATA HDD yedatha;
- okhuphisanayo noMthengisi B iqoqo leenodi ezine 2 x 400 GB SSD ye-cache kunye ne-12 x 1.2 TB SAS HDD yedatha;
- competitor Vendor C cluster of four nodes 4 x 480 GB SSD for cache and 12 x 900 GB SAS HDD for data.
Iiprosesa kunye ne-RAM yazo zonke izisombululo zazifana.
Uvavanyo lwenani loomatshini benyani
Uvavanyo lwaqala ngomthwalo womsebenzi owenzelwe ukulinganisa uvavanyo oluqhelekileyo lwe-OLTP: ukufunda / ukubhala (RW) 70% / 30%, 100% iRandom epheleleyo kunye nethagethi ye-800 IOPS ngomatshini we-virtual (VM). Uvavanyo lwenziwa kwii-VM ezili-140 kwiqela ngalinye iiyure ezintathu ukuya kwezine. Injongo yovavanyo kukugcina ukubhala ngokusemva kwii-VM ezininzi kangangoko kunokwenzeka ukuya kwi-5 milliseconds okanye ngaphantsi.
Njengomphumo wovavanyo (jonga igrafu engezantsi), i-HyperFlex yayikuphela kweqonga eligqibe olu vavanyo nge-VM yokuqala ye-140 kunye ne-latencies engaphantsi kwe-5 ms (4,95 ms). Kwiqela ngalinye lamanye, uvavanyo lwaphinda lwaqalwa ukuze kuhlengahlengiswe ngokulinga inani le-VMs kwithagethi ye-latency ye-5 ms ngokuphindaphindiweyo.
Umthengisi A uphathe ngempumelelo ii-VM ze-70 kunye nexesha lokuphendula eliphakathi kwe-4,65 ms.
Umthengisi B uzuze ukubambezeleka okufunekayo kwe-5,37 ms. kuphela nge-36 VMs.
Umthengisi u-C wakwazi ukuphatha i-48 oomatshini benyani kunye nexesha lokuphendula le-5,02 ms
Ukulinganisa Umthwalo weseva yeSQL
Okulandelayo, iLabhu yeESG ilingise umthwalo weSeva yeSQL. Uvavanyo lusebenzise ubungakanani bebhloko obahlukeneyo kunye nemilinganiselo yokufunda / yokubhala. Olu vavanyo lwaqhutywa koomatshini abangama-140.
Njengoko kubonisiwe kumzobo ongezantsi, iqela leCisco HyperFlex liphumelele abathengisi A kunye no-B kwi-IOPS phantse kabini, kunye nomthengisi C ngaphezu kwamaxesha amahlanu. Ixesha eliqhelekileyo lokuphendula leCisco HyperFlex laliyi-8,2 ms. Ukuthelekisa, ixesha lokuphendula eliqhelekileyo kuMthengisi A laliyi-30,6 ms, kuMthengisi B ngu-12,8 ms, kwaye kuMthengisi C ngu-10,33 ms.
Uqwalaselo olunika umdla lwenziwa kulo lonke uvavanyo. Umthengisi B ubonise ukuguquguquka okubalulekileyo ekusebenzeni okuqhelekileyo kwi-IOPS kwiiVM ezahlukeneyo. Oko kukuthi, umthwalo wasasazwa ngokungalingani kakhulu, ezinye iiVM zasebenza ngexabiso eliphakathi kwe-1000 IOPS +, kwaye ezinye - ngexabiso le-64 IOPS. I-Cisco HyperFlex kulo mzekelo ibonakala izinzile kakhulu, zonke ii-VM ze-140 zifumene i-avareji ye-600 IOPS kwi-subsystem yokugcina, oko kukuthi, umthwalo phakathi koomatshini benyani yasasazwa ngokulinganayo.
Kubalulekile ukuqaphela ukuba usasazo olungalinganiyo olunjalo lwe-IOPS kubo bonke oomatshini bokwenene kumthengisi B lujongwe kuphinda-phindo ngalunye lovavanyo.
Kwimveliso yokwenyani, le ndlela yokuziphatha yenkqubo inokuba yingxaki enkulu kubalawuli, enyanisweni, oomatshini bomntu ngamnye baqala ngokukhenkceza kwaye akukho ndlela yokulawula le nkqubo. Indlela yodwa, engaphumelelanga kakhulu yokulayisha ibhalansi, xa usebenzisa isisombululo esivela kumthengisi B, kukusebenzisa enye okanye enye iQoS okanye ukuphunyezwa kokulinganisa.
isiphelo
Makhe sicinge malunga nokuba yintoni iCisco Hyperflex inamashini angama-140 nge-node yomzimba e-1 xa ithelekiswa ne-70 okanye ngaphantsi kwezinye izisombululo? Kwishishini, oku kuthetha ukuba ukuxhasa inani elifanayo lezicelo kwi-Hyperflex, udinga amaxesha angama-2 ama-node ambalwa kunezisombululo zokhuphiswano, oko kukuthi. inkqubo yokugqibela iya kuba sezantsi kakhulu. Ukuba songeza apha inqanaba lokuzenzekelayo kuyo yonke imisebenzi yokugcina inethiwekhi, iiseva kunye neqonga lokugcina i-HX Data Platform, kuyacaca ukuba kutheni izixazululo zeCisco Hyperflex zikhawuleza ukufumana ukuthandwa kwimarike.
Ngokubanzi, iiLabhu ze-ESG ziqinisekisile ukuba i-Cisco HyperFlex Hybrid HX 3.0 ihambisa ngokukhawuleza kunye nokusebenza okungaguqukiyo kunezinye izisombululo ezinokuthelekiswa.
Kwangelo xesha, amaqela e-HyperFlex hybrid ayephambi kwabakhuphisanayo ngokwemiqathango ye-IOPS kunye neLatency. Okubaluleke ngokulinganayo, ukusebenza kwe-HyperFlex kwaphunyezwa ngomthwalo osasazwe kakuhle kulo lonke ugcino.
Masikukhumbuze ukuba ungasibona isisombululo seCisco Hyperflex kwaye uqinisekise amandla ayo ngoku. Inkqubo iyafumaneka ukuze iboniswe kuye wonke umntu:
