Tikupitiliza kukudziwitsani za Cisco HyperFlex hyperconverged system.
Mu Epulo 2019, Cisco ikuchitanso ziwonetsero zingapo za njira yatsopano yolumikizira Cisco HyperFlex m'magawo a Russia ndi Kazakhstan. Mutha kulembetsa pachiwonetsero pogwiritsa ntchito fomu yoyankha potsatira ulalo. Titsatireni!
Tidasindikiza m'mbuyomu nkhani yokhudza kuyezetsa katundu komwe kunachitika ndi ESG Lab yodziyimira payokha mu 2017. Mu 2018, magwiridwe antchito a Cisco HyperFlex solution (mtundu wa HX 3.0) asintha kwambiri. Kuphatikiza apo, mayankho opikisana nawonso akupitilizabe kukonza. Ichi ndichifukwa chake tikusindikiza mtundu watsopano, waposachedwa kwambiri wa ma benchmark a ESG opsinjika.
M'chilimwe cha 2018, labotale ya ESG idafaniziranso Cisco HyperFlex ndi omwe akupikisana nawo. Poganizira zomwe zikuchitika masiku ano kugwiritsa ntchito mayankho ofotokozedwa ndi Mapulogalamu, opanga mapulatifomu ofanana nawo adawonjezeredwa pakuwunika kofananira.
Kuyesa masinthidwe
Monga gawo la kuyesako, HyperFlex idafaniziridwa ndi makina awiri amtundu wa hyperconverged omwe amaikidwa pa ma seva wamba a x86, komanso ndi pulogalamu imodzi ndi yankho la hardware. Kuyesa kunachitika pogwiritsa ntchito pulogalamu yokhazikika yamakina a hyperconverged - HCIBench, yomwe imagwiritsa ntchito chida cha Oracle Vdbench ndikusinthira kuyesako. Makamaka, HCIBench imapanga makina enieni, imagwirizanitsa katundu pakati pawo ndikupanga malipoti osavuta komanso omveka.
Makina pafupifupi 140 adapangidwa pagulu lililonse (35 pamagulu onse). Makina aliwonse ogwiritsa ntchito 4 vCPUs, 4 GB RAM. VM disk yapafupi inali 16 GB ndipo disk yowonjezera inali 40 GB.
Masanjidwe otsatirawa adatengapo gawo pakuyesa:
- gulu la anayi Cisco HyperFlex 220C nodes 1 x 400 GB SSD kwa cache ndi 6 x 1.2 TB SAS HDD kwa deta;
- mpikisano Wogulitsa Gulu la node zinayi 2 x 400 GB SSD ya cache ndi 4 x 1 TB SATA HDD ya deta;
- mpikisano Wogulitsa B gulu la mfundo zinayi 2 x 400 GB SSD ya cache ndi 12 x 1.2 TB SAS HDD ya deta;
- mpikisano Wogulitsa C gulu la mfundo zinayi 4 x 480 GB SSD ya cache ndi 12 x 900 GB SAS HDD ya data.
Mapurosesa ndi RAM ya mayankho onse anali ofanana.
Yesani kuchuluka kwa makina enieni
Kuyesa kunayamba ndi kuchuluka kwa ntchito komwe kumapangidwira kutengera mayeso wamba a OLTP: werengani/lemba (RW) 70%/30%, 100% FullRandom ndi chandamale cha 800 IOPS pa makina aliwonse (VM). Kuyesedwa kunachitika pa 140 VM pagulu lililonse kwa maola atatu kapena anayi. Cholinga cha mayesowa ndikusunga kuchedwa kwa ma VM ambiri momwe mungathere mpaka ma milliseconds 5 kapena kutsika.
Chifukwa cha kuyesedwa (onani chithunzi pansipa), HyperFlex inali nsanja yokhayo yomwe inamaliza mayesowa ndi ma VM oyambirira a 140 ndi latencies pansi pa 5 ms (4,95 ms). Pamagulu ena aliwonse, mayesowo adayambidwanso kuti asinthe moyeserera kuchuluka kwa ma VM ku chandamale latency ya 5 ms kubwereza kangapo.
Wogulitsa A adagwira bwino ma VM 70 ndi nthawi yoyankha ya 4,65 ms.
Wogulitsa B adapeza latency yofunikira ya 5,37 ms. kokha ndi 36 VMs.
Wogulitsa C adatha kugwiritsa ntchito makina pafupifupi 48 ndi nthawi yoyankha ya 5,02 ms
SQL Server Load Emulation
Kenako, ESG Lab idatengera kuchuluka kwa SQL Server. Mayesowa adagwiritsa ntchito makulidwe osiyanasiyana a block ndikuwerengera / kulemba. Mayesowa adayendetsedwanso pamakina pafupifupi 140.
Monga momwe tawonetsera pachithunzichi, gulu la Cisco HyperFlex linapambana mavenda A ndi B mu IOPS pafupifupi kawiri, ndi wogulitsa C kuposa kasanu. Pafupifupi nthawi yoyankha ya Cisco HyperFlex inali 8,2 ms. Poyerekeza, nthawi yoyankha kwa Wogulitsa A inali 30,6 ms, kwa Wogulitsa B anali 12,8 ms, ndipo kwa Wogulitsa C anali 10,33 ms.
Kuyang'ana kochititsa chidwi kunachitika panthawi ya mayesero onse. Wogulitsa B adawonetsa kusiyana kwakukulu pamachitidwe a IOPS pa ma VM osiyanasiyana. Ndiye kuti, katunduyo adagawidwa mosagwirizana kwambiri, ma VM ena adagwira ntchito ndi mtengo wapakati wa 1000 IOPS +, ndipo ena - ndi mtengo wa 64 IOPS. Cisco HyperFlex pankhaniyi inkawoneka yokhazikika, ma VM onse 140 adalandira pafupifupi 600 IOPS kuchokera kuzinthu zosungirako, ndiye kuti, katundu pakati pa makinawo adagawidwa mofanana kwambiri.
Ndikofunika kuzindikira kuti kugawa kosagwirizana koteroko kwa IOPS pamakina pafupifupi kwa ogulitsa B kumawonedwa pakuyesa kulikonse.
Pakupanga kwenikweni, machitidwe a dongosololi atha kukhala vuto lalikulu kwa oyang'anira; M'malo mwake, makina amunthu payekha amayamba kuzizira ndipo palibe njira yowongolera izi. Njira yokhayo, yosapambana kwambiri yolembetsera bwino, mukamagwiritsa ntchito yankho kuchokera kwa ogulitsa B, ndikugwiritsa ntchito imodzi kapena ina QoS kapena kukhazikitsa kulinganiza.
Pomaliza
Tiyeni tiganizire zomwe Cisco Hyperflex ili ndi makina pafupifupi 140 pa mfundo imodzi yakuthupi motsutsana ndi 1 kapena kuchepera panjira zina? Kwa bizinesi, izi zikutanthauza kuti kuthandizira chiwerengero chofanana cha mapulogalamu pa Hyperflex, mukufunikira ma node a 70 nthawi zochepa kusiyana ndi zothetsera mpikisano, i.e. dongosolo lomaliza lidzakhala lotsika mtengo kwambiri. Ngati tiwonjezera apa mulingo wa automation wa ntchito zonse zosungira maukonde, ma seva ndi nsanja yosungirako HX Data Platform, zikuwonekeratu chifukwa chake mayankho a Cisco Hyperflex akutchuka kwambiri pamsika.
Ponseponse, ESG Labs yatsimikizira kuti Cisco HyperFlex Hybrid HX 3.0 imapereka magwiridwe antchito mwachangu komanso mosasinthasintha kuposa mayankho ena ofanana.
Nthawi yomweyo, magulu osakanizidwa a HyperFlex analinso patsogolo pa opikisana nawo malinga ndi IOPS ndi Latency. Chofunikanso chimodzimodzi, machitidwe a HyperFlex adakwaniritsidwa ndi katundu wogawidwa bwino kwambiri posungirako.
Tikukumbutseni kuti mutha kuwona yankho la Cisco Hyperflex ndikutsimikizira kuthekera kwake pompano. Dongosololi likupezeka kuti liwonetsedwe kwa aliyense:
