Isu tinoenderera mberi nekukuzivisa iwe kuCisco HyperFlex hyperconverged system.
Muna Kubvumbi 2019, Cisco iri kuita zvakare nhevedzano yekuratidzira kweiyo nyowani hyperconverged mhinduro Cisco HyperFlex mumatunhu eRussia neKazakhstan. Unogona kusaina kuratidziro uchishandisa fomu remhinduro nekutevera chinongedzo. Join us!
Isu takamboburitsa chinyorwa nezve miyedzo yemutoro yakaitwa neyakazvimiririra ESG Lab muna 2017. Muna 2018, kuita kweCisco HyperFlex mhinduro (vhezheni HX 3.0) yakavandudza zvakanyanya. Mukuwedzera, mhinduro dzemakwikwi dzinoramba dzichivandudza. Ndosaka tiri kuburitsa imwe, yazvino vhezheni yeESG's stress benchmarks.
Muzhizha ra2018, iyo ESG marabhoritari yakaenzanisa zvakare Cisco HyperFlex nevakwikwidzi vayo. Tichifunga nezvemaitiro azvino ekushandisa maSoftware-defined solutions, vagadziri vemapuratifomu akafanana vakawedzerwawo kuongororo yekuenzanisa.
Magadzirirwo ebvunzo
Sechikamu chekuyedzwa, HyperFlex yakaenzaniswa neaviri akazara software hyperconverged masisitimu akaiswa pane akajairwa x86 maseva, pamwe chete nesoftware imwe uye hardware mhinduro. Kuyedzwa kwakaitwa pachishandiswa yakajairwa software ye hyperconverged masisitimu - HCIBench, inoshandisa iyo Oracle Vdbench chishandiso uye inogadzirisa maitiro ekuyedza. Kunyanya, HCIBench inogadzira otomatiki michina, inorongedza mutoro pakati pavo uye inogadzira mishumo iri nyore uye inonzwisisika.
140 chaiwo michina yakagadzirwa pachikwata (35 per cluster node). Muchina wega wega wakashandisa 4 vCPUs, 4 GB RAM. Iyo yemunharaunda VM disk yaive 16 GB uye imwe dhisiki yaive 40 GB.
Izvo zvinotevera cluster zvigadziriso zvakatora chikamu mukuyedzwa:
- cluster yechina Cisco HyperFlex 220C nodes 1 x 400 GB SSD ye cache uye 6 x 1.2 TB SAS HDD yedata;
- competitor Vendor A cluster of four nodes 2 x 400 GB SSD for cache uye 4 x 1 TB SATA HDD yedata;
- mukwikwidzi Vendor B cluster yemanode mana 2 x 400 GB SSD yecache uye 12 x 1.2 TB SAS HDD yedata;
- mukwikwidzi Vendor C cluster yemanodhi mana 4 x 480 GB SSD yecache uye 12 x 900 GB SAS HDD yedata.
Iwo ma processor uye RAM yeese mhinduro aive akafanana.
Edzai nhamba yemashini chaiwo
Kuedzwa kwakatanga nebasa rakagadzirirwa kutevedzera chiyero cheOLTP bvunzo: kuverenga/kunyora (RW) 70%/30%, 100% FullRandom ine chinangwa che800 IOPS pamushini wega wega (VM). Muedzo wakaitwa pa140 VM musumbu rega rega kwemaawa matatu kusvika mana. Chinangwa chebvunzo ndechekuchengeta nguva dzekunyora paVM dzakawanda sezvinobvira kusvika 5 milliseconds kana kudzika.
Nekuda kwekuyedzwa (ona girafu pazasi), HyperFlex ndiyo chete chikuva chakapedza bvunzo iyi nekutanga 140 VM uye ine latencies pazasi 5 ms (4,95 ms). Kune rimwe nerimwe remamwe masumbu, bvunzo yakatangwa patsva kuitira kuyedza kugadzirisa nhamba yeVM kune tarisiro latency ye5 ms pamusoro akati wandei iterations.
Mutengesi A akabudirira kubata 70 VM neavhareji yekupindura nguva ye4,65 ms.
Mutengesi B akawana latency inodiwa ye5,37 ms. chete ne36 VMs.
Mutengesi C akakwanisa kubata 48 chaiwo michina ine nguva yekupindura ye5,02 ms
SQL Server Load Emulation
Tevere, ESG Lab yakateedzera iyo SQL Server mutoro. Muedzo wakashandisa masaizi ebhuroka akasiyana uye kuverenga / kunyora zviyero. Muedzo uyu wakaitwawo pamichina zana nemakumi mana.
Sezvinoratidzwa pamufananidzo uri pazasi, iyo Cisco HyperFlex cluster yakapfuura vatengesi A uye B muIOPS nekanenge kaviri, uye mutengesi C nekanopfuura kashanu. Avhareji yekupindura nguva yeCisco HyperFlex yaive 8,2 ms. Kuenzanisa, nguva yeavhareji yekupindura Mutengesi A yaive 30,6 ms, yeMutengesi B yaive 12,8 ms, uye yeMutengesi C yaive 10,33 ms.
Kucherechedzwa kunonakidza kwakaitwa panguva yese yebvunzo. Mutengesi B airatidza mutsauko wakakura muavhareji kuita muIOPS pane akasiyana maVM. Kureva kuti, mutoro wakagovaniswa zvakanyanya zvisina kuenzana, mamwe maVM akashanda neavhareji kukosha kwe1000 IOPS+, uye mamwe - aine kukosha kwe64 IOPS. Cisco HyperFlex mune iyi kesi yaitaridzika zvakanyanya kugadzikana, ese 140 maVM akagamuchira avhareji ye600 IOPS kubva kune yekuchengetedza subsystem, ndiko kuti, mutoro pakati pemashini chaiwo wakagoverwa zvakaenzana.
Izvo zvakakosha kuti uzive kuti kusaenzana kwakadai kugovera kweIOPS pamichina chaiyo pamutengesi B yakaonekwa mune yega yega yekuyedzwa.
Mukugadzirwa chaiko, maitiro aya ehurongwa anogona kuve dambudziko hombe kune maneja; kutaura zvazviri, mashini ega ega anotanga kuomesa uye hapana nzira yekudzora maitiro aya. Iyo chete, isina kunyatsobudirira nzira yekuisa chiyero, kana uchishandisa mhinduro kubva kune mutengesi B, ndeye kushandisa imwe kana imwe QoS kana kuenzanisa kuita.
mhedziso
Ngatifungei nezve Cisco Hyperflex ine 140 virtual machines per 1 physical node maringe ne70 or less for other solutions? Kune bhizinesi, izvi zvinoreva kuti kutsigira nhamba imwechete yezvikumbiro paHyperflex, unoda 2 nguva shoma nodes pane mumakwikwi ekugadzirisa, i.e. iyo yekupedzisira system ichave yakachipa zvakanyanya. Kana isu tikawedzera pano mwero we automation wese mashandiro ekuchengetedza network, maseva uye chengetedzo chikuva HX Data Platform, zvinova pachena kuti sei Cisco Hyperflex mhinduro dziri kukurumidza kuwana mukurumbira mumusika.
Pakazere, ESG Labs yakasimbisa kuti Cisco HyperFlex Hybrid HX 3.0 inoburitsa nekukurumidza uye kunoenderana kuita kupfuura mamwe mhinduro dzakafanana.
Panguva imwecheteyo, HyperFlex hybrid masumbu aive zvakare pamberi pevakwikwidzi maererano neIOPS neLatency. Zvakaenzana zvakakosha, kuita kweHyperFlex kwakawanikwa nemutoro wakagovaniswa zvakanyanya pane yese chengetedzo.
Rega tikuyeuchidze kuti iwe unogona kuona iyo Cisco Hyperflex mhinduro uye simbisa kugona kwayo izvozvi. Iyo sisitimu iripo yekuratidzira kune wese munhu:
