Siyaqhubeka nokukwethula ohlelweni lwe-Cisco HyperFlex hyperconverged.
Ngo-Ephreli 2019, iCisco isiphinde yenza uchungechunge lwemiboniso yesixazululo esisha se-hyperconverged Cisco HyperFlex ezifundeni zaseRussia naseKazakhstan. Ungabhalisela umboniso usebenzisa ifomu lempendulo ngokulandela isixhumanisi. Sijoyine!
Phambilini sishicilele indatshana emayelana nokuhlolwa komthwalo okwenziwe yi-ESG Lab ezimele ngo-2017. Ngo-2018, ukusebenza kwesixazululo se-Cisco HyperFlex (inguqulo ye-HX 3.0) kuthuthuke kakhulu. Ngaphezu kwalokho, izixazululo zokuncintisana nazo ziyaqhubeka nokuba ngcono. Yingakho sishicilela inguqulo entsha, yakamuva kakhulu yezilinganiso zokucindezeleka ze-ESG.
Ehlobo lika-2018, ilabhorethri ye-ESG yaphinda yaqhathanisa neCisco HyperFlex nezimbangi zayo. Ngokucabangela inkambiso yamanje yokusebenzisa izixazululo ezichazwe nge-Software, abakhiqizi bezinkundla ezifanayo nabo bangeziwe ekuhlaziyeni okuqhathanisayo.
Hlola izilungiselelo
Njengengxenye yokuhlola, i-HyperFlex iqhathaniswe nezinhlelo ezimbili ezigcwele ze-hyperconverged ezifakwe kumaseva ajwayelekile we-x86, kanye nesoftware eyodwa nesixazululo sehadiwe. Ukuhlola kwenziwa kusetshenziswa isofthiwe evamile yezinhlelo ezihlanganisiwe ze-hyperconverged - i-HCIBench, esebenzisa ithuluzi le-Oracle Vdbench futhi izenzele inqubo yokuhlola. Ikakhulukazi, i-HCIBench idala ngokuzenzakalelayo imishini ebonakalayo, ixhumanise umthwalo phakathi kwayo futhi ikhiqize imibiko elula neqondakalayo.
Imishini ebonakalayo engu-140 yakhiwe iqoqo ngalinye (35 inodi yeqoqo ngalinye). Umshini ngamunye obonakalayo usebenzise ama-vCPU angu-4, 4 GB RAM. Idiski ye-VM yendawo ibingu-16 GB futhi idiski eyengeziwe ingu-40 GB.
Ukulungiselelwa kweqoqo okulandelayo kubambe iqhaza ekuhlolweni:
- iqoqo lamanodi amane e-Cisco HyperFlex 220C 1 x 400 GB SSD yenqolobane kanye ne-6 x 1.2 TB SAS HDD yedatha;
- esiqhudelana naye Umthengisi Iqoqo lamanodi amane 2 x 400 GB SSD yenqolobane kanye ne-4 x 1 TB SATA HDD yedatha;
- esiqhudelana naye Umthengisi B iqoqo lamanodi amane 2 x 400 GB SSD yenqolobane kanye ne-12 x 1.2 TB SAS HDD yedatha;
- esiqhudelana naye Iqoqo Lomthengisi C lamanodi amane 4 x 480 GB SSD wenqolobane kanye no-12 x 900 GB SAS HDD wedatha.
Amaphrosesa kanye ne-RAM yazo zonke izixazululo zazifana.
Hlola inombolo yemishini ebonakalayo
Ukuhlola kuqale ngomthwalo womsebenzi oklanyelwe ukulingisa ukuhlolwa okujwayelekile kwe-OLTP: funda/bhala (RW) 70%/30%, 100% FullRandom enomgomo ongu-800 IOPS ngomshini owodwa (VM). Ukuhlolwa kwenziwa kuma-VM angu-140 kuqoqo ngalinye amahora amathathu kuya kwamane. Umgomo wokuhlolwa uwukugcina ukubambezeleka kokubhala kuma-VM amaningi ngangokunokwenzeka kuye kuma-millisecond angu-5 noma ngaphansi.
Njengomphumela wokuhlolwa (bona igrafu ngezansi), i-HyperFlex ukuphela kweplatifomu eqede lokhu kuhlolwa ngama-VM okuqala angu-140 kanye nokubambezeleka okungaphansi kuka-5 ms (4,95 ms). Kuqoqo ngalinye kwamanye, ukuhlolwa kwaqalwa kabusha ukuze kulungiswe ngokulinga inani lama-VM ekubambeni okuqondisiwe okungu-5 ms ngokuphindaphindiwe okuningi.
Umthengisi A uphathe ngempumelelo ama-VM angu-70 ngesilinganiso sesikhathi sokuphendula esingu-4,65 ms.
Umthengisi B uzuze ukubambezeleka okudingekayo okungu-5,37 ms. kuphela ngama-VM angama-36.
Umthengisi C ukwazile ukuphatha imishini ebonakalayo engu-48 enesikhathi sokuphendula esingu-5,02 ms
I-SQL Server Emulation Yokulayisha
Okulandelayo, i-ESG Lab ilingise umthwalo we-SQL Server. Ukuhlolwa kusebenzise osayizi abahlukene bebhulokhi kanye nezilinganiso zokufunda/zokubhala. Ukuhlolwa kuphinde kwenziwa emishinini eyi-virtual engu-140.
Njengoba kukhonjisiwe esithombeni esingezansi, iqoqo le-Cisco HyperFlex liphumelele ngaphezu kwabathengisi u-A no-B ku-IOPS cishe ngokuphindwe kabili, kanye nomthengisi C izikhathi ezingaphezu kweziyisihlanu. Isikhathi sokuphendula esimaphakathi se-Cisco HyperFlex sasingu-8,2 ms. Uma kuqhathaniswa, isilinganiso sesikhathi sokuphendula soMdayisi A sasingu-30,6 ms, kuMthengisi B sasingu-12,8 ms, futhi kuMdayisi C sasingu-10,33 ms.
Ukuqaphela okuthakazelisayo kwenziwa phakathi nazo zonke izivivinyo. Umthengisi B ubonise ukuhluka okukhulu ekusebenzeni okumaphakathi ku-IOPS kuma-VM ahlukene. Okungukuthi, umthwalo usatshalaliswe ngokungalingani ngokwedlulele, amanye ama-VM asebenze ngenani elimaphakathi lika-1000 IOPS+, kanti amanye - anenani lama-64 IOPS. I-Cisco HyperFlex kuleli cala ibukeka izinzile kakhulu, wonke ama-VM angu-140 athola isilinganiso sama-IOPS angu-600 kusuka kusistimu engaphansi yokugcina, okungukuthi, umthwalo phakathi kwemishini ebonakalayo yasakazwa ngokulinganayo kakhulu.
Kubalulekile ukuqaphela ukuthi ukusatshalaliswa okungalingani okunjalo kwe-IOPS kuyo yonke imishini ebonakalayo kumthengisi B kwabonwa ekuphindaphindweni ngakunye kokuhlolwa.
Ekukhiqizeni kwangempela, lokhu kuziphatha kwesistimu kungaba yinkinga enkulu kubaphathi; empeleni, imishini yomuntu ngamunye iqala ukuba yiqhwa futhi ayikho indlela yokulawula le nqubo. Indlela kuphela, engaphumeleli kakhulu yokulayisha ibhalansi, lapho usebenzisa isisombululo esivela kumthengisi B, ukusebenzisa eyodwa noma enye i-QoS noma ukulinganisa ukuqaliswa.
isiphetho
Ake sicabange ngalokho iCisco Hyperflex inemishini ebonakalayo engu-140 ngenodi eyodwa yomzimba uma iqhathaniswa nama-1 noma ngaphansi kwezinye izixazululo? Ngebhizinisi, lokhu kusho ukuthi ukusekela inombolo efanayo yezicelo ku-Hyperflex, udinga izikhathi ezingu-70 ezimbalwa ze-node kunezixazululo zokuncintisana, i.e. uhlelo lokugcina luzobiza kakhulu. Uma sengeza lapha izinga lokuzenzakalela kwayo yonke imisebenzi yokugcina inethiwekhi, amaseva kanye nesiteji sokugcina i-HX Data Platform, kuyacaca ukuthi kungani izixazululo ze-Cisco Hyperflex zithola ngokushesha ukuthandwa emakethe.
Sekukonke, i-ESG Labs ikuqinisekisile ukuthi i-Cisco HyperFlex Hybrid HX 3.0 iletha ukusebenza okusheshayo nokungaguquguquki kunezinye izixazululo ezifanayo.
Ngasikhathi sinye, amaqoqo e-HyperFlex hybrid nawo abengaphambi kwezimbangi ngokuya nge-IOPS neLatency. Okubaluleke ngokufanayo, ukusebenza kwe-HyperFlex kwafinyelelwa ngomthwalo owasatshalaliswe kahle kakhulu kuso sonke isitoreji.
Ake sikukhumbuze ukuthi ungabona isisombululo se-Cisco Hyperflex futhi uqinisekise amakhono aso njengamanje. Uhlelo luyatholakala ukuze luboniswe kuwo wonke umuntu:
