U 2018. godini karakteristike rje\u0161enja Cisco HyperFlex (verzija HX 3.0) znatno su pobolj\u0161ane. Osim toga, konkurentska rje\u0161enja tako\u0111er se nastavljaju unapre\u0111ivati. Zbog toga objavljujemo novu, a\u017euriranu verziju usporednih optere\u0107enja testova od ESG-a. <\/p>\n<p>Tijekom ljeta 2018. laboratorija ESG provela je ponovljeno uspore\u0111ivanje Cisco HyperFlex s konkurencijom. Uzimaju\u0107i u obzir modernu tendenciju kori\u0161tenja rje\u0161enja temeljenih na softveru, u usporedni pregled su tako\u0111er dodani proizvo\u0111a\u010di sli\u010dnih platformi. <\/p>\n<h2>Testne konfiguracije<\/h2>\n<p>\nTijekom testiranja HyperFlex je uspore\u0111ivan s dva potpuno softverska hiperkonvergentna sustava, koja se instaliraju na standardne x86 servere, kao i s jednim hardversko-softverskim rje\u0161enjem. Testiranje je provedeno kori\u0161tenjem standardnog softvera za hiperkonvergentne sustave \u2013 HCIBench, koji koristi alat Oracle Vdbench i automatizira proces testiranja. Konkretno, HCIBench automatski stvara virtualne strojeve, koordinira optere\u0107enje me\u0111u njima i generira korisne i razumljive izvje\u0161taje. \u00a0<\/p>\n<p>Stvoreno je 140 virtualnih strojeva na klaster (35 po \u010dvoru klastera). Svaki virtualni stroj koristio je 4 vCPU, 4 GB RAM-a.

Test je proveden na 140 VM-ova u svakom klasteru tijekom tri do \u010detiri sata.

To jest, optere\u0107enje se raspore\u0111ivalo izrazito nejednako, neke VM-ove su radile s prosje\u010dnom vrijedno\u0161\u0107u od 1000 IOPS+, dok su neke radile s vrijedno\u0161\u0107u od 64 IOPS. Cisco HyperFlex se u ovom slu\u010daju pokazao zna\u010dajno stabilnijim, svih 140 VM-ova primilo je u prosjeku 600 IOPS-a od sustava za pohranu podataka, odnosno optere\u0107enje je me\u0111u virtualnim ma\u0161inama bilo vrlo ravnomjerno raspodijeljeno.<\/p>\n<p><img decoding=\"async\" alt=\"Cisco HyperFlex vs. konkurenti: testiranje performansi\" src=\"\/wp-content\/uploads\/2019\/04\/1734468d3c62d2031daa18ae29d03c8e.jpg\" style=\"display:block;margin: 0 auto;\" \/><br \/>\n<br \/>\nVa\u017eno je napomenuti da se ovakva nejednaka raspodjela IOPS-a me\u0111u virtualnim ma\u0161inama kod dobavlja\u010da B primijetila u svakoj iteraciji testiranja. <\/p>\n<p>U stvarnom produtivnom okru\u017eenju, takvo pona\u0161anje sustava mo\u017ee biti veliki problem za administratore, jer pojedine virtualne ma\u0161ine nasumi\u010dno po\u010dinju \u201esmrzavati\u201d i gotovo da ne postoji na\u010din za kontrolu tog procesa.

Ako ovome dodamo i razinu automatizacije svih operacija odr\u017eavanja mre\u017ee, poslu\u017eitelja i platforme za pohranu HX Data Platform, postaje jasno za\u0161to rje\u0161enja Cisco Hyperflex tako brzo stje\u010du popularnost na tr\u017ei\u0161tu. <\/p>\n<p>Sveukupno, ESG laboratorij je potvrdio da hibridni Cisco HyperFlex modeli HX 3.0 pru\u017eaju vi\u0161u i stabilniju izvedbu od drugih sli\u010dnih rje\u0161enja. <\/p>\n<p>Dodatno, hibridni klasteri HyperFlex su nadma\u0161ili konkurente po IOPS i Latency pokazateljima. Jednako va\u017eno je to da je izvedba HyperFlex-a postignuta pri vrlo dobro raspore\u0111enom optere\u0107enju po cijeloj pohrani.<\/p>\n<p>Podsje\u0107amo, rje\u0161enje Cisco Hyperflex mo\u017eete vidjeti i uvjeriti se u njegove mogu\u0107nosti ve\u0107 sada.
