Timapitiliza nkhani za Cisco Hyperflex. Nthawi ino tikudziwitsani za ntchito ya Cisco Hyperflex pansi pa Oracle yodzaza kwambiri ndi Microsoft SQL DBMSs, ndikufaniziranso zotsatira zomwe zapezedwa ndi mayankho ampikisano.
Kuonjezera apo, tikupitiriza kusonyeza mphamvu za Hyperflex m'madera a dziko lathu ndipo tikukondwera kukuitanani kuti mupite ku ziwonetsero zotsatirazi za yankho, zomwe nthawi ino zidzachitikira m'mizinda ya Moscow ndi Krasnodar.

Mpaka posachedwa, mayankho a hyperconverged sanali njira yabwino kwambiri ya DBMS, makamaka omwe ali ndi katundu wambiri. Komabe, chifukwa cha kugwiritsa ntchito nsalu ya UCS ngati nsanja ya hardware ya Cisco Hyperflex, yomwe yatsimikizira kudalirika kwake ndi ntchito zake zaka 10, izi zasintha kale.
Mukufuna kudziwa zambiri? Ndiye kulandiridwa kwa mphaka.
Mau oyamba
Pakadali pano, pali njira ziwiri zokonzekera mayankho a hyperconverged. Njira yoyamba imachokera ku mapulogalamu opangidwa ndi Mapulogalamu, omwe amaperekedwa ngati mapulogalamu, ndipo makasitomala amasankha zipangizo zawo. Njira yachiwiri idakhazikitsidwa ndi mayankho a turnkey, ndiko kuti, okhala ndi mapulogalamu, ma hardware, ndi chithandizo chaukadaulo. Ku Cisco, timatsatira njira yachiwiri ndikupereka mayankho okonzeka kwa makasitomala athu, popeza iyi ndiyo njira yokhayo yotsimikizira khalidwe lokhazikika la machitidwe, chithandizo chapamwamba chaukadaulo kuchokera kwa wopanga m'modzi, komanso magwiridwe antchito apamwamba.
Ndikuchita bwino kwambiri kwadongosolo komwe ndi chimodzi mwazinthu zofunika kwambiri posankha kugwiritsa ntchito chinthu china pazantchito zofunika kwambiri.
Masiku ano, mabungwe amakonda kuyika ntchito zofunika kwambiri pamayankho azomanga atatu apamwamba (kusungirako> network yosungirako> maseva). Panthawi imodzimodziyo, mabungwe ambiri amayesetsa kufewetsa ndi kuchepetsa mtengo wa zomangamanga zawo za IT popanda kuchepetsa kukhazikika ndi ntchito zake. Pachifukwa ichi, makasitomala ochulukirachulukira akulabadira mayankho a hyperconverged.
M'nkhaniyi, tikambirana za mayeso aposachedwa (February 2019) opangidwa ndi labotale yodziyimira payokha ya ESG (Enterprise Strategy Group). Poyesa, ntchito ya Oracle yodzaza kwambiri ndi MS SQL DBMSs (mayeso a OLTP) idatsatiridwa, yomwe ndi imodzi mwamagawo ofunikira kwambiri a zomangamanga za IT m'malo abwino kwambiri.
Katunduyu adachitidwa panjira zitatu: Cisco Hyperflex, komanso mayankho awiri ofotokozedwa ndi mapulogalamu omwe adayikidwa pamaseva omwewo omwe amagwiritsidwa ntchito mu Hyperflex, ndiko kuti, pa ma seva a Cisco UCS.
Kuyesa masinthidwe
Dongosolo la Vendor A siligwiritsa ntchito cache chifukwa kasinthidwe ka cache sikuthandizidwa ndi woyambitsa yankho. Pachifukwa ichi, ma disks adagwiritsidwa ntchito kusunga mphamvu zambiri.
Njira yoyesera
Mayesero a OLTP anachitidwa ndi makina anayi enieni ndi deta yogwira ntchito ya 3,2 TB. Chiyeso chilichonse chisanachitike, VM iliyonse inali ndi deta yojambulidwa pogwiritsa ntchito chida choyesera. Izi zimatsimikizira kuti mayesowo amawerenga "zenizeni" ndikuzilemba ku midadada yomwe ilipo, m'malo mongobweza midadada yopanda pake kapena zinthu zopanda pake kuchokera pamtima. Izi zimachitika pamene deta ilibe anthu, kotero kunali kofunika kuonetsetsa kuti mayeserowo akuwonetseratu momwe deta inawerengedwa ndi kulembedwa mkati mwa malo ogwiritsira ntchito. Chida chachikulu chogwirira ntchitochi chinatenga nthawi yayitali kuti chimalizike, koma m'malingaliro athu ndikusunga nthawi yoyenera chifukwa chimapereka chidziwitso cholondola kwambiri.
Kuyesa kunachitika pogwiritsa ntchito chida cha HCI Bench (chochokera pa Oracle Vdbench) ndi mbiri ya I/O yopangidwa kuti itsanzire zovuta zantchito za OLTP zovutirapo pogwiritsa ntchito Oracle ndi SQL Server backends. Miyeso ya block idaperekedwa molingana ndi mapulogalamu omwe adatsatiridwa ndi 100% mwayi wopezeka mwachisawawa (mwachisawawa chonse).
Ntchito ya Oracle Database
Yoyamba inali mayeso a OLTP opangidwa kuti atsanzire chilengedwe cha Oracle. Vdbench idagwiritsidwa ntchito popanga kuchuluka kwa ntchito ndi magawo osiyanasiyana owerengera / kulemba. Kuyesedwa kunachitika pamakina anayi enieni. Pakuyesa kwa maola anayi, HyperFlex inatha kukwaniritsa zoposa 420 IOPS ndi latency ya 000 milliseconds yokha. Mayankho a mapulogalamu A ndi B amatha kusonyeza 4.4 ndi 238 IOPS, motsatira.
Miyezo ya latency inali yofanana pamakina onse, kupatulapo Vendor B's write latency, yomwe inali pafupifupi 26,49 ms, yokhala ndi kuwerenga kwabwino kwambiri kwa 2,9 ms. Kuphatikizika ndi kuchotsera zinali zogwira ntchito pamakina onse.
Ntchito ya Microsoft SQL Server
Kenako, tidayang'ana ntchito ya OLTP yopangidwa kuti itsanzire Microsoft SQL Server DBMS.
Chifukwa cha mayesowa, gulu la Cisco HyperFlex linapambana onse opikisana A ndi B pafupifupi kawiri. 490 IOPS ya Cisco motsutsana ndi 000 ndi 200 kwa opanga A ndi B.
Zotsatira za latency mu Cisco HyperFlex sizinali zosiyana kwambiri ndi mayeso a Oracle, ndiko kuti, zinali pamlingo wabwino wa 4,4 ms. Nthawi yomweyo, opanga A ndi B adawonetsa zotsatira zoyipa kwambiri kuposa mayeso a Oracle. Mbali yokhayo yabwino yothetsera mpikisano B ndiyomwe imakhala yochepa kwambiri yowerengera 2,9 ms; mu zizindikiro zina zonse, Hyperflex inali kawiri kapena kuposerapo patsogolo pa zothetsera mpikisano.
anapezazo
Kuyesa kochitidwa ndi labotale yodziyimira payokha ya ESG sikunangotsimikiziranso kuchuluka kwa magwiridwe antchito a Cisco Hyperflex yankho, komanso kutsimikizira kuti makina ophatikizika ndi okonzeka kale kugwiritsidwa ntchito pofalitsa ntchito zofunika kwambiri.
Machitidwe a Hyperconverged akhala akuwoneka kuti ndi oyenerera ntchito zosafunikira. Mu 2016, ESG idachita kafukufuku pakati pamakampani akuluakulu. Adafunsidwa chifukwa chake amasankha zida zachikhalidwe kuposa zida za hyperconverged. 54% ya omwe adafunsidwa adayankha kuti chifukwa chake ndikuchita bwino.
Mofulumira ku 2018. Chithunzicho chasintha: kafukufuku wobwereza wa ESG adapeza 24% yokha ya omwe adafunsidwa omwe amakhulupirirabe kuti njira zachikhalidwe zikadali zabwinoko potengera magwiridwe antchito.
Chisinthiko chaukadaulo chikasintha zisankho zamakampani, nthawi zambiri pamakhala kusagwirizana pakati pa zomwe makasitomala amafuna ndi zomwe angapeze. Opanga omwe amatha kuwona zomwe zikusoweka ndikudzaza chopandacho ali ndi mwayi. Cisco imapereka yankho la hyperconverged lomwe limapereka kuphweka, kutsika mtengo, komanso kugwira ntchito kosasinthasintha komwe makasitomala amafunikira pazantchito zofunika kwambiri.
Cisco ikupita patsogolo pang'onopang'ono m'munda wa machitidwe a hyperconverged, omwe amatsimikiziridwa osati ndi makhalidwe abwino a Cisco Hyperflex solution, komanso kupezeka kwake pamsika. Chifukwa chake, kumapeto kwa 2018, Cisco adalowa mgulu la atsogoleri pamsika wa HCI malinga ndi Gartner.
Kale tsopano mungakhale otsimikiza kuti Hyperflex ndi njira yabwino yothetsera ntchito zovuta kwambiri komanso zovuta zamabizinesi poyendera ziwonetsero zathu, zomwe zidzachitike m'mizinda ya Moscow ndi Krasnodar.
