Siqhubeka nochungechunge lwezihloko mayelana ne-Cisco Hyperflex. Kulokhu sizokwethula ngomsebenzi we-Cisco Hyperflex ngaphansi kwe-Oracle egcwele kakhulu kanye ne-Microsoft SQL DBMSs, futhi siqhathanise imiphumela etholwe nezixazululo zokuncintisana.
Ngaphezu kwalokho, siyaqhubeka nokubonisa amakhono we-Hyperflex ezifundeni zezwe lethu futhi siyajabula ukukumema ukuba uhlanganyele emibukisweni elandelayo yesixazululo, kulokhu okuzobanjelwa emadolobheni aseMoscow naseKrasnodar.

Kuze kube muva nje, izixazululo ze-hyperconverged zazingezona isixazululo esifanelekile kakhulu se-DBMS, ikakhulukazi lezo ezinomthwalo omkhulu. Kodwa-ke, ngenxa yokusetshenziswa kwendwangu ye-UCS njengengxenyekazi ye-hardware ye-Cisco Hyperflex, eye yafakazela ukwethembeka nokusebenza kwayo eminyakeni eyi-10, lesi simo sesivele sishintshile.

Isingeniso
Njengamanje, kunezindlela ezimbili zokuhlela izixazululo ze-hyperconverged. Indlela yokuqala isuselwe kuzixazululo ezichazwe ngeSoftware, ezilethwa njengesoftware, futhi amakhasimende azikhethela okokusebenza. Indlela yesibili isekelwe kuzixazululo ze-turnkey, okungukuthi, eziqukethe isofthiwe, i-hardware, nokusekelwa kwezobuchwepheshe. Kwa-Cisco, silandela indlela yesibili futhi siletha izixazululo ezenziwe ngomumo kumakhasimende ethu, njengoba lokhu kuwukuphela kwendlela yokuqinisekisa ukuziphatha kwesistimu okuzinzile, ukusekelwa kwezobuchwepheshe okuphezulu okuvela kumkhiqizi oyedwa, nokusebenza okuphezulu.
Ukusebenza okuphezulu kwesistimu okungenye yezinto ezibalulekile lapho unquma ukuthi umkhiqizo othile uzowusebenzisa yini emisebenzini ebalulekile yenjongo.
Namuhla, izinhlangano zivame ukubeka imisebenzi ebaluleke kakhulu ezixazululweni zezakhiwo zezigaba ezintathu zakudala (isitoreji > inethiwekhi yesitoreji > amaseva). Ngesikhathi esifanayo, izinhlangano eziningi zilwela ukwenza lula nokunciphisa izindleko zengqalasizinda yazo ye-IT ngaphandle kokunciphisa ukuzinza nokusebenza kwayo. Ngalesi sizathu, amakhasimende amaningi ngokwengeziwe anaka izixazululo ze-hyperconverged.
Kulesi sihloko, sizokhuluma ngokuhlolwa kwakamuva (ngoFebhuwari 2019) okwenziwe ilabhorethri ye-ESG ezimele (Iqembu le-Enterprise Strategy). Ngesikhathi sokuhlolwa, ukusebenza kwe-Oracle elayishwe kakhulu kanye ne-MS SQL DBMSs (ukuhlolwa kwe-OLTP) kwalingiswa, okungenye yezingxenye ezibaluleke kakhulu zengqalasizinda ye-IT endaweni ekhiqizayo yangempela.
Lo mthwalo wenziwa ngezixazululo ezintathu: I-Cisco Hyperflex, kanye nezixazululo ezimbili ezichazwe ngesofthiwe ezifakwe kumaseva afanayo asetshenziswa ku-Hyperflex, okungukuthi, kumaseva e-Cisco UCS.
Hlola izilungiselelo
Uhlelo lomthengisi A alusebenzisi inqolobane ngoba ukulungiselelwa kwenqolobane akusekelwe umthuthukisi wesixazululo. Ngenxa yalesi sizathu, amadiski asetshenziselwa ukugcina umthamo owengeziwe.
Indlela yokuhlola
Ukuhlolwa kwe-OLTP kwenziwa ngemishini emine ebonakalayo kanye nesethi yedatha yokusebenza engu-3,2 TB. Ngaphambi kokuhlolwa ngakunye, i-VM ngayinye yayigcwaliswe ngedatha erekhodiwe kusetshenziswa ithuluzi lokuhlola. Lokhu kuqinisekisa ukuthi ukuhlolwa kufunda idatha "yangempela" futhi kuyibhale kumabhulokhi akhona, kunokumane ubuyisele amabhlogo angenalutho noma amanani angenalutho ngokuqondile esuka kumemori. Lokhu kwenzeka lapho idatha ingagcwaliswanga, ngakho-ke bekubalulekile ukuqinisekisa ukuthi ukuhlolwa kubonisa ngokunembile ukuthi idatha ifundwe futhi yabhalwa kanjani ngaphakathi kwendawo yohlelo lokusebenza. Le khithi enkulu yomsebenzi ithathe isikhathi eside ukuqedwa, kodwa ngokubona kwethu, iwutshalomali olufanele lwesikhathi njengoba inikeza idatha yokusebenza enembe kakhudlwana.
Ukuhlola kwenziwe kusetshenziswa ithuluzi le-HCI Bench (kusekelwe ku-Oracle Vdbench) kanye namaphrofayela e-I/O aklanyelwe ukulingisa imithwalo yemisebenzi eyinkimbinkimbi ye-OLTP ebucayi kusetshenziswa i-Oracle ne-SQL Server backends. Osayizi bebhulokhi babelwa ngokuya ngezinhlelo zokusebenza ezilingisiwe ezinokufinyelela kwedatha okungahleliwe okungu-100% (okungahleliwe okugcwele).
Umsebenzi we-Oracle Database
Olokuqala kwakuwukuhlolwa kwe-OLTP okuklanyelwe ukulingisa indawo ye-Oracle. I-Vdbench isetshenziselwe ukudala umthwalo wokusebenza ngezilinganiso ezihlukene zokufunda/zokubhala. Ukuhlolwa kwenziwa emishinini emine ebonakalayo. Ngesikhathi sokuhlolwa kwamahora amane, i-HyperFlex ikwazile ukuzuza ngaphezu kwe-420 IOPS nge-latency yama-millisecond angu-000 kuphela. Izixazululo zesofthiwe A no-B zikwazile kuphela ukukhombisa 4.4 kanye 238 IOPS, ngokulandelana.
Amazinga okubambezeleka ayefana ngokulinganayo kuwo wonke amasistimu, ngaphandle kwe-latency yokubhala ye-Vendor B, elinganiselwa ku-26,49 ms, enokufundwa okuhle kakhulu kwe-2,9 ms. Ukuminyanisa nokukhishwa bekusebenza kuwo wonke amasistimu.
Umsebenzi we-Microsoft SQL Server
Okulandelayo, sibheke umthwalo we-OLTP oklanyelwe ukulingisa i-DBMS ye-Microsoft SQL Server.
Njengomphumela walokhu kuhlolwa, iqoqo le-Cisco HyperFlex lisebenze kahle kakhulu ngaphezu kokubili izimbangi A no-B cishe izikhathi ezimbili. 490 IOPS ye-Cisco iqhathaniswa no-000 kanye ne-200 yabakhiqizi A no-B.
Umphumela we-latency ku-Cisco HyperFlex awuzange uhluke kakhulu ekuhlolweni kwe-Oracle, okungukuthi, wawusezingeni elihle le-4,4 ms. Ngesikhathi esifanayo, abakhiqizi A no-B babonise imiphumela emibi kakhulu kunokuhlolwa kwe-Oracle. Okuwukuphela kwesici esihle sesixazululo sokuncintisana B ukubambezeleka kokufunda okuphansi okungaguquki kwe-2,9 ms; kuzo zonke ezinye izinkomba, i-Hyperflex yayiphambili kabili noma ngaphezulu kunezixazululo zokuncintisana.
okutholakele
Ukuhlola okwenziwa ilabhorethri ye-ESG ezimele akuphindanga kwaqinisekisa kuphela izinga elihloniphekile lokusebenza kwesixazululo se-Cisco Hyperflex, kodwa futhi kwafakazela ukuthi amasistimu ahlanganisiwe asevele elungele ukusetshenziswa kabanzi emisebenzini ebaluleke kakhulu yemishini.
Amasistimu we-Hyperconverged sekuyisikhathi eside ebhekwa njengefaneleka kangcono imithwalo yemisebenzi engabalulekile. Ngo-2016, i-ESG yenza ucwaningo phakathi kwezinkampani ezinkulu. Babuzwa ukuthi kungani bekhethe ingqalasizinda yendabuko kunengqalasizinda ehlanganisiwe. U-54% wabaphenduli uphendule ngokuthi isizathu siwukukhiqiza.
Ngokushesha phambili ku-2018. Isithombe sishintshile: inhlolovo ye-ESG ephindayo ithole kuphela u-24% wabaphenduli abasakholelwa ukuthi izindlela zendabuko zisangcono ngokusebenza.
Lapho ukuvela kobuchwepheshe kushintsha imibandela yesinqumo semboni, kuvame ukuba khona ukungafani phakathi kwalokho amakhasimende akufunayo nalokho angakuthola. Abakhiqizi abangakwazi ukubona ukuthi yini engekho futhi bagcwalise leso sikhala banenzuzo. I-Cisco iletha isisombululo se-hyperconverged esiletha ubulula, ukuphumelela kwezindleko, nokusebenza okungaguquki okudingwa ngamakhasimende kumthwalo obalulekile womsebenzi.
I-Cisco iqhubekela phambili kancane kancane emkhakheni wezinhlelo ze-hyperconverged, eziqinisekiswa hhayi kuphela izici ezinhle kakhulu zesisombululo se-Cisco Hyperflex, kodwa futhi nokuba khona kwayo emakethe. Ngakho-ke, ekwindla ka-2018, uCisco wayefaneleka ukungena eqenjini labaholi emakethe ye-HCI ngokusho kukaGartner.
Kakade manje ungaqiniseka ukuthi i-Hyperflex iyisixazululo esihle kakhulu semisebenzi yebhizinisi eyinkimbinkimbi futhi edinga kakhulu ngokuvakashela imiboniso yethu, ezobanjelwa emadolobheni aseMoscow naseKrasnodar.
