Siyaqhubeka nokuxoxa ngezinto ezintsha zobuchwepheshe ezethulwe engqungqutheleni ye-VMware EMPOWER 2019 e-Lisbon. Izinto zethu ezisetshenziswa esihlokweni sika-Habré:
I-Virtualization yesitoreji ifinyelela ezingeni elisha
Usuku lwesithathu kwa-VMware EMPOWER 2019 lwaqala ngokuhlaziywa kwezinhlelo zenkampani zokuthuthukiswa komkhiqizo we-vSAN nezinye izixazululo zokwenziwa ngokoqobo kwezinhlelo zokugcina idatha. Ikakhulukazi, besikhuluma ngokubuyekeza i-vSAN 6.7 update 3.
I-vSAN iyisitoreji esihlanganisiwe se-vSphere esidizayinelwe ukuthunyelwa kwamafu okuyimfihlo nesesidlangalaleni. Ikuvumela ukuthi ukhiphe kuma-hardware disks futhi usebenze ngamachibi wezinsiza ngaphandle kokukhathazeka ngokuthi idatha yomshini ebonakalayo ikuphi. Ukuqala ngenguqulo ye-vSAN 6.7, abathuthukisi bafundise isistimu ukusebenzisa ingqalasizinda ngendlela ephumelela kakhudlwana - ithuluzi likhulula ngokuzenzakalelayo isikhala, linciphise inani lezindleko zobunikazi besitoreji.
Abamele i-VMware bathi inguqulo entsha ye-vSAN inokusebenza okukhulu kwe-I/O (ngo-20-30%) uma kuqhathaniswa neyandulelayo. Futhi, isistimu ebuyekeziwe yaxazulula ezinye zezinkinga ezihlobene nokufuduka kwe-vMotion, ukuphindaphinda nokusebenza ngezifinyezo. Le misebenzi isizinze kakhulu - manje izimo "zokunamathela" amadiski omshini abonakalayo ngesikhathi sokufuduka kanye nokulahlekelwa izinguquko ngesikhathi sokudala nokususwa kwezifinyezo kuzoba kancane kakhulu. Onjiniyela benkampani bathembisa ukuziqeda ngokuphelele ezibuyekezweni ezilandelayo ze-vSAN 6.7.
Umdondoshiya we-IT futhi usebenzela ukwethula ukusekelwa okugcwele kwengqalasizinda yediski ye-All-NVMe kanye nokwenza i-vSAN isebenze kahle nezinhlaka ze-SSD. Phakathi kwezinto ezibalulekile, izikhulumi zenkampani zigqamise ukukhiqiza okukhulayo nokuvikelwa kwedatha uma kwenzeka ukwehluleka kwezinto zokugcina. Okokuqala, sikhulume ngokwandisa isivinini sokwakhiwa kabusha kwe-array, ukusebenza nge-Redirect-On-Write mechanism, futhi ngokuvamile ukunciphisa inani lemisebenzi yediski phakathi kwemidiya kunethiwekhi. Okuphinde kwashiwo ukutholwa ngokushesha kwedatha phakathi kwama-cluster node nokunciphisa ukubambezeleka.
“I-vSAN iya ngobuhlakani, nemisebenzi eminingi ehlakaniphe kakhulu ehlobene nokunquma indawo yedatha nokuthuthukisa imizila ngesikhathi sokudlulisela. Lezi zici zibalulekile ekusebenzeni kwemisebenzi efana ne-DRS, i-vMotion, njll.
Ngesikhathi esifanayo, amasistimu obuhlakani bokwenziwa asetshenziswa ngenkuthalo emkhiqizweni we-vSAN. Imisebenzi yayo ihlanganisa ukuqapha isimo se-disk subsystems, "ukwelapha" ngokuzenzakalelayo, kanye nokwazisa abaphathi nokudweba imibiko / izincomo.
Mayelana nokutholwa kwedatha
Kwelinye lamaphaneli e-VMware EMPOWER 2019, izikhulumi zixoxe ngokuhlukana ngamakhono e-NSX-T 2.4 ebuyekeziwe, edizayinelwe ukwenziwa kwenethiwekhi nokuhlanganisa amanethiwekhi abonakalayo esikhungo sedatha. Ingxoxo yayimayelana namakhono epulatifomu kumongo wokutholwa kwedatha ephuthumayo (Ukubuyiselwa Kwenhlekelele).
I-VMware isebenza ngenkuthalo kuzixazululo zayo ze-DR endaweni yesayithi eyodwa kanye nezindawo eziningi. Inkampani ikwazile ukucishe ikhiphe izinsiza ezibonakalayo (imishini, amadiski, amanethiwekhi) kusuka kumapulatifomu abonakalayo. Kakade manje i-NSX-T ingasebenza ngamafu amaningi, ama-multi-hypervisor nama-bare-metal node.
Ithuluzi linciphisa isikhathi sokutholwa kwedatha kanye nenani lemisebenzi eyenziwa ngesandla ehlotshaniswa nokulungiswa kabusha kwengqalasizinda (amakheli e-IP, izinqubomgomo zokuphepha, umzila kanye nemingcele yezinsizakalo ezisetshenzisiwe) ngemva kokuthuthela kumishini emisha, lapho izimo eziningi zobuchwepheshe zishintsha.
“Ukubuyisela zonke izilungiselelo mathupha kuthatha isikhathi eside, futhi kunesici somuntu - umlawuli wesistimu angase akhohlwe noma azibe inani lezinyathelo eziyisibopho. Amaphutha anjalo aholela ekuhlulekeni kuyo yonke ingqalasizinda ye-IT noma amasevisi angawodwana. Futhi, isici somuntu sithinta kabi impumelelo yokutholakala kwedatha kanye nesivinini sokuthola kabusha idatha () "
Ngalezi zizathu, i-VMware iwukhuthaza ngenkuthalo umbono wokuhlukaniswa okuncane okunengqondo kwengqalasizinda, ukucula nokuzenzakalelayo kwezinqubo zokubuyisela. Kugcizelelwa ngokukhethekile ukuqaliswa kwezinhlelo zobuhlakani bokwenziwa. Sezivele zivela kuzixazululo ezinkulu ze-IT njenge-VMware NSX Cluster Management, Storage Replication, kanye nokushintsha okubonakalayo kanye namahubhu asekelwe kuphrothokholi ye-Geneve. Eyakamuva ithathe indawo ye-NSX-V VXLAN futhi iyisisekelo okwakhiwa kuso i-NSX-T.
Abamele inkampani bakhulume ngoshintsho olubushelelezi ukusuka ku-VMware NSX-V ukuya ku-NSX-T . Isici esiyinhloko sesixazululo esisha iqiniso lokuthi asiboshelwe ku-vCenter/vSphere, ngakho-ke singasetshenziswa njengesixazululo esizimele sezinhlobo ezahlukene zengqalasizinda.
Sivakashele izitendi zedemo ze-VMware ezikhethekile, lapho sakwazi khona ukuhlola ukusebenza kwemikhiqizo echazwe ngenhla ngokwenza. Kuvele ukuthi naphezu kokusebenza okubanzi, ukuphatha izixazululo ze-SD-WAN ne-NSX-T kulula kakhulu. Sikwazile ukuthola yonke into “ngokuphazima kweso” ngaphandle kosizo lwababonisi.
Kuhle ukuthi i-VMware inaka imisebenzi ehlobene nokuvikeleka kwedatha nokuthola kabusha. Namuhla, njengomthetho, izinhlelo zezinkampani zangaphandle zinesibopho sokuzixazulula, okuholela ezinkingeni zokuhambisana (ikakhulukazi lapho izimo zengqalasizinda zishintsha) kanye nezindleko ezengeziwe ngamakhasimende. Izixazululo ezintsha ze-VMware zizokwandisa ukuzinza kwezinqubo ezenzeka kwingqalasizinda ye-IT.
