Koj Puas Paub Cov Ntaub Ntawv Ua Ntaub Ntawv?
Cov chaw ceev ntaub ntawv tseem ceeb rau peb lub neej thiab haujlwm. Txawm li cas los xij, cov ntaub ntawv qhia txog kev ua haujlwm, cov neeg tsim khoom siv teeb meem nrog kev xav siv ntau cov cuab yeej los tswj hwm cov ntaub ntawv chaw tswj, xws li kev muab khoom, kev tswj thiab kev tswj xyuas cov neeg ua haujlwm, uas yog qhov nyuaj, kim, kev ua haujlwm thiab kev ua haujlwm. Puas muaj ib txoj hauv kev zoo los daws cov teeb meem no thiab txhim kho cov ntaub ntawv chaw? Cov lus teb yog kev ua lag luam. Lub chaw nruab nrab ntawm cov ntaub ntawv yog xav tias yog yav tom ntej ntawm cov ntaub ntawv chaw, uas yog hu ua virtual data center.
Ib qho chaw muab cov ntaub ntawv yog ua los ntawm kev ntxiv cov kev laij leb, ntau qhov chaw thiab ntau dua kev sib tham, hos ib qhov chaw khaws ntaub ntawv yog qhov chaw siv cov ntaub ntawv uas siv cov kev siv virtualization uas faib cov tib neeg lub cev rau hauv ntau lub operating systems thiab daim ntaub ntawv, raws li cov cav ntoo (VMs). Hauv lwm cov lus, hauv cov ntaub ntawv xov xwm hauv cov ntaub ntawv txhua qhov kev lag luam yog virtualized thiab kev tswj ntawm cov cuab yeej kho vajtse yog siv los ntawm kev txawj ntse ntse nruab. Qhov no yog qhov sib txawv ntawm qhov sib txawv ntawm cov ntaub ntawv tsom thiab cov ntaub ntawv virtual nrog rau ib qho ntawm qhov zoo tshaj plaws ntawm cov ntaub ntawv ntawm cov ntaub ntawv virtual.
Raws li tau hais tias cov ntaub ntawv siv virtualization yog xam raws li cov qauv ntawm cov ntaub ntawv yav tom ntej. Tab sis dab tsi ua tau cov ntaub ntawv virtual ntaub ntawv muab? Dab tsi yog qhov zoo ntawm virtual ntaub ntawv chaw piv nrog cov ib txwm? Lub peev xwm tseem ceeb thiab cov txiaj ntsim ntawm cov ntaub ntawv hauv virtual data yog qhia nyob rau hauv tshooj no.
Kev Txuag Txuag: nws paub tias qhov cuab yeej kho mob feem ntau yog qhov siab tshaj nyob rau hauv cov ntaub ntawv xov xwm. Kev txhim kho ntawm cov ntaub ntawv sau nruab nrab yog nyob ntawm kev kho vajtse thiab kev cia khoom. Tsuas yog tus nqi kho vajtse, kev tswj thiab kev kho ntawm qhov kho vajtse no yog nyob ntawm seb qhov haujlwm ua haujlwm ntawm qhov kev siv nyiaj yuav zoo dua li ntawm kev kho vajtse. Yog li, nrog cov ntaub ntawv virtual, qhov nqi yuav raug txiav ntau.
Yooj Yim Kev Tswj thiab Kev Txij Nkawm: hauv cov ntaub ntawv xov xwm, cov khoom xws li cov cua kub cev, cov neeg ua hauj lwm hauv lub cev, cov ntaub ntawv thaub qab thiab kev soj ntsuam yuav tsum raug xam tias yog. Thiab ntau ntawm kev ua hauj lwm thiab nyiaj tau ploj mus rau hauv feem ntawm kev tswj xyuas txhua hnub thiab kev saib xyuas. Virtualize cov servers siv tsawg lub cev kho vajtse, tsawg cua sov yuav tsum generated. Cov kauj ruam uas thaub qab yuav yooj yim dua hauv virtual data center ua los ntawm software. Ob qho tag nrho thaub qab thiab snapshots ntawm virtual server thiab virtual cav yuav ua tau thiab cov VMs yuav tsiv ntawm ib tug neeg rau zaub mov mus rau lwm tus yooj yim thiab sai dua. Raws li kev soj ntsuam, nrog cov ntaub ntawv virtual qhov chaw twv xeem yuav raug cais tawm ntawm cov neeg siv thaum uas ua rau lawv nyob online. Thaum twg koj twb ua tiav koj cov dej num, muab nws tso ua neej.
Fav Rov Qab: Yog hais tias lub cev neeg lub cev tuag, lub redeployment yuav xav tau ntau lub sijhawm. Txawm li cas los xij, nrog kev ua lag luam, lub redeploy tuaj yeem tshwm sim nyob rau hauv feeb nrog ob peb lo lus. Teeb meem puas tsuaj, yog tias qhov chaw khaws ntaub ntawv muaj virtualized, nrog cov ntaub ntawv tshaj tawm ntawm koj cov VMs, koj tuaj yeem ceev nrooj rov qab thiab khiav. Nrog cov ntaub ntawv virtual, ib lub party ntawm teeb meem mus deb.
Hla mus rau Huab Tais: nrog cov cav ntoo, koj yuav txav ze rau kev lom huab. Koj tuaj yeem mus txog qhov chaw uas koj tuaj yeem xa VMs rau thiab los ntawm koj qhov chaw muab kev pabcuam los tsim kev tsim kho huab-muaj zog. Tab sis dhau qhov tseeb cov cav tov virtual, tias virtualization tshuab tau koj los ze rau huab-based mindset, ua tus migration tag nrho cov yooj yim dua.
Cov txiaj ntsig zoo no yog lub hauv paus tseem ceeb tshaj plaws uas tsav cov qauv ntawm cov chaw khaws ntaub ntawv rau virtualization. Txawm li cas los xij, yuav tsum tau siv tag nrho cov txiaj ntsig ntawm qhov chaw khaws ntaub ntawv xov xwm, muaj ntau yam kev cov nyom ua ntej, xws li kev ruaj ntseg, kev faib khoom, kev tsim cov kev nqis peev ntxiv rau hauv cov kev lag luam. Ib qho ntawm cov kev cov nyom tshaj plaws yog bandwidth. Raws li tau hais, virtual data center yog kaw los ntawm ntse nruab software, uas xav tau kev pab txhawb nqa ntawm kev siv bandwidth. Tam sim no 10 Gigabit Ethernet (GbE) yog tam sim no tau txais tus saws uas yuav yog ib qho kev xaiv zoo rau kev siv cov khoom siv network. Txawm li cas los, tej zaum yuav muaj blocks hauv kev mus rau virtual data center nrog 10GbE. Los ua kom pom tseeb cov txiaj ntsig ntawm qhov chaw ua haujlwm, qhov kev siv rau 40/100 GbE raug pom zoo raws li thawj kauj ruam rau virtualization. Tam sim no, ntau cov neeg muag khoom muab cov kev daws teeb meem rau 40/100GbE. Tus nqi ntawm 40/100GbE yog txo qis dua rau yav tom ntej. Qhov nce traction ntawm 40 / 100GbE tau coj mus rau nws qhov kev xyaum zoo tshaj plaws raws li tus txheej txheem rau cov cim ntxiv ntawm high-bandwidth virtualized daim ntawv thov.
Qhov sib txawv ntawm cov ntaub ntawv center virtualization yog tseeb nrog cov kev pabcuam zoo thiab tej daim ntawv thov uas cov ntaub ntawv khaws xov xwm tuaj yeem coj tuaj rau peb. 40 / 100GbE tsuas yog thawj kauj ruam ntawm txoj kev taug mus rau virtual cov ntaub ntawv chaw, teeb meem xws li kev ruaj ntseg thiab cov chaw muab kev pabcuam puas muaj mus ua txhaum.
