Kho vajtse virtualization. Tus thawj acquaintance

Muaj ntau cov kws txawj nyob rau hauv lub tshav pob ntawm nws tau hais ntau ntau zaus ntsib nrog ib lub sij hawm xws li "kev kho vajtse virtualization". Thiab nws yog tsis muaj coincidence, vim hais tias ntawm no peb muaj mus nrog ib tug qhov build-up ntawm lub hwj chim khoom. Yuav ua li cas yog virtualization? Yog dab tsi? Yuav ua li cas yog nws cov ntsiab zoo thiab qhov tsis zoo? Wb sim kom paub.

Lub sij hawm "virtualization" yog hais txog cov txheej txheem uas cuag tau ib tug txheej ntawm zoo-txhais ntaub ntawv cov ntaub ntawv. Raws li ib tug tshwm sim, muaj zoo tsis pib system configuration.

Rau ib dlaim phaj xaav yuav tsum tau muab sau tseg tias tus txheej txheem yog muab faib ua ob cov lus qhia, yog ib tus uas - nyob rau hauv lub operating system theem virtualization (kev pab cuam), thiab lub thib ob - hardware virtualization (neeg rau zaub mov).

Kom txog rau thaum nyuam qhuav, virtualization software tau ntau nrov, raws li nws tso cai rau kom muab tau hauj dlaws. Txawm li cas los, nyob rau ntawm no taw tes rau hauv lub sij hawm virtualization yug (hardware) yog npaum li cas nce, uas nws sai sai hloov los ntawm ib tug ua qhov chaw ntawm nws cov thawj ntawm. Ib tug decisive luag hauj lwm yog ua si no los ntawm kev txhim kho system kev kawm thiab muaj peev xwm.

Kho vajtse virtualization. zoo

1. Txaus yooj yim txoj kev loj hlob platform virtualization (nyob rau hauv sib piv mus rau txoj kev loj hlob ntawm ib tug virtualization software). Qhov no yuav qhia ib txog kev kom zoo dua nyob rau hauv lub sij hawm los tsim tshiab platforms thiab thiaj li ua hauj lwm rau cov nqi.

2. Cov simultaneous thiab ywj siab launching ib tug khub ntawm virtual platforms (thaum tswj tau siv lawv txhua txhua tus zuj zus), hais tias, raws li, qhov kev kawm ntawm lub cev.

3. Cov tau optimization.

4. simplifying infrastructure tswj servers.

Kho vajtse virtualization. shortcomings

1. High yuav tsum rau kho vajtse kev daws teeb meem (servers).

2. High nqi ntawm kev siv lub tshuab.

Muaj ntau ntau ntau hom kev neeg rau zaub mov virtualization. Tus thawj hom - yog ib tug consolidation (zajlus kom qab ntau virtual servers rau ib tug hluas lub cev neeg rau zaub mov), lub thib ob hom yog ib tug grouping ntawm lub cev cov cav tov nyob rau hauv ib zaug xwb (zajlus kom), uas nws lub hom phiaj - kov ib tug yooj yim ua hauj lwm.

nyob rau hauv kev xyaum pub ob peb ua ke ntawm ob hom. Yuav kom siv tau ib yam ntawm cov no tsuas tau yog hais tias tus duas paub kho vajtse (CPU uas txhawb nqa kev kho vajtse virtualization technology).

Thaum no tus taw tes nyob rau hauv lub sij hawm yog feem ntau variants ntawm kev tsim kho technology raws li AMD processors thiab Intel. Yuav kom nrhiav tau tawm raws nraim li uas processor qauv txhawb neeg rau zaub mov virtualization, koj yuav tsum mus rau lub chaw tsim tshuaj paus lub website thiab saib tus ntaus ntawv.

Nyob rau hauv kev, hardware virtualization - qhov no yog ib tug zoo heev thiab yooj yim technology lug txhim khu kev productivity. Yuav kom nkag siab txog cov uas duav txhua yam ntawm nws lub hwj chim, nws yog txaus hais tias cov technology siv nyob rau hauv industrial systems thiab kev kho mob pab kiag li lawm, tsis hais cov ib txwm loj tuam txhab uas muag nrog ib tug loj fleet ntawm kev pab kiag li lawm, xav mus ntxiv ntsaub lawv lawm kev pab.
