Scale - tawm cia yog lub network txuas khaws cia ( NAS ) architecture nyob rau hauv uas tag nrho cov nqi ntawm qhov chaw disk tuaj yeem nthuav dav los ntawm kev sib ntxiv ntawm cov khoom siv hauv cov khoom sib txuas nrog lawv tus kheej cov peev txheej. Hauv ib nplai - tawm system, kho vajtse tshiab tuaj yeem ntxiv thiab teeb tsa raws li qhov xav tau tshwm sim.
Hauv qhov no, dab tsi yog tus yam ntxwv ntawm kev ntsuas tawm NAS?
A: Cov ntaub ntawv kaw lus loj hlob dynamically raws li cov nodes ntxiv rau hauv pawg. B: Txog li plaub lub tshuab tuaj yeem tsim tau thoob plaws pawg. C: Cov kab ke sib txawv ntawm cov ntaub ntawv raug tsim los ntawm txhua qhov hauv pawg. D: Cov ntaub ntawv sib txawv tuaj yeem sib xyaw ntawm txhua qhov hauv ib pawg.
Ib yam li ntawd, qhov txawv ntawm qhov ntsuas thiab ntsuas tawm yog dab tsi? Lub sij hawm scaling li ” txhais tau tias siv ib tus neeg rau zaub mov muaj zog dua los ua cov haujlwm ua haujlwm uas haum rau hauv thaj tsam ntawm server. Scale - tawm yog ib qho qauv sib txawv uas siv ntau lub processors ua ib lub koom haum kom ua lag luam nplai dhau ntawm lub computer muaj peev xwm ntawm ib lub server.
Raws li txoj cai, dab tsi yog qhov tseeb ntawm qhov ntsuas tawm qhov chaw khaws khoom?
Txij li thaum xwb khaws cia rhawv tau ntxiv thaum nthuav dav, nplai -up architectures muab ib tug nqi-zoo muaj peev xwm upgrade. Scale - tawm architectures ntxiv CPU, nco thiab txuas ntxiv thaum nthuav dav lub peev xwm. Qhov no lav tias kev ua haujlwm tsis poob thaum twg kev ntsuas qhov system.
Scale Up Storage yog dab tsi?
Scale - nce yog daim ntawv feem ntau ntawm cov tsoos thaiv thiab cov ntaub ntawv khaws cia platforms. Lub kaw lus muaj ib khub ntawm controllers thiab ntau rhawv ntawm drives. Thaum koj khiav tawm ntawm qhov chaw, koj ntxiv lwm txee ntawm drives. Scale - nce architecture yog txwv rau scalability txwv ntawm lub khaws cia cov tswj.

Dab tsi ntawm algorithms xav kom tus neeg xa khoom thiab tus neeg txais kev sib pauv hloov tus yuam sij zais cia uas siv los xyuas kom meej qhov tsis pub lwm tus paub ntawm cov lus?
Dab tsi ntawm algorithms xav kom tus neeg xa khoom thiab tus neeg txais kev sib pauv pauv tus yuam sij zais cia uas siv los xyuas kom tsis pub leej twg paub cov lus? Kev piav qhia: Symmetrical algorithms siv tib tus yuam sij, tus yuam sij zais cia, los encrypt thiab decrypt cov ntaub ntawv. Tus yuam sij no yuav tsum tau muab qhia ua ntej ua ntej kev sib txuas lus tuaj yeem tshwm sim
Puas txhais tau tias yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas muab cov lus qhia rau kev siv cov khoom?
Kev them nyiaj yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas txiav txim siab seb qhov khoom siv tau li cas
Dab tsi yog cov yam ntxwv ntawm tus neeg siv khoom server network?
Cov yam ntxwv ntawm Client Server Computing Cov neeg siv khoom server suav ua haujlwm nrog lub kaw lus thov thiab teb. Cov neeg siv khoom thiab cov neeg rau zaub mov yuav tsum ua raws li cov txheej txheem sib txuas lus kom lawv tuaj yeem sib cuam tshuam nrog ib leeg. Ib tus neeg rau zaub mov tuaj yeem ua raws li qee tus neeg thov kev thov ntawm ib lub sijhawm
Dab tsi yog qhov sib txawv ntawm qhov ntsuas qhov ntsuas thiab qhov ntsuas thib ob?
Primary index: nyob rau hauv ib tug sequentially order file, qhov Performance index uas nws search key qhia cov sequential order ntawm cov ntaub ntawv. Kuj hu ua clustering index. Secondary index: ib qho Performance index uas nws qhov tseem ceeb tshawb nrhiav qhia qhov kev txiav txim sib txawv ntawm qhov kev txiav txim ntawm cov ntaub ntawv. Kuj hu ua non-clustering index
Dab tsi yog qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas?
Xav txog nws li no: rhiab heev yog ib qho kev ntsuas ntawm qhov hloov pauv ntawm lub koob yees duab qhov chaw saib uas tsim nyog raws li qhov muaj peev xwm tshawb pom, thiab qhov pib yog qhov ntau npaum li cas ntawm cov lus tsa suab yuav tsum tshwm sim txhawm rau txhawm rau ua rau lub tswb
