Containers, ntim, thiab partitions yog cov ntsiab lus ntawm lub khoos phis tawj tswj cov ntaub ntawv. Nrog rau kev qhia txog APFS (Apple File System) hauv macOS High Sierra, cov khoom no tau coj los ua lub luag haujlwm tshiab hauv macOS operating system.
Cov ntaub ntawv hauv kab lus no siv tshwj xeeb rau Mac khoos phis tawj, tab sis lwm lub tshuab ua haujlwm kuj siv ntim, ntim, thiab muab faib.
kab hauv qab
Cov thawv ntim khoom yog cov qauv tsim ntawm qhov chaw digital uas muaj ib lossis ntau qhov ntim. Thaum tag nrho cov ntim hauv ib lub thawv siv APFS cov ntaub ntawv, cov ntim sib faib cov chaw muaj nyob hauv lub thawv. Lub ntim uas xav tau qhov chaw cia ntxiv tuaj yeem siv qhov chaw dawb los ntawm lwm lub thawv.
Volume vs. Partition
Ib ntim yog qhov chaw khaws cia rau tus kheej uas lub khoos phis tawj nyeem tau. Ntau hom ntim muaj xws li CDs, DVDs, SSDs, thiab hard drives. Thaum lub khoos phis tawj Mac paub txog qhov ntim, nws txuas rau ntawm lub desktop kom koj nkag tau cov ntaub ntawv nws muaj.
ntim tuaj yeem muab faib ua ib lossis ntau qhov sib faib, uas siv qhov chaw ntawm lub hard drive. Lub ntim tuaj yeem hla ntau lub cev discs lossis drives, tab sis ib qho kev faib yog txwv ntau dua. Tsis zoo li cov partitions, ntim tuaj yeem siv qhov chaw dawb los ntawm txhua qhov chaw, uas ua tsis tau ua ntej APFS.
APFS yog qhov ua kom zoo rau qee hom disk, uas yog cov khoom siv hauv xeev (SSDs). Kev kho dua tshiab rau APFS muaj cov txiaj ntsig txwv rau cov khoos phis tawj nrog lub hard disk drive.
Logical Volumes
Ib yam tsis meej ntxiv ntawm ntim, hu ua qhov ntim qhov xav tau, tsis txwv rau tib lub cev tsav. Nws tuaj yeem tsim ntau qhov kev faib tawm thiab lub cev tsav raws li xav tau. Ib qho kev ntim cov logic faib thiab tswj qhov chaw ntawm ib lossis ntau qhov chaw cia khoom. Nws cais cov kev khiav hauj lwm los ntawm cov khoom siv lub cev uas tsim cov khoom nruab nrab.
Piv txwv li, hauv RAID 1 (mirroring), ntau qhov ntim tshwm sim rau OS raws li ib qho kev xav tau. Ob lub hardware controllers thiab software tuaj yeem tsim RAID arrays. Nyob rau hauv ob qho tib si, OS tsis paub txog dab tsi yog lub cev ua rau lub logical ntim. Nws tuaj yeem yog ib tsav, ob tsav, lossis ntau tsav. Tus naj npawb ntawm cov tsav uas ua rau RAID 1 array tuaj yeem hloov pauv raws sijhawm, thiab OS yeej tsis paub txog cov kev hloov pauv no vim nws pom tsuas yog ib qho kev xav tau xwb.
Nrog lub logical ntim, tsis yog tsuas yog lub cev lub cev qauv ntawm lub ntim ntawm OS pom, tab sis tus neeg siv kuj tuaj yeem tswj hwm nws ntawm OS. Qhov kev teeb tsa no tso cai rau cov ntaub ntawv hloov pauv tau yooj yim dua.
Logical Volume Managers (LVMs)
Logical ntim tuaj yeem muaj qhov sib faib nyob ntawm ntau lub cev cia khoom. Logical Volume Managers (LVMs) ua rau cov tshuab no yooj yim siv. Ib qho LVM tswj cov chaw khaws cia, faib cov faib, tsim cov ntim, thiab tswj cov ntim sib cuam tshuam li cas.
Txij li thaum Apple tau tshaj tawm OS X Lion, macOS tau siv LVM system hu ua Core Storage. Nws yog thawj zaug siv los muab tag nrho-disk encryption system siv los ntawm Apple File Vault 2 system. Thaum OS X Mountain Lion raug tso tawm, Core Storage system tau txais lub peev xwm los tswj cov txheej txheem khaws cia uas Apple hu ua Fusion tsav.
