tso tawm ntawm pawg ntaub ntawv system , feem ntau (~ 60%) Linux pawg muaj kaum tawm txhiab tus nodes. Scalability nyob rau hauv xws li loj systems yog tiav los ntawm ib tug multi-component architecture. Cov khoom tseem ceeb ntawm Luster yog metadata ua thiab khaws cia servers (MDS), tswj servers (MGS), object storage servers (OSS), object storage (OST, supports run top of ext4 and ZFS) and clients.
ntsiab :
- Persistent Client Cache, uas tso cai rau koj siv cov chaw cia hauv zos, xws li NVMe lossis NVRAM, ua ib feem ntawm lub ntiaj teb FS namespace. Cov neeg siv khoom tuaj yeem cache cov ntaub ntawv cuam tshuam nrog cov ntaub ntawv tsim tshiab lossis cov ntaub ntawv uas twb muaj lawm nyob rau hauv lub zos mounted cache cov ntaub ntawv system (xws li ext4). Thaum tus neeg siv tam sim no tab tom khiav, cov ntaub ntawv no tau ua tiav hauv zos ntawm qhov ceev ntawm FS hauv zos, tab sis yog tias lwm tus neeg siv tau sim hu rau lawv, lawv yuav tau tsiv mus rau lub ntiaj teb FS.
- Hauv routers Tsis siv neeg tshawb pom ntawm txoj hauv kev thaum siv routing raws ntau txoj hauv kev los ntawm kev sib txawv network interfaces (Multi-Rail Routing) thiab nce kev ntseeg tau ntawm kev teeb tsa nrog cov nodes uas muaj ntau lub network interfaces.
- "overstriping" hom, nyob rau hauv uas ib lub khw muag khoom (OST) tuaj yeem muaj ob peb daim ntawv theej ntawm stripe blocks rau ib cov ntaub ntawv, uas tso cai rau ntau tus neeg siv ib txhij ua haujlwm sib sau ua haujlwm rau cov ntaub ntawv yam tsis tau tos lub xauv tso tawm.
- tshwm sim Nws tus kheej txuas cov ntaub ntawv layouts (Self-Extending Layouts), ua kom yooj yim ntawm kev siv PFL (Progressive File Layouts) hom nyob rau hauv heterogeneous cov ntaub ntawv systems. Piv txwv li, thaum cov ntaub ntawv kaw lus suav nrog cov pas dej me me raws li ceev Flash drives thiab cov pas dej loj loj, qhov kev xav tau tso cai rau koj sau ntawv rau ceev ceev ua ntej, thiab tom qab qhov chaw khiav tawm, cia li hloov mus rau qeeb disk pas dej.
