kusunungurwa kwe cluster file system , kazhinji (~60%) Linux masumbu ane makumi ezviuru emanodhi. Scalability pamasisitimu makuru akadaro anowanikwa kuburikidza neakawanda-component architecture. Izvo zvakakosha zveLuster ndeye metadata kugadzirisa uye kuchengetedza maseva (MDS), manejimendi maseva (MGS), chinhu chekuchengetedza maseva (OSS), kuchengetedza chinhu (OST, inotsigira kumhanya pamusoro ext4 neZFS) uye vatengi.
chikuru :
- inorambira mutengi-parutivi cache (Persistent Client Cache), ichikubvumidza kuti ushandise chengetedzo yemunharaunda, seNVMe kana NVRAM, sechikamu chepasi rose FS namespace. Vatengi vanogona cache data yakabatana neachangobva kugadzirwa kana aripo mafaera mune yakamisikidzwa cache faira system (eg ext4). Ipo mutengi aripo ari kushanda, mafaera aya anogadziriswa munharaunda nekumhanya kweFS yemuno, asi kana mumwe mutengi akaedza kuiwana, anobva angoendeswa kuFS yepasirese.
- Mune ma routers kuwanikwa otomatiki kwenzira paunenge uchishandisa nzira dzakati wandei kuburikidza netiweki nzvimbo dzakasiyana (Multi-Rail Routing) uye kuwedzera kuvimbika kwezvigadziriso nemanode ane akawanda network network.
- "overstriping" modhi, umo chitoro chimwe chete (OST) chinogona kuve nemakopi akati wandei emitsara yefaira imwe, iyo inobvumira vatengi vakati wandei panguva imwe chete kuita majoint kunyorera mashandiro kufaira pasina kumirira kukiya kuburitswa.
- Akaonekwa kuzviwedzera mafaera magadzirirwo (Yega-Kuwedzera Magadzirirwo), kuwedzera kuchinjika kwekushandisa iyo PFL (Progressive File Layouts) modhi mune heterogeneous mafaira masisitimu. Semuenzaniso, kana iyo faira system inosanganisira madiki ekuchengetera madziva akavakirwa pakukurumidza Flash drives uye hombe dhisiki madziva, iyo yakarongwa inobvumidza iwe kuti unyore kune yekutsanya storages kutanga, uye mushure mekunge nzvimbo yapera, otomatiki chinja kune inononoka dhisiki madziva.
