kutulutsidwa kwa cluster file system , kwambiri (~ 60%) Magulu a Linux okhala ndi ma node masauzande. Scalability pamakina akuluakulu otere amatheka kudzera muzomangamanga zamitundu yambiri. Zigawo zazikulu za Luster ndi ma metadata processing and storage servers (MDS), ma seva otsogolera (MGS), ma seva osungira zinthu (OSS), kusunga zinthu (OST, zothandizira kuthamanga pamwamba pa ext4 ndi ZFS) ndi makasitomala.
waukulu :
- cache yolimbikira yamakasitomala (Persistent Client Cache), kukulolani kugwiritsa ntchito zosungirako zakomweko, monga NVMe kapena NVRAM, monga gawo la FS yapadziko lonse lapansi. Makasitomala amatha kusungitsa deta yolumikizidwa ndi mafayilo omwe angopangidwa kumene kapena omwe alipo kale mu fayilo ya cache yokhazikitsidwa kwanuko (mwachitsanzo ext4). Pamene kasitomala wamakono akugwira ntchito, mafayilowa amasinthidwa kumaloko mofulumira kwa FS yakomweko, koma ngati kasitomala wina ayesa kupeza, amasamutsidwa kupita ku FS yapadziko lonse.
- Mu ma routers Kudzipezera zokha mayendedwe mukamagwiritsa ntchito njira zingapo kudzera pamanetiweki osiyanasiyana (Multi-Rail Routing) ndikuwonjezera kudalirika kwamasinthidwe okhala ndi ma node omwe ali ndi maukonde angapo.
- "Overstriping", momwe sitolo imodzi (OST) imatha kukhala ndi mizere ingapo ya fayilo imodzi, yomwe imalola makasitomala angapo nthawi imodzi kupanga zolembera zophatikizana pafayilo popanda kuyembekezera loko kumasulidwa.
- Zawonekera Mafayilo odzikulitsa okha (Mapangidwe Odzikulitsa), kukulitsa kusinthasintha kwa kugwiritsa ntchito mawonekedwe a PFL (Progressive File Layouts) mumafayilo osiyanasiyana. Mwachitsanzo, pamene fayilo imaphatikizapo maiwe osungiramo ang'onoang'ono otengera ma drive othamanga a Flash ndi ma dziwe akuluakulu a disk, gawo lomwe likufunsidwa limakupatsani mwayi wolembera kusungirako mwachangu, ndipo danga litatha, sinthani mwachangu kumayiwe a disk.
