Cong Wang, i cili shoq\u00ebron n\u00ebn-sistemin e menaxhimit t\u00eb trafikut (TC, Traffic Control) n\u00eb kernelin Linux dhe zhvillon projektin Multikernel, ka paraqitur n\u00eb list\u00ebn e zhvilluesve t\u00eb kernelit Linux nj\u00eb sistem t\u00eb ri skedar\u00ebsh DAXFS. DAXFS p\u00ebrdor memorin\u00eb e operativ\u00ebs p\u00ebr ruajtjen e t\u00eb dh\u00ebnave, punon n\u00eb modalitetin vet\u00ebm p\u00ebr lexim dhe i ngjan funksionalisht sistemeve t\u00eb skedar\u00ebve t\u00eb kufizuara ramfs dhe tmpfs.

Tipari ky\u00e7 i FS-s\u00eb s\u00eb re \u00ebsht\u00eb angazhimi i n\u00ebn-sistemit DAX (Access Direkt) p\u00ebr t\u00eb punuar p\u00ebrmes caches s\u00eb faqeve dhe p\u00ebr qasje t\u00eb drejtp\u00ebrdrejt\u00eb n\u00eb memorien fizike t\u00eb ndar\u00eb.
