Organizata Linux Foundation prezantoi numrin e par\u00eb t\u00eb platform\u00ebs s\u00eb hapur p\u00ebr pajisje Flash t\u00eb menaxhuara me program (Software Enabled Flash), e nd\u00ebrtuar mbi kodin e dor\u00ebzuar nga kompania KIOXIA (para rinovimit t\u00eb emrit Toshiba Memory Corporation), ku u shpik memoria Flash n\u00eb vitin 1980. Tekstet origjinale t\u00eb mjetit jan\u00eb shkruar n\u00eb gjuh\u00ebn C dhe shp\u00ebrndahen n\u00ebn licenc\u00ebn BSD. <\/p>\n
Mjeti p\u00ebrfshin nj\u00eb grup patch-e p\u00ebr b\u00ebrtham\u00ebn Linux, nj\u00eb drejtues bllok p\u00ebr pajisjet SEF (Software Enabled Flash), utilitetet p\u00ebr menaxhim nga linja e komandave, drejtuesit SEF t\u00eb parazi\u00e7tuar p\u00ebr QEMU, nj\u00eb bibliotek\u00eb me API p\u00ebr zhvillimin e aplikacioneve, patch-e p\u00ebr nvme-cli dhe FIO, t\u00eb cilat shtojn\u00eb mb\u00ebshtetje p\u00ebr SEF. SDK gjithashtu p\u00ebrfshin nj\u00eb implementim referenc\u00eb t\u00eb nivelit programor FTL (Flash Translation Layer), q\u00eb siguron kthimin e komandave t\u00eb pajisjeve bllok n\u00eb thirrjet p\u00ebr \u00e7ipin real t\u00eb memories Flash, mbledhjen e plehrave dhe shp\u00ebrndarjen e t\u00eb dh\u00ebnave n\u00eb qelizat e memories. FTL zbaton mb\u00ebshtetje p\u00ebr shp\u00ebrndarjen fleksibile t\u00eb t\u00eb dh\u00ebnave (FDP \u2014 Flexible Data Placement), zonimin (ZNS \u2014 Zoned Namespace) dhe specifikimin NVMe. <\/p>\n
N\u00eb Flash-in e zakonsh\u00ebm p\u00ebr sistemet e jashtme, pajisja paraqet nj\u00eb kuti t\u00eb zez\u00eb, nj\u00eb pjes\u00eb e memories rezervuar p\u00ebr operacionet sh\u00ebrbyese, treguesit e performanc\u00ebs jan\u00eb t\u00eb paq\u00ebndruesh\u00ebm dhe ndodhin vonesa t\u00eb paparashikueshme p\u00ebr shkak t\u00eb aktivitetit t\u00eb brendsh\u00ebm t\u00eb kontrollorit, p\u00ebr shembull, gjat\u00eb mbledhjes s\u00eb plehrave. Ndryshe nga pajisjet tradicionale Flash, t\u00eb cilat menaxhojn\u00eb shp\u00ebrndarjen e t\u00eb dh\u00ebnave, izolimin e blloqeve t\u00eb defektit dhe mbledhjen e plehrave me firmuerin e kontrollorit, pajisjet me mb\u00ebshtetje SEF lejojn\u00eb q\u00eb logjika e pun\u00ebs n\u00eb nivel t\u00eb ul\u00ebt me \u00e7ipin Flash t\u00eb kaloj\u00eb n\u00eb an\u00ebn e softuerit dhe sistemit operativ. <\/p>\n

Qasja e propozuar n\u00eb SEF lejon uljen e kostove dhe rritjen e efikasitetit t\u00eb bashk\u00ebpunimit me pajisjen p\u00ebrmes adaptimit n\u00eb nevojat aktuale t\u00eb logjik\u00ebs s\u00eb mbledhjes s\u00eb plehrave, rezervimit t\u00eb memories dhe shp\u00ebrndarjes s\u00eb blloqeve p\u00ebr t\u00eb ulur konsumimin. <\/p>\n
P\u00ebr shembull, SEF lejon normalizimin e performanc\u00ebs n\u00eb kushte t\u00eb p\u00ebrdorimit t\u00eb nj\u00eb grumbulli t\u00eb pajisjeve t\u00eb blera n\u00eb koh\u00eb t\u00eb ndryshme me karakteristika t\u00eb ndryshme.
