\nN\u00eb skem\u00eb ilustrohen komponent\u00ebt baz\u00eb t\u00eb LightStore. Klasteri i nodave punon me \u00e7iftet \u00e7el\u00ebs-vler\u00eb. Server\u00ebt e aplikacioneve lidhen me sistemin p\u00ebrmes adapter\u00ebve. Ata konvertojn\u00eb k\u00ebrkesat e klient\u00ebve (p\u00ebr shembull, fread() nga API POSIX) n\u00eb k\u00ebrkesa KV.

Potenciali i arkitektur\u00ebs<\/h2>\n

\nInxhinier\u00ebt nga MIT thon\u00eb se kapaciteti i zgjidhjes s\u00eb bazuar n\u00eb LightStore arrin 620 Mbit\/s p\u00ebr Ethernet 10-gigabit.

Aktualisht, zhvilluesit po p\u00ebrmir\u00ebsojn\u00eb disa aspekte. P\u00ebr shembull, LightStore nuk mund t\u00eb punoj\u00eb me k\u00ebrkesa diapazoni dhe k\u00ebrkesa t\u00eb vogla. K\u00ebto funksionalitete do t\u00eb shtohen n\u00eb t\u00eb ardhmen, pasi LightStore p\u00ebrdor pem\u00eb LSM.

Zhvillime t\u00eb tjera<\/h2>\n

\nN\u00eb ver\u00ebn e vitit 2018, Marvell, kompania zhvilluese e sistemeve t\u00eb ruajtjes, prezantoi nj\u00eb gam\u00eb t\u00eb re t\u00eb kontrollor\u00ebve SSD mbi baz\u00ebn e sistemeve t\u00eb intelijenc\u00ebs artificiale. Zhvilluesit implementuan akcelerator\u00eb t\u00eb m\u00ebsimit t\u00eb thell\u00eb NVIDIA n\u00eb kontrollor\u00ebt standard p\u00ebr qendrat e t\u00eb dh\u00ebnave dhe aplikacionet klient. Si rezultat, ata krijuan nj\u00eb arkitektur\u00eb autonome q\u00eb konsumon m\u00eb pak energji, krahasuar me kontrollor\u00ebt klasik\u00eb SSD. Kompania shpreson se sistemi do t\u00eb gjej\u00eb aplikim n\u00eb llogarit\u00eb periferike, analiz\u00ebn e t\u00eb dh\u00ebnave t\u00eb m\u00ebdha dhe IoT.<\/p>\n

S\u00eb fundmi, gama e ruajt\u00ebsve Western Digital Blue u p\u00ebrdit\u00ebsua. N\u00eb prill, zhvilluesit prezantuan zgjidhjen - WD Blue SSD, e cila bazohet n\u00eb teknologjit\u00eb SanDisk, t\u00eb cilat WD i bleu nj\u00eb vit m\u00eb par\u00eb. WD Blue SSD e p\u00ebrdit\u00ebsuar dallohen p\u00ebr performanc\u00ebn e p\u00ebrmir\u00ebsuar dhe efikasitetin energjetik. NVMe<\/a><\/noindex>, e cila hap aksesin n\u00eb SSD-t\u00eb e lidhura p\u00ebrmes PCI Express.<\/p>\n

Kjo specifikim rrit efikasitetin e pun\u00ebs s\u00eb SSD-s\u00eb me nj\u00eb num\u00ebr m\u00eb t\u00eb madh k\u00ebrkesash t\u00eb nj\u00ebkohshme dhe p\u00ebrshpejton qasjen n\u00eb t\u00eb dh\u00ebna. S\u00eb zus\u00e4tzliche, NVMe lejon standardizimin e nd\u00ebrfaqes s\u00eb SSD - prodhuesit e harduerit nuk do t\u00eb duhet m\u00eb t\u00eb shpenzojn\u00eb burime<\/a><\/noindex> p\u00ebr zhvillimin e drejtorive, lidhjeve dhe formateve unike.<\/p>\n

\nTregu i SSD-ve p\u00ebr Qendrat e T\u00eb Dh\u00ebnave po l\u00ebviz drejt thjeshtimit t\u00eb arkitektur\u00ebs, automatizimit t\u00eb funksionimit t\u00eb komponent\u00ebve t\u00eb ruajtjes dhe rritjes s\u00eb efikasitetit energjetik. Zhvillimi i inxhinier\u00ebve nga MIT adreson k\u00ebt\u00eb sfid\u00eb. Autor\u00ebt parashikojn\u00eb<\/a><\/noindex>, se LightStore do t\u00eb b\u00ebhet standardi industris\u00eb p\u00ebr ruajtjet SSD n\u00eb Qendrat e T\u00eb Dh\u00ebnave. Mund t\u00eb supozohet se n\u00eb t\u00eb ardhmen do t\u00eb shfaqen arkitektura t\u00eb reja, edhe m\u00eb efikase, mbi k\u00ebt\u00eb baz\u00eb.<\/p>\n
