Deklariz\u0113tie RAID ar\u012b atvieglo augstas pieejam\u012bbas mas\u012bvu izveidi ar \u013coti lielu disku skaitu. Atjauno\u0161anas proces\u0101 p\u0113c av\u0101rij\u0101m XRAID dinamiski nosaka atk\u0101rtotas strukt\u016bras sec\u012bbu, vispirms apstr\u0101d\u0101jot zonas ar liel\u0101ku lieko inform\u0101cijas zudumu un p\u0101rstruktur\u0113jot zonas ar datiem pirms parit\u0101tes inform\u0101cijas zon\u0101m.<\/p>\n

Piem\u0113ram, ierakstu zon\u0113\u0161ana tiek pielietota SMR (Shingled Magnetic Recording) diskos, kuros joslas platums ir maz\u0101ks par magnetisk\u0101s galvi\u0146as platumu, un ieraksts tiek veikts ar da\u013c\u0113ju blakus joslas p\u0101rkl\u0101\u0161anos, t.i., jebkura p\u0101rrakst\u012b\u0161ana rada nepiecie\u0161am\u012bbu p\u0101rrakst\u012bt visu joslu grupu. <\/p>\n

Lai atbalst\u012btu zon\u0113tas ier\u012bces, XRAID izmanto XFS un Linux kod\u0101 implement\u0113to zon\u0113tu ier\u012b\u010du bloku sadal\u012bt\u0101ju (zoned allocator), kas izstr\u0101d\u0101 RT apak\u0161sadal\u012bjumu (RealTime subvolume), lai organiz\u0113tu atsevi\u0161\u0137u datu un metadatu glab\u0101\u0161anu (zon\u0101s ar sec\u012bgu ierakstu tiek glab\u0101ta tikai failu saturs, bet failu sist\u0113mas metadati tiek novietoti parastaj\u0101s zon\u0101s vai uz papildu SSD ier\u012bc\u0113m). <\/p>\n

XRAID meh\u0101nismi parit\u0101tes kontroli RAID izmanto tikai failu satura nodro\u0161in\u0101\u0161anai, bet metadatu redundance tiek \u012bstenota, izmantojot jau eso\u0161os Linux kod\u0101 eso\u0161os draiverus, piem\u0113ram, izmantojot spogu\u013co\u0161anu ar MD RAID, kas ir efekt\u012bv\u0101k maziem objektiem, ko atjaunina viet\u0113j\u0101 l\u012bmen\u012b. RAID \u012bsteno\u0161ana tiek integr\u0113ta XFS l\u012bdz zon\u0113ta ievades\/izvades apstr\u0101d\u0101t\u0101jiem, kas p\u0101rst\u0101v fizisk\u0101s zonas apak\u0161\u0113j\u0101s glab\u0101\u0161anas ier\u012bc\u0113s lo\u0123isko zonu form\u0101, l\u012bdz\u012bgi k\u0101 daudzsl\u0101\u0146u blokparakstiem.<\/p>\n

Darbs pie XRAID notiek jau pusotru gadu, un, lai gan \u012bsteno\u0161ana v\u0113l nav gatava integr\u0101cijai galvenaj\u0101 kod\u0101, t\u0101 jau ir piem\u0113rota pla\u0161ai test\u0113\u0161anai.

Lai p\u0101rvald\u012btu XRAID, r\u012bku kopai xfsprogs pievienota jauna util\u012bta «xraid» un ieviests atbalsts XRAID mkfs. Turkl\u0101t util\u012bt\u0113 zon\u0113tu disku p\u0101rbaudei Zonar pievienotas iesp\u0113jas, lai vizualiz\u0113tu lo\u0123isko zonu kart\u0113\u0161anu uz fiziskaj\u0101m zon\u0101m.<\/p>\n
