Utg\u00e5van av det distribuerade replikerade blocklagret DRBD 9.1.0 har publicerats, vilket g\u00f6r det m\u00f6jligt att implementera en liknande RAID-1-array som \u00e4r uppbyggd av flera n\u00e4tverkskopplade diskar fr\u00e5n olika maskiner (spegling \u00f6ver n\u00e4tverket). Systemet \u00e4r utformat som en modul f\u00f6r Linux-k\u00e4rnan och distribueras under GPLv2-licensen. <\/p>\n

Grenen drbd 9.1.0 kan anv\u00e4ndas f\u00f6r en transparent ers\u00e4ttning av drbd 9.0.x och \u00e4r helt kompatibel p\u00e5 protokollniv\u00e5, konfigurationsfiler och verktyg. \u00c4ndringarna innefattar en omarbetning av l\u00e5sningsmekanismen och syftar till att minska konkurrensen vid l\u00e5sning i koden som hanterar in- och utdata i DRBD. \u00c4ndringen har \u00f6kat prestandan i konfigurationer med ett stort antal CPU:er och med NVMe-lagringsenheter genom att eliminera flaskhalsen som negativt p\u00e5verkar prestandan vid en stor m\u00e4ngd parallella in- och utdataf\u00f6rfr\u00e5gningar fr\u00e5n olika CPU-k\u00e4rnor. I \u00f6vrigt \u00e4r grenen drbd 9.1.0 liknande version 9.0.28. <\/p>\n

Vi p\u00e5minner om att DRBD kan anv\u00e4ndas f\u00f6r att kombinera lagringsenheter fr\u00e5n klusterknutpunkter till ett enhetligt fel-tolerant lagringssystem. F\u00f6r applikationer och system ser detta lagringssystem ut som en enhetlig blocklagringsenhet f\u00f6r alla system. N\u00e4r DRBD anv\u00e4nds skickas alla operationer med den lokala disken till andra noder och synkroniseras med diskarna fr\u00e5n andra maskiner. Vid driftstopp f\u00f6r en nod forts\u00e4tter lagringssystemet automatiskt att fungera tack vare de \u00e5terst\u00e5ende noderna. N\u00e4r den felande noden \u00e5terf\u00e5r tillg\u00e5ng, kommer dess tillst\u00e5nd automatiskt att uppdateras till det aktuella l\u00e4get. <\/p>\n

Klustret som formar lagringssystemet kan best\u00e5 av flera dussin noder, placerade b\u00e5de i det lokala n\u00e4tverket och geografiskt spridda \u00f6ver olika datacenter<\/a>. Synkronisering i s\u00e5dana distribuerade lagringssystem utf\u00f6rs med hj\u00e4lp av mesh-n\u00e4tverkstekniker (data sprids kedjevis fr\u00e5n nod till nod). Replikation av noder kan utf\u00f6ras antingen i synkront l\u00e4ge eller i asynkront l\u00e4ge. Till exempel kan lokalt placerade noder anv\u00e4nda synkron replikation, medan f\u00f6r fj\u00e4rrliggande platser kan asynkron replikation till\u00e4mpas med ytterligare kompression och kryptering av trafiken. <\/p>\n
