Linuxi tuumiku jaoks on ette n\u00e4htud patchide kogum, mis implementeerib jaotatud replikeeritavat plokk-seadet DRBD 9, v\u00f5imaldades luua RAID-1 sarnase f\u00f6deraalse s\u00fcsteemi, mille moodustavad v\u00f5rgus replitseeruvad m\u00e4luseadmestikud, mis on \u00fchendatud erinevate s\u00fcsteemidega. Draiverit kavatsetakse k\u00f5igepealt testida linux-next haru kaudu ja viia see valmisolekuni integreerimiseks Linuxi tuumasse 7.2. <\/p>\n

Vana DRBD versioon on tuumaga alates versioonist 2.6.33, mis ilmus 16 aastat tagasi. Tuumades olev kood p\u00f5hineb DRBD 8 harul, mis erineb oluliselt 2015. aastal v\u00e4lja antud DRBD 9 harust ja ei ole protokolli tasandil \u00fchilduv. See t\u00e4hendab, et DRBD 9 haru on arenenud eraldi v\u00e4lise moodulina, mis ei s\u00fcnkroonitud tuuma p\u00f5hikomplektiga. Tuumas olev DRBD teostus on olnud eraldi hoolduse all ja j\u00e4\u00e4b 10-15 aastat maha praegusest DRBD koodibaasist. Pakutud patchid on loodud selle l\u00f5he likvideerimiseks. <\/p>\n

DRBD v\u00f5imaldab klastrite seadmete \u00fchendamist \u00fcheks rikkevastaseks salvestusruumiks. Rakenduste ja s\u00fcsteemi jaoks n\u00e4eb see salvestusruum v\u00e4lja nagu sama plokkseade k\u00f5igis s\u00fcsteemides. Kasutades DRBD-d, suunatakse k\u00f5ik kohalikul kettal toimuvad toimingud teistele s\u00f5lmedele ja s\u00fcnkroniseeritakse teiste masinate kettastega. Kui \u00fcks s\u00f5lm eba\u00f5nnestub, j\u00e4tkab salvestusruum automaatselt t\u00f6\u00f6d j\u00e4\u00e4nud s\u00f5lmedega. Kui rikke t\u00f5ttu eba\u00f5nnestunud s\u00f5lm taastub, viidatakse selle olek automaatselt ajakohaseks. <\/p>\n

Klastri koosseis, mis moodustab salvestusruumi, v\u00f5ib sisaldada kuni 32 s\u00f5lme, mis asuvad nii kohalikus v\u00f5rgus kui ka geograafiliselt jaotatuna. andmet\u00f6\u00f6tluskeskustes<\/a>. Sarnased hajutatud salvestuslahendused kasutavad andmete s\u00fcnkroonimiseks mesh-v\u00f5rku \u2014 andmed liiguvad s\u00f5lmpunktist s\u00f5lmpunkti. S\u00f5lmede replikatsioon v\u00f5ib toimuda nii s\u00fcnkroonses kui ka as\u00fcnkroonses re\u017eiimis. N\u00e4iteks v\u00f5ivad lokaalselt paiknevad s\u00f5lmed rakendada s\u00fcnkroonset replikatsiooni, samas kui kaugel asuvate s\u00f5lmede puhul v\u00f5ib kasutada as\u00fcnkroonselt replikatsiooni koos t\u00e4iendava tihendamise ja kr\u00fcpteerimisega. <\/p>\n

DRBD 9 haru eristub transporttasandi abstraktsiooniga, mis v\u00f5imaldab rakendada suhtluskanaleid mitte ainult TCP\/IP peal, vaid ka RDMA\/Infiniband kasutamisel. V\u00f5rreldes traditsioonilise IP-v\u00f5rgu toimimisega v\u00f5imaldab RDMA (Remote Direct Memory Access) otse p\u00e4\u00e4seda teise arvuti RAM-i, mis kahekordistab replikatsiooni j\u00f5udlust ja v\u00e4hendab CPU koormust 50% v\u00f5rra. S\u00fcnkroneeritud salvestusruumi maksimaalne suurus on suurenenud kuni 32 s\u00f5lmeni. DRBD 9-s on muutunud ka s\u00f5lmede uuesti s\u00fcnkroniseerimise loogika, uuendatud lukustuse seadistamise mehhanismi, lisatud v\u00f5rgunimi (network namespace) tugi, tagatud s\u00f5lme staatuse automaatne seadmine vastavalt aktiivsusele, lisatud kahefaasiliste kinnituste ja uuenduste levitamise tugi mittet\u00f5kestava re\u017eiimi korral. \"Linuxi
