Linuxi tuumiku jaoks on pakutud komplekti pat\u0161e, mis implementeerib hajutatud replikatiivset plokkseadet DRBD 9, mis v\u00f5imaldab luua RAID-1 sarnast s\u00fcsteemi, mis koosneb omavahel v\u00f5rgu kaudu peegeldatud k\u00f5vakettadest, mis on \u00fchendatud erinevate s\u00fcsteemidega. Draiverit hakatakse esmalt testima linux-next harus ja viima see valmisolekuni integreerimiseks Linuxi tuumasse versioonis 7.2. <\/p>\n

Vanem DRBD variant on tuumas alates versioonist 2.6.33, mis ilmus 16 aastat tagasi. Tuumas olev kood p\u00f5hineb DRBD 8 harul, mis erineb oluliselt DRBD 9 harust, mis ilmus 2015. aastal ning ei ole protokolli tasandil \u00fchilduv. Selgus, et DRBD 9 haru arenes eraldi v\u00e4list moodulina, mis ei olnud s\u00fcnkroniseeritud tuuma p\u00f5hikomplekti mooduliga. Tuumas olev DRBD teostus oli saadaval eraldi ja j\u00e4i 10-15 aastat maha DRBD uusimast koodibaasist. Pakutud pat\u0161id on loodud, et eemaldada tekkinud l\u00f5he. <\/p>\n

DRBD v\u00f5imaldab koondada klastrite kettaid \u00fchte t\u00f5rkekindlasse ladustamisruumi. Rakenduste ja s\u00fcsteemi jaoks n\u00e4eb see ladustamine v\u00e4lja \u00fchtsena k\u00f5igi s\u00fcsteemide jaoks plokkseadmest. DRBD kasutamisel saadetakse k\u00f5ik operatsioonid kohaliku k\u00f5vakettaga teistele s\u00f5lmedele ja s\u00fcnkroniseeritakse teiste masinate kettadeks. Kui \u00fcks s\u00f5lm eba\u00f5nnestub, j\u00e4tkab ladustamine automaatselt t\u00f6\u00f6 eest vastutavate \u00fclej\u00e4\u00e4nud s\u00f5lmede kaudu. Kui rikke t\u00f5ttu katkenud s\u00f5lm j\u00e4lle saadaval on, viidatakse selle olek automaatselt ajakohaseks. <\/p>\n

Ladustamise kujundamiseks m\u00f5eldud klastrisse v\u00f5ib kuuluda kuni 32 s\u00f5lme, mis asuvad nii kohalikus v\u00f5rgu- kui ka geograafiliselt jaotatud. andmekeskustes<\/a>. S\u00fcnkroonimine sellistes jaotatud salvestustes toimub v\u00f5rgu struktuuris \u2012 andmed levivad j\u00e4rjestikult s\u00f5lmdest s\u00f5lmedeni. S\u00f5lmede kopeerimine v\u00f5ib toimuda nii s\u00fcnkroonselt kui ka as\u00fcnkroonselt. N\u00e4iteks v\u00f5ivad kohapealsed s\u00f5lmed rakendada s\u00fcnkroonset kopeerimist, samas kui kaugel asuvatel s\u00f5lmedel v\u00f5ib kasutada as\u00fcnkroonselt kopeerimist koos t\u00e4iendava kohandamise ja andmete kr\u00fcpteerimisega. <\/p>\n

DRBD 9 har tasemed transporditasemest, mis lubab luua sidekanaleid mitte ainult TCP\/IP \u00fcle, vaid ka RDMA\/Infinibandi abil. V\u00f5rreldes traditsioonilise IP-v\u00f5rgu kasutamisega v\u00f5imaldab RDMA (Remote Direct Memory Access) otsep\u00f6\u00f6rdumine teise arvuti m\u00e4lule kahekordistada replikatsiooni j\u00f5udlust ning v\u00e4hendada CPU-koormust 50%. S\u00fcnkroonitud salvestusruumi maksimaalne suurus on t\u00f5stetud 32 s\u00f5lmeline. DRBD 9-s on samuti muudetud s\u00f5lmede res\u00fcnkroniseerimise loogikat, \u00fcmberehitatud lukustamise mehhanism, lisatud toetus v\u00f5rguruumi (network namespace) jaoks, automaatne s\u00f5lme staatuse m\u00e4\u00e4ramine aktiivsuse alusel, lisatud kahesammuliste kinnituste ja mittev\u00f5tava repliikide levitamise tugi. \"Linuxi
