Avalikustatud on jaotatud replikeeritava plokiseadmise DRBD 9.1.0 versioon, mis v\u00f5imaldab luua RAID-1 sarnaste riba, mis koosneb mitme erineva masina \u00fchendatud ketastest (v\u00f5rgu kaudu peegeldamine). S\u00fcsteem on vormistatud Linuxi tuuma moodulina ja on jagatud GPLv2 litsentsi alusel. <\/p>\n

drbd 9.1.0 haru v\u00f5ib kasutada drbd 9.0.x l\u00e4bipaistvaks asendamiseks ja on t\u00e4ielikult \u00fchilduv protokolli, konfiguratsioonifailide ja utiliitide tasemel. Muudatused k\u00e4sitlevad lukustuste paigaldamise mehhanismi \u00fcmberkujundamist ning on suunatud lukustuste paigaldamise konkurentsi v\u00e4hendamisele DRBD-i sisend-v\u00e4ljundikoodis. Muudatus on v\u00f5imaldanud t\u00f5sta j\u00f5udlust konfiguratsioonides, kus on palju CPU-sid ja NVMe salvestusseadmetsid, k\u00f5rvaldades kitsaskoha, mis avaldas negatiivset m\u00f5ju j\u00f5udlusele, kui palju samaaegseid sisend-v\u00e4ljundip\u00e4ringuid tuli erinevatelt CPU tuumadelt. Muus osas on drbd 9.1.0 haru sarnane v\u00e4ljaandele 9.0.28. <\/p>\n

Tuletame meelde, et DRBD-i saab kasutada klastrite s\u00f5lmede salvestusseadmete \u00fchendamiseks \u00fcheks t\u00f5rketaluvaks salvestuslahenduseks. Rakenduste ja s\u00fcsteemi jaoks n\u00e4eb selline salvestuslahendus v\u00e4lja nagu sama plokiseade k\u00f5igi s\u00fcsteemide jaoks. DRBD-i kasutamisel suunatakse k\u00f5ik kohalikud kettategevused teistele s\u00f5lmedele ja s\u00fcnhroniseeritakse teiste masinate ketastega. Kui \u00fcks s\u00f5lm eba\u00f5nnestub, j\u00e4tkab salvestuslahendus automaatselt t\u00f6\u00f6tamist j\u00e4\u00e4nud s\u00f5lmede abil. Kui rikke p\u00f5hjustanud s\u00f5lm taastub, viiakse selle seisund automaatselt p\u00e4evakohaseks. <\/p>\n

Klassi, mis moodustab salvestusruumi, v\u00f5ib kuuluda mituk\u00fcmmend s\u00f5lme, mis asuvad nii kohalikes v\u00f5rkudes kui ka erinevates geograafilistes kohtades. andmekeskustes.<\/a>S\u00fcnkroniseerimine sellistes hajutatud salvestustes toimub mesh-v\u00f5rgu tehnoloogiate abil (andmed levivad s\u00f5lmedelt edasi). Sinteteerimine v\u00f5ib toimuda nii s\u00fcnkroonse kui ka as\u00fcnkroonse re\u017eiimis. N\u00e4iteks v\u00f5ivad kohalikult asuvad s\u00f5lmed kasutada s\u00fcnkroonset replikatsiooni, samas kui kaugelt asuvate asukohtade jaoks v\u00f5ib rakendada as\u00fcnkroonset replikatsiooni koos t\u00e4iendava andmekompressiooni ja kr\u00fcpteerimisega. <\/p>\n
