Kutulutsidwa kwa chida chogawira chojambulidwa cha DRBD 9.1.0 chasindikizidwa, chomwe chimakulolani kuti mugwiritse ntchito ngati gulu la RAID-1 lopangidwa kuchokera ku ma disks angapo a makina osiyanasiyana olumikizidwa pa netiweki (network mirroring). Dongosololi limapangidwa ngati gawo la Linux kernel ndipo limagawidwa pansi pa layisensi ya GPLv2.
Nthambi ya drbd 9.1.0 ikhoza kugwiritsidwa ntchito kusintha drbd 9.0.x mowonekera ndipo imagwirizana kwathunthu pamlingo wa protocol, mafayilo osinthira ndi zofunikira. Zosinthazi zimabwera pakukonzanso makina oyika maloko ndipo cholinga chake ndi kuchepetsa mpikisano pokhazikitsa zotsekera mu code yomwe imayang'anira I/O mu DRBD. Kusinthaku kunapangitsa kuti zitheke kuwongolera magwiridwe antchito ndi ma CPU ambiri komanso ma drive a NVMe, pochotsa botolo lomwe limasokoneza magwiridwe antchito pomwe zopempha zambiri zofananira za I / O zimalandiridwa kuchokera kumitundu yosiyanasiyana ya CPU. Kupanda kutero, nthambi ya drbd 9.1.0 ikufanana ndi kutulutsidwa kwa 9.0.28.
Kumbukirani kuti DRBD itha kugwiritsidwa ntchito kuphatikiza ma drive a cluster node kukhala malo amodzi olekerera zolakwika. Kwa mapulogalamu ndi dongosolo, kusungirako koteroko kumawoneka ngati chipangizo chotchinga chomwe chiri chofanana ndi machitidwe onse. Mukamagwiritsa ntchito DRBD, ntchito zonse za disk zam'deralo zimatumizidwa kumalo ena ndikugwirizanitsa ndi ma disks a makina ena. Ngati node imodzi ikulephera, chosungiracho chidzapitirizabe kugwira ntchito pogwiritsa ntchito ma node otsala. Pamene kupezeka kwa node yolephera kubwezeretsedwa, dziko lake lidzabweretsedwa mpaka pano.
Gulu lomwe limapanga zosungirako lingaphatikizepo magawo khumi ndi awiri omwe ali pa netiweki yakomweko ndikugawidwa m'malo osiyanasiyana. Kulunzanitsa muzosungirako za nthambi zotere kumachitika pogwiritsa ntchito matekinoloje a maukonde a maukonde (deta imayenda motsatira unyolo kuchokera ku mfundo kupita ku mfundo). Kubwereza kwa node kumatha kuchitidwa mwanjira yofananira komanso yofananira. Mwachitsanzo, ma node omwe amakhala komweko amatha kugwiritsa ntchito kubwereza kofananira, ndipo kuti asamutsire kumasamba akutali, kubwereza kwa asynchronous kungagwiritsidwe ntchito ndi kuponderezedwa kwina ndi kubisa kwa magalimoto.
